Chapter 986 is in full swing
The comrades and excavators who had been on high alert for a long time quickly moved together. The people were responsible for connecting the soil, while the excavators were responsible for covering the soil and compacting it.

This is only a part of it. The current quantity is not enough to completely cover the dam, but judging from the material supply and time, there is no problem in completing it before the planned time.

A comrade behind me shouted into the intercom: "There is enough tarpaulin at the auxiliary dam. Please inform the comrades in charge of transportation at the intersection and transfer it directly to the main dam."

A voice came from the other side: "Understood."

It seems that the comrades in the army provided support very quickly, and the overall volume of the auxiliary dam is relatively small, so the materials are sufficient.

Gao Zhendong left the comrades from the electronic laboratory of the Third Factory to Engineer Luo, and took Fang Yinghong back to the main dam test site. It took more than three hours to go back and forth.

As soon as I got off the car, Yi Zhonghai and colleagues from the Changjian Factory came to meet me: "Chief Engineer Gao, the first batch of charges has been assembled. There are four types, two of each type. We are now welding protective plates on the steel components of the simulated gate."

It seems that everyone is working very quickly. Gao Zhendong took a look at the steel plates being welded. The masters are very experienced in this area. The guard plate has an inward tilt angle, and then an end plate is added at each end of the guard plate to connect the guard plate and the simulated gate together, which further enhances the structural strength of the guard plate. The welding is very beautiful, and it can be seen at first glance that it is the work of a senior welder.

"Mr. Gao, this is our test plan. Please take a look and sign it." The blaster came up with a piece of paper in his hand.

The meaning is very clear. If you think it's okay, you can leave and don't hang around here.

Gao Zhendong knew that this matter could not be discussed. Even though his system was extremely powerful, he was still inferior to the comrades here. There is strength in numbers.

He looked it over carefully, found nothing wrong, and signed it.

The demolition man took over the test plan and nodded to several comrades beside him.

"Chief Engineer Gao, you should go and have some rest. It's already midnight and you haven't rested yet." His tone sounded like a negotiation, but his actions didn't seem like it.

"Okay, I'll go take a rest. Remember to notify the headquarters before the blast test, so that they have enough time to notify other comrades, otherwise the blast will cause misunderstandings. "

"Understood, Mr. Gao."

In the direction of the main dam, obvious lights can be seen and sounds can be heard, which means that other plans are probably being prepared or implemented.

On the main dam, the leader of the water conservancy department was also watching here, and a comrade nearby came up to report.

"Leader, we just received news from the auxiliary dam that the first batch of geomembranes are already under construction. Judging from the material supply and speed, the covering should be completed tomorrow."

"So soon? Okay, okay!"

"The materials received there are enough to complete the geomembrane covering of the auxiliary dam. Now all the materials delivered are being sent to the main dam."

"Well, try to cover the main dam as much as possible. In short, we must try our best to create all conditions so that we can get through this dangerous situation safely." The leaders did not take it lightly just because they had some plans. Even though covering the main dam with geomembrane was the worst-case scenario, they still arranged to carry it out.

Anyway, this incident does not affect the implementation of other plans. The more preparation we have, the more hope we have. Although the people downstream are evacuating, their property and farmland cannot be evacuated.

"By the way, the pyrotechnics expert team just informed us that their first batch of blasting tests will begin in half an hour. Please inform our comrades not to worry."

"Haha, they acted very quickly and thought it through very carefully. They were afraid that the explosion would cause comrades to misunderstand and panic. Okay, you send someone to notify the comrades who are working on the main dam." The leader was very happy. At least the implementation of multiple plans was going smoothly. The main dam relied on the wave-breaking wall, and the main plan of temporarily raising the height was also successfully implemented thanks to the efforts of the comrades.

Their main plan is to pile up sandbags behind the wave-breaking wall to raise the main dam and the auxiliary dam as much as possible, and directly cover them with geomembranes to enhance the anti-seepage performance. At the same time, geomembranes are used to form drainage channels behind the raised parts to divert water to the dam shoulders and then drain them away. Since the problem of water seepage in the auxiliary dam is expected to be solved, there is hope to temporarily raise the dam body on this basis, otherwise it will be useless.

Time passed by minute by minute. Half an hour later, bursts of explosions were heard from the blasting test site. The comrades had already received the notification, but did nothing and were still busy with their work.

Gao Zhendong, who had been dozing off in the tent for a while, was awakened by the explosion. He walked out of the tent and headed towards the test site.

"how is the situation?"

"The test was quite successful. Two types of explosives had very good blasting effects. However, the amount of explosives was a bit too large and the protective plate was blown away. Should we reduce the amount of explosives?" After saying that, the blaster handed over a test record.

Gao Zhendong took the experimental records and walked to the simulated gates to look at them for a while.

"No, the reduced charge may not be powerful enough. This steel structure is hollow but has a reinforced structure. The steel has good performance and is not very friendly to shaped charge armor. We must consider cutting off all the reinforced structure. Wait for me to calculate. Have the follow-up components and other comrades arrived now?"

"Not yet, but Beijing has informed us that they are already on the plane."

Gao Zhendong nodded when he heard it. That would be very quick. Even though the road for transporting materials is not smooth now, it would take at most 5 hours, which means it would definitely arrive tomorrow morning.

Gao Zhendong returned to the tent with the experimental records.

Other comrades are processing other things that may be used here, such as steel hooks welded on the gate to apply pre-tension, as well as fasteners, connectors and other materials for steel cables.

Designing a new design and improving the existing design based on experimental results, the latter took Gao Zhendong a relatively longer time. Several comrades were guarding the four corners of the tent. In the tent were Gao Zhendong who was working hard on calculations and Fang Yinghong who was making osmometers and soil moisture sensors. After more than an hour, Gao Zhendong came out with a new drawing. He greeted several fitters.

"Take kit number two and modify it according to this requirement. Make at least three sets and then test it again."

Three eighth-level fitters from the Third Rolling Mill, led by Yi Zhonghai, took the drawings and started working.

This was a meticulous job that took several hours, and I finally finished the revision in the morning.

After Gao Zhendong and his team had measured all the metal structure kits, Gao Zhendong asked the three fitters to take a rest first. If everything went well, they would still have to work hard.

Comrades from the Changjian Factory rushed over and began assembling and casting.

At this moment, a burst of joyful shouts came from behind.

"Chief Engineer Gao! Chief Engineer Gao!"

He turned around and saw that the person coming behind him was Deputy Director Fan of the Beijing Iron and Steel Plant, followed by a group of workers and a lot of materials.

"Hey, Deputy Director Fan, why are you here?" Gao Zhendong turned around and greeted him.

"Haha, disaster rescue is everyone's responsibility. You can't be the only one doing it." Deputy Director Fan joked.

Gao Zhendong apologized with a smile, and Deputy Director Fan said with a smile: "According to your request, the department has mobilized 9 more eighth-level fitters from the subordinate factories in Beijing. Together with the three who came from your factory, there are a total of people. I have also brought you the components processed by your factory."

Gao Zhendong was very happy. It was true that there was strength in numbers. There was more than one bottom hole and six gates. If it was really successful, the amount of cutting charges that needed to be processed would be considerable.

"Great! We are currently testing the blasting effect of the charge. After this test, we can start adjusting the components."

Although they had just arrived and didn’t know the origin and process of Gao Zhendong’s words, the comrades were all very happy. It seemed that they would be put to good use soon!

More than two hours later, around noon, after three explosions, the comrades surrounded them.

The three simulated gates are similar, with neat cuts, cut off at the roots and almost no adhesion. The shape of the protective plates is basically intact, and they can withstand the shock wave of the explosion very well.

"Chief Engineer Gao, is it okay?" said the blaster.

Gao Zhendong nodded: "No problem, notify the comrades to modify the components and make cutting charges immediately according to the revised drawings."

Send the drawings back and then send them back after they are made. That is the backup plan. It has to be done, but there may not be enough time. The main thing still depends on the fitters on site.

"Comrades, let's get to work!" Deputy Director Fan was very excited. What a grand scene, what a grand scene.

On the main dam, the leader of the water conservancy department poured a portion of self-heating food from a plastic bag into a lunch box and asked while eating.

"How is the situation now?"

"The auxiliary dam has been covered by 70%, and now we are covering the special sensor area and the water collection pool area. These parts need to be covered with steel plates to ensure that the geomembrane does not sink under water pressure. It should be completed before tonight. The rest is to make the dam as high as possible."

"The others?"

"The breach is being plugged and progress is going smoothly. The main dam is installing the testing equipment provided by the pyrotechnics expert team and it is expected to be completed in the afternoon. At the same time, geomembranes are also being made in preparation for raising the dam body and covering the backwater surface behind the dam."

The main dam is much larger than the auxiliary dam. Fortunately, the anti-seepage construction of the main dam has been completed. The main parts that need to be covered with anti-seepage measures are the temporarily raised part of the dam top and the back water surface behind the dam.

The leader did not react much to the pyrotechnic team's installation of sensors, which may be a preparation before the blast.

"So how's the preparation for the explosion going?"

"It's going very smoothly. The pyrotechnics expert team reported that they have recently found the best method for making explosive charges and are now working overtime to make the explosive packs."

His secretary reported that, for the secretary comrade, "cutting charge" was a bit difficult to pronounce, while "explosive package" was easier to pronounce.

"Well, I hope I don't have to use them."

Explosives still sound scary. I hope I don't have to use them.
