Problems solved by technology

[0003] The single-lever consolidation instrument has the following problems: the pressure is applied to the sample through a fixed weight silicon code, and the pressure output is relatively stable, but it is also easily disturbed by external factors; there is a certain human error in the manual reading; there is a certain impact when the weight is manually applied There is a certain disturbance to the sample; all operations need to be done manually, which is inefficient; the present invention is mainly aimed at improving the commonly used single-lever consolidation instrument device

Abstract

The invention discloses a single lever type consolidation instrument and belongs to the technical field of mine geotechnical engineering. The single lever type consolidation instrument provided by theinvention comprises a digital display dial gauge, a consolidation device, a lever, a lifting platform and the lever type consolidation instrument. In the single lever type consolidation instrument provided by the invention, a lifting platform is installed on the base of the equipment to effectively reduce the impact force brought by manual weight application and the disturbance to the sample, thestopwatch is turned on to observe the change of the soil sample immediately after the load is applied to enable reduction of errors when applying the weight, a positioning groove is used at the position of the hook to enable the weight disk support rod to be firmly fixed in the positioning groove such that the double vibration mitigation can greatly reduce the errors when the weight is increased,a laser pen placement hole is arranged in the support frame and a laser pen can be placed in the laser pen placement hole such that a parallel laser beam is emitted after the laser lamp is turned onand can be used as a tool for auxiliary standard calibration, and the laser pen itself is low in cost, standard and efficient, and can be used as needed to reduce errors in adjusting the balance of the lever.

Description

technical field [0001] The invention relates to a single-lever consolidation instrument, which belongs to the technical field of mine geotechnical engineering. Background technique [0002] Consolidation test is a basic test item in engineering geological survey geotechnical test. The soil compression coefficient, compression index Cc, rebound index, consolidation coefficient, pre-consolidation pressure and other characteristic indicators can all be measured through consolidation tests. The test instruments mainly include single-lever consolidation instrument and automatic air pressure consolidation instrument. The single-lever consolidation instrument is currently widely used due to its low price and simple operation. Fully automatic air pressure consolidation is an automated equipment for geotechnical consolidation tests developed using computer technology, electronic technology, and control technology. However, the price and requirements for operators are relatively high...
