Since Huaxing Construction Machinery wants to develop a full-section tunnel boring machine, it is also indispensable to master the design and development of devices such as electric spark sources.

The previous domestic research and development of this kind of electric spark source device is from the seventies of the last century began to develop, the land, sea and deep well excited electric spark source have been studied, the nineties developed the largest electric spark source maximum energy of 400,000 joules.

However, the electric spark source equipment developed by these domestic research institutes in the early days of the electrical engineering institute all use arc discharge technology, the discharge switch is a spark gap switch, and the discharge electrode is a single group of electrode pairs, of which the marine electric spark source mostly uses parallel electrode pairs, and the land electric spark source mostly uses coaxial electrode pairs.

The appearance of these devices only solves the problem of whether the device is or not, but the device is very large, the stability of the device is poor, and especially the user experience is very poor.

The foreign products began to use pulse corona technology in the first ten years, and the discharge switch abandoned the spark gap switch in the original arc discharge, and used high-power thyristors and multi-electrode emission arrays as discharge electrodes, the products can be made very small and convenient, and the electrode life is also very long.

Since Huaxing Group has mastered the technology of high-power semiconductor devices, many domestic research institutes have begun to use these devices to develop spark source equipment for pulse corona technology schemes.

The technical strength of domestic research institutes is not inferior to that of foreign companies, but the domestic industrial design and process level are really not complimentary.

Over the years, Huaxing Group has been developing arc engines, and its technical strength in this regard is also first-class, and it also has a large number of technical patents in its hands, but it has not been involved in geological exploration before.

This time, Huaxing Group also introduced technology patents and processing software and algorithm models in software to domestic research institutes in this area.

Huaxing Group is also convening a technical team in this area to start developing equipment in this area on the introduction of technology patents.

When Mao Tsuka Tehiko and others talked to Yang Jie, they also noticed that the big boss had really made a lot of technical preparations in this regard, and he was very determined.

Since the big boss is determined to develop a full-section tunnel boring machine, and says that he wants resources to give resources, they are also relieved.

At this time, Mao Tsuka Tehiko also knew that his big boss wanted to independently develop a full-section tunnel boring machine, and after he joined Huaxing Construction Machinery Company, he also knew that the soul of Huaxing Group Company was the big boss in front of him.

The things decided by the big boss Huaxing Group must be implemented and completed, which is quite different from the business model of many neon domestic enterprises.

Many Neon domestic group companies have a large number of shareholders, and it is very difficult for these shareholders to reach a consensus when the senior management of the group company makes major decisions, and many strategic matters have been delayed for a long time.

However, there are several people on the board of directors of the headquarters of Huaxing Group Company, and only the big boss really has the right to decide, and Huaxing Group itself is not short of money at all, nor does it need to introduce capital from the outside, and the major strategic matters of the group company are decided by the big boss.

Huaxing Group Co., Ltd., which the big boss decided to do, immediately began to carry out this work, and the implementation speed was very fast, and the intensity was also very large.

Moreover, he also knows that the entire Huaxing Group now has 150,000 or 60,000 R&D and technical personnel from all walks of life, carrying out various R&D in many fields, and has 780,000 patents in his hands, and the number of patents is still increasing, so he can easily get rid of the patent barriers set by other companies.

A large number of technical patents of Huaxing Group can also be applied to tunnel boring machines, which is a huge advantage.

In the conversation just now, Yang Jie also clearly asked Huaxing Group to use the very advanced fuel cell technology and communication technology and electrification technology to develop a new tunnel boring machine, and Mao Tsuka's Tehiko and others also had great confidence in this.

"Mr. Yang, for the sake of safety, I suggest that the size of our first full-section tunnel boring machine should be set at six meters, what do you think?"

"The specific development of the size of the full-section tunnel boring machine still needs to be decided through market research, and we develop product technology to meet the needs of customers, which is our purpose. ”

Yang Jie said: "How to let customers improve construction efficiency and reduce construction costs when using our products is the most important thing." ”

Mao Tsuka, Tehiko and the others all nodded.

At present, the domestic subway is commonly used in the 6-meter tunnel boring machine, and the best full-section tunnel boring machine is the German Herrenknecht company, which has equipment with a diameter of four meters to 15 meters, and also produces automatic micro tunnel boring machine and horizontal directional drilling equipment with an outer diameter of only 10 cm.

Up to the year before last, Herrenknecht had supplied 40 tunnel boring machines with a diameter of more than 6 meters and 7 small machines to China.

The company has now supplied more than 1,200 tunnelling machines to customers worldwide.

At present, the global demand for tunnel boring machines is more than 800 sets every year, which has basically been carved up by dozens of overseas tunnel equipment manufacturers.

Ishikawajima Construction Machinery has been producing a total of 2,000 units including micro tunnel boring machines since the 60s before the acquisition, especially in the past few years, when it was only able to sell about 20 units per year, and the loss was very serious.

With the acquisition of Ishikawajima Construction Machinery, Yang aims to expand his production capacity to 100 TBMs per year in a few years.

At present, most of the domestic tunnel boring machines are imported, with a scale of more than 100 units, and Yang also hopes to get a large share in a short period of time, and at the same time export overseas.

Now the price of these domestic shield machines is too expensive, many domestic construction companies are unaffordable, Yang Jie also hopes to reduce the cost of the full-section tunnel boring machine as much as possible, so the key components are manufactured by their own company, even if the cost of equipment is pressed down, the company can maintain enough profits.

At this time, he also said to those involved in the research and development of excavators and other construction equipment: "Huaxing Construction Machinery Company also comprehensively uses fuel cells as power in excavators and other equipment, and then you should make more efforts in motor electro-hydraulic composite technology and motor variable speed load sensitivity technology to develop high-performance, environmentally friendly and low-energy construction machinery and equipment." ”

These technical experts all said that they would complete the tasks assigned by Yang Jie.
