Problems solved by technology

For important anchor cables, it is required that all parts from the inner anchor section to the anchor head must achieve double anti-corrosion, and it is required to test the insulation resistance value of the anchor cable after installation to determine the reliability of its anti-corrosion performance. The process is cumbersome and cannot be used well in engineering practice

Abstract

The invention relates to a repairable anchor cable structure after an earthquake and an application method thereof, characterized in that the repairable anchor cable structure after an earthquake is characterized in that it includes an anchor hole arranged on the rock mass and an anchor hole arranged in the anchor hole The inner anchoring body, the anchoring body includes at least one steel strand, an anchor head connected to the inner end of the steel strand, a strip-shaped hot-melt strip arranged in the length direction of the steel strand, and a strip-shaped hot-melt strip arranged in the strip-shaped hot-melt strip The expansion bag of the steel strand and the hot melt strip is provided with a heating wire for heating and melting the hot melt strip, and an anchoring agent is filled between the steel strand, the hot melt strip, the heating wire and the anchor hole. The invention is beneficial to realize the repair of the anchor cable after the earthquake.

Description

Technical field: [0001] The invention relates to the field of anti-seismic support for underground engineering, in particular to a repairable anchor cable structure after an earthquake and an application method thereof. Background technique: [0002] The anchor cable can give full play to the self-supporting potential of the rock mass, adjust and improve the self-strength and self-stabilization ability of the rock and soil, reduce the self-weight of the support structure, save engineering materials, and ensure the safety and stability of the construction, so as to obtain an ideal support It has significant economic and social benefits and has been widely used in geotechnical engineering and other underground engineering fields. [0003] China is located between the two largest earthquake-concentrated regions in the world. It is a country with many earthquakes in the world and one of the countries that suffer the most serious earthquake disasters. When an earthquake occurs, t...
