River course bridge guardrail

Abstract

The invention provides a river course bridge guardrail, particularly in the technical field of transportation facilities. The guardrail includes a base, a plurality of columns and column bodies parallel to each other, the columns are arranged on that base, the two ends of the column bodies are respectively fixed on the upright posts, the columns and the column bodies both have high structural strength, a side surface of the rail body facing the bridge is provided with a plurality of cushion portions protruding outwardly along the length direction and the cushion portions protrude from the inner side surface of the base, the cushion part comprises a cushion having a thickness of at least 10 cm, an inner cavity is arranged inside the cushion, a plurality of cushion springs are arranged in the inner cavity, and the cushion springs are arranged along the thickness direction of the cushion. The cushion part provided by that invention can cushion the impacted automobile to a certain extent,reduce the reaction force, and reduce the injury to the automobile and the personnel.

Description

technical field [0001] The invention belongs to the technical field of traffic facilities, and in particular relates to a river bridge guardrail. Background technique [0002] River 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. Most of the existing river bridge guardrails are made of reinforced concrete or stainless steel, which makes the river bridge guardrails have higher structural strength, and avoids the river bridge guardrails being broken when an accident occurs, causing the car to fall directly into the river. However, the vehicle hits When the collision occurs, it is easy to cause damage to the driver and the vehicle due to the large impact reaction force, and even threaten the life safety of the driver. [0003] Therefore be badly in need of a kind of river bridge guardrail that can solve existing problems. Contents of the invention [0004] The object of the present...
