Protection construction method for high and steep edge upward slope of mountain tunnel portal
The invention discloses a mountain tunnel portal high and steep edge upward slope protection construction method which comprises the following steps: S100, mounting a cable crane system, and transporting materials to a construction slope surface by using the cable crane system in combination with a manual secondary reshipment mode; s200, a construction platform is erected on the construction slope in the mode that a floor scaffold and an overhanging scaffold are combined; s300, a temporary passive protective net is built between the cross construction positions of the construction slopes; s400, a manufacturability test is conducted, specifically, whether the drilling technology meets the field geological condition or not is determined through a hole forming test, and follow-up grouting construction technical parameters are obtained through a grouting test; s500, slope toe reinforcement protection of the high and steep slope is conducted; s600, slope surface protection of the high and steep slope is conducted, and the dangerous rock and the stable mountain body are anchored into an integral structure; and S700, guiding type, covering type and active and passive protective net construction is conducted so as to guide and intercept falling rocks. When the method is used for reinforcing and protecting the high and steep edge upward slope, the problems of instability, falling and the like of dangerous rocks can be effectively avoided, and the railway operation safety is ensured.
本发明公开了一种山岭隧道洞口高陡边仰坡防护施工方法，包括步骤：S100.安装缆索吊系统，使用缆索吊系统结合人工二次倒运的方式运输材料至施工坡面；S200.在施工坡面上使用落地脚手架和悬挑脚手架结合的方式搭设施工平台；S300.在施工坡面交叉施工位置之间建造临时被动防护网；S400.进行工艺性试验，包括通过成孔试验确定钻孔工艺是否符合现场地质条件，通过注浆试验获取后续注浆施工技术参数；S500.进行高陡边坡的坡脚加固防护；S600.进行高陡边坡的坡面防护，将危岩与稳定山体锚固为整体结构；S700.进行引导式、覆盖式及主被动防护网施工，以引导拦截落石。使用这种方法进行高陡边仰坡加固防护，能够有效避免危岩失稳、掉落等问题发生，确保铁路运营安全。
