Outline
To address the challenges posed by traditional opencut methods in subway station construction, such as disruptions, shop demolitions, and relocation of underground pipelines, this study investigates the construction technology of jacking a rectangular tube for a subway station, focusing on the Haibang Station of the Guangzhou Metro Line 3 East extension project. Initially, three different combinations of pipe jacking schemes are proposed, each with unique characteristics tailored to the specific station engineering requirements. Selection among these schemes is based on practical considerations. Subsequently, the study details the section design, selection of jacking equipment, design of pipe sections, and implementation of waterproofing measures for the station. Finally, the feasibility of employing the combined pipe jacking method is validated through theoretical calculations and numerical simulations. The results demonstrate that the construction technology of jacking a rectangular tube for subway stations effectively addresses the challenges associated with underground pipeline integration. It ensures safety and feasibility in subway station construction. This approach offers a promising alternative to traditional methods, potentially minimizing disruptions and optimizing construction efficiency in urban environments.
