REVERSE SIPHON SEWER SYSTEM CAPABLE OF REDUCING COST AND MANPOWER

摘要

PURPOSE: A reverse siphon sewer system is provided to prevent deposits from being layered without additional drain equipment by simplified structure. CONSTITUTION: A reverse siphon sewer comprises a main pipe(10) having a connection pipe(11) and vertical pipes(12,14). An inlet pipe(20) and an outlet pipe(30) are each connected to the vertical pipes. A bypass-sub pipe(15) having the caliber smaller than the caliber of the main pipe is connected to a lower side of the vertical pipe and to the end of the outlet pipe. The height of the upper end of the bypass-sub pipe is lower than the height of the water level of sewage flowing into the vertical pipe. The connection parts of the vertical pipe of the main pipe and the outlet pipe are interconnected by a slant pipe(18) having a proper rake angle.
