[0002] Concrete cast-in-place piles are a common construction method for foundation engineering, usually used in the foundation construction of large buildings or bridges. It is formed by drilling holes in the foundation, using a steel cage as a skeleton, and pouring concrete into the holes. Concrete cast-in-place piles have the advantages of strong bearing capacity, convenient construction, and a wide range of applications, and are widely used in construction projects.
[0003] A cast-in-place pile mentioned in an existing Chinese public patent (authorization announcement number: CN218346158U) can be constructed by arranging multiple reinforcing steel bars, protective ring plates, anti-collision rings and connecting pieces. Multiple reinforcing steel bars pass through the protective ring plates, and the anti-collision rings are placed on the reinforcing steel bars. The anti-collision rings are stably connected to the protective ring plates through the connecting pieces, and then pouring is carried out. It is only necessary to pour the concrete until the protective ring plates are flush with the protective ring plates. After the concrete is formed, the connecting pieces are opened and the anti-collision rings are removed, thereby reducing the possibility of the operator breaking the concrete on the pile head and improving the construction efficiency.

[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The embodiment of the present application discloses a concrete cast-in-place pile reinforcement device.
[0034] Reference Figure 1 and Figure 2 A concrete cast-in-place pile reinforcement device includes a base plate 1, a through hole is opened inside the base plate 1, a pile body 2 is arranged inside the through hole, the pile body 2 is slidably arranged with the through hole, a steel cage 3 is arranged inside the pile body 2, the steel cage 3 is slidably arranged with the pile body 2, a plurality of reinforcement mechanisms are equidistantly arranged on the top of the base plate 1, and a plurality of clamping mechanisms are equidistantly arranged on the top of the base plate 1.
[0035] When performing bored pile construction, first drill a hole at a suitable position of the foundation, then use a crane to place the pile body 2 in the drilled hole, before placing the steel cage 3, it is necessary to clean the pile bottom, and then use a crane to place the steel cage 3 into the pile body 2. The setting of the steel cage 3 can increase the bearing capacity and tensile resistance of the pile body 2, and then pour cement mortar into the pile body 2 to ensure that the filling is uniform and dense to increase the stability and bearing capacity of the pile body 2, and then use an instrument to detect the verticality of the steel cage 3 to ensure that the position and direction of the steel cage 3 meet the design requirements, and finally wait for the cement mortar in the bored pile to solidify and reach the strength requirement before completing the bored pile construction. The pile body 2 can be clamped by a clamping mechanism to improve the stability of the pile body 2 during work, and the substrate 1 can be made more connected to the foundation by a reinforcement mechanism.
[0036] Reference Figure 2 and Figure 3 The clamping mechanism includes a plurality of threaded blocks 14 fixedly connected to the top of the base plate 1, the internal threads of the threaded blocks 14 are connected to a threaded rod 15, one end of the threaded rod 15 is fixedly connected to a hand wheel 16, the other end of the threaded rod 15 is rotatably connected to a clamping block 17, and the bottom of the clamping block 17 is slidably connected to the base plate 1.
[0037] The second rubber pad 18 is fixedly connected to one side of the clamping block 17 away from the second threaded rod 15 . Both the clamping block 17 and the second rubber pad 18 are arranged in an arc shape. The shape of the clamping block 17 matches the shape of the pile body 2 .
[0038] In addition, an auxiliary rod 19 is fixedly connected to one side of the clamping block 17 away from the rubber pad 18 , one end of the auxiliary rod 19 passes through the threaded block 14 , and the auxiliary rod 19 is slidably connected to the threaded block 14 .
[0039] When the pile body 2 is clamped, the hand wheel 16 is first rotated to drive the threaded rod 15 to rotate, and the threaded rod 15 rotates to drive the clamping block 17 to move. When the clamping block 17 moves, it will be close to the pile body 2, so that the clamping block 17 clamps and fixes the pile body 2. After the clamping block 17 clamps and fixes the pile body 2, the movement and shaking of the pile body 2 can be effectively reduced, which is beneficial to maintaining the verticality and position stability of the pile body 2, thereby improving the accuracy and efficiency of the construction process. When the clamping block 17 clamps the pile body 2, the friction between the clamping block 17 and the pile body 2 can be increased by the rubber pad 18, and the fixing effect of the clamping block 17 is further improved. The clamping block 17 and the rubber pad 18 are both set to be semicircular, so that the contact area between the clamping block 17 and the rubber pad 18 and the pile body 2 is larger. When the clamping block 17 is moving, the auxiliary rod 19 is used to provide the clamping block 17 with an additional support point, so that the clamping block 17 is more stable when moving.
[0040] Reference Figure 2 and Figure 3 The top of the threaded block 14 is fixedly connected to a rotating seat 20, the interior of the rotating seat 20 is rotatably connected to a slide cylinder 21, the interior of the slide cylinder 21 is slidably connected to a slide rod 22, the end of the slide rod 22 away from the slide cylinder 21 is rotatably connected to a rotating seat 23, and the side of the rotating seat 23 away from the slide rod 22 is fixedly connected to the clamping block 17.
[0041] A through hole is formed on one side of the slide cylinder 21 , and a bolt 24 is slidably disposed inside the through hole. A plurality of thread grooves 25 are formed at equal intervals on one side of the slide rod 22 , and the bolt 24 is threadedly connected to the thread grooves 25 .
[0042] When the clamping block 17 moves, the clamping block 17 is fixedly connected to the rotating seat 23, so that the rotating seat 23 moves, and then the rotating seat 23 is rotationally connected to the slide rod 22, so that the slide rod 22 slides inside the slide cylinder 21, and a stable triangle is formed between the clamping block 17 and the substrate 1 through the slide rod 22 and the slide cylinder 21, thereby ensuring the clamping effect of the clamping block 17, and when the slide rod 22 slides to a suitable position, the bolt 24 is placed in the through hole of the slide cylinder 21, and then the bolt 24 is threadedly connected to the thread groove 25, so as to fix the position of the slide rod 22, thereby ensuring the supporting force of the slide cylinder 21 and the slide rod 22.
[0043] Reference Figure 1 , Figure 2 and Figure 4 The reinforcement mechanism includes a plurality of reinforcement boxes 4 which are fixedly connected to the top of the base plate 1 at equal intervals, and a rotating shaft 5 is fixedly connected to both sides of the interior of the reinforcement box 4. A rotating plate 6 is rotatably connected to the outer surface of the rotating shaft 5. An insertion rod 7 is slidably arranged inside the rotating plate 6, and a striking block 8 is fixedly connected to the top of the insertion rod 7. The bottom end of the insertion rod 7 passes through the rotating plate 6 and is arranged in a cone shape. A limiting member is arranged on one side of the reinforcement box 4.
[0044] Among them, the limiting part includes a threaded rod 9 threadedly connected to one side of the reinforcement box 4, one end of the threaded rod 9 is fixedly connected to a handle 10, the end of the threaded rod 9 away from the handle 10 penetrates the reinforcement box 4 and is rotatably connected to a fixed block 11, and the side of the fixed block 11 away from the threaded rod 9 is fixedly connected to a rubber pad 12.
[0045] After installing the base plate 1, the staff first rotates the rotating plate 6 to a suitable angle, then places the insertion rod 7 inside the rotating plate 6, and then uses a tool to hammer the striking block 8. The striking block 8 moves downward under the force, and the downward movement of the striking block 8 will drive the insertion rod 7 to move inside the rotating plate 6, and then the bottom end of the insertion rod 7 is set to a cone so that the insertion rod 7 enters the foundation. By inserting the insertion rod 7 into the foundation, the connection area between the base plate 1 and the foundation can be increased, and the stability and bearing capacity of the overall base plate 1 can be improved, thereby ensuring the stability of the pile body 2. During transportation, the fixed block 11 and the rubber pad 12 are driven to move inside the reinforcement box 4 by rotating the threaded rod 9, so that the fixed block 11 and the rubber pad 12 limit the rotating plate 6. The limiting effect of the fixed block 11 and the rubber pad 12 can effectively fix the position of the rotating plate 6, reduce its loosening or movement during transportation, thereby reducing the wear and collision risks of the rotating plate 6 and other components.
[0046] Working principle: Drill a hole at a suitable position of the foundation, and then use a crane to place the pile body 2 in the drilled hole. Before placing the steel cage 3, it is usually necessary to clean the pile bottom, and then use a crane to place the steel cage 3 into the interior of the pile body 2, and then pour cement mortar into the interior of the pile body 2, and then use an instrument to detect the verticality of the steel cage 3 to ensure that the position and direction of the steel cage 3 meet the design requirements. Finally, wait for the cement mortar in the bored pile to solidify and meet the strength requirements before completing the bored pile construction. Turn the handwheel 16 to drive the threaded rod 15 to rotate, and the rotation of the threaded rod 15 drives the clamping block 17 to move. When the clamping block 17 moves, it will be tightly attached to the pile body 2, so that the clamping block 17 clamps and fixes the pile body 2. The friction between the clamping block 17 and the pile body 2 can be increased by the rubber pad 18, further improving the fixing effect of the clamping block 17. When the holding block moves, the auxiliary rod 19 provides an additional support point for the clamping block 17.
[0047] First, rotate the rotating plate 6 to a suitable angle, then place the insertion rod 7 inside the rotating plate 6, and then use a tool to hammer the striking block 8, so that the striking block 8 moves downward under the force. The downward movement of the striking block 8 will drive the insertion rod 7 to move inside the rotating plate 6, and then set the bottom end of the insertion rod 7 to a cone so that the insertion rod 7 enters the foundation. By inserting the insertion rod 7 into the foundation, the connection area between the base plate 1 and the foundation can be increased.
