During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.

在宁波市北渡－雅戈尔原水D1800mm钢管复线工程顶管施工中，出现主顶动力站顶力异常增大的现象，影响继续顶进施工，文章针对这一情况进行分析研究，通过理论顶力曲线与实际顶力曲线以及工具管所经轨迹与管道在土层中静止时的形态图的分析比较，得出主顶动力站顶力过大是因为在纠偏过程中纠偏角度过大，使管道在短距离内过度弯曲引起的。

The manufacture of copper core of automobile radiator includes coating tinned or bared copper cooling pipe; roasting assembled main core inside braze welding furnace at 230-280 deg.c for 30-60 sec; welding main sheet to cooling pipe via conventional process; and welding the copper lid opening for the water chamber with brazing agent without solder and welding filament.
