Northern Heavy Industries Group Co., LTD. Of Shield Machine In The Project Cost Control Research

China is the world’s tunnel and underground engineering, the most complex,most of the fastest growing country in the future, the construction of highway tunnel is the demand of the situation. Along with the social progress, technology development, the development trend of highway tunnel is a tunnel repair longer and longer, the more the more wide, technology is more and more complex, so more and more demand for shield machine. Shipment of shield machine is the realization of rock drivage, slag, such as the cave walls supporting an excavation hole of the high-tech construction equipment, is currently the world’s most advanced tunnel construction machinery. Shield machine technology diversity, set machine, electricity,liquid, control, measurement, is fast, efficient, safe and reliable, the construction of good quality, low cost and small disturbance to the surrounding rock mass, is conducive to protect the environment and reduce the labor intensity. The design of the shield machine involved in geotechnical mechanics, electro-hydraulic control, high wear-resistant materials research and application, remote sensing technology, the mechanism of rock fragmentation and extreme manufacturing technology, and other academic disciplines and edge is one of the world’s most complex super heavy construction equipment.Northern heavy industries and Germany wert cooperative development series of shield machine products, technology reached the international leading level, creating the largest diameter, drilling and tunneling feet maximum, drilling and digging tunnel length and so on many world records. Along with our country "15" during the railways, highways, urban subway, hydraulic engineering of a large number of start,begin to enter the underground space development and utilization of the rapid development stage, our country has become the world’s most populous country use of shield machine. Starting from 2006, along with our country the construction of a largenumber of start, shield machine market demand has increased dramatically, annual demand of 70 units, value of more than 70 one hundred million yuan. Shield the annual demand of our country is expected in the past 20 years will remain in the60-10 billion yuan, this is a very big market.In this paper, on the basis of a large amount of data, mainly used the research methods include: 1. Using the method of comparison, analysis of product price 2.Through a comprehensive market analysis 3.to predict the market situation by a large number of practical example analysis, comprehensively in this paper, the demand for the product. In terms of the special machine, has yet to begin research, domestic and foreign technology is mature, for example: different shield, broaching machine, and so on.China’s relevant departments should seize opportunity, technology import and independent development, shorten the gap with the developed countries, not only should be large, the application of tunnel excavating equipment will become the power of the development of equipment, increase the economic benefit and social benefit of engineering.
