[0014] III) Beneficial effects

[0015] Compared with the existing technology, the pressure-dispersed anchor cable for slope management has the following beneficial effects:

[0016] 1. The utility model is provided with a plug. When the anchor cable is installed, the annular tube is connected to the outer end through a mechanical device and pulled outward, so that the annular tube will pull the transmission tube, the guide tube and the plug to move outward. When the plug is pulled backward, its pointed end will be inserted into the soil, generating a force with the soil. At this time, the flexible tube will bend, so that the plug can be almost vertical to the guide tube, and all the plugs are almost in the same plane. At this time, soil solidifier is injected into the annular tube through the feeding tube, and the soil solidifier is pressurized to reach the plug through the transmission tube and the flexible tube, and then discharged from the discharge hole into the soil around the plug, so as to solidify the soil in the shallow layer of the slope over a large area, making it difficult to loosen and lose, thereby solving the problem that the existing pressure-dispersed anchor cable for slope management cannot fix the soil in the shallow layer of the slope, so that the slope is still prone to sliding and losing.

[0017] 2. The utility model is provided with a first connecting ring at the side end of the transmission pipe and a second connecting ring at the other end. When the soil solidifying agent is injected, the annular pipe is removed by rotating the second connecting ring, and then each transmission pipe is rotated separately to separate it from the conduit. In this way, the transmission pipe can be pulled out of the device and can be recycled after cleaning. In this way, it will not hinder the subsequent pouring of the grouting pipe and also reduce the cost of construction materials. BRIEF DESCRIPTION OF THE DRAWINGS
