At the same time, the fixing nail 2 can be inserted into the ground, thereby stabilizing the base plate 1.

[0032] A telescopic rod 1206 is symmetrically installed inside the connecting sleeve 1201, and a first spring 1205 is sleeved on the surface of the telescopic rod 1206. One side surface of the first spring 1205 is fixedly connected to the slider 1203, and the other side surface of the first spring 1205 is fixedly connected to the connecting sleeve 1201. The side surface of the telescopic rod 1206 away from the connecting sleeve 1201 is fixedly connected to the slider 1203, and a clamping block 1207 is fixedly connected in the middle of the other side surface of the slider 1203. The side surface of the clamping block 1207 away from the slider 1203 is symmetrically provided with a clamping groove 1208. Figure 6 , 7As shown, by pulling the pull rod 1202 with great force, the pull rod 1202 can drive the movement of the slider 1203, and the movement of the slider 1203 can drive the movement of the card block 1207, so that the card slot 1208 on the card block 1207 is squeezed with the card block 20, so that the third spring 19 is deformed, so that the card slot 1208 is separated from the card block 20, so that the card block 1207 is separated from the card slot 13, so that the direction of the support plate 9 can be adjusted. At the same time, after the support plate 9 is adjusted to a suitable position, by loosening the pull rod 1202, the slider 1203 is restored to its original position under the action of the first spring 1205, so that the card block 1207 and the card slot 13 are re-engaged together. At the same time, because the force of the first spring 1205 is greater than the force of the third spring 19, Thereby, the clamping block 1207 will squeeze the clamping block 20 under the action of the first spring 1205, so that the clamping block 20 squeezes the third spring 19, so that the clamping block 20 can be squeezed above the clamping block 1207. At the same time, after the clamping block 1207 moves to the initial position, the clamping block 20 is re-engaged with the clamping groove 1208 under the action of the third spring 19, thereby completing the limiting effect on the clamping block 1207, thereby completing the adjustment effect on the support plate 9, so that the side walls of deep foundation pits with different inclination angles can be supported, thereby improving the support efficiency of the side walls of deep foundation pits and reducing costs. At the same time, the first spring 1205 and the third spring 19 are rubber composite springs in the prior art, and the force of the first spring 1205 is greater than the force of the third spring 19.

[0033] The bottom surface of the support plate 9 is fixedly connected to a connecting shaft 10, and the connecting shaft 10 is rotatably connected to the bottom plate 1. Figure 1 As shown, the support plate 9 and the base plate 1 are connected via hinges.

[0034] A plurality of slots 13 are formed on one side of the support plate 9 near the bottom, and the slots 13 are engaged with the block 1207. Figure 7 As shown, the engagement between the card slot 13 and the card block 1207 can limit the support plate 9.

[0035] A limiting rod 14 is connected to one side surface of the threaded rod 4, and a second spring 15 is sleeved on the side surface of the limiting rod 14 away from the threaded rod 4. A fitting plate 16 is fixedly connected to one side surface of the second spring 15, and the other side surface of the second spring 15 is fixedly connected to the threaded rod 4. The side surface of the fitting plate 16 away from the second spring 15 is fitted and connected to the bottom plate 1. The limiting rod 14 is connected to the fitting plate 16 through, and a plurality of limiting grooves 17 are provided on the other side surface of the bottom plate 1, which are engaged with the limiting rod 14. Figure 5As shown, by pulling the limit rod 14, the limit rod 14 is separated from the limit groove 17, and then by rotating the threaded rod 4, the rotation of the threaded rod 4 can drive the movement of the threaded sleeve 5, and the connecting block 6 on the threaded sleeve 5 is connected with the base plate 1 through the connection, so that the connecting block 6 and the base plate 1 can limit the threaded sleeve 5, so that the threaded sleeve 5 can move horizontally on the threaded rod 4, and when the threaded sleeve 5 moves, it can drive the movement of the telescopic connecting rod 7, so that the telescopic connecting rod 7 can auxiliary support the support plate 9, so that the supporting force of the support plate 9 can be ensured, thereby preventing the support plate 9 from tilting. At the same time, the second spring 15 is also a rubber composite spring in the prior art. Through the action of the second spring 15, the engagement between the limit rod 14 and the limit groove 17 can be tighter.

[0036] A connecting groove 18 is symmetrically provided on both sides of the card slot 13. A third spring 19 is fixedly installed inside the connecting groove 18. A clamping block 20 is fixedly connected to the bottom surface of the third spring 19. The clamping block 20 is clamped and connected with the clamping groove 1208. Figure 7 As shown, through the action of the third spring 19, the engaging block 20 and the engaging groove 1208 are tightly engaged, and at the same time, by pulling the pull rod 1202 vigorously, the engaging groove 1208 can be separated from the engaging block 20, thereby separating the engaging block 1207 from the engaging groove 13.

[0037] Working principle: Before using this deep foundation pit support structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7As shown, first, when the angle of the support plate 9 needs to be adjusted, the pull rod 1202 can be pulled forcefully so that the pull rod 1202 can drive the movement of the slider 1203, and the movement of the slider 1203 can drive the movement of the clamping block 1207, so that the clamping groove 1208 on the clamping block 1207 is squeezed with the clamping block 20, so that the third spring 19 is deformed, so that the clamping groove 1208 is separated from the clamping block 20, so that the clamping block 1207 is separated from the clamping groove 13, so that the direction of the support plate 9 can be adjusted. At the same time, after the support plate 9 is adjusted to a suitable position, the pull rod 1202 is loosened so that the slider 1203 returns to its original position under the action of the first spring 1205, so that the clamping block 1207 and The slot 13 is re-engaged, and because the force of the first spring 1205 is greater than the force of the third spring 19, the block 1207 will squeeze the clamping block 20 under the action of the first spring 1205, so that the clamping block 20 squeezes the third spring 19, so that the clamping block 20 can be squeezed above the block 1207. At the same time, after the block 1207 moves to the initial position, the clamping block 20 is re-engaged with the clamping slot 1208 under the action of the third spring 19, thereby completing the limiting effect on the block 1207, thereby completing the adjustment effect on the support plate 9, so that the side walls of deep foundation pits with different inclination angles can be supported, thereby improving the support efficiency of the side walls of deep foundation pits and reducing costs.

[0038] Secondly, by pulling the limit rod 14 to separate the limit rod 14 from the limit groove 17, the threaded rod 4 is rotated so that the rotation of the threaded rod 4 can drive the movement of the threaded sleeve 5, and the connecting block 6 on the threaded sleeve 5 is connected with the base plate 1 through the connection, so that the connecting block 6 and the base plate 1 can limit the threaded sleeve 5, so that the threaded sleeve 5 can move horizontally on the threaded rod 4, and when the threaded sleeve 5 moves, it can drive the movement of the telescopic connecting rod 7, so that the telescopic connecting rod 7 can assist in supporting the support plate 9, thereby ensuring the supporting force of the support plate 9 and avoiding the support plate 9 from tilting.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
