Xinhua News Agency, Tianjin, August 9th (Reporter Shao Xiangyun, Liu Weizhen, Huang Jianglin) … … The flood control work in Tianjin is still going on. In the early morning of the 9th, the banks of Daqinghe River, located in Taitou Town, Jinghai District, Tianjin, were busy. Standing at the bridge head of the Revolutionary Bridge across the Daqing River, the water flow was very fast.
As an important flood discharge channel in Haihe River Basin, the water level of Daqing River continues to rise. According to the latest forecast, as of 10: 00 a.m. on the 9th, the water level at the head of Daqinghe River is close to 6 meters, which is close to the peak of flood forecast, and the flood control situation is grim.
What is the situation of river flood discharge and sluice lifting, and is the material supply sufficient? The current situation of flood control and fighting in Tianjin affects many people’s hearts.

Flood situation: the peak value is approaching, so guard with all your strength.
Camouflage clothes were soaked with sweat, and old cloth shoes were covered with mud. Yang Jinshui, director of Tianjin Jinghai Water Affairs Bureau, who had just patrolled the right embankment of Daqing River, hurried back to the front-line headquarters in the scorching sun. Without taking care of eating, he immediately spread out the "three pictures" he carried with him and judged the latest situation on the spot.
Flood control of Daqing River system, water conservancy project in Jinghai area, location of flood storage and detention area … … Yang Jinshu knows every point in the three schematic diagrams by heart.
"Daqinghe River is Tianjin’s flood control ‘ Main battlefield ’ First, while strengthening the dikes, we have also stepped up the inspection and rescue of the rivers. " Yang Jinshui said that in the past few days, the water conservancy department has been engaged in "multi-line operations", and besides providing flood control and engineering technical guidance services, it has also taken into account the water resources dispatching work in the whole region, and it is often too busy to touch the ground.
During the autumn flood in 2021, the highest water level in Taitou section of Daqing River was less than 5 meters; As of 10: 00 a.m. on the 9th, the water level at the Taitou of Daqinghe River was close to 6 meters, which undoubtedly brought great flood discharge pressure to Daqinghe River with a narrow river channel.
Zhang Chongming, a senior engineer of Jinghai Water Affairs Bureau in Tianjin, said that another 300 to 350 million cubic meters of flood water is expected to enter the Dongdian flood storage and detention area in the next seven days. "It is expected that the Taitou section of Daqinghe River will remain at a high water level for 8 to 12 days, and then the flood will slowly drop, which may take about two months to clear up."
In order to ensure the safe discharge of floods into the sea, Tianjin has strictly implemented the four-level inspection mechanism. Thirty-five experts from Tianjin Water Affairs Bureau formed a technical inspection team to disperse the dike site to guide the disposal problems; The Jinghai Water Affairs Bureau sent 17 business backbones to form a mobile inspection team to provide support to the weak section of the dike; Jinghai District and Xiqing District organized more than 200 township street cadres to form a fixed-point inspection team to ensure early warning and disposal of problems as soon as possible; China Anneng Group sent 75 technical backbones to cooperate with fixed-point inspections and provide technical support.
"At present, the emergency rescue team consisting of more than 9,600 people has been assembled in the front line of flood control in Daqing River, and all preparations have been made to deal with sudden dangers and fully guard the safety of Daqing River embankment." Wang Hongfu, deputy director of Tianjin Water Affairs Bureau, said.

Discharged into the sea: encrypted monitoring, guarding An Lan
Daodao Gate is lined up on the river surface. Here is the flood gate of Duliujian River at the junction of Jinghai District and Xiqing District in Tianjin, from which the flood of Daqinghe River is discharged to Duliujian River and then enters the sea.
Zhang Songtao, director of the floodgate management department of Duliujian River, Haihe Downstream Management Bureau of the Marine Affairs Commission of the Ministry of Water Resources, said that the Haihe River basin water system is fan-shaped from south to north, with the characteristics of scattered secondary water system, complex river system, numerous tributaries, short transition zone and short source and rapid flow. Known as the "Three Rivers Lock Key", the flood gate of Duliu River is an important flood control project of Daqinghe River system in the middle of Haihe River Basin, and it is also the first control project of Duliu River, with a design flow of 3,600 cubic meters per second.

"The flood gate discharges the flood of the Daqing River system and flows into the sea through the river alone, which is the urban flood control of Tianjin ‘ Nandamen ’ The geographical location is very important. " Zhang Songtao explained.
As the "gatekeeper" of flood control work, Zhang Songtao not only carries out engineering inspections and equipment maintenance every day, but also coordinates with the upstream and downstream banks and the left and right banks to jointly protect the An Lan in the Haihe River Basin. From the mobile phones on both sides of his pocket, there was a rapid ringing of the phone from time to time. "I have been sticking to the sluice for nearly two weeks, and my mobile phone is like a hotline." He said.
In addition, the management office also undertakes the important responsibilities of water regime monitoring such as water level and flow. "Hydrological monitoring is hard work." Zhang Songtao, for example, said that it often takes more than an hour to carry out a flow test, especially in the hot summer sun. "In order to provide scientific reference for flood control command and dike work, we have recently encrypted the monitoring frequency, grasped the real-time dynamics of the river in time, and guarded the gate."
Although Zhang Songtao, who is sticking to the front line, has hung up a thick black eye, he still looks radiant when talking about flood control work.
"Workers from different river sections and departments are working together for Enron to spend the flood season in Qi Xin." Zhang Songtao said that he believed that by strengthening observation, patrolling dikes, strengthening dikes and other measures, people would surely win the "defense war" of flood control and fighting as soon as possible.
Material guarantee: orderly deployment and sufficient supply.
At the traffic entrance of Taitou Town, Jinghai District, Tianjin, vehicles transporting flaky piles, sand and gravel materials lined up in a long line, bringing batches of flood control materials to the flood area in a busy and orderly manner.
The rapid advancement of front-line work is inseparable from solid and powerful logistics support. Woven bag applied by Taitou Town and folding bed applied by China Anneng Construction Group Co., Ltd. & HELIP; … In the notebook of Zeng Tianrong, the chief of the Disaster Relief Coordination Section of the Jinghai District Emergency Management Bureau in Tianjin, a series of "material accounts" were clearly and accurately recorded.
"The demand for flood control materials is large and the points are widely distributed. In order to improve the operation efficiency, we will work ahead, measure the amount of materials needed at each point in advance, and directly coordinate the transportation capacity to deliver and unload goods point by point, saving the time for redistribution." Zeng Tianrong said.

"Since mid-June, we have been implementing a 24-hour duty system to respond to emergency needs and carry out reserve work at any time." Under the high-intensity work, Wang Zhi, deputy director of Tianjin Jinghai District Emergency Management Bureau, has a hoarse voice. There is no noise on the road, but the office building where the Jinghai District Emergency Management Bureau is located is still brightly lit.
State Grid Tianjin Jinghai Power Supply Co., Ltd. urgently set up wires and diesel generators, and preset 131 lighting lamps and 6 light tower along the Daqinghe dike to ensure the need for emergency rescue operations at night; The Office of Tianjin Disaster Reduction Committee, together with Tianjin Grain and Material Reserve Bureau, allocated a total of 39,410 pieces of disaster relief materials for centralized resettlement sites in various districts, and supported the emergency relocation and resettlement of the affected people in various districts … … In the "rear" of flood control and emergency rescue in Tianjin, many departments have also taken action and joined forces to fight.
"At present, we are doing our best to improve the flood prevention capabilities of the two lines of defense, Daqing River and Ziya River, and combine the inspection of dikes with the plugging of loopholes. At the same time, pre-set emergency materials and equipment in time to facilitate emergency rescue work in the future. " Wang Hongfu said that on the basis of engineering measures, technical means, organizational system, materials and equipment, relevant departments will go all out to do a good job in fighting floods and ensuring the safe discharge of floods into the sea.
