Embodiment
[0017] A construction method for pressure-reducing leak plugging of a post-pouring belt under high pressure water, using stainless steel pipe 1, pumping hose 2, flange plate 11, water pump, etc. to drain and depressurize the leakage of post-pouring belt A, and then place the stainless steel pipe 1. Buried directly under the post-casting belt A of the concrete, and sealed the concrete with plugging points and pressure-reducing points.
[0018] Specific steps are as follows:
[0019] 1. At the post-casting belt A where leakage occurs, drill the operation well B with a width of 100mm on each side, drill the inner flat angle on both sides to the position of the structural steel bar, and bury a 50mm diameter and one end at the position where the high-pressure water head occurs. A stainless steel pipe 1 with a flange 11, the surroundings of the stainless steel pipe 1 are tightly sealed with concrete, and if necessary, a waterproof rubber ring is used to seal the stainless steel pipe...

The invention discloses a depressurization and leaking stoppage construction method for a high-confined-water post-cast strip. According to the method, drainage and depressurization are carried out on a leaking position of the post-cast strip (A) by utilizing a stainless steel tube (1), a water pumping hose (2), a flange plate (11), a water pump and the like, and then the stainless steel tube (1) is directly buried in the position below the concrete post-cast strip (A) so as to seal concrete with a leaking stoppage point and a depressurization point. Compared with the prior art, the method has the advantages of being simple in process and high in construction speed; an embedded part is fixed reliably, and especially for regions with relatively high underground water level and water pressure, the design and construction specification requirements can be met completely by adopting the construction method.
Description
technical field [0001] The invention belongs to the field of construction, and relates to the technical field of leakage and decompression of basement floors in high-pressure water areas, in particular to a construction method for depressurization and plugging of post-casting belts with high pressure water. Background technique [0002] In the construction of the concrete structure of the house building, the post-pouring belt construction of the basement is the key point of construction. In the construction process, there will be different degrees of leakage, especially in areas with a high groundwater level and high water pressure. Due to the water pressure problem, it caused great trouble to the plugging construction, and the quality of the plugging was not easy to guarantee and caused many reworks. Once the method is not proper, not only the leakage problem cannot be solved, but also the construction period will be extended indefinitely. Especially in areas with a high g...
