Three-stage plugging construction method for dewatering well
The invention relates to the technical field of foundation pit dewatering construction, in particular to a three-stage blocking construction method for a dewatering well. Comprising the following steps that S1, reinforcing ribs are arranged, and a sleeve is installed; s2, a structural bottom plate is laid for waterproofing; s3, water swelling strips are installed at the welding positions of the two layers of wing plates and the lower portion of the straight barrel; s4, bottom plate concrete is poured; s5, after the structural construction is completed and the design strength is reached, starting to plug the dewatering wells in sequence; s6, the water level of the self-priming pump is lowered, a first-layer blocking steel plate with a thread steel pipe is installed, and a thread of the steel pipe is wound with a raw material belt; s7, a second waterproof layer is arranged, and micro-expansion impervious concrete is poured; s8, a third double-layer waterproof steel plate layer is arranged, and the middle portions of the two layers of steel plates are filled with micro-expansion impervious concrete; and S9, the edge of the sleeve higher than the bottom plate surface is cut, and the bottom plate is repaired, filled and leveled up through waterproof concrete. The construction method is easy to operate, and the plugging effect of the dewatering well is guaranteed through the three-level waterproof measures in the sleeve and other methods. The method is mainly applied to dewatering well plugging construction.
本发明涉及基坑降水施工技术领域，更具体而言，涉及一种降水井三级封堵施工方法。包括以下步骤：S1、布置加强筋，安装套筒；S2、铺设结构底板防水；S3、两层翼板与直筒下部焊接位置处安装遇水膨胀止水条；S4、浇筑底板混凝土；S5、结构施工完并达到设计强度后开始按顺序封堵降水井；S6、自吸泵降低水位，安装带螺纹钢管的第一层封堵钢板，钢管螺纹处缠生料带；S7、设置第二层防水层，浇筑微膨胀抗渗混凝土；S8、设置第三层双层防水钢板层，两层钢板中部填充微膨胀抗渗混凝土；S9、切割高出底板面套筒边缘，利用防水混凝土修补填平底板。本工法操作简单，套筒内三级防水措施等方法，保证了降水井封堵效果。本发明主要应用于降水井封堵施工方面。
