Microtunneling (MT) can be described as a remotely controlled, guided pipe jacking process that provides continuous support to the excavation face. It can be used for installing conduits beneath roadways in a wide range of soil conditions, while maintaining close tolerances to line and grade from the drive shaft to the reception shaft. The Microtunneling process is a cyclic pipe jacking process.
There are two types of MT methods: slurry type and auger type. In the slurry type method, slurry is pumped to the face of the MTBM. Excavated materials mixed with slurry are transported to the driving shaft, and discharged at the soil separation unit above the ground. In an auger type method, excavated materials are transported by the auger in the casing, and directly discharged on the ground.However, the auger type MT is not popular these days. The slurry MT system is capable of handling wet, unstable ground conditions. The slurry MT system has five independent systems: one of the independent system is slurry separation system.
GN Solids Control is a API certified solids control equipment manufacturer in China. we are professional at separation of solids from liquid. Whether it is a high volume of large solids or a large volume of very fine solids. GN has the expertise,experience,and equipment to do the job.
The typical GN Separation System consists of a primary shale shaker. desander,desilter, centrifuge. Systems are engineered to your tunneling requirements for size,volume ,and process capacity. The objective of any GN separation system design is function,simplicity,and ruggedness. So far ,GN Solids Control have exported our separation system to over 60 countries. Including Australia, some Europe countries. GN has the solution to your Microtunneling.
