Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a post-grouting pile head structure for rock-socketed piles. Background Technique
[0002] A rotary drilled pile refers to a pile type constructed by a rotary drilling rig, and its full name is a rotary drilled cast-in-place pile. When the rotary drilling rig forms a hole, first, a bucket-type drill bit with a valve at the bottom rotates to break the rock and soil, and directly loads it into the drill bucket. Then, the drill bucket is lifted out of the hole by the lifting device and telescopic drill pipe of the drilling rig to unload the soil. The process of taking and unloading soil is repeated until the designed depth is drilled. In karst areas, rotary cast-in-place piles are mostly used for pile foundation construction, and when necessary, the pile foundation bearing capacity can be improved through the post-grouting process at the pile bottom, greatly improving economic benefits.
[0003] The prior art such as the utility model with the publication number of CN215367223U discloses a post-grouting pile head structure for rock-socketed piles. This patent uses a pile hole, in which a pile body is arranged. Below the pile top of the pile body is a super-grouting area, and between the pile top of the pile body and the ground is an empty pile treatment area. The pile body includes a plurality of pile longitudinal bars arranged in a ring shape. Spiral stirrups are arranged on the plurality of pile longitudinal bars in the super-grouting area. There are two grouting pipes, left and right, arranged on the spiral stirrups. The plurality of pile longitudinal bars are provided with a plurality of additional fixed stirrups at intervals up and down in the empty pile treatment area. The two grouting pipes, left and right, are connected to the plurality of additional fixed stirrups. The first concrete is poured in the super-grouting area, and the second concrete is poured in the empty pile treatment area. The equipment of the utility model solves the problems that the traditional post-grouting process simply leaves a grouting pipe at the pile top and grouts after the grouting node, without effectively protecting the grouting pipe, and there are no requirements for the empty pile area from the designed pile top to the ground of the construction site.
[0004] In daily work, during the process of using the equipment for grouting, there is one end of the grouting pipe protruding above the ground. Generally, users use the way of winding for manual marking, and manually wind the marking tape around the surface of the grouting pipe for marking. However, the manual winding is too cumbersome, resulting in low work efficiency of the operator. Content of the Utility Model
[0005] The purpose of the utility model is to propose a post-grouting pile head structure for rock-socketed piles to solve the defect that the manually wound marking tape is easy to fall off in the prior art.
[0006] To achieve the above object, the utility model adopts the following technical solutions: A post-grouting pile head structure for rock-socketed piles, including the ground, a grouting pipe, a marking ring, and a fixing device. The grouting pipe is arranged inside the ground. One end of the grouting pipe is provided with a marking ring. The fixing device is arranged on the side of the grouting pipe. The fixing device includes a limiting groove and a resisting ring. The resisting ring is fixedly connected to the surface of the grouting pipe. The marking ring abuts against the surface of the resisting ring. The limiting groove is opened on the side of the grouting pipe. A limiting block is fixedly connected inside the marking ring. The limiting block is clamped with the inner wall of the limiting groove. A fixing groove is opened on the surface of the marking ring. A connecting block is fixedly connected to the side of the grouting pipe. A pulling groove is opened on the surface of the connecting block.
[0007] Further, a sliding rod is fixedly connected to the inner wall of the pulling groove. A sliding plate is sleeved and slidably connected to the surface of the sliding rod. By setting the sliding rod, the sliding plate can be limited and moved, reducing the situation that the sliding plate is easily separated from the inner wall of the pulling groove during the use of the device, resulting in the fixing rod being difficult to fix the marking ring.
[0008] Further, a fixing rod is fixedly connected to one end of the sliding plate. The fixing rod is clamped with the inner wall of the fixing groove. Setting the fixing rod facilitates positioning the marking ring.
[0009] Further, a spring is sleeved and connected to the surface of the sliding rod. Two ends of the spring are respectively fixedly connected to the surface of the sliding plate and the inside of the pulling groove. By setting the spring, it is convenient to apply a reset elastic force to the sliding plate.
[0010] Further, a cleaning device is arranged on the side of the marking ring. The cleaning device includes a first connecting frame and a second connecting frame. The two first connecting frames are fixedly connected to the bottom side of the marking ring. The two second connecting frames are fixedly connected to the top end of the marking ring. A limiting column is fixedly connected between the first connecting frame and the second connecting frame. A threaded rod is rotatably connected between the first connecting frame and the second connecting frame. A cleaning ring is threadedly connected to the surface of the threaded rod. A connecting cap is fixedly connected to one end of the threaded rod. By setting the cleaning ring, the surface of the marking ring can be cleaned, reducing the situation that the surface of the marking ring is easily adsorbed with mud during the use of the device, resulting in the marking ring being difficult to play a marking role.
[0011] Further, one end of the cleaning ring is slidably connected to the surface of the limiting column. A motor is fixedly connected to one end of the threaded rod. Setting the threaded rod facilitates moving the cleaning ring.
[0012] Further, a base is fixedly connected to the side of the motor. The base is fixedly connected to the surface of the first connecting frame. Setting the base facilitates limiting the motor.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0014] 1. In this utility model, when the device is in use, the user installs the irrigation pipe on the ground and then irrigates the inside of the irrigation pipe. When the device is in use, the user pulls the sliding plate. Then, when the sliding plate moves, it drives the fixed rod to move. When the sliding plate moves, it drives the spring to displace and deform to generate elastic force. Then, when the sliding plate moves, it drives the fixed rod to move out of the inside of the fixed groove. Then, the identification ring loses its restraint, and pulling the identification ring to move drives the limit block to move out of the inside of the limit groove. By setting the fixing device, the identification ring is effectively fixed, playing a role in limiting and fixing the identification ring, reducing the situation that when the device is in use, the general user uses the winding method to wind the identification tape on the surface of the grouting pipe for identification. However, manual winding is too cumbersome and not fixed enough, which easily causes low work efficiency of the operator and the identification tape to break away from the surface of the grouting pipe, improving the practicability of the device.
[0015] 2. In this utility model, by setting the cleaning device, when the device is in use, the user starts the motor, and then the motor rotates to rotate the threaded rod. When the threaded rod rotates, it drives the cleaning ring to move. Then, when the cleaning ring moves, it cleans the surface of the identification ring. By setting the cleaning device, the surface of the identification ring is effectively cleaned, playing a role in cleaning the surface of the identification ring, reducing the situation that when the device is in use, since the device is installed and used at the construction site where the environment is poor, the surface of the identification ring is easily adsorbed with mud, resulting in the identification ring being difficult to play the role of identification, improving the practicability of the device.

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a post-grouting pile head structure for rock-socketed piles, including a ground 1, a grouting pipe 2, an identification ring 3 and a fixing device 4. A grouting pipe 2 is arranged inside the ground 1, and an identification ring 3 is arranged at one end of the grouting pipe 2.
[0023] Next, specifically describe the specific settings and functions of its fixing device 4 and cleaning device 5.
[0024] In this implementation: The fixing device 4 is arranged on the side of the grouting pipe 2. The fixing device 4 includes a limiting groove 41 and a contact ring 410. The contact ring 410 is fixedly connected to the surface of the grouting pipe 2. The identification ring 3 is in contact with the surface of the contact ring 410. The limiting groove 41 is opened on the side of the grouting pipe 2. A limiting block 42 is fixedly connected inside the identification ring 3. The limiting block 42 is clamped with the inner wall of the limiting groove 41. A fixing groove 43 is opened on the surface of the identification ring 3. A connecting block 44 is fixedly connected to the side of the grouting pipe 2. A pulling groove 45 is opened on the surface of the connecting block 44.
[0025] Specifically, a slide bar 46 is fixedly connected to the inner wall of the pulling groove 45, and a slide plate 47 is sleeved and slidably connected to the surface of the slide bar 46.
[0026] In this embodiment: By setting the slide bar 46, the limiting movement of the slide plate 47 can be realized, reducing the situation that the slide plate 47 is easily separated from the inner wall of the pulling groove 45 during the use of the equipment, resulting in the difficulty of the fixing rod 48 to fix the identification ring 3.
[0027] Specifically, a fixing rod 48 is fixedly connected to one end of the slide plate 47. The fixing rod 48 is clamped with the inner wall of the fixing groove 43. Setting the fixing rod 48 facilitates the positioning of the identification ring 3.
[0028] Specifically, a spring 49 is sleeved and connected to the surface of the slide bar 46. The two ends of the spring 49 are respectively fixedly connected to the surface of the slide plate 47 and the inside of the pulling groove 45. By setting the spring 49, it is convenient to apply a reset elastic force to the slide plate 47.
[0029] In this embodiment: a cleaning device 5 is provided on the side of the identification ring 3, and the cleaning device 5 includes a first connecting frame 51 and a second connecting frame 52. The two first connecting frames 51 are fixedly connected to the bottom side of the identification ring 3, and the two second connecting frames 52 are fixedly connected to the top of the identification ring 3. A limiting column 58 is fixedly connected between the first connecting frame 51 and the second connecting frame 52. A threaded rod 53 is rotatably connected between the first connecting frame 51 and the second connecting frame 52. The surface of the threaded rod 53 is threadedly connected to a cleaning ring 54, and one end of the threaded rod 53 is fixedly connected to a connecting cap 57.
[0030] In this embodiment, by providing a cleaning ring 54, the surface of the identification ring 3 can be cleaned, thereby reducing the situation where the surface of the identification ring 3 is easily adsorbed with mud when the equipment is in use, making it difficult for the identification ring 3 to play an identification role.
[0031] Specifically, one end of the cleaning ring 54 is slidably connected to the surface of the limiting column 58, and one end of the threaded rod 53 is fixedly connected to the motor 55. The threaded rod 53 is provided to facilitate the movement of the cleaning ring 54.
[0032] Specifically, the side of the motor 55 is fixedly connected to the base 56 , and the base 56 is fixedly connected to the surface of the first connecting frame 51 . The base 56 is provided to facilitate the limiting of the motor 55 .
[0033] Working principle: When the equipment is in use, the user installs the irrigation pipe on the ground 1, and then irrigates the inside of the irrigation pipe. When the equipment is in use, the user pulls the slide plate 47, and then when the slide plate 47 moves, it drives the fixing rod 48 to move. When the slide plate 47 moves, it drives the spring 49 to displace and deform to generate elastic force, and then the slide plate 47 moves to drive the fixing rod 48 to move out of the fixing groove 43, and then the identification ring 3 loses its restraint, and the identification ring 3 is pulled to move and drive the limit block 42 to move out of the limit groove 41. By setting the fixing device 4, the identification ring is effectively fixed, which plays a role in limiting and fixing the identification ring 3, reducing the use of the equipment. Generally, users use the winding method to wrap the identification tape around the surface of the grouting pipe 2 for identification. However, manual winding is too cumbersome and not fixed enough, which can easily cause low work efficiency of the operator and the situation where the identification tape is separated from the surface of the grouting pipe 2, thereby improving the practicability of the equipment.
[0034] When the equipment is in use, the user starts the motor 55, and then the motor 55 rotates the threaded rod 53 to rotate. When the threaded rod 53 rotates, it drives the cleaning ring 54 to move, and then when the cleaning ring 54 moves, the surface of the identification ring 3 is cleaned. By setting up the cleaning device 5, the surface of the identification ring 3 is effectively cleaned, which plays a role in cleaning the surface of the identification ring 3. When the equipment is in use, the equipment is installed and used at a construction site with a poor construction site environment. The surface of the identification ring 3 is easy to absorb mud, making it difficult for the identification ring 3 to play a role, thereby improving the practicability of the equipment.
