以前我们在作四等点(包括插点在内)的造标埋石工作时,都是按照大比例尺测量规范草案附录2进行的,由于缺乏经验,造的觇标很笨重,成本又很高,以后虽对个别地方作了修整(如缩小櫓柱的腰径等),但还不够理想.今年我们做了一个试点,在标石上竖以木制花桿代替觇标,试用效果良好,茲将此方法介绍于下,供同志们参考.花桿是以5公尺长的木桿涂以油漆制成,木桿应 In the past, when we were working on quarrying buried stones for the fourth class (including interpolation points), they were all done in accordance with Appendix 2 of the large-scale measurement specification draft. Due to lack of experience, the target was very cumbersome and the cost was high. Although we have done some repairs to individual areas (such as narrowing the mandrel’s waistline, etc.), this is still not ideal. This year, we did a pilot project and put a wooden flower pole instead of the standard on the target stone. This method is introduced in the following for reference by comrades. The flower pole is made of paint with a 5-meter long wooden pole. The wooden pole should be
