在农田水利建设中,常常要碰到曲线测设的事情,例如琉浚河道、砌石护岸、渠道等工程的定线·按照一般的方法,首先要用径纬仪测出转角,然后经过复杂的计算,再用径纬仪放样,限于仪器缺少,手续繁复、施工检查复测也嫌太慢,所以一般农民技术员难于采用这个方法。我县自六四年以来在农田水利建设中一直采用一个简易的曲线测设法,测设曲线时,不需要径纬仪,只要用花杆,皮尺,在现场进行
In the field of farmland water conservancy construction, we often encounter the problem of curve measurement and setting, for example, the setting of Liujian River, masonry revetment, channel, etc. According to the general method, we first measure the rotation angle with the caliper and then the complicated Calculations, and then stomathematical lofting, limited to the lack of equipment, complicated procedures, construction inspection retest is too slow, so farmer technicians difficult to use this method. Since 1964, our county has adopted a simple curve measurement method for farmland water conservancy construction. When measuring curves, we do not need anodolite, so long as we use flower pole and tape measure to carry out on-site
