For details, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above-mentioned design is used, although it fixes the support structure and strengthens the connection between the gripping plate and the ground, making the support structure more stable, since the splicing mechanism does not have an adjustment function, this device is difficult to splice two sets of support devices when supporting a non-horizontal foundation pit, thereby reducing the stability of the overall connection, and the circular plug rod is inserted into the soil by a threaded connection, so that the soil is easy to stick to the threaded rod, which is easy to increase friction, reduce the transmission efficiency of the threaded rod, reduce the use effect of the device, and is difficult to meet actual use needs." In terms of use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, an adjustment component 4 is added to the application document.

[0027] More specifically:

[0028] like Figure 1-Figure 4 As shown:

[0029] An adjustment assembly 4 is installed on the base plate 1 and the earth retaining plate 3. The adjustment assembly 4 includes a latch 401 arranged at the four corners of the base plate 1, a striking plate 402 fixed to the top of the latch 401, and a sliding pin 404 fixed to the upper surface of the striking plate 402. A movable through hole is opened on the side of the base plate 1 close to the latch 401. A striking hammer 403 is slidably connected to the surface of the sliding pin 404. A symmetrically arranged U-shaped rod 406 is fixed to the surface of the earth retaining plate 3. Two groups of U-shaped rods 406 are slidably connected to the surfaces of the two groups of U-shaped rods 406. Locking bolts 408 are threadedly connected to the two sides of the sliding block 407. The sliding block 407 and the support rod 2 are hinged by a hinge seat. Two groups of symmetrically arranged adjustment frames 409 are fixed on both sides of the earth retaining plate 3. The adjustment frames 409 are fixed with symmetrically arranged adjustment frames 409. The limiting rods 410 of the row, the surfaces of the two groups of limiting rods 410 are slidably connected with moving blocks 411, and the moving blocks 411 are slidably connected with a plug rod 1 412, and the surface of the plug rod 1 412 is wound with a spring 1 413, and the two ends of the spring 1 413 are respectively fixedly connected with the plug rod 1 412 and the moving block 411, and the surface of the adjustment frame 409 is provided with a plurality of groups of equidistantly arranged jacks 414 adapted to the plug rod 1 412, and the two sides of the retaining plate 3 are respectively provided with a clamping seat 2 421 and a clamping seat 1 417, and the inside of the clamping seat 2 421 is slidably connected with a plug rod 2 419, and the surface of the plug rod 2 419 is wound with a spring 2 420, and the two ends of the spring 2 420 are respectively fixedly connected with the plug rod 2 419 and the clamping seat 2 421, and the clamping seat 2 421 and the clamping seat 1 417 are designed in an upper and lower structure;

[0030] A circular hole one is provided on the surface of the sliding block 407 and is compatible with the U-shaped rod 406. The sliding block 407 and the U-shaped rod 406 are slidably connected through this circular hole one. A circular hole two is provided inside the moving block 411 and is compatible with the limiting rod 410. The moving block 411 and the limiting rod 410 are slidably connected through this circular hole two. A circular hole three is provided on the surface of the moving block 411 and is compatible with the insertion rod one 412. The insertion rod one 412 and the moving block 411 are slidably connected through this circular hole three.

[0031] In this embodiment: when using the asymmetric foundation pit support structure, the base plate 1 is first placed at the bottom of the asymmetric foundation pit, and the retaining plate 3 is fitted with the side wall of the asymmetric foundation pit. Then, the striking hammer 403 is slid to the top of the sliding pin 404 and slides downward to strike the striking plate 402, so that the striking plate 402 drives the pin 401 to move downward due to the impact force, so that the pin 401 is inserted into the soil. Through this operation, there is no need to insert the pin 401 into the soil by threading, so as to avoid being affected by soil, thereby further improving the convenience and practicality of the device fixation. Through this operation, the foundation pit is supported, and then multiple groups of support devices are spliced. When the side wall of the foundation pit is not in a horizontal state, the plug rod 412 is pulled to thereby press the spring 41 3 is stretched until the insertion rod 1 412 is moved out of the insertion hole 414, and the position lock of the moving block 411 is released. Then the moving block 411 is moved, and then it slides on the surface of the limit rod 410, and the movable block 411 drives the second clamping seat 421 and the first clamping seat 417 to move, until the clamping seat 1 417 and the second clamping seat 421 correspond to each other up and down, and the insertion rod 1 412 is released at the same time. At this time, the spring 1 413 rebounds and drives the insertion rod 1 412 to be inserted into the inside of the insertion hole 414, and then the position lock of the moving block 411 is completed, and the insertion rod 2 419 is pulled at the same time, and the spring 2 420 is stretched. When the clamping seat 1 417 and the clamping seat 2 421 correspond to each other, the insertion rod 2 419 is released, so that the insertion rod 2 419 is inserted into the inside of the clamping seat 1 417, thereby completing the connection locking.

[0032] When the distance between the first and second clamping seats 417 and 421 is large, the locking bolt 408 is rotated to release the position lock of the sliding block 407 and the U-shaped rod 406, thereby adjusting the height of the retaining plate 3 until the upper and lower surfaces of the first and second clamping seats 417 and 421 are in contact with each other. Through the above operation, when supporting a non-horizontal foundation pit, splicing operations can still be performed, thereby improving the stability of the overall connection, meeting actual use requirements, and improving the use effect of the device.

[0033] Going further;

[0034] In an optional embodiment, a rectangular groove is provided on the surface of the moving block 411, and an adjusting bolt 416 is provided in the rectangular groove. The surfaces at both ends of the adjusting bolt 416 are rotatably connected to the moving block 411 through bearings. The surface of the adjusting bolt 416 is threadedly connected to a slider 415. The first clamping seat 417 and the second clamping seat 421 are respectively fixedly connected to the corresponding slider 415.

[0035] The slider 415 is adapted to fit into the rectangular slot.

[0036] In this embodiment: when there is a slight deviation between the second holder 421 and the first holder 417, the adjusting bolt 416 is rotated to drive the slider 415 to move, and the slider 415 drives the first holder 417 or the second holder 421 to move and fine-tune, thereby further improving the flexibility and practicality of the device. Since the slider 415 is adapted to the rectangular groove, it can have a limiting effect on the movement of the first holder 417 and the second holder 421, making the first holder 417 and the second holder 421 more stable during movement.

[0037] Going further;

[0038] In an optional embodiment, a protective plate 418 is fixed to the surface of the moving block 411, and moving grooves matching the protective plate 418 are opened on the surfaces of the holder 1 417 and the holder 2 421, and the holder 1 417 and the holder 2 421 are slidably connected to the protective plate 418 through the moving grooves.

[0039] In this embodiment: while the holder 1 417 and the holder 2 421 are moving, the protective plate 418 can shield the dislocated rectangular groove to prevent the surface of the adjusting bolt 416 from being stained with mud, thereby affecting the meshing effect of the adjusting bolt 416 and the slider 415, and further improving the effect of the device.

[0040] Going further;

[0041] In an optional embodiment, a symmetrically arranged installation groove is opened on one side of the upper surface of the base plate 1 close to the latch 401, and a telescopic rod 405 is arranged in the installation groove, and both ends of the telescopic rod 405 are fixedly connected to the striking plate 402 and the base plate 1 respectively.

[0042] In this embodiment, the striking plate 402 and the bottom plate 1 are connected by a telescopic rod 405, which can limit and fix the latch 401, making the latch 401 more stable during movement.

[0043] The working principle and use process of the utility model: when using this asymmetric foundation pit support structure, first place the base plate 1 at the bottom of the asymmetric foundation pit, and at the same time fit the retaining plate 3 with the side wall of the asymmetric foundation pit, then slide the striking hammer 403 to the bottom of the sliding pin 404, and slide downward to strike the striking plate 402, so that the striking plate 402 drives the pin 401 to move downward due to the impact force, so that the pin 401 is inserted into the soil. Through this operation, there is no need to insert the pin 401 into the soil by threading, so as to avoid being affected by soil, and further improve the convenience and practicality of the device fixation.

[0044] At the same time, the striking plate 402 and the bottom plate 1 are connected by the telescopic rod 405, which can limit and fix the latch 401, making the latch 401 more stable during movement. Through this operation, the foundation pit is supported.

[0045] Then, multiple sets of support devices are spliced ​​together. When the side wall of the foundation pit is not in a horizontal state, the spring 413 is stretched by pulling the plug rod 412 until the plug rod 412 is moved out of the insertion hole 414, thereby releasing the position lock of the moving block 411.

[0046] Then, the moving block 411 is moved, and then slides on the surface of the limit rod 410, and the moving block 411 drives the second card seat 421 and the first card seat 417 to move, until the first card seat 417 and the second card seat 421 correspond to each other up and down, and the insertion rod 1 412 is released at the same time. At this time, the spring 1 413 rebounds and drives the insertion rod 1 412 to be inserted into the inside of the socket 414, and then the position of the moving block 411 is locked, and the insertion rod 2 419 is pulled, and the spring 2 420 is stretched. When the card seat 1 417 and the card seat 2 421 correspond to each other, the insertion rod 1 is released. The second 419 allows the second rod 419 to be inserted into the inside of the bracket 1 417, thereby completing the connection locking. When the distance between the bracket 1 417 and the bracket 2 421 is large, the position locking of the sliding block 407 and the U-shaped rod 406 is released by rotating the locking bolt 408, thereby adjusting the height of the retaining plate 3 until the upper and lower surfaces of the bracket 1 417 and the bracket 2 421 are in contact with each other. Through the above operation, when supporting the non-horizontal foundation pit, the splicing operation can still be performed, thereby improving the stability of the overall connection, meeting the actual use needs, and improving the use effect of the device.

[0047] When there is a slight deviation between the second holder 421 and the first holder 417, the adjusting bolt 416 is rotated to drive the slider 415 to move, and the slider 415 drives the first holder 417 or the second holder 421 to move and adjust slightly, thereby further improving the flexibility and practicality of the device. Since the slider 415 is adapted to the rectangular groove, it can limit the movement of the first holder 417 and the second holder 421, making the movement of the first holder 417 and the second holder 421 more stable. While the first holder 417 and the second holder 421 are moving, the protective plate 418 can shield the misaligned rectangular groove to prevent the surface of the adjusting bolt 416 from being stained with mud, which would affect the meshing effect of the adjusting bolt 416 and the slider 415, thereby further improving the effectiveness of the device.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
