Along with our country economy sustained steady growth, further accelerate the speed of urbanization, the demand of underground pipeline in our country also increased year by year. Combined with the enhanced awareness of environmental protection pipe jacking technology will be the construction of underground pipeline in our country to play a more and more important position and make use of. The development of trenchless technology will surely to scale, standardization and internationalization direction.
With the support of China’s rapid economic growth, the development of pipe jacking technology will face unprecedented opportunity and in accelerating the introduction of foreign advanced technology, basically trying to digest the innovation, strengthen the research and development and personnel training, the prospects are very optimistic. Throughout the development of the pipe jacking technology at home and abroad, development direction will be diversified and diversification.
In terms of diameter of pipe jacking, except to the top of the large diameter pipe into development, also to the development of small diameter pipe jacking. The minimum pipe jacking technology in jacking pipe diameter is 75 mm, the largest has reached 5 m (Germany), large diameter pipe jacking has a tendency to replace the small shield. In terms of adaptability, wide development scope, the soil type pipe jacking is inevitable trend, to adapt to the range will be greatly extended, from soil N value is very small to the value of N for more than 50 gravel, until the axial compressive strength of two hundred MPa. The microelectronic technology, industrial sensing technology, real-time control technology and modern control theory and the mechanical, hydraulic technology is comprehensive used in pipe jacking machine pipe jacking technology development trend. Digitalization and informationization, the development of intelligent pipe will get more attention, correction precision, will gain a large of automation
