Zipper type ground fracture repairing device and using method

Abstract

The invention relates to a zipper type ground fracture repairing device and a using method. The device comprises a ground fracture; a plurality of cover plates are covered along the length direction of the ground fracture; each cover plate comprises a cuboid first cover plate and a cuboid second cover plate which are the same in size; first buckling parts are arranged at the ends, in the length direction, of the first cover plates, second buckling parts are arranged at the ends, in the length direction, of the second cover plates, the two first cover plates are matched through the first buckling parts to form a main cover plate, the first buckling parts of the first cover plates and the second buckling parts of the second cover plates are matched to form auxiliary cover plates, and the cover plates are further filled with multiple layers of materials. The cover plate can adapt to the ground fracture, so that the cover plate can better adapt to horizontal tension deformation, vertical dislocation deformation and slight twisting deformation of the ground fracture, roadbed engineering on the ground crack is ensured to be safe and stable, and engineering construction safety on the ground crack is ensured.

Description

technical field [0001] The invention relates to the technical field of ground fissure engineering, in particular to a zipper type ground fissure repairing device and a using method. Background technique [0002] Ground fissure refers to the linear cracking phenomenon in rock or soil directly reaching the surface. It is a kind of ground deformation disaster in geological disasters. It is a geological event that directly or indirectly deteriorates the environment, reduces environmental quality, and endangers the development of human beings and the biosphere. , has become a new and independent natural disaster category. [0003] The ground fissure disaster is caused by the slow creeping expansion of the structure, and changes slowly with the erosion and subsurface erosion of the surface precipitation infiltration. Soil holes in the overburden layer are formed first. After the rainfall increases suddenly and the soil is saturated with water, the soil weight of the overburden la...

Problems solved by technology

[0006] At present, for the ground fissures that have occurred, methods such as direct backfilling, foundation soil compaction pile reinforcement, geogrid flexible reinforcement, pile raft, and pile slab rigid reinforcement are usually used for repair. The advantages and disadvantages of the above methods are obvious, and flexible treatment measures The ability to adapt to the deformation of ground fissures is strong, but the deformation of the subgrade body is too large, which cannot guarantee the rigidity of the project body; the construction cost of rigid measures is high, and the ability to adapt to the deformation of cracks is poor; the waterproof and drainage effect of groundwater is not ideal
