The report jointly submitted by the three units was quickly approved by the upper level, and the state really has great determination to promote the development of the equipment manufacturing industry, not only agreeing to the requirement that major risks be borne by the state finance, but also allocating funds to subsidize the first set of insurance business. According to the calculation of the property insurance company, the insurance premium that manufacturing enterprises need to pay for the first set of equipment is equivalent to 10% of the transaction price of the equipment on average, and the state has allocated a special fund from the treasury to subsidize 80% of the insurance premium, so that the premium that manufacturing enterprises need to pay has dropped to only 2% of the transaction price, which is acceptable to all enterprises.

As soon as the first set of insurance policies was introduced, the National Development and Reform Commission immediately issued supporting policies, requiring domestic enterprises to give priority to domestic equipment when bidding for equipment.

As soon as this policy came out, Luo Ye and other manufacturing companies were overjoyed, while some user companies complained. No way, hundreds of years of superstition on imported equipment, not three or five years can be changed, in fact, domestic equipment can only show its own quality in a wide range of applications, in order to win the trust of users. In the past, user companies can use risk as a reason to refuse domestic equipment, but now the country has launched the first set of insurance, because of the use of the first set of domestic equipment caused by the loss, there are insurance companies to provide full compensation, what other reasons can you find out?

Practice has shown that there is such a thing as a reason, as long as you want to find it, you can always find it. On this day, Feng Xiaochen just got home from work, and found that Yang Haifan, general manager of Chenyu Construction Machinery Company, and his younger brother Feng Lingyu were sitting in the courtyard of his house waiting for him.

"Huoyuan Metro tendered, and our company's shield machine failed. Yang Haifan said to Feng Xiaochen.

The shield machine is the main equipment used for the construction of the shield method. The shield method refers to the use of a movable shield shell to protect the working face when carrying out tunnel excavation operations, and to carry out excavation, slag discharge, lining assembly and other work under the shield shell. After completing the operation of one operation section, the shield shell can be advanced to continue the operation of the next operation section. This construction method is safe and efficient, and is widely used in tunnel operations in urban rail transit, railways, highways, municipal infrastructure and other fields. According to the data, the shield method originated in Europe at the earliest, has a history of 200 years, and gradually matured after the 30s of the last century, and has become the preferred technology in tunnel construction nowadays.

The shield machine is the machinery for shield operation, including the shield shell, cutterhead, propulsion system, cutterhead driving device, muck conveying device, segment assembly device and other parts, with a total length of more than 100 meters, equivalent to the length of six or seven train carriages, is a behemoth.

The history of shield construction in China can be traced back to the early 60s of the last century, but the use of shield machines began in the 90s, and the application range is relatively narrow. After entering the new century, the subway construction has been carried out in various places, in order to avoid the destruction of the original ground buildings in the city, the shield method construction has been widely adopted, and the shield machine has been widely valued.

Previously, the shield machine used in the domestic subway construction all came from abroad, and several domestic construction machinery companies have carried out the research and development of the shield machine, but the whole machine has not yet been launched. Chen Yu Construction Machinery Co., Ltd. has carried out the technical research and development of shield machine since the 90s of the last century, and the chief engineer of the project is Feng Lingyu.

Feng Lingyu majored in mechanical manufacturing when he was a graduate student in Germany, and after returning to China, he was arranged by Feng Xiaochen to join Chenyu Company as a technician. After a few years of grinding in the workshop, Yang Haifan transferred Feng Lingyu back to the technical department and asked him to take the lead in a research and development project. Feng Lingyu chose such a difficult project as the shield machine, and from there to the present, he finally achieved fruitful results.

Feng Lingyu's research can be ahead of several large state-owned enterprises, thanks to Chen Yu's investment in the shield machine project, on the one hand, because Feng Lingyu himself is the company's shareholder, and even the successor of the internal designation, on the other hand, the actual controller of the company, Feng Xiaochen, gave a high evaluation of the shield machine project, and instructed Yang Haifan to vigorously support the project.

As a traverser, Feng Xiaochen knows that the current domestic infrastructure is just the beginning, and the scale of infrastructure will be expanded by more than ten times in a few years, so that it will gain the reputation of an "infrastructure madman". In the 20s of the 21st century, there will be hundreds of cities in the country to carry out subway construction at the same time, and the shield machine is an indispensable tool in the construction of the subway, the scale of this market will reach trillions of yuan, Chen Yu company 10 years in advance of the technical reserve of the shield machine, is absolutely right.

Feng Lingyu does not have the management ability of his brother Feng Xiaochen, but he has some strength and resilience in scientific research. When he was studying in Germany, he systematically studied the principle and key technology of the shield machine, and at this time, with the company's full protection in terms of human and financial resources, the results naturally emerged like a blowout.

Chen Yu construction machinery company in excavators, concrete pump trucks and other products to obtain a high market share, the scale of the enterprise has expanded dramatically, is now a large enterprise with assets of more than 10 billion, and has established a wide range of cooperation. In the process of developing the shield machine, Feng Lingyu received the help of a large number of cooperative enterprises, such as grouting system, hydraulic system, automatic guidance system, component sealing system, lubrication system, cooling system and other technical problems, which were easily solved with the help of these cooperative enterprises. Today, Chen Yu Construction Machinery Co., Ltd. has mastered all the key technologies of the shield machine, and there is only one opportunity to practice.

Yang Haifan set his sights on the subway construction project in Huoyuan City, Heyang Province, which was undergoing preliminary preparations, and took Feng Lingyu to sell the Chenyu shield machine. Who would have thought that as soon as they heard their intentions, they blackened their faces and claimed that they had selected the shield machine produced by the German Prometheus company, and the domestic shield machine, but they said that they had not heard of it, did not know, and did not mention it again......

Hearing such a resolute denial of the third company, Feng Lingyu immediately wanted to be anxious with others. Yang Haifan grabbed him quickly, and then discussed with the other party with a humble attitude, hoping that the other party could give him a chance. Yang Haifan also specifically mentioned the first set of policies just launched by the country, claiming that Chen Yu shield machine is also the first set of domestic shield machine, Chen Yu company can apply for national insurance support, the other party in the use of any problems encountered, are able to obtain insurance claims.

"It's not a matter of insurance. Jiang Zhong, the project manager of Heyang Metro Engineering Company, said to Yang Haifan at the wine table, "The use of Promai's shield machine is the words sent by our general manager, do you say that those of us who are working below dare not do it?"

"Why did your general manager recognize Prometheus' shield machine?" Yang Haifan asked in surprise, "Our shield machine happens to be designed based on Prometheus's shield machine, and all the performance is not lower than the level of Prometheus, and there are some innovations in some places, which are better than Prometheus." ”

Jiang Zhong shook his head with a smile and said: "I have also read your information, and it is indeed not much different from the equipment of Promai, and the price is 40% cheaper." To be honest, if I can have the final say, I'd be willing to give your equipment a try, maybe there will be some surprises. But if we disobey, if you want us to use your shield machine, let's go up the upper route. ”

Yang Haifan is not a rookie in the shopping mall, and he is no stranger to such things as going up the upper route. However, when Yang Haifan contacted the office of the subway engineering company and asked to meet with the general manager Han Nanbin, he was closed, and the staff of the office told Yang Haifan that Mr. Han was upright and never accepted any intercession, and Chen Yu's products wanted to be recognized by the subway engineering company, and should participate in the public bidding, and any private visit was redundant.

Yang Haifan participated in the equipment bidding with helplessness, and the result was that the bid was lost without suspense in the case of a great advantage in cost.

"What is the reason?" Feng Xiaochen asked.

Feng Xiaochen knew in advance about the participation of Chenyu shield machine in the bidding of Huoyuan subway project, and he also knew very well about the performance and price of Chenyu shield machine. With his original idea, Chen Yu shield machine to participate in the bidding, there is a great certainty of winning the bid, because the price of imported shield machine is abnormally high, and the service is not timely. In the case that there is no similar equipment to replace in China, imported equipment is naturally the emperor's daughter who does not worry about marrying. However, in the case that similar products have been developed in China, the market competitiveness of imported shield machines will be a question mark.

Of course, listening to Yang Haifan say that Chen Yu failed the bid, Feng Xiaochen did not feel particularly surprised, it is not a day or two that domestic equipment has been discriminated against in the application, and one of the daily work of the equipment company is to help domestic equipment companies go to users to discuss the law.

Yang Haifan said: "There are many reasons for their refusal. For example, they put forward that they want the rated jacking force of the jacking control system to exceed 80,000 kN, and our equipment is 75,000, which is not qualified. ”

"How much is Pumai?" Feng Xiaochen asked.

Feng Lingyu sneered: "81,000." ”

"No wonder, isn't this the clause designed for Prometheus?" Feng Xiaochen said with a smile.

Feng Lingyu said: "Isn't it? Many of their terms are set according to Promai's equipment, Pumai is higher than us, they set it a little higher, and Pumai is lower than us, they ask for a little lower, there is no logic at all." ”

"Behind the absence of logic, there is abundant logic. To put it bluntly, they just don't plan to use domestic equipment, so they will try their best to create a threshold. We've seen too many things like this. Feng Xiaochen said with emotion.
