在总图设计中,竖向布置及土方平衡是不可缺少的工作之一,而在竖向布置及土方平衡工作中,很大一部分时间花在求插入标高的工作上,因此影响了工作效率。为此,我们根据工作的需要,搞了这个计算板。由于工作体会不深,经验不足,所以在工具本身还有缺点。这里我们将这个计算板介绍一下,供各兄弟单位有关同志参考和研究,以便进一步改进。(一)用途(1)若已知任何两点的标高后,则可查出两点间任何一点之标高。在目前总图工作中,可用来查两点间的设计标高及平均自然标高。(2)在测量工作中可以帮助确定等高线的位置。(二)构造(1)在三角透明板上刻上与底面及右侧面平行之
In the layout design, vertical layout and earthwork balance are indispensable ones. In the vertical arrangement and earthwork balancing work, a large part of the time is spent on the work of inserting elevations, thus affecting work efficiency. To this end, we have carried out this calculation board according to the needs of the work. Because the work experience is not deep and inexperienced, there are still disadvantages in the tool itself. Here, we will introduce this calculation board for reference and research of relevant comrades in each fraternal unit for further improvement. (I) Usage (1) If any elevation of any two points is known, the elevation of any point between two points can be found. In the current general map work, it can be used to check the design elevation and average natural elevation between two points. (2) It can help determine the position of the contour line in the measurement work. (B) Structure (1) Inscribed on the triangular transparent plate parallel to the bottom surface and the right side surface
