The invention discloses leakage water guiding drainage structures used in a tunnel and a tunnel middle wall and a construction method, belongs to the technical field of municipal engineering urban tunnel structure design and construction, and the purpose is to solve the problem that existing tunnel leakage cannot be collected and discharged into a drainage structure of a tunnel in an effective path. The leakage water guiding drainage structure of the middle wall comprises a longitudinal water collecting ditch formed in the top of an anti-collision side stone, a plurality of diversion drainageditches are formed in the outer surface of the anti-collision side stone, and longitudinal gutter apron drainage ditches are formed in a gutter apron beside the bottom of the anti-collision side stone. The leakage water guiding drainage structure of a side wall comprises plain concrete, the plain concrete is arranged at the bottom of a maintaining roadway and has transverse slope and the slope istowards drainage side ditc
