Waterproof plugging the cable trench construction program one, analyze the reasons for the cable channel leakage Leaking water governance, we should follow the "block row combination of local conditions, hardness and softness, comprehensive treatment" principle, following preparation of the construction process. Second, the Project Overview This project is a power plant XXX waterproof cable channel maintenance. The new site look great waterproof construction professionals as follows, the project cable channel leakage, construction joints loose, ground subsidence. Resulting in the role of surface water infiltration indoor cable channel under the influence of normal use. In this case the outer structure of the positive side to do water treatment, high cost, but also reach the full protection requirements, can only be done from the back surface water treatment internal structure. This requires taking into account the waterproof layer of pressure to bear, and the combination of waterproof material with the original grass-roots issues. Now prepare the following governance programs. Grouting waterproof plugging construction methods using internal and external brush ensure seepage agent JS composite waterproof coating. Internal and External reached to ensure seamless interior concrete walls, to the effect of water seepage. Third, a construction preparation, construction of the plugging project organized my unit, according to arrange construction engineering requirements, construction personnel certificates, strictly follow the relevant rules, regulations and requirements related to the construction process. For complex and important construction itemized construction site, preparation of detailed construction plan in advance before implementation. 2, according to the progress of the construction site on schedule to complete the segment waterproof plugging task, according to the scene to determine the construction of the pipeline. Fourth, materials and machinery to prepare a major construction materials: Cyanide Ningzhu slurry ensure impermeable agent, plugging Ling, packers, rigid waterproof, JS composite waterproof coating, cleaning agents and other supporting material. 2, the main mechanical preparation: scaffolding, filling machines, drills, hammers, tongs, brush, metal pail, broom, shovel, gloves, scissors, embedded tubes. Fifth, the construction process of primary treatment → → drilling pipe (packer) → Sealing → grouting → → brushing ensure impermeable agent JS composite waterproof coating → → Nippon Paint construction completion and acceptance 1. Primary treatment: The cement residue original surface of the substrate surface clean with a stir when necessary to expose the original mill for grinding concrete structure, in order to be fully integrated with the new waterproof layer and the substrate surface, to achieve the desired water effects. 2, find the leak and Punch: The reason this works is leaking inside the concrete has cracks caused cracks to leak and special treatment from leaks between the hole and the hole can not be more than 30 cm, in order to prevent partial plugging After the occurrence of other parts of leaking. This project uses the whole plugging grouting program, leaking obvious at the distance between the hole and the hole can not be more than 50 centimeters, can not empty at the vertical drilling, to tilt punch. 3, the pipe (grouting): packer to be arranged at the leaks. Packer distance should be based on the crack size, structure and shape may be. If cracks criss-crossing at the intersection should be set packer. Cloth mouth throughout the construction site to be reasonable, to be accurate, the tubes are mounted valves for drainage and grouting. 4. Sealing: The Efficient plugging Ling watered and into a massive, dense along the seam. After plugging Ling completely solidified when used in leaks to ensure impermeable agent for processing. 5, grouting: grouting plugging materials 5.1: Key performance indicators: 5.2 Grouting: Press the formula (or custom formulations depending on the circumstances) the preparation of slurry (with a good attention to avoid contact with water). With the water pressure test in the same manner poured crack, control pressure is generally greater than the groundwater pressure 0.3 ~ 0.8Mpa, grouting should start from the bottom, when the side of the tube a slurry grouting 2 to 3 seconds after shut down a slurry valves and grouting Valve, according to one from the bottom side, and then from the side to the top, followed by gradual. Grouting using a hand pump, single liquid grouting. If the amount is too small leakage of water seepage site should double grouting pump, a water pump, a pump grouting, two pump through the collection to a tee grouting pipe into the cracks. Since the slurry enters the crack, only in presence of water to react consolidation prevent seepage outflow. If only a single pump grouting, in the case of a small amount of water seepage, the slurry can not be in a short time with plenty of water for chemical reactions to generate consolidated body, so be sure to double-pump grouting construction. 5.3 Sealing: After the slurry is completely consolidated, there is no leakage of water was observed phenomenon, the area with waterproof mortar grouting seal level. 5.4 After completion of grouting plugging, with "time to ensure" strong sealing agent sealing treatment and a large area of ??water treatment. Six, while ensuring an impermeable agent construction, ensure that the agent is impermeable moisture impermeable material manufactured by the international advanced technology and equipment, this product is a special cement and a variety of active chemicals are mixed sufficiently rigid capillary crystalline waterproofing materials , which has strong penetration ability, combined with the concrete surface after trace elements which can penetrate directly into the concrete, thus sealing the cracks and pores of the concrete and rapid crystallization of the concrete structure is more dense, aim to achieve complete waterproof construction When using the scraper to ensure uniform conditioning quickly scrape the material on the top surface, it should be done uniformly smooth. 2, strong sealing waterproofing agent - "ensure", is a highly effective moisture, permeability, sealing materials. The material is divided into liquid, solid two kinds, both gray and black one-component materials. Key performance indicators: three ingredients: a temperature of 22 ℃, pink water ratio of 1: 0.35 to 0.4 under the conditions of powder and liquid feed into the mix when the barrel will ensure that, even to the putty-like to quickly plugging stir into the clutch material into lumps. Should have prepared this time to within a mixing amount of mixed construction materials. Water can not be added after the initial setting material in use. 4, the leakage site tick chisel to expose the concrete base and clean up, check to see cracks in parts of the obvious leaks, cracks along the seam of the tick-hewn V-groove, cook mark. Significant portion of holes, around the hole clean. Stir well to ensure the area with crack sealing agent when filling them, and catch up with the trowel light (note the pre-construction to the grassroots level to fully wet saturated). When parts of the slug holes ensure that the "blocking agent" shape into a hole slightly larger than the site of blockage in the hole. 5, after scraping construction detail treatment, with a scraper or trowel scraping pressure of the first layer material, when the coating sclerosis (initial setting, the performance of hand pressure without leaving fingerprints) after spraying curing; note that the coating is not fully cured conservation must not destroy the coating. 180min after the second time pressure can scratch the paint, water saturation before scraping pressure. Scraping pressure method with the first layer, the first layer and the direction perpendicular to each other. After the initial setting of construction coatings, water conservation 48 hours, when best to use water conservation methods, in order to avoid damage to the finish. Seven joints leakage control program expansion joints (Deformation) is easy to produce special parts leakage, according to the actual situation of the Party and engineering requirements, the need for grouting cracks leak parts of waterproof plugging, again according to the specific circumstances Compression rigid waterproof protective sealant layer construction. 1, the first construction joints chisel a deep 40mm, 60mm width of a "V" seam, rinse with water. 2, the fixed channel and grouting grouting pipe: with more than 2.5 ordinary portland cement grouting channel fixed PE foam strip, at a fixed PE foam strip, every one about 50cm buried pipe grouting, grouting tube using 10-13mm of pressure rubber hose, the pipe as water pipes and as grouting works. 3 grouting plugging and sealing flexible seal waterproof construction began from the side of the polymer injection grouting material grouting pressure control between 0.3-0.5MPa, to be next to a hole grouting can stop take slurry grouting, closed valve and then from another hole plugging grouting, followed by the order, until all leaks observed grouting is completed, there are still some places such as leakage can add grouting hole from a recent leak until not so far. Before making a cut pipe sealant construction. Eight, JS composite waterproof coating construction 1, pending the completion of grouting concrete and grouting full and binding as a whole after the Packers exposed parts removed, retaining wall should be slightly lower portion of the base surface grouting mouth with ensuring After filling for construction in JS waterproof coating. 2, because the structure of concrete seepage hard, without a certain flexibility, prone to cracks, no tension, rigid waterproof, brushing the surface JS waterproof, flexible waterproof layer elastic integrally formed after the conjunctiva, with extension, the surface does not crack with concrete firmness and flexibility to achieve unity. Construction should be preceded by the JS liquid and powder material with a good pro rata, and stir evenly, no particles, brushing the first pass should be first with the more dilute the paint so that it can be a good penetration of the primary surface. To be dry before the first pass and then brush a second time, the application of a little more thick material, at intervals of four hours brushing again, this is the top of the construction project, in consideration of the thick brush easy to fall off, not one step, brushing the number should be more than three times, after the solidified coating JS conjunctiva is white elastic solid, compact formed in the roof waterproof layer, play a very good waterproof effect. 3, JS coating construction sequence: Primary treatment → brushing Yang angle pipe coating paste or non-woven glass cloth → → slightly dry brushing primer coating first waterproof coating layer non-woven paste (non-woven ride take not less than 0.1mm) → brushing second channel waterproof coating layer → brushing the third waterproof coating layer → Self-Test → cleaning → first closed water test finishes → → → acceptance second test water . 4. After JS waterproof coating layer is sufficiently conjunctiva, painted over Nippon exterior paint, interior decoration in order to achieve the effect, both waterproof and durable and beautiful. Nine, quality inspection and requirements 1, the technical performance indicators chosen waterproofing material shall comply with national regulatory requirements, the product should be reviewed with field sampling to verify the quality inspection reports or other documents related to the quality of materials. 2, waterproof layer should look smooth, no leaks. Ten, precautions and safety measures 1, before grouting grouting system response conduct a comprehensive inspection, grouting joints valves, pipes and gauges and other devices must be firm, be sure to tighten the valve head, can not cause burst pipes and strings Pulp accident. 2, should pay close attention to the grouting pressure gauges, flow, time and other parameters, and strive to a successful, large parts of the food slurry grouting method can be intermittent. 3, in the cracks may occur when grouting plasma leakage, take slurry phenomenon, which belong to the genus closed due to lax, should stop grouting, closed tight before continuing. 4, when a sudden increase in pressure grouting Sometimes, this pressure is false pressure piping systems or components due to temporary partial blockage caused by the entry with the higher pressure will be rushed to open the blockage, the pressure will drop, which is a normal phenomenon. 5, when the grouting must pay attention to maintain good ventilation, construction site should be away from fire, non-smoking, prevent fires.
