Rebirth 1990: I have three golden fingers

The full name of ground pump is "concrete ground pump". It is very rare in China. It is normal that we have never seen it in Luhai and Dahai.

Fang Bai explained to Lu Dahai while pointing with both hands: "Is this ground pump? It is a construction equipment that relies on pressure to transport concrete through pipelines. It can transport concrete up to a vertical height of hundreds of meters. It can transport dozens of cubic meters of concrete an hour, instead of It is too inefficient to use dump trucks to load the goods one by one and then use derrick hoists to send them up.

The inner diameter of this pipe is about ten centimeters, and there is no problem in transporting stones under 50 mm, but the proportion cannot be too large. "

Lu Dahai shook his head and said with a flattering smile: "Mr. Fang, I have never seen the equipment you mentioned. If there is, it would be very convenient. Transporting dozens of cubic meters of concrete in an hour is a bit exaggerated. We are now pulling one cubic meter of concrete." Four or five dump trucks are needed, and a single derrick hoist cannot transport 15 cubic meters of concrete an hour."

Fang Bai was silent. Ordinary concrete weighs about 2.2 tons, heavy concrete may weigh 2.5 tons, and light concrete weighs 1.9 tons.

The dump truck used on the construction site can hold about 0.2 cubic meters of concrete, which is about 500 kilograms.

The company's current derrick hoist is equipped with two motors per derrick. One motor is equipped with one elevator position and can be placed into a dump truck, so one motor can only pull one truck.

It is three stories high, and it takes more than a minute for each wheel of the dual motors. It can transport at most one hundred bucket trucks per hour, which is 20 cubic meters of concrete, and can lay about 160 square meters of 12 cm thick double-floor slabs.

The actual situation is not so optimistic. The workers will also be tired, and the concrete mixing may not be able to keep up. A single derrick and two motors cannot pull 20 cubic meters of concrete an hour.

For example, the first phase of the shopping mall has a single-floor area of ​​5,000 square meters. When Lu Dahai poured the floor slabs, they installed two derrick positions. It required 20 to 30 people to work at the same time. About two to three hundred square meters of floor slabs were poured in an hour, and one floor was poured. It takes two or three days.

The higher the floor, the longer the crane travel time and the less efficient it is to pour concrete.

Lu Dahai only told him some details. Fang Bai only needed to think about it. Based on the data he knew, he mentally calculated the general situation in a while. This is the index finger Golden Finger LV4, which increases the power of logical thinking by four times.

If there is a ground pump and a sky pump, such as a ground pump with a power of 70 to 80 kilowatts, it can transport dozens of cubic meters of concrete to a vertical height of tens of meters in one hour, which can save a lot of manpower.

Recently, Fang Bai has been thinking about what engineering equipment Xinghai Machinery Company should build.

He knows that with the rapid development of my country's construction industry in the future, the demand for engineering construction equipment will be very large.

Now, he has a clue, but he needs to do some market research.

"Okay, I'll ask Song Ji and the others if they've seen it before. This kind of equipment already exists abroad."

"Anyway, I have been working for so many years, but I have never seen the kind of equipment you mentioned, Mr. Fang." Lu Dahai was very sure, "If there is such equipment, I think we should buy one. The efficiency of pouring concrete is too low. A dump truck driver would be worn out after a day of pushing."

Fang Bai nodded. This kind of equipment is not cheap. As far as he knows, a concrete pump with dozens of kilowatt-hours will sell for hundreds of thousands of yuan twenty years later.

Industrial equipment is not cheap these days, only raw materials are cheaper, but the price is not much different from that of later generations, and some equipment is more expensive.

If the product has just been developed, the price will be higher.

The only ones that can afford it these days are large construction companies.

Fang Bai chatted with Lu Dahai for a while and asked him to pay attention to construction safety.

Fang Bai found Lin Ping, Song Ji, Li Fugui and others to inquire about the situation of the ground pump, but they all said they had never seen it.

It seems that this equipment is not available yet.

In fact, what Fang Bai doesn’t know much about is that our country began to explore and develop concrete pumps in the 1970s, and introduced technology to start manufacturing concrete pumps in the 1980s. However, in the true sense, domestic concrete pump manufacturing should start from the predecessor of Zhonglian in 1993. The joint company was established.

Shenyi Heavy Industry developed the first large-displacement, high-pressure concrete pump in 1994. This was my country's first towing pump with an independent intellectual property development system. It had an additional mixing function system than the ground pump.

After more than 20 years of development, my country has become the world's largest producer of concrete pumps.

According to relevant data, approximately 3,000 pump trucks and 6,500 tow pumps were sold in 2007.

During the same period, the total output of foreign concrete pumps was only about 12,000 units.

In general, the annual market size of domestic concrete ground pumps, tow pumps and sky pump equipment exceeds 20 billion yuan, and it is very stable.

In terms of development difficulty, the simplest is of course the ground pump, followed by the tow pump, and the most complex is definitely the sky pump. At the same power, the price of the sky pump is more than ten times that of the ground pump.

The price of foreign products is several times that of domestic products.

If you build a building with a height of tens of meters or even hundreds of meters, it is really inconvenient without a concrete pump.

If Fang Bai develops this thing and develops it within a year, then Xinghai Machinery Company will be the first to enter this market.

Relying on the role of his golden finger, the yet-to-be-established Zhonglian and Shenyi cannot compete with Xinghai Machinery Company in terms of product performance. However, how many units they can sell depends on the capabilities of each company.

Maybe, when Shenyi and Zhonglian saw how powerful Xinghai Machinery Company was, it directly changed the R\u0026D trajectories of the two companies.

Fang Bai doesn't know the market situation of concrete pumps yet, but he knows that Shenyi has not yet entered the construction machinery industry, and Zoomlion has not yet been established. If he develops it, it will be the first company in China.

Fang Bai returned to the mall office and saw Qin Shuyu exchanging accounting-related knowledge with the accountant.

After lunch at the mall, Fang Bai took Qin Shuyu to the bookstore to look for information.

Of course, no information was found. Fang Bai felt that if he wanted to find it, he would have to look for it at Shanghai Jiaotong University. It would be best to consult relevant professors and maybe get access to relevant foreign information.

This is the trouble without the Internet. It is very difficult to find technical information.

However, Fangbai has decided to develop a floor pump.

At around four o'clock in the afternoon, Secretary Wu Xingyun called Fang Bai and asked him to go to the county compound tomorrow to discuss industrial land matters.

the next morning,

Fang Bai and his father-in-law came to the county compound conference room to discuss industrial land with county leaders.

The two parties chatted for half an hour and then went to the site to inspect.

At four o'clock in the afternoon, the two sides settled the matter.

The county is selling 50 acres of industrial land at a preferential land price of only 10,000 yuan per mu, which is limited to investment in valve factory construction.

It is located in Wuxing Village along the west Oubei River, about five kilometers away from Xinghai Shopping Mall. Nearly 300 acres of expansion land have been reserved for Jiayu Company. However, if Jiayu Company does not invest within eight years, this vacant land will be lost to the county. Handled independently.

The location chosen by Fangbai is quite good. It has convenient transportation and is right next to the future Sunshine Avenue.

The county will plan an industrial park of two to three thousand acres near Jiayu Company, specifically for investment in valves and other small workshops, to create the industrial characteristics of Yongjia County.

The county plans to sell land in a unified manner, limiting the time for construction and investment. The sooner people move in, the cheaper the land price will be.

After the planning was completed, the county announced that it would prohibit the random construction of industrial workshops and advocated unified relocation to industrial parks. Investment in industry was prohibited on plots of land planned as commercial areas in the future.

Land prices in commercial areas will have to rise.

In fact, since Xinghai Company last purchased residential land, the surrounding land prices have increased significantly, and land transfers have been strictly controlled. I plan to cover it up. I feel that after the Xinghai Shopping Mall is built, the land in Oubei will be large. rise.

Fang Bai and his father-in-law settled the land matter, and his father-in-law was responsible for the subsequent procedures.

On August 8, Fang Bai, his father-in-law and Qin Shuyu went to the industrial and commercial department to change the shares and registration information of Jiayu Company.

Fang Bai transferred the funds to his father-in-law, and used 500,000 yuan to purchase land, and another 1.5 million yuan to build factories, dormitories and office buildings, which were planned to be put into use one year later.

At present, Jiayu Company is profitable, which will be used to invest in equipment in the future.

Fang Bai and his father-in-law discussed the first valve product and planned to start with the most familiar WCB cast steel gate valve and directly develop medium and high pressure valves.

Fang Bai is responsible for the valve design. He is familiar with this industry and does not need to conduct market research at all. He knows the structure and approximate size with his eyes closed.

He used a 6-inch (DN150) 600-pound class (equal to nominal pressure 10Mpa, PN100) gate valve design to practice.

This type of valve is mainly used in temperatures ranging from -29 to 425°C. Its main function is to connect or cut off the medium in the pipeline. The medium must not be too corrosive. The market demand is very large. It is widely used in oil refining equipment and hydropower stations.

As for the ground pump, he has to slowly check the information and strengthen his study. He currently does not have the ability to design it.

After Xinghai Machinery Company recruits designers, it will work with scientific researchers to tackle key problems.
