Description

JJRBT Buckling Resistance Tester for Thermoplastic Manhole
Overview
JJRBT-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 vacuumize the sample between 20℃~25℃, keep the internal negative 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.
Standard
BS EN 14830, BS EN 13598-2 and the equivalent.
