Title:
TEST DEVICE AND METHOD FOR MEASURING FRICTIONAL RESISTANCE OF THIXOTROPIC MUD
Document Type and Number:
WIPO Patent Application WO/2022/105840
Kind Code:
A1
Abstract:
A test apparatus and method for measuring the frictional resistance of a thixotropic mud, the test apparatus comprising: a test platform (1). A prefabricated concrete block is filled in a sliding box (2) and is used for simulating an on-site reinforced concrete box culvert, and a thixotropic mud (13) is spread on the surface of the concrete (12). A loading apparatus is loaded above the concrete (12) along the longitudinal direction, and a soil sample (14) is filled in the loading apparatus, in order to simulate an overlying soil mass on the box culvert in a jacking construction process, and once loaded, the soil sample (14) is in contact with the thixotropic mud (13). A horizontal force gauge (7) is horizontally fixed onto a side portion of the loading apparatus, and a baffle (18) facing the horizontal force gauge (7) is arranged on the test platform (1). The sliding box (2) is driven to slide along the test platform (1) towards the baffle (18), and the baffle (18) blocks the horizontal force gauge (7), so as to produce sliding displacement between the loading apparatus and the sliding box (2), and the frictional resistance between the soil sample (14) and the concrete (12) is displayed by means of the horizontal force gauge (7), thereby simulating the interactions between a box culvert, mud, and overlying soil in the box culvert jacking process.
