Description

Technical Field

[0001] The utility model relates to the technical field of expressway engineering, in particular to a reinforcement pile for expressway construction. Background Art

[0002] Expressways are high-grade roads that adapt to the development of industrialization and urbanization. Cities are the gathering places of industries and population. The growth of cars in cities is much faster than that in rural areas, and they become the gathering centers of cars. Therefore, the construction of expressways often starts from the city's ring roads, radial roads and busy traffic sections, and gradually becomes an urban transportation with expressways as the backbone. During the construction of expressways, reinforcement piles will be set at forks and repair places. The reinforcement piles are distributed along the route to indicate the driving direction of vehicles and prevent vehicles from running off the road, so as to protect vehicles and passengers and reduce accidents.

[0068] Connecting rods 315, multiple groups of connecting rods 315 are distributed on both sides of the supporting plate 311;

[0069] The connecting rod 315 is curved along the trajectory of the arc-shaped slide groove 312;

[0070] A plurality of connecting rods 315 are movably inserted into the sliders 314 at corresponding positions;

[0077] A second spring 318 is sleeved on the slide bar 313 located between the two sets of arc-shaped slide grooves 312 .

[0078] Specifically, when the vehicle collides with the reinforcement pile, it passes through the buffer part 33, the buffer part 2 32 in sequence, and then passes through the buffer part 1 31 for buffering, wherein the support plates 311 of the buffer part 1 31 are spaced apart on the mounting plate 21, and the support plates 311 are in an arc-shaped structure. Similarly, the buffer part 2 32 and the buffer part 1 31 are also in an arc-shaped structure. When the vehicle collides with the reinforcement pile, the buffer mechanism 3 with an overall arc-shaped structure can produce a good buffering effect. A plurality of groups of arc-shaped grooves 312 are provided on the support plate 311, and a slide bar 313 is inserted into the arc-shaped groove 312. The slide bar 313 can slide in the arc-shaped groove 312. Both ends of the slide bar 313 extend to the outside of the arc-shaped groove 312 and are connected to a slider 314.

The first spring 317 is between the slider 314 and the fixed plate 316. When the sliding bar 313 is pushed to move inward, the slider 314 slides on the connecting rod 315 toward the fixed plate 316. When the slider 314 slides toward the fixed plate 316, it gradually squeezes the first spring 317. The first spring 317 is compressed to form an elastic buffer. When the vehicle collides and squeezes the sliding bar 313, the first spring 317 is in a compressed state, thereby buffering the vehicle.

[0079] The second spring 318 is sleeved on the slide bar 313. When subjected to pressure from the left and right sides, the second spring 318 can provide elastic tension or compression force, thereby buffering the vehicle in the left and right directions.

[0084] The buffer third part 33 is covered on the outside of the cover plate 321;

[0085] The outer surface of the third buffer part 33 forms a plurality of groups of concave-convex grids.

[0086] Specifically, when the vehicle collides with the reinforced pile, it first contacts the buffer part 33. The outer surface of the buffer part 33 is in a bumpy grid shape, which can generate friction and then perform the first step of buffering for the vehicle. After that, the buffer part 32 performs the second step of buffering. The buffer part 32 has a multi-layer structure. The shock-absorbing pad 322 and the pressure-resistant layer 324 can be made of elastic rubber material. A plurality of groups of third springs 325 are arranged in the buffer cavity 323. When the third spring 325 is compressed, an elastic buffer is formed, which can effectively alleviate the collision intensity of the vehicle.

[0087] Baffles 4 are installed at the openings between the two sides of the buffer third part 33 and the mounting plate 21 .

[0088] Specifically, the buffer mechanism 3 is an arc-shaped structure from the inside to the outside, and baffles 4 are installed at the openings on both sides for blocking.
