→Used in bearing capacity of precast concrete lining pipe segment, fiber concrete pipe segment, steel segment of steel segment and composite pipe segment, apply flexural design load, detect the deformation of pipe segment under flexural load, detect the generation and change of cracks on the surface of pipe segment, and evaluate the flexural performance of pipe segment.
→Used in bending test for tubes (precast concrete lining tubes) : bending test, bending test, horizontal displacement measurement point of tubes, graded loading test of tubes, constant load test of tubes, measured value of cracking load of tubes, maximum crack width of tubes, and bending load test of tubes.
→Used to segment thickness (300 mm / 350 mm / 500 mm / 600 mm / 650 mm), the segment width (1000 mm / 1200 mm / 1500 mm / 1800 mm / 2000 mm), segment diameter (3000 mm / 5400 mm / 5500 mm / 12000 mm / 13700 mm) and so on size segment flexural performance test standard block (B).
→Used in determination of the bending resistance for tunnel concrete pipe slices and steel pipe slices before the construction of pipe slice production line, shield tunneling method, underground excavation method, tunneling machine method and sinking pipe slice construction.
