The Shenzhen government is launching a large-scale urban project to utilize the underground space in the Qianhai area. The space will be used for underground transport networks, commercial use and public facilities, the Shenzhen Economic Daily reported yesterday.
Occupying an area of 15 square kilometers, Qianhai is planned to accommodate 150,000 residents and it will employ above 650,000 people in the future. It pushed policymakers to realize the value of the underground space.
According to the government plan, there will be 6.3 million square meters of underground space available for development in Qianhai, and an area as large as 4 million square meters will be built into underground parking space.
The underground public passages and commercial areas will be 1.3 million square meters, while public facilities will occupy an area of 1 million square meters.
Guo Jun, director of the construction department of Qianhai Authority, said there will be 12 Metro lines and 37 stations in Qianhai area as the rail transit network is essential for Qianhai's transportation system, which will be able to meet the travel demand of 250,000 to 350,000 passengers during rush hour in the future.
Underground roads with an overall length of 5.5 kilometers will be built in Qianhai, which will be connected to underground areas.
Guo said the underground roadway system will effectively relieve the traffic pressure on the ground.
A 24.3-kilometer underground pedestrian network will be constructed to link with underground commercial areas in Qianhai.
Thirteen garbage transfer stations, 11 power transformer substations, 10 refrigeration stations and 39 public bus stations will be built underground. A utility tunnel of 9.2 kilometers will be built to facilitate the construction of water pipelines and power cables.
