[0002] Due to various reasons such as survey, design, construction, changes in functional use and changes in the surrounding environment, the bearing capacity of the original foundation soil layer may be insufficient, which may cause the subsequently constructed buildings to easily sink. In order to ensure the stability of the building, it is necessary to reinforce it with pile foundations.

[0003] However, the existing pile foundations are mainly constructed by drilling and pouring concrete, and most of them are one-piece structures. In areas prone to earthquakes, the one-piece poured pile foundation structure has poor seismic resistance. It is fixed only by pouring the part under the ground, and has poor stability. After the existing pile foundations are poured, it is necessary to cast and splice the load-bearing columns on the top. However, the load-bearing columns are supported only by the pile bodies, resulting in the pressure on the load-bearing columns being borne by the piles, which can easily cause cracks in the piles and poor stability. Utility Model Content

There are two positioning splicing buckles 321 slidably inserted in one side of the first fixing sleeve 31, and a rotating sleeve 33 is fixedly installed in the middle of one side of the surface of the first fixing sleeve 31 and the second fixing sleeve 32, and a rotating member 34 is rotatably installed in the rotating sleeve 33, and a supporting leg 35 is fixedly installed on one side of the rotating member 34, and a supporting seat 36 is fixedly installed at the bottom end of the supporting leg 35, and a positioning bolt 361 is clamped in the inner thread of the supporting seat 36, and the positioning bolt 361 passes through the supporting seat 36 and is threadedly clamped in the positioning member 21;

[0020] By pouring the steel frame of the pile body 1, the pile body 1 located at the bottom of the fixing seat 2 is the underground part, and the top surface of the fixing seat 2 is used for pouring and connecting the load-bearing column. When the load-bearing column is poured on the pile body 1, the joint between the load-bearing column and the pile body 1 is reinforced by the reinforcement device 3, and the first fixing sleeve 31 and the second fixing sleeve 32 are sleeved on the surface of the joint. The first fixing sleeve 31 and the second fixing sleeve 32 are limited after the splicing by two splicing buckles 321. After the splicing is completed, The rotating sleeve 33 and the rotating part 34 cooperate to rotate the two supporting legs 35 so that the supporting seats 36 respectively installed at the bottom ends of the two supporting legs 35 are fitted with the top surfaces of the corresponding positioning parts 21. After the fitting is completed, the supporting seats 36 are fixed to the corresponding positioning parts 21 by the positioning bolts 361. After the fixing is completed, the reinforcement device 3 is installed. The joint between the load-bearing column cast on the top surface of the pile body 1 and the pile body 1 is reinforced by the reinforcement device 3, so as to reduce the bearing capacity of the pile body 1 and increase the stability of the pile body 1.

[0021] Auxiliary piles 22 are installed on the bottom surfaces of the four positioning members 21. The number of the auxiliary piles 22 is four. The four auxiliary piles 22 cooperate with the pile body 1 through the four positioning members 21 and the fixing seat 2. The fixing seat 2, the four positioning members 21 and the four auxiliary piles 22 are all formed by splicing steel bars and pouring concrete to form an integrated structure. With the cooperation of the four positioning members 21 on the four sides of the surface of the fixing seat 2 and the four auxiliary piles 22, the force-bearing area of ​​the pile body 1 is increased and its stability is increased.

[0022] A stabilizing frame 37 is fixedly installed on one side of the two supporting legs 35. There are two stabilizing frames 37. A stabilizing seat 371 is fixedly installed on the bottom end of the two stabilizing frames 37. The bottom surface of the stabilizing seat 371 is fitted with the top surface of the fixing seat 2. When the two supporting legs 35 are fixed, the stabilizing seats 371 installed on the bottom surfaces of the stabilizing frames 37 installed on one side of the two supporting legs 35 are fitted with the top surface of the fixing seat 2. The auxiliary supporting legs 35 complete the reinforcement of the joint between the foundation pile body 1 and the load-bearing column, thereby increasing the stability of the reinforcement device 3 after installation.

[0023] Positioning pins 311 are inserted on both sides of the top surface of the first fixing sleeve 31. There are two positioning pins 311. The two positioning pins 311 pass through the top surface of the first fixing sleeve 31 and are inserted in the splicing buckle 321. The two positioning pins 311 are used to complete the limited fixation of the two splicing buckles 321 after they are inserted into the first fixing sleeve 31, thereby completing the splicing of the first fixing sleeve 31 and the second fixing sleeve 32.

[0024] The pile body 1 is symmetrically installed with positioning rings 12 on the surface below the reinforcement device 3. There are two positioning rings 12, which cooperate with the first fixing sleeve 31 and the second fixing sleeve 32 respectively. The reinforcement device 3 is installed with the assistance of the two positioning rings 12. The bottom surfaces of the first fixing sleeve 31 and the second fixing sleeve 32 of the reinforcement device 3 are respectively placed on the corresponding upper surfaces of the positioning rings 12 to complete the splicing of the first fixing sleeve 31 and the second fixing sleeve 32.

[0025] One side of the first fixing sleeve 31 is symmetrically provided with positioning holes 312, and the splicing buckle 321 is slidably inserted into the positioning hole 312. The two splicing buckles 321 are respectively limited by the two positioning holes 312 to complete the pre-splicing of the first fixing sleeve 31 and the second fixing sleeve 32. The top surface of the pile body 1 is installed with reserved steel bars 11 distributed in a ring shape. The reserved steel bars 11 cooperate with the pile body 1, and the concrete load-bearing columns to be cast on the pile body 1 are spliced ​​and reinforced by the reserved steel bars 11 distributed in a ring shape.

[0026] Working principle: by pouring the steel frame of the pile body 1, the pile body 1 located at the bottom of the fixing seat 2 is the underground pouring part, and the top surface of the fixing seat 2 is divided into the load-bearing column pouring connection. After the load-bearing column is poured on the pile body 1, the joint between the load-bearing column and the pile body 1 is reinforced by the reinforcement device 3, and the first fixing sleeve 31 and the second fixing sleeve 32 are sleeved on the surface of the joint, and the first fixing sleeve 31 and the second fixing sleeve 32 are limited after the splicing is completed by two splicing buckles 321. After the splicing is completed, the two support legs 35 are rotated by the cooperation of the rotating sleeve 33 and the rotating member 34, so that the support seats 36 respectively installed at the bottom ends of the two support legs 35 are fitted with the top surface of the corresponding positioning member 21. After the fitting is completed, the support seat 36 is fixed on the corresponding positioning member 21 by the positioning bolt 361. After the fixing is completed, the reinforcement device 3 is installed;

[0027] The fixing seat 2, four positioning members 21 and four auxiliary piles 22 are all formed by splicing steel bars and pouring concrete, forming an integrated structure. With the cooperation of the four positioning members 21 on the four sides of the surface of the fixing seat 2 and the four auxiliary piles 22, the force-bearing area of ​​the pile body 1 is increased, thereby increasing its stability.
