Industries Using Trenchless Technology Methods
Monte Vista Group is involved with trenchless technologies and the following are typical applications for new, replacement or rehabilitation of 2 through 102-inch diameter piping systems:
- Storm-water
- Industrial Effluents
- Sewer Interceptors
- Sewer Lines
- Force Mains
- Water Supply
- Salt Water Lines
New Pipeline Construction or Replacement
- Auger Boring: This is a trenchless construction method used to install a casing by hydraulically pushing the pipe through the ground and removing the spoil through the pipe using an auger.
- Micro Tunneling & Pipe Jacking: This is a trenchless piping construction method that pushes the pipe into place (i.e., pipe jacking) behind a micro tunnel boring machine that is remotely controlled.
- Direction Drilling: This is a trenchless construction method that employs a directional drill to bore a horizontal tunnel. The tunnel is then reamed to remove the spoil and may be filled with bentonite slurry to maintain tunnel stability. The pipeline is assembled above ground, pulled or pushed into the tunnel and anchored.
- Utility Tunneling & Carrier Pipe: This method involves excavating the ground at the leading edge of a shield or boring machine and erecting a lining system from within the excavated space.
Pipeline Renewal Technologies
- Slip lining: This is a construction method used for pipeline installation inside an existing host pipeline. Although slip lining reduces the inside diameter of the pipe, the reduced inflow and infiltration combined with the smooth interior of plastic or fiberglass slip lining materials increase the hydraulic flow.
- Pipe Bursting: Pipe bursting tools are used in slip lining to provide access in collapsed or narrow sections of the host pipe and if the pipe diameter is being increased.
