The conditions of using hangar tunnel are roughly similar to those of open cavern, and its structural integrity is worse than that of open cavern, but the requirements for foundation are relatively low because the roof and inner and outer walls are briefly supported, and there are various types of hangar tunnel with different terrain and geological conditions, but its basic structure has inner wall, outer support structure and roof support structure. In the case of weak foundation conditions, the bottom support structure is also required, which is equivalent to the support beam of the culvert. The inner wall can be made into reinforced concrete slab wall and external support together to form a pile slab type supporting retaining wall. The outer wall support structure can be made into rigid frame type, column type and wall type according to the different terrain and geological conditions. The outer slab can be made of T-shaped beam, I-beam or hollow plate beam section prefabricated installation members. In order to prevent the hangar tunnel from being made, there may still be landslides, collapses and crumbling bodies into the hangar tunnel, the pile-slab type wall can be higher than the top lateral support structure, and in order to prevent the mudflow formed by the mountain from entering the hangar tunnel, green flexible protection is required on the side slopes, while intercepting ditches are set up on the high side slopes at the same time in a step every 8m.
