The invention relates to an elbow and drain pipe structure. The elbow is provided with: an inflow-side pipe connection section (36) through which the inflowing drainage water flows downward; a first downward elbow section (38A) provided below the inflow-side pipe connection section and bent downward in the horizontal direction from the upper side in the vertical direction; a first upstream elbow section provided on the downstream side of the first downstream elbow section, the first upstream elbow section being bent upward from the horizontal direction to the upper side in the vertical direction; a second upstream elbow section which is provided on the downstream side of the first upstream elbow section in the drainage direction and which is bent upward in the horizontal direction from the lower side in the vertical direction; a second downward elbow section provided on the downstream side of the second upward elbow section in the drainage direction and bent downward from the horizontal direction to the lower side in the vertical direction; and a pressure relief device that is disposed above the second downward elbow section, communicates with the second downward elbow section, and buffers the pressure inside the pipe.
本发明涉及弯管和排水管构造。弯管包括：流入侧管道连接部(36)，其供流入的排水朝向下方流动；第1下行弯曲管部(38A)，其设于流入侧管道连接部的下方，从铅垂方向上侧朝向水平方向向下弯曲；第1上行弯曲管部，其设于第1下行弯曲管部的排水下游侧，从水平方向朝向铅垂方向上侧向上弯曲；第2上行弯曲管部，其设于第1上行弯曲管部的排水方向下游侧，从铅垂方向下侧朝向水平方向向上弯曲；第2下行弯曲管部，其设于第2上行弯曲管部的排水方向下游侧，从水平方向朝向铅垂方向下侧向下弯曲；以及压力缓和装置，其配置于比第2下行弯曲管部靠上侧的位置，与第2下行弯曲管部连通而缓冲管内的压力。
