【摘要】：北京市地下管線基礎(chǔ)信息普查——城六區(qū)第09片區(qū)普查項目覆蓋范圍廣泛,既包含城市中心區(qū)又包含郊區(qū)。對于相鄰電力檢修井之間存在轉(zhuǎn)折點的溝道,采用常規(guī)測量方法很難準(zhǔn)確、快速確定該溝道特征點的準(zhǔn)確位置。筆者所在單位技術(shù)人員積極改進(jìn)測量方法,在保證精度的基礎(chǔ)上創(chuàng)造性地提出使用全站儀自由設(shè)站、對中激光投點法,一次性將地面坐標(biāo)投至井下溝道內(nèi)代替聯(lián)系測量的方法,并在溝道內(nèi)采用無定向?qū)Ь�測量方法布設(shè)圖根控制點對電力溝道內(nèi)的特征點進(jìn)行測量。該方法快捷、方便、節(jié)省人力物力、大大提高了作業(yè)效率,是在溝道內(nèi)測量領(lǐng)域的一次創(chuàng)新。
[Abstract]:Beijing underground pipeline basic information census-the sixth district of the city of the 09 section of the survey project covers a wide range, including both the city center district and the suburbs. For the channel with turning point between adjacent electric overhaul wells, it is difficult to use the conventional measurement method to determine the accurate location of the channel characteristic point quickly. The technical staff of the author's unit actively improved the survey method, and creatively put forward the method of using the total station instrument to set up the station freely, put the ground coordinates into the underground channel instead of the contact survey method, and put the surface coordinates into the underground channel in one time instead of the contact survey method. At the same time, the characteristic points in the power channel are measured by the method of undirected traverse measurement. This method is quick, convenient, saves manpower and material resources, and greatly improves the working efficiency. It is an innovation in the field of measurement in the channel.
