    • A system for laying a subterranean water impervious asphalt layer which is mounted on a tractor and includes a liquidized asphalt supply tank and a subterranean plough provided with a plurality of outlet ports so that liquidized asphalt is fed from the tank through a liquidized ashalt supply pipe connecting the tank to the ports by a liquidized asphalt supply pump provided in the pipe and driven by a hydraulic motor so that liquidized asphalt is discharged by the ports to form a water impervious asphalt layer into a subterranean cavity. The system is provided with a hydraulic pump driven by an engine of the tractor and connected to the hydraulic motor and a switching valve provided in the lines connecting the hydraulic pump to the hydraulic motor so that the hydraulic motor is driven in the forward or reverse direction as well as is held standstill by the actuation of the switching valve. The system is provided with a washing tank containing cleaning liquid therein, and the tank is switchingly connected to the tank through a two-way switching valve so that the pipe and the ports can be cleaned by the cleaning liquid by operating the two-way switching valve. The system further comprises a burner for heating asphalt in the tank which is supplied with fuel from the fuel tank of the engine through a fuel supply pipe by the actuation of a cock provided in the fuel supply pipe.
    • 一种用于铺设地下不透水沥青层的系统,其安装在拖拉机上并且包括一个液化沥青供应罐和一个设有多个出口的地下犁,使得液化沥青通过一个液化的灰渣供给管连接 通过设置在管道中并由液压马达驱动的液化沥青供应泵将罐装入端口,使得液化沥青通过端口排出,以形成不渗水的沥青层进入地下空腔。 该系统设有由拖拉机的发动机驱动并连接到液压马达的液压泵和设置在将液压泵连接到液压马达的线路中的切换阀,使得液压马达沿正向或反向驱动 并且通过切换阀的致动而被停止。 该系统设置有在其中容纳清洗液体的洗涤槽,并且罐通过双向切换阀切换地连接到罐,使得管和端口可以通过操作双向开关由清洗液清洁 阀。 该系统还包括用于加热罐中的沥青的燃烧器,其通过设置在燃料供给管中的旋塞的致动通过燃料供给管从发动机的燃料箱供给燃料。
