影響因子In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase in economic incentives to the user. Because the operating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to be shared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children‘s book of definitions wrote, "A Hole .. .Is to Dig." But this statement is not necessarily true. Today, a hole could be to bore.

Background, has not said” (Braude 1965). History provides a data bank of experiences, and if we take heed, we should be spared the futile but often popular pastime of reinventing the wheel. History also reveals the technological and economic choices that have shaped the products we have today and helps to guide us in the choices we will make in the future.

Future Needs,ew installations with a 100-year working life. Fortunately, engineers working in the nineteenth century also held this view, and their utility systems still serve us. If utilities are to accept new ideas, they must be assured of the long-term performance and durability of what is being proposed.
