[0021] To address the issue that existing anchor cables, when subjected to inclined traction, cannot adaptively adjust the connection between the support structure and the anchor cable at the ground section according to the angle and direction of inclination, leading to wear and tear during long-term use; please refer to... Figure 1-3 The present invention provides the following solution:

[0022] Reference Figure 1 A novel high-strength and high-toughness anchor cable support structure includes an anchor support frame 1, a locking sleeve 2 is provided on the top of the anchor support frame 1, the locking sleeve 2 is welded to the anchor support frame 1, wherein an adjusting shaft seat 3 is provided on the inner side of the locking sleeve 2, the anchor support frame 1 includes a top support plate 101 and a bottom support plate 102, the top support plate 101 and the bottom support plate 102 are connected by a bracket, and an integrally formed inner support ring 105 is provided on the surface of both the top support plate 101 and the bottom support plate 102;

[0023] In this embodiment, the top support plate 101 and the bottom support plate 102 adopt a design that is narrower at the top and wider at the bottom, which can improve the compressive support of the anchor support frame 1. The bottom support plate 102 is installed and used with the foundation pit slope, and then the anchor cable is inserted from the inside of the anchor support frame 1 into the anchoring section inside the foundation pit.

[0024] Reference Figure 1-2 The anchor support frame 1 is provided with a cable tube 104 inside. The two ends of the cable tube 104 extend to the inner side of the inner support ring 105 on the surface of the top support plate 101 and the bottom support plate 102, respectively. Eight torque springs 106 are provided between the two ends of the cable tube 104 and the inner support ring 105. The torque springs 106 are arranged in a ring. The two ends of the torque springs 106 are welded to the cable tube 104 and the inner support ring 105.

[0025] In this embodiment, the cable tube 104 is located between the top support plate 101 and the bottom support plate 102. The anchor cable needs to pass through the inside of the cable tube 104 and then be adjusted according to the installation angle of the anchor cable. When adjusting the angle, the torque springs 106 at both ends of the cable tube 104 can assist the cable tube 104 in fixing the angle deflection. While playing a supporting role, the torque springs 106 can also effectively absorb the force generated by the polarization of the anchor cable, avoiding excessive friction between the anchor cable and the cable tube 104.

Then, the anchor cable is inserted from the inside of the anchor support frame 1 into the anchoring section inside the foundation pit. The anchor cable needs to pass through the inside of the cable tube 104. Then, it is adjusted according to the installation angle of the anchor cable. When adjusting the angle, the torque springs 106 at both ends of the cable tube 104 can assist the cable tube 104 in fixing the angle deflection. The torque springs 106 can not only provide support, but also effectively absorb the force generated by the polarization of the anchor cable, avoiding excessive friction between the anchor cable and the cable tube 104. The adjusting shaft seat 3 is installed inside the locking sleeve 2. The anchor cable also needs to pass through the inside of the adjusting shaft seat 3. Moving the adjusting shaft seat 3 can control the direction and angle of the anchor cable. After the adjusting shaft seat 3 is adjusted, the top rod 201 on the outside of the locking sleeve 2 is tightened, and the locking head 203 at one end is attached to the anti-slip groove 302 on the surface of the adjusting shaft seat 3. In this way, the adjusting shaft seat 3 can be locked and fixed by the top rod 201 to prevent the anchor cable position from shifting.
