The construction time of the secondary lining is determined according to the monitoring and measuring data, the tunnel lining of the class III surrounding rock section is properly closely followed with the primary support, and the inverted arch and backfilling are carried out before the secondary lining; the secondary lining of the IV-class surrounding rock can be delayed properly and is applied after the primary support is basically stable. And constructing a waterproof layer and a plastic blind pipe according to design requirements before lining. The waterproof layer and the plastic blind pipe are constructed by a self-made operation trolley, and the waterproof layer is welded and fixed by hot welding by a nail-free laying process. The lining in the tunnel adopts the full-section construction of a traversing hydraulic lining trolley, 1 trolley is respectively matched at the inlet end and the outlet end of the tunnel, the factor that the tunnel is positioned on a curve is considered, and the trolley with the length of 9m is selected. After the lining of the whole tunnel is finished, the lining concrete of the emergency stop belt is additionally provided with a movable 3015 steel template with an arc shape in a trolley steel mould, and a special comb-shaped mould is used for reinforcing and adjusting the size, and pedestrians, a driving cross hole and other reserved holes are constructed by adopting a special rack. The concrete is S8(C25) waterproof concrete, the concrete is transported by a concrete mixing transport vehicle (more than 200 m), the concrete is pumped by a delivery pump to be poured into a mold, and the concrete is intensively mixed by a mixing station. At tunnel construction kind, along with the propulsion in tunnel, can inwards install fixed lighting apparatus gradually additional, when nevertheless constructing unreinforced tunnel wall, often adopt interim lamps and lanterns to throw light on, this kind of interim lamps and lanterns light source angle is fixed, uses the dumb, and it is more to plant the shadow at the work progress, can cause great influence to the construction.
