Abstract:

In order to solve problems of TBM equipment procurement, TBM management in the whole construction process, cutter and components supply, equipment maintenance and repair, and TBM major technical scheme demonstration for clustering construction project by multiple TBMs, the management mode and management experience of procurement and construction process operation control of 8 TBMs used in Liaoning Key Water Supplying Project are summarized. A centralized and unified management mode of TBM equipment with owner unit as the leading factor is put forward, i.e. the owner unit organizes contractors to conduct TBM centralized procurement bidding, participates in the whole process of TBM design liaison meeting, equipment supervision, onsite assembly and commissioning, trial operation, construction operation and other management work, establishes a mechanism of cutter and components supplying, leads the discussion and demonstration of TBM major technical schemes, and provides sufficient capital investment and technical support for construction contractors. The practice shows that the centralized and unified management mode mentioned above can provide strong technical support for normal operation of TBM equipment and guarantee the rapid construction.
