Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, in particular to a combined supporting structure for a rock slope with developed fissures. Background Art

[0002] The development of fissures refers to the fact that the rock type, structure and climate are greatly affected by weathering, and more and more obvious cracks are produced due to weathering, water dissolution and geological structure.

[0003] When cracks develop in the slope, a support structure needs to be set up to avoid or reduce the collapse area and reduce the occurrence of safety accidents. The Chinese patent with the announcement number CN204875815U discloses a slope support structure, including a slope support net supported on the surface of the slope, an anchor rod connected to the slope support net, the inner end of the anchor rod is provided with a tip and inserted into the slope, the outer end of the anchor rod is welded to the node of the slope support net, and the rod body of the anchor rod is provided with a threaded slurry pattern along the length direction of the anchor rod; a steel pipe is provided in the middle of the slope, the inner end of the steel pipe is vertically inserted into the slope, the outer end of the steel pipe is welded to the node of the slope support net, and the lower end of the steel pipe is lower than the bottom end of the slope. The utility model reduces the cost of slope support by combining a new anchor rod with a slope support net, while improving the support effect and construction efficiency.

[0004] Although the above patent plays a role in slope support, during installation, it is necessary to insert the anchor rod into the anchoring rock and soil layer, then perform grouting for reinforcement, and then weld the anchor rod to the node of the slope support net, which makes the installation and disassembly of the slope support structure more troublesome and inconvenient to use.
