The construction program and product pricing. Willing to cooperate with your company happy, mutually beneficial and win-win. First, on the basis of an establishment, construction site conditions; 2, "waterproofing Acceptance" GB50208-2002; 3, "engineering waterproof technical specifications" GB50108-2001; 4, existing national specification. Second, the construction principles and methods using high-pressure grouting plugging treatment approach. 1. Determine waterproof plugging solution: site survey must be carried out before plugging find out the construction site, and to analyze the reasons for water leakage, identify leaking parts, cracks or perforation width, length, depth, and throughout the case, and Learn leaks rain and sunny, and the measurement of leakage flow and flow rate through the full investigation, the right to develop plugging program, do the preparatory work. 2. Material Features: oily polyurethane adhesive quickly plugging that reaction with water, 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, irrigation gaps or holes into the concrete, while the gap around the penetration into the concrete continues slit, forming a network structure, the density becomes small, the aqueous elastomer, with good ability to adapt to variations, good sealing. 3, the design and layout of the hole filling hole: cloth hole filling holes and inclined holes have straddle two forms, to be selected according to the actual situation and needs and, if necessary both. (1) filling holes Design: Filling the hole location should make holes and leaking cracks intersect the gap, and the election in the largest leak place. (2) cloth hole principle: the location and number of grouting hole, to be based on different leaks | undoubtedly Testing Network | make reasonable arrangements to export the leakage for the purpose of concentrating cloth hole leaks, cracks big water flow the hole away from the big, the small gap is small pitch. 4. visual punch construction conditions using manual and mechanical methods are generally manual drilling and mechanical drilling and use. 5. Check operation of filling equipment and piping, check consolidation mouth pulp strength, clear crack, further setting the filling parameters (such as gel time, grouting pressure and with plasma volume, etc.). 6. Filling: filling the entire chemical grouting central link, after all the preparatory work must be finished. Before filling organized division of labor, fixed positions, in particular, need a full-time skilled personnel to operate. (1) Before filling the entire system to conduct a comprehensive inspection, filling machines under normal operation, the pipeline flow situations before grouting. (2) For the vertical joints are generally bottom-up filling, horizontal slit from one end to the other end or the middle from two filling; focus should be on the leaking leaking largest hole grouting. End Filling: In the pressure is relatively stable, and then continue to the end of the grout can fill 1-2 minutes and remove the pipe ready for cleaning. Sealing: when there is no water leakage inspection, remove the filling 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 supplies. When grouting operation of the pump should always pay attention to the amount of slurry poured while observing 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. 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, must be cleaned of all equipment and pipelines, grouting applications after the end of the 1: 2 cement mortar grouting hole closed. Third, the construction steps: 1. Determine the leakage points; 2 clean up leaking base surface; 3 drilling; 4 wash; 5 Install grout then the mouth; 6 perfusion pressure oil polyurethane; 7 observed and trap; 8....... Demolition filling mouth; 9 slot repair;. 10 surface water shutoff Liyang recovery plugging the most professional
