Jishuimen Bridge

Located in Hong Kong, the KAP Shui Mun bridge was once the world's longest cable-stayed bridge for both railway and train operation (this record was broken in 2000 by the channel of ERLE bridge, which spans 490 meters across Denmark and Sweden). The main span of the bridge is 430 meters, and the total length of the approach road is 820 meters. The bridge is part of route 8 Lantau link, crossing KAP Shui Mun to connect Ma Wan with Lantau Island's Tsing Chau Tsai peninsula. The speed limit is 80 km / h.

The KAP Shui Mun bridge is an important part of Hong Kong's roads because it, together with the Tsing Ma Bridge, serves as the only road link between Lantau (and Chek Lap Kok Hong Kong International Airport) and the urban area.

Architectural design

The height of the bridge is 47 meters above sea level, while the height of the tower is 150 meters. In terms of weight, the weight of concrete is 73000 cubic meters.

The construction of the KAP Shui Mun bridge started on December 21, 1992. It is a double deck design with a total contract value of HK $1643 million. The open-air upper layer of the bridge is a three lane two-way separated expressway, and the covered lower layer is the tracks of two MTR Airport Express lines and Tung Chung Line, and two single lane roads for emergency (such as typhoon).

anchored

The number of tendons varies from 51 to 102

The diameter of the steel strand is 15.7mm, which is composed of 7 galvanized steel wires

Bridge construction

The side span and the main span near the pylon are constructed on site with formwork and temporary supports.

The other main span is composed of 44 prefabricated members.

Each component weighs 500 metric tons and is 8.7 meters long. It is a composite structure of steel and concrete.

The steel part is made in Shekou, Shenzhen.

The concrete part is built on site.

The completed components are transported to the bridge by pontoon, lifted by crane and connected again.
