A method and system for survey and calculation of construction area

Abstract

The invention discloses a construction area survey and calculation method and a system, belonging to the technical field of building construction, which comprises the following steps of: using an unmanned aerial vehicle to investigate the early construction of a highway and a railway, investigating the early demolition area, and obtaining the surrounding environment of the area to be constructed and the building conditions to be demolished. Using BIM software to establish the BIM model of the area to be constructed, the BIM model and the surrounding environment model of the area to be constructed are matched in space, and the virtual reality scenes that can be experienced are obtained, and the removal evaluation and preliminary construction investigation are carried out on the basis of thevirtual scene. The invention can quickly and accurately carry out multiple surveys and calculations on the construction area to be constructed during the surveying period, and meets the requirementsof large outdoor construction area, changeable construction environment and complex surveying planning for multiple times.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction area survey and calculation method and system. Background technique [0002] In the infrastructure construction, due to the large outdoor area and the changeable and complex environment in the early stage of highway and railway construction, it is necessary to plan the surrounding environment in the early stage of construction and calculate the specifications of the buildings that need to be demolished. [0003] The traditional method is that the surveyor releases the centerline of the pipeline and the well position according to the design drawings, and releases the sideline of the foundation pit according to the centerline of the pipe and the excavation requirements of the foundation pit. Surveyors need to calculate the height difference between the existing elevation and the design elevation, remove the elevation difference, mark on the designed pil...

AI Technical Summary

Problems solved by technology

Uncertainty in the preliminary design of highway and railway projects and the unpredictability of some projects in the construction process have affected the strength and depth of the overall planning of project land use, resulting in the need for multiple surveys and plans for demolition areas and tight survey schedules

If the traditional method of relying on surveyors for survey planning is adopted, it will consume a lot of manpower and material resources, and the survey efficiency is low, which cannot meet the variability requirements of the construction area, and it is difficult to complete the survey within the specified construction period
