Embodiment Construction

[0035] In this embodiment, a kind of anchor cable of continuous basalt fiber composite reinforcement is as follows: figure 1 As shown, the anchor cable of a continuous basalt fiber composite reinforcement provided in this embodiment is composed of a plurality of continuous basalt fiber composite tendons 2 and a plurality of positioning centering devices 3 . The positioning centering device 3 connects the continuous basalt fiber composite tendons 2 scattered around the grouting pipe 1 and the grouting pipe 1 into a whole.

[0036] like figure 2 and image 3 As shown, the grouting pipe 1 of the anchor cable in this embodiment is evenly distributed on the pipe body of the anchor section with plum blossom-shaped grouting holes 1-1, and the head of the grouting pipe 1 to the flange 5 is embedded with a small-diameter anchoring grouting pipe 13 , the anchor slurry enters the inside of the flange 5 from the pipe to tightly connect the continuous basalt fiber composite tendon 2 and...

Abstract

The invention relates to an anchor cable made of a continuous basalt fiber composite rib material. The anchor cable comprises a grouting pipe (1), a steel strand (6), a prestress appplying anchor device, a continuous basalt fiber composite rib bundle (2), a flange connection structure and a PVC pipe (12). The anchor cable connects the continuous basalt fiber composite rib bundle with the steel strand together via the flange connection structure and the prestress appplying anchor device. The continuous basalt fiber composite rib bundle is installed in the PVC pipe by a plurality of uniformly distributed positioning centralizers (3). A section of anchoring slurry injection pipe is embedded in the grouting pipe, and anchoring slurry flows into the flange from the pipe to tightly connect the continuous basalt fiber composite rib bundle and the steel strand. The anchor cable made of the continuous basalt fiber composite rib material can replace steel strands, high-strength steel wires and the like to become a main tensile rib material; while tensile strength is met, lower shear strength is provided, and thus, residual anchor cable steel in the soil layer can be easily cut during later construction of surrounding projects.

Description

technical field [0001] The invention relates to an anchor cable of continuous basalt fiber composite reinforcement, which belongs to the technical field of civil engineering. Background technique [0002] With the development of the times, people's demand for underground space is increasing, thus increasing the construction of underground projects. Foundation pit support engineering is an important part of underground engineering. Usually, anchor cables can be used to reinforce the soil around the foundation pit. At present, most of the anchor cables used are steel bars and steel strands. The corrosion resistance of steel anchor cables is relatively poor, and additional anti-corrosion procedures are often required, and the construction is more complicated; moreover, the anchor cables are not easy to recycle, and are generally left in the soil layer. For the surrounding projects in the later stage, such obstacles are encountered during construction. , It is very inconvenient...
