Foundation trench supporting box for underground pipeline open excavation construction
The invention discloses equipment for supporting a pipeline foundation trench during underground pipeline open excavation construction, belongs to the field of underground pipeline construction equipment, and particularly relates to a foundation trench supporting box for underground pipeline open excavation construction. The foundation trench supporting box comprises a bottom-layer supporting box body and a heightened supporting box body; the bottom-layer supporting box body comprises a first soil retaining side wall, a second soil retaining side wall and cross braces which are parallel to each other and are only arranged at two ends of the bottom-layer supporting box body; and the heightened supporting box body comprises a first soil retaining side wall, a second soil retaining side wall and cross braces which are parallel to each other and are only arranged at two ends of the heightened supporting box body. The box-type supporting structure is assembled outside a pipeline foundation trench, the installation time of supporting equipment is shortened, during excavation operation, rock soil below leg wires of the bottom-layer supporting box body is excavated firstly, the supporting box is disengaged, then the supporting box is forced to sink by means of the gravity of a box body and the pressure or impact force of a bucket of an excavator, professional inserting and driving equipment is not needed, the supporting construction technology is simplified, and the work efficiency of supporting is remarkably improved.
本发明公开了一种用于地下管线明挖施工时，对管线基槽进行支护的设备，属于地下管线施工设备领域，具体来说是一种用于地下管线明挖施工的基槽支护箱。本发明包括底层支护箱和加高支护箱；底层支护箱包括第一挡土侧壁，第二挡土侧壁以及相互平行且仅布置在底层支护箱两端的横撑；加高支护箱包括第一挡土侧壁，第二挡土侧壁，相互平行仅布置在加高支护箱两端的横撑。这种箱式支护结构是在管线基槽外完成拼装，减少了支护设备安装时间，开挖作业时，先挖去底层支护箱脚线以下的岩土，使支护箱脱空，再利用箱体自身重力并挖掘机铲斗的压力或冲击力迫使其下沉，不需要专业的插打设备，简化了支护施工工艺，显著提高支护工效。
