Multifunctional sampling, soil breaking and hole forming device

Abstract

The invention discloses a multifunctional sampling, soil breaking and hole forming device which comprises a hydraulic power device, a hydraulic telescopic rod, a protection barrel, a ring knife, soilbreaking cones and a hole forming barrel. The hydraulic telescopic rod is connected with the hydraulic power device and penetrates into the protection barrel through the top of the protection barrel.A threaded hole is formed in the output end of the hydraulic telescopic rod. The output end of the hydraulic telescopic rod is connected with the ring knife, the soil breaking cones or the hole forming barrel. A connecting plate is arranged at the top of the ring knife, and the ring knife is connected with the output end of the hydraulic telescopic rod through the connecting plate. The soil breaking cones and the hole forming barrel are connected with the lower end of the hydraulic telescopic rod through a threaded connecting rod. A circular ring is arranged on the outer side of the protectionbarrel. Three functions are integrated, the device controls the hydraulic telescopic rod to ascend and descend through the hydraulic power device, and the lower end of the device is detachably connected with the ring knife, the soil breaking cones or the hole forming barrel; and the circular ring on the outer side of the protection barrel is used as the reference of whether the protection can bevertically inserted into soil or not, deviation is avoided, hydraulic pressure is adopted as power, and the efficiency of sampling, soil breaking and hole forming is effectively improved.

Description

technical field [0001] The invention belongs to the field of geotechnical model test devices, and in particular relates to a multifunctional sampling device for breaking soil and forming holes. Background technique [0002] The geotechnical centrifugal model test uses the centrifugal force provided by the centrifuge to simulate gravity. According to the similarity criterion, the geometric shape of the prototype is scaled down. Consistent in the gravitational field, to study the testing technology of engineering properties, is a means to solve practical engineering problems and theoretical research. The geotechnical model test is used to simulate the force, deformation and failure of the prototype geotechnical structure, verify the design plan, conduct material parameter research, verify the mathematical model and numerical analysis and calculation results, and is widely used in the field of geotechnical engineering. [0003] The process of the model test includes packing an...

Problems solved by technology

After the experiment, the soil has a high degree of compaction, and the new piles need to be drilled. At this time, it is difficult to use manual drilling, which is easy to deviate and the accuracy is not high.

In addition, after the test is over, we usually need to unpack the box, take the soil out of the model box, and then carry out follow-up work and save it for the next test. Generally, the soil is broken by manpower, and the soil is cleaned slowly. Time-consuming and labor-intensive, not efficient
