Minshan Yaju basement seepage repair
Problem: The corner of the staircase at the entrance of the pump room is seriously leaking at the beginning and needs to be excavated for maintenance.
Basement leaking form:
The form of water leakage is related to geological conditions, structural conditions, and construction season, and mainly reflects the following conditions.
(A) gushing water
When the groundwater pressure is high, the leaking water flow is large, sometimes it can't be blocked, and it is constantly flowing like a spring.
Leaks in the basement sometimes flow out along cracks in the concrete of the building structure, creating a subsurface flow.
The leak in the basement leaks out at a number of places on the surface of the structural concrete. The degree of leakage is different. The larger one wipes it with a dry cloth, and then you can see multiple small drops of water coming out. ; Or I saw that the wet stains will never dry, and will get wetter after half a day or hours. In some basements, there may be intermittent leaks, which may be affected by fluctuations in groundwater pressure. Sometimes the leaks leak or seep, and sometimes the mattress seepage disappears.
The specific standards of the design are decomposed into each process, and the quality points are clarified. Supervising the construction unit to achieve the standards is meticulous and careful to achieve the effect of quality assurance. The waterproof construction of important projects should be supervised by the station.
Since the excavation of the foundation pit, if there is water leakage in the foundation, the anchor and spray water treatment method is adopted to close the section and infiltrate the water to create conditions for construction.
Pouring and continuous operation with self-waterproof concrete ensure that the project quality exceeds the design requirements within the index by 10% -20%, and achieves high-quality projects.
Master the changes and laws of groundwater in the project area, and make the structure self-waterproof for the purpose. Design reasonable anti-seepage indicators, based on the actual construction quality, to achieve a high standard of drip-free construction and risk-free completion.
