使用拖拉机碾压,在全国其它水利工程施工中,已取得成熟的经验,但在黄、沁河下游施工堤段长、坯头窄、土貭复杂的条件下,如何依靠拖拉机自重进行碾压,并达到经济合理的使用机械,目前仍属摸索阶段。1963年冬季在武陟、博爱的沁河修堤工程中,对拖拉机履带碾压进行了重点试验,通过实践,可以肯定拖拉机碾压具有很大的优越性,现依据实际体会,就碾压中的几个问题, The use of tractor roller compaction, in the construction of other water conservancy projects in the country, has gained mature experience, but in the Yellow River, Qinhe downstream embankment length, narrow head, soil 貭 complex conditions, how to rely on the tractor weight rolling, And to achieve economic and rational use of machinery, is still a groping stage. In the winter of 1963, a key trial of tractor crawler rolling was carried out in the project of Xiu River and Fraternal Cultivation of Qinhe River. Through practice, it can be affirmed that tractor rolling has great superiority. Based on the actual experience, Several questions,
