ROOF DRAIN AUXILIARY DEVICE BY PUMP PRIMING SIPHON TUBE
To discharge rainwater accumulated in rainfall automatically and swiftly to remove trouble due to the rainwater retained for a long period near a drain pipe of a flat roof or the like not allowing a frequent access as the drainage of the retained water of the flat roof is prevented due to a height of a framework of trash elimination grid normally installed at an entrance of a vertical pipe for a building drainage as a barrier, and to solve such a problem with a retrofitting simple tool without a careful design of a roof structure in a new construction stage or a reconstruction in a large scale.SOLUTION: A siphon tube extending from a bottom of retained water is inserted inside deeply of a vertical tube for drainage, rainwater in rainfall is accumulated up to a high position by a check valve, this allows an activation of the siphon tube as a pump priming, thus enables the drainage over a drainage vertical tube entrance grid position higher than a water level of the retained water.SELECTED DRAWING: Figure 2
【課題】頻繁にアクセスできない陸屋根等の排水管付近に長期に滞留する雨水による弊害を取り除くために降雨の際に溜まる雨水を自動的かつ速やかに排出することが求められる。陸屋根の滞留水は建物排水用縦管の入口に通常設置されるごみ除けの格子の枠組の高さが障壁となって排水が阻害されるためである。これをなくすには、新築段階での屋根構造の周到な設計あるいは大掛かりな改築が必要であるが、ここでは後付けの簡便な道具で解決したい。【解決手段】滞留水の底から伸びるサイフォン管を排水用縦管の内部深くに通し、降雨時の雨水を逆止め弁で高い位置まで貯め、これを誘い水としてサイフォン管を起動させることにより、滞留水の水位より高い排水縦管入口格子位置を超えて排水させる。【選択図】図２
