Embodiment

[0030] Such as figure 1 As shown, the prefabricated structure consists of two parts: prefabricated nodes and prefabricated lattice beams. The overlapping groove section of the prefabricated nodes is reserved according to the section size of the prefabricated lattice beams. An anchor hole 111, a pressure bearing plate 121 and an overlapping groove 131 for anchoring the anchor. Prefabricated lattice beams mainly consist of internal reinforcement cages and concrete. The concrete strength of the prefabricated lattice beam is not less than C20, and the size of the longitudinal reinforcement is not less than Stirrup size not less than The concrete protective layer is not less than 30mm, and the beam length should be selected as 2-3m.

[0031] The pressure-bearing plate on the upper part of the prefabricated node can be designed as hexagonal or circular, and a circular anchor hole is reserved in the middle. The pressure-bearing plate is made of steel, and the anchor head for anc...

Abstract

The invention belongs to the technical field of lattice slope protection, and provides a dry connection honeycomb assembly type lattice beam slope protection structure. The honeycomb assembly type lattice beam slope protection structure comprises middle joints, three kinds of side joints and lattice beams; and the joints and the lattice beams are in lap joint through lap joint grooves, and a honeycomb lattice slope protection structure is formed. The mode of prefabricated joints and prefabricated lattice beams is adopted, on-site assembly and installation are achieved, the construction speed is high, the construction period is shortened, and meanwhile the project quality is guaranteed; the connection mode of the joint and the lattice beam is simple, construction site personnel arrangement is reduced, and manpower and material resources are saved; and the structure joint does not need cast-in-place concrete, can play a role after installation is completed, and can quickly play a supporting role.

Description

technical field [0001] The invention belongs to the technical field of lattice structure slope protection, and relates to a dry-connected honeycomb-shaped assembled lattice beam slope protection structure. Background technique [0002] Lattice anchoring technology is a protection technology widely used in road and railway embankment and water diversion engineering slope reinforcement. Traditional slope lattice girders are mainly made of concrete cast-in-place, which has problems such as long construction period and difficulty in guaranteeing the quality of structural maintenance. Since the slope lattice beam exists in the natural environment, the long-term natural erosion makes the structure very easy to be damaged, which may lead to engineering accidents. Due to the short application time of lattice anchoring technology, the current theoretical research is relatively lacking, and the design is mainly based on engineering practice experience, which leads to many unreasonabl...
