Excavation construction method for high road cutting beside existing road
The invention discloses an excavation construction method for a high road cutting beside an existing road. The excavation construction method includes the following steps that A, anchor rod construction is conducted on the side slope face of the existing road, and anchor rods are made to enter a road cutting rock mass needing to be excavated; B, a protective shed frame is built on the face adjacent to a slope and is connected with the anchor rods to form an integral structure, and a flexible protective frame is installed on the inner side of the protective shed frame; and C, step-by-step excavation construction is conducted on the road cutting. According to the excavation construction method, holding and supporting are conducted on loose earth-rock, falling towards the side of the existingroad after excavation, through the protective shed frame and the flexible protective frame, and the side pressure of the excavated loose rock mass can be uniformly transferred to the anchor rods through the protective shed frame and is then transferred to a side slope vertical wall stable rock layer through the anchor rods. By means of the method, it can be ensured that traffic of the existing road is smooth, and compared with a conventional disposal method, the construction cost can be saved, and safety accidents caused when excavation flying objects, rolling stone and the like fall into theexisting road can also be avoided.
本发明公开了一种既有道路旁高路堑开挖施工方法，包括以下步骤：A、在既有道路边坡面进行锚杆施工，使锚杆进入需开挖的路堑岩体；B、在临坡面搭设防护棚架并与锚杆连接形成整体结构，并在防护棚架内侧安装柔性防护架；C、对路堑进行逐级开挖施工。本发明通过防护棚架及柔性防护架对开挖后向既有道路侧坠落的松散土石方进行兜托，防护棚架可将开挖后的松散岩体的侧压力均匀传递给锚杆，再由锚杆传递至边坡立壁稳定岩层，该方法既可以保障既有道路交通畅通，与常规处置办法相比，能节约施工成本，又可以避免开挖飞散物、滚石等落入既有道路内造成安全事故。
