You know nothing about Made in Germany.
"Yes." Looking at Chen Kang's reaction, Zhuang Qianding sighed in his heart, but he could understand it. After all, Chen Kang was not a mechanical major, had never been exposed to the field of high-end machinery manufacturing, and lacked common sense concepts about German manufacturing. , this is a normal thing.
This time, it was Chen Kang's turn to fall silent. 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 formal rifle projects was shortened from three months and one year to 15 days and 10 days.
What should he say?
have no idea.
The power of words seems too pale at this moment.
"Director, when will this batch of equipment arrive?" The look of shock on Yu Hua's face finally faded, and he stared at Chen Kang and asked.
Chen Kang responded: "Because this batch of equipment is very heavy and the Yanma Highway is in poor condition, it will take about 7 days if it doesn't rain and more than 15 days if it rains."
It took a full twenty days for Yu's seven-tower prototype unit to arrive at the base. The main reason was that it rained heavily for several days during that period, and the roads were muddy and slippery, making it very difficult to transport.
If this situation were placed in a wartime situation, they could only choose the old method of the past, sinking the prototype unit into the river and destroying it, leaving nothing to the enemy.
Hearing this time, Yu Hua nodded. Generally speaking, it was not too late and it was acceptable.
"Director Chen, in view of the problems we are facing now, I think we should immediately start the construction of Yanma Highway and Yushen Highway, complete the main road from the steel plant to the raw material supply area and base area to the outside world, use cement roadbed, and use earth-fired cement in the early stage. , and later establish a rotary kiln cement plant to jointly produce cement.”
At this time, Zhuang Qianding spoke up and said: "I have a complete local cement firing process and a rotary kiln cement production process here. There are no technical problems and it is very mature. The first batch of local fired cement can be produced within three days." Cement, used in road construction.”
After preliminary research before leaving, Professor Zhuang has successfully established a set of rotary kiln cement production processes suitable for the overall level of the base. With a small rotary kiln and a ball mill as the core equipment, the feed is composed of a steel conveyor belt, and can produce ten tons of cement per day. , with an annual output of 3,650 tons.
This rotary kiln cement plant is small, but its significance lies in solving the problem of making something from scratch.
The earth-fired cement method is very simple. Build a vertical earth kiln, calcine powdered limestone and clay into clinker, and then absorb the clinker with blast furnace slag and gypsum. The final product is cement.
"I understand that the transportation system in the base area starts with the Yanma Highway and Yushen Highway projects, both of which are under the responsibility of the General Affairs Department. The vertical earth kiln and rotary kiln cement plants are under the responsibility of the Public Affairs Department. The Mineral Resources Department must ensure the supply of limestone, clay and gypsum. ." Chen Kang nodded to make it clear.
"As for highway construction, I would like to make a suggestion. We can adopt the method of constructing multiple sections of lines at the same time and divide the Yanma Highway and Yushen Highway into several small sections. Take the Yanma Highway as an example, from Matouguan to Nanzhuang, and from Nanzhuang to Laohu. ditch, Laohugou to Yanchang, Yancheng, divided into four sections in total, and four construction teams were stationed at the same time, and the construction efficiency increased four times." Yu Hua raised his hand and gave suggestions to everyone.
"Constructing multiple sections of lines at the same time? What a good idea, just use this plan." Chen Kang thought carefully and quickly discovered the benefits of this method, and immediately finalized the road construction plan.
"..."
Zhao Shu and He Yan fell silent when they heard the decision.
Whether this method is good or not, the problem is that the construction efficiency has been increased by four times, which means that the cement consumption speed and raw material consumption speed have been increased by four times. As the heads of the Public Works Section and the Mineral Resources Section, the two of them fell into a headache and looked at each other. He couldn't help but look towards Lao Daluyuan.
The consumption of cement and raw materials is a trivial matter. It is nothing more than building a few more kilns and using more explosives to mine. But the most serious problem is...
How to transport?
Sensing the gazes of the two people, Lu Yuan could only look at Chen Kang and reminded: "Chief, our transportation capacity cannot keep up. Now all registered vehicles in the transportation department are transporting supplies 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, based on the two highways consuming twenty tons of cement per day... our daily transportation capacity must reach about 500 tons."
Assuming that the two highways consume a total of 20 tons of cement per day, the use of multi-stage construction means that the consumption increases to 80 tons. According to the standard of one ton of cement and three tons of material, the total amount of raw material transportation is as high as 240 tons.
But it's not over yet!
The transportation of raw materials to the earth kiln requires 240 tons of transportation capacity. After the earth 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?
The current transportation capacity limit of the General Affairs Office of the Military Industry Bureau is only 100 tons per day. If it is to meet the simultaneous multi-section construction of two highways, 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 transportation capacity..." Chen Kang frowned slightly when he heard these words, but he asked the General Affairs Department to get vehicles without opening his mouth, because there are basically no vehicles available in the base area.
In order to raise the current transportation capacity of 100 tons per day, the base area has basically emptied its wealth. All carriages, ox carts, donkey carts, cars and other means of transportation are used. Even the Red Army departments have no vehicles to use, and they all support the war effort. Construction tasks of time production plan.
To produce 500 tons...
Where to get so many vehicles?
The conference room suddenly fell silent, and everyone understood what this situation meant.
"Don't worry, everyone. Regarding transportation issues, I have developed a tractor with a standard load of about three tons and an overload limit of 10 tons. This is the design drawing of a 12-horsepower tractor." At this moment, Yu Hua came out again. He said, he stood up, took out the classic tractor design drawings he carried with him, placed them on the long table, and motioned 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 confused. What kind of tractor can have such a high load capacity?
Chen Kang did not hesitate and immediately picked up the design drawings. In a flash, a power machine with an avant-garde and unique appearance suddenly came into his sight.
In an instant, a feeling of electric shock arose spontaneously, and the electric current passed through the chest and hit the heart directly.
pretty.
Simple and beautiful with mechanical beauty.
Seeing this tractor designed by Yu Hua, for some reason, he felt his heart beat very fast, as if he saw a girl with a smile at the corners of her eyes... it fulfilled all his fantasies about love.
No, it fulfilled all his fantasies about tractors.
This is a heart-pounding feeling.
"This tractor uses a single-cylinder diesel engine and travels on wheels. It has excellent off-road performance. It can reach a maximum speed of 30 kilometers per hour on cement and hard roads, and an off-road speed of 20 kilometers per hour. It has a wide range of uses and can be transported Industrial raw materials and civilian supplies, agricultural mechanization to reclaim wasteland.”
Yu Hua's eyes were bright, revealing an inexplicable look, and exuding the aura of a genius scholar. He slowly introduced: "In addition, it is also widely used in the military field. Its main position is to tow a 105mm howitzer for field maneuvers, and also It can be used as a carrying platform for mortars and anti-aircraft machine guns. The mortars and anti-aircraft machine guns can be fired directly in the carriage, or it can carry an infantry squad for battlefield maneuvers and transport various military supplies. In an emergency, a tractor can be connected in series It can tow three 105mm howitzers for maneuverable retreat."
