TBM Test apparatus for predicting performance of soft ground Tunnel Boring Machine

摘要

The present invention relates to an apparatus and a test method for evaluating the performance of a pavement for predicting the performance of the TBM of the soil. More particularly, the present invention relates to an apparatus for evaluating soil earth TBM pumping performance, comprising: a housing; A compaction sample box provided at a lower end of the housing, the compartment being opened at an upper portion thereof and having a compaction soil inside; A soil chamber formed at the upper side of the compaction sample box in the housing, the soil chamber being formed by the excavation of the soil in the compaction sample box, the clay being introduced into the interior of the compaction sample box; A compact blade provided at a lower end of the soil chamber and provided with a cutting tool for excavating the soil within the compaction sample box and a foam inlet through which the foam is injected toward the soil side; A servo motor for rotating the small blade; A clay unit provided in the clay so as to adjust an amount of clay to be clay; A lower portion for moving the small blade toward the soil side to apply a vertical load to the soil side; And a foam injecting means for injecting a foam having a mixing ratio set to the side of the foam injection port.
