| description | The invention relates to a temporary side wall protection construction method adopting a double-side-wall pilot tunnel method, which comprises the following steps of: firstly digging a front hole and then digging a rear hole, reserving earthwork with a certain thickness in the direction, close to a middle construction area, of double side walls without digging, then spraying concrete on the surface of the earthwork for sealing, and after the digging is completed, removing the earthwork and the side walls together, therefore, the bearing capacity of the side wall is improved, and the side wall is prevented from collapsing to affect construction safety.
本发明涉一种双侧壁导坑法临时侧壁保护施工方法，其通过先挖先行洞后挖后行洞，并且在双侧壁靠近中间施工区域的方向预留一定厚度的土方不挖，然后在土方表面喷混凝土封闭，等挖掘完成后，将土方和侧壁一起拆除，以此提高侧壁的承受力，防止侧壁断塌影响施工安全。 |
