The concentrating pipe extends in the longitudinal direction of the tanker and is connected with a bottom valve of the tank. The drain pipe extends in the width direction of the tanker below the concentrating pipe and is provided with drain ports at both ends thereof. The connection part is branched from the concentrating pipes, is connected with the drain pipe through a head valve of a pump provided with opening and closing valves at both sides. The rear drain pipe has an end part provided with a drain port rearwardly of the tanker. The rear drain pipe is branched from the drain pipe and extends rearwardly toward the end part through the opening and closing valves and tilts downward. The bypass pipe is branched from the connection pipe and is connected with the drain pipe through the opening and closing valves. COPYRIGHT: (C)2006,JPO&NCIPI
