The invention discloses a town road edge permeable blind ditch and a construction method thereof. The permeable blind ditch comprises a blind ditch channel, the bottom of the blind ditch channel is paved with a concrete supporting layer, a water collecting pipeline is placed in the blind ditch channel along the longitudinal direction of the blind ditch channel and positioned on the concrete supporting layer, the blind ditch channel is filled with a permeable concrete layer, the upper portion of the permeable concrete layer is paved with an asphalt surface layer, the water collecting pipeline is in the shape of a cylinder, a plurality of water guide channels shaped like regular hexagonal prisms are distributed in the cylinder and arranged along the longitudinal direction of the cylinder, a plurality of limber holes are formed in the side wall of the cylinder and distributed along the circumferential direction and the longitudinal direction of the cylinder, each limber hole is communicated with at least one water guide channel through a water channel, and each water guide channel is communicated with at least one adjacent water guide channel through water channels. A road surface above the blind ditch can be stable and firm, and rainwater discharge force can be enlarged as compared with a traditional blind ditch.
