Usage of the jacking pipe and its advantages

Tunnels have become extremely important in the execution of work in big urban areas in most of the world because they mean solution to transposition of a multitude of obstacles.

The "jacking pipe" system represents one of the most recent technological advances amongst existing methods for tunnels execution in urban areas.

The system consists of the tunnels execution within several diameters through "inserting" high resistance concrete tubes (50 to 80 MPa), meant for general channeling (pluvial drainage, sanitary system, sewer galleries, etc.). That system allows works execution in urban areas without traffic interruption, making interference transposition easier and avoiding buildings and lands expropriation.

Jacking pipe system still has other advantages such as inserting equipment versatility and diverse kinds which permit tunnels execution on rocky, sandy and muddy terrains with or without porting capacity and whether or not water containing, besides that those inserting concrete tubes are already normalized in Brazil - NBR 15319/2006.

Therefore, here are some advantages of that system: They are under normative specifications, being used in urban areas, without traffic interruption, without buildings and lands expropriation, interference transposition simplicity, multitude of diameters, electric and telephonic ducts channeling, execution on all kinds of terrains, etc.
