Since I Was a Special Soldier

After he made up his mind, Jiang Yanhai started to do everything in a hurry. He immediately joined forces with the engineering troops to enter the interior of the Great Wall. After finding the most suitable node, he used the data analysis and scanning program to directly figure out the entire structure, and then The installation of directional blasting bombs began.

　　 At the same time, the engineering troops behind had also arrived, but Jiang Yanhai did not expect that the first thing they exploded was not the frontal defensive section, but the section of the city wall where Jiang Yanhai and the others came in.

　　 That section of the city wall is very narrow, because it is not the main defensive force, and there are no various organs inside.

　　 So the place where it exploded was where the city gate was.

　　 It took less than an hour to arrange all the ammunition. The reason why the city gates were blasted was because although tanks could be passed through the city gates, there was no way to enter the necessary heavy machinery such as construction vehicles.

　　 So, just a little bit more.

　　 With a huge explosion of "boom", the section of the Great Wall where the castle tower was located collapsed directly. The calculated explosion equivalent directly blasted the castle tower down a section of about 15 meters wide.

　　 When the city wall was blown down, the following part was directly entered by a large excavator that was only used in the mine.

　　 The huge bucket started to work. In less than an hour, the 15-meter-wide collapsed section was directly cleared out.

　　 It was too simple to clear the road. The excess stone was excavated by the excavator, and the remaining few bulldozers were pushed directly aside to clear the road first, and then deal with it later.

　　While waiting for the roads here to be cleared, there was another huge tremor with the sound of "Boom!", defending the gluttonous frontal Great Wall, and a section of the Great Wall about 30 meters wide collapsed again.

　　 Countless fragments flew everywhere, and this section of the Great Wall collapsed completely.

　　 But this time it was different from the treatment in the castle tower, where all the rubble was pushed away and the road was cleared.

　　 But the city wall on the front, because I didn’t think about it being exploded at the beginning, it has a height with the ground on both sides. The foundation itself is built on the ridge, so its foundation is higher than the ground on both sides.

　　 When it is exploded, the gravel from directional blasting can make it collapse directly from both sides, and countless gravel blocks directly form a **** with the ground on both sides.

　　Of course, these slopes are made of different stones, so even tanks cannot use this **** to drive up.

　　 But this thing is very simple. The engineering troops don't know how many new things have been updated, especially the materials that broke out from the combination of different materials in the two worlds, which opened up Jiang Yanhai's horizons.

　　 First, the engineering unit directly used thick steel pillars to drive into the ground on both sides of the inclined plane, and then used steel plates to insert it vertically. The two sides of the inclined plane were immediately completely blocked by the steel plates. Then countless cement trucks and concrete pouring trucks drove over in an instant.

　　 "What are you going to do?" Jiang Yanhai asked curiously, because he didn't know what the other party was going to do, so he poured cement directly on the gravel, and then formed an equal slope? I'm afraid this is not much stable, right?

　　 "New type of quick-drying cement, chief, just look at it." The person in charge of the backward engineering unit raised his eyebrows triumphantly.

　　Jiang Yanhai shrugged his shoulders. He could only look at it. He didn't know this very well. To be honest, he didn't know how much things the scientists had tossed up during this period. No wonder the country has spared no effort after learning that there is a new world, and directly agreed.

Lin Dianshuai and the others were also watching. The power displayed by these huge steel machines once again shocked everyone in the Shadowless Imperial Army. Those ordinary soldiers even thought Jiang Yanhai and the others were gods. Otherwise, these huge How did the machine come here?

"Special type quick-drying cement, mixed with No. 2 material!" Following the command of the logistics staff, Jiang Yanhai saw the large water conservancy mixer at the front. Soldiers poured a bag of white powder directly into the mixer. in.

　　 Then the mixer truck rumbling directly began to mix. About 5 minutes later, the mixer truck and the concrete pouring truck were connected together, and the quick-drying cement was drawn directly from the mixer truck.

When the spout of the concrete pouring truck began to pour cement on the **** formed by the gravel, Jiang Yanhai was stunned, because the quick-drying cement is very thin, or it is more like a gray-white liquid, this thing... It is estimated that it is not much viscous than water, and it is much thinner than cement anyway.

When it is poured on the gravel, because it is a very sparse fluid, it can flow directly into the gaps between the stones through the gaps like water, just like this, a tank of cement is constantly being poured. The drove in ~www.wuxiaspot.com~ after releasing the thing and drove away.

　　The **** closest to the ground soon. These quick-drying cements should have penetrated all under the gravel and have spread to the surface of the gravel. After all, they are not water. There is no problem to seep into the gaps between the stones. It is probably a little bit choking to seep into the soil.

　　 After the quick-drying cement surpasses the surface of the gravel, the concrete pouring truck will not pour the place, allowing it to flow down the slope.

　　 But in the process of flowing down, Jiang Yanhai saw its speed gradually slow down.

15 minutes, the time from when it starts to mix in the mixer to the concrete is 15 minutes. This time is slower than some quick-drying cements. But what makes Jiang Yanhai a little surprised is that the liquid with such a high water content is in a special After the chemical reaction, it is like freezing water directly into ice, and it freezes directly.

　　 "This is our new fast-drying cement. It can penetrate into many fine cracks. Some river sand that has not been screened can penetrate directly, and then solidify in 15 minutes, and its strength is very strong!"

"In terms of strength, it is similar to some special cement. If it is matched with steel bars, its strength is not as strong as the previous super-strength reinforced concrete buildings, but it is only one level behind, much stronger than ordinary civil use." The person in charge of the project gave Jiang Yanhai an idea. Introduce it.

　　 The person in charge of the project did not directly irrigate all the 30-meter-wide **** sections, so they couldn’t use it. They first irrigated a 6-meter-wide **** road, which was enough for use.

　　 15 minutes was enough. Several concrete pouring trucks worked together. In 2 hours, a 6-meter-wide sloped road across the foundation of the Great Wall appeared here.
