Description

Prefabricated underground pipe gallery

technical field

The invention belongs to the technical field of buildings and relates to an assembled underground pipe gallery.

Background technique

The underground pipe corridor, also known as the common ditch, is a municipal public facility that implements unified planning, design, construction and maintenance, and is built underground in the city for laying municipal public pipelines. Refers to the public tunnels that are used to centrally lay municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas underground in cities.

As early as the 1920s, the municipal government of Tokyo, the capital of Japan, laid power, telephone, water and gas pipelines under the main roads in the Kudan area of the city center, forming the first underground comprehensive utility corridor in Tokyo. Since then, the "Law on Special Measures Concerning the Construction of Common Ditches" enacted in 1963 has stipulated from the legal level that relevant Japanese departments need to build "common ditches" underground on major arterial roads with heavy traffic volume and potential congestion in the future. The Tokyo National Highway Office under the Ministry of Land, Infrastructure, Transport and Tourism is responsible for the construction and management of the underground comprehensive utility corridor of the main line in the Tokyo area, while the underground comprehensive utility corridor of the secondary trunk line is in charge of the Tokyo Metropolitan Construction Bureau.

As early as 1958, Beijing had laid a comprehensive pipe corridor of more than 1,000 meters under Tiananmen Square. In 2006, the second modern comprehensive utility corridor in mainland my country was built in the west area of Zhongguancun. The main line of the comprehensive pipe gallery is 2 kilometers long, and the branch line is 1 kilometer long, including municipal pipelines such as water, electricity, cold, heat, gas, and communications. In 1994, the Shanghai Municipal Government planned and built the first comprehensive utility corridor with the largest scale and the longest distance in the mainland—the comprehensive utility corridor on Zhangyang Road, Pudong New Area. The comprehensive utility corridor has a total length of 11.125 kilometers and accommodates four urban pipelines including water supply, electricity, information and gas. Shanghai has also completed the first phase of the Songjiang New Town Demonstration Underground Comprehensive Pipe Gallery Project and the comprehensive pipe gallery system in Anting New Town, Jiading District, with a total length of about 6 kilometers. The infrastructure construction of Suzhou Industrial Park jointly developed by China and Singapore, after 10 years of development, the underground pipeline corridor has also begun to take shape.

The State Council attaches great importance to promoting the construction of urban underground comprehensive pipeline corridors. Since 2013, it has successively issued the "Opinions of the State Council on Strengthening Urban Infrastructure Construction" and "Guiding Opinions of the General Office of the State Council on Strengthening the Construction and Management of Urban Underground Pipelines" to deploy and carry out urban underground comprehensive Pipe gallery construction pilot work.
