Prefabricated lattice beam structure for slope reinforcement and assembly overall construction method

Abstract

The invention discloses a prefabricated lattice beam structure for slope reinforcement and an assembly overall construction method. According to the method, reinforced concrete lattice beams shaped like Chinese characters 'tian' are prefabricated in a PC component factory, then the prefabricated lattice beams serve as basic assembly units to be safely assembled in a slope construction site sectionby section and layer by layer along with excavating or filling, and the prefabricated lattice beam structure can be applied to reinforcement treatment of cut slopes and also applied to reinforcementtreatment of fill slopes; the prefabricated lattice beams can be assembled downwards from the top faces of the slopes and also assembled upwards from slope toe lines; and after the prefabricated lattice beams are mounted and assembled in place, concrete of reserved space between the adjacent prefabricated lattice beams is poured and tamped, and post-poured superimposed longitudinal and cross beamsare formed. Thus, the prefabricated lattice beam structure for slope reinforcement and the assembly overall construction method are beneficial for achieving lattice beam slope reinforcement rapid andsafe assembly overall construction and worthy of being popularized.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a prefabricated lattice beam structure for slope reinforcement and an assembly integral construction method. Background technique [0002] Lattice reinforcement technology is a slope reinforcement technology that uses grouted stones, cast-in-place reinforced concrete or prefabricated prestressed concrete lattices for slope protection, and uses anchor rods or anchor cables to fix them. The lattice structure technology is generally combined with the beautification of the surrounding environment. Using the grid to protect the slope and planting flowers and plants in the grid can achieve an extremely beautiful effect. This technology is widely used in the reinforcement of high and steep slopes in mountainous expressways, and its slope protection achieves good results that are both beautiful and safe. [0003] The main function of the lattice structure is to distribute the rem...

Problems solved by technology

[0005] In view of the following disadvantages of the mortar block stone lattice and cast-in-place reinforced concrete lattice commonly used in China at present: ①It requires a long time of maintenance, which is not conducive to the early stability of the slope, and cannot be used for slope emergency projects; ②On-site construction requires More formwork and construction workers are not conducive to the realization of rapid installation of building industrialization; ③Generally, the conditions of the construction site are harsh, setting formwork on the slope, pouring concrete is prone to formwork slipping, displacement and concrete leakage affecting the support structure Unfavorable conditions of quality occur from time to time; ④The currently commonly used lattice forms are usually set on the slope after the excavation or filling of the entire slope is completed, and generally cannot be layered step by step with the excavation or filling of the slope. During construction, the safety problem of slope reinforcement construction is significant; ⑤The vibration of the concrete on site greatly disturbs the slope, and even induces the occurrence of large-scale landslides and other geological disasters
