Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an anchor cable supporting and blocking device. Background Art

[0002] As mining depths continue to increase at the Jinchuan Mine, high ground stress and increased ground pressure are becoming increasingly severe. For large spans and fractured areas, long anchor cable support is a relatively effective reinforcement measure. Sealing holes is essential for long anchor cable construction, preventing grout leakage and ensuring safety and stability.

[0003] Cement and resin rolls are commonly used underground to seal long anchor cable openings. Cement rolls require waiting for the cement to solidify (generally 24 hours) before grouting can begin; resin rolls require waiting for the resin anchor to harden before grouting can begin. This results in a lengthy construction process and compromises efficiency. Furthermore, cement and resin rolls cannot be reused, resulting in waste. Utility Model Content

[0004] The purpose of the utility model is to provide an anchor cable support and plugging device, which can shorten the construction time, improve the construction efficiency and avoid material waste.

[0005] To achieve the above-mentioned purpose, the first aspect of the present invention provides an anchor cable support and sealing device, including a first main pipe, an end cover is installed at one end of the first main pipe, the end cover is closed and connected to the first main pipe, a first branch pipe is provided on the side wall of the first main pipe, one end of the first branch pipe is fixedly connected to the first main pipe, the inner hole of the first main pipe is connected to the inner hole of the first branch pipe, and the intersection of the first main pipe and the first branch pipe is sealed and connected.

[0006] The second aspect of the utility model also provides an anchor cable support and sealing device, including a second main pipe, one end of which is equipped with an end cover, and the end cover is closed and connected to the second main pipe; the other end of the second main pipe is fixedly connected to a connecting pipe through a three-way joint, and the connecting pipe and the second main pipe are coaxially arranged. The other port of the three-way joint is equipped with a second branch pipe, and the inner hole of the second branch pipe, the inner hole of the connecting pipe and the inner hole of the second main pipe are connected.

[0007] The utility model relates to an anchor cable support and plugging device which can replace cement medicine rolls and resin medicine rolls to plug the long anchor cable holes, can be reused to reduce material waste, and can realize grouting while plugging to improve construction efficiency.
