FIG. 1
[0001] The present invention relates to, and more particularly, relates to a tunnel measurement and control method based on a combination of a three-dimensional laser scanner and a BIM.
[0002] At present, in tunnel construction, with the continuous development of the industry information technology, high-precision detection, pre-control and construction have become a trend. For use of traditional methods: a. in a radar nondestructive testing method, it is difficult to measure higher parts such as tunnel vaults, the amount of data collected is small, the accuracy is low, the efficiency is low, and the operation is inconvenient; and b. although a method of detecting construction deviation with a cross section instrument improves the effect relatively, the elevation and plane accuracy are difficult to control, the efficiency is still slow and the limitations are large. According to the above situation and the characteristics of tunnel construction, the phase-type three-dimensional laser scanner is combined with the BIM technology, which can achieve high-precision and high-efficiency tunnel measurement and control, make up for the defects of the traditional methods, solve the problems of tunnel measurement and control and realize the measurement and control effects of tunnel over-excavation and under-excavation, secondary lining thickness and structural deviation.
[0003] The purpose of the present invention is to overcome the defects in the prior art and propose a tunnel measurement and control method based on a combination of a three-dimensional laser scanner and a BIM, so as to solve the difficult problems of a traditional tunnel measurement and control mode and realize efficient and accurate measurement and control for tunnel over-excavation and under-excavation, secondary lining thickness and structural deviation.
[0004] The purpose of the present invention is achieved by the following technical solution.
[0005] A tunnel measurement and control method based on a combination of a three-dimensional laser scanner and a BIM in the present invention comprises the following steps:
[0006] step 1: conducting three-dimensional point cloud scanning in a tunnel at each stage to obtain point cloud data;
[0007] step 2: splicing, denoising and coloring the point cloud data by using professional point cloud software to obtain optimized point cloud data models at various stages;
[0008] step 3: building a tunnel structure model by using BIM parametric modeling software;
[0009] step 4: importing the point cloud data models and the tunnel structure model into third-party visualization software for comparison and analysis, and simultaneously realizing monitoring and advanced pre-control through cross section analysis.
[0010] In the step 1, a phase-type three-dimensional laser scanner is used for conducting three-dimensional point cloud scanning.
[0011] In the step 2, the professional point cloud software uses reverse modeling software.
[0012] Compared with the prior art, the technical solution of the present invention brings the following beneficial effects:
[0013] The present invention uses the combination of the three-dimensional laser scanner and the BIM technology to conduct comparison and analysis of reverse modeling and forward modeling, so as to achieve high-precision and high-efficiency tunnel measurement and control, make up for the defects of the traditional methods, solve the difficult problems of the traditional tunnel measurement and control mode and realize the measurement and control effects of tunnel over-excavation and under-excavation, secondary lining thickness and structural deviation.
[0014] The present invention overcomes various defects such as small data collection, low precision, low efficiency, inconvenient operation, large limitations and the like in the existing measurement and control mode in tunnel construction, and realizes efficient and accurate measurement and control for tunnel over-excavation and under-excavation, secondary lining thickness and structural deviation.
[0015] Fig. 1 is a flow chart of a tunnel measurement and control method based on a combination of a three-dimensional laser scanner and a BIM of the present invention.
[0016] In order to make the method of the measurement and control process of the present invention and advantages clearer, the present invention will be further described below in detail through specific embodiments. The specific embodiments described herein are only used to explain the present invention, and not to limit the present invention.
[0017] As shown in Fig. 1, a tunnel measurement and control method based on a combination of a three-dimensional laser scanner and a BIM of the present invention is specifically realized as follows:
[0018] Step 1: in all stages, e.g., before blasting, after the first support and after secondary lining, three-dimensional point cloud scanning is conducted in a tunnel to obtain point cloud data.
[0019] Further, before measurement, a tripod and a reference control point need to be surveyed. At the same time, according to the characteristics of the tunnel construction, a phase-type three-dimensional laser scanner needs to be selected here, which is more accurate than other methods. The phase-type three-dimensional laser scanner is used for segmented measurement, and a target ball is arranged at the splice to reduce the measurement deviation. At the same time, the phase-type three-dimensional laser scanner has a true color camera which can restore the original appearance of the tunnel to the greatest extent in post-processing.
[0020] Step 2: the point cloud data is spliced, denoised and colored by using professional point cloud software to obtain optimized point cloud data models at various stages, wherein the professional point cloud software uses reverse modeling software, such as Scene.
[0021] Step 3: a tunnel structure model is built quickly and accurately by using BIM parametric modeling software such as Dynamo.
[0022] Step 4: the point cloud data models and the tunnel structure model are imported into third-party visualization software for comparison and analysis; over-excavation and under-excavation positions and structural deviation positions are marked; and simultaneously, monitoring and advanced pre-control can be realized through cross section analysis, thereby realizing review of tunnel over-excavation and under-excavation, secondary lining thickness and structural deviation.
[0023] Although the functions and the working process of the present invention are described above with reference to the drawings, the present invention is not limited to the above specific functions and working process. The above specific embodiments are only schematic, not restrictive. Under the inspiration of the present invention, those ordinary skilled in the art can make many forms without departing from the spirit of the present invention and the scope of the claims, and these forms belong to the protection scope of the present invention.
