The invention provides a high-voltage copper bar processing technology for overcoming stamping slump, including the following steps: product fixing: fixing the high-voltage copper bar to the lower mold; bending: using the pressing of the upper mold and the lower mold, Bending from the middle, flattening: use the upper mold flattening punch to flatten the straight parts at both ends of the bent high-voltage copper bar; fine cutting: use the fine-cutting punch to flatten the two ends of the high-voltage copper bar after the flattening step The straight part is fine-cut; the product falls: the high-voltage copper bar that has been fine-cut and deburred is taken out from the lower mold. The high-voltage copper bar processing technology provided by the present invention to overcome the punching slump angle adopts the fine cutting process after the high-voltage copper bar is flattened and thinned, and the fine cutting will cut off the outwardly extending part vertically, effectively avoiding The problem of slump angle; finally, when injecting glue, it not only avoids glue running, but also fully guarantees the contact area of ​​high-voltage copper bars, thereby ensuring the electrical performance of high-voltage copper bars after glue injection.

The invention relates to a process for constructing a substrate dam of a refuse dump, which comprises the following steps that: (1) a ladder-shaped substrate dam is constructed vertical to the gradient direction of a refuse dump within the range of the refuse dump, wherein the substrate dam is constructed by hard stone blocks and concrete, and the substrate dam is an isosceles trapezoid; (2) the position of the dam foundation of the substrate dam is provided with a water drain hole, and the position of the water drain hole of the substrate dam at the bottommost position of an elevation is excavated with a water drain ditch; and (3) a water guide ditch is excavated between the water drain ditch and a water accumulation pool, an outlet of the water drain ditch of the substrate dam is connected with the water guide ditch, an outlet of the water guide ditch is connected with the water accumulation pool, and the water of the water drain ditch is gathered at the water accumulation pool by the water guide ditch.
