Environment-friendly prefabricated fast-assembly lattice beam and construction method

Abstract

The invention discloses an environment-friendly prefabricated fast-assembly lattice beam and a construction method. The lattice beam comprises a lattice beam body; the lattice beam body is in a grid shape and is formed by arranging and connecting a plurality of cross-shaped beam bodies; each cross-shaped beam body is of a reinforced concrete structure; a concrete groove for containing an anchor head is formed in the center intersection of a cross beam and a vertical beam of each cross-shaped beam body; a base plate is arranged in each concrete groove; the base plates and the concrete grooves are provided with corresponding anchor holes; and ecological geotextile bags are placed in grids of the lattice beam body. The lattice beam has the advantages of short construction period, manpower andmaterial resource saving, environmental protection and the like, can be disassembled and assembled, and can realize industrialization.

Description

technical field [0001] The invention relates to the technical field of slope reinforcement and support, in particular to a green and environment-friendly prefabricated quick-install lattice beam and a construction method. Background technique [0002] With the development of the times, the number of civil engineering constructions in mountains, plateaus, hills and other areas in our country has gradually increased. During the construction process, a large number of exposed slopes will appear, and the surface plants of the slopes will be destroyed, which will easily lead to soil erosion and even landslides. Therefore, the slope must be reinforced; the cast-in-place reinforced concrete lattice structure can provide greater anti-sliding resistance, has better integrity and can work well with prestressed anchor cables to bear forces, so it is widely used in various types and heights in China. Widely used in slope reinforcement. [0003] However, the currently commonly used cast...

Problems solved by technology

[0003] However, the currently commonly used cast-in-place reinforced concrete lattice has the following disadvantages: first, the concrete pouring time is long, which will lead to a long construction period; second, the concrete pouring is prone to quality problems such as beams not being compacted during vibration; Third, the reinforcement and concrete pouring require a large number of workers, which cannot be modernized; fourth, because the concrete lattice is not biodegradable, it cannot be naturally integrated with the slope soil, which is not conducive to environmental protection
