Abstract

The invention provides a prefabricated anti-collision guardrail for bridge engineering. The prefabricated guardrail comprises a prefabricated guardrail body and an energy-absorbing anti-collision plate, wherein positioning sleeves are installed on the two opposite sides of the prefabricated guardrail body, the bottom of the prefabricated guardrail body is installed on a bridge floor, a plurality of positioning pieces are arranged on the bridge floor, and the positioning sleeves are arranged on the positioning pieces in a sleeving mode in a one-to-one correspondence mode; and the energy-absorbing anti-collision plate is elastically mounted on the inner side of the prefabricated guardrail body. The problems that a traditional cast-in-place concrete guardrail is complex in construction, and the bridge floor is prone to being damaged due to long-time construction on the bridge floor are solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated anti-collision barrier for bridge engineering. Background technique [0002] Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology for studying this process. It is a branch of civil engineering. The development of bridge engineering depends mainly on the needs of transportation for it. Bridge engineering includes studying aspects such as bridge maintenance. Generally, in bridge construction, the bridge deck needs to be designed with anti-collision barriers. [0003] However, at present, bridge deck guardrails are generally concrete anti-collision barriers, especially the outer concrete guardrails basically adopt cast-in-place reinforced concrete. During the construction process, it is necessary to complete the processes of binding steel b...
