  • description

  1. Main uses and scope of application

  

  This system is mainly used for testing compressive instability performance of plastic inspection Wells negative pressure test and sealing performance test of inspection Wells.

  

  The plastic inspection shaft compressive instability test (negative pressure) is used to test the resistance of the plastic inspection shaft base to the external load, which is mainly the underground water.

  

  Use head seal sample casing pipe and pipe nozzle, and on both sides of chute and placed at the bottom of the chute deformation of two groups of measuring devices, and then make the sample within a stable under negative pressure, and maintain more than 1000 h, record the chute time-dependent deformation, observed in the test specimen deformation, the phenomenon such as collapse, cracks, or crazing, extrapolation well base deformation of 50 years.

  

  Check well negative pressure test and sealing performance, used to check well resistance to negative pressure ability and system sealing.
