BIM technology-based accurate control method for thickness of road asphalt surface layer
The invention discloses a BIM technology-based accurate control method for thickness of road asphalt surface layer. The method comprises the following steps that after pavement base paving is completed, an unmanned aerial vehicle oblique photography technology or a three-dimensional scanner is used for creating a base three-dimensional BIM model, surface lofting control points are created in the base three-dimensional BIM model, and on-site lofting is conducted through a lofting robot according to the control points so as to trim the flatness of a base; a base layer three-dimensional BIM modelis created after flatness finishing, a final lofting control point of asphalt surface layer paving is determined, and paving of the asphalt surface layer is finished; a paved asphalt pavement three-dimensional BIM model is created, and an asphalt surface layer three-dimensional model is obtained through a difference set of the asphalt pavement three-dimensional BIM model and the base layer three-dimensional BIM model; accurate surface layer thickness data of any point can be obtained through the asphalt surface layer three-dimensional model so as to check whether the asphalt pavement thickness reaches the standard or not, and the construction quality is effectively controlled. The paving thickness of the asphalt surface layer can be effectively controlled, the paving quality is optimized,and the construction cost is saved.
本发明公开了一种基于BIM技术的道路沥青面层厚度精确控制方法，包括以下步骤：路面基层摊铺完成后，利用无人机倾斜摄影技术或三维扫描仪创建基层三维BIM模型，并在基层三维BIM模型中创建表面放样控制点，通过放样机器人根据控制点进行现场放样以修整基层平整度；创建平整度修整后的基层三维BIM模型，确定沥青面层摊铺的最终放样控制点，完成沥青面层的摊铺；创建摊铺后的沥青路面三维BIM模型，通过沥青路面三维BIM模型和基层三维BIM模型的差集得到沥青面层三维模型；通过沥青面层三维模型可以获得任意一点的面层厚度精确数据，以此检验沥青路面厚度是否达标，有效控制施工质量。本发明可以有效控制沥青面层的摊铺厚度，优化摊铺质量，节约施工成本。
