Chapter Project Description

1.1, Project Description
The project name is cis to Beijiao Foshan Highway Route DS-14 main sections, the Stake for the k24 +850--k28 +180, total length 3.33km, was roughly north-south, along the plains of this project, there are between residual hills, the area across the road, waterway more. Number of major projects including: earthwork embankment at about 1.39 million cubic meters, 25,333 meters of Sand Wick, culvert 3, a total of 292 cross-running meters, 11,928 meters pipeline project. Bridge a road bridge to cross the South Salt length 590 meters, the main bridge is 30 +45 +30 m continuous prestressed box girder, single box three rooms, 2.3 meters high beams, approach bridge is 20 meters in the first and Prestressed Concrete hollow beam, the number of prestressed hollow plate beam design for the 828. Auto Channel 1, a pedestrian bridge. Full-bridge are bored pile foundation, pile into the weak wind of not less than two meters, which Ф800mm total 348 m, Ф1200mm total of 1427 meters, Ф1600mm total of 3675 meters. Key and difficult project as a road bridge across the South of salt.
