[0017] The inner wall of the inner ring support plate is fixed with an intermediate support plate, and a plurality of reinforcing rib pipes are arranged between the intermediate support plate and the upper bottom plate and between the intermediate support plate and the lower bottom plate.

[0018] The intermediate support plate and the two layers of reinforcing rib pipes can increase the support stability of the upper bottom plate to the hydraulic cylinder, prevent the upper bottom plate from deforming during the pressure test of the manhole cover, and affect the test results.

[0019] The utility model further sets up: the reinforcing rib pipes of the upper layer and the reinforcing rib pipes of the lower layer are staggered, which can further improve the structural stability between the upper bottom plate and the lower bottom plate and further reduce the risk of deformation.
