Ground anchor safety technical requirements

1. The ground anchors used for hoisting should be made strictly according to the design, and concealed engineering records should be kept, and overloading is not allowed when using;

2. The ground anchor pit should be dug into a right-angled trapezoid shape, and the angle between the slope and the vertical should be 150 degrees. The anchor depth is determined according to the comprehensive situation of the site;

3. The angle between the drag rope and the horizontal plane is generally less than 30 degrees. The exit point of the ground anchor foundation pit (that is, the place where the wire rope passes through the soil layer and exposes the ground) is 2.5 times the depth of the front pit and within 2 meters on both sides of the foundation pit. No trenches, cables, underground pipelines and other structures, as well as temporary trenching, etc.;

4. No water should accumulate around the ground anchor;

5. Ground anchors are not allowed to be installed in the forward direction along the embedded parts
