What are the advantages of trenchless technology?
With the development of trenchless technology, many engineering projects have begun to spread. So what are the advantages of non-excavation technology?
1. Use compressed air to break into the pipe without back pressure.
2. The occupation of working wells (pits) is small and the construction cost is saved.
3. The construction speed is fast, and the pipe is about 10 meters per hour.
4. The construction method is safe, and no construction workers are required to work in the working well (pit).
5. When encountering special soil quality, such as sand pebbles, quicksand, groundwater, etc., there is no impact on the construction of the stern tube.
6. The pipe is easy to unearth, and the compressed air is used to discharge the soil once, and the earth discharging speed is fast and safe.
7. The project cost is low. Compared with the ordinary pipe jacking method, the project cost is close.
8. Non-excavation pipeline construction can be carried out under normal conditions such as trains, cars and other vehicles without deceleration and continuous river flow, so it has high environmental and social economic benefits.
