Pipe-jacking working well structure and construction method thereof
The invention relates to the field of underground geotechnical engineering, in particular to a pipe-jacking working well structure. According to the working well structure, a connecting hole is downwards formed in the ground, a first connecting cylinder and a second connecting cylinder are arranged in the connecting hole, the second connecting cylinder is arranged on the upper side of the first connecting cylinder, a fixing mechanism for fixing the second connecting cylinder is arranged between the first connecting cylinder and the second connecting cylinder, a plurality of first soil nails are inserted into the first connecting cylinder and the second connecting cylinder respectively, the first soil nails are inserted into a geological layer, one ends of the first soil nails are fixedly connected with first fixing plates, and the first fixing plates abut against the inner wall of the first connecting cylinder and the inner wall of the second connecting cylinder. The invention furtherdiscloses a construction method of a pipe-jacking working well. The effect of improving the stability of the working well is achieved.
本申请涉及地下岩土工程的领域，尤其是涉及一种顶管工作井结构，地面向下设有连接孔，所述连接孔内设有第一连接筒和第二连接筒，所述第二连接筒置于第一连接筒的上侧，所述第一连接筒和第二连接筒之间设有将第二连接筒固定的固定机构，所述第一连接筒和第二连接筒分别插接有若干个第一土钉，所述第一土钉插入地质层内，所述第一土钉的一端固定连接有第一固定板，所述第一固定板分别与第一连接筒和第二连接筒的内壁抵接。本申请还公开一种顶管工作井施工方法。本申请具有增加工作井稳定性的效果。
