Floor embedded joint drainage device

A floor embedded connector drainage device in mechanical sealing connection comprises a floor embedded connector pre-arranged in a concrete floor and a connecting pipe movably connected with the floor embedded connector, and the floor embedded connector and the connecting pipe are directly and correspondingly provided with a sealing cavity structure used for installing a sealing piece. Aiming at the defects of inconvenience in later maintenance or easiness in water leakage caused by glue aging and insufficient pressure resistance of a sealing ring due to the fact that the existing floor embedded joint connection mode adopts glue bonding or socket connection, the floor embedded joint is suitable for occasions of PE (polyethylene) or PP (polypropylene) drainage pipes which cannot be bonded by glue. 一种机械式密封连接的楼板预埋接头排水装置，包括：预设于混凝土楼板中的楼板预埋接头和与之活动连接的接管，其中：楼板预埋接头和接管直接对应设有用于安装密封件的密封腔结构。本装置针对现有楼板预埋接头连接方式是采用胶水粘结或承插连接，不便后期维修，或因胶水老化、密封圈耐压不够导致容易漏水的缺陷，适用于不能采用胶水粘结的PE或PP排水管的场合。
