A Bailey support system applied to cross protection of complex pipes and cables in an intersection tunnel, comprising:
- a type I suspension system,
- a type II suspension system,
- type III suspension systems that each have a same structure as the type I suspension system,
- a type IV suspension system, and
- a type V suspension system that has a same structure as the type II suspension system, and the type IV suspension system has a different structure from the type I suspension system, the type II suspension system, the type III suspension systems, and the type V suspension system;
- wherein the type III suspension systems are divided into four groups, two groups of the type III suspension systems are disposed on a front side of the type IV suspension system, and the other two groups of the type III suspension systems are disposed on a rear side of the type IV suspension system and are in one-to-one correspondence with the two groups of the type III suspension systems disposed on the front side, the type II suspension system and the type I suspension system are sequentially disposed on a left side of the type IV suspension system from left to right, and the type V suspension system is disposed on a right side of the type IV suspension system;
