A multipurpose on-site shearing instrument and method

Abstract

The invention discloses a multi-purpose on-site shearing instrument and method, comprising a base, a slide rail device, a loading device and a driving device arranged on the upper end surface of the base, a through hole for passing through the shearing box is opened on the base, and the through hole Two slide rail devices are arranged symmetrically along the length direction of the base. A loading device is slidingly connected to the top of the slide rail device. A through hole for placing the loading box cover is opened on the loading device. The two sides of the through hole at the top of the device are symmetrically provided with hinge lever devices along the length direction of the base, and the two symmetrical hinge lever devices are used together; the driving device is arranged on one side of the mobile device, and the shearing box includes an upper shearing box and a lower shearing box. The upper shear box and the lower shear box are connected by connectors, the upper shear box is detachably connected to the lower end of the loading device, and the lower shear box is detachably connected to the base; the invention can realize different types of interface shears by installing different components. Cutting and straight cutting and other multi-functional needs.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a multipurpose on-site shearing instrument and method. Background technique [0002] At present, in the field of geotechnical engineering technology, research on different types of rock-soil interfaces has become a hot topic. For the research on such interface problems, the existing technologies mainly include laboratory tests and field tests. Indoor test can accurately measure different mechanical parameters, and the test is accurate and reliable. It is the main research method at present, but limited by the size of the sample, it cannot objectively and accurately reflect the real nature of the interface; while the field test has high cost and long cycle, etc. The reason is that it has always been used as an auxiliary research method. At present, most of the field tests are due to the lack of a complete set of test instruments, resulting in uncontrol...
