A Soltau Model RVS 250-AS-STS microtunneling machine with a slurry spoil removal system was selected on a lease arrangement to install the 24-in. sewer line. A mixed face cutting head configuration was selected in anticipation of the varying ground conditions. The unit is supplied with high pressure water jets which have proven effective in boring through dense clays. The RVS 250-AS-STS involves two new innovations. First, it utilizes a state-of-the-art laser guidance system coupled with a completely digital operator control panel with continuous, up-to-date information on the tunneling process. A data logger, which can record data at specific time intervals or length of pipe jacked, also provides for a permanent record of the operation.  1, record 1, English, - microtunneling%20machine

Microtunnelling is becoming increasingly important. Whether house connections, gas and water pipelines, pipe renovation or laying cables - the principle of underground pipe-jacking has proven successful. Essential advantages are environmentally friendly processes, minimized disturbance to public highways, easy working in urban areas, economical management... Auger material removal will be applied in soil without ground water. The advantages of the auger system: Simpler machine design than the AVN system and direct discharge of the excavated material, especially with cohesive ground.  3, record 2, English, - auger%20system

Microtunneling specifications... The measuring and balancing of earth and ground water pressure shall be achieved by use of a slurry or cased auger system. The system shall be capable of incremental adjustments to maintain face stability for the soil conditions encountered... The system shall monitor and continuously balance the soil and ground water pressure. The system shall be capable of adjustments required to maintain face stability for the particular soil condition to be encountered to prevent loss of soil or uncontrolled ground water inflow.  4, record 2, English, - auger%20system
