Leakage repair of expansion joint of belt underground corridor Maintenance and plugging work is particularly important for the problems of wall cracking of cable trench corridor and water leakage and seepage of ground expansion joint. If these problems are not handled in time, they may lead to cable damage and even safety accidents. Therefore, it is very important to take appropriate maintenance and plugging measures. First, we need to repair the wall cracks of the cable trench gallery. The wall cracking may be caused by aging materials, improper construction or foundation settlement. In order to effectively repair the cracked wall, we can take the following measures: 1. Thoroughly clean the cracked wall

Treatment method for water seepage and leakage of pool cracks The treatment method for water seepage and leakage of pool cracks is as follows: 1. Quick leak stoppage method: quickly stick a water stop pin on the place where the surface leaks, and then use cement to smooth it. 2. Grouting repair method: first cut the water seepage surface with a blade, clean it up, and then repair it with quick setting cement slurry from one end to the other. Seal the groove after confirming that there is no problem, and then stick the American paper to the groove during the sealing process. Because the cement has the characteristics of thermal expansion and cold contraction, directly pasting ceramic tiles will lead to the loosening of ceramic tiles, so use textured paper to paste a layer of paper before construction. After construction

What kind of material should be used to fill the wall expansion joints of the waterworks? The construction sequence of waterproof and plugging should be to plug the big leaks first, and then the small leaks; First high, then low; First the wall body, then the bottom plate. The grouting technology can be generally divided into the following steps: 1. On site inquiry, determine the detailed repair plan. 2. Grooving along the crack, groove type "V", groove width X depth is 2-3X2-3cm (this process is applicable to crack leak repair). 3. Determine the planning and hole arrangement plan of grouting holes. The orientation of the grouting hole shall be such that the bottom of the hole intersects with the leakage crack hole, and it shall be selected at the leakage amount. 4. Joint sealing and consolidation grouting nozzle. 5. Check the pressure of pressurized water or air

Water leakage and plugging method for tunnel expansion joints Grouting machine, electric drill, patch board, wrench, pliers, screwdriver, water stop needle, high-pressure pipe, hammer, chisel, ladder, etc. are used to repair the leakage of basement joint joints, and common tools used in waterproof and plugging construction of basement. 2. Prepare polyurethane grouting fluid, plugging agent, diluent, engine oil and other materials, which are commonly used in waterproofing and plugging. 2、 Hole drilling and grouting 1. The soft base reinforcement of the base at the leaking part is relatively poor, which is called the soft base. The conventional treatment scheme of the soft base is to clean the soft base with a chisel. The height and width of the soft base are uncertain, as long as it is cleaned to the harder base, and then

Grouting and plugging of expansion joints in cable tunnels Leakage water plugging at civil air defense junction Grouting and plugging of expansion joints in cable tunnels refers to grouting of expansion joints in cable tunnels to prevent water leakage. The expansion joints are designed to adapt to the expansion deformation of the tunnel structure, but they are also easy to become water leaks. First, the sundries and accumulated water on both sides of the expansion joint need to be cleaned. Then, apply sealant evenly on both sides of the expansion joint to ensure that the sealant can fully fill the gap of the expansion joint. Next, use special grouting equipment to inject grouting materials into the expansion joint to ensure that the grouting materials fill the entire expansion joint. Waiting for grouting material

How to deal with the leakage blocking of the construction joint of the biological reaction pool structure joint 1. Chemical grouting can be used to remedy the fracture of the bottom expansion joint waterstop by chemical grouting plus removable waterstop. Because the chemical grouting material has good bonding performance with concrete, it has good elasticity and water swelling property after forming solid. Before grouting, the polystyrene board, cracked waterstop and other sundries in the original expansion joint shall be manually removed with a steel file, and then the concrete surface within a 500mm wide range of the part shall be cleaned to make it clean, flat and smooth. Clean the seam and other sundries in the seam

Maintenance method for waterproof and plugging of settlement deformation joints of biological pool wall structures The reasons for cracking and seepage of concrete in chemical plant pool caused by crack plugging of chemical plant pool are complex, involving many factors, which can be roughly divided into two categories: cracks caused by load and cracks caused by deformation. For drainage structures such as pools, most of them are underground or semi underground open structures, with high waterproof and impermeable requirements, and the generation of cracks must be controlled in design. The cracks are mainly caused by temperature difference and concrete shrinkage. Solution 1, surface cleaning: clean the concrete surface about 3cm around the crack, find out the crack location and water

How to deal with the serious water seepage in the basement? 1. If there is water seepage at the wall root, the leaking position of the wall root needs to be treated. Cement mortar needs to be used to build the wall of the basement to ensure the mortar's fullness, so that water will not leak from the brick joints. 2. At the same time, the dust and garbage on the inside and outside of the exterior wall shall be cleaned up before plastering, so as to ensure that the root can achieve a compact function during plastering. 3. After that, the inner and outer sides of the wall should be waterproof. You can choose waterproof mortar. When you apply waterproof mortar, you can

How to deal with the leakage of the deformation joint of the wastewater pool How to deal with the leakage of the expansion joint of the waterstop of the wastewater pool Our philosophy: persistence, * * *, * * *, focus. I firmly believe that with my own experience and the team of * * *, we can conscientiously provide customers with waterproof solutions to help others achieve their own goals, and our goals will certainly become a reality! How to deal with leakage at the plugging price is also a combination of three schemes: plugging/drainage/plugging and drainage, which can be divided into traditional plugging methods and chemical grouting methods. 1. The traditional method of plugging is to chisel the crack or leakage to plug the surface leakage, but the result is often to plug here, then
