The invention relates to the manufacturing technology of a novel drainage pipe joint and a novel installation method used when the drainage pipe joint in applied. The method particularly comprises the steps that the drainage pipe joint is manufactured into a straight communicating pipeline with the length ranging from 15cm to 30cm; in addition, when the drainage pipe joint is manufactured, a whole inner cylinder is smooth without blocks; when the drainage pipe joint is applied to connection between two drainage pipes, the drainage pipe joint just needs to adhere and be fixed to the lower pipe, the upper pipe is directly installed in the drainage pipe joint without the requirement for gluing, and the operation is repeated until a whole drainage system is formed through connection. When land subsidence occurs, the upper pipe installed in the drainage pipe joint is large in telescopic space so that the pipes can not be broken; connection of the two pipes is not limited by time, operation can be conducted through one person independently, so that time and labor are saved and the drainage pipe joint is convenient to use and rapid in utilization; when one drainage pipe is blocked, sewage is automatically discharged from the portion, with no adhesion to the upper pipe, of the drainage pipe joint, and the phenomena that due to the fact that the drainage pipe is blocked and the sewage can not be discharged, the sewage overflows to a habitable room on the upper layer and pollutes the household environment are avoided.
