    • A process is provided for accessing an underground pressurized gas main for retirement of replacement of the connection of a gas service pipe thereto. A gas main fixture that has a service tee adaptor and a pressurized chamber connected thereto is mounted onto the gas main with the tee adaptor above a tee plug on the gas service pipe. The chamber is closed against gas discharge and the tee plug is unscrewed from the gas service pipe while the pressure chamber is closed. The tee plug is removed through the service tee adapter and pressure chamber while minimizing gas discharged to atmosphere. The plug hole is preferably reamed through the pressure chamber while the chamber is closed to atmosphere, tapped for a straight fine thread, and a main plug with the fine thread is screwed into the tapped hole while limiting its depth of engagement.
    • 提供了一种用于接近地下加压气体主体以退出更换燃气服务管的连接的过程。 具有服务三通适配器和与其连接的加压室的气体主夹具安装在气体主体上,其中T形接头适配器位于气体管道上的T型塞上。 在压力室关闭的同时,气室关闭气体排放,三通阀塞从燃气服务管中旋出。 通过服务三通适配器和压力室移除T型插头,同时尽量减少排放到大气中的气体。 插塞孔优选地通过压力室进行扩孔,同时将腔室关闭到大气中,敲击直线细线,并且将具有细线的主插头螺纹拧入螺纹孔中,同时限制其接合深度。

    • In a material transfer system, material from an excavation is drawn into a vessel by suction from a vacuum source. The vessel has discharge flaps at the bottom that are held closed by the suction. When the weight of the material in the vessel reaches a predetermined value, the flaps open and the material is discharged from the vessel. After the discharge, counterweights almost close the flaps and the suction seals the discharge flaps so that additional material is drawn into the vessel. The vessel includes a vibratory section and has sides that slope outwardly from top to bottom. The material entering the vessel contacts the vibratory section at a predetermined angle and is redirected to the discharge flaps without any caking on the vessel walls. The opening through the discharge flaps is larger than the inlet through which the material enters the vessel so that objects entering the vessel are discharged.
    • 在材料转移系统中,来自挖掘的材料通过真空源的抽吸被吸入容器中。 该船舶在底部有排放挡板,该排放挡板被吸力保持闭合。 当容器中的材料的重量达到预定值时,折片打开并且材料从容器中排出。 排放后,配重几乎关闭襟翼,吸力密封排放襟翼,以便将额外的材料吸入容器。 该容器包括振动部分,并具有从上到下向外倾斜的侧面。 进入容器的材料以预定角度接触振动部分,并且被重定向到排放瓣,而不会在容器壁上结块。 通过排放口的开口大于材料进入容器的入口,使得进入容器的物体排出。
