Product Description

JURBT-1 series buckling resistance tester is used to simulate the conditions when manhole is buried underground and check its resistance to the force from underground water.
Seal and vaccumize the sample between 20^.C-25^.C, keep the pressure stable for more than 1000h, measure the deformation of the sowchannel side and bottom, then extrapolate the deformation occurred after 50 years by least square method.
