Stable inclined pier construction method without interrupting traffic operation

Abstract

According to the construction method for stabilizing the inclined bridge pier without interrupting traffic operation, the inclined bridge pier is limited by arranging the stabilizing cable anchor, the winch anchor, the horizontal stabilizing cable and the pier body stabilizing cable, the steel pipe lattice pier is constructed around the inclined bridge pier, loads on the upper portion of the inclined bridge pier are arranged on the steel pipe lattice pier, and therefore the inclined bridge pier is stabilized. And then newly building a bridge pier column, and finally removing the steel pipe lattice pier to finish the whole construction process. According to the method for repairing the inclined bridge pier, the social influence is small, normal traffic can be rapidly recovered under the condition that the quality and quantity are guaranteed to repair the bridge, inconvenience caused by traffic interruption is avoided, the social influence is reduced as much as possible, the social benefit is greatly improved, and the good economic benefit is obtained; particularly, the'pier stabilizing mode 'in the construction process is the first case of the whole country, and the blank of the bridge reinforcing technology is filled.

Description

technical field [0001] The invention relates to the technical field of bridge and road repair, in particular to a construction method for stable inclined bridge piers that does not interrupt traffic operation. Background technique [0002] With the rapid development of bridge construction in my country, bridge diseases frequently appear in the process of bridge construction and use, and the treatment of bridge diseases is becoming more and more prominent. The displacement, fracture and damage of the pile foundation lead to the large inclination of the lower part and the upper structure of the bridge, which makes the bridge have major safety hazards and seriously affects the safe use of the bridge. Safe use status. [0003] Since the bearing capacity of the diseased pile foundation cannot be determined, and the piers are still in slow displacement, the system may be close to a critical equilibrium state. Under the action of small external forces, bridge collapse and casualties...

AI Technical Summary

Problems solved by technology

[0002] With the rapid development of bridge construction in our country, bridge diseases frequently appear in the process of bridge construction and use, and the treatment of bridge diseases has become increasingly prominent, such as bridges caused by uneven earthwork loading, water pressure, earthquakes or other reasons. The displacement, fracture, and damage of the pile foundation lead to a large inclination of the lower and upper structures of the bridge, which poses a major safety hazard and seriously affects the safe use of the bridge. The bridge needs to be dealt with before it can be restored to normal safe use status

[0003] Since the bearing capacity of the damaged pile foundation cannot be determined, and the pier column is still in slow displacement, the system may be close to the critical equilibrium state. Under the action of a small external force, bridge collapse and casualties may occur during the risk removal construction process, which is extremely risky , so the traditional disposal methods such as "blasting" and "top-down demolition" are no longer applicable, and if the above-mentioned methods are used for processing, the main body of the bridge road will be greatly damaged, and it will not be open to traffic for a long period of time after the repair Operation, social impact and impact on economic benefits are relatively large
