Description

Technical Field

[0001] This utility model relates to the field of rock anchor construction, specifically to an integrated cable-lock rock anchor suitable for steep slope terrain. Background Technology

[0002] Traditional cable-stayed crane systems typically combine pylons, anchor towers, and rock anchors. This requires the installation of pylons and anchor towers, increasing material waste. Furthermore, traditional rock anchors use a one-to-one connection between the main cable and the prestressed anchor cable. If one anchor cable fails, the corresponding main cable loses its anchoring force, creating a significant safety hazard. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a cable-lock integrated rock anchor suitable for steep slope terrain. It mainly solves the following problems: (1) A special cross-section is adopted, and the stepped rock anchor fits the steep slope. A steel pipe is buried under the rock anchor and grouting is performed to ensure the stability of the rock anchor; (2) The main cable, working cable and arch bridge cleaving cable of the cable hoisting system are all arranged on the rock anchor, eliminating the cable tower and cleaving tower. At the same time, a groove is set at the cleaving cable pre-embedded hole as a cleaving cable tensioning operation platform to reduce material consumption and save costs; (3) The anchoring system composed of multi-layer and multi-row prestressed anchor cables bears the cable hoisting system and cleaving cable force as a whole, reducing the safety risk caused by the failure of a single prestressed anchor cable; (4) The prestressed anchor cables are arranged to spread out to both sides in the horizontal direction to increase the anchoring area and improve the stability and safety of the structure during construction.

[0004] This utility model is implemented as follows: a cable-locked integrated rock anchor suitable for steep slope terrain is constructed, characterized in that: the integrated rock anchor structure includes a stepped reinforced concrete foundation, a main cable anchor beam, a working cable pre-embedded part, a cable pre-embedded hole, and a prestressed anchor cable; this structure is designed specifically for the actual steep slope terrain, with a stepped reinforced concrete foundation, and then the main cable anchor beam, working cable pre-embedded part 3, and cable pre-embedded hole are arranged on the stepped reinforced concrete foundation, and a prestressed anchor cable is set at the upper end of the stepped reinforced concrete foundation.

[0005] According to the present invention, a cable-lock integrated rock anchor suitable for steep slope terrain is characterized in that: a main cable anchor beam is provided at the upper end of a stepped reinforced concrete foundation, and a drainage ditch is provided in the middle of the stepped reinforced concrete foundation.

[0006] According to the present invention, an integrated cable-lock rock anchor suitable for steep slope terrain is characterized in that: a pre-set groove at the pre-embedded hole of the cable serves as a tensioning operation platform, which greatly reduces the construction difficulty while ensuring the safety of construction.

[0007] According to the present invention, a cable-lock integrated rock anchor suitable for steep slope terrain is characterized in that: the stepped reinforced concrete foundation adopts a stepped cross-section, steel pipes are inserted and grouting is performed on the lower construction plane; steel bars are tied and concrete is poured in layers.

[0008] The present invention has the following advantages: (1) It adopts a stepped cross section form, which is suitable for steep slope terrain in mountainous areas; (2) Compared with the traditional cable crane, it sets up an integrated rock anchor with cable buckle, eliminates the independent cable tower buckle, reduces material consumption, and saves costs; (3) The four pre-embedded holes of the buckle are used as tensioning operation platforms, which greatly reduces the difficulty of construction while ensuring the safety of construction; (4) The anchoring system composed of multiple layers, multiple rows, and diffuse arrangement of multiple bundles of prestressed anchor cables bears the cable force of all cable strands and buckle cables of the cable crane as a whole, which reduces the construction safety risk and improves the stability and safety of the structure during construction.
