Abstract

PURPOSE:To smoothly drain water by eliminating the intrusion of leaves and shingle or the like into a water passage through water passing holes of a draining concrete pipe, and to obtain the excellent permeability by eliminating the penetration of cement paste into a permeable member at the time of manufacture. CONSTITUTION:A draining concrete pipe C is formed into a square cylindrical shape and provided with an upper wall 1, side walls 2, 3 and a bottom wall 4 to form a water passage 7 inside thereof. Five housing materials 5 are embedded in the upper wall 1 with an equal space. Each housing material 5 passes through the upper wall l and formed into a flat cylindrical shape, of which lower side is narrowed a little. A hook member is projected inside from the inner wall of the housing material 5, and a hook member is projected outside from the outer wall of the housing material 5. The housing material 5 is made of vinyl chloride, which can not be penetrated with cement paste. The housing material 5 is filled with the permeable member 6. The permeable member 6, which is obtained by solidifying grains of natural stones such as rutile with the binder, is formed with multiple irregular permeable clearances passing through from the upper surface to the lower surface to smoothen the permeation of the water content of rainwater or the like.
