Abstract

The invention relates to a portable multifunctional soil mechanical property test device. The portable multifunctional soil mechanical property test device comprises an upper rigid beam, a lower rigid beam, a rigid threaded column, an upper stress application mechanism, a lower stress application mechanism, a water tank, a test tank, a measuring mechanism and an infiltration mechanism, wherein the middle part of the lower rigid beam is provided with the lower stress application mechanism, the lower stress application mechanism is provided with the water tank, the test tank is arranged in the water tank, the upper rigid beam is arranged on the lower rigid beam in an up-down moving manner through the rigid threaded column, an inner screw hole is formed in the middle of the upper rigid beam, the upper stress application mechanism passes through the inner screw hole and is connected with the test tank through the measuring mechanism, and the test tank is communicated with the infiltration mechanism through a water guide pipe. Compared with the prior art, the portable multifunctional soil mechanical property test device is simple in structure, convenient to carry and easy to operate; soil tests can be conveniently carried out in an engineering field, the test error can be effectively reduced, the working efficiency is high, the practicability is high, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering geotechnical testing, and relates to a portable multifunctional soil mechanical property testing device. Background technique [0002] Foundation pit engineering and underground engineering often need to measure soil physical and mechanical parameters in the investigation stage. At present, most of the methods used are to take samples and send them to the laboratory for testing. However, in the process of transportation and storage, soil samples are often disturbed twice, which affects the accuracy of soil mechanical parameters, which will cause risks to later engineering design and construction. In addition, due to the long laboratory test cycle, the test data is often not obtained in time, which will increase the project cycle. [0003] The Chinese invention patent with the application number 201210390847.6 discloses a test device for real-time measur...

Problems solved by technology

The device published in this patent uses counterweights for loading, which cannot effectively control the loading accuracy, and cannot meet the needs of fine testing of expansion force. It uses water injection holes. For general consolidation tests, the saturation efficiency is low and it may not be possible to The air is completely exhausted. At the same time, due to the separate existence of each test component, the volume space of the device is greatly increased, and it is not conducive to the rapid and convenient movement of the device, and it is not portable.
