There are multiple connecting steel plates 4, and multiple connecting steel plates 4 can be spliced ​​together. A retaining plate 5 is detachably connected to the side of the connecting steel plate 4 away from the installation plate 3.

[0020] It should be noted that when using this utility model, firstly, insert the rod 20 at the bottom of the fixing base 1 into the ground to fix the position of the fixing base 1. Then, connect the mounting plate 3 at the end of the support rod 15 to the connecting steel plate 4. Select the required number of connecting steel plates 4 according to the support surface and splice the connecting steel plates 4 together. When splicing, engage and fix the connecting rod 6 on one connecting steel plate 4 with the connecting groove 7 on the adjacent connecting steel plate 4. Insert the rod 20 at the bottom of the connecting steel plate 4 into the ground and connect the mounting plate 3 to the connecting steel plate 4. The slider on the mounting plate 3 will slide and move to the slider on the connecting steel plate 4. Inside the groove 9, the distance between the two support rods 15 is adjusted as needed so that the support rods 15 can be symmetrically supported on the surface of the connecting steel plate 4. Rotating the rotating disk 19 causes the worm 17 to rotate, and the bidirectional lead screw 11 rotates through the meshing connection between the worm 17 and the worm wheel 18. The distance between the two sliding blocks 13 is adjusted through the threaded connection between the two sliding blocks 12 and the two ends of the bidirectional lead screw 11, thereby adjusting the distance between the two sliding plates 13 and the distance between the two support rods 15, so as to achieve uniform support force on the connecting steel plate 4. After adjusting the position of the sliding plates 13, they are fixed by tightening bolts, and the retaining plate 5 is spliced ​​with the connecting steel plate 4 to block the soil in the foundation pit.

[0021] The support assembly 2 includes a slide plate 13 and a support rod 15. The slide plate 13 is symmetrically slidably disposed on the top of the fixed base 1. A two-way screw 11 is rotatably connected inside the fixed base 1, and sliding blocks 12 are symmetrically threaded to both ends of the two-way screw 11. The top ends of the two sliding blocks 12 pass through the fixed base 1. The ends of the two slide plates 13 are respectively fixedly connected to the two sliding blocks 12. A U-shaped groove is opened on the top of the end of the slide plate 13 away from the sliding block 12, and the support rod 15 is rotatably connected inside the U-shaped groove. The mounting plate 3 is integrally disposed on one end of the support rod 15, and the end of the support rod 15 away from the slide plate 13 is rotatably connected inside the U-shaped groove.

[0022] It should be noted that when the bidirectional lead screw 11 is driven to rotate, the distance between the two sliding blocks 12 and the two ends of the bidirectional lead screw 11 is adjusted by the threaded connection between the two sliding blocks 12 and the two sliding plates 13, thereby adjusting the distance between the two support rods 15, so that the two support rods 15 can be symmetrically supported on the surface of the connecting steel plate 4, so that the connecting steel plate 4 is subjected to uniform support force, thereby better blocking the soil.

[0023] The end of the bidirectional lead screw 11 is fixedly connected to a worm gear 18 through a fixed base 1. A fixed plate 16 is symmetrically arranged at the end of the fixed base 1 outside the worm gear 18, and a worm 17 is rotatably connected between the two fixed plates 16. The worm 17 is meshed with the worm gear 18. A rotating disk 19 is rotatably arranged on the side wall of the fixed plate 16. The end of the worm 17 passes through the fixed plate 16 and is fixedly connected to the central axis of the rotating disk 19.

[0024] It should be noted that the worm 17 is rotated by rotating the rotating disk 19, and the bidirectional lead screw 11 is rotated by the meshing connection between the worm 17 and the worm wheel 18. The rotating disk 19 here can be set as a servo motor, and the rotation of the bidirectional lead screw 11 can be driven by the servo motor, which can also save manpower.

The ends of the fastening bolts on the surface of the mounting plate 3 are threaded into the fixing holes 10.

[0026] It should be noted that the mounting plate 3 at the end of the support rod 15 is detachably connected to the connecting steel plate 4. When the mounting plate 3 is connected to the connecting steel plate 4, the slider on the mounting plate 3 moves into the groove 9 on the connecting steel plate 4. The distance between the two support rods 15 can be adjusted as needed so that the support rods 15 can be symmetrically supported on the surface of the connecting steel plate 4. After adjusting the position of the slide plate 13, it is fixed by tightening the bolts.

[0027] A connecting slot 7 is provided on one side wall of the connecting steel plate 4, and a connecting rod 6 is integrally provided on the other side wall of the connecting steel plate 4. The connecting rod 6 is engaged in the connecting slot 7. A fixing slot is provided on one side of the connecting steel plate 4, and a fixing rod 8 is integrally provided on the side of the connecting steel plate 4 away from the mounting plate 3. The fixing rod 8 is engaged in the fixing slot.

[0028] It should be noted that the connecting steel plates 4 are splicable. The number of connecting steel plates 4 required is selected according to the support surface, and the connecting steel plates 4 are spliced ​​together. When splicing, the connecting rod 6 on one connecting steel plate 4 is engaged and fixed with the connecting groove 7 on the adjacent connecting steel plate 4, and the insert rod 20 at the bottom of the connecting steel plate 4 is inserted into the ground.

[0029] Insert rods 20 are provided at equal intervals at the bottom of both the fixed base 1 and the connecting steel plate 4.

[0030] It should be noted that the insertion rod 20 enhances the support stability of the fixing base 1 and the connecting steel plate 4.

[0031] The top of the fixed seat 1 is symmetrically provided with a limiting groove 14 outside the double-acting screw 11, and the bottom of the slide plate 13 is symmetrically provided with a limiting block, which is slidably connected inside the limiting groove 14.

[0032] It should be noted that the slide plate 13 slides on the fixed base 1, with one end fixed to the sliding block 12. During the sliding process, the limiting block 13, which is symmetrically arranged at one end of the sliding block 12, slides inside the limiting groove 14, so that the slide plate 13 can slide smoothly on the fixed base 1.
