Rapid high-water material strength detector and using method thereof

Abstract

The invention discloses a rapid high-water material strength detector and a using method thereof. The detector consists of four parts, namely a bracket system, a power system, an injection system and a measurement and calculation system. The using method comprises the following four steps: leveling a material, mounting-preparing, detecting and measuring-calculating. The rapid high-water material strength detector and the using method thereof disclosed by the invention have the novelty that the injection of a ball coronary measuring head is adopted, and the diameter of a round pit knocked by the ball coronary measuring head on the material is measured in the measurement and calculation process. The diameter measurement is intuitive and convenient, data measured by adopting the ball coronary measuring head are accurate and stable, and the technical effect of safely, conveniently and rapidly measuring the high-water material strength is achieved.

Description

technical field [0001] The invention relates to a high-water material strength detector and a method of use thereof, in particular to a strength detector capable of measuring the strength of high-water materials conveniently, quickly, in all directions and from multiple angles and a method of use thereof. Background technique [0002] High-water material, also known as high-water-speed solidification material, is a cheap, easy-to-use, pumpable support material with certain mechanical properties. It is mainly used for mining engineering roadway support, goaf filling, anchor spraying Supporting and other engineering materials can also be used as materials for underground engineering, underground cavern filling, grouting plugging, foundation reinforcement, etc. [0003] As a new type of material, at present, the strength test of high-water materials is mainly through indoor test tests, and there is no special instrument for instant and rapid on-site measurement.

AI Technical Summary

Problems solved by technology

[0005] 1. The measuring nail is too thin and penetrates too deep, making it difficult to remove the nail

Taking ZL96205094.6 as an example, the length of the measuring nail is between 20-50mm, the diameter of the measuring nail is between 2.5-6.0mm, the impact force is 300-950N, and the general strength of high-water materials is only 1-10MPa. Practice has proved that these The penetration-type mortar strength tester is too thin to penetrate too deep, and because the penetration is too deep and the strength of high-water materials is relatively low, the hole wall is likely to be damaged during the removal process of the test nails, and high-water material debris is generated and filled. The wall of the hole makes it difficult to remove the nail

[0006] 2. It is difficult to measure the penetration depth

Such a measurement process is cumbersome. Before the measurement, the measurement hole needs to be blown to remove the debris in the hole, and it is necessary to carefully put the measuring tool into the measurement hole and try to avoid collision with the hole wall so as not to cause the hole wall to collapse. All these lead to Difficulty in measuring penetration depth

[0007] 3. The measurement accuracy is low

Due to the relatively low strength of the high-water material, when using the measuring tool for re-measurement, the measuring tool may not be able to measure the measuring hole well due to improper force. Excessive force may cause the measuring tool to be pressed into the measuring hole and the high-water material will cause the measuring hole to deepen. And lead to larger measurement depth and low measured strength, small force will cause insufficient pressure of the measuring tool, resulting in low measured strength

In addition, during the removal of the measuring nail, the hole wall is easily damaged and high-water material debris is generated and filled in the hole wall, which will also affect the subsequent measurement of the measuring tool.

On the other hand, due to the thinness of the measuring nail, it is too sensitive to external influences during the penetration process, resulting in large fluctuations in the measured data

[0008] To sum up, at present, there is no rapid strength tester dedicated to high-water materials, and due to the particularity of high-water materials, the existing penetration-type rapid strength testers have many shortcomings and cannot be used well for high-water materials. strength determination
