Embodiment 1
[0031] Embodiment 1, a kind of high-pressure penetration test sealing method, has adopted described sealing method, comprises the steps:
[0032] Step 1: Return all push plates of the instrument to their original positions;
[0033] Step 2: Glue a circular rubber sheet around the water inlet hole of the water inlet push plate and the water outlet hole of the water outlet plate, and place a rubber sheet inside the test chamber. The rubber sheet covers the front, bottom and rear sides of the instrument ( Except for the water inlet surface, water outlet surface and top), the specific size and model of the rubber sheet is determined by the calculated peak shear strength and the thickness of the rubber sheet allowed by the instrument;
[0034] Step 3: Put in the custom-made water bladder, place the geotextile and the rubber sheet in sequence on the water inlet side of the bladder body, and place the rubber sheet on the water outlet side;
[0035]Step 4: Fill the test soil sample f...
