The invention discloses a steel sheet pile capable of reducing piling resistance and reinforcing stratum around the pile and a construction method, and relates to the technical field of design and construction of steel sheet pile supporting structures. The first conveying channel is arranged on the steel sheet pile body and used for synchronously conveying the soil softening agent to a designed position in the insertion process of the steel sheet pile body; and the second conveying channel is arranged on the steel sheet pile body and used for synchronously conveying slurry in the process of pulling out the steel sheet pile body. A soil softening agent is synchronously conveyed in the inserting and driving process, the stratum can be softened, the stratum resistance in the piling process can be reduced, the impact noise and energy consumption are reduced, the interference to the surrounding environment in the piling process is reduced, grout is synchronously conveyed in the steel sheet pile pulling process, pi
