Cutting combination construction method for full-section hard rock contact channel

The invention discloses a cutting combination construction method for a full-section hard rock contact channel. The cutting combination construction method comprises the steps that S1, construction preparation is conducted; s3, manual breaking of a left line; S4, drilling of a right line through a water drill; S5, combined excavation of a pump room; and S6, manual trimming of an air pick. Compared with a traditional excavation method, the connection channel cutting combined construction method has the advantages that rope saw cutting, manual breaking and water drill hole taking are utilized for construction, channel penetration can be rapidly completed, the size of an excavation face is effectively controlled, the influence on ground buildings is reduced, civilized construction and good utilization of various resources are facilitated, and the construction efficiency is improved. A good foundation is laid for subsequent construction, and good economic benefits are generated; in addition, the invention provide
