The object of the present invention is achieved like this:
The on-the-spot test test method that grouting automatic recording instrument record material accuracy judges, feature is: concrete steps are as follows:
A, first check and be used for the tap water meter whether tap water meter of test and measuring is through measurement verification unit assay approval, whether grouting pump is be intact equipment on inspection; Then the electromagnetic flowmeter of grouting automatic recording instrument being connected on one with the tap water meter through measurement verification unit assay approval is in the milk on pipeline, the water inlet end of grouting pipeline connects a grout-stirring barrel by grouting pump, the water side of grouting pipeline connects a water butt, is connected to into slurry end pressure table and slurry output end tensimeter at the grouting water inlet end of pipeline and water side;
B, startup grouting pump supply water, and check whether the junction at electromagnetic flowmeter and the tap water meter two ends that grouting pipeline connects seals water-tight; If seal intact water-tight, then testing experiment work can be carried out;
C, grouting pump supply water to grouting pipeline under the pressure of setting, when grouting pump water supply normal operation, and after electromagnetic flowmeter and tap water meter work well, regulate the water flow by-pass valve control behind tap water meter water side by testing experiment requirement, make water flow meet testing experiment requirement;
After D, the test of beginning flow rate test, will according to testing experiment work division, carry out reading and the writing task of test data, after testing experiment terminates, the testing crew that takes one's test is signed exact p-value test data sheet data then and there, testing experiment will record the start time of testing experiment and the initial flow numerical value of tap water meter then and there, collects the water flowed out from pipeline on rear side of tap water meter water side with water butt simultaneously;
E, after testing experiment terminates, according to testing experiment work division, following three work to be carried out by testing experiment technician: one is measure the water yield that water butt collects, and calculates the water yield value of collecting in the unit interval in the testing experiment period; Two is calculate the water yield value by tap water meter in the testing experiment period, and calculates the water yield value by tap water meter in the unit interval in the testing experiment period; Three is in printing test pilot time slot, the water yield value by electromagnetic flowmeter of grouting automatic recording instrument record and the water yield value by electromagnetic flowmeter in the unit interval in the testing experiment period;
The water yield value that F, testing experiment technician will collect in the unit interval within the testing experiment period with water butt is radix, the amount of water per time unit value within the testing experiment period by comparison test tap water meter and electromagnetic flowmeter two kinds of discharge metering methods, judges the accuracy of grouting automatic recording instrument record material.
The present invention is in Hydraulic and Hydro-Power Engineering grouting project construction preliminary work stage and work progress, is tested the accuracy verifying grouting automatic recording instrument record material by on-the-spot test.
The present invention has following characteristics:
1, make use of the existing preparation of construction in working-yard and device: the enforcement of testing experiment method of the present invention, do not need to increase equipment or device in addition, utilize the existing preparation of construction in working-yard and device, just can complete testing experiment work.
2, testing experiment is simple to operate: testing experiment of the present invention is simple to operate, and do not need special operating personnel's operation, as long as under relevant personnel's witness of the unit such as management, design, grouting construction operating personnel just can complete testing experiment operation element.
3, testing experiment data accuracy is high: the water yield that the present invention collects within the testing experiment period can accurate-metering, and the water yield value therefore in the water butt unit interval is also accurately; It is qualified that tap water meter is examined and determine through metrological service before use, and the water yield value of therefore tap water meter metering is also effective.Therefore compare with the record material value of grouting automatic recording instrument and the record value of aforementioned two kinds of metering methods, just accurately can judge the accuracy of the data of grouting automatic recording instrument record.
4, improve the probability record material accuracy of grouting automatic recording instrument being judged to contrast test test, be conducive to improving grouting works construction quality.
