Large-scale project on-site planning method

Abstract

The invention discloses a large-scale project on-site planning method. The method comprises the following steps: building a preliminary terrain model through employing B M + G S, and building a plurality of site arrangement schemes on the basis of the combination of the preliminary terrain model + a high-definition satellite mixed graph and site survey; an unmanned aerial vehicle oblique photography technology is utilized, a live-action model serves as basic data of project planning, an accurate digital terrain is provided for three-dimensional design, temporary construction scheme design is carried out, and project overall temporary construction function partitioning is planned; three-dimensional visualization is taken as a means, cost control is taken as a main line, selection ratios are carried out from the aspects of technology, organization and traffic demands, and a final planning scheme is determined. The problems that in the background art, large projects, especially mountain projects, are large in temporary building number, large in site construction area, short in temporary construction period, high in environmental protection requirement and the like are solved, and the problems that the advantages and disadvantages of schemes are difficult to distinguish and arrangement schemes are more difficult to find in the earlier stage in a traditional mode of combining on-site exploration with plane layout drawings are solved.

Description

Technical field[0001]The present invention relates to the technical field of project planning methods, in particular, involving a method of playing a large project.Background technique[0002]The planning and design of the construction project is the basis and premise of the project's top construction. Unlike the construction industry, large-scale comprehensive projects, especially the honestop of the mountains, and the gully. Among them, the tunnel engineering has a unique feature of "strip-shaped distribution, limited to natural factors". At the same time, the mountain project is increasingly complex, there is a multi-line long, the safety and civilization construction and environmental protection requirements are high, and the level of refined management Backward problems. The traditional large-scale mountain project is planned, side design, side modification, side construction, limit two-dimensional, static mode, often occurs in temporary land and space utilization rate, on-site i...

Problems solved by technology

To solve the shortcomings of traditional temporary construction site selection and design, such as long time-consuming, heavy field workload, and low design efficiency, it belongs to the field of construction engineering

However, this invention can only use "BIM+GIS" technology to realize the preliminary design of the temporary construction project, without precise coordinate positioning, let alone the comprehensive expression and transmission of the overall planning information on the project site, and has not yet reached the level of construction depth guidance
