Chengdu, Sichuan

15. Construction on One Circle Road

Before the bike lane goes in a ditch was dug for pipes. Drainage pipes were put in and natural gas pipes were to be laid in the ditch. The ditch was 20 feet deep and dug by hand. The soil was carried out by men using rice straw baskets carried on yokes. Then the men are lower one of the pipes down to the bottom of the ditch by hand. In this area of China has an abundance of natural gas. We use it for heating and cooking. During lunch time the gas pressure goes down to almost nothing and at night there is excessive pressure. There were no pressure regulators in 1984. By 1994 they had begun to be available.
