Connecting and constructing method of prefabricated spliced bridge pier

Abstract

The invention discloses a connecting and constructing method of a prefabricated spliced bridge pier. By increasing the length of one end of a grouting sleeve, the grouting sleeve goes deep into one side of a bridge pier section without the grouting sleeve, the grouting sleeve can penetrate through a seam, and therefore with the aid of the shearing resistance provided by a sleeve steel material, the shearing resistance of the whole seam is increased. Meanwhile, by means of the penetrating sleeve, the rigidity of the positions, near the two sides of the seam, of the bridge pier is increased, thebending resistance of the positions, near the two sides of the seam, of the bridge pier is enhanced, and the probability of rebar snapping and concrete crushing is reduced. Compared with the prior art, the method has the outstanding advantages that the damage of the bridge pier under the earthquake effect does not happen to joints any more by enhancing the bearing capacity of the joints, and themethod is better applied to the connection of the prefabricated spliced bridge pier and is particularly suitable for high-intensity areas.

Description

technical field [0001] The invention relates to a prefabricated assembled bridge pier connection structure and construction method using grouting sleeves to connect steel bars, which belongs to the technical field of prefabricated assembled structure engineering construction, and is especially suitable for high-intensity areas. Background technique [0002] Prefabricated segmental assembly construction technology has the advantages of less traffic interference, high construction quality, short construction period, low noise, and high construction safety, and has been more and more widely used in bridge construction, especially in busy cities and limited construction platforms at sea As well as the harsh natural construction, it has obvious advantages over the traditional cast-in-place construction technology. [0003] Prefabricated assembled bridge piers have been used in a large number of projects in Europe, America and other countries. The connection structure between comp...

AI Technical Summary

Problems solved by technology

Insufficient bearing capacity of the joints will directly lead to the reduction of the seismic performance of the bridge piers, making the prefabricated bridge piers with grouting sleeves connected to the steel bars not suitable for application in high-intensity areas
