METHOD AND APPARATUS FOR COMPUTERIZED FLUSHING OF HUMAN EXCRETA ON TRAIN TRACKS AT TRAIN STATIONS FOR 100 HYGIENE RAILWAY STATIONS IN ABSENCE OF MANUAL LABOR FOR CLEANING HUMAN EXCRETA

摘要

Fig 9A a conception aimed at eliminating human excreta on train tracks debouched from train carriage (22). The said purpose is achieved through implementation of two fundamental computer numerically controlled mechanical apparatuses Viz trench opening and closing assembly (12) and trench flushing apparatus (18). The trench (8) constructed between rails (11) throughout the maximum permissible length of train at railway station platform. The effluent into the trench is flushed through flushing apparatus (18) mounted on the side wall of the trench. Thus the two fundamental apparatuses (12) and (18) operated from station master computer control through the interface of servo motors, servo drives, PLC and station master computer control in combination with retention tank (28) and holding valve (29) develop train station platforms 100% free from human excreta to restrict bacterial spread and to eliminate 21st centurys disgusting manual labor adoption in cleaning human excreta at train stations.
