Urban bridge guardrail capable of preventing vehicle from falling off river

Abstract

The invention belongs to the technical field of urban bridge guardrails, particularly relates to an urban bridge guardrail capable of preventing a vehicle from falling off a river, and aims to solve the problems that on the basis of the technical conditions of existing bridge guardrails, many defects still exist in the use range and convenience of the guardrails, most of the bridge guardrails are single in function and only single in protection effect, and the service life of the guardrails is affected. In order to solve the problems that existing guardrails are high in rigidity and lack of a certain buffering effect, most of the existing guardrails are integrated and are inconvenient to mount and replace after being collided and damaged, the following scheme is provided: the guardrail comprises a mounting plate and a mounting head, a transverse plate is fixedly mounted at the bottom of the mounting plate, and a plurality of threaded holes are formed in the transverse plate; locking devices are movably installed in the multiple threaded holes. The guardrail can be combined to be used, replacement and maintenance are convenient when the guardrail is damaged, a certain buffering effect is achieved when the guardrail is collided, meanwhile, the warning and reminding device is arranged, and the occurrence frequency of collision accidents is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of urban bridge guardrails, in particular to an urban bridge guardrail for preventing vehicles from falling into rivers. Background technique [0002] Bridge guardrail refers to the guardrail set on the bridge. Its purpose is to prevent out-of-control vehicles from getting out of the bridge. Highway grade, comprehensive consideration of its safety, coordination, characteristics of objects to be protected and on-site geometric conditions to determine the anti-collision grade, and then select the structural form according to its own structure, economy, construction and maintenance and other factors, the other Embedding methods include column direct embedment, flange connection, and bridge guardrail and bridge deck pouring into one through force-transmitting steel bars. When conditions permit, removable guardrails can be used to classify bridge guardrail types. Many, in addition to the division according to th...

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical conditions of the existing bridge guardrails, but there are still many deficiencies in the scope and convenience of the guardrails. Most of the bridge guardrails have single functions and can only achieve a single protective effect. At the same time, the hardness is relatively strong, lacks a certain buffering effect, and most of the existing guardrails are integrated, which is inconvenient to install and replace after collision damage. A guardrail for urban bridges that prevents vehicles from falling into rivers is proposed.
