Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0030] Such as figure 1 As shown, the present invention provides an intelligent geotechnical penetration shear test system, which includes a pressure chamber 101, and the top and bottom of the pressure chamber 101 are respectively provided with a pressure chamber top plate 102 and a pressure chamber bottom plate 103. An inner pressure chamber 106 is provided in the pressure chamber 101 , and the volume change test of the sample during shearing is performed by setting the pressure chamber 101 and the inner pressure chamber 106 . The sample 107 is set inside the inner pressure chamber 106, and the top cap 104 is in indirect contact with the top of the sample 107 through permeable stones and filter paper. The base 105 is in contact with the bottom of the sample 107 . The axial...

Abstract

The invention provides an intelligent geotechnical permeation shearing test system. An auxiliary water addition and drainage system is arranged in a triaxial test, when water addition is needed in a controller, degased water in a water tank is injected into the controller; when drainage is needed in the controller, the water in the controller is drained to a recirculating water tank at another place. The intelligent geotechnical permeation shearing test system is equipped with an electronic valve, and the lines of all electronic switches are connected with a data acquisition board and a computer, so that the computer controls all of the valves; and as for the software development intelligent APP in the computer, when a smart phone is installed with the testing system APP, under a networking state, the testing progress can be observed at any moment, and the control of the electronic switches in the equipment and the control of the testing process are realized.

Description

technical field [0001] The invention belongs to the technical field of seepage shear tests, and particularly designs an intelligent geotechnical seepage shear test system. Background technique [0002] In geotechnical engineering, the update speed of geotechnical test equipment is very fast. With the development of basic sciences such as chemistry, mechanics and physics, various new sensors and control systems continue to penetrate into different aspects of geotechnical engineering testing. The development of these sensors, data collectors and controllers has improved the accuracy of geotechnical testing and promoted the progress of geotechnical testing instruments. At present, there are relatively few equipments capable of performing seepage shear tests in geotechnical engineering, and only triaxial instruments and some ring shear instruments can be performed. [0003] The osmotic shear in the existing equipment is mainly based on the servo motor controller to control the...
