Description
Technical field
The present invention relates to a kind of high-water material intensity detector and using method thereof, particularly a kind of can convenient fast, all-dimensional multi-angle measures intensity detector and the using method thereof of high-water material intensity.
Background technology
High-water material, also known as the solid material of high-moisture quick-setting, a kind of inexpensive, easy to use, and there is the pumpability support material of certain mechanical property, be mainly used in the construction materials such as mining engineering roadway support, goaf filling, bolt-spray support, also can be used as the use material of underground works, underground chamber filling, grouting for water plugging, foundation stabilization etc.
As a kind of new material, at present, the strength test of high-water material is tested mainly through shop experiment, and on-the-spot instant Quick Measurement there is no specialized equipment.
And the instant Quick Measurement instrument in existing similar material working-yard, for injection type mortar strength detector (as Chinese patent ZL94219060.2, ZL96205094.6, ZL01201111.8 etc.), these instruments all adopt surveys nail as penetrator.For high-water material, these instruments have the following disadvantages:
1, survey the meticulous injection of nail excessively dark, get nail difficulty.For ZL96205094.6, survey nail length between 20-50mm, survey nail diameter between 2.5-6.0mm, impulsive force 300-950N, and high-water material common intensity only has 1-10MPa, facts have proved, it is excessively dark that these injection type mortar strength detectors survey the meticulous injection of nail, and because injection is excessively dark, high-water material intensity is relatively on the low side, survey nail in taking-up process, easily cause hole wall breakage and high-water material chip to produce and filling hole wall, cause getting nail difficulty.
2, depth of penetration measures difficulty.Adopt and survey nail penetration method and generally need to measure nail depth of penetration with special measuring tool, the compressive strength of the surveyed mortar that then converted by the relation of the survey of setting up in advance nail depth of penetration and mortar compressive strength.This " special measuring tool " is generally employing and reinserts gaging hole measurement with the spike measuring tool surveying the same specification of nail, reads the gaging hole degree of depth with vernier caliper or more advanced digital display device.Such measurement operation is loaded down with trivial details, need to blow off process to gaging hole before measuring hole intraclast is removed, and needing careful gaging hole of being put into by measuring tool also to try one's best collision free hole wall in order to avoid cause hole wall collapse, these all result in depth of penetration and measure difficulty.
3, accuracy of measurement is on the low side.Because high-water material intensity is relatively low; when using measuring tool to remeasure; usually measuring tool can be caused can not to measure gaging hole well because of undue force; conference of exerting oneself causes measuring tool to be pressed into high-water material in gaging hole to cause gaging hole to deepen and cause fathoming and become large and institute surveys low strength, and little meeting of exerting oneself causes measuring tool press-in deficiency to cause surveyed low strength.And survey nail easily causes hole wall breakage and high-water material chip to produce and filling hole wall in taking-up process, also can affect the measurement of follow-up measuring tool.On the other hand, meticulous owing to surveying nail, affect too responsive in penetration process to external world, cause surveyed data fluctuations excessive.
In sum, there is no the intensity Quick testing instrument that high-water material is special at present, and due to the singularity of high-water material, there is many deficiencies and can not perform well in high-water material strength detection in existing penetration type intensity Quick testing instrument at present.

Two, preparation is installed.Select suitable power system and injection system according to the strength of materials, power system and injection system unit are installed and is fixed on mounting system, thus detector is assembled into one.Then operational power system, produces and stores mechanical injection institute energy requirement, completing preliminary work.
Three, detect.Holding detector makes it perpendicular to leveling plane, and detector is tightly propped up material leveling plane, start power system, storage power is discharged, under the effect of releasing energy, injection system flattens planar impact and a knocking-on round pool to material, is then removed by detector.
Four, calculate.Round pool knocking-on for injection system is cleaned out, then measures round pool diameter with vernier caliper and so on measuring tool, then according to the diameter of round pool with the intensity corresponding relation of expecting of measuring and monitoring the growth of standing timber find out the intensity level of expecting of measuring and monitoring the growth of standing timber.It should be noted that, can in laboratory in advance by the diameter of round pool with the intensity corresponding relation of expecting of measuring and monitoring the growth of standing timber find out and be depicted as and show so that the view of the scene.It should be noted that, when detector operates, injection system gauge head placement direction is different, the diameter of corresponding round pool with measure and monitor the growth of standing timber the intensity corresponding relation of expecting can be different, need to select different mapping tables according to different placement directions.
It is evident that, measuring diameter more intuitively more convenient than fathoming, and spherical crown shape gauge head volume comparatively to survey nail much larger, in testing process, anti-ectocine ability is stronger, to survey data more stable and accurate.And only require when detector involved in the present invention is called for short the strength of materials that detector is perpendicular to leveling plane, the angle of leveling plane is also unrestricted, can be horizontal direction also can be vertical direction, can be more other angles.
In sum, the present invention can realize the technique effect that safe and convenient is quick, all-dimensional multi-angle measures high-water material intensity.
