Description

Technical Field

[0001] The utility model relates to the technical field of a post-cast strip pre-reserved pumping and drainage device, in particular to a post-cast strip pre-reserved pumping and drainage device. Background Art

[0002] The post-cast joint is a temporary construction joint left at the corresponding position of the foundation slab in accordance with the design or construction specifications to prevent harmful cracks that may be caused by uneven shrinkage or settlement of the cast-in-place reinforced concrete structure during construction. There is abundant groundwater in coastal and riverside areas. When constructing basements in such areas, there will be hidden dangers of foundation cushion leakage, which can easily cause water accumulation in the post-cast joint. The accumulated water needs to be drained during subsequent construction.

[0003] For example, a Chinese patent (publication number: CN210712963U) discloses a drainage structure for a post-cast strip of a basement floor, wherein a reinforcement layer and a cushion layer are sequentially arranged on the basement floor corresponding to the bottom of the post-cast strip from top to bottom, and the drainage structure comprises: holes in the reinforcement layer and the cushion layer arranged at the bottom of the post-cast strip; a casing which is open up and down and passes through the inside, the casing is inserted into the hole, the bottom end of the casing is against the bottom surface of the hole and the top end of the casing protrudes out of the top surface of the post-cast strip, and through holes are arranged at intervals on the side walls of the casing located below the reinforcement layer; a filling layer is sealed between the casing and the inner wall of the hole, and the top surface of the filling layer is lower than the top surface of the reinforcement layer; a water pump is arranged in the casing, and groundwater under the basement floor is pumped out by the water pump; after the water pump completes pumping out the groundwater under the basement floor, the sealing layer of the casing is densely filled, and there is no need to set up a template for casting to form a sump, so the construction process is simple, the operation is convenient and the efficiency is high.

[0004] However, the above-mentioned search patent still has some shortcomings. It uses a water pump to pump out the accumulated water in the post-cast strip.
