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 taken for different types of pier column structures, for a rectangular pier, an isolated flexible anti-collision system is arranged for protection by adopting a complete isolation concept; for a cylindrical pier, an adhesive flexible anti-collision system is adopted; for a large-scale pier which cannot be equipped with a flexible anti-collision facility due to the space constraint, a reinforced guardrail anti-collision system is adopted; and for a pier column group which is dense and each pier column cannot be protected individually, a middle pier prefabricated and assembled integral wall-type anti-collision island is adopted. The four anti-collision systems are designed according to the characteristics of pier columns. The anti-collision structure is small in size, strong in anti-collision ability, convenient to assemble and disassemble, and can basically achieve the purpose of protecting the middle piers of expressway overpasses. The invention relates to four anti-collision system structures and also relates to the relevant construction methods, and has good economic and technical benefits.

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...
