Abstract

The invention discloses a measuring device and a measuring method for density degree of ball arranging type large particle diameter windrow. The measuring device comprises measuring balls, a photoelectric elevation controller, a photoelectric measuring bar, a photoelectric flat ball ruler and photoelectric ball counting equipment. The method comprises the following steps: measuring the average relative elevation of the large particle diameter windrow on a measuring pit top surface by the photoelectric elevation controller and the photoelectric measuring bar on a large particle diameter windrow measuring surface; digging out the large particle diameter windrow according to the designed depth and diameter; filling with the measuring balls, enabling the measuring balls to be clung to rugged pit walls and a pit bottom in the measuring pit, and leveling the measuring balls in the rugged pit according to the measured average relative elevation of the measuring pit top surface; counting the number of the measuring balls in the measuring pit by the photoelectric ball counting equipment, and meanwhile absorbing all measuring balls in the measuring pit; measuring data such as the ball number and the weight of the large particle diameter windrow according to the depth and the diameter of the dug measuring pit. The measuring device has the characteristics of high precision, good accuracy, simplicity and convenience in operation, quickness and real-time performance in measuring and the like, and provides new instrument equipment for measuring the density degree of the large particle diameter windrow.

Description

technical field [0001] The invention relates to a device and method for testing the compactness of large particle size stockpiles, in particular to a ball-placed large particle size stockpile compactness test device and a test method thereof. Background technique [0002] At present, water bag method, settlement method, etc. are often used to test the compactness of large-size stockpiles such as rockfill dams and rockfill subgrades, but this kind of equipment has low precision, inconvenient operation, and cannot output test data in real time. deficiencies. Contents of the invention [0003] Aiming at the shortcomings of the existing equipment and methods for testing the density of large-size stockpiles such as rockfill dams and rockfill subgrades, the present invention proposes a ball-type large-size stockpile density test device and its testing method, which can The density test of large particle size stockpiles is carried out at the test site, and the test data is outpu...
