Jiangsu large plugging Engineering Co., Ltd. Haimen plugging plugging Hotline: 13961999789 plugging company to undertake the project in accordance with the actual situation, we first need to crack grouting waterproof plugging leakage area, then flexible waterproof layer, again fast block Drain Spirit rigid waterproof protective layer construction. Plus flexible waterproof rigid protective waterproof plugging program is based on a national "underground works waterproof technical specifications" of seeking performed. A waterproof sealing, structural reinforcement construction procedures are as follows: 1, first a deep chisel construction joints 70mm, width 60mm of "V" type joints, clean water rinse. 2, the fixed channel and grouting grouting pipes fixed quickly plugging Ling grouting channel strip PE foam, PE foam strip at a fixed, every one about 50cm buried pipe grouting, grouting tube with 10 ~ 13mm of pressure rubber hose, the tube has been used as water pipes and as grouting works. 3, sealing and grouting plugging polysulfide flexible waterproof seal from the side of the start of construction of polymer injection grouting material - plugging Wang grouting, grouting pressure control between 0.3 ~ 0.5MPa, to be next to a grouting holes can stop take slurry grouting, and close the valve and then plugging the hole grouting from another, followed by the order, until all leaks observed grouting is completed, there are still some places such as leakage from the nearest A supplementary grouting hole until no leakage so far. Cut pipe before making PG321 component polysulfide sealant construction. 4, rigid protective layer construction when grouting waterproof plugging cracks will not produce leaks, with rapid plugging Ling made two rigid waterproof protective layer, a large area of ??leakage control program, the surface layer method: applied to the structure The large area of ??leakage of water treatment. Under normal circumstances, a large area of ??the basement seepage water treatment can not be carried out the positive side, only in the dorsal surface treatment, it is in pre-construction, drainage should be cited, in order to prevent new surface layer is made of waterproof pressurized flush bad. Surface layer of concrete practice of law: Choose the amount of leakage centralized location, open hole borehole water flow from the catheter. According to the amount of the size of the leak can be in one or multiple water pipe, can not find the leakage point, in the lower part of the wall water pipe. Then watertight material requirements in accordance with the site, a large area smear polymer cement mortar waterproof need stratification TROWELING, order plain water slurry - waterproof mortar - Waterproof prime pulp, last dialed tube shutoff. For concrete slight seepage, plugging Ling available compression applied in the concrete surface, with a scraper construction, general construction of 2 to 3 times, but not until the water film so far. For obvious leakage of water holes and cracks, holes and cracks leakage by water treatment method, one by one waterproofing. For the structure of the surface of the concrete basement, water pressure in the smaller less severe slow leakage of water (such as sweating, Yin wet, etc.) can be anti-scratch coating on the back surface of the water leakage grams, so that the surface layer of impermeable cover layer impermeable to play the role. Specific practices: the primary surface treatment is smooth, rugged place filled with cement mortar, flatten trowel, while removing the primary surface dust, oil, etc., in order to facilitate the waterproof layer bonded firmly. After completion of the above work and pass the inspection, you can use anti-leakage grams construction. 2, grouting method: In case of a large area basement water leakage, grouting method may also be treated, can be arranged according to the grouting holes in the structure of water leakage case, the distribution into a plum-shaped, triangular or a shape, and then grouting treatment to form a water curtain in the internal structure. In addition, also the use of "closed surface grouting" approach, which is to water down the tube, and then a large area with rapid plugging Ling plaster, to be waterproof coating strength to meet the requirements, from the water pipe as Grouting. Jiangsu large waterproof plugging company is waterproof plugging technology development, research and construction in one integrated company with 40 years of construction experience, in recent years, the introduction of foreign advanced technology waterproof plugging, high pressure grouting equipment, continuous perfect waterproof plugging construction technology, and efficient block technological innovation, professional management of various underground leakage, especially for mass concrete crack leakage, tunneling, leakage plugging settlement expansion joints, has many years of successful experience in the maintenance treatment, fully equipped with tough waterproof plugging ability is close to plugging your experts! Construction performance throughout the country.
