Embodiment Construction
[0022] 1. According to the needs of the experiment, prepare a remolded soil sample with a certain moisture content. The soil samples prepared for each group of tests should be greater than 8kg.
[0023] 2. Connect the compacting cylinder to the base and place it on the rigid foundation stably. Install the casing, apply a layer of lubricating oil evenly on the inner wall of the compaction cylinder, weigh a certain amount of sample, pour it into the compaction cylinder, and fill in layers. First, a 40mm soil sample was filled, and a pore water pressure sensor was placed horizontally in the center; the pore water pressure sensor was surrounded by saturated artificial filter material to ensure the accuracy of pore water pressure measurement. Then fill in a 40mm soil sample, and place an earth pressure sensor horizontally in the center; evenly spread 1.5cm thick fine sand on the upper and lower surfaces of the pressure box to ensure that the earth pressure box is evenly stressed. ...
