Reverse construction method of plate rib type anchor rod retaining wall process
The invention discloses a reverse construction method of a plate rib type anchor rod retaining wall process, and aims to solve the problem that the plate rib type anchor rod retaining wall process of an ultrahigh steep rock slope is difficult to link, greatly reduce the link time of the earth-rock slope descending or slope cutting, anchor rod and anchor cable driving and retaining wall concrete pouring processes, reduce the influence of a single process on other processes, and improve the working efficiency of the plate rib type anchor rod retaining wall. The construction period is shortened; on the other hand, after rapid slope descending is completed, anchor rod driving is conducted immediately, retaining wall concrete pouring construction is conducted, the exposure time of the ultrahigh steep rock slope is shortened, and the safety risk is reduced; in addition, due to the fact that the anchor cable is driven after slope descending of earthwork, damage to the anchor rod and the anchor cable in the slope descending process of the earthwork is avoided, the axis of the anchor cable can be kept pulled after the anchor cable is driven, and the finished product of the plate rib type anchor rod retaining wall anchor cable after construction is completed is good in quality and high in drawing resistance. The problem that according to an existing plate rib type anchor rod retaining wall construction method, the axis of an anchor cable cannot be pulled easily is solved.
本发明公开了一种板肋式锚杆挡墙工艺逆作施工方法，针对超高陡峭岩石边坡的板肋式锚杆挡墙工序衔接困难，大幅度减小土石方降坡或削坡与锚杆锚索打设、挡墙混凝土浇筑的工序衔接时间、减小单项工序对其他工序产生的影响，有利于缩短工期；另外一方面，在快速降坡完成后，随即进行锚杆打设，并进行挡墙混凝土浇筑施工，减少超高陡峭岩石坡面暴露时间，减小安全风险；此外，由于锚索在土石方降坡后完成打设，避免了土石方降坡过程中对锚杆锚索的破坏，而且锚索打设后能够保持轴心受拉，使得施工完成后的板肋式锚杆挡墙锚索成品质量好，抗拉拔力高。本发明解决了现有的板肋式锚杆挡墙施工方法易造成锚索无法轴心受拉的问题。
