We are willing to cooperate with your company pleasant, mutually beneficial and win-win. First, the preparation according to 1, the construction site situation; 2, "water engineering acceptance" GB50208-2002; 3, "Waterproofing technical specifications" GB50108-2001; 4, existing national specification. Second, the construction principle and method using high-pressure grouting plugging water treatment approach. 1. Determine waterproof plugging solution: site survey must be carried out before plugging find out the construction site situation, analyze the causes of water leakage, identify leaking parts, cracks or perforated width, length, depth, and throughout the case, and Learn leaks rain and sunny measured leakage flow and flow rate, etc., through the full investigation, the right to develop sealing solutions, do the preparatory work. 2. Material Features: oily polyurethane adhesive and rapid plugging water that reaction, because the water involved in the reaction, the slurry is diluted with water is not washed away, which is the other filling materials do not have the advantages of the slurry under pressure, irrigation gaps or holes into the concrete, while the gap around the penetration to continue into the concrete cracks, forming a network structure into small density, moisture content of the elastomer, and a good ability to adapt to a variant, the sealing is good. 3, the design and layout of grouting hole hole: Hole Filling holes and inclined holes are two forms of roulette, be selected according to the actual situation and needs, when necessary, both. (1) Filling hole design: the location of the grouting holes should be made void holes and leaking cracks intersect, and choose the amount of leakage is greatest. (2) Hole principles: location and number of grouting eyelet, to be based on different leaks | undoubtedly Testing Network | make reasonable arrangements to export the leakage for the purpose of concentrating Hole leaks, cracks big, the water flow hole away from the big, small gap is small pitch. 4, drilling a visual construction conditions using manual and mechanical methods, usually by hand punching and mechanical drilling and use. 5. Check the operation of filling equipment and piping, check the mouth consolidation pulp strength, clear crack, further setting the filling parameters (such as gel time, grouting pressure and with the amount of pulp, etc.). 6, grouting: grouting is the central link of the entire chemical grouting, after all the preparatory work must be finished. Before filling organized division of labor, fixed positions, especially the need for skilled personnel to operate full-time. (1) Before filling the entire system to conduct a comprehensive inspection, filling machines under normal operation, the pipeline flow situations before grouting. (2) The general bottom-up filling the vertical joints, horizontal joints from one end to the other end or toward the middle from the two filling; focus should be on the leak leaking largest hole grouting. End Filling: In the pressure is relatively stable, and then continue filling 1-2 minutes either end of grouting, disassemble pipeline ready for cleaning. Sealing: after checking without leaking, remove the grout head, with cement mortar and other materials will 孔补平 trowel. Note: Enter the slurry pipe must have sufficient strength, easy assembly and disassembly. All operators must wear the necessary labor protection. When filling, operation of the pump should always pay attention to the amount of slurry poured while observing pressure changes. Usually a sudden increase in pressure may be due to the slurry solidification, pipe blockage or because of the slurry gradually filling settlement joint, then immediately stop filling. Pressure steady increase, but still within a certain pressure is, and this was normal. Sometimes the pressure drop, this may be due to being rushed to open the pores, the slurry poured into the settlement joints caused by the deep, then sustainable grouting. With a large number of slurry into the gap, the pressure will gradually increase and stabilize. Another reason is due to the decrease in the pressure seal joints or pipe fittings plasma leakage caused by the need for timely stop filling, for processing. Sometimes, because of the pump pressure, the slurry was crushed into the depths of the settlement joint, so that the loss of a large number of slurry, then the slurry consolidation time can be adjusted so as to shorten the setting time or intermittent slurry grouting method to reduce losses. Grout used equipment, pipes and drums must be separately identified. Should be prepared prior to grouting cement, water glass and other fast plugging material for timely processing pulp slurry leakage run situation. After each filling, it must be cleaned of all equipment and piping, apply grouting after the 1: 2 cement mortar grouting hole closed. Third, the construction steps: 1. Determine the leakage points; 2 clean up leakage base; 3 drilling; 4 cleaning; install grout mouthend 5; 6 high pressure pouring oil polyurethane; 7 observe and trap; 8....... Demolition of filling the mouth; 9 slot repair; 10 surface restoration.
