Well-sealing-free pneumatic dewatering device in foundation pit and foundation pit construction method
The well-sealing-free pneumatic dewatering device in the foundation pit comprises a first water storage cavity, a plurality of one-way water inlet valves are arranged on one side wall of the first water storage cavity, an air inlet and outlet pipe and a water outlet pipe are sequentially arranged on the other side wall, away from the one-way water inlet valves, of the first water storage cavity from top to bottom, and one end of the air inlet and outlet pipe and one end of the water outlet pipe extend into the first water storage cavity; the gas detection assembly comprises a first pipeline and a second pipeline, one end of the first pipeline and one end of the second pipeline are detachably communicated with the other end of the gas inlet and outlet pipe, a gas flowmeter is arranged on the first pipeline, and the other end of the second pipeline is communicated with a gas supply device; and valves are arranged on the first pipeline, the second pipeline and the water outlet pipe. The method has the beneficial effects that on the premise that concrete hardening is not affected and holes are not reserved in the bottom plate, concrete can be poured at a time, well shut-in work is omitted, the construction efficiency is improved, and the construction quality of the bottom plate can be guaranteed.
本发明公开了一种基坑内免封井气动降水装置，包括第一储水腔，其一侧壁设有多个单向进水阀，所述第一储水腔远离单向进水阀的另一侧壁上由上至下依次设有进排气管、出水管，所述进排气管和出水管的一端均伸入所述第一储水腔内；气体检测组件，其包括第一管道、第二管道，所述第一管道和所述第二管道的一端均与所述进排气管的另一端可拆卸连通，所述第一管道上设有气体流量计，所述第二管道的另一端与一供气装置连通；其中，所述第一管道、所述第二管道、所述出水管上均设有阀门。本发明具有的有益效果是，能够在不影响混凝土硬化、不在底板留洞的前提下，一次性浇筑混凝土、免去了封井工作，提高了施工效率，能够保证底板的施工质量。
