Concealed culvert detection and layout method

Abstract

The invention belongs to the technical field of underground box culvert detection and layout facilities, and particularly relates to a concealed culvert detection and layout method. The layout methodcomprises the following steps that 1) a cable end of a cable winding and unwinding vehicle is connected with a three-way conversion joint on a detection robot; 2) the detection robot enters the box culvert; 3) a power supply and other devices on the detection robot are started through a ground control station; 4) the ground control station controls the detection robot to walk in the box culvert ashore and acquires images in the box culvert; 5) the detection robot collects images and data and feeds back the images and data to the ground control station; 6) an operator pulls the detection robotout of the box culvert through the ground control station; (7) the detection robot is pulled out of a municipal wellhead, and the operator separates the cable end from the three-way conversion joint on the detection robot; and (8) the separated detection robot waits for detection of the next box culvert. The method has the advantages that the workload before operation is reduced, and 360-degree detection of the interior of the box culvert is achieved.

Description

technical field [0001] The invention belongs to the technical field of underground box culvert detection and rowing facilities, and in particular relates to a method for detecting and rowing hidden culverts. Background technique [0002] In recent years, most cities in China suffer from waterlogging every time there is heavy rain. Urban waterlogging has become one of the important problems facing the development of Chinese cities. [0003] Urban drainage pipes discharge more and more waste water and waste all year round, and these substances are also corrosive, which in turn causes various functional and structural damages such as blockage and leakage of urban drainage pipes. [0004] Therefore, timely detection of drainage pipes is necessary to predict various hidden dangers in the pipe network in advance, and provide accurate implementation basis for pipe dredging, repair, municipal planning, engineering quantity calculation, and emergency measures. [0005] Urban box cul...

AI Technical Summary

Problems solved by technology

[0005] Urban box culverts are used as the confluence pipe network of various drainage pipes, and there are more or less rainwater and sewage inside almost all of them. Therefore, if the traditional periscope method is used for detection, it can only detect the internal conditions at a short distance, and it will be disturbed by the water body. lead to poor shooting

[0006] If the traditional pipeline CCTV crawling robot is used, it is necessary to block water and cofferdam the box culvert, and drain the rainwater inside the box culvert or pump it to a low water level before performing corresponding detection operations. The early operation process is cumbersome and the operation is not easy convenient
