accomplishment of yards, squares, gardens, parks, etc. SUBSTANCE: invention relates to devices for collecting and draining water from road pavements. It can be used in forming pedestrian zones, sidewalks, bicycle lanes, etc. proposed surface member of rain water diversion channel has rain water intake chute made of concrete. It has rectangular profile of outer surface and u-shaped profile of inner surface. Novelty is that side boards are arranged in top part at a distance of 4.5-5.5 t relative to each other. Height of boards is chosen from range of 2.5-3.5 t. side boards in profile taper in inner surface at angle of 9°÷12° towards the bottom, being mated in radius, and minimum thickness of bottom of rail water intake chute is chosen from range of 0.9-1.1 t. EFFECT: simplified technology of manufacture of rain water intake chute owing to preset geometry, increased service life. 4 cl, 7 dwg
