- 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。
Comparing with cement lining prefabrication on several pipes has advantages in not only sav-ing time and labour but also exempting, to a great extent, the in-situ joint inner patching proce-dure. Therefore, it is specially suitable for lining construction on long distance pipeline.However,the old air blow compressive smearing unit has neither flow diverter nor central correctorto make lining thickness uniform. So a new one with flow diverter and central axial corrector isdeveloped. This paper introduces in detail the structure, design andcalculation on turning speed ofthe diverter.The resultant thickness tolerance of cement lining, after measuring, is not larger than 2mm by using the new unit.1992,1(1): 15-17 收稿日期：1992-12-5
