[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5 As shown, a highway bridge pile foundation reinforcement device comprises a pile body 1 and a reinforcement platform 2 fixedly installed on the bottom surface of the pile body 1, two groups of clamping components are respectively sleeved on the lower end of the pile body 1, the clamping components comprise a support ring 3, an extension ring 11 is fixedly installed on the upper end surface of the support ring 3, a fixing ring 12 is slidably installed on the outer wall of the extension ring 11, wherein a plurality of support rods 4 are equidistantly rotatably installed on the bottom surface of the support ring 3 arranged above, and the lower ends of the plurality of support rods 4 are rotatably connected with adjustment blocks 5, a hydraulic push rod 6 is arranged between the support ring 3 arranged below and the plurality of adjustment blocks 5, and the two ends of the hydraulic push rod 6 are respectively fixedly connected to the corresponding positions on the outer wall of the adjustment block 5 and the support ring 3, a lifting platform 7 is fixedly connected to the bottom surface of the reinforcement platform 2, and a plurality of groups of protective components are arranged on the outer wall of the lifting platform 7;

[0026] After the pile body 1 is installed on the lifting platform 7, the construction personnel can pour concrete at the connection between the pile body 1 and the lifting platform 7 to make a reinforcement platform 2. Then, the construction personnel can install the clamping assembly composed of two semicircular structures on the outer wall of the lower end of the foundation pile according to the height of the foundation pile. When the clamping assembly is installed, the inner wall of the support ring 3 and the extension ring 11 fixedly installed on the support ring 3 are in close contact with the outer wall of the foundation pile. Then, the clamping assembly can be clamped on the outer wall of the foundation pile through the fixing ring 12. When installing the two clamping assemblies, the support set at the lower end of the pile body 1 The multiple hydraulic push rods 6 connected to the outer wall of the ring 3 are synchronously adjusted according to the distance between the two clamping components, so that a stable triangular structure is formed between the hydraulic push rods 6, the pile body 1 and the support rod 4 to support the lower end of the pile body 1, and the lower end of the pile body 1 can be reinforced to prevent cracks inside the lower end of the pile body 1 from affecting the normal support of the pile body 1. At the same time, the multiple protective components arranged outside the lifting platform 7 can buffer the impact force of the outside on the lifting platform 7 to prevent damage to the lifting platform 7 and the pile body 1 caused by collisions with external vehicles and ships.

[0027] like Figure 1 , 3 As shown in Figure 4, the protection component includes a hydraulic airbag 8 fixedly connected to the outer wall of the lower end of the lifting platform 7, and the end of the hydraulic airbag 8 is fixedly connected to an anti-collision plate 9. When a vehicle or a ship loses control and collides with the lifting platform 7, it preferentially contacts the anti-collision plate 9 arranged on the outer peripheral side of the lifting platform 7. Under the buffering effect produced by the elastic deformation of the hydraulic airbag 8 arranged between the lifting platform 7 and the anti-collision plate 9, the impact force of the ship or vehicle on the lifting platform 7 and the pile body 1 installed on the lifting platform 7 is reduced, thereby preventing a large number of ships and vehicles from damaging the pile body 1.

[0028] like Figure 3 and Figure 4 As shown, the protection component also includes a slider 10 fixedly connected to the upper end of the anti-collision plate 9, and the other end of the slider 10 is slidably connected to the upper end of the lifting platform 7. The outer wall of the end of the slider 10 located in the lifting platform 7 is fixedly connected with a trigger rod 13, and an extrusion switch is arranged at a position corresponding to the end of the trigger rod 13 inside the lifting platform 7. When the outer wall of the anti-collision plate 9 is squeezed and hit, the hydraulic airbag 8 arranged between the anti-collision plate 9 and the lifting platform 7 plays a preliminary buffering role. At the same time, the slider 10 connected to the anti-collision plate 9 slides toward the inside of the lifting platform 7, and the trigger rod 13 fixedly connected to the slider 10 triggers the extrusion switch in the lifting platform 7. Then, after the extrusion switch is turned on, the hydraulic airbag 8 can further expand to buffer the impact force of the ship or vehicle, thereby avoiding damage to the lifting platform 7 and the pile body 1 installed on the lifting platform 7 due to violent collision.

[0029] like Figure 4As shown, a groove is provided on the upper end surface of the slider 10, and a plurality of tooth blocks 15 are fixedly installed on the bottom surface of the groove. A reset gear 14 meshingly connected with the tooth block 15 is rotatably installed on the bottom surface of the reinforcement platform 2 at a position corresponding to the groove. After the impacted vehicle or ship is removed, the reset gear 14 can be rotated to allow the slider 10 to slide outward to restore to its initial position under the meshing action of the reset gear 14 and the tooth block 15, so that the protective component is restored to the protective state.

[0030] like Figure 5 As shown, two sets of mounting holes are formed at both ends of the fixing ring 12, and fastening bolts are rotatably connected inside the mounting holes. The two sets of fastening bolts distributed up and down can make the ends of the fixing ring 12 connected more tightly, and can also make the inner walls of the support ring 3 and the extension ring 11 fit more closely with the outer wall of the pile body 1.

[0031] like Figure 4 As shown, the lifting platform 7 is a structure that is wide at the top and narrow at the bottom, and the cross section of the lifting platform 7 is a positive multi-deformation setting. The special structure of the lifting platform 7 can increase the contact area between the lower end of the pile body 1 and the installation position, making the lower end of the pile body 1 more stable after installation.

[0032] like Figure 1 As shown, the number of support rods 4 and protection components is the same, and is not less than six groups. The support rods 4 and protection components are evenly distributed around the pile body 1. After 9 of the multiple protection components are combined, various directions of the lifting platform 7 can be protected, so that the multiple protection components have a better protection effect on the lifting platform 7.

[0033] The working principle of the utility model is as follows: during use, after the pile body 1 is installed on the lifting platform 7, the construction personnel can pour the reinforcement platform 2 composed of concrete at the lower end of the pile body 1, and the connection between the pile body 1 and the lifting platform 7 can be reinforced under the action of the reinforcement platform 2. Then, the construction personnel can fit the support ring 3 and the extension ring 11 in the two clamping components to the outer wall of the pile body 1, and then fix the fixing ring 12 through the fastening bolts in the mounting holes opened at the end of the fixing ring 12, and the two sets of clamping components can be installed at the corresponding positions of the outer wall of the lower end of the pile body 1. The construction personnel can adjust the distance between the two clamping components according to the actual height of the foundation pile. When adjusting the distance between the two clamping components, the lengths of multiple hydraulic push rods 6 are adjusted, so that the support rods 4 are evenly distributed on the surrounding side of the pile body 1 to support the foundation pile. When the pile body 1 is put into use, if a large ship or vehicle loses control and hits the lifting platform 7, it will give priority to the distribution on the outer wall of the lifting platform 7. The anti-collision plate 9 contacts the anti-collision plate 9, and a hydraulic airbag 8 is arranged between the anti-collision plate 9 and the lifting platform 7, which can buffer the impact force of vehicles and ships. At the same time, after the anti-collision plate 9 is hit by external force, the slider 10 connected to the anti-collision plate 9 slides toward the inside of the lifting platform 7, and the trigger rod 13 fixedly installed at the end of the slider 10 triggers the squeezing switch arranged inside the lifting platform 7. Then, when the push-type squeezing switch is turned on, the hydraulic airbag 8 will expand outward, further buffering the impact force of ships and vehicles, and avoiding damage to the lifting platform 7 and the pile body 1 connected to the lifting platform 7 caused by violent collisions of vehicles and ships. After the vehicles and ships are separated from the anti-collision plate 9, the staff can repair or replace the anti-collision plate 9 according to actual conditions. At the same time, the slider 10 can be restored to its initial position by controlling the rotation of the reset gear 14, so that the trigger rod 13 connected to the end of the slider 10 is separated from the squeezing switch, so that the entire protection component can restore the protection effect.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
