Description
Technical field
The present invention relates to a kind of experimental provision, relate in particular to a kind of low-noise pollution-free full-automatic concrete anti-abrasion tester.
Background technology
Concrete material is the most large, the purposes of a consumption building structural materials the most widely up to now, to the evaluation of concrete performance, except the mechanical property of the workability of its mix, maturing, more need consider the endurance quality of concrete material.Wherein, the impact-resisting wear-resisting performance of the concrete material of structure positions such as the spillwag chute in the hydraulic structure, draft tube, flood discharging tunnel, scouring sluice and concrete pavement material is to estimate the important technology index of these position concrete structure durabilities.
In the Hydraulic and Hydro-Power Engineering field, China just issued the concrete for hydraulic structure test method as far back as 1962, had wherein just recommended the anti-ring method that contains sand current scour test of concrete; Issued " concrete for hydraulic structure testing regulations " SD105-82 through being revised in nineteen eighty-two for the first time subsequently; After carrying out the revision second time in 1996; Issued new " concrete for hydraulic structure testing regulations " DL/T5150-2001 in calendar year 2001; Be developed at present, the evaluation of concrete impact-resistant anti-wear performance is generalized to 3 methods, being respectively that concrete is anti-contains sand current scour test (ring method); Concrete anti-abrasion test (steel ball method under water) and concrete anti-abrasion test (wind sand marksmanship) are to adapt to the impact-resisting wear-resisting concrete in different current eroding velocities, the different impact-resisting wear-resisting performance evaluation of destroying under the media type effect.In addition; In 2005; Receive high-velocity flow to dash phenomenons such as mill, cavitation corrosion to outlet structure escape works in China's Hydraulic and Hydro-Power Engineering and issued " hydraulic structure anti-impact mill cavitation prevention concrete technology rules " DL/T 5207-2005, it also is above-mentioned 3 kinds of test methods of recommending to concrete impact-resisting wear-resisting method of evaluating performance.Although China has obtained rich experience to the research of concrete for hydraulic structure impact-resisting wear-resisting performance and the exploration of evaluation method in decades; But planning to build and building along with a collection of high-head power station of China; Outlet structure escape works earial drainage flow velocitys such as its flood discharging tunnel, spillwag chute mostly surpass 40m/s, and destruction is extremely serious down containing effects such as the sand high-velocity flow washes away, wearing and tearing on the outlet structure escape works surface.Impact-resisting wear-resisting materials such as concrete are in the existing a great difference of failure mechanism that contains under the effect of sand high-velocity flow; Impact-resisting wear-resisting materials such as understanding concrete are significant for the impact-resisting wear-resisting performance that materials such as estimating concrete is containing under the effect of sand high-velocity flow in the mechanism that contains under the effects such as the sand high-velocity flow washes away, wearing and tearing, and for further research high-impact abrasion-proof concrete and impact-resisting wear-resisting protective materials provide technical support.Although " concrete for hydraulic structure testing regulations " DL/T 5150-2001 and " hydraulic structure anti-impact mill cavitation prevention concrete technology rules " DL/T 5207-2005 have recommended 3 kinds of test methods of estimating the concrete impact-resistant anti-wear performances: ring method, steel ball method and wind sand marksmanship under water; But greater than the containing for the sand current of 40m/s, the correlation test equipment that these 3 kinds of methods of present domestic employing make an experiment all can't reach the required flow velocity requirement of test for flow velocity; " hydraulic structure anti-impact mill cavitation prevention concrete technology standard " DL/T 5207-2005 also points out: " for the anti scuffing problem of flow velocity more than or equal to the outlet structure escape works of 40m/s, should specialise." this has wherein also comprised the deficiency that aspect testing equipment, exists at present.At first, previous impact-resisting wear-resisting testing equipment can't reach more than the 40m/s, can't satisfy the impact-resisting wear-resisting material test requirement that contains under the sand high-velocity flow condition; Secondly, what traditional ring method and steel ball method under water all can't be adjusted medium dashes the angle lap degree, although and traditional wind sand rifle equipment can be adjusted towards the angle lap degree, grind speed but still restrict to dash in it; The 3rd, there is the problem that noise is big, dust pollution is serious in traditional wind sand rifle testing equipment, and is relatively poor as far as testing crew experimental enviroment and condition, is difficult for promoting the use of.
