Precipitation well bottom plate penetrating sealing device and construction method thereof
The invention discloses a dewatering well bottom plate penetrating sealing device and a construction method thereof. A dewatering well is arranged in a soil body at the bottom of a foundation pit, and a well pipe is arranged in the dewatering well; comprising a casing pipe, the lower end of the casing pipe extends into the dewatering well and is arranged at the top of a well pipe in a sleeving mode, a bottom plate is arranged in the casing pipe and abuts against the top of the well pipe, a through hole used for pumping water is formed in the middle of the bottom plate, and a plugging piece is arranged at the position of the through hole. A water stop plate and a plugging plate are arranged at the top of the sleeve; the water stop plate is fixedly connected to the outer side wall of the sleeve in the annular direction, and the top face of the water stop plate is flush with the top face of the sleeve. The plugging plate is plugged at the upper end opening of the sleeve, and the outer edge of the plugging plate is fixedly connected with the water stop plate; a concrete layer is filled in the sleeve and between the plugging plate and the bottom plate; micro-expansive concrete is poured on the top of the plugging plate so as to solve the plugging problem of the precipitation well.
本发明公开了一种降水井穿底板封闭装置及其施工方法，降水井设置在基坑底部的土体中，在降水井中设置有井管；包括有套管，所述套管下端伸入降水井中、并套设在井管顶部，所述套管内设置有底板，所述底板抵在井管顶部，在底板中间开设有用于抽水的通孔，所述通孔处设置有封堵件；所述套管顶部设置有止水板和封堵板；所述止水板沿环向固定连接在套管的外侧壁上，且止水板的顶面与套管顶面平齐；所述封堵板封堵在套管的上端口处，且封堵板的外边缘与止水板之间固定连接；所述套管内、位于封堵板与底板之间填充有混凝土层；所述封堵板的顶部浇筑有微膨胀混凝土，以解决降水井的封堵问题。
