In the near future, some automatic, high precision of excavating the opportunity to become the mainstream of construction machinery. Pipe jacking purposes with the development of related technology will also continue to expand, it is mainly used for gas pipelines will develop pipeline laying, culvert jacking, underground pedestrian passage pipe roof construction such as multi-purpose type.
Pipe jacking section is essentially round shape, the future is the development trend of circle, rectangle, round arch, polygon, etc., to meet the needs of the box culvert jacking, etc all kinds of engineering, so the cross section shape diversification is the inevitable trend.
Pipe jacking construction form is mainly for the soil pressure type, pressure type, future development will be further on the basis of absorbing foreign technology, the application of pipe sleeve type, bubble and so on various types of pipe jacking construction technology. With the development of high precision distance measurement technology to further application, the improvement of the ventilation system, relay technology, grouting friction between the progress of technology, Slag discharge system, the development of the knife dish unearthed conveying system, cutting system, propulsion system, power supply guide hydraulic system, monitoring system, measuring system, and a series of technical breakthrough, existing one-time into the distance will be constantly refreshed, all kinds of complicated curved pipe jacking will also appear in succession.
