Method for managing remedied earthwork volume of polluted site by combining aerial survey of unmanned aerial vehicle and BIM technology

Abstract

The invention provides a method for managing remedied earthwork volume of a polluted site by combining aerial survey of an unmanned aerial vehicle and BIM technology comprising the following steps: using an unmanned aerial vehicle to carry out data information acquisition on a polluted site, exporting unmanned aerial vehicle data, and in three-dimensional modeling data processing software, outputting point and line data with elevation properties, based on the soil color, the vegetation coverage condition and the position of the waste residue and waste material pile, obtaining an approximate region boundary of the polluted site; collecting soil samples on points near the boundary line to acquire a boundary of an accurate polluted site area importing the data into revit software to generate a three-dimensional original terrain model, and establishing a BIM model; and based on the BIM model, obtaining information data such as excavation work amount, excavation boundary, depth and the like of earthwork, and realizing full-process management and control of a polluted site remediation project. The unmanned aerial vehicle is used for obtaining the panorama of the whole polluted site and generating the three-dimensional live-action model, and the three-dimensional live-action model is combined with the BIM model, so that the manual measurement modeling cost is greatly reduced, the timeliness and authenticity of the polluted site repair construction process are improved, and the requirement of three-dimensional visualization progress comparison is met.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a method for managing the amount of earthwork for remediation of polluted sites by combining aerial surveying with UAV and BIM technology. Background technique [0002] In recent years, the scale of large and medium-sized cities across the country has continued to expand, and urban construction land is insufficient. Therefore, the government has relocated some chemical companies from the suburbs to the outer suburbs, and then converted industrial land into construction land. However, the long-term production of chemical companies has caused soil pollution in the factory area. Before relocating the factory area to build residences and business districts, the contaminated soil needs to be restored and backfilled. According to the "Soil Environmental Quality-Soil Pollution Risk Control Standards for Construction Land (Trial)" (GB36600-2018), the construction land includes the first t...
