Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a slope protection device for soil nail wall construction. Background Technique

[0002] The slope protection device for soil nail wall construction is a special supporting structure for strengthening slopes. It enhances the stability of the slope by setting soil nails made of steel bars in the foundation pit slope. These soil nails are closely combined with the surrounding soil to form a composite body, effectively resisting the erosion of external forces on the slope. At the same time, a steel mesh is laid on the slope surface and a layer of concrete surface layer is sprayed, further enhancing the overall strength and stability of the slope. This slope protection device not only has the advantages of stable and reliable, simple construction and short construction period, but also performs outstandingly in terms of economy and effect. Especially in areas with good soil quality, the application effect of the slope protection device for soil nail wall construction is particularly remarkable, which can ensure the stability of the slope surface after the foundation pit excavation and effectively prevent safety accidents such as landslides and collapses.

[0003] At present, when installing and protecting the soil nail wall for slope protection, generally, anchor rods are inserted into the inside of the soil nail wall to reinforce it and improve its stability. Although the anchor rods can provide a certain amount of tensile force, in the face of complex and changeable soil conditions or external loads, relying solely on the anchor rods for fixation may not guarantee the overall stability of the soil nail wall and the slope protection. Therefore, a slope protection device for soil nail wall construction is proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-3 , a slope protection device for soil nail wall construction in this embodiment, includes a soil nail wall 1 and a slope protection 2, and a reinforcement mechanism is provided on the outer wall of the soil nail wall 1.

[0021] The slope protection 2 is installed on the outer wall of the soil nail wall 1 and has a shape adapted to it.

[0022] The reinforcement mechanism includes two anchor rods 3 fixedly installed on the outer wall of the bottom of the slope protection 2, and two barbs 4 fixedly installed on the outer peripheral wall of the anchor rods 3. Both the anchor rods 3 and the barbs 4 are installed inside the soil nail wall 1. The bottom of the anchor rod 3 is conical. Two mounting plates 5 are movably installed on the top of the soil nail wall 1. Two first screws 6 are movably installed inside the mounting plates 5. Four first threaded grooves are provided on the top of the soil nail wall 1. The first screws 6 pass through the inside of the mounting plates 5 and are threadedly connected to the inside of the first threaded grooves and are of suitable size.

[0023] A fixing rod 7 is fixedly installed on the top of the mounting plate 5. A fixing plate 8 is fixedly installed on the side of the fixing rod 7 close to the slope protection 2. Two reinforcement limiting seats 9 are fixedly installed on the bottom of the fixing plate 8. The slope protection 2 is located between the two mounting plates 5. The fixing plate 8 is located directly above the slope protection 2. The reinforcement limiting seat 9 is T-shaped, and the side of the reinforcement limiting seat 9 away from the fixing plate 8 is attached to the top outer wall of the slope protection 2.

[0024] A reinforcement pile 10 is fixedly installed at the top of the soil nailing wall 1. An installation seat 11 is movably installed on the left side of the reinforcement pile 10. Two second screws 12 are movably installed inside the installation seat 11. Two second threaded grooves are formed on the left side of the reinforcement pile 10. After the second screws 12 penetrate through the inside of the installation seat 11, they are threadedly connected to the inside of the second threaded grooves and are of suitable size.

[0025] One side of the reinforcement plate 14 away from the installation seat 11 is attached to the inclined outer wall of the slope protection 2. A support plate 13 is fixedly installed on the left outer wall of the installation seat 11. A reinforcement plate 14 is fixedly installed on the left outer wall of the support plate 13. A support rod 15 is fixedly installed on the top of the right fixing plate 8. A support seat 16 is fixedly installed on the top of the support rod 15. The support seat 16 is U-shaped.

At this time, the fixing plate 8 is located on the top of the slope protection 2 and the reinforcement limiting seat 9 is attached to the top of the slope protection 2 to carry out limit protection on it. Then slide the support plate 13 and the installation seat 11 from top to bottom, so that the installation seat 11 slides on the left side of the reinforcement pile 10, and the support plate 13 is clamped into the support seat 16. At this time, the left outer wall of the reinforcement plate 14 will be attached to the inclined surface of the slope protection 2. Finally, penetrate the second screws 12 through the inside of the installation seat 11 and then threadedly connect them to the inside of the reinforcement pile 10. At this time, the reinforcement work on the slope protection 2 is completed.
