Pipe jacking
General Details
The push tube also called pipe jacking is a no dig technology consisting of a horizontal drilling unguided followed pipe piling (locking tube or jacket tube).
Like all the no dig technology allows the installation of underground pipelines without performing open pit excavations.
The push tube technology is similar to microtunnelling but differs from this due to the absence of a drilling head placed on the drilling head and for the fact that the excavation can not be directed.
