1.Ensure that the trolley strength is reasonable, so that the vault and side wall of the secondary lining are smooth and level without false platform, making the front and rear rings overlap smoothly, and the low side wall is straight.
2.Finite analysis and calculation are used to optimize the structure under stress. On the premise of ensuring the strength, the steel consumption of the trolley and the construction cost are reduced.
3.Implement standardized transformation, use a large number of standard parts, promote the universality of the trolley, and improve the reuse rate
4.Promote humanization and automation of trolley, reduce labor cost, improve construction efficiency and reduce construction risks.
