Characteristic features of professional production trenchless trenchless drilling rig drilling rig manufacturers and engineering characteristics of trenchless drilling rig engineering trenchless engineering compared with other technologies, trenchless technology started late. But it is worth noting that in the last 20 years, small and medium sized horizontal directional drilling, trenchless technology, whether in theory or in terms of the construction process, there is a rapid development. Trenchless technology is a very important city in the construction of pipelines means laying pipes using trenchless technology has several unique advantages. Trenchless technology has been widely used in foreign countries, the increasing popularity in the country. Not digging the ground, will be able to cross roads, railways, rivers horizontal directional drilling rig structure, even through underneath the building is a construction method can be performed safely and effectively for environmental protection. Trenchless technology is not digging the ground, and therefore the upper soil layer is laid undisturbed pipeline, the pipeline is not easy to produce pipe section ends stepped deformation, the tube life is also greater than the pipe excavation method.
