Zhenjiang trap plugging undertake various professional bridge expansion joints, pool joints, construction joints, construction joints, cross joints, cracks off, settlement plugging leakage of water. Jiangsu large plugging company to undertake professional: cesspool plugging, plugging basement, basement garage construction joints, expansion joints seepage plugging plugging large dock, wall construction joints, cracks off, floor joints leak water plugging. Plugging tunnels, subway project settlement joint, joints, construction joints, cracks off water leakage plugging. Cable channel plugging, slim pit construction joints, cracks off leak water, with water pressure plugging works. Cooling tower plugging, cooling tower corrosion plugging project cycle path. Caisson, pump house, dam tunnel, take the drainage project, a large area of ??water leakage plugging. 3 Quality Control waterproofing membrane waterproofing membrane of diverse types of materials such as bitumen membrane, polymer modified bitumen membrane plugging and synthetic polymer waterproofing membrane and so on. Construction techniques commonly used hot-melt, hot air welding method, self-adhesive, cold glue, mechanical fixation, embedding method and so on. 4 sealed waterproof construction materials quality control points sealing materials commonly used are synthetic polymer modified asphalt and sealed waterproof material into two categories; construction methods vary according to different materials, sub-cooling and hot filling inlay and French. To ensure the quality of construction should be used in the construction equipment, ingredients and stir a few key bond test and filling them with backing material control, and supervise construction operation control. 5 rigid waterproof layer construction quality control points include rigid waterproof layer, waterproof layer of cement mortar, construction blocks rigid waterproof layer and waterproof concrete fine aggregate concrete waterproof layer. Rigid waterproof roofing structure layer should be for the whole cast reinforced concrete, the slope should be 2% to 3%, and the structure should be used to find the slope. And with gable roof parapet and prominent junction structure rigid waterproof layer, flexible seal the deal should be done. Non-waterproof layer buried pipelines. Rigid waterproof layer on the uneven foundation settlement, temperature changes, the structure is very sensitive to vibration and other factors, so the foundation treatment demanding. 6 underground engineering Concrete Construction Quality Control Waterproof waterproof concrete in aggressive media, impermeability grade of not less than P8; concrete pad waterproof concrete structure, its compressive strength rating of not less than C15. Thickness of not less than l00mm. Structural waterproofing concrete structure thickness of not less than 250mm, the crack width shall not be greater than 0.2mm, the positive side of reinforced protective layer thickness of not less than 50m. Concrete pouring water should be continuous, leaving construction joints should be less. In order to strengthen the role of the construction sealing joints between the basement floor and foundation walls, on the floor away from the 300 "- Wall template under 500mm at the facades add a 3mm thick, 300me wide ring around the plate through a water stop. Fill the inside of the mouth with foam inserts to prevent leakage of plasma. According to the structural design, pouring with reasonable settings and Deformation. using a large volume of concreting technology to prevent temperature difference caused by hydration heat generated temperature cracks. 7 pay attention to water projects product protection (1) waterproof layer construction should be finished early next construction process, the interval should not be too long, waterproof layer to prevent material damage. (2) waterproof membrane construction should be careful to protect the waterproof layer has been done to prevent all kinds of construction equipment and other debris to damage the waterproof layer; construction workers are not allowed to wear shoes with nails walk on the waterproofing membrane (3) waterproof coating layer construction workers to avoid walking on the completion of construction of the coating. avoid spikes and sharp hard object scratched coating after drying and curing waterproof coating, protective layer should be done to reduce unnecessary rework. through the roof of the pipe should be protected, floor drain, construction should fall-mouth, etc. take measures to maintain a smooth flow to prevent clogging.
