Description

[0002] In the field of rock and soil anchoring engineering, the application of prestressed anchor cable is very wide. In the early stage, when grouting the anchor cable, there is no special temporary plugging device, and simple materials such as cotton yarn and cloth strips are often used to plug the anchor cable orifice. This way has poor plugging effect. During the grouting process, due to the action of grouting pressure, the slurry is easy to seep out of the orifice, resulting in insufficient grouting, which further affects the anchoring effect of the anchor cable. Moreover, these materials are easy to be left in the hole, polluting the hole, and are not conducive to subsequent construction. With the development of engineering technology, the requirement for the quality of anchor cable grouting is getting higher and higher. Some plugging methods use clay and other materials, which can improve the plugging condition to some extent, but clay may soften after being wetted, and it is still difficult to ensure good plugging effect under continuous grouting pressure. Moreover, under complex geological conditions, such as broken rock stratum or areas rich in underground water, the traditional plugging method is more difficult to meet the requirements. In order to solve these problems, the prestressed anchor cable grouting temporary plugging device emerges as the times require. It can effectively resist the grouting pressure, prevent the slurry from leaking, ensure full grouting, and thus improve the overall performance of the anchor cable. Moreover, it is convenient to install and disassemble, and can adapt to different anchor cable sizes and complex construction environments.
