Embodiment Construction
[0026] The features of the present invention and other relevant features will be further described in detail below through embodiments in conjunction with the accompanying drawings.
[0027] The double-circle shield soil bin muck flow characteristic visual observation test system of the present invention includes four parts: a model soil box device, a scaled-down double-circle shield machine digging system simulation test device, a uniformly distributed load loading device and a commercial PIV digital image processing system. The uniformly distributed loading device adopts the method of stacking heavy objects; the commercial PIV digital image processing system is purchased from the market, equipped with a laser, a high-pixel camera and a PC with digital image processing software installed.
[0028] Such as figure 1 As shown, a uniform load loading device is installed above the model soil box device, a scaled double-circle shield machine excavation system simulation test device...
