PURPOSE:To obtain a composite function type gutter, in which initial polluted water is drained quickly, an outflow inhibiting function is controlled and improved, a storage space is ensured and a function recovery measure at the time of clogging is taken simply and which has a water control and intake function and a storage infiltration function. CONSTITUTION:A water control and intake post body 7, which is formed in an upper section closed type or a cover type and in which the whole surface is opened or a part is opened in a lower section and a plurality of intakes 9 are formed to a top section 8 projected near a center, is installed to the upper section of the sidewall of a gutter body 1, and the internal space of a gutter is divided into an upper drainage ditch 18 and a lower drainage ditch 19 by a bottom block 15 mounted to the intermediate section of the sidewall. Exchangeable filters 20a, 20b, 21 for preventing clogging are set up to the intakes 9 of the water control and intake post body 7, and an exchangeable sheet 22 for obviating clogging is laid on the opening section 5 of the bottom of the gutter.
