A water trap construction program, Project Overview: 1, Project Name: XXXXXX libraries water trap works 2. Construction Location: Bo plaza within 3 XXXXXX, engineering requirements a) duration requirements: Planned duration: 60 calendar days (the actual start time started to make the tender or issued by the Commissioner of the company stated time). 2) Quality Standard: meet the national or industry quality inspection and assessment of the eligibility criteria, access Dongguan model works fine. 3) safe and civilized construction requirements: a "good model for safe production and civilized construction site." Second, prepared on the basis: "Roof Engineering Quality Acceptance" (GB 50207-2002); "roof engineering and technical specifications" (GB50345-2004); "People's Republic of China Construction Law"; "construction safety inspection standards" JGJ59-99 and related to water requirements. Third, the construction preparation: (1), project director a person, a human quality, technical one, safe one person, one person engineering team leader, construction workers uncertain, according to the amount of the deployment of field engineering and construction. Construction workers are trained. Project manager and technical director to have a major job card. Fourth, prepare tools: high pressure air gun, high pressure water jet machine, broom, plastic drums, electric mixing drill, special mixing head, roller blades, brushes, foam concrete units and other related tools. Five, according to the site to observe the reason the roof leaks leaks A, roof parapet are all made of hollow brick building, due to the temperature difference causes and roofing concrete and brick parapet inconsistency causes shrinkage cracks leaking into the exterior wall. B, the original construction of the roof fell into the mouth of the unit will be installed too high can not be effectively discharged water will cause the floor roof water. C, the original waterproof material used improperly or waterproof contractor use of counterfeit waterproof material, waterproof layer leads to premature aging, deformation, rupture and leakage. D, roofing insulation material used improperly, should not be used with high water absorption of cement perlite insulation. E, roofing protective layer by design do not find the slope leading to poor drainage construction. F, roof parapet waterproof layer rolled highly enough. Six control measures (a) roof waterproofing layer specific approach based on the actual situation must first original waterproof roofing insulation layer to its structure eradicate all floors, including: (①40mm cement mortar layer; ②3mmSBS modified bitumen membrane; ③ The average thickness of 100mm to find the slope of cement perlite insulation layer; ④40mm fine stone concrete cover) → The original arc angle overcast parapet eradicate → parapet plaster layer eradicate 500mm high, and leave drip puzzle, will reduce the water inlet 50mm → first negative angle hewn "V" shaped groove → with "plugging Ling" seal → polymer cement mortar to find the slope layer 1.5 ~ 2% → negative angle grant arc radius → negative angle R≥50mm do 3mm " gold raincoat "brand polyester tire CPS additional layer of self-adhesive waterproof membrane (500 wide) → 3 + 3 thick wet laid" golden raincoat "brand self-adhesive waterproofing membrane → CPS cast concrete foam insulation layer (by 2% find the slope). Construction waterproof layer should be noted: first layer waterproofing membrane should be used cement paste + powder waterproofing membrane (wet laid), using gas heating between the second layer and the first layer. Construction situ foam concrete should be noted: first install 3mm thick extruded plate (left dividing joint use) along the parapet around, because the foam concrete density of 800 ~ 1000kg / m so 48 hours after application to the Master walk, every 3 m × 3 m must be set up sub-lattice seam. VII, Section I of roofing construction technology waterproof roofing project is the construction of any building project focused on water, according to the actual situation of the project, the design of the project to determine the roof waterproof layer is mainly composed of 4mm thick SBS modified bitumen waterproofing membrane material waterproof layer. A waterproofing membrane preparation before construction work 1) the upper part of the construction process in preparation for acceptance before construction, fill in the information hidden acceptance after passing under the procedures before beginning construction. Waterproofing membrane in accordance with the construction sequence: first paving horizontal, vertical wall after paving. To both sides of the junction cross lap, the order from the top down the wall construction. Construction procedures: Acceptance grassroots grassroots cleanup ____ _____ ____ brushing cold base oil corner site posted an additional layer of waterproofing membrane _____ ______ paving closed head ?? membrane waterproofing membrane _ Construction Quality Inspection _____ acceptance. 2) material preparation a. Waterproofing material must have a product quality certification, coil factory certification, material certificates, quality inspection report. After entering the material according to the requirements of sampling inspection, after passing through the report approved before construction supervision. b. waterproofing membrane, primary adhesives, adhesive membrane after entering the store to be classified a dedicated warehouse storage location to be identified and set fire equipment. 3) technical preparation a. To be familiar with the drawings, understand the construction process of cold roll bonding method, according to the construction schedule and project department of drawings, reasonable arrangements for materials, equipment, personnel entering the construction. b. Press the construction program and technical regulations for operators of technical, safety tests, and operating instructions issued. c. to master the use of waterproof material performance and technical indicators, such as yin and yang angle waterproof practice to focus on specific parts of the control horn parts for cement stucco female character angle, and then the upper waterproof construction, and have spilled water gradient, Yin corner site shall catchment; Yang angle parts to add additional layers of dual protection; for parapet parts: a high wall in the 250-300 range to the top of the coil to be paving (coil must cover the top), for the high wall at 300, must be slotted Stones roll on vertical height of the wall 250, coil pressed into the groove, the upper 45 degree angle aluminum layering crushed (anchor rivets), aluminum layering and wall seams silica gel closure. d. prepare technical documentation and construction process of waterproofing covert inspection records. 4) Prepare equipment 5) waterproof grassroots and working conditions a. Waterproof substrate should be hard without hollowing, right from the sand, cracks, loose, out gray, uneven processing defects, its surface smooth. Should be made of the corner arc or obtuse. b. waterproof base surface must be dry, clean, moisture content of not more than 9%, the detection method for the 1m2 membrane flat on the leveling layer, standing 3-4 hours, opened the inspection cover parts, sheet no watermark can be. . c to ensure the normal operation and construction Stones roll quality, should be at 5-35 ℃ temperature construction; rain, snow, frost, fog or atmospheric humidity, and strong winds are not open jobs. . d To ensure water quality, the following conditions should be met before construction: waterproof materials manufactured products must be accompanied by certification, and to deal with the main performance indicators of qualified reinspection; waterproof construction of the operator must have a waterproof professional qualification certificates. 2 construction program and construction points a construction program: the grassroots check → cleanup patches (with a 1: 2.5 cement mortar to find slope) → brushing the cold base oil → Paste additional layer and at the outlet Stones roll elastic line → → Pressure side, playing sealed plastic → cleaning, inspection, repair → quality inspection (water test) → post-mortem inspection → protective layer construction. b Construction Points: To reduce the yin and yang angle and a large area of ??the joint, the first coil along the longitudinal direction can be configured to minimize the corner seams. According to the web site of the configuration, start from flowing downhill slope pop standard line, so long coil perpendicular to the slope with water. And based on the size of the web width and lap joint, at the grassroots level will line playing well. Stones will be carried to the starting end of the web, playing good alignment pink line, while heating fuser roll edge shop, followed by a man with a hand press roll rolling pressure, exhaust air, solid cement paste. Paste the web width fitting joints, coil generally 100mm, will roll the seams with a blowtorch first 16mm diameter steel rod heated to redness along the seams with a steel rod stroked over, stroked at the same time with a blowtorch again heated steel rod were hot side, it should be noted steel rod can not stay in one place for too long to avoid burn waterproof layer. Close the first coil end processing, in order to prevent peeling or leakages coil tail end, the end of the closing head must be closed with a sealing material, when the sealing material is cured, and then at the end of the closing head brushing a layer of waterproof coating material, in which When the coating layer is not completely cured, you can use 107 plastic cement mortar pressed seam closed. Paste former lap joint first with gasoline to scrub clean the surface of the lap roll, then roll seam brushing glue, paste side edge gluing and flattening paste real, not leak stickers and Alice. Detail processing: The yin and yang angle, through the waterproof layer pipes and other parts of the roots, before Stones roll should do first reinforcement treatment, with the exact location of the root to take effective measures, such as: Yang angle available additional web site posted Real firmly affixed. When additional Stones roll, not taut, wrinkle-free shop to the natural pine can be; and if the root portion of the tube, in the case of smaller diameter, coil notches real pasting stickers should be first in diameter around within 500mm coated with a thick coating for enhanced processing quality, according to the diameter of the coil and then be open hole in the pipe through the casing paving roots, and then seal sealing material. Waterproof membrane with a parapet and corner of the grass-roots, should be circular arc radius of 20, the Pan-water height should be 250 ~ 300mm. Roll pan of water to close the head opening in the wall slotted membrane pressed into the groove, covered with a metal plate (metal material is less than the width of the Department 50), with a sealing material sealing. Because of waterproofing membrane puncture resistance is poor, so waterproofing membrane after completion of inspection, according to design requirements in a timely manner to make the protective layer, which is very important, but also prevent membrane aging. 6) Construction Notes a. Drawback waterproofing membrane is an extension of small, poor wear resistance, and therefore must take the appropriate measures to remedy. b. the choice of appropriate technology, according to the different parts of the waterproof roofing project in order to use empty shop, bar and point stick craft stick better, so compared with full-paste method, increasing the area of ??the membrane deformation participation, increases the membrane relative to the absolute elongation values, thus effectively compensate small membrane elongation, deformation crack prone drawbacks. . c construction measures taken: a waterproof layer after passing inspection, in a timely manner protective layer can compensate poor puncture membrane defects, but attention is not necessary due to construction waterproofing membrane puncture, or you must repair tight, leaving risks, do protective layer. d. Also note that when the waterproof layer construction, construction workers should strengthen the sense of quality, rendering equipment damage membranes, rendering heavy smashed membrane, do not wear nail palm shoes or hard-soled shoes with silt construction, waterproof layer construction After the Master shall within two days. e. materials transport and storage should stand up and be prohibited fireworks and sun exposure, dumps away from heat and flammable materials. f. Construction of the temperature to the optimum, not less than 5 ℃ and 35 ℃ temperature greater than 10-25 ℃ construction, rain, snow, windy days, not construction. g. the construction site to prepare adequate fire-fighting equipment and fire fighting facilities, fire roads open, especially when using adhesives special attention to fire safety. 3 pipeline leakage prevention measures through the floor when a) set aside strictly control the size of the hole axis to minimize bias aside hole. 2) hole in the tube plugging plaster work full-time while going to school operations, cleared debris mortar section, wet with water. Water using a template rather than supporting top-hanging mode selection (to prevent water infiltration along the hanging wire,) with the additions of fine aggregate concrete expanders carefully tamping, pouring to 1/2 the thickness of 24 hours when tested infiltration leakage resistance, brushing waterproof coating layer after passing the test in order to continue pouring upper part. In making the ground root canal parts made of 2cm above the ground water table (note appearance). In addition to the above there are parts of the casing fill holes program, its upper casing above the ground must 2cm, filled with waterproof filler between the casing and riser. 3) This measure also applies to the floor drain, drain, toilet risers place. 4) through the wall of the pipe with waterproof material enhanced seal. 4 roof tiling require special parts of a, the Stones to roll cornice cornice cut ends after Sarkozy pressed into the groove, the groove and then filling them with sealant dense. As with layering (20mm wide steel sheet, etc.) or with a gasket with nails, nail should knock the groove, nail tip cap and coil seal with a sealing material. Front gutter, gutters and fall-mouth membrane laid on the fall-mouth should be sealed. When buried Mizuochi cup, cup and standpipe connections Mizuochi socket application sealing material filling them dense, preventing the parts produced phenomenon when pouring rain. By adding an additional layer of fill around the web within the range of fall-mouth diameter 500mm layer thickness of less than 1.5mm, fall-cup with the primary contact point should be left wide 20mm, 20mm deep grooves, filling them with sealant. Because gutter, gutters large parts of the water flow, water level often affected by rainfall or immersion, and therefore should be used at the gutter sealant or sealing groove corner (negative angle), followed by a layer of additional volume required material layers. Stones roll gutter or gutters should ditch the beginning, from the fall-mouth Sunchon ditch paving laid side by side scraper scraping pressure from the center to the sides of the ditch, and drove out the bubble to make the Stones roll flat watershed direction paste dense. Such as when the ditch too wide, there will be a longitudinal lap seam, seams must take sealed with a sealing material. Fall-mouth to spread the layers of coil and an additional layer shall be attached to the cup, with a rain cover to the chassis pressed between the bottom plate and the membrane should bear full rubberized material to be bonded, sealed around the bottom of the plate fill seal material. b, the pan of water and close the first pan of water coil means and vertical wall portion of the corner of the roof. These parts of the structural deformation, susceptible to sun exposure, so in order to enhance the durability of joints waterproof layer, usually to add a layer of membrane in these parts as an additional layer. Stones roll pan of water before the site, take a test shop, will leave enough length coil facade, paving the plane roll to the first corner, and then paving facade roll from the bottom up. As Xianpu facade membrane, due to its own weight membrane, membrane tension tight facade, paving process is easy to produce Alice, hollowing, shedding phenomenon. Stones roll after the completion of the cut ends together. The use of reserve groove closed head, all the pressure will tip into the groove, with layering nail flattened clothes, and then seal the sealing material, and finally wiping seal groove with cement mortar. If you can not set aside the groove, the gasket should be used with nails or metal layering will be fixed on the coil end walls, seal with a sealing material, and then the metal or synthetic polymer membrane layering pieces with nails covered with pressure operation between the cover and sealing up the wall with a sealing material. Pan of water at the pressure of the metal, the highest ≥250mm. c, exhaust pipe exhaust hole and stretched out roof and roof angle holes at the web paving methods and stand at the corner of the wall and roof similar, the difference is that there should be no reverse flow direction Croucher, exhaust hole overcast corner Coil adding additional layers, the upper notches cross posted solid. Stones roll roofing and pipes protruding exhaust hole is similar, but it should be paved two additional layers. Waterproof layer paving, asphalt upper truss flax or thin wire, and finally sealed with a sealing material, or welding on steel sheet pan of water. Additional layer coil cutting method, see fall-mouth approach. Roof flashings pipeline height ≥250mm. d, after the yin and yang, yin and yang angle at the corner grassroots use glue sealant sealer angle on each side 100mm, additional holes and a layer membrane layer, cut joints with sealant sealing after paving. e, the high level of inter-house for low cross across the roof of a low free-draining across the roof, in part by water erosion method should be used to add a layer of glue over the entire width of the sheet, and then poured wipe width 300 ~ 500mm, thickness of 30mm cement mortar or tiling material to strengthen the protection of the same size. Such as organized drainage, downspouts additional reinforced concrete under water dustpan, should base paste, place smoothly. f, peremptory norms provisions: roof slope shall meet the design requirements Stones roll direction should meet the following requirements: When the roof slope is less than 3%, should be parallel to the roof membrane paving; roof slope at 3% to 15%, Coil Stones can be parallel or perpendicular to the ridge; when the roof slope is greater than 15% or shake roofing, bitumen membrane roof tiling should be vertical; polymer modified bitumen and synthetic waterproofing membrane may be parallel or perpendicular to the ridge Stones; not perpendicular to each other on the lower membrane Stones. g, lap roll width should meet the following requirements.
