There are four key issues in China's tunneling machinery industry

At present, China has become the world's largest road-boring machine manufacturing base and application market, and domestic road-boring machines have also formed certain competitiveness in the international market. However, there are still many problems in the domestic road-boring machine industry.

Yu Hao, deputy secretary-general of China Construction Machinery Industry Association and president of the Drilling Machinery Branch, said that there are four major problems in China's tunneling machinery industry.

First, the industrial structure is not reasonable. As a large-scale high-end complex construction equipment, the full-face tunnel boring machine has relatively high requirements for the plant, equipment, capital, technology and talents of the enterprise. It requires a certain degree of industrial concentration and a large-scale production capability. There are faster developments and better benefits. However, the current situation is that there are many enterprises, the scale is small, the introduction is repeated, the power is scattered, and it is not strong. A considerable number of enterprises are basically assembly plants, doing 2 or 3 products a year, lacking independent research and development capabilities, and core technologies are not mastered. Such a large and scattered industrial structure is not conducive to the healthy development of the industry.

Second, a mature and unified market competition environment has not yet been formed. A unified, open and fully competitive market is an important condition for the healthy and sustainable development of the industry. In the current full-section tunnel boring machine market, segmentation, market monopoly and local protectionism are still relatively common. The reason is that, on the one hand, some of the roadheader manufacturing enterprises are developed by the construction unit or belong to the construction and construction unit. Therefore, after the construction unit undertakes the tunnel project, it tends to produce in this system or joint venture production. In order to get the most benefit. However, in the current bidding management measures, there are also “purchasers who can build, produce or provide their own projects”. The projects outside the system are difficult to obtain orders in such projects; On the one hand, in order to promote the local economic development, local governments tend to use local manufacturing equipment for local tunnel projects. Therefore, there have been many joint ventures and cooperative enterprises that have won the bidding service in a short period of time. These enterprises are generally contracted by foreign businessmen. And responsible, domestic enterprises only undertake structural parts manufacturing and assembly, resulting in the majority of the domestic shield machine market is occupied by foreign investors. In addition, since the full-face tunnel boring machine is the key equipment for tunnel construction, the owner tends to choose foreign brand products from the perspective of avoiding risks.

Third, the ability of independent innovation of enterprises needs to be improved. Some key core technologies have not yet been mastered, and product quality is not stable enough. Chinese manufacturers generally have a short development time, and the manufacturing technology of some key components is still immature. Key components such as main drive bearings, high-pressure hydraulic components and systems, sealing devices, sensors, and control systems still rely on imports. As the world's largest manufacturer of roadheaders, China must master the core technology of its products. Otherwise, it will be subject to people and will be extremely unfavorable to the development of the industry.

Fourth, industry management needs to be strengthened. An unorganized industry, the result is disorder. Yu Yu said that after the establishment of the club, it is necessary to focus on strengthening the work in this area, and play a good role as a bridge between the government and enterprises and users.
