Length：691m

Application：Concrete rainwater pipes

Project Introduction：The pipe was a DN1300 concrete pipe with a burial depth of 4 meters. The construction area had a large volume of vehicle traffic and drainage throughout the year，affected by the long-term external environment, the pipe had suffered multiple problems such as uneven settlement, damage, and corrosion. The overall requirements of the project included reducing the impact of construction on traffic flow, shortening the overall construction period, reducing noise pollution, and controlling environmental pollution, among other practical considerations.

Construction Challenge：

1. It needed to meet the requirement of E-Module：20500 MPa.

2. The location had a high volume of vehicles and traffic, requiring a short overall construction period to reduce pollution to the surrounding environment during construction.
