Introduction of Luzhou Huangpi Yangtze River Bridge?

Luzhou Huangpi Yangtze River Bridge, located in Huangpi Town, Luzhou City, Sichuan Province, is a super-large bridge across the Yangtze River at Luchi Expressway (Luzhou section). Construction started on 20 10 1 with a total construction period of 36 months.

Building structure

The main bridge of Huangpi Yangtze River Bridge is a continuous beam semi-floating cable-stayed bridge with a span of 10. The concrete layout of the high and low twin towers and their spans is (39+53+48)+520+(53+5×48)m, and the main span is larger, reaching 520m, and the conversion span is 696m according to the tall tower.

The lower part of the approach bridge is a cylindrical pier, and the upper part is a prefabricated T-beam, with 9 spans of * * * and a span of 3×(3×30)m, and a continuous system is formed every 3 spans, each span is 10 T beam, and the whole bridge is 90 T beam. There are three main features of this bridge: first, the shape of the high and low twin towers; Second, the main beam is a mixed beam structure; Third, the cables are arranged asymmetrically. The height of the high tower of the main bridge is 2 10m, and the height of the low tower is123.5m. The height difference between the two towers is quite large, reaching 86.5m The box girder of the main bridge is of mixed beam structure, the side span is concrete box girder, and the middle span is steel box girder. The parting line of the steel-concrete joint section is set at 12m from the mid-span of the cable tower cross bridge to the vicinity of the central axis. Due to the structural differences between the side span and the middle span, the loads on both sides of the tower are unbalanced, so the stay cables on both sides of each main tower are arranged asymmetrically.

The significance of bridge construction

Huangpi Yangtze River Bridge is an important channel for Sichuan to go out to sea. The construction of the bridge is conducive to enhancing Chengdu's economic radiation capacity, and is of great significance to realizing land-water combined transport, building a comprehensive transportation hub in the west and promoting coordinated economic and social development along the line.

work progress

20 12 The main bridge of Huangpi Yangtze River Bridge was successfully closed.

April 20 14, the main project of Huangpi Yangtze River Bridge has been completed, and the construction unit is doing the finishing work.

In May of 20 14, the Huangpi Yangtze River Bridge successfully passed the load test a few days ago, which indicates that the Huangpi Yangtze River Bridge has been put into use, which will further ensure the smooth opening of the Luchi section from Chengzi to Luchi expressway in June of 20 14.

On June 20 14, the Luchi section from Chengzi to Luchi expressway was officially opened to traffic, which also marked the official opening of Huangpi Yangtze River Bridge.
