500kNCompression Testing Machine

The tunnel shield segment bending test machine is designed and produced according to the requirements of the technical standard for quality inspection of shield tunnel segments: GB/T22082-2008 Reinforced concrete segments and CJJ/T164-2011 Standard for quality inspection of shield tunnel segment. It is mainly used to test the bending resistance and pullout resistance of the precast concrete lining segments of the subway tunnel. During the work, the segments are placed on the trolley, pushed into the bending and drawing space, and launched after the test.
