[0002] A foundation pit is an earth pit excavated at the design position of the foundation according to the base elevation and the foundation plane size. In order to prevent the outer soil layer from collapsing into the pit, it is necessary to use support plates on the inner wall of the foundation pit to support the soil side wall, and at the same time use a support structure to support and fix the support plates. After retrieval, it is found that the patent application number "202320930302.3" discloses "an in-pit support structure for a foundation pit", which records that "including a bottom plate, a lifting component is fixedly connected to the top end of the bottom plate, an adjusting component is installed at the top end of the adjusting component, and a support plate is installed on the side of the lifting component". The above support structure makes the use height of the adjusting component easy to adjust through the set lifting component, so that the support structure can adapt to the support of foundation pits with different depths. At the same time, the lifting component and the adjusting component are detachable, and the adjusting component and the support plate are detachable, so that the support component is convenient to carry. However, there are still some deficiencies in the above structure when in use: Although the above structure can be disassembled and is convenient to carry, when in use, since only the use height of the support plate can be adjusted, for relatively deep foundation pits, it is difficult for the above structure to effectively support the side wall of the foundation pit, and there is still a risk of collapse. Based on this, we propose a support device that is convenient to carry and can effectively support the side wall of the foundation pit. Content of the Utility Model

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A foundation pit support device for preventing foundation pit collapse, including a support plate 1 and a fixing device for fastening the support plate 1. The fixing device includes a fixing pile 2. An installation cavity 3 is opened in the fixing pile 2. Strip-shaped grooves 4 penetrating the installation cavity 3 are opened on both sides of the fixing pile 2. A driving assembly 5 is installed in the installation cavity 3. A chute 6 is opened on the side surface of the support plate 1.

[0020] In this embodiment, the driving assembly 5 includes a lead screw 51 rotatably installed in the installation cavity 3. A driving block 52 is installed on the surface of the lead screw 51. Connecting rods 53 are fixedly connected to both sides of the driving block 52. The connecting rods 53 pass through the strip-shaped grooves 4 and extend to the outside and are fixedly connected to the first connecting block 54. The first connecting block 54 is rotatably connected to one end of a support rod 55. The other end of the support rod 55 is rotatably connected to the second connecting block 56. The second connecting block 56 is fixedly connected to the slider 57. The slider 57 is slidably connected to the chute 6. A square insertion rod 7 is fixedly connected to the bottom end of the fixing pile 2. One end of the lead screw 51 extends to the top of the fixing pile 2 and is fixedly connected to the bottom end of the connecting column 8. A storage groove 9 matching the size of the square insertion rod 7 is opened at the top end of the connecting column 8.

[0021] Specifically, by slidably installing the slider 57 in the chute 6, then inserting the fixing pile 2 into the bottom of the foundation pit through the square insertion rod 7, and then rotating the connecting column 8, the connecting column 8 will drive the screw rod 51 to rotate. Therefore, the driving block 52 will move up and down along the direction of the screw rod 51, and the driving block 52 will drive the connecting rod 53 to move up and down. Under the action of the support rod 55, the first connecting block 54 and the second connecting block 56, the slider 57 presses against the support plate 1, so as to tightly press the support plate 1 against the side wall of the foundation pit, thereby supporting the side wall of the foundation pit in this way to avoid the collapse of the foundation pit. By assembling multiple fixing devices by inserting the square insertion rod 7 into the receiving groove 9, the support device can effectively support the side walls of foundation pits with different depths.

[0022] In this embodiment, the size of the driving block 52 matches the size of the installation cavity 3, and the width of the connecting rod 53 is the same as the width of the strip groove 4.

[0023] Specifically, in this way, when the screw rod 51 rotates, the driving block 52 can drive the connecting rod 53 to move up and down along the directions of the screw rod 51 and the strip groove 4.

[0024] In this embodiment, the size of the chute 6 matches the size of the slider 57, and both the chute 6 and the slider 57 are cross-shaped.

[0025] Specifically, in this way, when the slider 57 is slidably installed in the chute 6, the slider 57 will not easily fall off from the chute 6.

[0026] In this embodiment, a tip 10 is provided at the bottom end of the square insertion rod 7.

[0027] Specifically, the provided tip 10 facilitates the insertion of the square insertion rod 7 into the bottom of the foundation pit.

[0028] In this embodiment, a reinforcing rib 11 is installed on the side surface of the support plate 1.

[0029] Specifically, the provided reinforcing rib 11 can conveniently improve the service strength of the support plate 1.

[0030] In this embodiment, the sum of the heights of the fixing pile 2 and the connecting column 8 is the same as the height of the support plate 1.

[0031] Specifically, in this way, it is convenient to stack and assemble the device for use.

[0032] Working principle: First, place the support plate 1 on the side wall of the foundation pit, then place the fixing device between the two support plates 1. After installing the slider 57 in the chute 6, insert the fixing pile 2 downward into the bottom of the foundation pit. Thus, the fixing pile 2 can be fixed to the bottom of the foundation pit through the square insertion rod 7. Then, rotate the connecting column 8 so that the driving block 52 drives the connecting rod 53 to move up and down along the direction of the strip groove 4. Furthermore, drive the slider 57 through the support rod 55 to tightly press the support plate 1 against the side wall of the foundation pit, thereby completing the support of the foundation pit. After that, insert the square insertion rod 7 in the top fixing device into the receiving groove 9 of the connecting column 8 at the top of the bottom fixing device, so that multiple such devices can be stacked and assembled to effectively support foundation pits of different depths, improving the support effect of the foundation pit. The fixing device is detachable from the support plate 1, making the device more convenient to carry.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
