水泥砂浆衬里的现场整体施工与在工厂内单根管道预制相比,不仅省时省力而且省去了现场内补口工序,特别适用于长输管道的衬里施工。但由于过去挤涂器无分流和扶正装置,衬里厚度不均匀,为此研究设计了分流扶正式砂浆挤涂器。文中详细介绍了分流器的结构、设计及分流装置旋转速度的计算。采用这种挤涂器施工的水泥砂浆衬里,经检测,厚度偏差不超过2mm。 The overall site construction of cement mortar lining is not only time-saving and labor-saving but also eliminates the need for in-site filling process compared with single-pipe prefabrication in the factory. It is especially suitable for lining construction of long-distance pipelines. However, due to the past squeezer without shunt and righting device, the lining thickness is not uniform, for this study designed shunt mortar mortar coater. In this paper, the structure, design of splitter and the calculation of rotation speed of splitter are introduced in detail. Cement mortar linings constructed using this extruder are tested to a thickness deviation of no more than 2 mm.
