Description

TECHNICAL FIELD

[0001] The present application relates to the field of slope reinforcement, and particularly discloses an anchor cable stress adjusting system in a slope reinforcement system. BACKGROUND

[0002] Slope reinforcement refers to artificially reinforcing and stabilizing a slope to prevent the slope from causing road safety hazards such as landslides and slippage. There are many slope reinforcement methods in the prior art, such as grouting reinforcement, anchor rod reinforcement, and prestressed anchor cable reinforcement. Grouting reinforcement reinforces soil layer structures by injecting mortar into the soil layer to prevent landslides caused by softening of the soil layer. Anchor rod reinforcement fixes the concrete structure on the surface of the slope by using anchor rods. Prestressed anchor cable reinforcement tightens the concrete structure on the surface of the slope to ensure the reinforcing effect of the concrete structure on the slope. The prestressed anchor cable is reliable in stress and has little damage to the slope, and is therefore widely used. However, the prestress is lost after the anchor cable is used for a period of time, and how to compensate for the loss is a technical problem that needs to be solved. SUMMARY

[0003] In view of this, the present application aims to provide an anchor cable stress adjusting system in a slope reinforcement system to solve the technical problem of how to compensate for the stress of the anchor cable.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0016] S2, the adjusting cable drives the adjusting seat to move upward, the adjusting seat drives the cable to move upward, the cable can drive the third end seat to move downward after passing through the adjusting pulley, and the winding device is stopped after the third end seat moves downward by a distance;

[0017] S3, the opening at the upper end of the adjusting sleeve is sealed with quick-drying cement, and the quick-drying cement is waited to solidify;

[0018] S4, an external concrete pouring pipe is connected with the communication interface of the adjusting sleeve, and then concrete is poured into the communication interface, the concrete enters the body of the anchor head from the communication hole at the bottom of the adjusting sleeve after entering the adjusting sleeve, the communication interface is sealed after pouring is completed, and the concrete is solidified and shaped; according to the situation, the winding device can be immediately withdrawn after pouring is completed, or the winding device can be withdrawn after the concrete is solidified.

[0019] The working principle and beneficial effects of the scheme are:

[0020] In the scheme, the third end seat is pulled downward by the adjusting seat and the adjusting cable to pull the anchor cable body downward, so as to supplement the lost stress and make the anchoring effect of the anchor cable body not lost. After the stress of the anchor cable body is adjusted in the scheme, concrete needs to be poured into the adjusting sleeve, so the anchor cable stress adjusting system of the scheme can only be adjusted once.
