The shape of the shield tunneling tool must adapt to the characteristics of the construction geology, and its function and requirements are different at different positions of the cutting section. Therefore, the tool should be designed accordingly.

① The cutting efficiency of shield tunneling tools in sand and gravel formations, that is, how to reduce cutting resistance and ensure the fluidity of cutting soil.

② By changing the shape of the cutting tool, the wear of the shield tunneling tool can be reduced and the durability of the tool can be improved.

③ To meet the needs of construction in bustling urban areas, efforts should be made to minimize the interference of the rotating cutting tool of the cutterhead on the surrounding soil and environment, such as vibration, noise, etc.

④ How to propose practical and feasible measures from the aspects of materials and design to solve the wear and tear of cutting tools (including impact and falling blocks) during shield tunneling in sandy and gravel formations, ensuring the reliability of shield tunneling tools for long-distance excavation.
