Description

Technical Field

[0001] This utility model belongs to the field of foundation pit construction, and specifically relates to a recyclable protection device for retaining walls. Background Technology

[0002] For open-cut subway stations in urban areas, a concrete retaining wall with a height of no less than 0.5m needs to be set up along the upper edge of the foundation pit. Due to the need for excavation, the retaining wall is usually left with an opening 5 meters wide. After the excavation is completed, the opening is re-poured with concrete to restore the retaining wall. Since the inside of the foundation pit is suspended at this time, there are safety and quality hazards in the formwork installation and concrete pouring, which can easily cause people to fall and suffer injuries or fatalities. In view of this situation, a simple protective device is needed at the opening of the retaining wall. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a recyclable protection device for retaining walls.

[0004] This invention is achieved through the following technical solution:

[0005] A recyclable retaining wall protection device includes several inverted U-shaped protective plates. The inner width of the inverted U-shaped protective plate is equal to the thickness of the retaining wall, and the height of the inverted U-shaped protective plate is less than the height of the retaining wall but greater than the opening height. Connecting strips are provided vertically outward on the front, rear, left and right sides of the inverted U-shaped protective plates. The connecting strips are provided with screw holes. Adjacent inverted U-shaped protective plates are fixed together by bolts passing through the screw holes. Handles are provided on the sides of the inverted U-shaped protective plates, and round holes are provided at the bottom of the inverted U-shaped protective plates.

[0006] Preferably, each section of the inverted U-shaped protective plate is 2m long.

[0007] Preferably, the inverted U-shaped protective plate is welded from steel plate with a thickness of 5mm.

[0008] The recyclable retaining wall protection device of the present invention is simple to manufacture, low in cost, lightweight, can be transported manually, and is quick to assemble and disassemble. It is suitable for the protection of open retaining walls of different lengths, avoids construction safety hazards, can be reused, and reduces protection costs. Attached Figure Description

[0011] Figure 3 This is a schematic diagram of the open structure of the retaining wall in this embodiment.

[0012] In the diagram, 1 is an inverted U-shaped protective plate, 2 is a retaining wall, 3 is an opening, 4 is a connecting strip, 5 is a screw hole, 6 is a bolt, 7 is a handle, and 8 is a round hole. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0014] This embodiment includes several sections of inverted U-shaped protective plates 1. Each inverted U-shaped protective plate 1 is formed by welding 5mm thick steel plates, and each section is 2m long. The inner width of the inverted U-shaped protective plate 1 is equal to the thickness of the retaining wall 2, meaning the inverted U-shaped protective plate 1 can just fit onto the retaining wall 2. The height of the inverted U-shaped protective plate 1 is less than the height of the retaining wall 2 but greater than the height of the opening 3. This means that after the inverted U-shaped protective plate 1 is fitted onto the retaining wall 2, its bottom does not reach the bottom of the retaining wall 2, but its bottom is located below the bottom of the opening 3, creating a junction area between the inverted U-shaped protective plate 1 and the retaining wall 2 below the opening 3. A circular hole 8 is provided at the bottom of the inverted U-shaped protective plate 1, located in the junction area between the inverted U-shaped protective plate 1 and the retaining wall 2 below the opening 3. Expansion bolts are driven into the retaining wall 2 through the circular hole 8 to fix the inverted U-shaped protective plate 1 to the retaining wall 2. Connecting strips 4 are provided vertically outward on both the left and right sides of the front and rear ends of the inverted U-shaped protective plate 1. The connecting strips 4 are provided with screw holes 5. Adjacent inverted U-shaped protective plates 1 are fixed together by bolts 6 passing through the screw holes 5. To facilitate the handling of the inverted U-shaped protective plate 1, handles 7 are provided on the side of the inverted U-shaped protective plate 1. Workers can move the inverted U-shaped protective plate 1 by holding the handles 7.

[0015] In use, select the number of inverted U-shaped protective plates 1 to use according to the length of the opening 3. The outermost inverted U-shaped protective plates 1 at both ends are respectively clipped onto the retaining walls 2 on both sides of the opening 3, that is, the two outermost inverted U-shaped protective plates 1 have a part of overlap with the retaining walls 2. Then, the adjacent inverted U-shaped protective plates 1 are connected into one piece by bolts 6. Expansion screws are installed in the round holes 8 at the bottom of the inverted U-shaped protective plates 1 to fix the bottom of the inverted U-shaped protective plates 1 to the bottom of the retaining walls 2. In this way, several sections of inverted U-shaped protective plates 1 can seal the opening 3 without the need to set up formwork and pour concrete to seal the opening 3, avoiding construction safety hazards and greatly improving construction efficiency.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
