Microtunnelling
Microtunneling is an up-to-date technology that allows installing pipes of different diameter in complicated geological conditions, i.e. rock formations, without excavation the surface. The most effective usage of micro tunnel panel complex is in condition of dense residential housing with the distance up to 1 km. To construct a collector two trenches are necessary, the first one - starting and the second one. The depth of trenches is corresponding to the depth of installation of pipes network. The set of required equipment components is composed in accordance with on the diameter of the collector, geological and local conditions. A standard model of a drive-in panel is equipped with a head with four ribs onto which rod cutters and gravers are installed. The ribs themselves also break bigger pieces of rock while driving in. The standard panel drives in the soil ranging from strength category 1 to category 5. The hydraulic control cylinders are installed inside on the panel and so it allows turning a controlled front side of the panel at an angle of up to 4º, thus changing the drive-in direction. The use of bentonitic mix and intermediate jacking stations allows to: Stationary or mobile electric or diesel units shall be used as power drives while driving in.
