Prefabricated lightweight high-strength bridge crash barrier

Abstract

The invention discloses a prefabricated lightweight high-strength bridge crash barrier applied to the technical field of bridges. The prefabricated lightweight high-strength bridge crash barrier comprises a barrier precast by ultra-high performance concrete (UHPC), wherein the barrier is arranged on the bridge by virtue of an embedded part arranged on the bridge; the barrier comprises a side panel, a bottom plate and ribbed plates arranged on the outer side of the side panel; a mounting position matched with the embedded part is arranged on the bottom plate. The crash barrier disclosed by theinvention is divided into the panel and the ribbed plates, so that the weight of the crash barrier is effectively reduced. Meanwhile, due to super-toughness of the UHPC, after an automobile collides with the UHPC crash barrier, the barrier does not cause brittle failure, and the automobile is prevented from dropping from the bridge. Moreover, the UHPC crash barrier can realize industrialized production and field prefabricated construction, and the environmental pollution is greatly alleviated.

Description

technical field [0001] The invention is used in the technical field of bridges, and in particular relates to a prefabricated light-weight high-strength bridge anti-collision guardrail. Background technique [0002] The anti-collision guardrail is an important part of the bridge. The traditional reinforced concrete retaining wall is cast on site, which is heavy and increases the construction period. Contents of the invention [0003] The purpose of the present invention is to provide a prefabricated light-duty high-strength bridge anti-collision barrier, which divides the anti-collision barrier into panels and ribs, effectively reducing the weight of the anti-collision barrier, and at the same time due to the super toughness of the UHPC material, it is easy for cars to collide The rear guardrail of UHPC anti-collision barriers will not undergo brittle failure, preventing cars from falling off bridges, and UHPC anti-collision barriers can realize industrial production and on...

AI Technical Summary

Problems solved by technology

[0002] The anti-collision guardrail is an important part of the bridge. The traditional reinforced concrete retaining wall is cast on site, which is heavy and increases the construction period. The degree of assembly is low and the construction pollution is increased. It does not meet the national requirements for the development of green buildings.
