Construction method for reducing safety risk of ribbed anchor rod retaining wall reverse construction method

Abstract

The invention particularly relates to a construction method for reducing the safety risk of a ribbed anchor rod retaining wall reverse construction method. The problems that during existing ribbed anchor rod retaining wall reverse construction method construction, the safety risk is high, and construction safety and construction period shortening cannot be achieved at the same time are solved. Theconstruction method for reducing the safety risk of the ribbed anchor rod retaining wall reverse construction method comprises the steps that S1, a double-cutter type surrounding rock cutting tool isprepared; S2, the double-cutter type surrounding rock cutting tool is assembled and adjusted; S3, a groove is cut in a surrounding rock wall; S4, an anchor rod hole is formed; S5, a threaded steel bar anchor rod and an auxiliary structure of the threaded steel bar anchor rod are assembled; S6, the threaded steel bar anchor rod is placed in, and cement mortar is poured; S7, steel bars are bound, aformwork is erected, and concrete is poured; and S8, the threaded steel bar anchor rod is subjected to anchor sealing on the outer side of a panel. The construction method has the advantages that thestructure stress is reasonable, and the functions of an auxiliary device are complete, the safety benefit, the construction period benefit and the cost benefit are all remarkable, and the construction method can be applied and popularized in deep foundation pits, steep slopes and other occasions 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...
