Survey questionnaire results of the current level of knowledge on trenchless technologies in China
چکیده انگلیسی

With a growing population and densely populated urban environments, China is looking at alternative methods of underground pipeline installation and replacement of their aging infrastructure. Conventional open trench activities result in disruption to these urban centers through road closures, traffic delays, traffic detours, loss of access to homes and business, unsightliness, noise and general disruption for everyone. Trenchless technologies are a viable and sustainable solution to China’s buried infrastructure. Numerous challenges are present when promoting trenchless technologies in China including minimal local engineering knowledge, lack of trained contractors, lack of specifications, and system impact concerns raised by government owners. This paper presents the results of a survey questions obtained from a cross-section of 209 Chinese engineers from Shanghai, Beijing, Shengyang, Chongqing, and Guangzhou to gain a snapshot of the current level of knowledge on trenchless construction methods. The results reveal an understanding of trenchless technology in general; however, a lack of understanding of technologies such as lining of pipe, trenchless grouting, auger boring, and pipe bursting. Pipe jacking and horizontal directional drilling are currently by far the most recognized and understood trenchless technologies in China.
