    • A device and a method for the production of multi-layer concrete pipes, particularly two-layer concrete pipes. The device has a first stand, in which a first pressing head that can be driven is mounted, a turntable, on which several mold mantles standing vertically can be pivoted into a stand in cycles, and a first charging system for filling a first concrete mixture into one of the mold mantles. A second pressing head having an outside diameter that is smaller than that of the first pressing head, and a second charging system for filling a second concrete mixture into one of the mold mantles are provided. In this manner, the second concrete mixture can be filled into the mold mantle, by the second charging system and the mixture can be distributed and compacted before the concrete pipe is removed from the mold mantle.
    • 一种用于生产多层混凝土管道,特别是两层混凝土管道的装置和方法。 该装置具有第一支架,其中安装有可被驱动的第一按压头,转台,其上垂直竖立的几个模具套筒可循环地枢转到支架中;以及第一充填系统,用于填充第一混凝土混合物 进入一个模具地幔。 提供具有小于第一按压头的外径的第二压头,以及用于将第二混凝土混合物填充到其中一个模具罩中的第二充填系统。 以这种方式,可以通过第二充电系统将第二混凝土混合物填充到模具罩中,并且可以在将混凝土管从模具罩移除之前将混合物分配和压实。

    • A concrete pipe making machine having a packerhead consisting of a rollerhead and a longbottom in which the rollerhead and longbottom are quickly assembleable and disassembleable as a unit from the packerhead drive means with one connector and brought into final adjustment off the machine, said drive means providing no obstruction to the flow of wet concrete toward the compaction area, the speed ratios between the rollerhead and longbottom being infinitely variable, and easily replaceable protective wear rings for precluding erosive deformation of the permanent parts of the machine due to undesired penetration of wet concrete into the longbottom.
    • 一种混凝土制管机,其具有由滚筒和长底部构成的封隔器,其中,所述滚筒头和所述底托以一个连接器从所述打包机驱动装置作为一个单元快速地装配和拆卸,并将其最终调整到所述机器上,所述驱动装置提供 不会阻碍湿混凝土流向压实区域,滚筒和长臂之间的速度比无级变化,并且易于更换的保护性耐磨环,以防止潮湿混凝土不希望的渗入机器的永久性部件的侵蚀变形 长凳。
