Prefabricated assembling bridge pier connecting device and construction method thereof

Abstract

The invention relates to a prefabricated assembling bridge pier connecting device and a construction method thereof. The prefabricated assembling bridge pier connecting device comprises a pier bottomconnecting device at the bottom of a prefabricated bridge pier and a pile-cap connecting pre-embedded device on the top of a cast-in-place pier cap; and connecting and fixing of the prefabricated bridge pier and the cast-in-place pier cap are achieved through up-down matching and installing of the pier bottom connecting device and the pile-cap connecting pre-embedded device. According to the prefabricated assembling bridge pier connecting device and the construction method thereof, the prefabricated assembling bridge pier with a connecting form of steel plate wrapping and U-shaped ribs and fine-rolling screw-thread steel is adopted, the construction process is simple and convenient; compared with other forms, the site construction process is less, the construction efficiency is greatly improved, and construction quality is ensured most effectively; safety and reliability are high, and the prefabricated assembling bridge pier connecting device and the construction method thereof can beapplied to areas with high seismic intensity; and the connecting structure has a certain anti-collision protection function to a bridge pier main body so that the prefabricated assembling bridge pierconnecting device and the construction method thereof can be widely popularized in city bridges.

Description

technical field [0001] The invention relates to the technical field of bridge engineering design and construction, in particular to a prefabricated assembled pier connection device and a construction method thereof. Background technique [0002] With the rapid development of traffic, especially the rapid development of municipal engineering, higher and higher requirements are put forward for construction efficiency, construction speed and reducing the impact of construction on existing lines. As a form of pier construction, prefabricated piers can greatly improve the efficiency of pier construction and minimize the impact of substructure construction on traffic. More and more prefabricated assembled bridge piers have been applied in engineering and have been widely recognized. This technology is still developing and improving, and the segmental connection device is one of its core technologies. [0003] The existing prefabricated and assembled pier forms and connection devi...

AI Technical Summary

Problems solved by technology

[0003] The existing prefabricated and assembled pier forms and connection devices have the following disadvantages: 1. The construction technology of the connection device is relatively complicated; Waste; 3. The connecting device adopts the type of precision-rolled rebar, which has many joints and complex forms, and the connection between segments is realized only by the bonding strength between materials, and the reliability is relatively weak; 4. Other forms , the on-site construction project has a large amount and complicated process; 5. The connecting device has no other auxiliary functions for the safety of the bridge structure
