Abstract

The invention discloses an assembly type highway tunnel crash barrier which comprises a base pedestal and a buffer mechanism arranged on the base pedestal, the base pedestal comprises a left side walland a right side wall, a groove is formed in the left side wall, and a convex strip matched with the groove is arranged on the right side wall; the buffer mechanism comprises a fixing block located on the side wall of the base pedestal, supporting rod assemblies are symmetrically arranged on the fixing block, each supporting rod assembly comprises a first supporting rod and a second supporting rod which are arranged in an open mode, and an elastic pull rope is connected between each first supporting rod and the corresponding second supporting rod and the elastic pull rope, the first supporting rod and the corresponding second supporting rod are arranged in a triangular mode. A dismounting assembly is arranged between the fixing block and the base pedestal, and auxiliary buffer assembliesare arranged between the first supporting rod and the side wall of the base pedestal and between the second supporting rod and the side wall of the base pedestal; the problem that an existing guardrail cannot play a certain role in buffering a vehicle can be solved.

Description

technical field [0001] The invention relates to the technical field of highway guardrails, more specifically, it relates to a prefabricated road tunnel anti-collision guardrail. Background technique [0002] The guardrail refers to the guardrail set on the road to protect personal safety and equipment and facilities. Its purpose is to prevent out-of-control vehicles from getting out of the bridge, and has the function of preventing vehicles from breaking through, underpassing, and overturning the road and beautifying the road. According to the structural features, it can be divided into beam-column (metal and concrete) guardrails, reinforced concrete wall-type expanded guardrails and combined guardrails. The existing concrete wall bridge guardrail, which includes an upper retaining wall part and a lower base unit part with a slope, is a rigid anti-collision guardrail structure, and guides the vehicle to collide and climb by preventing out-of-control vehicles from rushing out...
