[0022] Please refer to Figures 1-6The utility model provides a technical scheme: a water -proof foundation pit support pile, including steel column 1, support plate 2 and anti -infiltration department 3, steel column 1 outer wall middle part welds support plate 2, and support plate 2 bottom end is connected with anti -infiltration department 3, and support plate 2 inside is provided with stake plate 4, stake plate 4 outside is provided with auxiliary mechanism 5, and auxiliary mechanism 5 includes limit plate 501, first limit piece 502, second limit piece 503, positioning rod 504, weight reduction cavity 505, limit hole 506, fixed rod 507, limit seat 508, clamping seat 509, support rod 510, bottom plate 511 with plug rod 512, steel column 1 is welded with limit plate 501 on the side close to support plate 2, and stake plate 4 outer wall one side is connected with first limit piece 502, and first limit piece 502 outer wall is connected with second limit piece 503, and second limit piece 503 outer wall is welded with support plate 2, and stake plate 4 top end both sides weld with positioning rod 504, and positioning rod 504 inside is provided with weight reduction cavity 505, stake plate 4 bottom end both sides are provided with the assembly hole corresponding with positioning rod 504, first limit piece 502 and second limit piece 503 are all " L " shape, stake plate 4 is provided with limit hole 506 on the side close to weight reduction cavity 505, and limit hole 506 inside is connected with fixed rod 507, fixed rod 507 outer wall one side welds with limit seat 508, and limit seat 508 inside is clamped and is connected with clamping seat 509, clamping seat 509 outer wall is connected with support rod 510 through rotating seat, and support rod 510 bottom end rotationally connected with bottom plate 511, bottom plate 511 inside slidingly connected with plug rod 512, limit seat 508 inside is provided with the storage cavity corresponding with clamping seat 509, and clamping seat 509 is " C " character shape, first limit piece 502 about stake plate 4 vertical midline is distributed, and weight reduction cavity 505 is distributed at stake plate 4, stake plate 4 outer wall middle part both sides are provided with the positioning slot corresponding with limit plate 501, support rod 510 and clamping seat 509 are rotationally connected, and first limit piece 502 and second limit piece 503 are clamped and connected.

[0023] In specific implementation, during use of the water-impermeable foundation pit support pile, the pile plate 4 is first placed in the support plate 2. Since the pile plate 4 is connected with the first limiting piece 502, and the limiting plate 501 is connected with the steel column 1, at this time, the pile plate 4 is along the limiting plate 501 on both sides, and the first limiting piece 502 is moved downward along the second limiting piece 503. At this time, the pile plate 4 is clamped and connected with the limiting plate 501, and the first limiting piece 502 is clamped and connected with the second limiting piece 503. Then, during the process of moving the pile plate 4 into the support plate 2, the pile plate 4 can be positioned without subsequent fixation of the pile plate 4 by bolts. Since the pile plate 4 has the positioning rods 504 connected on both sides of the top end and the assembly holes provided on both sides of the bottom end, the pile plates 4 can be spliced by sequentially butting the bottom of the pile plate 4 with the positioning rods 504. The weight of the pile plate 4 is reduced by providing the weight-reducing cavities 505 in the pile plate 4, thereby facilitating transportation of the pile plate 4 by means of split assembly and weight reduction.

[0024] In order to improve the stability of the pile plate 4 support, the limiting hole 506 is provided in the middle of the pile plate 4, and the limiting seat 508 is welded with the fixed rod 507. The limiting seat 508 is first moved to make the fixed rod 507 inserted into the limiting hole 506. At this time, the limiting seat 508 is attached to the pile plate 4, and the limiting seat 508 is arranged on the outer wall of the pile plate 4. Then, the clamping seat 509 is inserted into the limiting seat 508. At this time, the limiting seat 508 is clamped and connected with the clamping seat 509. Since the clamping seat 509 is rotationally connected with the support rod 510, the support rod 510 is rotated to make the top of the support rod 510 rotated along the clamping seat 509. Since the bottom of the support rod 510 is rotationally connected with the bottom plate 511, the movement of the support rod 510 drives the movement of the bottom plate 511. Until the bottom plate 511 is attached to the ground, the plug rod 512 is inserted into the ground through the bottom plate 511 to fix the bottom plate 511. At this time, the bottom plate 511, the support rod 510 and the pile plate 4 form a triangular stable structure, thereby improving the stability of the pile plate 4 support and ensuring that the ground of the foundation pit side wall does not slip, thereby playing a role of facilitating quick positioning assembly and stable support during use of the water-impermeable foundation pit support pile.

[0025] In summary, the water seepage prevention foundation pit support pile in use, first the steel column 1 is installed in the designated position in the foundation pit, then the pile plate 4 is inserted into the support plate 2, thereby preventing the collapse of the foundation pit wall and the sliding of the soil, at this time the pile plate 4 extrudes the anti-seepage part 3, and then through the anti-seepage part 3 so that it can be closely attached to the ground, improve the sealing property of the anti-seepage part 3, thereby preventing the peripheral water from seeping into the foundation pit from the contact position of the pile plate 4 and the ground, which is the prior art and will not be described in detail here, the first limiting piece 502 is moved along the second limiting piece 503 by the auxiliary mechanism 5, the pile plate 4 is moved into the support plate 2 along the limiting plate 501, and then the pile plate 4 is limited during the process of moving into the support plate 2, without the need for subsequent fixing of the pile plate 4 by bolts, and the pile plate 4 is transported by the split assembly and weight reduction, and the bottom plate 511, the support rod 510 and the pile plate 4 form a triangular stable structure, thereby assisting the support of the pile plate 4, improving the stability of the pile plate 4 support, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.
