Description

Technical Field

[0001] This utility model belongs to the field of traffic safety protection, and specifically relates to an adjustable double-layer corrugated beam guardrail structure. Background Technology

[0002] As the "blood vessel system" of modern society, the highway transportation network undertakes more than 80% of passenger and freight transport tasks. Within this vast system, corrugated beam guardrails, serving as the last line of defense for driving safety, effectively reduce impact force during vehicle collisions through their unique corrugated steel plate structure and deformation energy absorption principle, and are widely used. With my country's highway network entering a phase of "equal emphasis on construction and maintenance," asphalt concrete overlay has become a major technical means to extend road lifespan. However, for every 5cm increase in asphalt layer thickness, the effective protective height of the original guardrail decreases by approximately 3.5-4cm. Current solutions mainly adopt a "demolition-reconstruction" model, but this exposes three main problems: First, the complete dismantling rate of corrugated beam guardrails is less than 30%, with many usable components becoming unusable due to deformation; second, the reconstruction cycle is as long as 15-20 days per kilometer, during which the protection level of temporary protective facilities only reaches 60% of the original standard; third, rebuilding or replacing guardrails is costly and requires a long construction period, which may affect road traffic.

[0003] Based on the above, an adjustable double-layer corrugated beam guardrail structure is proposed. From an engineering perspective, this structure responds to the new paradigm of "facilities adapting to road surfaces"; from an economic perspective, this structure can reduce road maintenance costs and is also relatively economical in cost. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable double-layer corrugated beam guardrail structure to solve the problem of insufficient height of the corrugated beam guardrail after road overlay.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: An adjustable double-layer corrugated beam guardrail structure includes two corrugated beam plates, a three corrugated beam plate, posts, sleeves, anti-blocking blocks, buffer blocks, back crossbeams, and support pipes. The anti-blocking blocks are welded from channel steel and steel plates, and both the channel steel and steel plates of the anti-blocking blocks are provided with transverse elongated holes. The two corrugated beam plates are connected to the posts through the transverse elongated holes of the anti-blocking blocks. The top of the posts protrudes above the top of the two corrugated beam plates. The three corrugated beam plates are located vertically above the two corrugated beam plates. One side of the support pipe is bolted to the buffer block and the three corrugated beam plate, and the other side of the support pipe is bolted to the sleeves, buffer blocks, and back crossbeams. The back crossbeams are located on the back of the sleeves. The three corrugated beam plates are bolted to the buffer blocks. The top of the posts is provided with vertical elongated holes. The sleeves are connected to the top of the posts by bolts. The sleeves can move up and down along the direction of the vertical elongated holes in the posts. The posts are anchored at intervals within the road surface.

[0006] Furthermore, the buffer block can be a novel anti-blocking block or a parallelogram anti-blocking block. When the buffer block is a novel anti-blocking block, the cross-sectional shape of the novel anti-blocking block is similar to a rectangle, consisting of a front, a back, an upper, a lower and two inclined surfaces. The front and back are each provided with two transverse elongated holes for bolting to the three-wave beam plate and the sleeve, respectively. The upper and lower are each provided with a groove, and the two inclined surfaces are parallel to each other. When the buffer block is a parallelogram anti-blocking block, the cross-sectional shape of the parallelogram anti-blocking block is parallelogram-shaped, consisting of a front, a back, an upper and a lower, with the front being higher than the back in the vertical direction.

[0007] Furthermore, the cross-sectional shape of both the sleeve and the column is C-shaped or rectangular. The sleeve is provided with four rows of transverse elongated holes. The transverse elongated holes connecting the sleeve to the buffer block and the column face the impact surface of the three-wave beam plate. The transverse elongated holes connecting the column to the anti-blocking block face the length direction of the two-wave beam plates.

[0008] Furthermore, the cross-sectional shape of the back beam is a C-shaped channel steel. The back beam is composed of a first channel steel, a second channel steel, and a channel steel transition section. The inner diameter of the open end of the first channel steel is larger than the outer diameter of the second channel steel. The back beam is spliced ​​by bolting the first channel steel and the second channel steel together longitudinally. The length of the overlapping area is ≥500mm. The cross-sectional dimensions of the channel steel transition section gradually change along the length of the two corrugated beam plates.

[0009] Furthermore, the support tube has a zigzag shape when viewed from above, with an included angle of 120° to 170° between adjacent bending sections. Part of the sidewall of the support tube is cut off on both sides to form cuts, and the inner contour of the support tube is attached to and bolted to the outer contour of the first channel steel of the back crossbeam.

[0010] Furthermore, the column can be anchored to the road surface by piling, burying, flange, or pre-embedded sleeve. When the column is vertically anchored to the road surface by piling, the depth below the road surface is not less than 1m.

[0011] Furthermore, the anti-blocking block, buffer block, back crossbeam, and support tube are integrally pressed or welded using a mold.

[0012] Furthermore, the materials of the two-wave beam plate, three-wave beam plate, column, sleeve, anti-blocking block, buffer block, back crossbeam and support pipe are ordinary carbon steel, weathering steel, or alloy steel, or a combination thereof.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects: (1) It has pre-maintenance and renovation and upgrading functions, which is beneficial to later maintenance; (2) It has a high safety reserve, meets the protection level requirements, and better maintains the safety of highway operation.
