TUNNELLING & MICRO TUNNELLING
Micro tunneling is a trenchless construction method in which a borehole is excavated, and pipes laid simultaneously using remote guidance, pipe jacking, and continuous support. The micro tunneling boring machine (MTBM) is operated from a control panel, normally located on the surface. Personnel entry is not required for routine operations.
Basically, microtunneling is remote pipe jacking. However, due to its cost, microtunneling is usually reserved for pipes that need a high degree of precision over a long distance. Water jetting is used for the cutting head during the boring stage, or an asymmetrical or slanted head and is directed using laser guidance. Only pipes with a circular cross-section can be used because of the boring process.
