In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1, please refer to the attached Figure 1 -Attached Figure 6 The utility model provides a technical solution: a cast-in-place pile for foundation pit, comprising a cast-in-place pile body 1, a reinforcement component 2 and a stabilization component 3 are respectively installed inside and on the top of the cast-in-place pile body 1, the reinforcement component 2 comprises a moving ring 21, a connecting column 22 and a reinforcement ring 23, the outer surface of the moving ring 21 is fixedly connected to the side of the connecting column 22, one end of the connecting column 22 away from the moving ring 21 is fixedly connected to the outer surface of the reinforcement ring 23, a plurality of groups of circular holes are provided on the outer surface of the reinforcement ring 23, and the connecting column 22 is located at the connection between the moving ring 21 and the reinforcement ring 23, and a limit block 211 is fixedly installed on the inner wall of the moving ring 21.

[0024] In this embodiment, by setting the limit plate 13, the positions of the movable ring 21 and the reinforcement ring 23 can be restricted to prevent the reinforcement ring 23 from being offset during the pouring process, thereby affecting the overall firmness. By cooperating with the A slide groove 111 and the limit block 211, the effect of the movable ring 21 and the reinforcement ring 23 moving downward is achieved.

[0025] The cast-in-place pile body 1 comprises a cast ring 11 , a limit column 12 and a limit plate 13 , and the movable ring 21 is clamped on the outer surface of the limit column 12 .

[0026] An A-sliding groove 111 adapted to the limiting block 211 is formed on the outer surface of the limiting column 12 , and the outer surface of the limiting block 211 is slidably connected to the inside of the A-sliding groove 111 .

[0027] The bottom of the limiting column 12 is fixedly connected to the inner bottom wall of the pouring ring 11, the limiting plate 13 is clamped in the inside of the A slide groove 111, and the bottom of the limiting plate 13 is in contact with the top of the movable ring 21. The top of the pouring ring 11 is provided with a B slide groove, and threaded holes are provided on both sides of the B slide groove.

[0028] Specifically, the limit block 211 is clamped inside the A slide groove 111, and then the movable ring 21 and the reinforcement ring 23 are driven to move downward, so that the movable ring 21 and the reinforcement ring 23 are located inside the limit column 12, and then the limit plate 13 is inserted into the A slide groove 111, so that the bottom end contacts the top of the movable ring 21. In this way, the spacing between each reinforcement ring 23 is equal and the reinforcement ring 23 itself is relatively stable, so that the reinforcement ring 23 is prevented from moving during the concrete pouring process, which leads to poor overall firmness.

[0029] Example 2, please refer to the attached Figure 1 -Attached Figure 6 The utility model provides a technical solution: a cast-in-place pile for foundation pit, comprising a cast-in-place pile body 1, a reinforcement component 2 and a stabilization component 3 are respectively installed inside and on the top of the cast-in-place pile body 1, the reinforcement component 2 comprises a moving ring 21, a connecting column 22 and a reinforcement ring 23, the outer surface of the moving ring 21 is fixedly connected to the side of the connecting column 22, one end of the connecting column 22 away from the moving ring 21 is fixedly connected to the outer surface of the reinforcement ring 23, a plurality of groups of circular holes are provided on the outer surface of the reinforcement ring 23, and the connecting column 22 is located at the connection between the moving ring 21 and the reinforcement ring 23, and a limit block 211 is fixedly installed on the inner wall of the moving ring 21.

[0030] In this embodiment, the position of the stabilizing plate 31 can be restricted by setting the fixed block 32 and the B slide groove, and the position of the stabilizing plate 31 can be fixed by setting the threaded bolt to prevent the stabilizing plate 31 from moving up and down during the pouring process.

[0031] The stabilizing assembly 3 includes a stabilizing plate 31 and a fixing block 32 . The outer surface of the stabilizing plate 31 is clamped to the inner wall of the pouring ring 11 .

[0032] The side of the fixing block 32 close to the limiting column 12 is fixedly connected to the outer surface of the stabilizing plate 31 . The fixing block 32 is located inside the B chute, and the bottom thereof contacts the top of the pouring ring 11 .

[0033] The fixing block 32 is fixed to the edge of the top of the pouring ring 11 by means of threaded bolts. A hole is formed on the outer surface of the stabilizing plate 31, and the diameter of the hole is equal to that of the circular hole.

[0034] Specifically, the fixing block 32 is inserted into the interior of the B slide groove so that the bottom of the fixing block 32 contacts the top of the grouting ring 11, and then the position of the stabilizing plate 31 and the grouting ring 11 are fixed by means of threaded bolts, and then suitable steel bars are passed through the holes and the round holes and contact the bottom of the grouting ring 11, so that the staff can better use the steel bars to reinforce the concrete, and the stabilizing plate 31 can be reused to reduce the cost of work.

[0035] Working principle:

[0036] Step 1: First, the staff member passes the limit block 211 through the inside of the A chute 111, so that the moving ring 21 and the reinforcement ring 23 can reach the bottom of the limit column 12 by their own gravity, and then passes the limit plate 13 through the inside of the A chute 111 and contacts the top of the limit block 211, and then returns to the operation, continuously adding the moving ring 21 and the reinforcement ring 23;

[0037] The second step, finally, pass the fixing block 32 through the interior of the B slide groove so that the bottom of the fixing block 32 contacts the top of the pouring ring 11, and use the threaded bolts to fix the stabilizing plate 31 to the inner wall of the pouring ring 11. Then pass the steel bars through the interior of the stabilizing plate 31 and the reinforcement ring 23, and pour the gap between the stabilizing plate 31 and the limit column 12. At this point, the entire workflow is completed.
