 Cesspool waterproof plugging plugging big welcome to visit the new company! The company dedicated to provide you with the best quality service! National toll-free 24-hour hotline: 13961999789 Business Service Hotline: 15862087268 The company has offices in the country: Eastern Region Northern Region Southern Region Central District, Northwest meet your company's needs, you can receive a call the day arrived at the scene to provide satisfaction... The construction program and product pricing. Willing to cooperate with your company happy, mutually beneficial and win-win. First, the preparation according to a specific situation of the project site survey: the discovery of partial basement wall leaks; 2, GB50108-2001 "underground waterproof engineering technical specifications"; 3, GB50208-2002 "underground waterproof construction quality inspection standards"; 4. The provisions of existing national norms. Second, the current status of construction of an underground garage construction area # 23031㎡, waterproof rating of Class II, fortification practices for open-cut method of underground water projects, the main use of dense graded waterproof concrete, its impermeability grade selection C35P6 waterproof construction with external practices ; outside of the basement wall selection 02J301 Atlas Pg10 number 25,26,27 waterproof construction practices, waterproof material thickness of 1.5 HY120 series of polyethylene fiber (polyester) waterproofing, sidewall protection layer 40 thick polystyrene board selection. 1 # underground garage floor surface elevation of -5.7m, roof surface elevation of -1.8m. From my unit construction (14 to 30 axis) of floor space for 13052㎡, from east to west 128m, from north to south 143.5m, west and is connected II tenders, south, east and north sides are in the basement retaining walls, east and south, respectively, which have a longer length of straight concrete wall, east length 74.5m, frame column grid size of 6000 to 7800㎜ south length of 82.6m, the frame size is 8400 column grid. At this stage in the basement to the south and east of earth backfill -1.8m (with a # underground garage roof surface flush). After the earth backfill underground garage found a # south and east of the long straight wall cracks leak water, distance 1.5 meters to 2 meters. Third, the construction principles and methods of selection of high-pressure polyurethane grouting plugging oily water treatment methods. 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, the material characteristics: rapid plugging oil polyurethane glue with water immediately react, 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 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, the aqueous elastomer, with good ability to adapt to variations, good sealing. 3, the construction steps: 3, the construction steps of: determining the leakage point 4, grouting hole hole design and layout: 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: location and number of grouting hole, the need for reasonable arrangements depending on the leaks, leaks to export for the purpose of concentrating cloth hole leaks, cracks big, big water flow the pitch, a small gap the pitch is small. 5, visual punch construction conditions using manual and mechanical methods are generally hand-drilling and drilling machinery and use. 6. 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.). 7, 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. Pressure test using high-pressure grouting machine, concrete structure shall not exceed pressure range (usually 4 ~ 8MPa). (2) to the filling hole perfusion chemical grout. Hole one by one continuously. After the start of the pulp adjacent holes, keeping the pressure of 3 to 5 minutes, you can stop filling this hole, changed the adjacent grout injection holes. After all the holes are filled finished, return to the previous first filling hole, again in order to ensure maximum pressure grouting. Wall filling the order was from the bottom up, horizontal slit from one end to another, or from both ends toward the middle filling; leakage should first concentrate on the largest holes leaking grouting, wait until all the holes after filling is also a return to the previous The first filling hole recharge time. 8, the end of the filling: In the pressure is relatively stable, and then continue to pour 1 to 2 minutes either end of the grout, disassemble pipeline ready for cleaning. 9, sealing: when there is no water leakage inspection, remove the filling head, with cement mortar and other materials will 孔补平 trowel. 10 Note: (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, King and other fast plugging 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. 11, the corresponding construction supervision procedures: (1), we send someone to carry out 24 hours tracking, inspection, supervision, from materials, mechanical approach to find the water leak points of the selected hole, then drill grouting, the final clean the whole process involved in repairing surface inspection. (2), in materials, construction machinery, please approach the Commissioner for review; (3), in the arrangement of water leakage point selection and hole position, please review supervision; (4), at the time of drilling and grouting please Supervision to supervise and inspect the whole process; (5), in the mouth and the slot before removing grout repair prior notice supervision, supervision during the entire process of repairing your supervision cesspool waterproof plugging
