[0028] 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.

[0029] Embodiment 1:

[0030] Please refer to Figures 1 to 4 , a kind of foundation pit support pile in this embodiment includes a plurality of support sheet piles 1, a connecting frame 2 and a support pile 3. The support sheet piles 1 are located on the inner wall of the foundation pit. The connecting frame 2 is fixedly connected to the surface of the support sheet pile 1, and the support pile 3 is arranged on the surface of the connecting frame 2.

[0031] Arrange a plurality of support sheet piles 1 neatly and insert them into the soil, and fix the connecting frame 2 to the support sheet piles 1, indirectly fixing a plurality of support sheet piles 1.

[0032] A connecting component 4 is provided on the surface of the connecting frame 2. The connecting component 4 is used to fix the support pile 3 to the connecting frame 2. The connecting component 4 includes a support plate 401, a plug rod 402, a limiting plate 403, a connecting seat 404, a support 405, a limiting piece 406 and a fixing rod 407. Among them, the support plate 401 is installed on the surface of the connecting frame 2. The support plate 401 is U-shaped and wraps around the surface of the connecting frame 2. The support plate 401 and the connecting frame 2 are fixed by bolts, and it is convenient to remove and install the support plate 401 through the bolts. The number of plug rods 402 is two, which are fixedly connected to the surface of the support plate 401. One end of the plug rod 402 away from the support plate 401 is conical, and the plug rod 402 is perpendicular to the support plate 401, which is convenient for inserting the plug rod 402 into the soil, so as to fix the support plate 401 to the ground. The limiting plate 403 is inserted into the inner side of the support plate 401 and is located inside the connecting frame 2. The height of the limiting plate 403 is greater than the height of the support plate 401, and the limiting plate 403 is perpendicular to the support plate 401. The limiting plate 403 can be used to limit the support pile 3, so that the support pile 3 supports the support plate pile 1. The connecting seat 404 is fixed to the support plate 401 and is rotatably connected to the support pile 3. The number of supports 405 is two, which are respectively installed at the top and bottom of the connecting seat 404. The number of limiting pieces 406 is two, and they are respectively located at the top and bottom of the support pile 3. The limiting piece 406 is slidably connected to the support 405. The fixing rod 407 is threadedly connected to the inside of the connecting seat 404 and penetrates and extends to the outside of the support plate 401.

[0033] Among them, the inside of the support 405 is hollow, and a sliding piece is connected to the surface of the limiting piece 406. The limiting piece 406 is located at the hollow part through the sliding piece and slides with the support 405. By sliding with the support 405 through the sliding piece, the limiting piece 406 can be more stable when sliding. The thickness of the connecting seat 404 is adapted to the inner spacing of the connecting frame 2, and a bolt hole is provided at the top of the connecting seat 404, so that the connecting seat 404 can be inserted into the inside of the connecting frame 2, and through the bolt hole, it is convenient for the connecting frame 2 to fix the connecting seat 404.

[0034] When the support pile 3 is parallel to the ground, the limiting piece 406 is slid so that the limiting piece 406 fits the surface of the support pile 3. Since the top and bottom of the support pile 3 are both limited by the limiting piece 406, the angle change of the support pile 3 can be prevented. The support plate piles 1 are arranged on both the left and right sides of the foundation pit, and the opposite ends of the two support piles 3 are fixed, so that the support pile 3 can support the support plate pile 1 and further strengthen it.

[0035] It should be noted that according to the actual width of the foundation pit, the length of the support pile 3 changes accordingly, and the purpose is to ensure that the opposite ends of the two support piles 3 can be fixed.

[0036] Embodiment Two:

[0037] Please refer to Figure 5 Based on the first embodiment, the support plate 401 is detached from the connecting frame 2, the support plate 401 is inserted into the ground and fixed to the ground, the support pile 3 rotates with the connecting seat 404, the bottom end of the support pile 3 is located inside the support plate 401, and the limiting plate 403 limits the support pile 3.

[0038] When the width of the foundation pit is too large or the depth of the foundation pit is relatively shallow, it is not convenient to adopt the suspended support reinforcement method. The support plate 401 can be detached from the connecting frame 2, the insertion rod 402 on the support plate 401 can be inserted into the soil for fixation, the limiting piece 406 can be slid until the limiting piece 406 is separated from the support pile 3, and the support pile 3 is rotatably connected to the connecting seat 404. Thus, the support pile 3 can be rotated to make the support pile 3 fit with the inner side of the support plate 401, and the limiting plate 403 is inserted into the support plate 401 to make the limiting plate 403 fit with the support pile 3, thereby limiting the support pile 3, further supporting the sheet pile 1, and improving the support effect.

[0039] The working principle is as follows:

[0040] First, a number of sheet piles 1 are neatly arranged and inserted into the soil, and the connecting frame 2 is fixed to the sheet piles 1, indirectly fixing multiple sheet piles 1. When choosing the suspended support method, the support pile 3 is parallel to the ground, and the limiting piece 406 is slid to make the limiting piece 406 fit with the surface of the support pile 3. Since the top and bottom of the support pile 3 are limited by the limiting piece 406, the support pile 3 can be prevented from changing its angle. Sheet piles 1 are arranged on both the left and right sides of the foundation pit, and the opposite ends of the two support piles 3 are fixed. Thus, the support pile 3 can support the sheet pile 1 and further reinforce it.

[0041] When the width of the foundation pit is too large or the depth of the foundation pit is relatively shallow, the support plate 401 can be detached from the connecting frame 2, the insertion rod 402 on the support plate 401 can be inserted into the soil for fixation, the limiting piece 406 can be slid, the support pile 3 can be rotated to make the support pile 3 fit with the inner side of the support plate 401, and the limiting plate 403 is inserted into the support plate 401 to make the limiting plate 403 fit with the support pile 3, thereby limiting the support pile 3, further supporting the sheet pile 1, and improving the support effect.
