1.Introduction
The machine according to CJ/T3012-1993 cast iron manhole cover, CJ/T121-2000 regenerated resin composite material manhole cover and JC889-2001 "steel fiber concrete manhole cover, GB/T 23857-2009 the manhole cover industries or national standard design and production, BS EN 124:1994 ,is used for the bearing capacity of the manhole cover test. The structure performance completely conform to the requirements of the test specification. Note: HT materials do destructive test sample; QT samples or other composite material circulation, deformation, destruction test.
