[0027] Each of the locking components 16 includes a plurality of telescopic slide rods 161 , and an anti-rotation block 162 is connected to the right side of each of the telescopic slide rods 161 , and a spring 163 is provided on the rod body of each telescopic slide rod 161 , and an anti-stuck arc section 164 is provided at the rear end of the right side surface of the anti-rotation block 162 .

[0028] A sleeve opening 211 is provided in the middle of the top surface of the auxiliary frame 21, a second opening 212 is provided through the lower end of the right side surface of the auxiliary frame 21, and a support slide rod sleeve seat 213 is provided laterally on the left side of the second opening 212, and an auxiliary lifting frame sleeve opening 214 is provided in the middle of the bottom surface of the auxiliary frame 21.

[0029] The reinforcement structure 3 includes a vertical splicing plate 31, and a pressure plate 32 that abuts against the side wall of the basement is horizontally arranged on the bottom surface of the vertical splicing plate 31, and a plurality of horizontal splicing beams 33 are horizontally connected to the left and right sides of the vertical splicing plate 31. A plurality of first strip screw holes 311 are opened on the upper and lower sides of the vertical splicing plate 31, and a plurality of second strip screw holes 331 are opened on the left and right ends of each of the horizontal splicing beams 33.

[0030] Working principle: First, a plurality of square openings matching the right end of the supporting structure 1 are evenly spaced on the wall surface of the basement side wall by a cutting machine; When opening the square sleeve, be careful not to open the square sleeve on the steel bars of the side wall, so as to ensure that the overall wall structure of the side wall is not affected after the square sleeve is opened.

[0031] Then, the auxiliary lifting frame 4, the auxiliary mechanism 2 and a supporting structure 1 are erected and assembled, and the supporting structure 1 is lifted and aligned with a square sleeve through the auxiliary lifting frame 4. In addition, each supporting slide bar 22 is pushed toward the basement side wall in turn, so that each suction cup 23 is adsorbed on the basement side wall through an external vacuum pump to support the displacement of the supporting structure 1 when it is working; When the support structure 1 is inserted into the square sleeve, it needs to be slowly displaced horizontally, and the auxiliary lifting frame 4 is generally not easy to be displaced horizontally against the wall, which has poor stability. Therefore, the auxiliary mechanism 2 is used to horizontally absorb the wall to perform horizontal displacement of the support structure 1 when it is installed, so as to enhance the stability of the support structure 1 when it is installed horizontally.

[0032] Then, when the support structure 1 is installed, the left side of the reinforcement seat assembly 11 is pushed horizontally toward the square sleeve, so that the drill 17 passes through the square sleeve to drill holes in the soil layer outside the basement side wall. When the two positioning components 16 are automatically retracted and sleeved on the front and rear walls of the square sleeve, the auxiliary lifting frame 4 and the auxiliary mechanism 2 are taken out downward, and the reinforcement seat assembly 11 is pushed horizontally again, so that the left side wall of the L-shaped slot 114 is against the basement side wall, and the support structure 1 is installed in the square sleeve. After the two locking components 16 on the supporting structure 1 are automatically retracted and locked into the square sleeve, the auxiliary frame 21 on the auxiliary mechanism 2 has been pushed to collide with each suction cup 23, and there is no way to push the auxiliary mechanism 2 anymore. Just remove the auxiliary lifting frame 4 and the auxiliary mechanism 2 first, and the subsequent support structure 1 is continued to be pushed into the square sleeve using the two locking components 16 for buffering and auxiliary support, which can ensure that when the drill 17 on the supporting structure 1 continues to drill into the bare soil layer, the reinforcement seat assembly 11 will not be driven to rotate in the square sleeve.

[0033] Then, the screw adjusting member 151 is twisted to make the push block 152 move rightward to push the push member 14, so that the push member 14 moves rightward and rises on the slide seat 13 to press against the top groove wall of the square sleeve, completing the unfolding and clamping of the support structure 1 in the square sleeve cavity, and then the anchor 12 starts to extend outward in multiple directions and insert into the soil layer to tighten and fix the support structure 1; When twisting the screw adjustment piece 151, an electric tool is used for operation, and the sloped slide groove 131 is designed to offset the transverse oblique section of the first oblique section 142, ensuring that the block body 141 can move right and rise, and the second sloped slide groove 144 is designed to offset the vertical oblique section of the second oblique section 153, ensuring that when the block body 141 moves right and rises, the push block 152 can slide obliquely downward in the second sloped slide groove 144 on the left side of the block body 141, so that the push block 152 will not be affected and stuck by the rightward movement and rise of the block body 141.

[0034] Finally, after all the supporting structures 1 are installed, a reinforcement structure 3 is connected between two vertically adjacent supporting structures 1 to provide pressure support for the basement side wall, and two laterally adjacent reinforcement structures 3 are connected in series through various transverse splicing beams 33, so that the supporting structures 1 are connected as a whole to provide uniform pressure support for the entire wall surface of the basement side wall.

[0035] By designing the reinforcement structure 3, the side wall surfaces between two adjacent supporting structures 1 can be supported against each other, and the tension on the side wall is on the anchors 12 of each supporting structure 1, so that most of the supporting structure 1 does not need to be left in the cavity of the basement, and when the basement roof is subsequently dismantled, the demolition materials will not collide with the supporting structure.
