Buckling Resistance Tester for Manhole Bases 


Standards

l  BS EN 14830      

l  BS EN 13598-2, Annex C  


Application

Buckling Resistance Tester is used to simulate the conditions when manhole is buried underground and check its resistance to the force from underground water.


Features

  •  High efficiency vacuum system provides a wide negative pressure range of -70kPa to 0kPa .

  • Specialized end caps are suitable for various of pipe samples.

  • Cantilever lifting structure is introduced to expand the testing space, making a wide range of manholes from Φ315mm to Φ1200mm.

  • Deformation sensors adjustable to different directions, are applicable to the conditions of uneven samples or reinforced sample surface.

  •  Industrial control terminal and colorful touch screen display provide more information to operator, e.g. pressure-time and deformation-time curves, leakage detection. Once there is leakage or unstability on sample, vacuum pump will stop working automatically.

  • Test data can be exported through USB port.

  • Test data will be saved automatically in case of abnormal interruption. Test time will be continued after system up to setting pressure.
