PROBLEM TO BE SOLVED: To provide a gravity flow type sewer pipe capable of restricting the conditions becoming anaerobic.SOLUTION: The gravity flow type sewer pipe includes: a pipe; and an overflow weir. Sewage flows through the pipe. The overflow weir is formed protruding upward from the inner peripheral surface of the pipe for allowing sewage to flow down over the weir. The upstream side plane of the overflow weir has a guide part which extends upward toward the downstream side.SELECTED DRAWING: Figure 1
【課題】嫌気化を抑制できる自然流下式下水管を提供することである。【解決手段】実施形態の自然流下式下水管は、管路と、越流堰と、を持つ。管路は、下水が流通する。越流堰は、管路の内周面から上方に向けて突設され、下水を下流側に越流させる。越流堰の上流側を向く面は、下流側に向かうに従い上方に向けて延びるガイド部を有している。【選択図】図１
