Abstract

PURPOSE: To securely inject only a planned quantity of chemicals and reduce losses of material by using a timer previously set to perform the operation of a pump, the change-over of valves, the introduction of pressurized air or the like according to the injection quantity of chemicals into the rear surface of lining and the volume of washing water.
CONSTITUTION: Device surrounded with an broken line 25 are mounted on a car truck capable of travelling in a propulsion tube (lining) 27. In the devices, agitation baths 12A and 12B for liquids A and B are connected to the suction side of equivalent pumps 14 and 14 through liquid/water change-over valves 13 and 13 respectively. The pumps 14 and 14, which have the same capacity and can be driven by an electric motor M, suck and deliver the same quantity of liquid, so that the liquids A and B from the baths 12A and 12B are joined together in a confluence pipe 16, and mixed sufficiently before being delivered 17 to an injection discharge change- over valve 20. By the change-over operation of the valves 13 and 13, water 9 is delivered to the valve 20 through the same courses as the liquids A and B, washing them. The chemicals delivered to the valve 20 is injected into tail void 26 through an injection pipe 18, and surplus chemicals and washing waste-water are each automatically returned to a washing waste-water tank 22 through an exhaust pipe 19.
