Well sealing structure of dewatering well and working method of well sealing structure
The invention discloses a precipitation well sealing structure and a working method thereof.The precipitation well sealing structure comprises a precipitation well arranged in a soil foundation, a cushion layer and a raft plate are sequentially laid on the surface of the soil foundation from bottom to top, a sleeve extending into the precipitation well is vertically arranged in the cushion layer and the raft plate in a penetrating mode, and the inner diameter of the sleeve is smaller than that of the precipitation well; at least two limiting grooves are evenly formed in the lower end face of the sleeve in the circumferential direction. A first hard pipe is movably arranged in the sleeve in a penetrating mode, the lower end of the first hard pipe penetrates out of the lower end of the sleeve and is in threaded connection with a second hard pipe, the lower end of the second hard pipe is connected with a submersible pump arranged in the dewatering well, at least two limiting rods are evenly distributed on the outer wall of the second hard pipe in the circumferential direction, and the limiting rods can be correspondingly matched with the limiting grooves. And after matching, the rotation of the second hard pipe around the axis and the degree of freedom of upward movement along the axis can be limited. According to the method, large damage to the raft plate structure can be reduced while the precipitation efficiency is not affected, and the well sealing effect can be improved by well sealing through concrete.
本发明公开了一种降水井封井结构及其工作方法，包括设置于土基中的降水井，土基表面由下至上依次铺设有垫层和筏板，垫层和筏板中竖向贯穿设置有伸入至降水井内的套筒，套筒的内径小于降水井的内径，套筒的下端面沿周向均布开设有至少两个限位凹槽；套筒内活动穿设有第一硬质管，第一硬质管的下端穿出套筒的下端且螺纹连接有第二硬质管，第二硬质管的下端连接有设于降水井内的潜水泵，第二硬质管的外壁沿周向均布设置有至少两个限位杆，限位杆能够与限位凹槽对应配合，配合后能够限制第二硬质管绕其轴线旋转和沿其轴线向上运动的自由度。本发明在不影响降水效率的同时，既能够降低对筏板结构产生大的破坏，又能够通过混凝土进行封井提高封井效果。
