According to the geological disaster warning jointly issued by the Provincial Meteorological Bureau and the Provincial Department of Natural Resources, from 20:00 on June 22 to 20:00 on June 23, Hefei City, Chaohu City, Feixi County , Feidong County , Lujiang County The geological disaster warning level is yellow, and you need to pay attention to precautions.
Heavy rainfall in recent days has put great pressure on Hefei's urban drainage, rivers, lakes and reservoirs.
Relevant departments have acted quickly and actively responded.
Let’s first take a look at the measures taken in urban drainage.
Our city has accelerated the improvement of waterlogging points.
The improvement of a number of "old and difficult" water accumulation points has shown remarkable results.
The reporter learned that in this round of heavy rainfall, some "old and difficult" waterlogging points in the past have been affected. "The water accumulation points have withstood the test this time. At the same time, our city is accelerating the improvement of waterlogging points to solve the problem of accumulated waterlogging.
html It rained heavily on the morning of June 15, and water accumulated at the excavation site near Huachong Park on Changjiang East Road. The Municipal Municipal Affairs Office urgently contacted the Municipal Drainage Office for assistance and called a pump truck to pump out the water. The picture shows workers arranging drainage hoses to speed up drainage. Photographed by reporter Guo Ruqi What used to be a "long-standing problem" is surprising
The section in front of the Mingguang Road Bus Station used to be choked with water during heavy rains, but in the several heavy rainfalls since the flood season, the area has taken on a different look. "In the past, when there was heavy rain every summer, water up to more than ten centimeters deep would form here. Pedestrians had to wade through the water when traveling, which was very inconvenient. But the recent heavy rains have not had the slightest impact on this place." Mr. Wu, a citizen, said.
"The main reason for the accumulation of water in this section is the insufficient water collection capacity of the side vertical water collection wells." Hu Xiao, director of the Municipal Maintenance and Management Office of Yaohai District, told reporters that in April this year, Yaohai District combined with the Mingguang Road quality maintenance and improvement project to transform Mingguang Road All vertical water collection wells on the road (from Shengli Road to Yuxi Road) were replaced with flat grate-type water collection wells, 240 water collection wells were newly built or renovated, and the diseased pipe network was repaired at the same time. This work was completed before the flood season.
"Surprise" also appeared at the intersection of Guangde Road and Leshui Road. "Each of the two roads originally had a rainwater box culvert, which was connected by a pipe in the middle. The diameter of the pipe was much smaller than that of the box culvert, resulting in insufficient passing capacity. When encountering short-term heavy rainfall, water accumulation would form." Hu Xiao introduced , the two box culverts have been successfully connected through construction, and the drainage section has been increased, which has greatly improved the water flow capacity and the original waterlogging points no longer exist.
In addition, the flood-prone spots such as Anhui Jianzhu University North District and Changjiang West Road Anti-aircraft Regiment, which have attracted much attention, are relatively normal during this year's flood season.
htmlOn June 15, at the intersection of Fanhua Avenue and Liaoning Road, a waterlogging point in the city, Baohe District municipal staff were using high-pressure water cannons to carry out desilting and dredging in the rain. Photo by reporter Du Jing Su Ling The renovation of 12 waterlogging spots will be completed before the end of the year
In accordance with the waterlogging prevention and control standards of "effectively coping with the 24-hour design rainstorm that occurs once in 50 years, and the flood control standard is once in 100 years in the central city", the city's flood-prone spots have never been renovated Pause, in addition to the waterlogging point on Mingguang Road that has been renovated, the construction of 14 waterlogging points in the city is currently being accelerated.
html On the morning of June 19, within the enclosure of the intersection of Furong Road and Feicui Road, road waterlogged spots were under construction in an orderly manner. The construction scope of the project is from Chuangye Park Road to Cuiwei Road, a total of 2 kilometers. It mainly involves upgrading rainwater pipes and box culverts to improve their water supply capacity."At present, except for the 100-meter railway section that is not under construction, the rest is basically completed." Project leader Wang Shengsen told reporters that the construction of the railway section will be started as soon as possible, and we will strive to have water conditions by the end of August."Of the 14 waterlogging points under construction, 12 will be completed before the end of this year, and the remaining two will be completed before the flood season next year." The relevant person in charge of the Municipal Drainage Office said that currently, in response to the damage caused by this round of heavy rainfall There are many water accumulation spots in the urban area, and the Municipal Drainage Office is coordinating with various counties and districts to investigate the causes of water accumulation. In the later stage, arrangements will be made to formulate remediation plans and programs, and construction will be accelerated so that there will be fewer and fewer waterlogging spots in the city.
Let’s see if the water levels in rivers, lakes and reservoirs are safe.
Our city actively responds to over-alarm floods.
Currently, except for Xihe and Zhaohe, all other rivers and lakes are on alert. Below the water level
Reporters learned from the Water Affairs Bureau that continuous rainfall has caused the water levels of rivers and lakes in Hefei to rise significantly. The Xihe River exceeded the warning water level at 20:30 on June 21, and the Zhaohe River exceeded the warning water level at 6:54 on June 22. . At present, except for Xihe and Zhaohe, all other rivers and lakes are below the warning water level; except for the Feixi County Modun Reservoir, the remaining 2 large and 20 medium-sized reservoirs are operating below the flood limit water level, and 10 The remaining small reservoirs have exceeded the flood limit and are overflowing.
It is understood that our city took action upon hearing the "flood" and deployed quickly to respond to the current flood situation efficiently. After the Mei season on June 10, the Municipal Water Affairs Bureau dispatched the Chaohu Gate, Yuxi Gate, and Xinqiao Gate in advance to fully discharge water, and dispatched the Fenghuang Neck Station twice to drain the Xihe River floods, minimizing the flood control pressure on the Xihe and Zhaohe Rivers. At the same time, our city has strengthened monitoring and early warning and paid close attention to the development of rainwater and flood conditions. The water affairs, meteorology, and hydrology departments strengthened consultation and judgment, shared information in real time, and issued over-alarm flood warnings for Xihe and Zhaohe two days in advance, firmly grasping the initiative in flood prevention.
In response to the over-warning water levels of Xihe and Zhaohe, our city's dispatching Phoenix Neck Station turned on four units at 15:00 on the 21st, with a pumping flow of 160m³/s; at 6:00 on the 22nd, another two units were turned on. Now the six units are operating at full load, and the pumping flow is 160m³/s. Discharge flow 240m³/s. "On the morning of June 22, we sent five working groups to Lujiang, Chaohu, Feixi, Feidong, Changfeng and Tongjiang gate stations to assist in guiding flood prevention work." said the relevant person in charge of the Municipal Water Affairs Bureau.
Warm reminder:
Be sure to pay attention to safety when going out on rainy days!
