2nd, a variety of settlement of foundation forms can be simulated.The present invention is connected to some electrical-controlled lifting devices 401 in tank bottom, leads to
Cross and control the displacement of each electrical-controlled lifting device 401 to simulate a variety of main storage tank settlement of foundation under various operating modes.This
The different sedimentation forms that invention can not only simulate tank skin can also simulate the different settling phases of tank bottom.
3rd, the deformation of storage tank and the surface stress of its tank skin can be quantified.There is measurement subsystem 5, it is not only in the present invention
The deformation of the tank body 201 of optional position, which can be measured, can also measure surface stress after deformation on tank skin, and tank bottom edge point
The amesdial 505 of cloth is capable of the numerical quantities of high-precision measurement storage tank sedimentation.The application of these measuring apparatus and means is to experiment
Result quantified to help the analysis of experimental result.
4th, in experimental tank medium recycling.Loading subsystem 3 in the present invention can realize the loading of medium in tank
With medium in unloading and recycling can, the recycling of medium is realized, reduces experimental cost.
5th, easy to operate, operating efficiency.Medium is injected into storage tank by loading subsystem 3, then controller 403 controls respectively
The displacement of individual electrical-controlled lifting device 401 just can be desired in advance storage tank sedimentation form, then carry out operating measurement subsystem 5
Carry out the measurement of experimental result.Experimental implementation is simple and convenient, saves the time, and operating efficiency is high, can complete multinomial work simultaneously.
