step S611: adjusting the adjustable base to enable the upright to be at a preset height;
step S612: two sweeping rods above the adjustable base are fixed together with the extending section of the slope anchor rod below by using fixed steel wires.
In this embodiment, after the height of the upright rod 31 of the second bracket on the extension section of the slope anchor rod 40 is adjusted in place by adopting the adjustable base screw, 2 sweeping rods (longitudinal or transverse) above the adjustable base screw and the extension section of the lower horizontal anchor rod can be fixed for 1 channel by adopting the double-strand 8# galvanized steel wire conforming to the general purpose low carbon steel wire (YB/T5294), so that the slope anchor rod 40 is firmly fixed.
In actual construction, the method can be applied to the position of the scarp at the outlet of the Gong beach tunnel of the first-term engineering of the unitary highway from Peng Shui to the unitary highway, dangerous rock bodies are arranged on the scarp part, the scarp is in an understable state, and under the influence of adverse factors such as storm, vibration and the like, the whole dumping damage is likely to happen, and if the new dangerous rock bodies are further developed, the new dangerous rock bodies are formed. To ensure the overall stability of the cliff rock wall, reinforcement and protection of the cliff rock wall is therefore required. First, a bracket needs to be erected so that workers can stand on the scaffold to reinforce and protect the cliff wall. However, the height of the scarp at the place reaches 190m, the coverage width is 85.5m, the gradient is close to 90 degrees, the traditional construction support is difficult to erect on the scarp of hundreds of meters, and potential safety hazards such as instability and the like are easy to exist after the construction support is erected. In the technical scheme of the invention, the foundation platform comprises multiple steps, can adapt to the complex environment at the scarp slope feet and provides stable support for the upper support. The cantilever support is anchored on the cliff and is tightly connected with the cliff wall, so that a stable working environment is provided for constructors. The cantilever support structure is stable, so that the construction environment is safer and more stable. The second stage support is erected on the cantilever frame and separated from the first stage support structure, and the stress is relatively independent. The first-stage support and the second-stage support are structurally separated, and are relatively independent in stress, so that the burden of the second-stage support cannot be increased due to the arrangement of the second-stage support, and the second-stage support is safer. And, the construction process is carried out, the first-stage bracket can be dismantled, and the construction of the upper-stage bracket can not be influenced. The satisfactory material of the first stage scaffold is then used to set up the upper scaffold. Saving building materials, realizing recycling of materials and reducing cost. The slope anchor rod anchored on the cliff wall is used for further supporting the second-stage support, so that the construction support can be better and more stably fixed on the cliff wall, a stable construction environment is provided for workers, and construction safety is guaranteed.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
