For busy traffic areas, and below highways, rivers & railway lines
Another trenchless method, pipe jacking is where the concrete pipe is pushed by a powerful hydraulic jack with a cutting head that excavates the ground to make way for the pipe. The ground is supported and any potential movement is reduced. Smythe Contractors have achieved installation by pipe jacking below highways, in busy high traffic areas, under rivers and beneath railway lines.
Installation for larger steel pipes
Smythe Contractors Ltd utilise pipe ramming methodology for installation of larger diameter steel pipes under highways and railways, for water and sewer lines. An impact hammer attached to the rear of the pipe drives the pipe in. Similar to pipe jacking, the impact hammer rams the pipe so the need for a jacking reaction is eliminated.
