Foundation pit inspection operation method based on three-dimensional laser scanning technology
The invention relates to the technical field of civil engineering, in particular to a foundation pit inspection operation method based on a three-dimensional laser scanning technology. The method comprises the following steps: 1, scanning a foundation pit in construction through a data acquisition module to obtain foundation pit point cloud data; 2, transmitting the obtained foundation pit point cloud data to a single monitoring data processing module; 3, point cloud registration and data segmentation are carried out through a single monitoring data processing module, and three-dimensional laser point cloud data are processed and analyzed; and 4, performing over-excavation judgment and alarm, excavation speed judgment and alarm and newly added water seepage judgment and alarm through a monitoring data comparison analysis and alarm module. The three-dimensional position coordinates and the reflectivity obtained by the laser scanning device are fully utilized, high-precision over-excavation recognition and progress monitoring and reliable leakage water and gushing water and accumulated water recognition are achieved, monitoring elements do not need to be buried, a measured target does not need to be contacted, and the foundation pit construction inspection workload is reduced.
本发明涉及土木工程技术领域，尤其涉及一种基于三维激光扫描技术的基坑巡检作业方法。本发明包括以下步骤：第一步：通过数据获取模块对施工中的基坑进行扫描，以获取基坑点云数据；第二步：将获取的基坑点云数据传输至单次监测数据处理模块；第三步：通过单次监测数据处理模块进行点云配准、数据分割，对三维激光点云数据进行处理分析；第四步：通过监测数据对比分析及报警模块进行超挖判断及报警、挖方速度判断及报警和新增渗水判断及报警。本发明充分利用了激光扫描设备获取的三维位置坐标和反射率，实现了高精度超挖识别和进度监测、可靠的渗漏水和涌水积水识别，且无需埋设监测元件，无需接触被测目标，降低了基坑施工巡检工作量。
