As a cutting -edge city for the development and utilization of urban underground space across the country, Hangzhou has reached a reality in overall planning and standardizing the development and construction of underground space.

Recently, the Hangzhou Municipal Construction Commission released the country's first underground public connection space design guide- "Hangzhou key area underground public public connection space design guidance (trial)" (referred to as the guidance).

This is the guidance manual written by the expert team after investigating and investigating underground public connection spaces in various places. It will coordinate and standardize the design, construction and management of underground public connection space in the key areas of Hangzhou, and provide guidance for underground public connection space layout and design.

What is an underground public connection space? Simply put, the underground pedestrian channels we walk on the road, commercial streets connected to subway malls, and sinking squares are all underground public connection space.

"With the rapid development of Hangzhou urban construction, the contradiction between supply and demand of land resources is increasingly prominent, and the needs of developing underground space and improving the degree of intensive land use is increasingly urgent." Chen Yanping, the relevant staff of the Hangzhou Construction Committee of the Hangzhou Municipal Construction Committee, " The standards for issuance mainly regulate the terms, functions and facilities, and planning requirements of urban underground spaces. There are no contents that are specifically connected to the underground space in the overall area of ​​the city. "

The release and implementation of the "Guidelines" has filled the gap in this area, which is important to strengthen the interaction of underground space, enhance the quality and safety of the underground public space, and promote the underground space of Hangzhou's urban underground space from "quantitative change" to "qualitative change" and other important. Guiding significance.

With this "Guideline", the new underground public connection space in the future will be more humane.

For example, in the future, underground transportation facilities will be connected as much as possible with adjacent underground commercial service facilities as much as possible; when the length of the underground commercial street exceeds 100 meters, it is necessary to broaden the pedestrian channels and increase the facilities such as entrances and exits; underground public channels will also be more spacious, width, width, width, and width It is not less than 5 meters and the net height is not less than 3 meters. If there are commercial facilities on both sides, the net width will not be less than 6 meters.

In addition, the underground passage will also change the dark feeling in the past and become brighter and beautiful. The "Guidelines" pointed out that the internal environment of the underground connection channel should be bright and follow the principles of security, beauty, economy, and practicality.

It is worth mentioning that the "Guidelines" guide the overall layout of underground public connection spaces in different types of key areas to improve the quality and safety of the construction of underground space.

"Underground space interconnection is a very good direction, but if there is no unified standard and coordinating plan, each of them will also bring risks." Wu Zhou, a member of the party committee member of the Hangzhou Metro Commercial Management Company, told reporters that in the "Guidelines Under the guidance of the unified planning, coupled with the tacit cooperation between the management entities, the coordination of the various functions of the transportation facilities, commercial facilities, pipe corridors, civil air defense, flood control and other functions of the underground space will inevitably improve the underground space of Hangzhou underground space Utilization and quality.

It is understood that the "Guidelines" documents have been issued in Hangzhou and sent to various planning and design units and approval departments to check the high -quality development of underground space.
