Chapter 305 This is the feeling of heartbeat

You don't know anything about Made in Germany.

"Yes." Looking at Chen Kang's reaction, Zhuang Qianding sighed in his heart, but he could understand that, after all, Chen Kang was not a mechanical major, and had never been in the field of high-end machinery manufacturing, so he lacked common sense concepts about German manufacturing. , which is normal.

This time, it was Chen Kang's turn to fall into silence. He opened his mouth and wanted to say something, but he didn't know how to express his emotions.

Because of this batch of German-made equipment, the development time of the Military Industry Bureau's 60mm mortar and Chinese official rifle projects has been shortened from three months and one year to [-] days and [-] days.

What should he say?
do not know.

The power of words seemed too pale at this moment.

"Director, when will this batch of equipment arrive?" The 'shocked' look on Yu Hua's face finally faded, and he asked Chen Kang with his eyes fixed on him.

Chen Kang responded: "Because this batch of equipment is particularly heavy, and the condition of the Yanma road is very poor, if it does not rain, it will take about 7 days, and if it rains, it will take more than 15 days."

Previously, it took 20 days for the prototype unit of Yu’s Seven Towers to arrive at the base area. The main reason was that during that time, it rained continuously for several days, and the road was muddy and slippery, making it very difficult to transport.

If this situation is put in a wartime situation, they can only choose the old method of the past, destroying the prototype unit Shenjiang, and not leaving it to the enemy.

Hearing this time, Yu Hua nodded. Generally speaking, the time is not too late and can be accepted.

"Director Chen, in view of the problems we are facing now, I think that we should immediately start the construction of Yanma Highway and Yushen Highway, complete the main road between the steel plant - the raw material supply area and the base area - the outside world, use cement roadbed, and use the soil method to burn cement in the early stage. In the later stage, a rotary kiln cement plant will be established to jointly produce cement.”

At this time, Zhuang Qianding said: "I have a complete home-made cement process and a rotary kiln cement production process. There are no technical problems, and it is very mature. The first batch of home-made cement can be produced within three days. Cement, for road construction."

After pre-research before leaving, Professor Zhuang has successfully established a set of rotary kiln cement production process suitable for the overall level of the base. The core equipment is a small rotary kiln and a ball mill. The feeding material is composed of a steel conveyor belt, which can produce ten tons of cement per day. , with an annual output of 650 tons.

This rotary kiln cement plant is small, but the significance lies in solving the problem from scratch.

The local method of firing cement is very simple. A vertical earth kiln is built, powdered limestone and clay are calcined into clinker, and then the clinker, blast furnace slag and gypsum are absorbed into the ink, and the final product is cement.

"I understand that the transportation system of the base area begins with the Yanma Highway and Yushen Highway projects, both of which are under the responsibility of the General Affairs Section, the vertical earth kiln and rotary kiln cement plants are under the responsibility of the Public Works Section, and the Mineral Resources Section must ensure the supply of limestone, clay and gypsum. ." Chen Kang nodded, making it clear.

"About highway construction, I have a suggestion. We can adopt the method of simultaneous construction of multiple lines, and divide Yanma Highway and Yushen Highway into several small sections. Take Yanma Highway as an example, Matouguan to Nanzhuang, Nanzhuang to Tiger. The ditch, Laohugou to Yanchang, and Yancheng are divided into four sections in total, and four construction teams are stationed at the same time, and the construction efficiency has been increased by four times." Yu Hua raised his hand and gave suggestions to everyone.

"Constructing multiple lines at the same time? It's a good way to use this plan." Chen Kang thought carefully, and soon found the benefits of this method, and immediately finalized the road construction plan.

"..."

Zhao Shu and He Yan fell silent when they heard the decision.

This method is good or not. The problem is that the construction efficiency has been increased by four times, which means that the speed of cement consumption and raw material consumption has been increased by four times. As the heads of the Public Works Section and the Mineral Resources Section, the two fell into a headache state. Involuntarily, he looked towards the old continent far away.

The consumption of cement and raw materials is a trivial matter. It is nothing more than building a few more earthen kilns and using a few more explosives to mine. But the most serious problem is...

How to transport?

Noticing the eyes of the two, Lu Yuan could only bite the bullet and look at Chen Kang, reminding: "Sir, our transportation capacity can't keep up. Now all the registered vehicles in the transportation unit are transporting materials and raw materials, and there are no remaining vehicles. To meet the huge gap in transportation capacity for raw material transportation and cement production and supply, calculated based on the consumption of [-] tons of cement per day on two roads... We must have a daily transportation capacity of about [-] tons."

Assuming that the two roads consume a total of 240 tons of cement per day, the use of multi-stage construction means that the consumption will increase to [-] tons. According to the standard of three tons of cement per ton, the total amount of raw material transportation is as high as [-] tons.

But this is not over yet!
The process of transporting raw materials to the earthen kiln requires 240 tons of transportation capacity. After the earthen kiln is fired, it is transported to the construction site again, which requires another 240 tons of transportation capacity, 480 tons per day.

What is this concept?
At present, the daily limit of the General Affairs Office of the Military Industry Bureau is only 100 tons. If it is to meet the construction of two roads at the same time, it means that the transportation capacity must be increased by 4.8 times.

Such a huge capacity gap cannot be solved in a few words.

"Five hundred tons of transport capacity..." Chen Kang frowned slightly when he heard these words, but he did not open his mouth and asked the General Affairs Section to get vehicles, because there are basically no vehicles available in the base area.

In order to raise the current daily transport capacity of [-] tons, the base area has basically been emptied, and all the carriages, ox carts, donkey carts and automobiles are all used. Even the Red Army has no vehicles available. The construction tasks of the production plan.

To make [-] tons...

Where to get so many vehicles?

The meeting room suddenly fell silent, and everyone understood what this situation meant.

"Don't worry everyone. Regarding transportation, I have developed a tractor with a standard load of about 10 tons and an overload limit of 12 tons. This is the design drawing of a [-]-horse tractor." At this moment, Yu Hua appeared again. With a sound, he stood up, took out the design drawings of the classic tractor he carried with him, and placed them on the surface of the long table, signaling for everyone to circulate them.

The standard load is three tons, and the overload limit is ten tons?
As soon as these words came out, everyone present was full of confusion. What kind of tractor can have such a high load capacity?

Without hesitation, Chen Kang immediately picked up the design drawings. In a flash, a power machine with an avant-garde and unique appearance suddenly entered his line of sight.

In an instant, a feeling of electric shock occurred spontaneously, and the electric current passed through his chest and hit his heart.

Pretty.

Simple and beautiful with a mechanical aesthetic.

Seeing this tractor designed by Yu Hua, for some reason, he felt his heart beating very fast, as if he saw a girl with a smile on the corner of his eyes... All his fantasies about love were fulfilled.

No, it fulfilled all his fantasies about tractors.

It's a heartwarming feeling.

"This tractor uses a single-cylinder diesel engine, travels on wheels, and has excellent off-road performance. The maximum speed on cement and hard roads can reach 20 kilometers per hour, and the off-road speed is [-] kilometers per hour. The overall use is very extensive and can be transported Industrial raw materials and civilian materials, and mechanized farming to reclaim barren fields.”

Yu Hua's eyes were bright, revealing an inexplicable look, and he exuded an aura unique to a talented scholar, and slowly introduced: "In addition, it is also widely used in the military field. It can be used as a delivery platform for mortars and anti-aircraft machine guns. Mortars and anti-aircraft machine guns can be fired directly in the carriage, or they can carry an infantry squad for battlefield maneuvering to transport various military supplies. In an emergency, a tractor can be connected in series Can tow three 105mm howitzers for maneuvering retreat."
