Excavation and protection process for high cutting adjacent to railway business line
The invention discloses an excavation and protection process for a high cutting adjacent to a railway business line, and relates to the technical field of cutting construction, which comprises the following steps: temporarily pulling a protective net, grooving a mountain body and performing layered construction, building a construction platform when the cutting is excavated to the middle position, excavating a rock falling groove in the construction platform, and performing slope protection construction on a formed side slope. A gentle slope surface is excavated and reinforced, a foundation is reinforced, an anchoring pile is built, a base is installed on the top of the anchoring pile, a prefabricated slab is installed in the base, reinforcing is conducted through an anti-pulling anchor rod and an inclined supporting column, and a buffer layer is built through generated gravel and waste slag. According to the invention, the impact of geological disasters such as slope collapse and rockfall on an adjacent railway business line can be prevented, and the protection failure caused by the looseness of the protection fixing mechanism due to vibration load generated by frequent departure of a heavy-load train is avoided.
本发明公开了一种邻近铁路营业线高路堑开挖及防护工艺，涉及路堑施工技术领域，包括临时拉设防护网、对山体开槽并分层施工，在路堑挖方至中间位置时修建施工平台，在施工平台处开挖落石槽，对形成的边坡进行护坡施工，对缓坡面开挖并加固，对地基加固并筑造锚固桩，锚固桩的顶部安装底座，在底座内安装预制板并通过抗拔锚杆和斜向支撑柱进行加固，利用产生的碎石和弃渣修筑缓冲层。本发明能够防止由于边坡溜塌、落石等地质灾害对临近铁路营业线的冲击，避免重载列车频繁驶离产生的震动载荷造成的防护固定机构松动，引发的防护失效。
