Technical Field

[0001] This utility model relates to the field of basic engineering, specifically a retaining wall. Background Technology

[0002] With the continuous acceleration of urbanization, the demand for infrastructure construction is increasing day by day. As a commonly used engineering structure, retaining walls are widely used in railways, highways, water conservancy, construction and other fields. Especially in the process of foundation pit construction, retaining structures play a vital role in ensuring construction safety and preventing soil collapse.

[0003] During the construction of pipe laying in the foundation pit, retaining plates can provide structural support for the soil on the side of the foundation pit, effectively dispersing the soil pressure and ensuring the safe construction of pipe laying. Retaining plates are usually composed of retaining side plates and reinforcing crossbars. By moving the retaining plates, it is convenient to lay pipes in the foundation pit. The retaining plates are moved in the foundation pit by trailer. During the actual movement, uneven settlement is likely to occur at the bottom of the foundation pit, causing the retaining plates to get stuck in certain areas and become unusable, which greatly reduces the adaptability of the retaining plates. Utility Model Content

[0004] The purpose of this utility model is to provide a retaining plate to solve the problem mentioned in the background art that, during the actual movement of existing retaining plates, uneven settlement easily occurs at the bottom of the foundation pit, causing the retaining plate to become partially stuck and unable to continue to be used, which greatly reduces the adaptability of the retaining plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retaining plate includes a trolley, a traction rope at the rear of the trolley, a retaining side plate suspended at the end of the traction rope away from the trolley, the trolley drags the retaining side plate to slide via the traction rope, an installation block is inserted into the surface of the retaining side plate, a reinforcing crossbar is fixedly connected to the surface of the installation block, a threaded post is threadedly connected to the surface of the retaining side plate, a limit rod is fixedly connected to the surface of the threaded post, the limit rod is inserted into the surface of the retaining side plate, a lifting lug is fixedly connected to the top of the retaining side plate, a lifting mechanism is provided on the surface of the trolley, the lifting mechanism includes a slider, the slider is slidably connected to the surface of the retaining side plate, a hydraulic cylinder is fixedly connected to the surface of the retaining side plate, a support plate is fixedly connected to the piston rod of the hydraulic cylinder, a connecting nut is fixedly connected to the surface of the slider, a limit bolt is threadedly connected to the surface of the connecting nut, a limit groove is formed on the surface of the retaining side plate, and the limit bolt is inserted into the limit groove.

[0006] Preferably, the surface of the retaining side plate has multiple sets of rectangular grooves, which are arranged linearly and uniformly. The mounting block is inserted into the rectangular groove of the retaining side plate. The rectangular groove of the retaining side plate has a circular hole, and a threaded groove is formed directly below the circular hole.

[0007] Preferably, a circular hole is provided on the surface of the mounting block, and the limiting rod passes through both the circular hole of the retaining side plate and the circular hole of the mounting block, and the limiting rod drives the threaded column to reach the threaded groove of the retaining side plate.

[0008] Preferably, the limiting rod restricts the position of the mounting block on the rectangular groove of the retaining side plate. The retaining side plate is provided in two sets, and the two sets of retaining side plates support the reinforcing crossbar through the mounting block.

[0009] Preferably, the surface of the retaining side plate is provided with a guide groove, and the guide groove is trapezoidal in shape. The slider is trapezoidal in shape and slides on the guide groove of the retaining side plate. The slider drives the hydraulic cylinder and the support plate to slide horizontally on one side of the retaining side plate.

[0010] Preferably, the connecting nut and the limiting bolt move synchronously with the slider, and multiple sets of limiting circular grooves are provided and arranged linearly and evenly, with the limiting bolts inserted into the limiting circular grooves.

[0011] Preferably, the limiting bolt and the limiting groove restrict the sliding of the slider on the guide groove of the retaining side plate by connecting nuts, and the hydraulic cylinder drives the support plate to rise and fall by piston rod, and the support plate is in the shape of "L".

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the retaining plate encounters an area in the foundation pit where sliding is inconvenient and needs to be crossed, the hydraulic cylinder slides on one side of the retaining plate via a slider. When the hydraulic cylinder is moved to a position where it can be easily lifted, the limiting bolt on the surface of the connecting nut is rotated so that the limiting bolt is inserted into the limiting groove, thereby restricting the sliding of the hydraulic cylinder. At this time, the hydraulic cylinder drives the support plate to descend through the piston rod, causing the support plate to lift one end of the retaining plate. With the help of a trolley, the retaining plate is pulled by a traction rope to slide in the foundation pit, allowing the retaining plate to cross the uneven section of the foundation pit, thereby improving the adaptability of the retaining plate.

[0014] 2. This retaining plate involves inserting an installation block into the rectangular hole of the retaining side plate, and then inserting a limiting rod into the circular hole of the retaining side plate. The threaded post passes through the circular hole of the installation block, and the limiting rod moves the threaded post to the threaded hole of the retaining side plate. The threaded post is threaded into the threaded hole of the retaining side plate, thus restricting the position of the limiting rod on the retaining side plate. The limiting rod, through a hydraulic cylinder, restricts the position of the reinforcing crossbar on the retaining side plate, thereby completing the assembly of the retaining side plate and the reinforcing crossbar. The retaining plate is assembled from the retaining side plate and the reinforcing crossbar, facilitating transportation and allowing for flexible assembly according to the size of the foundation pit, thus improving the adaptability of the retaining plate.

[0021] Please see Figure 1-5 One embodiment provided by this utility model:

[0022] A retaining wall includes a trolley 1 with a traction rope 11 at its rear. The traction rope 11 is made of high-strength steel wire rope with an outer layer of wear-resistant rubber to ensure stable traction in complex terrain and reduce the impact of vibration on the structure. A retaining side plate 2 is suspended at the end of the traction rope 11 away from the trolley 1. The trolley 1 drags the retaining side plate 2 across the pit via the traction rope 11. An installation block 21 is inserted into the surface of the retaining side plate 2, and reinforcements are fixedly connected to the surface of the installation block 21. A threaded post 23 is threadedly connected to the surface of the crossbar 22 and the retaining side plate 2. A limit rod 24 is fixedly connected to the surface of the threaded post 23 and inserted into the surface of the retaining side plate 2. A lifting lug 25 is fixedly connected to the top of the retaining side plate 2. The lifting lug 25 is located on both sides of the top of the retaining side plate 2 and can be used to cooperate with cranes or other lifting equipment for aerial transport, thereby moving the retaining plate to the foundation pit. The retaining side plate 2 and the mounting block 21 are the main body of the retaining plate and are both made of steel. Assembled from multiple parts, this structure facilitates transportation and allows for flexible assembly based on the size of the excavation pit, enhancing the adaptability of the retaining plate. A lifting mechanism is installed on the surface of the trolley 1, comprising a slider 3 slidably connected to the surface of the retaining side plate 2. A hydraulic cylinder 31 is fixedly connected to the surface of the retaining side plate 2, and a support plate 32 is fixedly connected to the piston rod of the hydraulic cylinder 31. The hydraulic pump station driving the hydraulic cylinder 31 is placed on the ground near the excavation pit and connected to the hydraulic cylinder 31 via a high-pressure hose. A connecting nut 33 is fixedly connected to the surface of the slider 3, and a limit bolt 34 is threaded onto the surface of the connecting nut 33. A limit groove 35 is formed on the surface of the retaining side plate 2, and the limit bolt 34 is inserted into the limit groove 35. This lifting mechanism can lift one side of the retaining side plate 2, thereby raising the height of one side of the retaining plate. This allows the trolley 1 to drag the retaining side plate 2 across the uneven area of ​​the excavation pit via a traction rope 11, thus improving the adaptability of the retaining plate.

[0023] Furthermore, multiple sets of rectangular grooves are formed on the surface of the retaining side plate 2, and the rectangular grooves are arranged linearly and evenly. The mounting block 21 is inserted into the rectangular groove of the retaining side plate 2. The mounting block 21 restricts the installation position of the reinforcing crossbar 22 on the retaining side plate 2. There are four sets of reinforcing crossbars 22, which can be installed in different positions according to needs. The rectangular groove of the retaining side plate 2 is provided with a circular hole, and a threaded groove is provided directly below the circular hole to limit the mounting block 21 on the retaining side plate 2.

[0024] Furthermore, a circular hole is provided on the surface of the mounting block 21. The limiting rod 24 passes through both the circular hole of the retaining side plate 2 and the circular hole of the mounting block 21. The limiting rod 24 drives the threaded column 23 to the threaded groove of the retaining side plate 2. The threaded column 23 locks its position on the retaining side plate 2 by rotating on the threaded groove of the retaining side plate 2. The threaded column 23 restricts the position of the limiting rod 24 in the circular hole of the retaining side plate 2.

[0025] Furthermore, the limiting rod 24 restricts the position of the mounting block 21 on the rectangular groove of the retaining side plate 2. The retaining side plate 2 is provided in two sets. The two sets of retaining side plates 2 support the reinforcing crossbar 22 through the mounting block 21. The mounting block 21 also restricts the position of the reinforcing crossbar 22 on the trolley 1. The reinforcing crossbar 22 and the retaining side plate 2 form an "H" shape on the foundation pit, which ensures the structural stability of the retaining plate and can effectively bear the load of the side structure of the foundation pit.

[0026] Furthermore, a guide groove is provided on the surface of the retaining side plate 2, and the guide groove is trapezoidal in shape. The slider 3 is trapezoidal in shape and slides on the guide groove of the retaining side plate 2. The slider 3 drives the hydraulic cylinder 31 and the support plate 32 to slide horizontally on one side of the retaining side plate 2, thereby changing the position of the hydraulic cylinder 31 and the support plate 32 on the retaining side plate 2. This makes it easier to move the support plate 32 to a suitable position for descent. The support plate 32 descends to the bottom of the pit to support the retaining side plate 2, so that one end of the retaining side plate 2 is lifted up. During the movement, the retaining side plate 2 crosses the uneven slope section in the pit.

[0027] Furthermore, the connecting nut 33 and the limiting bolt 34 move synchronously with the slider 3. The limiting circular groove 35 is provided in multiple sets and is arranged linearly and evenly. The limiting bolt 34 is inserted into the limiting circular groove 35. The limiting bolt 34 changes its position on the connecting nut 33 by rotating on the connecting nut 33. After the limiting bolt 34 has rotated, it will also lock its position on the connecting nut 33, thereby maintaining relative stability.

[0028] Furthermore, the limiting bolt 34 and the limiting groove 35 restrict the sliding of the slider 3 on the guide groove of the retaining side plate 2 through the connecting nut 33, so as to avoid the sliding phenomenon of the support plate 32 supporting the retaining side plate 2. The hydraulic cylinder 31 drives the support plate 32 to rise and fall through the piston rod. The support plate 32 is in an "L" shape. The support plate 32 can slowly lift one end of the retaining side plate 2 processed on the foundation pit. The support plate 32 has a large contact area with the ground, which can effectively disperse the pressure, prevent the ground from collapsing or the support plate from sinking, and improve the lifting stability. In addition, an anti-slip rubber pad can be added to the bottom of the support plate 32 to enhance the friction and protect the ground.

[0029] Working principle: When encountering areas in the foundation pit that are inconvenient to slide over and need to be crossed, the hydraulic cylinder 31 slides on one side of the retaining side plate 2 via the slider 3. When the hydraulic cylinder 31 is moved to a position where it is convenient to lift, the limiting bolt 34 is rotated on the surface of the connecting nut 33, so that the limiting bolt 34 is rotated to be inserted into the limiting circular groove 35, thereby restricting the sliding of the hydraulic cylinder 31. At this time, the hydraulic cylinder 31 drives the support plate 32 to descend through the piston rod, so that the support plate 32 lifts one end of the retaining side plate 2. With the help of the trolley 1, the retaining side plate 2 is pulled by the traction rope 11 to slide in the foundation pit, so that the retaining plate can cross the uneven section in the foundation pit, thereby improving the adaptability of the retaining plate.

[0030] The mounting block 21 is inserted into the rectangular hole of the retaining side plate 2, and the limiting rod 24 is inserted into the circular hole of the retaining side plate 2, so that the threaded post 23 passes through the circular hole of the mounting block 21. The limiting rod 24 drives the threaded post 23 to move to the threaded hole of the retaining side plate 2. The threaded post 23 is threadedly connected to the threaded hole of the retaining side plate 2, thereby limiting the position of the limiting rod 24 on the retaining side plate 2. The limiting rod 24 limits the position of the reinforcing crossbar 22 on the retaining side plate 2 through the hydraulic cylinder 31, thereby completing the assembly of the retaining side plate 2 and the reinforcing crossbar 22. The retaining plate is assembled by splicing the retaining side plate 2 and the reinforcing crossbar 22, which can be easily transported and can be flexibly assembled according to the size of the foundation pit, thus improving the adaptability of the retaining plate.
