Background
The current detection technology applied to the interior of underground drainage pipelines comprises the following steps: pipeline Closed Circuit Television (CCTV), periscope detection technology, sonar, laser and other detection technologies.
The detection of the Closed Circuit Television (CCTV) of the pipeline is mainly realized by using a camera to enter a drainage pipeline to transmit image data to a control computer and then carrying out data analysis detection in a closed circuit television video recording mode. During detection, the water level in the pipeline needs to be temporarily reduced, and auxiliary work (such as temporary water transfer, plugging and the like) needs to be temporarily carried out for a drainage pipe network for detecting high-water-level operation. The CCTV robot transmits the collected images of the interior of the pipeline to a main controller in real time through a cable for real-time monitoring, detects and makes a video shot of the conditions of rust, scale, corrosion, perforation, cracks and the like in the pipeline, and then a trained professional judges video data to classify and grade the defects of the pipeline.
Periscope detection technology is a short-term test technique, utilizes adjustable length's action bars to carry high definition probe and puts into the inspection shaft, and the inside information of seizure pipeline that can be clear forms the video recording. The periscope is short in detection distance and incapable of detecting the water surface, and is used for detecting pipeline auxiliary structures such as short-distance pipelines or independent inspection wells. In practical application, periscope detection is often used in combination with CCTV detection technology for detecting pipeline auxiliary structures such as short-distance pipelines or independent inspection wells.
The pipeline sonar detection system adopts an acoustic method to detect the internal condition of a pipeline filled with liquid, does not need to drain the liquid in the pipeline, can generate a cross-sectional diagram of the pipeline, intuitively knows the general situation of sludge deposition in the pipeline, but cannot be used as the basis for judging the pipeline structure. Sonar detection is applied to the condition of ponding in the pipeline, and CCTV detects the supplement of means.
The laser detection technology is mainly used for detecting structural defects of the pipeline, such as geometric deformation, surface cracks, breakage and the like, can relatively accurately position the pipeline and identify the basic shape of the pipeline defect, and has the highest working efficiency in a completely dark environment because a laser beam can keep higher contrast under the dark condition, but brings difficulty for an operator to operate and control the machine.
The relevant documents include 01. Dengyueza 1, Liying 1, Zhang Guo 2(1. Beijing university of construction, major laboratory of urban rainwater system and water environment education department, Beijing 100032; 2. Beijing initiative GmbH, Beijing 100032).
Chinese patent publication No. CN103423596A discloses a drainage pipeline detection and evaluation method using a handheld video and a closed-circuit television, which includes performing preliminary detection using the handheld video, calculating and obtaining a pipeline deformation degree, a pipeline fracture/collapse degree, a pipeline interface dislocation degree, a pipeline protrusion interface/pipe penetration degree and a pipeline blockage degree by using detection data of the handheld video, classifying according to a standard according to a calculation result, and executing corresponding operations according to a classification result.
In view of the related art in the above, the inventors consider that the following problems exist in the above documents: (1) in the actual detection process, water vapor can be attached to the surface of a camera of the CCTV robot to form a fog screen, so that the observation, detection and recording processes of the CCTV are influenced. (2) The CCTV video interpretation process is complex, the workload is large, and the accuracy of the defect detection and interpretation practice is greatly influenced by the experience and skill level of workers; and is limited by the quality of the pictures and videos taken, some tiny cracks cannot be captured by the interpreters. (3) The traditional laser detection means at present is influenced by light, and an operator is difficult to operate the machine. In a dark environment, some micro-cracks are easily overlooked and the laser does not detect the inflow or outflow of water. The roughness of the tube wall surface can reduce the optical signal, thereby affecting the detection result. (4) The intelligent operation and maintenance management system is the direction of pipe network operation management, related engineering construction work is being done in the pipe network industry at present, the informatization degree of the traditional pipeline detection work is low, and the intelligent management process of the pipe network cannot be kept up with.
