Foundation pit tube well rear shut-in well structure
The invention discloses a foundation pit tube well rear shut-in well structure in the technical field of foundation pit construction, which comprises a steel casing inserted in a sand-free well tube, an inner filler filled in the steel casing and an outer filler laid around the steel casing, and the outer filler comprises a concrete cushion layer, a waterproof layer, a fine stone concrete layer and a raft concrete layer from bottom to top in sequence. A first reinforcing steel bar frame and a second reinforcing steel bar frame are arranged on the outer wall of the steel casing and located in the raft concrete layer and the concrete cushion layer respectively, a plurality of straight reinforcing steel bars are arranged between the first reinforcing steel bar frame and the second reinforcing steel bar frame, and the lower ends of the straight reinforcing steel bars are inserted into rock mass on the periphery of a well mouth of the sand-free well pipe. The first reinforcing steel bar frame, the second reinforcing steel bar frame and the straight reinforcing steel bars on the outer wall of the steel casing are used as inner connecting frames, so that the concrete cushion layer, the waterproof layer, the fine stone concrete layer and the raft concrete layer can be connected more tightly to form a whole, the waterproof layer cannot be damaged due to dislocation of the steel casing and the concrete layer, and the service life of the raft concrete layer is prolonged. And the waterproof effect of the whole well sealing structure is improved.
本发明公开的是基坑施工技术领域的一种基坑管井后封井构造，包括插设在无砂井管中的钢护筒，以及填充在钢护筒内的内填料和铺设在钢护筒周围的外填料，所述外填料从下往上依次为混凝土垫层、防水层、细石砼层和筏板砼层，所述钢护筒外壁上设有第一钢筋架和第二钢筋架，二者分别位于筏板砼层和混凝土垫层内，第一钢筋架与第二钢筋架之间设置有多根直钢筋，其下端插入到无砂井管井口周边的岩体内。本发明利用钢护筒外壁上的第一钢筋架、第二钢筋架和直钢筋作为内连接架，可以使混凝土垫层、防水层、细石砼层和筏板砼层之间连接更加紧密，形成一个整体，不会因为钢护筒与砼层发生错动而使防水层发生破坏，提高了整个封井构造的防水效果。
