Abstract:
The pipe pulling construction of large-diameter pipeline belongs to a high risk operation, and the construction difficulty increases further in complex geological conditions, pipe pulling construction is of great difficulty and has a high accident rate. According to the case analysis for the failure in pipe pulling construction of large-diameter long-distance pipeline in rock area, this paper presents the technical problems of pipe pulling existed in design, construction and management. It is considered that the performances of pulling equipments at home and abroad should be confirmed, geological investigation be strengthened, construction risks be avoided with sound prevention measures at any time, and finally the design scheme for pipe pulling be optimized, which mainly includes eliminating the possible influences from the shaft construction and pipe pulling construction, perfecting the design scheme based on field construction conditions, enhancing the management of the owner and construction company, implementing related standards and codes and performing auxiliary experiment with effective measures to gather helpful experiences in the pipe pulling construction of large-diameter long-distance pipeline in rock areas in China.
