Dense device and method for gypsum test block of model test

Abstract

The invention discloses a dense device and method for a gypsum test block of a model test. The dense device comprises a compaction platform, a conveyor belt, a supporting frame, a plurality of compaction rods and a console, wherein the supporting frame is fixed on the compaction platform, the conveyor belt is arranged on the compaction platform and is located at the lower end of a cross beam of the supporting frame, the plurality of compaction rods are sequentially arranged on the cross beam of the supporting frame and can move up and down to strike the gypsum test block moving on the conveyor belt, the console controls the operation of the conveyor belt and the up and down movement of the compaction rods. By adopting the principle of layered filling and reduced compact contact area, the problem that a gypsum test block is hard to be compact is solved, by virtue of compaction rod heads with different shapes, the compact contact area is reduced, and the compact force applied to the unit area of gypsum is increased, so as to increase the density of the test block.

Description

technical field [0001] The invention relates to a closed chamber device and method for a model test gypsum test block. Background technique [0002] Model test is a method to conduct scale-down research on specific engineering geological problems according to a certain similarity principle. It has become the most important method in the engineering field to obtain relevant data and check design defects by performing corresponding tests on scaled-down or proportional models. one of the research tools. [0003] As one of the most commonly used test materials, gypsum has the characteristics of good cementation, fast hardening speed, and good processing performance. It is widely used in model tests, especially for simulating rolling stones and slopes. This type of model test often requires the production of gypsum test blocks to meet the requirements of the test conditions. The density of the test block is the key factor determining the quality, strength and accuracy of the tes...

Problems solved by technology

This type of model test often requires the production of gypsum test blocks to meet the requirements of the test conditions. The density of the test block is the key factor determining the quality, strength and accuracy of the test results of the test block. In the process of making the gypsum test block, due to Its hardening speed is fast, and the test block needs to be completed in a short time. It is difficult to control its compactness by conventional manufacturing methods, thus affecting the accuracy and effect of model test results.
