PIPE TRAP, AND WASTE WATER PIPE STRUCTURE
To provide a pipe trap highly effective in suppressing deterioration of sealing function.SOLUTION: A pipe trap 10 comprises: an inflow side piping connection portion 36 that causes waste water flowed to the pipe trap 10 to flow downward; a first downward curved pipe portion 38A that is provided below the inflow side piping connection 36 and curves downward from the upper side in the vertical direction to the horizontal direction; a first upward curved pipe portion 38B that is provided at a position downstream of the first downward curved pipe portion 38A and curves upward to the horizontal direction from the vertical downward direction; a second upward curved pipe portion 42A that is provided at a position downstream in the waste water direction, of the first upward curved pipe portion 38B and curves upward from the downside in the vertical direction to the horizontal direction; a second downward curved pipe portion 42B that is provided at a position downstream in the waste flow direction of the second upward curved pipe portion 42A and curves downward from horizontal direction to a downside in the vertical direction; and a pressure relaxation device 66 that is placed at the upper side than the second downward curved pipe portion 42B and communicates with the second downward curved pipe portion 42B to relax the pressure inside the pipe.SELECTED DRAWING: Figure 3A
【課題】破封を抑制する効果が高い管トラップを提供すること。【解決手段】管トラップ１０は、流入した排水を下方へ向けて流す流入側配管接続部３６と、流入側配管接続部３６の下方に設けられ、鉛直方向上側から水平方向に向けて下向きに湾曲する第１下り湾曲管部３８Ａと、第１下り湾曲管部３８Ａの排水下流側に設けられ、水平方向から鉛直方向上側へ上向きに向けて湾曲する第１上り湾曲管部３８Ｂと、第１上り湾曲管部３８Ｂの排水方向下流側に設けられ、鉛直方向下側から水平方向へ向けて上向きに湾曲する第２上り湾曲管部４２Ａと、第２上り湾曲管部４２Ａの排水方向下流側に設けられ、水平方向から鉛直方向下側へ向けて下向きに湾曲する第２下り湾曲管部４２Ｂと、第２下り湾曲管部４２Ｂよりも上側に配置され、第２下り湾曲管部４２Ｂに連通して管内の圧力を緩衝する圧力緩和装置６６と、を備えている。【選択図】図３Ａ
