Embodiment

[0061] Embodiment: A transmission line spanning construction method based on UAV modeling and BIM technology,

[0062] First of all, it is necessary to carry out on-site real-world 3D modeling:

[0063] 1) Planning and modeling scope: According to the design pole position information and retest records, separately generate a kml file for the route of the crossing section, import it into the DJI Map software, and adjust the required data in the DJI Map software according to the actual situation of the line. Modeling scope;

[0064] 2) Plan the modeling route: According to the modeling range, generate oblique photography routes, the number of routes in each direction and angle is not less than 5; and set the flight parameters of the UAV, such as completion actions, mission altitude, flight speed, course overlap rate , side overlap rate, photo ratio, white balance mode, gimbal pitch angle, etc.

[0065] 3) Oblique photography and real-scene photo collection: Import the set rout...

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...
