Guilin waterproofing and leak repair. Guilin Waterproofing Company has several optimized technologies for underground engineering waterproofing. The problem of underground leakage has always been a thorny issue in underground waterproofing projects. The use of new materials, new processes, and new methods plays a key role in improving underground waterproofing effects. This article introduces the detailed waterproofing technology of a certain subway station. The various construction methods and measures described have been used in subway station projects with high waterproofing requirements. In the project, a combination of rigidity and softness, and a combination of anti-drainage and drainage methods were adopted, focusing on the introduction. Several effective methods were proposed to deal with the details of external waterproofing, which achieved good results and provided a reference for improving the construction quality of basement external waterproofing. Keywords Underground engineering expansion joint waterproofing treatment As people's awareness of ecological environment protection continues to increase, the widespread application of underground environmental protection projects has attracted more and more attention. Street tunnels, underground parking lots, high-rise building basements, subway projects and other underground projects There are more and more constructions. The use of new materials, new processes, and new methods plays a key role in improving underground waterproofing effects, ensuring equipment safety and appearance, and extending structural life. The various construction methods and measures described in this article have been used in subway station projects with high waterproofing requirements, and have achieved good results. Project Overview: A certain subway station project mainly focuses on structural self-waterproofing, and the external waterproofing method is supplemented by all-inclusive waterproofing. It is a waterproof structure composed of a flexible waterproof layer and a waterproof reinforced concrete lining, with a waterproof area of approximately 100,000 square meters. The waterproof standard of the main structure of the station is Level 1, which means that the structure does not leak, and there must be no wet stains on the surface of the structure. The waterproof standard of the entrance and exit passages is Level 2, that is, the structure does not leak, and a small amount of occasional wet stains are allowed on the surface of the structure. The structural roof adopts a thick non-tar polyurethane coating waterproof layer, and the bottom plate and vertical walls adopt a thick self-adhesive elastomer asphalt membrane waterproof layer. The waterproof layer is constructed using the external waterproofing and internal sticking method. The vertical wall is protected by a rolled waterproof layer of polyurethane film with a thickness of 1m polyethylene foam board adhered to the surface as an isolation layer. Waterproof design principles and standards my country's "Subway Design Code" [], "Code for Construction and Acceptance of Underground Railway Projects" [] and "Technical Code for Waterproofing of Underground Engineering" [] have made special provisions on the waterproofing of subway engineering structures, stipulating the following waterproofing of underground projects The design should follow the principles of giving priority to prevention, combining prevention and drainage, adapting measures to local conditions, and comprehensive management. The design of waterproofing projects should follow the principles of combining prevention and drainage and fortification on the water surface, and adopt measures such as multi-channel fortification, composite waterproofing, and node sealing. Optimization plan for waterproof construction. Pretreatment of the base layer for waterproof layer construction. Since the building envelope of this project uses interlocking manually dug piles and three horizontal steel pipe supports as the supporting structure, the waterproof layer is constructed using the external defense and internal sticking method, that is to say, Before tying the steel bars of the base plate and wall panels, the external waterproofing membrane must be pasted on the backfill concrete layer between the base plate cushion and the piles. Self-adhesive membranes are cold-adhesive membranes. Like most waterproof materials, the construction conditions require that the base moisture content of the concrete base should not be greater than %. It is relatively easy to build the roof of the station or the base surface of the external waterproofing type, but there are certain difficulties in the construction base of the base plate of the station and the side walls of the laminated structure. Due to the excavation of the foundation pit and the construction of steel supports, the station's retaining piles will be dislocated and deformed, causing cracks to occur between the originally interlocking bored piles. Groundwater can easily seep into the foundation pit along the cracks. If no inter-pile treatment or inter-pile sealing treatment is performed at this time, and the concrete backfill between piles is continued as usual, the seepage will seep along the edges of the piles and the weakest points of the backfill concrete, resulting in seepage everywhere on the base surface, making it worse. Difficult to handle. Adopting organized drainage treatment methods can solve this embarrassing situation of blind blocking causing water seepage to spread everywhere. The specific method is to use cut pipe segments or bamboo slices to make a water diversion channel along the concave position of the piles (see picture) before constructing the leveling layer between the piles, and guide the seepage water between the piles to the surrounding base of the foundation pit. Organized drainage blind ditch Heji Company focuses on difficult leakage, water seepage and waterproofing problems in various buildings, and provides technical support and complete and scientific construction plans. It has a professional construction team of waterproof plugging, reinforcement and repair, and specializes in providing Guilin waterproofing, leak repair, roof Leak repair, house leak repair, roof leak repair, basement waterproofing, exterior wall leak repair and other services, introducing advanced foreign pressure-proof, anti-seepage and anti-vibration waterproofing and leak-proofing technology, using imported high-tech nano-micromolecule waterproof materials, precision formulation and science The new technology of pressure-reducing grouting is used to professionally manage various difficult leakage plugging projects.
