Embodiment Construction
[0046] Such as figure 1 , figure 2 As shown, a test device for testing the flow characteristics of liquefied sand, including a vibrating table (14) and a model box (13) fixed on the vibrating table, also includes a low-speed adjustable motor (1), a dynamic displacement sensor (2) , fixed pulley (4), bearing (5), rigid round tube (7), small pulleys on both ends of the rigid round tube (15), steel wire rope (8), fixed pulley protection box (9), dynamic hole pressure sensor (10 ), dynamic tension sensor (11), plastic panel track (12), detachable panel (16) and plastic panel (17). The excitation direction of the vibrating table (14) is perpendicular to the direction of the plastic panel (12).
[0047] The plastic panel track (12) can be excavated on the plastic panel (16) by tools, and the excavated track surface is polished and smoothed. The detachable panel (17) is connected with the model box (13) by way of card slots, such as image 3 As shown, a card slot with a depth of...
