Chenzhou City for the first time for urban roads to do routine "physical examinations"

"This is the first time in our city to do a regular" physical examination "for urban roads. As a result, I found some problems ..." On July 6, Zhou Liang, deputy general manager of Chenzhou Municipal Engineering Corporation, received the "CT "The test report results," Suxian North Road found 6 empty caves, 9 off the empty, 34 grass -roots loose places, 2 empty caves in Yanquan Road, 2 off the empty, 1 grass -roots loose, and 24 places in Nanling Avenue. "

In recent years, due to transportation loads, geological conditions, leakage of underground pipeline networks, and top pipe construction, the roads will produce diseases such as subsidence and damage during use, which seriously threatens citizens' travel safety and urban operation order. However, underground caves are often unable to find through the naked eye, which increases the difficulty of preventing road collapse.

At 14:00 on June 22, asphalt pavement collapsed at the auxiliary road at the auxiliary road 20 meters before the intersection of the urban area of ​​Luzhou City. After the danger, the Municipal Urban Management Bureau rushed to the scene for the first time, requiring the Municipal Municipal Engineering Corporation to quickly organize personnel and machinery and equipment to block the scene, analyze the reasons to formulate a repair plan, and investigate the three pairs of water sections in the urban area.

In order to prevent unexpected road collapse, the Municipal Municipal Engineering Corporation took the initiative to invite professional teams to conduct comprehensive "physical examinations" of the main roads in urban areas, investigate underground caves and other diseases, early warning, ensure road safety traffic, and protect the safety of citizens' feet.

Three -dimensional radar comprehensive inspection vehicle travels on Nanling Avenue

At around 22:00 on June 25, a three -dimensional radar comprehensive inspection vehicle slowly traveled on Nanling Avenue. The vehicle is equipped with the "PhalanX -dense array disease scanning system". Through three -dimensional geological radar, high -density surface waves and other high -tech detection technology, it can detect diseases such as 6 to 8 meters under the road, which is equivalent to "CT, MRI Nuclear Magnetic Magnetic Magnetic Magnetic Magnetic Resonance.

"Through the real -time collection system of the car, you can see road conditions, working conditions and data collected. This is the original data. You can see the underground pipelines, structures and other facilities. You can see some abnormalities. In the later period, professional and technical personnel will be by professional technicians. Processing, analysis and interpretation of the three -dimensional data, screening out abnormal areas without missing any source of risks. "Jiang Suyang, manager of the Shengsheng Science and Technology Area, said," Combining technical means such as satellite positioning, photography imaging, etc. Verify diseases such as underground caves. At the same time, information such as the distribution, geometric size, deepness and net high of the cave and other information, and timely feedback information to provide a basis for the treatment of the disease. "

This "medical examination" has tested a total of three roads including Nangling Avenue, Yanquan Road, and Suxian North Road. The preliminary inspection, review, on -site drilling verification, and analysis road data area was about 82,000 square meters. Through detailed and precise testing, a total of 78 diseases were found in this calculation.

"In the next step, according to the results of the test, the corresponding repair plan will be formulated according to the test results, and daily inspection and monitoring will be strengthened to general diseases." Zhou Liang said that using high -tech detection technology, fast and accurate detection and disposal of underground cavities Waiting for diseases, improve the level of refined management of municipal infrastructure, improve the sense of security and happiness of the people, serve the high -quality development of the city, and provide powerful technical services for the city's road network reconstruction of the city's large -scale quality central urban area.
