Embodiment Construction

[0028] The present invention will be described in further detail below in combination with the accompanying drawings, and specific implementation methods will be given.

[0029] Such as figure 1 , figure 2 , image 3 The shown U-shaped anchor cable can be recovered from the main reinforcement of the working cable, and the U-shaped anchor cable includes an anchor head 1 and a plastic sleeve 15 . Described anchor head 1 comprises housing cover 6, bearing base plate 12 and column 2, and bearing base plate 12 closes the bottom of housing cover 6, and column 2 is arranged on the middle part of bearing base plate 12, is respectively provided with on the bearing base plate 12 of column 2 bottoms The first perforation 23 for the working cable 13 to pass through, a set of clamping device for clamping the working cable 13 is provided above the first perforation 23; the mouthpiece 14 is provided at the bottom of the first perforation 23, and the plastic sleeve 15 is connected with th...

Abstract

The invention relates to the field of buildings, in particular to a U-shaped anchor cable recoverable in main rib and an application method thereof. The U-shaped anchor cable recoverable in working cable main rib comprises an anchor head and a casing pipe. The anchor head is composed of a shell cover and a bearing plate. A vertical column is fixed to the bearing plate. Two steel wire ropes are wound at the top of the vertical column. Supporting plates are symmetrically arranged at the two ends of the steel wire ropes. An anchor ring is fixed to each supporting plate. A working cable is installed on each anchor ring through a fixture. According to the U-shaped anchor cable recoverable in main rib and the application method thereof, the structure design is novel; one pair of working cables are symmetrically arranged; when the anchor cable works, the tensile forces of the two working cables are balanced and offset with each other; when main ribs are recovered, the working cables are loosened at first, when being tensioned, one of the working cables can be directly separated from a clamping piece, and then the other working cable is tensioned, so that the main ribs are recovered, and the pollution and influence on the surrounding underground environment are reduced; and the anchor cable of the structure is reliable and clear in stress, and the recovery process is convenient and efficient.

Description

technical field [0001] The invention relates to the field of construction, in particular to a recyclable U-shaped anchor cable for main reinforcement and a method for using the same. Background technique [0002] Since the early 1990s, my country has begun to use anchor cable support technology in large quantities in the reinforcement of deep foundation pits and slopes in urban buildings. section to provide greater pull-out resistance. The anchor cable is generally long, and the pull-out force is directly transmitted to the stable rock and soil layer at the far end through the steel strand and the anchor head. Due to the convenient construction and low cost of anchor cables, they are widely used in deep foundation pits of urban buildings. However, a large number of anchor cable materials such as steel bars and steel strands are permanently embedded in the ground, causing great difficulties to the surrounding follow-up engineering foundation construction. Therefore, develop...
