Problems solved by technology

[0003] The pipe gallery generally adopts a reinforced concrete structure. Due to factors such as construction, load, temperature change, uneven settlement, and concrete shrinkage, when the deformation energy inside the concrete material is too large, macroscopic cracks will occur, reducing the durability and safety of the structure. bring great danger

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail in conjunction with the following. It should be understood that the details described here are only used to explain the present invention, and are not intended to limit the present invention.

[0019] Below in conjunction with accompanying drawing and specific application principle of the present invention will be further described:

[0020] Such as figure 1 As shown, a detection method for cracks in underground utility tunnels, the implementation process includes the following steps.

[0021] First, image collection of pipe gallery. Use a drone to take aerial photos of the pipe gallery that may have cracks, and input the collected images into the computer.

[0022] Second, process the image of the pipe gallery. Since the detection of crack information does not require a color image, first extract the gray value o...

Abstract

The invention provides a method for detecting the cracks of an underground integrated pipe gallery. First, an image of a pipe gallery is collected; then, the image is filtered, sharpened, enhanced andthe like through a computer, the crack width is calculated, and the crack depth is detected through an ultrasonic pulse method; and finally, crack information is gathered. The image of the pipe gallery is collected by an unmanned aerial vehicle, so that the flexibility of collection is improved, manpower and material resources are saved, and the efficiency of information collection is greatly improved. The image analysis process can be implemented by computer programming, and the program is very easy to transplant and can be used unlimitedly. The detection method is automatic and intelligent.The detection result is accurate and reliable.

Description

technical field [0001] The invention belongs to the field of municipal infrastructure engineering, in particular to a method for detecting cracks in concrete structures of pipe galleries. Background technique [0002] The pipe gallery is the storage space for various underground comprehensive pipelines (water, electricity, heating, communication, etc.) in the city. With the gradual development of the social economy, the urban land is becoming more and more tense. The rational development and utilization of underground space is an important aspect of future urban construction. direction. The construction of pipe corridors is conducive to the rational layout of various pipelines and long-term operation and maintenance. Therefore, in recent years, a number of urban comprehensive pipe corridors have been built in my country. [0003] The pipe gallery generally adopts reinforced concrete structure. Due to factors such as construction, load, temperature change, uneven settlement,...
