Description

Technical Field

[0001] This utility model belongs to the field of foundation pit support technology, and in particular relates to a geotechnical engineering slope anchoring support structure. Background Technology

[0002] Geotechnical engineering includes foundations, slopes, and underground engineering. In geotechnical engineering construction, foundation pit support is a crucial part of the construction process. Foundation pit support in geotechnical engineering involves measures to support, reinforce, and protect the sidewalls and surrounding environment of the foundation pit to ensure the safety of underground structure construction and the surrounding environment. A search revealed that patent CN221118505U discloses a foundation pit anti-collapse support structure for geotechnical engineering, comprising: a base plate anchored to the bottom of the foundation pit; a base bolted to the base plate; a support assembly rotatably connected to the base, the support assembly including multiple support rods, with adjacent vertical support rods rotatably connected; a limiting member for locking the rotation angle of the support rods; a top plate anchored to the top of the foundation pit; a traction mechanism connecting the top plate and the limiting member; and a protective plate bolted to the sidewalls of the support rods, the protective plate fitting against the foundation pit slope.

[0003] However, in actual use, the applicant found that the connection between two adjacent support rods was not convenient enough, making it difficult for personnel to quickly adjust the length of the support rods according to the slope length. At the same time, due to the unevenness of the slope surface, it was difficult to ensure that the connecting plates on the two adjacent support rods were on the same plane, making it impossible to smoothly install and fix the protective plate on the connecting plate of the two adjacent support rods, thus failing to achieve the anchoring support of the geotechnical engineering slope. In view of this, we propose a geotechnical engineering slope anchoring support structure. Utility Model Content

The connections between the upper limit steel cable 3 and the middle steel cable 4, between the middle steel cable 4 and the lower limit steel cable 5, and between the two middle steel cables 4, are secured because the anchoring steel cable 1 is close to the ground and under the limiting and pulling action of the tension support 8 and the slope protection net 2, they will not... In the event of significant rotation causing the connection to detach, a tension support 8 is fixedly attached to the middle steel cable 4. At least two middle steel cables 4 are provided on the tension support 8. Bolts 81 that cooperate with anti-loosening nuts 9 are symmetrically fixed on the top of the tension support 8.

Next, use the second anchor rod 7 to fix the lower end of the lower limit steel cable 5 to the soil at the bottom of the slope. After tightening the anchor cable 1, use the first anchor rod 6 to fix the upper end of the upper limit steel cable 3 to the soil above the slope. Repeat the above operations along both sides of the slope, using appropriate... Several anchoring steel cables 1 are laid out in parallel at intervals. Then, the slope protection net 2 is placed between two adjacent anchoring steel cables 1, and the connecting supports 21 on both sides of the slope protection net 2 are hooked onto the bolts 81 on the corresponding tension supports 8.
