Rectangular TBM application in utility tunnel

Utility tunnel is a passage built in underground to carry public utility pipelines such as electricity cables, telecommunication cables, radio and television, water supply pipes, sewer pipes, heat distribution pipeline and gas pipeline etc. Different from conventional direct burial laying method, utility tunnel is an advanced laying method. General Office of the State Council issued “Guidance on Promoting the Construction of Urban Underground Pipe Gallery” in August 2015. On the condition that the underground infrastructure construction doesn’t match with the rapid urbanization development, the Guidance clearly puts forward to promote the construction of urban underground utility tunnel and to coordinate the design, construction and maintenance of municipal pipelines to decrease disruption to traffics caused by recurrent excavation, dense overhead network and frequent pipeline accidents.

The underground utility tunnel integrates various pipelines, such as power, communication, gas, water supply, and drainage. Figure 3 shows the utility tunnel section between Jianshe Road and Youyi Road and the construction site. The construction of the utility tunnel in the city is conducive to solve problems such as frequent repair of the roads due to any faults of the installations below, which could save valuable land resources, and this important infrastructure is often called the lifeline of a city. It consists of two lines where the mainline of the utility tunnel is 13.24 km, and the branch line is 2.98 km. The mainline is covering from Youyi Road to Yangang road. The branch line is covering the part of the Wujiu railway and the Heping substation section. The monitoring centre of the comprehensive pipe gallery, fire control, drainage, electrical, ventilation, monitoring, and other ancillary works are constructed along the utility tunnel. The rainwater surface collection pipes, branch pipes, and sewage pipes are being implemented simultaneously. The utility tunnel provides the city with all kinds of necessary pipes, including pipeline conduit, high-voltage power conduit, thermal conduit, water conduit, and comprehensive conduit.

At present, China is in an important period of rapid urbanization development. By the end of 2019, the number of cities in China had increased from 132 in 1949 to 684, the urbanization rate of permanent residents had reached 60.6%, and the built-up urban area was about 60,300 square kilometers. The length of urban road and rail transit reached 459,200 km and 6,059 km, respectively (Wang 2020). Urban residents’ requirements for public infrastructure are also increasing. The State Council issued the Opinions on Strengthening Urban Infrastructure Construction in 2013, and proposed to fully launch the pilot project of utility tunnel in 36 large and medium-sized cities in about 3 years (The State Council 2013). In 2014, the central finance gave a 3-year special fund subsidy to pilot cities, and the specific amount of subsidy was determined by the scale of the city. In 2015, Ministry of Housing and Urban-Rural Development of the People’s Republic of China (MOHURD 2015a) issued “ Technical code for urban utility tunnel engineering: GB50838 – 2015” and “Notification of the printing of the guidelines for the planning of the urban underground utility tunnel” (MOHURD 2015b). In 2016, MOHURD also issued “Notification of the design system of the national building standard of the urban underground utility tunnel and the sponge city” (MOHURD 2016), these ensured the implementation of the utility tunnel from the policy level. Utility Tunnel is a structure and ancillary facility combined with the urban underground space, which can accommodate more than two types of municipal pipelines (You, He, and Wang et al. 2019). Utility Tunnel in China has been rapid development, since 2015, the annual building scale is shown in Figure 1.

A utility tunnel is a complex tunnel laid under a city road by integrating various municipal pipelines such as water supply, drainage, communications, electricity, and heat, thus achieving “unified planning and unified management of various municipal pipelines” (Figure 1) and effectively promoting the sharing and comprehensive utilization of underground space resources (Hunt, Nash, and Rogers 2014; Lbobb, Blanpain, and Buyle-Bodin 2004).
