Construction scheme for positioning, surveying and setting out of a passenger station in Fujian
1. Establishment of building plane axis control network. 2. Establishment of vertical control network. 3. Foundation construction survey, structure construction survey, decoration construction survey. 4. Settlement monitoring, soil lateral deformation measurement, maintenance structure deformation, foundation pit rebound observation, tower crane monitoring, data processing and analysis, and information feedback. 3 Main measurement methods 1. In view of the characteristics of the project, such as large single floor area, many construction projects, and great difficulty in construction measurement and control, the horizontal control network of the project is divided into two levels, the first level is the site horizontal control network, and the second level is the building axis control network. The establishment of the site horizontal control network is based on the control points provided by the Owner, and the number of reference points will be determined after the Owner provides them. The secondary control network adopts the rectangular coordinate method and polar coordinate method to measure and set the building control axis according to the field plane control network.
