National Road 205 Shenzhen section retrofitting project

The reinforcement of the main bridge across the construction site: foundation reinforcement, pier reinforcement, beam reinforcement, bearing replacement, rework of deck pavement, expansion joints, taiwan slab.

Project overview

The construction of the highway retrofitting project of 205 G5106 Shenzhen section, the pile No. K26+900 ~ K37+351.428. The design starting point K26+900 is located in Longgang Street office, the end K37+351.428 is located at the border of Shenzhen and Huizhou, and the line is full of 10.449km. This section consists of the main line of 6 bridges, Long Park Road Bridge, Longgang bridge, West Lake Tang Bridge, Ding Shanhe bridge, Tun Zi River Bridge and pond bridge, in which the design of the small rivers and the Longgang River Bridge Bridge Bridge II for the demolition and reconstruction, the other is the bridge design for reinforcement. The bridge reinforcement are shown in the following table:
