Plastic check the mechanical properties of the well

Well base structure design

When the plastic inspection well is buried underground, the dynamic load acting on the vertical direction of the well cover, the weight of the well body and the drag force acting on the wellbore constitute the vertical load of the inspection well. All vertical loads are transferred to the well seat, which is the core part of the plastic inspection well component.

Vertical stress analysis

Because the model is too large and the main surface of the model is an irregular surface, the analysis cannot be carried out due to the interleaving of the longitudinal, transverse and oblique stiffeners. On the basis of not considering the diagonal reinforcement, the horizontal reinforcement is simplified when the vertical force is analyzed. When the horizontal force analysis is done, the vertical reinforcement is simplified. The result of this analysis will be that the strain is slightly greater than the actual situation, and the stress is about the same. Calculation data: the weight of a single wheel of the car is 80KN (8 tons). The calculated stress is 18MPa.
