<p>PURPOSE:To realize water collection with high efficiency by providing the water collecting device which is adequate for collecting the water to be treated with a purification treatment by a sewage purification treating device with a discharge means in the upper part of a perforated pipe body and providing the lower part at the closed end of this pipe body with discharge means. CONSTITUTION:The water collecting pipe 6 as the water collecting body to be laid in the bottom of a water storage tank or an artificial pond or the like installed in a golf course consists of the cylindrical pipe body 4 made of vinyl chloride formed with many water passage holes 8 on the peripheral surfaces on both sides in the horizontal direction along the longitudinal direction. One end of this pipe is closed by a cap body 5 and the other end is connected to a main pipe arriving at the purification treating device. Air holes 10 as discharge means through which gas, such as air, can flow out, are formed on the upper peripheral surface on the side of the pipe body 4 closed with the cap body 5. Drain holes 11 as discharge means through which fine sand, etc., can flow are formed in the lower part at the end face of the cap body 5. A net body 12 is put on the outer peripheral surface to prevent the clogging of the holes 8, 10 by foreign matter.</p> |
