Su Dao chose to build the airport at this time, and it was about a thousand kilometers deep behind enemy lines, which really gave the engineers a headache.

Although a brigade of airborne troops was sent to protect them, the feeling of going deep behind enemy lines was obviously different from before, and even if you were watching the artillery fire and working, it would be much better than this.

No one knows when a bullet will suddenly run out and take their own life, so the soldiers are under great pressure to work in this environment.

Furthermore, the project is also very difficult. First, they do not have professional construction equipment. Concrete runways like this have high requirements for various types and must use professional equipment, otherwise various problems will arise.

Although some equipment has been transported, those equipment can only play a certain role and cannot fundamentally solve the problem.

Heavy equipment such as road roller forklifts cannot be transported, so the soldiers are also very confused in this regard.

Second, it is very difficult to dig the runway here. Secondly, the weather is too cold and the concrete cannot solidify at all, and even mixing cement is still a problem.

Building an airport is such a huge project, all the materials need to be airlifted from thousands of kilometers behind, which is absolutely huge.

The load capacity of a transport aircraft is so large. Nearly one hundred times are used for cement, sand and stones alone. In addition, steel bars and equipment, etc., at least two hundred times are required to complete the project.

"Three brother, what should I do? The weather conditions are too bad. I can't start work at all."

A captain held a cigarette in his mouth and an iron pick in his hand. He knocked hard on the ground, responding to his cold echo, even the land had become stronger than bricks.

In this case, there is no possibility of construction at all. In fact, it is not advisable to build a house in winter. Building materials and other buildings are the most fragile in winter. Even if they are well built, the solidification of lime and other things is not good, which can easily lead to house collapse.

Not to mention that the fighter jets weighing dozens of tons have to take off and land. The J-2's requirements for the runway are no worse than the quality of the house, and even more strict than it is.

The take-off distance of J-2 is 400 meters. What is the standard for this airplane? It does not carry any ammunition, and even the cannon shells are not carried. Then only half of the fuel is contained in the mailbox, which is 400 meters.

If fuel and shells are filled with, it will be equipped with a Chinese sword air-to-ground missile. Then its take-off distance is 470 meters. If it is a modified nuclear bomb, the take-off distance will reach about 510 meters to 540 meters.

According to the full load of machine cannon shells and half of the fuel, the distance required for landing is 500 meters, which means that the runway they are about to build must be at least 600 meters, and the width must be between forty and sixty meters.

Of course, this is mainly the runway built for J-2. Other fighter jets will stand aside. Using runways like J-1 is a waste of resources.

And they built the runway. It is naturally impossible that it is only 600 meters long, it must be extended to 1,000 meters or 1,500 meters.

After all, taking off for 470 meters means driving the engine to the maximum, which will damage the fighter itself. Under normal circumstances, no one will do that. Anyway, it is just a longer distance, which is not a big deal.

It is not that the enemy planes have approached the airport and the fighter planes need to be launched as soon as possible. Under normal circumstances, the current situation of the Chinese Empire Air Force Base is generally circular in a radius of three to four thousand meters.

Although there is no runway, it has very good certificates. If the conditions are appropriate, some lawns will be planted. This is also a common practice at the Air Force Airport during World War II.

"Build a house and build the construction site into an indoor place. We will place several more fires inside and use the fires to increase the indoor temperature. You can take people to measure the data first. I will discuss something with Brigade Commander Meng, and then ask the rear to adjust something else."

Huang Dashan thought for a while and said firmly.

It is very difficult and difficult to complete the construction of the airport within one month with the current manpower. This is simply an impossible task. If you want to build it quickly, you must build a house, even simple steel structures or anything else.

They must increase the internal temperature to facilitate the solidification of concrete, otherwise everything will be empty talk.

Soon, Huang Dashan found Meng Dezhu, the commander of the airborne brigade, and explained to him the situation on the engineering side. Although Meng Dezhu felt a little pressure, he had no choice but to focus on the engineering tasks. In desperation, he had to choose to give in and cooperate with the work of the engineer brothers.

In this way, Huang Dashan rowed two regiments from the airborne brigade, and he told them very directly about the arrangements of these two regiments that when they went to the woods to cut trees, the diameter of the trees must be more than 30 centimeters, and the shortest length must be about four meters.

Now the conditions do not allow, and it is not the rear. He does not have so much steel to use. If it is in the rear, he will directly build a steel structure. However, the situation is different now, and the steel behind cannot be transported in large quantities.

After getting through these things, Huang Dashan began to contact the rear, on the one hand, asking for support, hoping that the Engineer Corps would send a squadron battalion to help, and at the same time, the Engineer Corps would also be responsible for the coordination, and they needed a lot of canvas.

Originally, Huang Dashan wanted to use iron sheet, but considering that the iron sheet was inconvenient to transport, it would greatly waste the Air Force's transportation capacity and also cause great inconvenience to their construction.

Moreover, this thing is also disposable. If the iron sheet is removed, it will definitely be thrown here. It is better to ask for canvas directly. The functions are the same, and it is convenient to take it away when you leave.

There is no need for anything that is too warm here. All he needs is to build a large tent that cannot be blown in by the cold wind outside. As for the inside, there is a constant source of fire to generate temperature, as long as it is maintained at a certain temperature.

If it is not good, he can also use two layers of canvas to cover it and keep the cold air outside as much as possible.

In this way, the next day, a battalion of engineer reinforcements arrived at the construction site on a transport plane. The airport was built by Su Dao himself. Although no one knew what to do, no one dared to be careless. No matter how difficult the conditions were, they had to complete it with all their strength.

At the same time, with the command and help of the engineers, the two airborne brigade soldiers in charge of helping placed the chopped sticks in their respective positions as required.

The only thing that is a bit difficult is that it makes people feel embarrassed when digging pits and burying sticks. It took two regiments and half an engineer battalion to complete these tasks in one day, and all of them were spent on digging pits.

As for cutting trees, it didn't waste much time. Two regiments of more than 7,000 people took about half an hour to cut a tree, and it was all done calmly. The soldiers cut down thousands of trees that met the requirements in just one afternoon.

After getting through these things, the sky gradually began to darken. The daytime here didn't last long, so it was normal that it would get dark before work started.

Starting from the third day, the two regiments of airborne troops liberated one regiment, and the remaining regiment continued to help. After another day, a complete shelf was finally set up.

Early in the morning of the fourth day, the canvas that Huang Dashan called for finally came. It took two days for Huang Dashan to command his troops to complete the temporary tent. It should be noted that building a temporary tent here has very high requirements for the top.

Because the snow is very heavy, if the top is not strong, it will cause the tent to collapse.

After the tent was set up, a fire was lit in the tent. Each fire was not large in size, but there were many in number.

Because it is a tent built by canvas, if the fire is too big, it is easy to ignite the canvas. Although canvas is not easily ignited, there are always exceptions for anything.

In this way, the tent that was one thousand meters long and seventy meters wide was filled with thousands of fires for a moment, and the temperature inside the tent instantly increased a lot.

After one night, the earth began to melt slowly, and the ground began to become muddy. Seeing this scene, Huang Dashan finally breathed a sigh of relief. The muddy was not terrible, but the terrible thing was the same as yesterday, no difference.

Seeing this, Huang Dashan no longer hesitated and immediately ordered the troops to start working. For a moment, the brothers from the two engineer battalions began to clean up the soil on the ground, and then a few people teamed up, first pressed back and forth on the cleaned runway with trucks, and drove the ground to the porcelain.

Then, when driving piles manually, because there is no equipment, I can only do this.

Three days later, after seventy-two hours of busyness, soldiers from the two battalions came in rotation, and even the resting airborne brigade was brought to help, and finally the foundation was laid within three days.

Then, sprinkle lime, continue to chase, build a steel net, lay it on the ground, pour concrete, make it porcelain, then place the steel net, and continue to pour concrete. After three repeated trips, the basic project was finally completed, and the surface work did not require so many people to carry out.

Half of the people were responsible for the surface, while the rest began to increase the fire, so that the temperature in the tent could be increased as much as possible.

During this period, you have to sprinkle water continuously, otherwise it will easily crack. Fortunately, the temperature in the house is not low, otherwise where will you sprinkle water on it? It will turn into ice.

In this way, on the last day of the one-month period, the runway was finally built. Next, the temporary tent outside was removed, and the runway at the airport was still usable.
