Power transmission line crossing construction method based on unmanned aerial vehicle modeling and BIM technology

Abstract

The invention discloses a power transmission line crossing construction method based on unmanned aerial vehicle modeling and a BIM technology. The method comprises the following steps: making a kml file according to the design and retest data in the initial stage of a project, and agreeing and determining a preliminary construction scheme in combination with a site survey condition; the RTK unmanned aerial vehicle is used for carrying out oblique photography route planning and live-action collection on the crossing site; a site-crossing refined three-dimensional model is generated by means of big Xinjiang intelligent graph software and intelligent 3D software; on the basis of the BIM technology, models such as an iron tower, a crossing frame and a blocking net are built and fused with the on-site three-dimensional model; carrying out a collision test, and optimizing the layout and the construction process; a BIM model dynamic demonstration function is utilized, a time axis is inserted according to a construction progress plan, and a BIM dynamic model is manufactured to carry out crossing scheme rehearsal and safety technical disclosure. According to the invention, the high-speed railway and the expressway can be regarded as an integral spanned object for simultaneous spanning construction, and the problems of site limitation and repeated entry and exit of personnel during respective spanning are solved.

Description

technical field [0001] The invention relates to a transmission line spanning construction method, in particular to a transmission line spanning construction method based on UAV modeling and BIM technology. Background technique [0002] With the vigorous development of my country's infrastructure projects, high-speed railways and expressways have spread all over the country, and the traffic network is densely covered. It is common for transmission lines to intersect and run parallel with high-speed railways and expressways at close distances. During the continuous spanning construction of transmission lines, The management units of the two crossed objects, the railway and the highway, the departments that approve the crossing and the time points of the crossing are different, which adds difficulty to the crossing construction. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to p...
