DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] like Figure 1-5 As shown, the utility model provides an assembled retaining wall, comprising a plurality of layers of box assemblies, wherein the upper and lower layers of box assemblies are spliced by a splicing portion, and each layer of box assemblies comprises a plurality of boxes 1, and the side walls of the boxes 1 are provided with transverse fixing teeth 4, and the transverse fixing teeth 4 on the left and right adjacent boxes 1 are engaged with each other, and the upper and lower end surfaces of the boxes 1 are spliced by anti-dislocation components;
[0029] The splicing part includes a vertical fixed pile body through hole 3 opened in the center of the bottom surface of the box body 1, and the left and right top surfaces of the box body 1 are fixedly connected with symmetrically arranged vertical fixed pile bodies 2. The vertical fixed pile bodies 2 are semi-cylindrical structures. Adjacent vertical fixed pile bodies 2 are inserted into the vertical fixed pile body through holes 3 of the box body 1 located on the upper layer, and the bottom surface of the box body 1 located at the bottom is detachably connected with a fixed part.
[0030] When the utility model is in use, a plurality of boxes 1 are arranged in sequence and installed above the fixing part, and the horizontal fixing teeth 4 between the adjacent boxes 1 after splicing are meshed with each other to prevent the boxes 1 from shifting in the vertical direction, and the vertical fixing piles 2 are inserted into the vertical fixing pile through holes 3 of the box above to fix the two adjacent boxes 1 on the left and right to prevent their shifting. In addition, by arranging anti-shifting components on the upper and lower sides of the boxes 1, the boxes 1 between the two layers can be prevented from shifting under the action of earth pressure. The retaining wall can be assembled by assembling, and when the wall is damaged, it can be replaced separately, so the retaining wall can be repaired, and the service life of the retaining wall can be effectively extended.
[0031] According to a further optimized solution, the vertical fixing piles 2 of the two adjacent boxes 1 on the left and right are assembled into a cylindrical structure, and the cylindrical structure is inserted into the vertical fixing pile through hole 3 of the box 1 located on the upper layer.
[0032] By arranging the vertical fixing pile body 2 to be inserted into the vertical fixing pile body through hole 3 , the disassembly and assembly of the boxes 1 can be facilitated.
[0033] According to a further optimized solution, the arc-shaped side wall of the vertical fixed pile body 2 is provided with a thread, and nuts are threadedly connected to the outer sides of two adjacent vertical fixed pile bodies 2 , and the nuts abut against the inner bottom wall of the box body 1 .
[0034] By providing the nuts, the two vertical fixing piles 2 can be fastened, and the box body 1 between the upper and lower layers can be installed and disassembled.
[0035] In a further optimized solution, the transverse fixing teeth 4 include protrusions and grooves, and the protrusions match the grooves of adjacent boxes 1. By providing the transverse fixing teeth 4 and engaging the fixing teeth between two adjacent boxes 1, misalignment between the boxes 1 between the upper and lower layers can be prevented.
[0036] According to a further optimized solution, four water leakage holes 6 are provided at the bottom of the box body 1 , and the four water leakage holes 6 are arranged at equal intervals along the circumference of the vertical fixed pile body through hole 3 .
[0037] When rain occurs, the water in the upper box body 1 can be discharged into the lower box body 1 through the water leakage hole 6 by setting the water leakage hole 6.
[0038] According to a further optimization scheme, a side of the box body 1 close to the soil is fixedly connected with a transverse fixed pile body 7, and an end of the transverse fixed pile body 7 away from the box body 1 is fixedly connected with a frustum, and the small end of the frustum is arranged away from the box body 1.
[0039] After the retaining wall is used, the transverse fixed pile body 7 is pressed into the earth, and the earth exerts a downward pressure on the transverse fixed pile body 7. At the same time, due to the effect of the cone, when the retaining wall tilts outward, the existence of the cone generates an interaction force with the earth, which can prevent the box body 1 from moving outward.
[0040] In a further optimized solution, the anti-dislocation component includes a first beveled tooth 5 provided on the top surface of the box body 1 and a second beveled tooth 11 provided on the bottom surface of the box body 1, and the upper and lower adjacent boxes 1 are matched with each other through the first beveled tooth 5 and the second beveled tooth 11. By setting the first beveled tooth 5 and the second beveled tooth 11 to match, it can be ensured that the interaction force between the boxes 1 between the upper and lower layers is directed toward the earthwork direction, thereby ensuring the blocking force of the retaining wall.
[0041] According to a further optimized solution, the fixing part includes a base 8 and a vertical steel bar 9 arranged on the base 8. The vertical steel bar 9 is correspondingly passed through the leakage hole 6. The vertical steel bar 9 is threaded with a steel bar nut, and the steel bar nut abuts against the bottom surface of the inner wall of the box body 1.
[0042] The bottom box 1 is locked on the base 8 by the cooperation of the vertical steel bars 9 and the steel bar nuts, so as to ensure the stability of the fixing of the box 1.
[0043] In a further optimized solution, the box body 1 at the bottom is located on the base 8, and the top surface of the base 8 is provided with a third bevel tooth 12, which cooperates with the second bevel tooth 11. The mutual cooperation between the third bevel tooth 12 and the second bevel tooth 11 can make the reverse force of the box body 1 on the earthwork in the direction of the earthwork, thereby ensuring the stability of the retaining wall.
[0044] To further optimize the solution, a plurality of drainage grooves 10 are provided on the top surface of the base 8 , and the ends of the drainage grooves 10 away from the soil penetrate the side walls of the base 8 , and the drainage grooves 10 correspond to the leakage holes 6 .
[0045] By providing the drainage groove 10, the water accumulated in the upper box 1 can be discharged through the drainage groove 10 to prevent it from entering the earthwork, thereby avoiding the settlement of the earthwork and effectively protecting the earthwork.
[0046] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
