Mechanical Method Construction Scheme for Ultra-long Connection Channels in the Composite Formation Area
To address the challenges of high risk and extended construction periods associated with conventional methods for building long-distance connection channels,this study introduces a mechanical method in the composite formations of South China for the first time.Research focused on the overall project plan,selection of construction methods,equipment choices,and segment structure design,which led to the successful implementation of the project based on these findings.The following conclusions can be drawn:the mechanical method of connecting channels can solve engineering problems with long distances,large angles,and large inclinations and is applicable to composite formations in South China;it is feasible to change the assembly method of pipe segments from radial insertion to longitudinal insertion followed by radial insertion,by modifying the pipe segment design scheme.
