Technical Field

[0001] The utility model relates to the technical field of geotechnical tests, and particularly relates to a lever - type foundation load detection device. Background Technique

[0002] The lever - type consolidometer is a foundation load detection device. It is a device used for soil compression tests, mainly used to detect the relationship between soil pressure and deformation, calculate indexes such as the unit sedimentation, compression index, rebound index, and consolidation coefficient of soil.

As the pressing block 10 continues to move, As the pressure sensor 30 moves downward, the reaction force of the soil on the pressing block 10 continues to increase, and the pressure sensor 30 will transmit the sensed pressure to the display 21 for the convenience of the staff to watch. When the wire rope 5 is in a relaxed state, the pressure of the pressing block 10 on the soil is the maximum, and the load detection can be realized. The pressing block 10 can be disassembled and replaced as needed before use. The knob 96 is turned to drive the threaded rod 95 to rotate. When the threaded rod 95 rotates, it will drive the movable plate 93 to move. When the movable plate 93 moves, it will drive the positioning rod 92 to move backward and away from the inner cavity of the positioning hole, so that the clamping block 91 can be released. Then the pressing block 10 can be taken out by moving downward, and vice versa, it can be re-clamped and fixed.
