Description

Technical Field

[0001] This utility model relates to the field of concrete cast-in-place pile construction technology, specifically to a concrete cast-in-place pile foundation construction device. Background Technology

[0002] Concrete cast-in-place piles are a common type of deep foundation, widely used in foundation treatment of buildings. They are formed by pouring concrete into pre-drilled holes and have advantages such as high load-bearing capacity and strong adaptability.

[0003] Currently, during the construction of cast-in-place concrete piles, a grouting guide pipe is inserted into a pre-drilled hole, and then concrete is poured into the guide pipe. However, the existing cast-in-place concrete pile construction equipment is not convenient for fixing the grouting guide pipe, which makes it easy for the guide pipe to tilt when pouring into the hole, resulting in uneven concrete pouring and affecting the construction quality of the cast-in-place concrete pile.

[0004] Therefore, it is necessary to provide a new concrete cast-in-place pile foundation construction device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a concrete pile foundation construction device that fixes the grouting conduit.

[0006] The concrete pile foundation construction device provided by this utility model includes a grouting pipe inserted into the foundation body. Two reinforcement seats are provided on the top of the foundation body in a symmetrical arrangement. A vertical plate is fixed on the top of each of the two reinforcement seats. A clamping mechanism for the grouting pipe is provided on one side of the vertical plate.

[0007] The clamping mechanism includes an arc-shaped clamping plate disposed on one side of the vertical plate. Two arc-shaped connecting plates symmetrically distributed vertically are fixedly connected to one side of the arc-shaped clamping plate. A movable plate is fixedly connected to one end of each of the two arc-shaped connecting plates. A circular plate is disposed between the two arc-shaped connecting plates. A threaded rod is fixed to the other side of the circular plate. One end of the threaded rod is inserted into a through hole in the movable plate. The other end of the threaded rod extending out of the through hole is screwed into a threaded hole in the vertical plate. A screw cap is fixedly connected to the other end of the threaded rod extending out of the threaded hole.

[0008] A friction pad is fixedly connected to one end of the circular plate, and the friction pad abuts against the arc-shaped clamping plate.

[0009] Several guide rods are fixed on one side of the movable plate. One end of each guide rod is inserted into a sliding hole in the vertical plate, and the end of the guide rod extending out of the sliding hole is fixedly connected to a limiting plate.

[0010] The bottom of the reinforcement base has two sets of grooves that are symmetrically distributed from left to right. A tapered rod is provided inside the groove, and a movable shaft is provided on the tapered rod. The two ends of the movable shaft extending out of the tapered rod are fixedly connected to the inner wall of the groove.

[0011] Two assembly plates are fixed on one side of the reinforcement base. The assembly plate is inserted into the assembly slot of the other reinforcement base. The top of the other reinforcement base is provided with a fixing bolt. The fixing bolt passes through the insertion hole of the other reinforcement base and is screwed into the threaded groove of the top of the assembly plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This concrete pile foundation construction device can fix the grouting guide pipe inserted into the hole, making it less prone to tilting and ensuring more uniform concrete pouring. It effectively improves the construction quality of the concrete pile and solves the problem that existing concrete pile construction devices are not easy to fix the grouting guide pipe, which makes the guide pipe prone to tilting when pouring concrete into the hole, resulting in uneven concrete pouring and affecting the construction quality of the concrete pile.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A structural schematic diagram of the concrete cast-in-place pile foundation construction device provided by this utility model; Figure 2 This is a schematic diagram of the clamping mechanism of this utility model; Figure 3 This is a top view of the connection between the two reinforcing bases of this utility model; Figure 4 This is a schematic diagram of the reinforcing base structure of this utility model; Figure 5 This is a perspective view of the clamping mechanism of this utility model. A concrete cast-in-place pile foundation construction device includes a grouting conduit 2 inserted into a foundation body 1. Two symmetrically distributed reinforcing seats 3 are provided on the top of the foundation body 1. A vertical plate 4 is fixed to the top of each reinforcing seat 3. A clamping mechanism for the grouting conduit 2 is provided on one side of the vertical plate 4. The clamping mechanism includes an arc-shaped clamping plate 401 on one side of the vertical plate 4. Two symmetrically distributed arc-shaped connecting plates 402 are fixedly connected to one side of the arc-shaped clamping plate 401. A movable plate 403 is fixedly connected to one end of each of the two arc-shaped connecting plates 402. A circular plate 404 is provided between the two arc-shaped connecting plates 402. A threaded rod 405 is fixed to the other side of the circular plate 404. One end of the threaded rod 405 is inserted into a through hole 406 in the movable plate 403. The other end of the threaded rod 405 extending out of the through hole 406 is screwed into a threaded hole 407 in the vertical plate 4. A cap 408 is fixedly connected to the other end of the threaded rod 405 extending out of the threaded hole 407.

[0022] Using the above technical solution, the grouting conduit 2 is inserted into the pre-drilled hole in the foundation body 1. Then, two reinforcing seats 3 are installed on the top of the foundation body 1. The cap 408 on one side of the vertical plate 4 is rotated, which drives the threaded rod 405 to rotate in the threaded hole 407. The threaded connection between the threaded rod 405 and the threaded hole 407 causes the threaded rod 405 to drive the circular plate 404 to move toward the grouting conduit 2. The circular plate 404 drives the arc-shaped clamping plate 401 to move synchronously, so that the arc-shaped clamping plate 401 abuts against the grouting conduit 2. Similarly, the other arc-shaped clamping plate 401 can be adjusted. The two arc-shaped clamping plates 401 can fix the grouting conduit 2, making it less likely for the grouting conduit 2 to tilt in the hole, making the concrete grouting more uniform, and effectively improving the construction quality of the concrete grouting pile.

[0023] Reference Figure 2 and Figure 5 A friction pad 409 is fixedly connected to one end of the circular plate 404. The friction pad 409 abuts against the arc-shaped clamping plate 401. The friction pad 409 is used to increase the friction between the circular plate 404 and the arc-shaped clamping plate 401, so that the circular plate 404 is more firmly and reliably pressed and fixed to the arc-shaped clamping plate 401.

[0024] Reference Figure 2 and Figure 5 Several guide rods 410 are fixed on one side of the movable plate 403. One end of the guide rod 410 is inserted into the sliding hole 411 opened in the vertical plate 4. The guide rod 410 extends out of the sliding hole 411 and is fixedly connected to the limiting plate 412. When the arc-shaped clamping plate 401 moves, it drives the movable plate 403 to move. When the movable plate 403 moves, the guide rod 410 on one side slides in the sliding hole 411. The movement of the movable plate 403 is limited by the guide rod 410, making the movable plate 403 more stable during the movement.

[0025] Reference Figure 1 The bottom of the reinforcement base 3 has two sets of grooves 301 that are symmetrically distributed from left to right. A tapered rod 302 is provided inside the groove 301. A movable shaft 303 is provided on the tapered rod 302. The two ends of the movable shaft 303 extending out of the tapered rod 302 are fixedly connected to the inner wall of the groove 301. The tapered rod 302 inside the groove 301 is rotated, and then the tapered rod 302 is inserted into the foundation body 1. The reinforcement base 3 can be fixed to the top of the foundation body 1 through the tapered rod 302.

[0026] Reference Figure 3 and Figure 4 Two assembly plates 304 are fixed to one side of the reinforcement base 3. The assembly plates 304 are inserted into the assembly slots 305 opened in the other reinforcement base 3. The top of the other reinforcement base 3 is provided with fixing bolts 306. The fixing bolts 306 pass through the insertion holes 307 opened in the other reinforcement base 3 and are screwed into the threaded grooves 308 opened in the top of the assembly plates 304. The assembly plates 304 on one side of the reinforcement base 3 are inserted into the assembly slots 305 opened in the other reinforcement base 3. Then, the bottom end of the fixing bolts 306 passes through the insertion holes 307 and is screwed into the threaded grooves 308. The assembly plates 304 can be fixed in the assembly slots 305 by the cooperation of the fixing bolts 306 and the threaded grooves 308, thereby fixing the two reinforcement bases 3 together. Similarly, the two reinforcement bases 3 can also be separated and stored, making the use of the reinforcement bases 3 more convenient.

[0027] The implementation principle of a concrete cast-in-place pile foundation construction device according to this utility model embodiment is as follows: the grouting conduit 2 is inserted into a pre-drilled hole in the foundation body 1, and then two reinforcing seats 3 are installed on the top of the foundation body 1. The cap 408 on one side of the vertical plate 4 is rotated, and the cap 408 drives the threaded rod 405 to rotate in the threaded hole 407. The threaded connection between the threaded rod 405 and the threaded hole 407 causes the threaded rod 405 to drive the circular plate 404 to move towards the grouting conduit 2. The circular plate 404 drives the arc-shaped clamping plate 401 to move synchronously, so that the arc-shaped clamping plate 401 abuts against the grouting conduit 2. Similarly, the other arc-shaped clamping plate 401 can be adjusted. The two arc-shaped clamping plates 401 can fix the grouting conduit 2, making it less likely for the grouting conduit 2 to tilt in the hole, making the concrete grouting more uniform, and effectively improving the construction quality of the concrete cast-in-place pile.
