Problems solved by technology

For this reason, the present application proposes a composite protection structure for dangerous rock mass. In the process of tensioning the tension steel cable after the tension force becomes smaller, the composite protection structure for dangerous rock mass is in a tensioned state. , reduce the need to release all the tension of the tension cable, effectively improve the protection structure of the dangerous rock mass in the related technology, and it is not convenient to increase the tension cable without releasing the tension force of the tension cable tension

Abstract

The embodiment of the invention provides a dangerous rock mass composite protection structure and relates to the field of dangerous rock mass protection. The dangerous rock mass composite protection structure comprises a rock mass assembly and a protection net assembly. After a steel wire rope on the winch part is tightened and a first steel rope is stressed and tensioned, a second rope buckle at a second lantern ring is gradually unfastened till the second rope buckle relieves pressing of the first steel rope, then the steel wire rope on the winch part is tightened to drive the first steel rope to be tightened, meanwhile, after the tensioning force of the first steel rope is gradually increased and the first steel rope drives the protective net to be tensioned, the second rope buckle is screwed, a purpose of tensioning the tensioning steel rope with the smaller tensioning force is achieved, in the process, the first steel rope is in the tensioning state, the situation that all the tensioning force of the tensioning steel rope needs to be relieved firstly is reduced, the dangerous rock body protection structure in the related technology is effectively improved, and the tensioning force of the tensioning steel cable is inconvenient to increase under the condition that the tensioning force of the tensioning steel cable is not relieved.

Description

technical field [0001] This application relates to the technical field of dangerous rock mass protection, in particular, to a composite protective structure for dangerous rock mass. Background technique [0002] In the protection structure of dangerous rock mass in the related technology, the prestress provided by anchors is used to fix the dangerous rock mass and the main rock mass in advance, so that the structural surface is in a compacted state, so as to improve the integrity of the dangerous rock mass and the main rock mass , so as to fundamentally improve the mechanical properties of the rock mass, effectively control the displacement of the rock mass, and then cover and wrap the dangerous rock mass with a wire rope net to limit the weathering, peeling or damage of the dangerous rock mass and the collapse of the rock layer, and play a reinforcing role , to control the movement of falling rocks within a certain range, and play a protective role. At present, during the u...
