Chapter 1383 Infrastructure Maniac

After making up his mind, Jiang Yanhai started to do everything, sooner rather than later, he directly joined the engineering troops and began to enter the interior of the Great Wall, after finding the most suitable nodes, he used the data analysis and scanning program to directly figure out the entire structure, and then Start installing bombs for directed blasting.

At the same time, the engineering troops behind had also arrived, but what Jiang Yanhai didn't expect was that the first thing they blasted was not the section of the frontal defense against Taotie, but the section of the city wall where Jiang Yanhai and the others entered.

That part 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.

All the ammunition was laid out in less than an hour. The reason why the city gate was blown open was because although tanks could come through the city gate, heavy machinery such as construction vehicles, which were necessary, could not enter.

So, be crisp.

With a huge explosion sound of "Boom", the section of the Great Wall where the city tower is located directly collapsed, and the explosion equivalent calculated in advance directly blew the city tower down a section of road about 15 meters wide.

When the city wall was blown down, the following part was directly entered only by large excavators used in mines.

The huge bucket started working directly, and in less than an hour, the 15-meter-wide collapsed section was directly cleared out.

It is too simple to clear the road. Excavators dug away the excess stone, and the bulldozers pushed the remaining parts directly to the side. The road was cleared first, and then processed later.

While the road here was being cleared, there was another loud "boom!", and the frontal Great Wall defending Taotie collapsed again.

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

But this time it was different from the treatment at the city tower, where all the gravel and the like were pushed away to clear the road.

But the front wall, because it didn't think about blasting it at the beginning, has a height from 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 was blasted, the rubble from the directional blasting could make it collapse directly from both sides, and countless rubble blocks directly formed a slope with the ground on both sides.

Of course, these slopes are made of stones of different sizes, so even a tank cannot use this slope to drive up.

But this thing is very simple. The engineering team has updated a lot of new things, especially the materials produced by the combination of different materials in the two worlds, which opened Jiang Yanhai's horizons.

First, the engineering troops directly drove into the ground with thick steel columns on both sides of the slope, and then inserted vertically with steel plates, and the sides of the slope 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. Is he going to pour the gravel directly with cement, and then form an equal slope? I'm afraid it won't be much more 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 proudly.

Jiang Yanhai shrugged his shoulders. He could only watch. He didn't know much about these things. To be honest, he didn't know how many things scientists had tossed out during this time. No wonder the country spared no effort after learning that there was 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 Forbidden Army. Those ordinary soldiers even thought that Jiang Yanhai and the others were gods. How did the machine come here.

"Special-type quick-drying cement, mix No. 2 material!" Following the command of the logistics staff, Jiang Yanhai saw a soldier pouring a bag of white powder into the mixer truck next to the large water conservancy mixer truck in the front row. in.

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

When the nozzle of the concrete pouring truck started pouring cement on the slope formed by the gravel, Jiang Yanhai was stunned for a moment, because the quick-drying cement was very thin, or it was more like a gray-white liquid, this thing... It is estimated that it is not much thicker than water, and it is much thinner than cement anyway.

When it is poured on these crushed stones, because it is a very thin fluid, it can flow directly into the gaps between the stones along those gaps like water, just like this. Drive in, and drive away after releasing the stuff.

The slope closest to the ground soon, these quick-drying cement should have penetrated under the gravel, and spread to the surface of the gravel. After all, they are not water, and there is no problem infiltrating the gaps between the stones.

When the quick-drying cement surpasses the surface of the gravel, the concrete pouring truck will stop pouring the place and let it flow down the slope.

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

15 minutes, it takes 15 minutes from the beginning of mixing in the mixer truck to the concrete. This time is slower than some quick-drying cements, but what surprised Jiang Yanhai is that the liquid with such a high moisture ratio is in a special After the chemical reaction, it freezes directly, just like freezing water into ice.

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

"The strength is about the same as that of some special cements. If it is combined with steel bars, its strength is not as strong as the previous super-strong reinforced concrete buildings, but it is only one level worse, and it is much stronger than ordinary civilian use." The project leader gave Jiang Yanhai an approximate Introduced a bit.

The person in charge of the project did not directly water the 30-meter-wide sloping section, and it was useless. He first watered a slope road with a width of about 6 meters, which was enough for use.

15 minutes is enough time. Several concrete pouring trucks work together. In 2 hours, a 6-meter-wide slope road across the foundation of the Great Wall appeared here.
