[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 As shown, a soil nail wall support structure includes a soil slope body 1, a fixing rod 2, an end 3 and a concrete layer 4.

[0029] like Figure 1 、 Figure 2 As shown, the slope surface of the earth slope body 1 is provided with multiple rows of mounting holes 5, and the fixing rods 2 are inserted into the mounting holes 5. The end 3 is threadedly connected to the fixing rod 2 and presses the slope surface of the earth slope body 1. The concrete layer 4 is provided on the slope surface of the earth slope body 1.

[0030] like Figure 2 、 Figure 3 As shown, the side wall of the fixing rod 2 is provided with multiple layers of barbs 21, which are inclined toward the end of the fixing rod 2, and the outer wall of the fixing rod 2 is provided with multiple circles of reinforcement rings 22, which are fixed to each layer of barbs 21.

[0031] Therefore, by setting a fixing rod 2 with barbs 21 to penetrate into the soil slope body 1, after the concrete pouring is completed, it can be integrated with the concrete, and at the same time, the reverse tensile force of the fixing rod 2 can be increased to prevent the fixing rod 2 from moving, and at the same time increase the stability of the entire soil nail wall support structure.

[0032] like Figure 3 、 Figure 4 As shown, a reinforcement 6 is provided at the tail end of the fixing rod 2, and the reinforcement 6 includes a tube body 61, a plate body 62 and a driving mechanism 63. The tube body 61 is threadedly connected to the lower end of the rod body of the fixing rod 2, and the upper end of the plate body 62 is rotatably connected to the lower end of the tube body 61. The driving mechanism 63 is used to control the lower end of the plate body 62 to flip outward.

[0033] like Figure 3 、 Figure 4As shown, the driving mechanism 63 includes a driving rod 64, a driving tube 65 and a push rod 66. The driving rod 64 is vertically arranged in the tube body 61, and the driving tube 65 is vertically slidably connected to the driving rod 64, and the lower end is lower than the lower end of the plate body 62. One end of the push rod 66 is rotatably connected to the outer wall of the driving tube 65, and the other end is tilted upward and rotatably connected to the inner wall of the lower end of the plate body 62.

[0034] When installing the fixing rod 2, as the fixing rod 2 gradually extends downward, the driving tube 65 will contact the bottom wall of the mounting hole 5, and during the continuous descent of the fixing rod 2, the driving tube 65 will slide upward and control the push rod 66 to move synchronously. At this time, the push rod 66 drives the lower end of the plate body 62 to automatically flip outward, thereby realizing the automatic opening of the reinforcement 6.

[0035] Therefore, after pouring, the outward-expanded plate 62 can form an anti-floating node in the opposite direction at the bottom position of the fixed rod 2 to resist the buoyancy and surge force of the groundwater, increase the overall structural strength and anti-floating ability of the fixed rod 2, and ensure the stability of the structure.

[0036] like Figure 2 、 Figure 5 As shown, a steel mesh 7 is provided in the concrete layer 4, and the upper end of the steel mesh 7 is bent and extended to the upper end surface of the slope body 1. The upper end of the concrete layer 4 covers the upper end of the steel mesh 7 to increase the stability of the concrete layer 4 and prevent the concrete layer 4 from cracking.

[0037] like Figure 2 、 Figure 5 As shown, the upper end of the steel mesh 7 is vertically and spaced apart with a plurality of dowel bars 8 inserted into the slope body 1, which increases the stability of the steel mesh 7 and ensures the structural strength and stability of the concrete layer 4. The lower end of the dowel bar 8 is bent and provided with a hook 81 for hooking the uppermost fixing rod 2, so as to be mutually tied with the fixing rod 2 to increase the structural strength and stability.

After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
