Abstract

The invention discloses a recovery-type anchorage device. The recovery-type anchorage device comprises an anchor cable and an anchoring seat, wherein a rigid inner taper sleeve is welded at the middle portion of the anchoring seat, inner taper sleeve is provided with a circular-table-shaped cavity, two opposite conical tables are arranged at the top of the cavity, and a bypass groove is formed in a position located between the two conical tables, on the side surface of the cavity; the anchor cable penetrates through the inner taper sleeve, a fastening sheet is placed between the two conical tables and the anchor cable respectively, and the fastening sheet is higher than the conical tables; the fastening sheet is sequentially stacked with a planar bearing and a spring along the axial direction of the anchor cable, and locked on the inner taper sleeve by a locking sleeve; the portion longer than the locking sleeve, of the anchor cable, and the locking sleeve are coated and protected by a protection sleeve. The recovery-type anchorage device disclosed by the invention has the features of being simple in structure, convenient and fast to detach, greatly reduces the cost of the anchor cable, and increases the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of protection of deep foundation pits in building construction, in particular to an anchorage for detachable and recoverable anchor cables after temporary protection and a method for using the same. Background technique [0002] As a technology, prestressed anchoring is used in various civil engineering for building foundation pits and foundation reinforcement. From prestressed anchor rods at the beginning of the last century to anchoring in the 1950s and soil nailing technology in the 1970s, it has developed to the present Anchor technology. Anchor cable technology has been widely used at home and abroad, involving highways and railways, deep tunnels, civil defense, basements, geotechnical engineering slope treatment, etc. In the early days, ordinary anchor cables were used as temporary enclosures, and they were buried underground together with the built buildings for a long time, forming underground garba...
