Summary |
Since the mud-pumping behavior is associated with the migrating of fluid inside the void of soil particles and the fluid would saturate the mud, to detect the motion fluid and saturated soil particles will be helpful to realize the distribution of mud-pumping. Moreover, the uplift pressure generated by pumping mud due to the cyclic loading from train can be adopted for the mentioned detecting work. It is just to lead the pumping mud into a casing tube firstly, and then detect the height The structural Schematic of Tubing-Floater Device design methodology is shown as Fig. 4. The entire set of the device includes casing tube and inside floater. The tube is adopted for leading the pumping mud to flow into the device and fill the chamber fully. The pressure generated from the mud inside the chamber will push the floater upward as the mud lift. For increasing the buoyancy, the floater is designed to be a raft-shaped. The outer surface of the floater and the inner surface of the tube should be close-fitting and slip smoothly. On the other hand, the tube should be a well cylinder. Otherwise, the floater will get stuck. A scale of distance that indicating the motion of floater is marked in the outside of the tube. The mentioned components are well-composed to be a Tubing-Floater Device. |
