Chapter 983: Disaster Rescue, Saturation is the Hard Truth
"Don't be anxious, let the expert comrade from the Flood Control Committee finish speaking!" The leaders of the Water Conservancy Department knew from Gao Zhendong's "five-point decision" just now that this comrade might not have such simple ideas.

He is clearly a versatile person who is somewhat familiar with hydraulic engineering, as can be seen from the V-shaped trough and water collection tank he just suggested in his proposal.

"Comrade, please speak." He stopped other comrades and looked at Gao Zhendong.

Gao Zhendong did not hesitate: "My suggestion is to use shaped charge blasting, use strip shaped charge to generate directional metal jet, and use the metal jet to cut as large an opening as possible on the bottom hole inspection gate. This method can be detonated remotely, and it is much safer than manual cutting."

When Gao Zhendong was reading online novels in his previous life, he had seen a similar plot, but it was about blowing up the spillway gate. The method in the book at that time was to ask the army's tanks to shoot with armor-piercing bullets... Gao Zhendong spat out blood when he saw it. The hole where the armor-piercing bullet hit was less than the required flow rate than the urine from prostatitis. Even if the gate was beaten into a honeycomb, it would be useless.

Gao Zhendong drew a picture on the blackboard and explained the principles and uses of linear shaped charges and directional metal jets.

"Ah, I see. If that's the case, it seems that we can indeed use the jet to cut holes, and the shape and size can be controlled."

"Comrade expert, is the principle you mentioned really applicable?"

"It can be used!" Gao Zhendong replied. Just kidding, this kind of jet can even cut off armor-piercing bullet rods.

"How can we ensure that the explosion has no impact on the dam?" The comrades began to show interest.

"I will design a suitable charge shape and try to concentrate the explosive energy in the cutting direction!"

“There’s always going to be aftermath, right?”

"Pre-weld armored steel plates in the 2-meter-long tunnel section behind the bottom hole inspection gate to resist the aftermath. Or directly weld 0.3-meter-long armored steel plates around the strip charge to resist the aftermath. I prefer the latter, which is enough to resist or deflect the aftermath of the explosion, and will not cause the tunnel to be blocked due to the impact of the water flow, reducing the discharge capacity."

Large steel plates may be deformed and stuck due to the impact of water flow, but even if a 0.3-meter long steel plate falls off and is deformed by the impact, it is impossible for it to get stuck on the walls of the tunnel.

"Well... the section of concrete where the inspection gate is located is the thickest, and it is indeed more resistant. But what if the cutting is not continuous? Then there will be almost no chance of another explosion."

"You can weld a tow hook at the appropriate position of the gate, and use a steel cable to apply pre-tension outside the bottom hole outlet before blasting. The pre-tension and water pressure work together to ensure that the incision is opened."

“Why not use frogmen to place explosives on the water-facing side of the gate to blast it?”

"Water is incompressible and is an excellent conductor of blast waves. The impact of an explosion in water on the dam is unpredictable," Gao Zhendong answered quickly.

This is how frying fish works.

After listening to Gao Zhendong's words, the comrades thought about it on their own.

"How do you ensure safety? How do you ensure the blasting effect?" the leader of the water conservancy department asked Gao Zhendong.

Gao Zhendong said: "Before the blast, we will use a steel structure similar to the gate structure to conduct tests to ensure these two aspects. Four days, I estimated, is still enough time."

Although theoretically the dam would overflow in four and a half days, this was a rescue operation in the real world and they couldn't just do it like in a movie where they dismantled the bomb at the last second of the countdown. Gao Zhendong had developed a physiological discomfort with this kind of plot from watching movies in his previous life, so he felt annoyed when he saw the countdown on the "time bomb".

"Okay! Comrade, I will give you the vacant land west of this headquarters. You can directly carry out the work and start the experiment according to your ideas. No matter what the result is, at least get the work done first and start preparation as one of the possible means. We will prepare several methods, and yours is an important one. What do you think?" The leader of the water conservancy department said to Gao Zhendong in a "negotiating" tone.

Gao Zhendong and the blasting expert he brought with him exchanged a glance and said, "Make sure the mission is accomplished!"

"Okay! Comrades, our pyrotechnic expert team is preparing for blasting-related work, and we are not idle either. We will collect as many tarpaulins as possible and cover the main dam with geomembrane, from the front to the back of the dam! This is to keep an extra insurance in case of an emergency. Regardless of whether it can be used or not, at least we are ready first."

Comrades all know that this should be effective when there is no dam overflow, but no one knows how long it will be effective after the dam overflows.

"While we are doing this work, we are also using our brains to think of other solutions. In short, our solutions must be saturated! There must be enough!"

As I said, work is not like making a movie. No matter what the conditions are, it is impossible to rely on a group like the "Fellowship of the Ring" for the success or failure of the entire thing. The tolerance rate is too low.

The good thing about Gao Zhendong's method is that it will not affect the implementation of other plans before the test is completed and the blasting charge is officially installed.

So everyone thinks that having such a guarantee is very good.

Hearing this, Gao Zhendong immediately stood up and called out to the blasting expert who came with him. "Comrade, let's go! Let's get to work!"

After saying that, he turned to the comrades who were still preparing to continue the meeting and said, "If other plans require support in blasting, you can contact us through the radio or come to our test site."

Gao Zhendong then walked out of the headquarters with a few people and said to the other accompanying personnel: "I will draw a few pictures, and you should immediately send them to the Third Rolling Mill of the Seventeenth Machine Department and ask them to process enough copper materials. In addition, notify the fitters above level seven in the Third Rolling Mill, the number of which should be no less than 8 people, to bring as many tools as possible, and transport them here by air along with the copper components!"

Although Gao Zhendong has mastered the experience of shaped charge warheads through designing the warheads of 61 Fire and Red Sword-61, it is still unknown what kind of this kind of charge is most useful. He simply processes several shapes at one time, which can basically cover most possibilities.

The purpose of notifying the fitter to come over is to deal with possible fine-tuning after the test. If there is no machine tool, if you want to rub something by hand, it is more convenient for a fitter than a lathe operator, and the fitter can also operate a lathe.

Gao Zhendong decided to try to rub the blasting charge by hand! Regardless of whether it can be used or not, it is always a good idea to be prepared.

"Yes!"

Gao Zhendong turned to the blaster who came with him and said, "You should also call on the Defense Work Committee to gather a few blasters, and also a batch of black mixed 60, electric detonators, detonating fuses, explosive melting equipment and other equipment to prepare for the test."

"Yes!" As for the specific number of troops to be mobilized, the blasting expert of the unit knew it clearly. There would be more, no less.

As instructions were issued one after another from the dangerous scene, most of the north was busy with this reservoir.

Beijing, Defense Work Committee.

When the Defense Work Committee received the first request from Gao Zhendong, the leader of the Defense Work Committee who was in Beijing raised his eyebrows.

"Wow, Gao Zhendong is really quick! I guess it hasn't been long since we arrived at the site?"

The leaders of the Defense Work Committee were delighted when they saw the list, which had few requirements on varieties but large quantities and very clear special points.

Such details mean that there must be one or several highly targeted plans with relatively optimistic expected effects being implemented.

It is undoubtedly a good thing that the expert group took action so quickly.

As for why he was so sure that Gao Zhendong must have played a role in this, it was nothing more than the matter of the polyurethane spray. Apart from Gao Zhendong, it seemed that no one else among the comrades over there knew about this thing.

"Provide it immediately as required, without delay! Notify the Air Force and mobilize nearby transport planes to stand by at the Beijing Suburban Airport!"

A polyurethane foam spray manufacturer was confused when it received the notice. What was this for? No more foam spray?
However, the words "due to major emergency rescue needs" were clearly visible on the notice from the Defense Work Committee. This was not the time to ask questions, but to speed up production!

"Immediately adjust the process as required. In addition to the comrades on duty, call back all the comrades who can be called back and start production at full capacity!"

At the Beijing suburban airport, several flying tractors are on standby, waiting to transport supplies and personnel.

Around the dangerous area, the motor vehicle regiments of the garrison troops from near to far began to collect tarpaulins as soon as possible, load them onto trucks and transport them to the dangerous area. Even three and a half hours after the notice was issued, the first batch of tarpaulins had been carried to the auxiliary dam by the soldiers, and subsequent tarpaulins were also delivered in an endless stream.

Just when everything was moving, Gao Zhendong's second and third requests came one after another.

"Ah? He really wants to bomb it? Provide it as quickly as possible according to their requirements. Contact the Third Factory of the 17th Ministry of Machine Building. Our planes are on standby at all times. Once they prepare the materials, personnel and equipment, they can fly over immediately." Regardless of whether to bomb it or not, the plan will be approved. It must be a collective decision, so there is nothing to worry about.

Not to mention the Third Rolling Mill, the Third Factory of the Seventeenth Ministry of Machine Building, there is only that place.

The 8th Ministry of Machinery also received the news. The leader of the 12th Ministry of Machinery said, "Notify the Third Rolling Mill, Beijing Steel Mill, and other factories under the th Ministry of Machinery in Beijing. Each factory should provide a few fitters above level , preferably level , and the number should not be less than ... No! . We can't let the burden fall on the Third Rolling Mill alone."

At the same time, the Changjian Machinery Factory received a notice from the Defense Work Committee at the first opportunity and mobilized a batch of their black mixed 60 explosives, as well as electric detonators and detonating wires, and dismantled and transported at least one set of explosive melting equipment from the production workshop. Together with the operators, they immediately rushed to the Beijing suburban airport and flew to the mission target. Even the comrades at the Changjian Machinery Factory did not know where the mission target was.

The reason for transferring to Changjian Factory is that they can arrive at the scene the fastest, and they have all the materials, equipment and personnel.

Fortunately, the explosives melting equipment is relatively not too troublesome and not that sophisticated, so it can be disassembled and assembled quickly.
