The utility model relates to a duplex drainage standpipe and a system. The system comprises the duplex drainage standpipe in the building and a manhole at a lower end. The duplex drainage standpipe comprises a first drainage standpipe and a second drainage standpipe, which are arranged side by side and are communicated. The lower ends of the first drainage standpipe and the second drainage standpipe are communicated into the manhole. The utility model further provides the duplex drainage standpipe correspondingly. The utility model uses the design of the duplex drainage standpipe. Each standpipe serves as a drainage pipe and an exhaust pipe at the same time, which are mutually replaced and supplemented. Unbalanced pressure in the standpipe is eliminated instantaneously. The problems of pumping water, water jump and spraying water are solved. At the same time, the situation in which harmful gas is leaked out because of the damage of a choke is avoided. Moreover, the building drainage system does not need a vertical gas pipe and reduces the use of transverse gas pipes as much as possible, consequently the construction cost is reduced and the appearance of the building is improved.
