摘要
在城市高层建筑桩基础施工中,现多采用旋挖钻机施工桩基础,由于受场地、吊车和旋挖钻机施工等的影响,全站仪放样往往受通视条件的限制,不利于桩位的放样和检核,尤其是夜间施工。本文结合个人的工程测量教学和实际施工测量经验,将具体阐述HBCORS系统在高层建筑桩基放样中的应用优势。
In the city,we usually use rotary drilling rig in the construction of the pile foundation in high-rise building. Be-cause of the influence of space, the construction of the crane and rotary drilling rig and so on, total station lofting is not conducive to loft and check the pile position by the restriction of the visibility conditions, especially in the night. This pa-per combines the experience of the teaching in the engineering survey and the practical construction to explain the practical advantage of the HBCORS system in the pile positioning application.
