Drainage structure and drainage method for building foundation pit
The invention relates to a drainage structure and a drainage method for a building foundation pit. The problem that the drainage capacity of a dewatering well is reduced is solved. The drainage structure comprises the dewatering well formed in a soil layer and further comprises a mounting base, wherein the mounting base is provided with a dewatering pipe, an outer pipe sleeve and an inner pipe sleeve; the mounting base is provided with a supporting column; a guide ring is arranged at the top of the supporting column and provided with an inlet and outlet opening; a connecting hole used for communicating with the inlet and outlet opening in the same set is formed in the guide ring; a connecting rope is slidably arranged in the connecting hole; a mounting ring is arranged between the outer pipe sleeve and the inner pipe sleeve in an up-down sliding mode and comprises a first ring body and a second ring body; a piece of cylindrical filter cloth is arranged at the top of the first ring bodyand folded inwards to cover the top of the guide ring; and the other end of the filter cloth is fixed to the top of the second ring body. The drainage structure further comprises a sealing plate; a pressing rod is arranged at the bottom of the sealing plate; the bottom of the pressing rod abuts against the top of the mounting ring; and when the bottom of the first ring body abuts against the topof the mounting base, the top of the second ring body abuts against the bottom of the guide ring. The drainage structure has the effect of improving the drainage capacity of the dewatering well.
