Embodiment Construction

[0028] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings of the specification, and specific implementation manners will be given.

[0029] Such as figure 1 , figure 2 , image 3 A U-shaped anchor cable is shown for the main reinforcement of a working cable, and the U-shaped anchor cable includes an anchor head 1 and a plastic sleeve 15. The anchor head 1 includes a shell cover 6, a bearing bottom plate 12, and a column 2. The bearing bottom plate 12 closes the bottom of the shell cover 6. The column 2 is arranged in the middle of the bearing bottom plate 12, and the bearing bottom plate 12 at the bottom of the column 2 is respectively provided with The first perforation 23 for the working rope 13 to pass through is provided with a set of clamping devices for clamping the working rope 13 above the first perforation 23; the bottom of the first perforation 23 is provided with an interface tube 14 and the plastic sleeve...

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 use method thereof. Background technique [0002] Since the early 1990s, my country has begun to use anchor cable support technology extensively in the reinforcement of deep foundation pits and slopes of urban buildings. The anchor cable is installed in the remote stable rock and soil layer by setting a certain length of free section at the proximal end. Segment to provide greater pull resistance. The anchor cable is generally long in length, and the pull-out force is directly transmitted to the remote stable rock and soil layer through the steel strand and the anchor head. Because of its convenient construction and low cost, the anchor cable is widely used in deep foundation pits of urban construction. However, a large number of anchor materials such as steel bars and steel strands are permanently buried in the ground, causi...
