Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] Such as Figure 1-3 As shown, a fast detection system for tunnel construction section form includes a data acquisition module and a data analysis module. The data acquisition module is composed of a control center, a leveling control center, a laser transmitter 16 and a carriage vehicle 30. The leveling control center includes Control part, CPU 3, level sensor 33, pressure sensor 10, FPGA4, DCA5, servo driver 6, servo motor 7 and lifting legs 9 symmetrically distributed on both sides of the bottom of the carriage 30.
[0033] The control center is arranged in the machine head 27, including a camera group 8 composed of 4 industrial fixed-focus network cameras, a control part, an A / D converter 14, an FPGA 4, a DCA 5, a central processing unit 3, and a servo driver 6;
[0034] The camera group 8 is fixed on the front surface of the machi...

The invention discloses a tunnel construction section shape fast detection system and a detection method thereof. The tunnel construction section shape fast detection system includes a data acquisition module and a data analysis module. The data acquisition module is composed of a control center, a leveling control center, a laser transmitter, and a carrier trolley. The data acquisition module acquires image information through a camera group. The data analysis module is responsible for storing data and splicing, fitting, calculating and analyzing tunnel image data in the later stage. The invention further discloses a method for tunnel construction section detection using the tunnel construction section shape fast detection system. Non-contact measurement of construction tunnel section deformation and section over-break and under-break is realized. The problem that the identifier is easy to damage and the measurement tool is inconvenient to hang in the traditional detection method is overcome. The detection system is convenient to operate. The detection efficiency is improved. The risk of long-time operation on a tunnel construction site is reduced.
Description
technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a rapid detection system and detection method for tunnel construction section form, in particular to a one-time shooting method for reflecting the construction section form of mountain tunnels using ring laser lines as auxiliary structural light sources. A detection system and a non-contact measuring method thereof. Background technique [0002] With the continuous development of the social and economic level and the continuous improvement of people's requirements for the quality of life, the scale and quantity of China's transportation and engineering construction are generally showing a growing trend. Moreover, our country is a mountainous country, whether it is the construction of expressways or railways, a large number of tunnels are needed to meet the needs of speed, line and line type. [0003] The construction of mountain tunnels usually adopts the m...
