Novel large deformation anchor cable component

Abstract

The invention provides a novel large deformation anchor cable component. The novel large deformation anchor cable component comprises an outer sleeve; the outer sleeve is provided with a fastener; thefastener is pressed against an inner sleeve in the outer sleeve; the inner wall of the inner sleeve is sloped; the inner sleeve is internally provided with a sliding body attached to the inner wall;and the sliding body is connected with a steel strand. A prestressed anchor cable with large deformation, adjustable tension and an energy absorption function is provided by the invention, can not only strengthen rock and soil mass, but also monitor deformation force and the deformation process in the rock and soil mass by being matched with corresponding mechanical sensors and displacement sensors, and then scientific data of the two aspects are fitted, and have great significance for deformation mechanism and laws of mass and soil mass research. In addition, the tensile resistance of the anchor cable can be manually adjusted according to different engineering conditions and time effects, so that a high tensile state is maintained while the tension resistance is lower than the maximum breaking force of the anchor cable, and thus the great significances of ensuring engineering safety and using the anchor cable in an optimized mode are achieved.

Description

technical field [0001] The invention relates to rock and soil mass support, in particular to a novel large-deformation anchor cable member. Background technique [0002] Since human beings have transformed nature in order to survive, they have begun to "deal" with rocks and soils (hereafter referred to as rocks and soils), and the disasters caused by the deformation of rocks and soils in this process It often happens, especially in modern society, the increasing production activities of human beings make the disasters related to rock and soil mass more frequent and severe. For example, large-scale landslides, debris flows, chamber collapses, extreme deformations of roadways (rock bursts, roof collapses, floor drums), earthquakes, etc. [0003] In these struggles, human beings have paid a heavy price, but at the same time, they have also summed up a series of methods to deal with rock and soil disasters, especially according to the mechanism and law of disaster occurrence, a...
