Foundation pit dewatering well plugging device and foundation pit dewatering well plugging method
The invention relates to the field of buildings, in particular to a foundation pit dewatering well plugging device and method.The foundation pit dewatering well plugging device comprises a well mouth sleeve, an outer water stop flange ring, an inner water stop flange ring and a plugging plate, and the well mouth sleeve is arranged in a structural bottom plate at a well mouth of a dewatering well; the outer water stop flange ring is connected to the outer wall of the wellhead sleeve; the inner water stop flange ring is connected with the inner wall of the wellhead sleeve, and an operation hole and a plurality of flange threaded holes formed along the operation hole are formed in the middle of the inner water stop flange ring. The blocking plate can be connected with the inner water stop flange ring so as to block the operation hole. The method comprises the steps that the foundation pit dewatering well plugging device is installed; the water level in the dewatering well is pumped to a set height; the dewatering well is sequentially filled with gravel and concrete till the concrete is located at the inner water stop flange ring; and the plugging plate is connected with the inner water stop flange ring, and concrete continues to be poured to the opening of the dewatering well. The operation is convenient, the plugging time can be shortened, and the plugging effect is improved.
本申请涉及建筑领域，具体涉及一种基坑降水井封堵装置及基坑降水井封堵方法，其中，装置包括井口套筒、外止水法兰环、内止水法兰环和封堵板，井口套筒设置在降水井的井口处的结构底板中；外止水法兰环连接在井口套筒的外壁上；内止水法兰环与井口套筒内壁连接，并在自身中部形成有操作孔和沿操作孔布置的多个法兰螺纹孔；封堵板能够与内止水法兰环连接以将操作孔封堵。方法包括：安装基坑降水井封堵装置；将降水井内的水位抽取到设定高度；向降水井内顺次填充砂砾和混凝土至混凝土处于内止水法兰环处；将封堵板与内止水法兰环连接，并向降水井井口继续浇浇筑混凝土。本申请操作方便，能够减少封堵时间，提高封堵效果。
