Characteristics of non-excavation works:

Compared to other technologies, trenchless technology started late. However, it is worth noting that in the past 20 years, non-excavation technology has developed by leaps and bounds both in theory and in construction technology. Non-excavation technology is an extremely important construction method for urban paving pipelines. The use of non-excavation technology to lay pipelines has several unique advantages.

Non-excavation technology has been widely used abroad and is gradually becoming popular in China. It is a construction method that can safely and effectively carry out environmental protection without digging the ground, passing through roads, railways, rivers, and even under the building.

The non-excavation technology does not excavate the ground. Therefore, the upper soil layer of the pipeline is undisturbed, and the pipe joint end of the pipeline is not easy to produce step deformation, and the pipeline life is also greater than that of the excavation method.

The use of under-stolen trenchless technology can save a large amount of land acquisition and demolition costs, reduce the use of relocated houses, shorten the length of pipelines, and has great economic benefits.
