A detachable anchoring tool and its removal method

Abstract

The invention discloses a demountable anchoring tool and a demounting method of the demountable anchoring tool. The demountable anchoring tool comprises a steel strand and a lockset used for locking the far end of the steel strand, the exposed section of the steel strand is sleeved with a sleeve pipe, the lockset comprises a barrel, a pressure bearing plate is fixed to the near end of the barrel, the barrel is filled with heat loss type high-strength materials, electric heating bodies are pre-buried in the heat loss type high-strength materials and are connected with a conductive wire, the conductive wire penetrates out of the barrel and extends outwards, and the far end of the steel strand penetrates through the pressure bearing plate, enters the barrel and is locked by the heat loss type high-strength materials. In the demounting process, the conductive wire is powered on, the electric heating bodies heat, the heat loss type high-strength materials are heated and damaged, binding force on the steel strand is lost, the steel strand automatically pops outwards under the action of the elasticity of the steel strand, and automatic demounting is achieved. The demountable anchoring tool is simple in structure, and can be conveniently demounted without arranging tensile equipment outside in the demounting process.

Description

technical field

[0001] The invention relates to the field of geotechnical engineering, in particular to a detachable anchoring tool and a removal method thereof. Background technique

[0002] Anchor tools are widely used in geotechnical engineering fields such as building foundation pits, roads, bridges, ports, etc., but when they are no longer used, they will lose their meaning and be placed underground, and it is difficult to remove them.

[0003] With the development of cities, underground space has also become a scarce resource. However, when developing underground space, such as building subways, underground buildings, underground pipelines, and building support piles, these abandoned anchoring devices have become obstacles and have to be Demolitions add cost, but sometimes the difficulty of demolition makes the construction of new buildings impossible.

[0004] In order to solve the problem in this development, the detachable anchoring appliance has just emerged at th...
