Professional manhole cover pressure testing machine - precise detection, safeguarding urban safety!

The manhole cover pressure testing machine is a specialized equipment used to test the bearing capacity of municipal manhole covers, drainage covers, composite manhole covers, etc. It is mainly used to evaluate their compressive strength, deformation performance, and durability to ensure compliance with national standards (such as GB/T 23858-2009, EN 124, etc.).

1. Equipment functions and testing standards

(1) Main testing items

Vertical static load test: Simulate vehicle rolling and measure the ultimate bearing capacity of manhole covers (such as A15/B125/C250/D400/E600/F900 grades).

Residual deformation test: After unloading, check whether the manhole cover has been restored to its original state.

Fatigue test (optional): Simulate long-term vehicle traffic and test durability (such as 100000 cycles of loading).

(2) Applicable standards

2. Equipment structure and composition

(1) Host framework

Four column structure: high rigidity design to ensure loading stability.

Hydraulic/Electric Loading System:

Hydraulic type: large tonnage (usually 1000kN~5000kN), suitable for high-strength testing.

(2) Key components

Pressure sensor: Real time monitoring of test force (accuracy ± 1%).

Displacement sensor: measures the deformation of the manhole cover (e.g. 0.01mm resolution).

Control system: PLC or computer control, automatic loading, holding, and unloading.

Safety protection: Explosion proof glass cover or fence to prevent sample breakage and splashing.

(3) Auxiliary device

Manhole cover fixing fixture: Simulate actual installation conditions (such as support brackets).

Environmental simulation module (optional): High and low temperature chamber, testing performance under extreme temperatures.
