[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Example 1 Figures 1-7 This utility model provides a technical solution:

[0027] A deep foundation pit support and reinforcement device includes a lower support 1, a side support 2 fixedly installed on the top of the lower support 1 near its left side, a side plate 3 fixedly connected to the side of the lower support 1, a downward positioning cylinder 4 fixedly connected to the top of the side plate 3, an adjustment cavity opened inside the lower support 1, an adjustment screw 5 rotatably connected to the inner wall of the adjustment cavity via a bearing, a threaded sleeve 6 threadedly connected to the surface of the adjustment screw 5, and the bottom of the threaded sleeve 6 slidingly abutting against the bottom of the adjustment cavity. The side is connected to a limiting component. The top of the threaded sleeve 6 is provided with a positioning screw groove 7. The inner wall of the positioning screw groove 7 is connected to a connecting reinforcement plate 8 by a screw. The top of the connecting reinforcement plate 8 is rotatably connected to a stabilizing frame 9 by a pin seat. One end of the stabilizing frame 9 is rotatably connected to a locking component by a pin seat. The surface of the locking component is connected to a support plate 10. The inside of the side support 2 is threadedly connected to a side threaded rod 11 by an internal thread groove. One end of the side threaded rod 11 is fixedly connected to a threaded cone 12.

[0028] Specifically, such as Figures 1-7As shown, the limiting assembly includes a limiting slide plate 16 and a limiting groove 17. The limiting slide plate 16 is fixedly connected to the side of the threaded sleeve plate 6. The limiting groove 17 is formed on the surface of the inner wall of the adjusting cavity. The inner wall of the limiting groove 17 and the surface of the limiting slide plate 16 are slidably connected. By setting the limiting slide plate 16 and the limiting groove 17, the movement trajectory of the threaded sleeve plate 6 is limited, so that the adjusting screw 5 rotates and drives the threaded sleeve plate 6 to move.

[0029] Furthermore, the locking assembly includes a locking magnetic plate 22 and a locking magnetic groove 23. The locking magnetic plate 22 is fixedly connected to one side of the support plate 10, and the locking magnetic groove 23 is opened on one end of the stabilizing frame 9. The inner wall of the locking magnetic groove 23 and the surface of the locking magnetic plate 22 are magnetically engaged and adapted. The magnetic connection effect between the locking magnetic plate 22 and the locking magnetic groove 23 can ensure that the installation of support plates 10 of different sizes on the stabilizing frame 9 is attached to the side wall of the deep foundation pit.

[0030] Specifically, such as Figures 1-7 As shown, the top of the lower support 1 is provided with an anti-slip side groove 18. The side of the connecting reinforcement plate 8 is fixedly connected with a bonding plate 19. The inner wall of the bonding plate 19 is threadedly connected with a lifting screw 20 through a threaded groove. The bottom of the lifting screw 20 is fixedly connected with an anti-slip clamping plate 21. The surface of the anti-slip clamping plate 21 abuts against the inner wall of the anti-slip side groove 18. There are at least four lifting screws 20, and the at least four lifting screws 20 are evenly distributed on both sides of the connecting reinforcement plate 8. After the support plate 10 abuts against the side wall in the deep foundation pit, the lifting screws 20 are rotated to move downwards, controlling the anti-slip clamping plate 21 to move into the inner wall of the anti-slip side groove 18, which plays a role in tightening and compressing the anti-slip effect. The at least four lifting screws 20 can be positioned at multiple points in the anti-slip side groove 18 to achieve the bottom and side control support and reinforcement effect in the deep foundation pit.

[0031] Please refer to Example 2 Figures 1-7 The difference between this embodiment and Embodiment 1 is that the main body of the lower positioning cylinder 4 is a fixed hollow cylinder, and a positioning lower cone 13 is placed on the inner wall of the fixed hollow cylinder, and the inner wall of the fixed hollow cylinder is coated with a wear-resistant and anti-slip coating. A sealing cover plate 14 is fixedly connected to the top of the positioning lower cone 13, and a locking plate 15 is fixedly connected to the bottom of the sealing cover plate 14. The bottom of the locking plate 15 and the top of the fixed hollow cylinder are engaged and adapted.

[0032] The working principle of this utility model is as follows: In use, a lower support 1 is provided for bottom support and positioning in a deep foundation pit. A side support 2 is provided at the top side of the lower support 1, allowing the threaded rod 11 to move and be positioned on the side wall of the deep foundation pit via the threaded movement within the side support 2. This allows the threaded cone 12 on the threaded rod 11 at the side of the side support 2 to be threaded into the side wall of the deep foundation pit. The lower cone 13, positioned at different depths within the lower positioning cylinder 4, is used for downward positioning of both sides of the lower support 1. Since the lower cone 13 is in an anti-slip state within the fixed hollow cylinder, it can be positioned by downward tapping with external force, thus achieving the effect of attaching and positioning the entire support and reinforcement device in the deep foundation pit. Depending on the inclination angle of the side wall of the deep foundation pit, subsequent secondary adjustments can be made to the position and angle of the stabilizing frame 9 and its upper support plate 10, allowing the operating adjustment screw 5 to rotate. By setting the limiting slide plate 16 and limiting slide groove 17, the movement trajectory of the threaded sleeve plate 6 is limited, so that the adjusting screw 5 rotates and drives the threaded sleeve plate 6 to move. The movement of the threaded sleeve plate 6 can drive the threaded connecting reinforcement plate 8 on it to move, thereby controlling the stabilizing frame 9 to move closer to or away from the side support 2. The support plate 10 can be replaced by the locking magnetic suction plate 22 and locking magnetic suction groove 23, so that support areas of different sizes can be connected to the stabilizing frame 9. After the support plate 10 abuts against the side wall in the deep foundation pit, the lifting screw 20 is rotated to move downward, controlling the anti-slip clamping plate 21 to move into the inner wall of the anti-slip side groove 18, so as to achieve the constraint and anti-slip effect of tightening and pressing. At least four lifting screws 20 can be positioned at multiple points in the anti-slip side groove 18 to achieve the bottom and side control support and reinforcement effect in the deep foundation pit.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
