Tu Changwang: "The result calculated by Shanghai. The rainfall in the upper reaches of Zhengzhou has weakened significantly. According to the weather forecast, there will be no heavy rainfall in the next week. Tomorrow is the moment of decisive victory."
……
"After the irrigation canals of Qinchang are reinforced, our only weak point is the section from Sunkou to Aishan. If we keep this section, the flood detention area of Dongping Lake will not be used. This will save nearly 200 million mu of arable land," said Huang Huayun Said, "The reserve team goes to Sunkou."
Kaifeng, Henan.
1500 commanders and fighters from the Third Regiment of the First Division of the Chinese People's Liberation Army Airborne Forces arrived in Sunkou on more than a hundred trucks.
This is the first airborne unit of the People's Liberation Army established in 1950, which was then called the First Brigade of the Air Force Marine Corps. In 1958, the First Division was breaking up and merging with the 15th Army to establish the first airborne army of the People's Liberation Army. Only the Third Regiment of the First Division remained in Kaifeng.
The floodwaters of the Yellow River embankment from Sunkou to Aishan have risen to less than one meter from the embankment.This is a flood peak of 21000 cubic meters per second, and there will be even bigger ones tomorrow.To be on the safe side, this section of the embankment must be reinforced again.
"These are the 20 worst trucks in our regiment." Regiment leader Fu Liming pointed to a row of dilapidated American-made trucks behind him. "Time is too tight, so let them play their final role. Load gravel bags on the trucks."
Chapter 186, Fourteen Not Easy Days
On July 7, the Yellow River flood peak of 18 cubic meters per second was measured at Huayuankou, which was 22300 the previous day.
In front of the commanders and fighters of the 20th Division of the 59th Army, the Yellow River looked like a ferocious dragon. The water level was close to the top of the Huayuankou Levee, which was temporarily raised yesterday.
On July 7, a part of the Huayuankou embankment subsided. It should be that the embankment was not firm enough when repairing the embankment in the past few decades. Some 17-meter-long embankments sank by 0.5 to 1 meter.
With an order from the Flood Control Headquarters, the 59th Division and local soldiers and civilians transported 5 tons of soil sacks and gravel to the levee within 22000 hours. Re-fortified again.
At noon on the 18th, there was another summer shower in Zhengzhou. Although it lasted less than half an hour and the water level of the Yellow River did not rise significantly, due to the rain and wind, the waves on the shore were much higher.The water level of the Zhengzhou Railway Bridge yesterday was filled with railway steel girders. Today, about [-] to [-] centimeters of steel girders are also soaked in water.
The 3000-meter-long bridge has 2000-meter steel girders just soaked in the water to withstand the impact of the water flow. The wagons that originally pressed the bridge were suspended. Therefore, on the 17th, the railway soldiers and Zhengzhou civilian soldiers moved tens of thousands of them to the bridge. The sacks filled with soil were spread out to press the bridge.
July 7 at 18:6.
"The water level has dropped! The water level at Huayuankou has dropped!"
17日晚23时，花园口水位是海拔94.42米，18日中午12时是94.85米。下午4时水位回落到94.75米，下午6时是94.60米。
According to the weather forecast, the flood peak on the 18th was the maximum of the Yellow River flood. This flood peak passed Huayuankou safely, which proves that the safety of the river section from Zhengzhou to Luoyang is guaranteed.
……
7 month 19 day.
In the sky above Dongping-Pingyin-Yanggu, the prime minister's special plane circled here three times, and each time a part of the route flew along the Yellow River.After carefully inspecting the flood control situation in the Shandong section of the Yellow River, the Prime Minister's special plane landed in Jinan.
"Yesterday, the largest flood peak of the Yellow River passed Huayuankou safely, and most of Henan can be said to have survived the flood," the Premier said. You have to watch over it all the way until you send this plague god into the Bohai Sea."
Zhao Jianming: "Our province mobilized 75 cadres, workers, and farmers. With the assistance of the 26th Army and the provincial military region, we reinforced the embankment of the Yellow River in the province and inspected the embankment of the Dongping Lake flood detention area. The masses in the second flood detention area have been evacuated in advance, and the provincial military region has planted explosives on the lake embankment directly opposite the second flood detention area."
Prime Minister: "Henan Province did not use the flood diversion area of Changyuan County in the end, and saved 200 million mu of arable land and 11 houses there. In the second flood detention area of Dongping Lake, the area of arable land and the number of houses are more than those of Changyuan County. The opinion of the central government is: Persevere to the end, neither let the floods ravage Shandong, but also protect the livelihood of Dongping County in the coming year."
……
Dongping Lake used to be a part of Liangshan Lake, and the northern section connected to the Yellow River at Chenshankou.When the Yellow River floods, the water from the Yellow River can flow back into Dongping Lake to store part of the flood and reduce the pressure on the Yellow River.
In addition to the water storage capacity of Dongping Lake, after the founding of the People's Republic of China, after the founding of the People's Republic of China, a large area of lowland was designated as the second flood detention area after the founding of the People's Republic of China. A part of the Yellow River flood is stored in the flood discharge area.
But... this large area of lowland is almost the main farming area of Dongping County, Shandong Province.
In the original history, in 1958, the flood of the Yellow River came too quickly. In order to protect the downstream Jinan and Binzhou, the embankment had to be blown up, and the second flood discharge area of Dongping Lake was opened. Then, in 1959, Dongping County was withdrawn and became a part of Pingyin County. .
Because it was the essence of Dongping County that was submerged by the flood, all of it was flooded at once. In the next few years, tens of thousands of people lived on state relief food and took refuge in the houses provided by them in the neighboring Pingyin County. Merge into Pingyin County forget it.

Dongming County, Gaocun Hydrological Station.
"62 meters! God, is this crazy?" The duty officer at the hydrological station finally saw the water level clearly, and was so frightened that he was still yelling when he returned to the house, "It's far worse than this in the 22nd year of the Republic of China!"
"Old Li, you were here in 1933?"
"Of course, I'm in Gaocun. You don't need to look at the instruments. The flood in 33 only went there." Lao Li pointed to a small slope by the Yellow River as a reference. "How much bigger is the flood this year than that?"
"It seems to be about the same as in 33, but why did the water level rise so high?"
……
"The Gaocun hydrological station reported last night that the water level reached 62.8 meters, an unprecedented figure," the Shandong River Affairs Bureau of the Yellow River Committee reported to the prime minister. "The water volume and peak flow of the Yellow River this year are similar to the 1933 flood that has been recorded in hydrology. , but in the past years, the flood would not reach Gaocun, Dongming County, and there would be a breach, so Gaocun has never seen such a high water level."
Prime Minister: "Today is July 7. This flood peak will flow in Shandong for several days, and enter Bohai Sea on the 21th and 27th. This week is a critical time to test you."
Zhao Jianming: "Shengli Oilfield has just reported to us that the Yellow River near the oilfield area has been strengthened and raised. The oilfield workers are driving all the cars and construction machinery available to participate in the reinforcement and heightening of the section from Zhanggai to Binzhou. Under construction."
"The section of the Liaocheng River under the charge of the 26th Army has been heightened and reinforced according to the maximum flood peak volume, and is currently working with the local military and civilians to strictly guard against the Yellow River embankment."
The map of Shandong Province in front of the prime minister looked like a big battle was going on. Small flags were planted along the Yellow River, some representing the field army, some representing the troops of the provincial military region, and some representing the militia and mobilized workers and peasants.
The main force from Lankao in Henan to Liaocheng is the 26th Army. From Liaocheng to Jinan is the Shandong Provincial Military Region. From Jinan to Binzhou is an anti-aircraft artillery division and hundreds of soldiers sent by the Air Force Surface-to-Air Missile Brigade. From Binzhou to the mouth of the Yellow River is the Shengli Oilfield. Staff and Binzhou reserve division.
With the army as the main backbone, 75 cadres, workers, and farmers in Shandong launched a crowd tactic against the Yellow River, which was to lock the Yellow River in the river and let it flow out to sea obediently.
……
Zhengzhou.
On July 7th and 19th, the volume of water flowing through Huayuankou continued to decline. By July 20st, it was already 21 cubic meters per second. Although it was still several times the usual volume of the Yellow River, since the Yellow River embankment has overcome the 19700-meter flood peak, within a few 22000 Under the strict defense of tens of thousands of people, the weakening torrent of the Yellow River is no longer a major problem in Henan.
"Chairman, you are on the edge of the Yellow River, and I am also on the edge of the Yellow River. The levee of the Yellow River in Jixi is 3000 meters ahead of me, and Jinan City is behind me."
The Prime Minister answered the phone call from Jinan to the Zhengzhou Chairman's train.
"The decisive battle against the flood of the Yellow River has now completed the first stage," said the chairman. "The second stage will depend on your battlefield in Shandong."
Prime Minister: "The comrades in Shandong have already exchanged fire with the enemy's vanguard. We stopped the enemy at Dongping Lake, but the main decisive battle is yet to come."
……
Sunkou Yellow River Embankment.
Calculated by time, the current flood peak passing through Sunkou is the one passing through Huayuankou on July 7.
As the Yellow River goes downstream, the water volume will increase, but the course of the Yellow River will also become slightly wider.However, there are always some river sections that are not much wider than the Henan section. These river sections are the time when the firmness and passing capacity of the Yellow River embankment are most tested.
There is a concave shallow U-shaped section here, which means that the water of the Yellow River will violently hit the levee here. When the big flood peak passes by, the dam is most likely to break.
Twenty old trucks belonging to the Third Regiment of the First Airborne Division sank here.The trucks loaded with gravel drove into the Yellow River, and they were strung together with steel cables to prevent one or two of them from being washed away. This added another barrier to the inside of the embankment to prevent the impact of water flow.
The embankment was full of paratroopers and militia fighters, and everyone kept their shovels in their hands, watching vigilantly as the waves of the Yellow River slapped the array of cars.
Dongping Lake and Chenshan Pass.
When the flood peak passed through Chenshankou on July 7, the sluice was opened, and the water of the Yellow River flowed back into Dongping Lake along the mouth.
