Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a pile foundation reinforcement and protection device for highway construction. Background Art

[0002] At present, a Chinese utility model with the announcement number: CN216810045U discloses a pile foundation reinforcement and protection device for highway construction, including a reinforcement plate, an adjustment component is arranged on the outer side of one end of the reinforcement plate, the adjustment component includes a first connecting plate, a first gear, a first rotating shaft, a support plate, a second rotating shaft, a second gear, a second connecting plate and a bottom plate, the outer side of one end of the reinforcement plate is fixedly connected to the outer side of one end of the first connecting plate, the inner side of one end of the first connecting plate is rotatably connected to the outer side of one end of the No. 1 gear, and the inner side of one end of the No. 1 gear is fixedly connected to the outer side of one end of the first rotating shaft. The reinforcement position can be adjusted by the adjustment component to avoid the situation where each reinforcement needs to be customized separately, thereby speeding up the construction progress and reducing the construction cost. The fast engagement through the engagement component can save time and effort, speed up the construction progress and reduce the construction cost.

[0003] The above patent utilizes a spring to push the block to get stuck into the teeth of the gear, thereby limiting and fixing the rotating shaft. In this fixing method, the fixing force of the rotating shaft comes from the spring. Therefore, when the external force is sufficient to overcome the elastic force of the spring, the block will be separated from the teeth of the gear, causing the rotating shaft and the support plate to rotate unexpectedly, so the stability is poor; at the same time, although the existing pile foundation protection has good sealing performance and rainwater will not leak from the gap between the pile foundation and the protective device, rainwater will still drip directly to the vicinity of the pile foundation, which will cause soil erosion over a long period of time, thereby causing the foundation around the pile foundation to sink, affecting the stability of the pile foundation. Utility Model Content

[0004] The purpose of the utility model is to provide a pile foundation reinforcement and protection device for highway construction, which has the advantages of not only being able to adjust the reinforcement and protection device, but also improving the stability of the adjustment and preventing rainwater from dripping onto the land around the pile foundation, thereby avoiding soil erosion and causing foundation settlement.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a pile foundation reinforcement and protection device for highway construction, comprising a first arc-shaped plate and a second arc-shaped plate, a fixing plate is provided on the side of the first arc-shaped plate and the second arc-shaped plate away from each other, a fixing sleeve is installed on the top of the two fixing plates and the side of the first arc-shaped plate and the second arc-shaped plate away from each other, the fixing sleeve is internally rotatably connected to a support rod, the fixing sleeve is internally rotatably connected to a gear fixedly sleeved with one end of the support rod, the top of the fixing sleeve is threadedly connected to a bolt, and the bottom of the bolt is fixedly connected to a bevel tooth engaged with the gear.

[0006] With the above technical solution, by utilizing the frictional force of the screw thread engagement between the bolt and the fixing sleeve, the bevel gear can be stuck on the surface of the gear to fix the support rod and prevent it from rotating. When the support rod needs to be rotated, only the setting of rotating the bolt in the reverse direction to drive the bevel gear to move upward is required. Thus, not only can the reinforcement protection device be adjusted, but also the stability of the adjustment can be improved to prevent accidental rotation. The first semi-circular cover and the second semi-circular cover are used to catch and store the water droplets dripping from the top near the pile foundation. At the same time, the conical baffle is set to prevent rainwater from seeping between the pile foundation and the semi-circular insertion pipe. Then, through the drain pipe, the water stored inside the first semi-circular cover and the second semi-circular cover is discharged to a distance. Thereby, it is possible to prevent rainwater from dripping onto the land around the pile foundation and avoid soil erosion causing foundation settlement.

[0007] The present utility model is further configured as follows: The top of the first arc-shaped plate and the second arc-shaped plate are symmetrically and fixedly connected with a first semi-circular cover and a second semi-circular cover respectively.

[0010] With the above technical solution, it is convenient to insert the inserting tooth rods into the soil, thereby improving the stability of the pile foundation protection.

[0011] The present utility model is further configured as follows: Limiting sliding grooves that are clamped with the semi-circular insertion pipes are respectively opened inside the first arc-shaped plate and the second arc-shaped plate.

[0012] With the above technical solution, it is convenient for positioning and installing between the first arc-shaped plate and the second arc-shaped plate and the semi-circular insertion pipe.

[0013] The present utility model is further configured as follows: The docking gap directions of the first arc-shaped plate and the second arc-shaped plate and the first semi-circular cover and the second semi-circular cover are opposite.

[0014] With the above technical solution, the stability and sealing performance of the installation of the first semi-circular cover and the second semi-circular cover between the first arc-shaped plate and the second arc-shaped plate are improved.

[0015] The present utility model is further configured as follows: Sealing stickers are bonded on the inside of the first semi-circular cover and the second semi-circular cover and the surfaces of the two conical baffles.

[0016] By adopting the above technical solution, the sealing performance between the first semi-circular cover and the second semi-circular cover is improved, preventing water from seeping out therefrom.

[0017] The present utility model is further configured as follows: Both sides inside the first arc-shaped plate are slidably connected with Z-shaped clamping rods. A spring is fixedly installed inside the first arc-shaped plate. One end of each of the two Z-shaped clamping rods close to each other is fixedly connected to both ends of the spring respectively. A clamping groove for clamping with the Z-shaped clamping rod is formed inside the second arc-shaped plate. One end of the Z-shaped clamping rod close to the first arc-shaped plate is fixedly connected with a pressing rod that penetrates and slidably connects with the first arc-shaped plate.

[0018] By adopting the above technical solution, the spring is contracted by pressing the pressing rod, so that the Z-shaped clamping rod can move backward. Then, the first arc-shaped plate and the second arc-shaped plate are attached to each other, so that the Z-shaped clamping rod extends into the clamping groove. Then, the pressing rod is released, and the Z-shaped clamping rod is snapped into the clamping groove by the resilience of the spring, thereby clamping and fixing the first arc-shaped plate and the second arc-shaped plate together.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. By utilizing the frictional force of the threaded engagement between the bolt and the fixed sleeve, the bevel gear can be locked on the surface of the gear to fix the support rod and prevent it from rotating. When the support rod needs to be rotated, only by reversely rotating the bolt to drive the bevel gear to move upward, not only can the reinforcement protection device be adjusted, but also the stability of the adjustment can be improved, preventing accidental rotation.
