SEAL PIT FOR DRAINAGE
PROBLEM TO BE SOLVED: To provide a seal pit for drainage with an inexpensive and sufficient defoaming effect.SOLUTION: A seal pit for drainage 100 comprises: a drain pipe 1 which has a drain outlet 11 to discharge drain water; and a weir 2 which is a partition between a water storage area A1 in which the drain water discharged from the drain pipe 1 is stored and a discharge area A2 to which the drain water in the water storage area A1 is discharged, and has an open hole 23 to communicate the storage area A1 and the discharge area A2 below a lowest water level LWL of the discharge area A2. A flow channel cross sectional area S of the open hole 23 is set so that the drain outlet 11 is located below the level of the drain water stored in the water storage area A1 and the level of the stored drain water does not exceed the height of the weir 2 even when the maximum amount of drain water is discharged.SELECTED DRAWING: Figure 2
【課題】低廉かつ十分な消泡効果を備える排水用シールピットを提供する。【解決手段】排水を排出する排水口１１を有する排水管１と、排水管１によって排出される排水が貯水される貯水域Ａ１と貯水域Ａ１の排水が放流される放流域Ａ２とに区画するとともに、放流域Ａ２の最低水位ＬＷＬよりも下方に貯水域Ａ１と放流域Ａ２とを連通させる貫通孔２３が形成された堰２と、を備え、貫通孔２３の流路断面積Ｓは、排水口１１が貯水域Ａ１に貯水された排水の水位よりも下方に位置するように、かつ、最大排水時であっても貯水された排水の水位が堰２の高さを超えないように設定されている排水用シールピット１００。【選択図】図２
