Description

Technical Field

[0001] The utility model relates to the technical field of bridge guardrails, and in particular to a lightweight assembled concrete bridge guardrail structure. Background Art

[0002] With the rapid growth of my country's economy and the vigorous development of road transportation, the traffic volume has increased rapidly, especially the increase in large and heavy-loaded vehicles, which has directly led to an increase in the frequency of use and load of road traffic facilities. People are paying more and more attention to the safety of transportation. Highway guardrails play a vital role as the last line of defense for traffic safety.

[0003] However, the construction process of cast-in-place is more complicated, the construction period is long, the site occupies a large space, it is not convenient to use on sections of road that need to be "open", and there is a certain degree of difficulty in later maintenance and repair. In addition, the concrete structure is crushed when dismantled and cannot be reused, resulting in a huge waste of resources. Precast concrete guardrails are usually bulky in structure, and equipment must be used on site for lifting and positioning, which brings problems to the bearing capacity of the bridge. The anchors are manually connected, and the positioning and connection are difficult. The line shape is not easy to adjust. The construction process is also dangerous for on-site workers.
