Importance of plugging: underground works mainly include basements of industrial and civil buildings, underground garages, underground tunnels, underground tunnels, etc. In underground engineering, it is common for water leakage to occur in projects under construction or completed due to factors such as poor design, improper structural treatment, poor material selection, poor construction quality, foundation subsidence, and changes in hydrogeology near the project caused by human or natural disasters. If it is not treated in time, the project progress, use function and even the safety of the project structure will be affected.
Our company's professional leak stoppage technology: "polymer grouting waterproof leak stoppage technology". Our company adopts the technology developed by professional waterproof and anti-corrosion material manufacturers and several important scientific research institutions for many years. It uses a variety of imported chemical materials, and according to the size of the construction water flow pressure, it is made into a liquid with almost the same viscosity as water. With good permeability, it can be injected into 0.1mm concrete slit, and quickly agglomerate under water pressure and very humid environment. The setting time can be accurately controlled within a few seconds or several minutes according to the proportion, and can be quickly condensed under the condition of high water speed, pressure and water flow. Good impermeability, water swelling after drying shrinkage, insoluble in water, kerosene, gasoline and other agricultural production system solvents, resistant to acid, alkali, bacteria, and not affected by atmospheric conditions, with certain strength, elasticity and pressure change, and guaranteed for use for more than 10 years. With strong tensile strength, the cracks that have been plugged will not leak if normal settlement or dislocation cracks occur in the future.
The specific construction method of plugging: the back water back pressure plugging method includes grouting method and caulking method. First, chisel a week around the junction between the leakage and the cement, chisel the cement into a 3.5 * 4.5 U-shaped joint and each leak at the plane leakage into a U-shaped joint, clean the surface of the leakage layer, and then use quick setting water stop materials to bury pipes, draw pipes, and divert water for flow reduction. The groove does not need to be filled at a time, so as to leave room for caulking. A bamboo joint (grouting nozzle) is set every certain distance, After the quick setting material reaches a certain strength, the elastic plugging slurry can be poured into the bamboo joint by back pressure until the deformation joint no longer flows out of water. The rapid setting material will expand in case of water, and then the upper part of the concave handle of the deformation joint of the water stop will be filled with castable to compact the surface layer. The combination of material waterproof and structural waterproof, that is, the combination of rigid and flexible long-term waterproof plugging technology.
Specific construction process of plugging:
1. The joint shall be chiseled according to the quantities of * * * required by Party A.
2. Clean the leaking parts and chisel the leaking joints into U-shaped joints.
3. Milling the leakage joint, embedding the bamboo joint, cleaning the leakage joint, filling the plugging material, installing the suction pipe and bamboo joint (grouting nozzle).
4. Diversion, decompression, reduction of water flow, control of water leakage points, change large water flow into small water flow, and make small water flow out of the installed diversion pipe.
5. Ingredients: several reagents are mixed into two groups of mixed slurry, and the setting time of ingredients is determined according to the amount of water leakage.
6. Back pressure grouting: the pressure of grouting must be greater than the pressure of water leakage, so that the water can be pushed back and infiltrated into the capillary joints of the leaking rock. When encountering water, it will expand and set quickly to achieve long-term deep water stop effect.
7. Dig out the bamboo knots (or not) and fill them directly with plugging materials.
8. After surface treatment and no leakage through self inspection, the surface slurry shall be scraped flat.
With advanced technology, scientific management and excellent construction team, our company strives to win with quality and keep improving. We are willing to establish various forms of cooperation with friends from all walks of life.
