The YD2100 Rock Pipe Jacking Machine has been deployed for the Wong Tai Sin Drainage Improvement Project in Hong Kong, facilitating the upgrading of regional municipal water infrastructure. As one of the core construction machines for the project, the equipment delivers stable and reliable overall performance together with precise jacking control, successfully completing rock jacking works along its designated section. It ensures orderly project progress with high-standard construction quality, demonstrating the comprehensive competitiveness of domestically manufactured pipe jacking equipment for high-end municipal projects in Hong Kong.
The Wong Tai Sin Drainage Improvement Project in Hong Kong is a key municipal livelihood project, which plays a vital role in improving the regional stormwater drainage system, enhancing urban flood prevention capacity and optimising the layout of underground pipelines. The project adopts stringent construction standards and rigorous process planning. A total of four advanced pipe jacking machines are deployed to construct approximately 1,500 meters of pipe jacking tunnels within an estimated construction period of 1,520 days. The tunnel section constructed by the YD2100 Rock Pipe Jacking Machine has an average overburden depth of around 10 meters. With a diameter of 2.1 meters, the machine launches from Shaft 1633 and advances accurately to Shaft 04 to complete an 84-meter rock crossing. Extremely high requirements are imposed on rock tunnelling precision, tunnel profile quality and construction stability, resulting in prominent challenges for refined construction.
To meet the rigorous construction schedule and cope with rock-crossing conditions of this Hong Kong municipal project, our YD2100 Rock Pipe Jacking Machine exhibits outstanding working condition adaptability and construction accuracy. Designed to satisfy large-diameter tunnel construction requirements, the machine features a robust structure and ample power output. It has undergone targeted performance optimisation for local rock formations, enabling precise control over jacking attitude and excavation alignment. The equipment effectively addresses construction challenges such as fluctuating excavation resistance and tunnelling deviation during rock driving, fully complying with high-standard municipal engineering codes in Hong Kong and meeting the refined and standardised construction requirements for deeply buried rock tunnels.
Throughout construction, the YD2100 Rock Pipe Jacking Machine operated smoothly with precise manipulation and strong stratum adaptability. It accurately accomplished the 84-meter rock jacking drive from Shaft 1633 to Shaft 04. The tunnel profile remained regular throughout the works with qualified construction quality and zero safety incidents. Capable of meeting the project’s long-cycle and standardised construction requirements, the machine advanced all jacking procedures steadily and fulfilled the planned rock-crossing task, laying a critical foundation for the smooth delivery of the overall 1,500-meter tunnel works.
The successful application of the YD2100 Rock Pipe Jacking Machine in the Wong Tai Sin municipal project fully verifies the equipment’s stable performance and precision advantages for rock-crossing works in urban municipal water projects, highlighting the overall competitiveness of our pipe jacking machinery for high-end overseas municipal contracts. This project further expands the track record of domestic pipe jacking equipment in Hong Kong, accumulates valuable practical experience for urban stormwater pipeline upgrading and long-period multi-machine coordinated jacking, and continuously supports the high-quality development of municipal infrastructure in Hong Kong and Macao.
