[0002] Highway traffic safety is a hot topic of concern in all countries. Guardrails, as basic safety facilities on highways, play an important role in the passive safety of highway driving. It is crucial to install safe and reliable guardrails. Corrugated beam guardrails are a common form of guardrails on my country's highways. They are divided into central median guardrails and roadside guardrails according to their installation location. At present, central median corrugated beam guardrails are generally set in double rows, that is, two columns and two rows of corrugated beam plates. The backs of the two columns need to have a certain distance, so they occupy a certain width in the middle of the road. During the construction and renovation and expansion of highways and national and provincial trunk roads, more diverse requirements are put forward for central median guardrails, including reliable protection performance, small footprint, beautification of the traffic environment and economical cost. However, the existing central median guardrail results are still incomplete.

[0003] Based on the above situation, a narrow central median corrugated beam guardrail structure is proposed. This structure can effectively protect vehicles involved in accidents while reducing floor space. This structure is easy to construct and install, and can better maintain the safety of highway operations. Utility Model Content

The corrugated beam plates on both sides are connected to the columns through two anti-obstruction blocks. The columns are anchored in the central dividing strip foundation at intervals. The anti-obstruction block is integrally pressed by a mold and is open in four directions: upper, lower, front and rear. The anti-obstruction block consists of a web, a top plate and side plates. The web of the anti-obstruction block is special-shaped. The two ends of the web of the anti-obstruction block are fitted with the corrugated beam plates on both sides. The side plates are vertically arranged on both sides of the web, and the web is bolted to the columns. The side plates of the anti-obstruction block are bolted to the corrugated beam plates on both sides. The top plate of the anti-obstruction block is provided with rounded corners.

[0007] Furthermore, an oblong hole is provided in the vertical direction of the web of the anti-blocking block, and a circular hole is also provided on the column. After the column and the web of the anti-blocking blocks on both sides are fitted and corresponded, bolts are inserted to form a connection.

[0008] Furthermore, oblong holes are provided on the side plates of the anti-blocking block, and oblong holes are also provided on the corrugated beam plates. After the corrugated beam plates and the side plates are fitted and aligned, bolts are inserted to form a connection.

[0009] Furthermore, the cross-sectional shape of the column is a hollow cylinder or a rectangular square column, and the column can be anchored to the road surface by piling, burying piles, or flanges.
