Our company specializes in sealing technology: Changzhou sewers plugging company "Polymer grouting grouting waterproof plugging technology." My company uses a professional waterproof anti-corrosion materials manufacturers and a number of research institutions for many years developed techniques to a variety of imported chemical materials, according to the construction of water pressure is almost the size of the ratio of the viscosity of water into the same liquid, good permeability, can be injected 0.1 mm slit in the concrete under pressure and very humid environment quickly gather. Setting time can be accurately controlled with the ratio within a few seconds or a few minutes in the water speed of pressure, rapid condensation of water flow and more cases. Good permeability, shrinkage after swelling with water, insoluble in water, kerosene, gasoline and other organic solvents, acid, alkali, bacteria erosion will also affect post from atmospheric conditions, there is a certain strength, elasticity and transformer, Shelf use more than a decade. Tensile strength, Construction had been plugging the crack mouth, and later appeared normal settlement or dislocation cracks also no leakage. The key is to waterproof plugging cracks leak handling, according to the degree of the reasons for the occurrence of cracks and structural effects, etc., Changzhou sewers plugging waterproof plugging a high pressure grouting program, prepared on the basis 1, XXX basement ( -1F) wall waterproof plugging engineering technical requirements 2, waterproof technical specifications [Project] GB50108-2001; 3, [acceptance] waterproofing GB50208-2002; 4, existing national specification; 5, the construction experience of similar projects. Second, the basement wall waterproof plugging using pressure grouting methods: (1) major construction equipment: the F-512 imported micro-electric high-pressure grouting machine. The device has a self-priming feed system can be upgraded to 4500psi (300 kg / cm 2) than the working pressure in 3 to 6 seconds, the liquid slurry sealing agent can be effective perfusion minor cracks to 0.1 mm, the water stanch Construction effect is more lasting and effective than traditional methods. Selection (2) Material: Plastic Material Material characteristics: rapid plugging hydrophilic polymer materials that react with water glue, because the water involved in the reaction, diluted with water slurry is not washed away, which is the other filling materials do not have the advantages of the slurry under pressure, poured concrete gaps or holes, around the same time to penetrate the slit, the slit continues into the concrete, eventually form a network structure, the density becomes small, elastomeric aqueous, have a good ability to adapt to variations , sealing is good, no chlorine ions are not within the RC structure reinforcement corrosion damage, after construction is completed surface spills clear and simple. (3) chemical grouting waterproof plugging technical working mechanism: high-pressure chemical grouting plugging technology is the use of continuous high-pressure grouting machine produced chemical feed liquid poured into the concrete inside the gap, and the gap of the water completely squeeze out the completely fill the gap, achieve the purpose of sealing. Our waterproof so-called "filling" is the chemical grouting, chemical grouting generally refers to chemical materials prepared by slurry grouting mouth buried by drilling, the use of pressure injected into cracks in the structure, so that the diffusion, coagulation, to waterproof, blocking leak, reinforcement, reinforcement purposes. Third, chemical grouting waterproof plugging construction process 1, the construction process: determine the leakage point → clean up leaking base surface cleaning → → → milling installation grout joints connected perfusion pressure foaming mouth pulp → → → trapping observed filling the mouth → → split groove → Check → acceptance hole repair 2, construction elements (1) quasi-seepage point play, the seepage area, clean up. (2) with a rapid sealing agent embedded grouting tube spacing should be based on the actual circumstances, generally about one meter. (3) with an electric high pressure injection pump, the water-soluble polymer injection grouting plugging the gap from the grouting concrete pipe joints, until the pressure does not enter until (injection rate ≤0.011 / min) closes the valve, 24 hours after circumcision (removal) grouting Tsui. (4) In order to achieve long-term water purposes, and then in the plane surface construction brushing JS waterproof layer. (5) grouting is completed in a timely manner with solvent cleaning equipment and tools. (6) the construction site to maintain ventilation, avoid fire, fire is strictly prohibited. 3, high pressure grouting plugging construction method (1) of this construction method is the use of huge high-pressure perfusion machine generated, the material sent to the middle of the wall of the gap, the intermediate material is part of the center to the edges, and rapid response materials and water After hardening, the gap reached tamped foundation reinforcement, plugging seepage effect. (2) high-pressure grouting machine used in this construction method, perfusion pressure, flow, fast sealing, indeed effective blocking hydraulic method. (3) Method of perfusion-point of the perfusion was started from the central position of the structure, especially for a thickness greater than 1000px more concrete wall, it is fast and efficient sealing work using the present method. 9 Notes: (1) transport slurry pipe must have sufficient strength, easy assembly and disassembly. (2) All operators must wear the necessary labor protection supplies. (3) filling, operation of the pump should always pay attention to the amount of slurry is poured, while observing the pressure changes. General may be due to a sudden increase in pressure slurry solidification, slurry pipeline blockage or because of the gradual settlement joint filling, then immediately stop filling. Pressure steadily rising, but still within a certain pressure, the point is normal. Sometimes the pressure drop occurs, this may be due to being rushed to open the pores, the slurry poured into the settlement joints caused deep, this time for sustainable grouting. With a large number of slurry into the gap, the pressure will gradually increase and stabilize. Another reason is due to the pressure to reduce seam sealing pipe joints or plasma leakage caused by the need for timely stop filling, for processing. Sometimes, because of pump pressure, the slurry into the depths of the hydraulic settlement joint, so the loss of a large number of slurry, then the slurry consolidation time can be adjusted to make it shorter setting time or batch slurry grouting method to reduce losses. (4) used for grouting equipment, pipes and drums must be separately identified. (5) should be prepared prior to grouting cement, water glass and other fast plugging material, for timely processing pulp slurry leakage run situation. After (6) each grout must be cleaned of all equipment and pipelines, grouting applications after the 1: 2 cement mortar grouting hole closed. Fourth, the advantages of Changzhou sewers chemical grouting waterproof plugging plugging construction 1. Pressure is high and reliable, allowing chemical grout completely into tiny cracks in concrete structures deep inside, good sealing effect. 1. Filling liquid technology is mature, full range, basically have achieved the production of finished one-component, without on-site deployment, stable quality, can be used to open the barrel. Slurry chemical resistance, after curing non-toxic, environmentally friendly, can be permanently waterproof. 2. The construction process is simple and easy. Construction speed, sealing effect is immediate, once and for all. Labor intensity, construction efficiency is 5 to 10 times that of traditional construction methods, the traditional approach can not match. 3, the construction subject to seasonal weather restrictions, can be used for a variety of projects, including the maintenance and repair projects, drinking water projects. Fifth, waterproof mortar construction process 5.1 Basis of Preparation: 1. Party to provide design drawings and site requirements of two underground waterproof construction quality acceptance (GB50208-2002) 3, Concrete Structures Construction Quality Acceptance (GB50204-2002) 4 building construction quality acceptance of uniform standards (GBJ300-2001) 5, this project basement structure, construction plans, engineering negotiating record 5, the construction organization design 2, material requirements and construction preparation 2.1 The main equipment: 2.1.1 Cement: is appropriate number above 32.5 ordinary portland cement, slag cement can also be used when there aggressive media effect, the design requirements should be selected. 2.1.2 Sand: The sand shall not contain debris. Clay content should not exceed 3%, must live 3 ~ 5mm aperture sieve before use. 2.1.3 polymer waterproofing agent, shall be according to the product instructions for proper use. 2.1.4 The main equipment: gray board, iron trowel, trowel Yang angle, half vats, wire brush, a soft brush, character by foot, hammer, chisel tip, twist chisel, shovel, broom, wooden trowel, scraping bars and so on. 2.2 Operating conditions: 2.2.1 The structure of acceptance, acceptance procedures have been run. 2.2.2 good drainage during construction of underground water, until the water until the project is completed. Drainage, rainfall measures should construction program implementation. 2.2.3 basement door window, set aside holes, piping detail import and export processed. 3, the operation process 1, process: walls, floors wet sprinkler primary treatment → → → wiping brush cement paste waterproof mortar → conservation 2. Primary treatment: If a cellular concrete wall and loose concrete, to tick off, washed with water clean and smooth with cement mortar 1:3 or 1:2 dry hard cement mortar twist reality. Surface oil with 10% aqueous solution of caustic soda to scrub clean the concrete surface should be cutting hair. 3. 3.1 waterproof mortar construction, concrete and mortar foundation underside waterproof layer: 3.1.1 Cleanup grassroots: cleaning the cushion loose concrete, mortar and other clean, protruding bulge removed. 3.1.2 brush cement paste: Mix cement: latex = 1:0.05 (weight ratio), plus the amount of water mixed with synthetic porridge-like, spread out on the ground, even with a broom to sweep again. 3.1.3 wipe waterproof mortar: mix with cement: sand-: Latex 1:2: 0.35 (weight ratio). Marinated mortar fell on the ground, with the bar ruler evenness, wood trowel Junpei, iron trowel pressure again before the final setting of mortar tie collection of light compaction. 3.1.4 be reached 12MPa protected waterproof mortar layer of fine aggregate concrete construction. 3.1.5 Conservation: there is a certain strength to be ground, the surface of the lid or straw bags sacks moist regular watering, curing time depends on the temperature conditions, and generally 7d, slag cement not less than 14d, this period shall not be affected by static water pressure. 3.2 concrete wall concrete and mortar waterproof layer 3.2.1 brush cement paste: Mix cement: latex = 1:0.05 (weight ratio), plus the amount of water mixed with synthetic porridge-like, with a soft brush brushing the surface at the grassroots level uniform, then wipe the bottom of waterproof mortar.
