Project Site @ Dujia Village, Xinglong Town, Yubei District, Chongqing, China

  • Project Background
  • Work Progress




Located in a hilly area at Xinglong Town in Chongqing, Dujia Village suffers economically as people move out.

A river cuts through an important pathway 50 meters from the Dujia primary school, and villagers can only wade across it. As water rises to up to two meters deep every year from May to September, crossing becomes highly dangerous.

As the water is deep and rapid during summer every year, it is recommended to build a bridge with deck height above a flood level to prevent flooding of wood and stones which may damage the bridge.

Apr 2018 - project progress

In mid-March, the team cleared the construction site of the river, installed railings, completed bamboo flooring work for the bridge deck and lighting system. The bridge completion ceremony was held in the morning on April 8.

This "Yi Xin Qiao" is the longest bamboo bridge in the rural mainland. The bridge, measuring 21 metres long, marks a breakthrough in modern bamboo bridge building. 


Mar 2018 - project progress

Since March 2017, the team had conducted investigations and surveys five times in Dujia Village. Meanwhile, mechanical experiments were conducted at Tsinghua University. In September, the construction of bamboo bridge foundations was completed. Afterwards, the bamboo materials were made with anti-corrosion and bug resistant treatment. Finally, concrete paving of the bamboo bridge deck was completed and the main construction work of the bridge was completed on 5 February 2018.

In addition, the bridge design scheme won the first prize in University Student Bridge Design Competition in Beijing National Convention Center in June 2017.


Feb 2018 - project progress

During the period from January 28th to February 4th, CUHK -Tsinghua University joint workshop on modern bamboo and wood structure was held on bridge site. The students from School of Civil Engineering at Tsinghua University came to the village to learn the characteristics of bamboo and its design and construction techniques of the bamboo structure. They also did some handicraft work with the students from Xinglong Primary School. With the help of the construction team, the students designed and built a “Yujing Pavilion” for the villagers. Through this workshop, they learned the design and construction knowledge of bamboo structures in practice, increased their passion for bamboo culture, and began to pay attention to the situation of rural areas in China.


Mar 2017 - project progress

The team conducted an investigation trip in Mar. Mapping and data collection work were done. As there are more mud on both river sides, it is appropriate to have a larger span for the bridge. Initial proposed bamboo arch bridge can be 20 meters long. Please click here to see the work report (in Chinese version only).

Jan 2017 - project progress
