Project Overview The project Vanke new elm mansion located in Shenyang, Shenyang Hunnan Jinyang Street, at the junction of the voyage west Liaoning Province, 3.2 is the sewage treatment works, 5146.17 m long underground pipeline full. Second, prepare a construction, materials used: SL-669310 type polymer grout mixture (flexible elastic material). 2. All materials must have certification, inspection reports, Zhunyongzheng. Re-examination of the witness as required sampling, qualified before use. 3, the main tools: drill, high pressure pump, hammer. 4, after the rain the next well-organized construction, water works by BJ15-19-97 "waterproof construction engineering point of order" in construction. 5, the organization leading group. Third, the construction process 1, leaks rain acceptance drill grouting 2, and so on through the rain under the weather or heavy rain, sewer leakage points (must have water). 3-point range in the leak repair center using the Hammers were sewn, and clean up after the seam repaired. 4, using a special packer inserted within the gap, and then use high-pressure grouting machine SL-669310 type polymer grout mixture (flexible elastic material) pressed into the leaks. 5, SL-669310 type polymer grout mixture (flexible elastic material) water resistance ranges where there is water in the case of a second sealing agent will form a water-blocking film. 6. Finally, quick-setting material with waterproof seal surface. Fourth, safe, civilized construction measures 1, before construction, to address security protection facilities for inspection. To ensure that the construction work can be carried out after the complete and effective. 2, after the completion of each job to do team work completed, materials to make clear the site, the use of the tool in a timely manner or in designated storage location. A sewer leakage control program, Project Overview sewer leakage control program, mainly for the use of sewage pipes and cement pipes, sewers after completion of the installation, due to uneven foundation settlement and displacement, the cross seams (joints) pipe joints shift, moving parts of a large amount of leakage, so the next step of construction can not be, it is necessary to take immediate measures to quickly and effectively plugging water, so that the building sewers achieve watertight construction requirements to meet the next construction and use requirements. Second, the programming based on a national standard GBJ108-87 "underground works waterproof technical specifications" two national standards GBJ208-83 "underground works waterproof construction and acceptance of" 3, waterproof plugging project costing 4, "waterproofing Atlas "5, the existing water projects nationwide fixed compilation 6, China Association for Engineering Construction Standardization standard CECS117: 2000" accumulator design objects and structures Deformation order "7, national building materials industry standard JC483-92" polysulfide sealant "8, the Party concerned Three technical quality and construction requirements, expansion joints (Deformation) a leakage control program, expansion joints for leaks in underground engineering analysis joints (Deformation) is easy to produce special parts leaking, leaking main reasons are the following generation areas: (1) underground engineering deformation is too large, exceeding the allowable deformation range, mainly based on thermal expansion and contraction and differential settlement. (2) rapid displacement basement Deformation generated in the construction process, causing damage to the rubber water stop. (3) has not reached due to dense extent pouring concrete, resulting in a loose, doghole, cellular and other phenomena, forming a leakage of water channels. (4) Rubber Sealing incomplete curing, resulting in aging fracture after a long time, or in the construction of drill rod chisel is bad. Once the leak joints that show the entire water stop failure, it must conduct a comprehensive whole perimeter seam leakage control to be effective. 2, waterproof plugging leaks cause analysis program based on the above, this program uses the first waterproof plugging Grouting, after using a flexible polymer sealant to protect the final rigid protection measures plugging specific programs shown below: 1, grouting plugging Wang 2, PE foam strip (double) 3, rapid plugging agent mortar (thickness 40 ~ 50mm) 4, PG321 two-component polysulfide (thickness 20mm) 5, 6 compression sealants, expansion joints - side of the concrete waterproof plugging program are as follows: (1) removal of the grass-roots: the joints and remove impurities in the original materials to the required depth (typically 7 ~ 10cm deep), rinse with water. (2) fixed grouting channel and grouting pipe: mixing over 32.5 ordinary portland cement grouting channel -PE fixed foam strips with rapid plugging agent (liquid, powder may be), PE foam strip at a fixed time, each separated by a grouting pipe buried about 50cm. Grouting tube with? 10 ~ 13mm of pressure rubber hoses, both as a water pipe in the pipe and as grouting works. (3) grouting plugging: Start Note polymer grouting material from the bottom - plugging Wang grouting, grouting pressure control between 0.3 ~ 0.5MPa, to be next to a hole grouting stop oozing slurry grouting close the valve, and then from another hole grouting, followed sequentially performed after grouting is completed until all leaks were observed, as there are some places you can add leakage from a hole grouting until recently no leakage so far. (4) cut grouting pipe: 24h after grouting confirm no leakage under the circumstances, cut off all grouting pipe, with a blowtorch drying interface. (5) to clean up the interface: Use a wire brush to clean the skin of impurities and miscellaneous debris generated due blowtorch baking. (6) Construction of a flexible material: 50 ~ 60mm thick PG321 construction component polysulfide sealant in the joints, T-posted outside width 300mm, 20mm thick two-component polysulfide sealant. (7) as a protective layer: After the polysulfide sealant cured sealant with compression as the last semi-rigid protective layer. Fourth, cracks leak governance programs and projects in accordance with the requirements of the actual situation of the Party, you first need to crack grouting waterproof plugging leakage area, then two-component polysulfide sealant for flexible sealing layer, compressive seal again agents rigid waterproof protective layer construction. Plus flexible waterproof rigid protective waterproof plugging program is based on a national "underground works waterproof technical specifications" of requirements.
