Microtunneling is a pit-launched trenchless technique and uses laser-guided controls. Microtunneling is defined as a remotely-controlled, guided, pipe-jacking operation that provides continuous support to the excavation face by applying mechanical or fluid pressure to balance groundwater and earth pressures. Support at the excavation face is a key feature of Microtunneling. An entry or launch pit is excavated and provided with a jacking system and thrust wall.  Microtunneling is used to install pipelines that cross highways, railway lines, pipelines etc. MTBMs gives a high degree of accuracy compared to other trenchless methods. MTBMs can be used to bore through all types of soil, sand, clay and even through hard rock. Installation lengths can exceed 225 meters with dia up to 3000 mm. Even though Microtunneling is a bit more expensive than other trenchless techniques, the accuracy, reliability and lower maintenance cost of pipelines makes it a better choice.
