Drainage pipe capable of effectively reducing infiltration line in side slope body

The utility model discloses a drain pipe capable of effectively reducing a seepage line in a side slope body, which is formed by combining a reinforcement cage pipe wrapped with geotechnical cloth (2), and the reinforcement cage pipe comprises four longitudinal support steel bars (3) with equal length and transverse support wire rods (5) which are arranged at equal intervals. And the four longitudinal supporting steel bars (3) with the same length are respectively welded on the inner sides of the transverse supporting wire rods (5) which are arranged at equal intervals in an upper, lower, left and right manner to form a steel bar cage pipe. The structure can well achieve the seepage drainage and precipitation functions in the slope body, effectively reduce the seepage line in the slope body, reduce the number of drill holes, optimize the slope treatment scheme and save the investment cost, has the advantages of being easy and convenient to construct, high in reliability and strong in water permeability, the d
