Protective structure for underground chamber passing through existing building and construction method
The invention relates to a protective structure for an underground chamber passing through an existing building and a construction method. The protective structure comprises two support members and at least one cylindrical beam, the cylindrical beams are arranged in parallel at intervals, two ends of each cylindrical beam are respectively connected with the two support members, each cylindrical beam is located between an overlying existing building and a to-be-built underground chamber, the two ends of each cylindrical beam extend to the underground chamber and the outer side of the overlying existing building needing to be protected, the two support members are parallel to the tunneling direction of the underground chamber and located on the inclined upper portions of the two sides of the underground chamber respectively, each support member comprises an inclined extending section and a horizontal section which are sequentially arranged, the ends of each cylindrical beam are connected with the horizontal sections of the support members, and the outer ends of the inclined extending sections are connected with the underground chamber. The protection structure is reasonable in design, a supporting structure is built above the underground chamber, deformation of surrounding rock above the underground chamber can be effectively controlled, and the influence of excavation and construction of the underground chamber on an upper important structure is remarkably reduced.
本发明涉及一种地下硐室下穿既有建筑时的防护结构及施工方法，包括两个支撑构件和至少一根圆柱梁，各根圆柱梁间隔且平行设置，圆柱梁的两端分别和两个支撑构件相连，所述圆柱梁位于上覆既有建筑和拟建地下硐室之间，圆柱梁两端均延伸到地下硐室以及需要保护的上覆既有建筑外侧，两个支撑构件平行于地下硐室掘进方向，分别位于地下硐室两侧斜上方，支撑构件包括依次设置的倾斜延伸段、水平段，圆柱梁端部与支撑构件的水平段相连接，倾斜延伸段外端连接地下硐室，本防护结构设计合理，在地下硐室的上方建立支撑结构，可以有效控制地下硐室上方围岩的变形，显著降低地下硐室开挖建设对上部重要结构的影响。
