Description

Technical Field

[0001] The utility model relates to the technical field of assembled retaining walls, in particular to a PC hollow assembled retaining wall. Background Art

[0002] With the development of my country's construction infrastructure, the demand for retaining structures is increasing, especially in highway projects and water conservancy projects. Retaining walls play a key role in highway and water conservancy projects. They support roadbeds and riverbanks, prevent soil deformation and landslides, protect bridges, tunnels and other infrastructure, reduce floor space and stabilize the road surface. At the same time, retaining walls help control water flow and prevent soil erosion, ensuring project safety and stability. Most of the current retaining walls are solid settings. They are assembled and have low overall efficiency due to weight limitations. At the same time, rainwater easily accumulates on the retaining walls in rainy weather, which leads to erosion after long-term work, affecting the overall service life.

[0003] In response to the above problems, the inventors proposed a PC hollow assembled retaining wall to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a PC hollow assembled retaining wall.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a PC hollow assembled retaining wall, comprising a retaining wall body, the retaining wall body being composed of a first retaining block and a second retaining block arranged in an upper and lower manner, a storage trough being provided at the middle ends of the first retaining block and the second retaining block, two symmetrically arranged positioning blocks being fixed at one end of the top of the first retaining block, the positioning blocks being arranged in a semicircular shape, and a positioning groove corresponding to the positioning block on the first retaining plate being provided at the bottom of the second retaining block.

[0006] Preferably, grooves are provided at the upper and lower ends of the first retaining block and the second retaining block, and the grooves pass through the material storage troughs on the first retaining block and the second retaining block; two grooves are provided on the first retaining block and the second retaining block and are distributed at both ends.

[0007] Preferably, a decorative panel is installed at one end of the retaining wall body close to the positioning block.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] In the utility model, the retaining block is arranged to be hollow, which can firstly reduce its weight and increase the convenience of transportation and subsequent assembly, and at the same time play a role of water permeability. When water seeps into the retaining wall structure, the water can be discharged into the drainage pipe at the bottom through the gravel. At the same time, the positioning blocks and positioning grooves provided can make the spliced retaining blocks interlocked, and the matching grooves can make the gravel and the building blocks form an interlocking structure by filling the storage trough with gravel, thereby making the interlocking of the building blocks more secure.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Example: Figure 1-2 As shown, the utility model provides a PC hollow assembled retaining wall, including a retaining wall body 1, which is composed of a first retaining block 11 and a second retaining block 12 arranged in an upper and lower manner. This arrangement can make the retaining wall body 1 higher, and the purpose is also to be applied in situations where the retaining wall to be built is higher. A storage trough 13 is commonly provided at the middle end of the first retaining block 11 and the second retaining block 12, and two symmetrically arranged positioning blocks 14 are fixed at one end of the top of the first retaining block 11, and the positioning blocks 14 are arranged in a semicircular shape. The bottom of the second retaining block 12 is provided with a positioning groove 15 corresponding to the positioning block 14 on the first retaining plate.

[0016] The upper and lower ends of the first retaining block 11 and the second retaining block 12 are both provided with grooves 16, and the grooves 16 pass through the storage troughs 13 on the first retaining block 11 and the second retaining block 12; the grooves 16 are provided on the first retaining block 11 and the second retaining block 12 in two numbers and are distributed at both ends. The purpose of providing the two grooves 16 is to form an interlocking structure between the gravel and the blocks by filling the storage trough 13 with gravel during construction, thereby making the interlocking of the blocks more secure.

[0017] The retaining wall body 1 is provided with a decorative panel 2 at one end close to the positioning block 14. The decorative panel 2 is only for decoration. After the retaining wall bodies 1 are assembled one by one, some patterns can be designed on the decorative panel 2 to increase the aesthetics of the retaining wall body 1.

[0018] Working principle: First, for the installation of the retaining wall body 1, it can be stacked from the top at one time, and it can be docked and installed through the upper positioning block 14 and the lower positioning groove 15 to form an interlocking structure, making the overall structure more stable. When the hollow assembled retaining wall is installed, the inclination angle of the overall wall is 5 degrees. At the same time, the storage tank 13 set inside the retaining wall body 1 makes it hollow as a whole. The overall hollow structure is adopted. One purpose is to reduce the use of overall concrete. The second purpose is to add gravel inside the storage tank 13. During construction, after placing the PC hollow assembled retaining wall blocks, by filling gravel in the hollow part, the overall weight can be made heavier, and the weight is almost the same as that of the solid concrete structure as a whole, thereby reducing gravity during assembly, improving the convenience of transportation and subsequent assembly, and at the same time playing a water-permeable role. When water seeps into the retaining wall structure, the water can be discharged into the drainage pipe at the bottom through the gravel.

[0019] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
