Problems solved by technology

[0002] During the construction of the base plate, if a dewatering well is set in the foundation pit, the dewatering well will be retained, used for dewatering, and the dewatering well will be closed later, but there will be a risk of water seeping from the dewatering well in the later stage; if the dewatering well is not set in the foundation pit, generally A post-pouring belt will be installed, water will overflow from the post-pouring belt, and the post-pouring belt will become a great hidden danger of water leakage in the future

Abstract

The invention discloses a base plate pressure reducing device which comprises a pressure reducing valve and a water filtering pipeline. The water filtering pipeline is composed of a columnar pipeline, a conical-barrel-shaped water inlet and a water filtering screen covering the conical-barrel-shaped water inlet; a lower end opening of the columnar pipeline is communicated with the conical top of the conical-barrel-shaped water inlet in a butting mode; an upper end opening of the columnar pipeline is communicated with a water inlet of the pressure reducing valve in a threaded butting mode; a ring of an annular water stop plate is arranged on the outer wall of the columnar pipeline, and the plate surface of the annular water stop plate is perpendicular to the axis of the columnar pipeline. According to the base plate pressure reducing device, water draining and pressure reducing can be performed in real time in the foundation pit construction process, the sealing property is good, and a better application prospect is achieved.

Description

technical field [0001] The invention relates to a bottom plate construction device, in particular to a construction device for bottom plate decompression. Background technique [0002] During the construction of the base plate, if a dewatering well is set in the foundation pit, the dewatering well will be retained, used for dewatering, and the dewatering well will be closed later, but there will be a risk of water seeping from the dewatering well in the later stage; if the dewatering well is not set in the foundation pit, generally A post-pouring belt will be installed, water will overflow from the post-pouring belt, and the post-pouring belt will become a great hidden danger of water leakage in the future. Contents of the invention [0003] Purpose of the invention: to provide a device for decompressing the foundation pit floor during construction. [0004] Technical solution: The floor decompression device according to the present invention includes a pressure reducing ...
