Construction method of residual slope wash tunnel with shallow cover and unsymmetrical pressure
The invention relates to a construction method of a residual slope wash tunnel with a shallow cover and the unsymmetrical pressure. The scheme with the step of ground surface grouting and shotcrete anchorage combined supporting, the step of pre-reinforcement of a long pipe shed and the step of correction three-stair four-step excavation construction is adopted, construction is conducted layer by layer from outside to inside, and operation that the deep-cover unsymmetrical pressure side is excavated, supporting is conducted, then the shallow-cover unsymmetrical pressure side is constructed, and an asymmetrical initial supporting structure is used for conducting construction according to the unsymmetrical pressure of surrounding rock is conducted, so that the supporting structure is optimized, the working procedure is more reasonable, and the construction speed is increased.
