On August 29th, beside the Juanqiao Reservoir, Gong'an County, Jingzhou City, at the junction of the two provinces of Hubei and Hunan, the cool breeze blew its high temperature for many days, and also brought hope to the arid land here.

In recent days, the accumulated 20 mm precipitation has finally allowed the staff of the rolling bridge reservoir for many days to breathe a little. In this "thirsty" summer, through scientific water storage and scheduling, under the premise of ensuring the safety of residents' drinking water, they fight sweat in the rolling bridge reservoir, and through various ways, they ensure that there are a total of three villages around the two provinces around the reservoir. Basic demand for drinking water and agricultural irrigation of more than 70,000 people.

Use the window to grab 2 million cubic meters of drought to resist drought

The Bridge Reservoir, located at the junction of Gong'an County and Hunan County, Hubei, opened in 1959 and was put into use in 1972. The area of ​​the reservoir is 2.53 square kilometers, and the largest library capacity is 12.2 million cubic meters. At present, the capacity of the reservoir is about 4.91 million cubic meters.

This capacity can also be maintained after the drought -resistant and water -resistance for many days, thanks to the scientific water storage in the rainy season.

The current rolling bridge reservoir water level

According to the design, the flood reservoir needs to be reached when the water level reaches 50.7 meters. In previous years, the water level was generally started in the water level and started to release the water to respond to the possible floods. However, this year, according to the results of the previous data calculation, the water conservancy department has made a predictable judgment that may have a large drought. Therefore, when the water level in the rainy season is high, the management station of the rolling bridge reservoir is properly adjusted under the premise of ensuring the safety of the reservoir to the flood. The water storage level is high, and the water storage is 50.5 meters.

It is this extra 0.5 meter that increased the reservoir's library capacity of 2 million cubic meters. This also allowed the reservoir to win valuable library capacity in the later drought resistance.

The staff of the Rolling Bridge Reservoir Management Station told Jimu Journalists that since 2010, the reservoir is mainly used as a source of water water for rural safety, and it has supplied water for the surrounding of the Water Plant in Zhangzhuangpu Town, Zhangzhuang, Zhangzhuang, Hunan Province. Hubei 50,000 people and 20,000 people in Hunan. In order to ensure water supply, the reservoir will only ensure the living water of residents and not providing irrigation water without providing irrigation water. Therefore, this 2 million cubic meters of water from the hands of "grabbing" from God has become a vital Ganquan in the drought resistance.

Excantanize for every drop of water to be practical

Although there are libraries that increased water storage in the early stage, the continuity of the drought still made the rolling bridge reservoir feel the pressure. Since the plum this year, the rolling bridge warehouse is mainly based on high temperature and drought weather. The rainfall is 50 % less than the same period of the year, the average daily temperature is 2.4 ° C, and the high temperature above 35 ° C is 13.8 days higher than the same period.

Affected by the continuous sun and hot and high temperature weather, the rolled bridge reservoir gates and pumping stations around the reservoir area were launched in a timely manner. As of 8:00 on August 26, the water level of the reservoir was 49.06 meters on the day, the reservoir was 4.96 million cubic meters, and the annual cumulative irrigation water volume was 2.407 million cubic meters. The demand for the production of the people in the irrigation district.

"On August 13th, the operation of the operation units continued to run in the later stage, and the Kuqiao Village Danjintai, Moon Mountain Pump Station and Nanzhu Mountain Pump Station continued to start operation, with a daily water supply of 48,400 cubic meters; the weapon pumping station 75KW unit 75KW units Continuous operation, the daily water supply is 25,900 cubic meters; the 30KW unit of Tianhe Pump Station continues to run, and the daily water supply is 08,000 cubic meters. The daily irrigation amount is about 80,000 cubic meters per day. " Calculated by the staff of the Bridge Reservoir Management Station. The purpose of these "mathematics problems" every day is to calculate the daily water accounts as clearly as possible, so as to infer the best way to take care of living water and irrigation water under the drought.

In order to ensure that under the premise of the residents' water supply, it can also take into account irrigation water. On August 14, the water level of the reservoir dropped from 50.33 meters at the beginning of the month to 49.51 meters. In order to respond to the actual situation of drought resistance, the county flood prevention and drought resistance headquarters ordered the closure of the water supply of the reservoir's sluice to supply water, and the reservoir management unit strengthened the surrounding pump station water management and living water monitoring.

The reservoir opens the gates and the water is put into strict approval system. The villages and towns around the reservoir need to be put in water. The area of ​​farmland area, water release time and water that require irrigated farmland should be marked on the water release letter. Each drop of water is used.

In turn, the basic needs of irrigation of the two provinces

Save water is also to fight the "long -lasting war" with drought, leaving as much water as possible for anti -drought and long drought.

On August 24, the pumping station around the reservoir continued to operate for 24 consecutive days, and the water level of the reservoir dropped to 49.11 meters. After coordinating the coordination of the county water conservancy and lake bureau, the Zhangzhuangpu Town government of Gong'an County, and the Fuxing Town Government of Xianxian County, Hunan, it was decided to start with the water random irrigation pump with the water source of Zhangzhuangpu and Fuxing Town from August 25 The station implements a batch of water lifting, and the reservoir management unit urges the village groups to improve the efficiency of water consumption and avoid waste of water resources due to management problems.

According to the staff of the Rolling Bridge Reservoir Management Station, the three villages in the surrounding villages are mainly the surrounding villages. In order to achieve scientific scheduling, after the relevant departments are negotiated, these three villages have implemented a "take turns to sit in the village". Just arrange a village to raise water and formulate a clear "timetable" to maximize the demand for irrigation water for each village. Some citrus shed due to water shortage

Sliminating does not solve all problems. Public Security County is also actively "open source" for the rolling bridge reservoir to find water sources of water replenishment. Through the neighboring Laoshui Reservoir, the water regulation supported the drought resistance and irrigation around the bridge reservoir, and the accumulated water regulating 1.3 million cubic meters of water greatly relieved the pressure of the curly bridge reservoir. At the same time, Jingzhou City also combines artificial rainfall operations. While helping the reservoir to store water, it relieves the drought in the irrigation zone while helping the reservoir to "reduce the burden".

The masses' self -rescue, the safety of the birthplace of the citrus is safe

On August 29th, in Juqiao Village, Zhangzhuangpu Town, Jizhu Journalists visited the impact of continuous drought on this.

The terrain of Juanqiao Village is dominated by hills. After the reservoir was completed, the local area began to try to grow citrus in 1974. After decades, it has become a "golden signboard" of agriculture. As the birthplace of citrus planting in Gong'an County, there are three or four thousand acres of orange gardens, including honey oranges, grapefruit, and New hormones. The continuous drought has also brought a lot of influence on the orange garden.

Citrus tree is facing water shortage

Liu Jingyun, a secretary of Tuqiao Village, introduced to Jimu Journalist that there are two or three thousand acres of water in the existing orange trees. "Even if it rains continuously, it is almost 60 % or more."

He rolled out an orange hanging on the tree, referring to the reporter: "This kind of yellow that has become yellow, we call it solar fruit, which is caused by continuous water shortage and exposure. Basically, no one is willing to acquire. "Liu Jingyun said that because the terrain of Tuqiao Village is dozens of meters higher than that of the reservoir, it is difficult to reach the area where the orange tree is in the area where water is irrigated. The task is already a tree -saving tree.

The amount of water in the weir is close to the dry exhaustion

The villagers are also actively helping themselves. Beside the weir in the village, the villager Ye Minghai was weeding orange trees. Although there is not much water in the weir pond, he is still trying to let the orange tree survive.

By the Jintai Pump Station near the reservoir, the villager Mu Xingfu looked at the three or four hundred acres of orange gardens, with a bit of comfort in his tone: "If there is not the water from the pump station, these trees are afraid of it."

He said that these trees were the first batch of orange trees planted around 1974, and it was the birthplace of the orange tree of Gong'an County. Compared to the newly planted trees, they are more afraid of drought, but through the twice of water adjustment and irrigation on July 12 and August 19th, although some fruits are still falling off, it is expected to be reduced to about 30%, but the trees are all trees. Can be kept.

"The tree is in the coming year," Ye Minghai said.
