Reporter squatting 丨 Shandong "Smart River Governance": New equipment for flood prevention is the edge of the Yellow River

All the pontoon bridges were demolished, and the drones were hovering from time to time. The "orange vest" shaped frequently on the embankment ... In the past few days, the traffic in the Shandong section of the Yellow River continued to rise. Real combat requirements are actively preparing for the front line of flood prevention.

On July 1, the Yellow River Basin entered the main flood season, and the river affairs departments along the yellow level had fully launched the defense flood operation mechanism on June 19. This year is the 21st year before the Yellow River flooding. Different from the past, Shandong has opened a new model of "wisdom to the river" this year, and promotes the organic combination of new technological means and traditional river management model to build the Yellow River Anlan Anlan. More solid barrier.

The stone seams can be seen clearly

On June 28, the Qihe and Yellow River Affairs Bureau's Xiaoyi Lili managed the flood prevention and drought -resistant combat room. The monitoring screens from 36 cameras continued to switch on the large screen to monitor the changes in river potential, dyke, and insurance workers in real time.

"Today's traffic has risen to 3,400 cubic meters per second. During the water adjustment period, the maximum traffic of the Texas section is about 4,000 cubic meters per second." Li Jianfeng, deputy director of the Xia Bali management section Encryption frequency. "

"After every morning meeting, a full -scale video surveillance inspection will be conducted." Chen Chengxin, an engineer on duty on the day of the Xiaobali management section, kept an eye on the screen, constantly switching the camera's picture back to the screen, enlarged and reduced important project points. "Mainly depending on the collapse and deformation of Tanshi Po, whether the root stone is collapsed, or if there is any damage to the anti -stone, there are no players in the beach ..." With the continuous movement of the mouse in Chen Chengxin's hand, the full picture of the river section is large, small to the dam of the dam, The stone cracks of the root stone are clearly seen.

"Video surveillance facilitates daily inspection and management. Once there is a dangerous situation, the monitoring screen can be shared through the video service system. At the same time, it can be reported to the superiors more intuitively." On the basis of this year, 6 newly installed. At present, all the projects in the area under the jurisdiction have basically achieved full coverage of video surveillance. "Especially in conjunction with the recent cross -strait lighting project, the monitoring effect at night is no less than the day."

Solved the difficulty of some engineering inspections

On one side, 36 points were monitored 24 hours a day, and on the other hand, Gao Daolin, an employee responsible for drone inspection, was conducting equipment debugging. On June 28, the drone inspection was opened on time on time.

"The corner of the drone is flexible, more three -dimensional and intuitive, especially the embankment land, beach areas, and silt areas with complex road conditions, and the inspection of drones can be seen." Gao Da Lin told reporters that according to water adjustment adjustment, according to water adjustment adjustment During the sand period, the drone inspection was once every morning in the afternoon. If you encounter a large flood like last year, you need to encrypt the inspection.

This year, the Shandong Yellow River Affairs Bureau put the grass -roots (institute) video surveillance system, drone inspection, and "three full coverage" of the "three full coverage" of the video conference discussions system as a key task. "When the superiors come to investigate, we can report the management section of the management system through the video conference business system in the combat room." Li Jianfeng said, "We can receive the spirit of the superior meeting as soon as possible, but also convey to every in the management section as soon as possible Employees, the cost of the meeting is almost zero. "

The continuous improvement of informationization is making the Yellow River more intelligent and more efficient. But can these new equipment replace the front -line dike to check insurance? the answer is negative. "According to the current traffic meter, three dikes are still conducted every day." Li Jianfeng told reporters.

"The Yellow River is muddy, and the underwater situation can be judged by monitoring or the naked eye. It must be judged by the root stones." Li Bin, an employee of the 37 -year -old Xiao Bali management section, has been working on the front line of the Yellow River for 15 years. "This year With more video surveillance and the cooperation of drones, our pressure can be reduced, especially those where you can clearly judge the problem through monitoring, you can appropriately reduce the frequency of inspection. "

According to statistics, since the fall of last year, the river affairs departments at all levels of Shandong have added 1027 video surveillance, drone 95 driving, and 89 video conference terminals. Improved work efficiency.

Optical measurement sand measuring real -time monitoring content content content

The flood prevention of the Yellow River is different from other rivers, not only flood prevention, but also sand prevention. Today, the means of flood prevention are increasingly intelligent, and how the sand prevention is effective?

On June 29th, at Jinan Hyoupes Hydrastial Station, which was more than 20 kilometers downstream of the Xiaobali management section, stopped on the shore's ship test, and the staff was debugging the newly introduced photoelectric sand measurement instrument. "This is currently the first photoelectric sand test in the Shandong section of the Yellow River. Today, I tested it. The data is quite accurate." Wang Xiangming, deputy head of the Hydrological Station, was excited.

The sand content of the Yellow River must be measured on weekdays. During the water regulation, the frequency of reports should be added. "At present, the horizontal sampler is measured. You need to open the ship to measure the five -point water sample in the river. After mixing, put it in the laboratory for 24 hours. "Wang Xiangming told reporters that the sand content reported in this way is the actual data of the previous day. "And the photoelectric sandmeter can realize the online real -time monitoring of sand content. Through the sand content data of each 6 minutes, technicians can master the entire process of sand content, which greatly saves manpower."

The so -called water adjustment is to use the dry tributary reservoir to regulate the process of entering the downstream water and sand process, shape a relatively coordinated water and sand relationship, reduce the storage of the reservoir river, and restore and maintain the Zhongshui river tank. How to schedule the reservoir and how much the flow of the lower leakage is not without precise hydrological data. Wang Xiangming told reporters that during the water regulation and sand and sand, water levels, flow, single sand, water depth, section average flow rate, measurement point flow rate and other data must be reported every day. At present, information technology such as radar water level meter, video surveillance, ADCP current, and automatic flood reporting system can realize the functions of automatic collection, transmission, processing, display, and hydrological data analysis, and commercialization of hydrological elements. "But you still need to measure the traffic data on the spot every day to check the relationship line of automatic flood reporting software. When encountering a particularly large sand content, you need to go out to test. The more important, the more accurate." Obviously.

The ability of the main river slot to be overcurrent is significantly improved

How effective is the effect of water and sand and sand? Wanpeng, the head of the Houkou Hydrastial Station, showed the station's transformation of the main river slot's overcurrent ability change from 2002 to 2021: "For example, under the level of 28 meters, the corresponding flow in 2002, 2008, and 2020, respectively, about 1200 cubic cubic meters, respectively. Mi/second, 2500 cubic meters/s, 3800 cubic meters/s, this shows that the ability of overcurrent has a significant rise. "

Wan Peng more vividly compared with flood floods last year and floods in 1996: In 1996, the maximum flow of Hydram's Hydrological Station was 4700 cubic meters per second, and the corresponding water level was 30.60 meters. During the flood of last year, the maximum traffic was 5270 cubic meters per second, and the corresponding water level was 29.29 meters. "Increased 570 flows, but the water level dropped by nearly 1.31 meters, which once again confirmed that the ability of the main river tank overcurrent has increased significantly."

According to relevant data, over the past 20 years, through the continuous development of the Yellow River water adjustment and sand, the main slot of the main slot of the river in the lower reaches of the Yellow River has been preliminarily curbed, and the average height at the bottom of the river has decreased by 2.6 meters. According to the forecast, this year, there are more precipitation in the Yellow River Basin, and the flood prevention situation is still severe. The river affairs departments at all levels in the province have greeted their fists and greeted a more difficult test at any time.
