Anchor cable recovery device and method based on hot melting structure

Abstract

The invention relates to an anchor cable recovery device and method based on a hot melting structure, the recovery device comprises a hot melting part, the hot melting part is provided with a shell clamped to an anchor cable bundle, and a hot melting reagent is packaged in the shell; a heating assembly coupled to the housing and in physical contact with the hot melt reagent; the controller is used for controlling the heating assembly to provide energy for the hot melting reagent; wherein in the state that the controller controls the heating assembly to physically heat the hot melting reagent, the hot melting reagent can release reaction heat energy based on physical heating, and the anchor cable bundle is fused through the reaction heat energy. The invention further relates to a recovery method based on the anchor cable recovery device, and the method comprises the steps that the heating assembly is installed on the shell and makes contact with the hot melting reagent in the shell; the shell is clamped to the anchor cable bundle, and the heating assembly is controlled by the controller to physically heat the hot melting reagent, so that the hot melting reagent releases chemical reaction heat; and enabling the hot melting reagent to be in contact with the anchor cable bundle so as to fuse and recycle the anchor cable bundle by means of chemical reaction heat.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, to the drilling technology of soil layers or rocks, and in particular to an anchor cable recovery device and method based on a hot-melt structure. Background technique [0002] At present, anchoring engineering is widely used in many neighborhoods such as foundation pits, tunnels, disaster management, etc. After reaching the expected goal, some components in the anchoring engineering, such as the anchor cables and bolts of the free section, lose their function, and these All components can be recycled, so taking them out can not only reduce material consumption, but also reduce construction costs and save resources. [0003] To this end, people have developed recyclable anchor cable technology. After the anchor cable completes the task, the anchor cable can be recycled, which can not only avoid the problem of the anchor cable exceeding the building red line, but also reduce the c...

Problems solved by technology

However, this type of heat-melt anchor needs to be energized to make the heat-melt ring reach a certain temperature before the anchor cable can be fused and recovered, so its recovery efficiency is low; secondly, the design of this type of heat-melt anchor The structure usually only considers the recovery of the free section of the anchor cable, and during the recovery process, with the movement of the anchor cable bundle, it is likely to affect the anchoring force of the original anchorage, and this type of hot-melt anchorage cannot be effective Monitor the real-time changes in the anchoring force during the recovery process of the anchor cable bundle, and cannot maintain or increase the anchoring force of the anchorage through corresponding means when the anchoring force weakens, so the application effect of this type of hot-melt anchorage is poor
