输煤栈桥和输煤廊道工程内常设置大量间距相等的预埋件,怎样准确地将它们安装在斜面上,多数施工单位还是沿用水准仪测量的方法。栈桥和廊道的坡度角一般为10°左右,而且长度较长,有时在同一个面的斜面长达100多米。如采用水准仪和经纬仪相配合的方法,可取得快捷和误差小的效果。具体 The coal trestle and the coal handling corridor project often set a large number of embedded parts with the same spacing, and how to accurately install them on the inclined plane, most construction units follow the method of level measurement. Trestle and corridor slope angle is generally about 10 °, and longer, and sometimes on the same side of the slope up to 100 meters. Such as the use of level and theodolite match the method, you can get quick and error-less results. specific
