[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figures 1-4 As shown, this utility model provides a retaining wall assembly for a civil building foundation pit, comprising: two baffles 1 and a support plate 102, both sides of the support plate 102 are provided with threaded grooves 114, and adjusting screws 104 are threadedly installed inside the two threaded grooves 114; it also includes: two connecting blocks 109, both fixedly installed at opposite ends of the two adjusting screws 104; two T-shaped grooves 105, both opened at the upper ends of the opposite faces of the two baffles 1, and T-shaped plates 106 are movably embedded inside the two T-shaped grooves 105, and fixing blocks 115 are fixedly installed at the lower ends of the opposite faces of the two T-shaped plates 106; two round shafts 116, both fixedly installed on the opposite faces of the two fixing blocks 115, and U-shaped plates 117 are movably sleeved on the outer surfaces of the two round shafts 116, and rotating shafts 118 are fixedly embedded inside the two U-shaped plates 117, and two connecting blocks 109 are movably sleeved on the outer surfaces of the rotating shafts 118; and a handle 103, fixedly installed at the top center of the support plate 102.

[0032] In this embodiment, two baffles 1 are placed inside the pit. Then, two adjusting screws 104 are rotated, allowing the two adjusting screws 104 to move relative to or away from each other. This can adjust the baffles 1 according to the width of the pit, making the baffles 1 fit better against the inner wall of the pit. When the adjusting screws 104 rotate, one end is connected to the rotating shaft 118 via a connecting block 109. The rotating shaft 118 is fixedly embedded inside the U-shaped plate 117, while the U-shaped plate 117 is movably sleeved on the outer surface of the round shaft 116. Therefore, when the adjusting screws 104 rotate to adjust the length, they will not move the baffles. Rotating the baffle 1 only allows it to move left and right, making it fit better against the inner wall of the pit. When the pit is wider at the top and narrower at the bottom, the lower end of the baffle 1 is first fixed through the mounting hole 113 on the outer surface of the L-shaped plate 112. The L-shaped plate 112 is movably sleeved on the outer surface of the connecting shaft 111, so the baffle 1 can be adjusted according to the angle of the pit. Then, the adjusting screw 104 is rotated for adjustment. The connecting block 109 is movably sleeved on the outer surface of the rotating shaft 118, so the angle of the baffle 1 can be adjusted to make it fit better against the pit.

[0033] Example 2, as Figures 1-4As shown, each of the two T-shaped grooves 105 has a limiting hole 119 at its upper end, and each of the two T-shaped plates 106 has a limiting pin 107 movably embedded at its upper end on the opposite side. Each of the two limiting pins 107 has a spring 108 fixedly connected to its outer surface, and the other end of each spring 108 is fixedly connected to the outer surface of the T-shaped plate 106. Each of the two baffles 1 has a plurality of positioning cones 101 fixedly installed on its opposite back side. Each of the two baffles 1 has a plurality of mounting blocks 110 fixedly installed at its lower end on the opposite side, and the plurality of mounting blocks 110 are divided into two groups. Each of the two groups of mounting blocks 110 has a connecting shaft 111 fixedly embedded on its opposite side, and each of the two connecting shafts 111 has an L-shaped plate 112 movably fitted on its outer surface. Each of the two L-shaped plates 112 has a plurality of mounting holes 113 on its outer surface.

[0034] In this embodiment, multiple positioning cones 101 are fixedly installed on both sides of the baffle 1. The positioning cones 101 can improve the stability of the baffle 1 and make it better installed inside the foundation pit. When disassembly is required, the limiting pin 107 is pulled out from the inside of the limiting hole 119, and then the T-shaped plate 106 is taken out from the inside of the T-shaped groove 105. The retaining component can be disassembled and it is easier to move it. The support plate 102 can be easily picked up by the handle 103. The two springs 108 can prevent the limiting pin 107 from being lost. Under the action of its elasticity, the limiting pin 107 can also drive the limiting pin 107 to be inserted into the inside of the limiting hole 119 to limit and fix the T-shaped plate 106, so that it is more stably embedded in the inside of the T-shaped groove 105.

[0035] Working principle: In use, place the two baffles 1 inside the pit, and then rotate the two adjusting screws 104. The two adjusting screws 104 move relative to each other or away from each other, which can drive the baffles 1 to adjust according to the width of the pit, so that the baffles 1 fit better against the inner wall of the pit. When the adjusting screws 104 rotate, one end is connected to the rotating shaft 118 through the connecting block 109. The rotating shaft 118 is fixedly embedded inside the U-shaped plate 117, and the U-shaped plate 117 is movably sleeved on the outer surface of the round shaft 116. Therefore, when the adjusting screws 104 rotate to adjust the length, they will not drive the baffles 1 to rotate, but only drive the baffles 1 to move left and right, so that the baffles 1 fit better against the inner wall of the pit. When the pit is wider at the top and narrower at the bottom, first fix the lower end of the baffle 1 through the mounting hole 113 opened on the outer surface of the L-shaped plate 112. The L-shaped plate 112 is movably sleeved on the outer surface of the connecting shaft 111, so it can be adjusted according to the angle of the pit. Adjust the baffle 1, and then adjust it by rotating the adjusting screw 104. The connecting block 109 is movably sleeved on the outer surface of the rotating shaft 118, so the angle of the baffle 1 can be adjusted to make the baffle 1 fit better with the foundation pit. Multiple positioning cones 101 are fixedly installed on both sides of the baffle 1. The positioning cones 101 can improve the stability of the baffle 1 and make it better installed inside the foundation pit. When disassembly is required, pull the limiting pin 107 out from the inside of the limiting hole 119, and then take out the T-shaped plate 106 from the inside of the T-shaped groove 105. The retaining component can then be disassembled, making it easier to move. The support plate 102 can be easily picked up by the handle 103. The two springs 108 can prevent the limiting pin 107 from being lost, and can also drive the limiting pin 107 to be inserted into the inside of the limiting hole 119 under its elastic force to limit and fix the T-shaped plate 106, making it more stably embedded inside the T-shaped groove 105.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
