Anti-flood "Technology artifacts" in 2016

Since entering the floodplain in 2016 , the average precipitation in the country was 5% more than in 1998 , and the heavy rain process was over 6 times. Prime Minister Li Keqiang rushed to the disaster front line look at the deployment of flood control, 30 hours "fought" in Anhui, Hunan, Hubei provincial flood zone 3.

Face of the raging floods, our country already has more than 18 years ago, much stronger ability to flood relief: the rescue workers invested a total of around 610,000 people, more than 30,000 units of machinery and equipment classes, flood control materials consumed 330 million yuan; the central government The special flood control and drought relief subsidy of 1.165 billion yuan was allocated to support local disaster prevention and reduction. The armed police deployed 16,000 troops and used 395 sets of equipment and machinery . The officers and men of the armed police forces and the cadres and the masses from all parts of the country were united in the struggle to create a city, and there were many touching stories emerging.

It is worth mentioning that the disaster-affected areas have concentrated their efforts and deployed scientifically to put various scientific and technological equipment into the fight against floods and have achieved very good results.

Jiangsu: Anti-flood "Military Soldiers" to Assist "Human Defence" with "Technical Defense"

Since June , continuous heavy rainfall has hit Jiangsu provinces. Although the public sentiment was urgent, a group of new technologies and new equipment played an important role in fighting floods and floods in all parts of Jiangsu. They used “technical defense” to assist “human defense” and “technical defense” became a “judgment” for flood prevention and rescue in Jiangsu this year.

In recent years, the Nanjing Municipal Water Conservancy Bureau has invested a lot of funds to build a “smart water” information platform. The mobile clairvoyance monitoring platform and data line project can meet the needs of monitoring, collection, and management of hydrological data, and realize key flood prevention targets for the Yangtze River and other major rivers and lakes. 24-hour all-round monitoring, and real-time data will be uploaded to the back office system.

The key technology for the collection and transmission of information in small and medium-sized reservoirs has been applied to all reservoirs in Jiangning District, and has greatly improved the ability to grasp changes in reservoir water levels.

July 7 In the early hours of the morning, heavy rains hit Nanjing . The Zhonghuamen station of Metro Line 1 was flooded with rainwater and the station lost power. The Nanjing Power Supply Company of the State Grid quickly organized personnel to deploy generator sets, and used mobile water pump vehicles that could generate electricity autonomously and had powerful drainage functions. A new batch of equipment such as amphibious vehicles capable of rescue and rescue could be rushed to the scene to carry out emergency rescues and timely recovery of China. Gate station power supply.

Hubei: Heavy rain strikes, domestic "anti-flood artifact" reappears

In recent days, the heavy rain in Wuhan has led to public transport and the city's internal rampant, which has attracted the attention of the whole society. This heavy rainfall has dropped 560.5 millimeters cumulatively , breaking the maximum amount of weekly continuous precipitation since Wuhan’s own meteorological record, and even surpassing the 1998 continuous weekly precipitation. Xiaomi company donated 550,000 yuan emergency supplies to Wuhan , including LED lights, mobile power and so on. In order to launch aerial photography in flood reports and provide news visualization and intuitive panoramic views, Xiaomi Technology also provided two sets of millet drones to join the flood report group.

July 6 On the day of the Fengtai Port of Taibai Lake in Wuxue City, Hubei Province, 300 soldiers of a certain pontoon bridge brigade of the Central Army fought continuously for more than 20 hours and built a length of 80 meters , a width of 10 meters , and a height of 9 meters. The "anti-flood artifacts" - steel-wood and earth-stone combined dams ensure the safety of people's lives and property. This is a typical example of the successful promotion and inheritance of the "steel-wood, earth-rock-combination dam" plugging technology created by the 27th group army in 1998 .

The homemade “anti-flood artifact” steel-wood-cement combination dam (cofferdam) is a truss made of steel and wood, which is “rooted” on the embankment below the breach, filled with sandbags in the truss space, and filled with earth in the upstream. Forming the ground, the water flow will be gradually blocking the size of the hole when the earth and rock to the collapse of the cofferdam. Ding Liuqian, director of the Institute of Flood Control and Drought Relief at the China Institute of Water Resources and Hydropower Research, said that if the water flow is too large to be completely filled when the water is blocked, it will directly fill up the rush, and the truss “rooting” can support and stabilize the water. Flow, filled with sandbags by the frame structure, the sandbags will not run away. This method is consistent with the characteristics of water flow, more scientific.

Anhui: Water control, "rubber embankment" to help efficient rescue and disaster relief

In the scene of Wuxi rescue in Wangjiang County, Anhui Province, the armed police's hydropower force applied for the first time a new type of professional flood control and rescue equipment - "water-filled rubber embankment". At the scene, the reporter saw that rescue officers and soldiers set up every 6 people and quickly spread rubber bags. The rubber ribs were connected with Velcro strips. After the water valve was connected, the flood water quickly flowed into the rubber bags, wrapped in protective tarpaulins, and subsequently used. The fixed piles fixed the sub-dikes, and in less than 20 minutes, a 12- meter-long , 0.7- meter- high rubber submerged bank that was “water-controlled” was built.

This equipment is also known as "mobile folding wall", the outer layer is a strong wear-resistant high-strength canvas layer, which is a watertight rubber bladder. In the compressed state, it is light and easy to carry, and where there is danger, it can be moved to where it is; when it is used, it can be drawn locally, and the gravity of the water can be used as gravity to contain the breach. The advantages are high speed, high efficiency and reusability. They are not afraid of rushing into the water, which can greatly increase the efficiency of emergency rescue and effectively control the dangers of flooding dams.

Hunan: expert guidance to reduce agricultural disaster losses

In recent days, heavy rainfall caused various degrees of floods in Hunan. In the face of the disaster, the agricultural departments at all levels in Hunan Province strengthened their guidance on classification and responded scientifically and effectively in an effort to reduce the loss of agricultural disasters.

Strengthen monitoring and early warning. Closely strengthen coordination with meteorological, water conservancy, finance, and civil affairs departments, earnestly fulfill their duties, strictly abide by the regulations on flood control and drought relief, and earnestly implement the system of leading classes and 24- hour personnel on-duty. Timely release of weather forecast warning information. Since June , Hunan Provincial Agriculture Commission and the Provincial Meteorological Department have issued more than 40 warning and disaster relief technical information on Hunan Agricultural Information Network and other platforms .

The information in this article comes from the Internet and was reorganized and edited by China Rescue Equipment Network.

Pay close attention to the classification guide. In response to the climatic trend in the flood season, we have actively organized experts in the provincial agricultural industry technology system, and successively formulated technical proposals for disaster prevention and reduction of crops such as rice, citrus, and tea; and issued the “Emergency Notice on Grasping the Post-disaster Production Management Work of Crops”. Effectively implement various technical measures for disaster prevention and reduction. Agricultural departments at all levels in the affected areas organized agricultural experts and technical personnel such as grain and oil, economics, vegetables, soil fertility, plant protection, seeds, agricultural machinery, etc., to enter the village and go to the village to enter the village. They helped farmers to implement relevant technical measures to help farmers to ensure the recovery of agriculture after the disaster. produce.
