A closed chamber device and method for model test gypsum test block

Abstract

The invention discloses a closed chamber device and method for model testing gypsum test blocks, including a compaction platform, a conveyor belt, a support frame, a plurality of compaction rods and a console, wherein the support frame is fixed on the compaction platform, and the conveyor belt It is installed on the compaction platform, located at the lower end of the beam of the support frame. There are multiple compaction rods arranged on the beam of the support frame in turn. The compaction rods can move up and down to hit the gypsum test block moving on the transmission belt. The console controls the movement of the transmission belt. Running and up and down motion of the compactor bar. Using the principle of layered packing and reducing the compaction contact area, it solves the problem that the gypsum test block is difficult to make dense in the past. The present invention uses compaction rod heads of different shapes to reduce the compaction contact area and increase the unit area of ​​gypsum. The impact force received, thereby increasing the compactness 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.
