The design turning radius of the pipeline is required to be less than 40m. The starting well diameter is 10m, and the main geology is gravel cobble. Construction difficulties include ultra-small turning radius, complex geological formations, and small starting wells.
For this project, our partner has carried out many innovative designs, such as small diameter spherical hinges, ball hinge spiral screw conveyor, ultra-small turning radius belt conveyors, and one click switching soil improvement devices.
This shield tunneling machine has an excavation diameter of 3.05m and can achieve a super-small turning radius of 35m, making it the smallest diameter earth pressure balance shield tunneling machine in China at present.
