Abstract

The invention provides an assembly type framework beam anchor cable supporting structure. The assembly type framework beam anchor cable supporting structure comprises an assembly type framework beam,pre-stress anchor cables and an alien soil spraying face; the assembly type framework beam is composed of mutually connected prefabricated cross beams; through-length rebars are arranged in the prefabricated cross beams; lifting hooks and fixing rebars are pre-buried in the two ends of cross beams and vertical beams; an anchor cable hole is formed in the center of each prefabricated cross beam; through-length rebar joints between the prefabricated cross beams are mutually connected through mechanical connection joints; concrete is poured at the joints between the prefabricated cross beams to form a whole; the pre-stress anchor cables pass through the anchor cable holes and are fixed to the prefabricated cross beams by anchorage devices; and the lifting hooks on the prefabricated cross beams are connected with soil nails through slings. The assembly type framework beam anchor cable supporting structure is suitable for rock side slope supporting, construction is convenient, prefabricatedframework beam components can be directly fixed to a supporting surface layer, and scaffold installing is omitted; and the assembly type framework beam is adopted, the components are prefabricated ina factory, and the field construction difficulty is reduced; and meanwhile, a cast-in-situ segment template support can be directly fixed to the prefabricated components, and the construction speed is increased.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to an assembled frame beam anchor cable support structure and a construction method thereof. Background technique [0002] The prestressed anchor cable frame support system is a new type of active flexible support structure that appeared in the 1990s, and has been widely used in the repair and reinforcement of railway and highway slope diseases. The structure is a new type of reinforcement system that integrates reinforced concrete frame beams and prestressed anchor cables. The sliding force of the rock and soil mass generated during the slide maintains the stability of the rock and soil mass of the slope. However, in many cases, due to the steep slope of the support, the construction of the frame beam is relatively difficult, and the binding of steel bars and the positioning of the formwork are very difficult. At the same time, the harsh construction environment...
