Ground Anchor For Slope Protection

Ground anchor for slope protection:

The utility model relates to the technical field of slope protection, in particular to a ground anchor structure for slope protection which has an automatic clamping structure.

Background technology: Engineering slope protection has two types of slope protection and retaining structure protection, slope protection measures commonly used are mortar or sanhejie plaster, grouting, shotcrete, grouting stone parapet, shotcrete slope protection, shotcrete net slope protection, such measures are mainly used to protect the excavation side slope of rock weathering and peeling, fragmentation and a small amount of rock falling blocks and other phenomena, the protected slope, There should be enough stability, and the unstable slope should be supported and protected first. In slope protection construction, often use the ground anchor structure and anchor net way for slope support operations, now commonly used anchor bolt fixing means is to use drill drilling, and then the anchor bolt into the drilling hole, and then use the anchor bolt fixed nut anchor net fixed, and then in the anchor net outside the spray concrete, the use of a whole block of concrete wall to achieve slope protection, existing support installation operations, In order to improve the efficiency of bolt installation and avoid repeated dressing of the size of the hole, the size of the hole is often determined according to the diameter of the bolt. However, due to the varying degree of softness of the soil in various places, the size of the hole is often not consistent with the diameter of the bolt. Too soft soil will make the hole shrink, which makes the installation of the bolt more difficult, and the hard soil will make the hole expand. The contact between the bolt and the soil is too loose, which reduces the fixing degree of the bolt and affects the supporting effect. Therefore, it is necessary to provide a new ground anchor structure for slope protection with automatic clamping structure to solve the technical problems mentioned above. Technical implementation elements: In order to solve the above technical problems, the utility model provides a ground anchor structure for slope protection with automatic clamping structure, which can make the pile driving and the borehole forming expansion extrusion at the same time to improve the adaptability of anchor rod installation.
