Middle pier anti-collision system and construction method

Abstract

The invention relates to a middle pier anti-collision system and a construction method. Different anti-collision measures are respectively adopted for different types of pier column structures. For rectangular piers, an isolation type flexible anti-collision system is arranged by adopting a complete isolation concept for protection; for the cylindrical pier, an attached flexible anti-collision system is adopted; when a flexible anti-collision facility cannot be arranged on a large-size pier due to space limitation, a reinforced guardrail anti-collision system is adopted; when pier column groups are dense and anti-collision protection measures cannot be taken on each pier column independently, a middle pier prefabricated assembly integral wall type anti-collision island is adopted. The fouranti-collision systems are designed to be of different structures according to the characteristics of pier columns, the anti-collision structure is small in size, high in anti-collision capacity andconvenient to assemble and disassemble, and the purpose of protecting piers in the expressway overpass can be basically achieved. The invention further relates to a related construction method while relating to the four anti-collision system structures, and good economic and technical benefits are achieved.

Description

technical field [0001] The invention relates to the field of anti-collision of middle piers, in particular to an anti-collision system of middle piers and a construction method, which is applicable to the anti-collision systems of piers of various structural forms in expressways. Background technique [0002] There are many overpasses on the expressway in various forms, mainly including girder bridges, arch bridges and oblique-leg rigid frames. Most of the girder bridges are equipped with piers in the central divider, but no anti-collision measures are taken. [0003] In recent years, with the rapid growth of car ownership, my country's road traffic safety is not optimistic. Traffic safety accidents caused by cars hitting bridge piers occur frequently. and property damage. Therefore, it is imperative to add anti-collision measures to bridge piers. [0004] In view of this, in order to reduce the impact of vehicles on the pier and improve safety, it is urgent to invent a sim...
