Portable environment-friendly plastic box device for storing karst test pieces

Abstract

The invention discloses a portable environment-friendly plastic box device for storing karst test pieces. The box device comprises an upper box body and a lower box body, the upper box body is hingedto the lower box body through a first hinge and a first lock catch, an upper disc and a lower disc which are arranged up and down in an overlapped manner are arranged in the upper box body and the lower box body, the two sides of the upper disc and the two sides of the lower disc are hinged to the side wall of the upper box body and the side wall of the lower box body respectively through symmetrically arranged connecting rod sets, the upper disc and the lower disc are each of a square box body structure with an upper opening, first partition plates are fixedly connected between the front andrear walls of the upper disc and between the front and rear walls of the lower disc, cylindrical boxes arranged between the first partition plates, and the test pieces are placed in the cylindrical boxes. After the test pieces are made, the device is used for safely storing the test pieces, the device is placed in a special protection box, and the effects of external force isolation, moisture prevention and moisture absorption can be achieved. The device is also convenient to carry, and a good effect is achieved.

Description

technical field [0001] The invention relates to a karst test piece, in particular to a portable environment-friendly plastic box device for storing the karst test piece, and belongs to the technical field of geotechnical research. Background technique [0002] The standard dissolution test piece method was introduced into China by Academician Yuan Daoxian in the 1980s, and is mainly used in karst areas in southwest my country. According to the weight change before and after it is buried in the soil, the dissolution amount and dissolution rate of a certain karst area can be calculated. The standard karst test piece is generally made of relatively pure limestone into a cake-shaped stone piece with a diameter of 40mm and a thickness of 3mm. Its thin and small characteristics are easy to damage the limestone test piece, and its weight will also change when it is infiltrated by water vapor. [0003] According to field experience, during the process of making, weighing, storing, ...

Problems solved by technology

However, the ziplock bag is soft and thin, and is vulnerable to the infiltration of moist gas and the impact of external forces, such as scratches, collisions, artificial smashing of hard objects, human trampling, water or water vapor intrusion and other uncertain factors, often resulting in karst testing. Tablet weight change or breakage

Although karst specimens are taken from carbonate rocks, the cost of making a single slice is relatively expensive and time-consuming
