Problems solved by technology
When the slope protection structure is demolished for its functional use, the entire structure is basically waste. Not only is the cost of dismantling high, but also a large amount of waste is generated and needs to be discharged to a dedicated dump, causing secondary pollution to the environment.
The construction period of this structural domain is long, construction cannot be carried out in winter in the north, labor intensity is high, and the cost is high, which also has a certain impact on the environment

The invention discloses a novel corrugated steel plate lattice structure for slope protection, and belongs to the technical field of slope protection engineering. The novel corrugated steel plate lattice structure comprises an expansion joint structure and a plurality of sets of grid structures, wherein each grid structure comprises an anchor rod, an anchor rod head locking component, a cross beam, a longitudinal beam, an anchor rod head locking concave gasket and an anchor rod head locking elastic nut; and the expansion joint structure comprises a left side cross beam, a right side cross beam, a sliding plate, a partition plate, a filling material, a protective plate, a steel sleeve, a connecting bolt and a nut. All the components of the novel corrugated steel plate lattice structure are machined in a factory, the occupied area of a site is small, no noise is generated, the construction period is short, the novel corrugated steel plate lattice structure is not affected by temperature, a slope protection structure can be repeatedly used, and no waste is generated.
Description
technical field [0001] The invention relates to a novel corrugated steel plate lattice structure used for slope protection, and belongs to the technical field of slope protection engineering. Background technique [0002] Anchorage technology is an important technology in underground and slope engineering construction. It uses the anchoring force of soil and rock mass to maintain the stability of underground structures or slopes and prevent them from collapsing, slipping, overturning and other disasters. The construction safety is guaranteed and the slope deformation is stabilized. In the 1950s, the anchoring technology was only used as a temporary measure to support the slope and the soil wall. In the 1960s, the anchor rod was used as a permanent support instead of the lining in foreign countries, and it was widely used. However, my country began to study and develop it in the 1980s. using this method of support. In the early engineering practice, the mechanism model of ge...
