Problems solved by technology

[0004] The optimal wind resource is the target of wind farm site selection. Mountainous wind farm sites usually have steep terrain, lush vegetation, and sparsely populated, which brings great difficulties to wind farm road route selection and reconnaissance. At the same time, with the use of large wind turbines, Large-scale transportation brings another major challenge to mountain wind power. There is a large gap between manual survey and line selection and large-scale transportation
Therefore, the traditional two-dimensional road design of manual selection usually receives on-site feedback during the construction process and needs to be modified and designed repeate...

Embodiment

[0035] like figure 1 Described, a BIM-based road design method for mountain wind farms, the method includes the following steps:

[0036] S1: Collect wind farm GIS data and form a 3D model

[0037] Step S1 specifically includes:

[0038] S11: Collect the elevation, topography, geological conditions, ground features, existing roads, and vegetation information of the wind farm terrain through oblique photography;

[0039] S12: The establishment and import of the BIM model of the fan stand, power collection circuit, and fan platform;

[0040] S13: Build a three-dimensional model of the wind farm;

[0041] S2: Build a BIM 3D model of the road in the wind farm

[0042] Step S2 specifically includes:

[0043] S21: Complete 3 route selection schemes based on the 3D model of the wind farm

[0044] S22: According to the route selection plan, considering the turning radius and longitudinal slope required for large-scale transportation, carry out the road longitudinal section and f...

Abstract

The invention relates to a BIM-based mountain wind power plant road design method. The method comprises the following steps: S1, collecting wind power plant GIS data and forming a three-dimensional digital model; S2, constructing a road BIM three-dimensional model in a wind power plant; S3, conducting multi-scheme comparison and selection of roads in the field; S4, paying off a wind power plant road design scheme and feeding back on site; and S5, modifying and optimizing the road BIM model in the wind power plant. According to the method, all main and branch roads of a mountain wind power plant can be planned as a whole for overall design, transportation simulation of large pieces of fan blades is carried out, the problem of mutual influence between a current collection line and a road is solved, multi-scheme comparison and selection are carried out, and mountain wind power plant road design is carried out more accurately and more efficiently.

Description

technical field [0001] The invention relates to a road design method for mountain wind farms, in particular to a BIM-based road design method for mountain wind farms. [0002] technical background [0003] With the increasing development of wind power resources, high-altitude mountain wind farms using large-unit fans have become an important part of wind power resource development. [0004] Taking the best wind resources as the target of wind farm site selection, mountain wind farm sites are usually steep, lush vegetation and sparsely populated, which brings great difficulties to road route selection and surveying of wind farms; at the same time, with the use of large-unit fans, the Large-scale transportation brings another major challenge to mountain wind power, and there is a large gap between manual surveying and selecting lines and large-scale transportation. Therefore, the traditional two-dimensional road design of manual line selection usually receives on-site feedback...
