Abstract

Specifically, the invention is a construction method for reducing the safety risk of the reverse construction method of the ribbed anchor retaining wall, which solves the problems of high safety risks during the construction of the existing ribbed anchor retaining wall reverse method, and the inability to achieve both construction safety and shortened construction period. A construction method to reduce the safety risk of the reverse method of ribbed anchor retaining wall, S1: preparation of double-knife surrounding rock cutting tool; S2: assembly and adjustment of double-knife surrounding rock cutting tool; S3: on the surrounding rock wall Grooving; S4: Opening of anchor holes; S5: Assembly of threaded steel anchors and their auxiliary structures; S6: Putting threaded steel anchors and pouring cement mortar; S7: Binding steel bars, erecting formwork, and pouring concrete; S8: Seal the threaded steel anchor rods on the outside of the panel. The invention has the advantages of reasonable structural force, perfect function of auxiliary devices, etc., and has remarkable safety benefits, construction period benefits, and cost benefits. It can be popularized and applied in deep foundation pits, steep slopes, etc., and can also be used for reference in similar projects.

Description

technical field [0001] The invention relates to a construction method for stonework excavation of a high slope stability protection project, in particular to a construction method for reducing the safety risk of the reverse operation method of a ribbed anchor retaining wall. Background technique [0002] The ribbed anchor retaining wall is a light protective structure developed in recent years for vertical excavation of the air surface. Because of its small amount of work and fast construction, it is widely used in deep foundation pit walls and steep high slopes. application. For the taller ribbed anchor retaining wall, the top-down construction method of segmental excavation and protection at the same time was developed. The self-weight is all borne by the anchor rod of the upper retaining wall itself (suspension function), which requires that the anchor rod of the upper retaining wall must reach the design strength. [0003] However, the practice shows that the following...
