Abstract

The invention relates to the technical field of traffic engineering, and provides a bridge guardrail prefabricating unit, a bridge guardrail construction method and a bridge. The bridge guardrail prefabricating unit comprises a guardrail wall and a pre-embedded part pre-embedded in the guardrail wall; the inner side of the guardrail wall is in an internal-sunken shape; and the pre-embedded part extends out of the bottom of the guardrail wall and is used for being mounted in a mounting hole reserved in a bridge deck in an inserted mode. Compared with a traditional cast-in-place guardrail structure, the bridge guardrail prefabricating unit can be pre-manufactured in other sites while the bridge is constructed, after the bridge deck is constructed, the bridge guardrail prefabricating unit isdirectly carried and mounted in the mounting hole reserved in the bridge deck through the pre-embedded part, the situation that the time is consumed for waiting for drying, hard and curing work of poured concrete is not needed while the dust flying situation on a construction site is reduced, and the construction period of a bridge guardrail is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of traffic engineering, in particular to a bridge guardrail prefabricated unit, a bridge guardrail construction method and a bridge. Background technique [0002] In recent years, with the rapid development of expressways in our country, the number of private car trips is increasing day by day, and the incidence of traffic accidents is getting higher and higher. The issue of traffic safety is particularly important. Therefore, when designing traffic safety facilities, it is necessary to consider more about their safety and reliability, and do a good job in protection design. At present, the common way to prevent traffic accidents is to set up guardrails on both sides of the road to form the first barrier to prevent vehicles from running out of the road. Therefore, its safety performance is directly related to the safety of drivers and passengers and the size of economic losses. [0003] Most of the existing...
