specific Embodiment approach
[0064] As a specific implementation of the slurry consolidation state detection method provided by the present invention, step S3 specifically includes:
[0065] S31: The consolidation detector 3 emits longitudinal waves multiple times at the same time interval, and the path of the longitudinal waves traverses the slurry;
[0066] S32: Record the velocity of each longitudinal wave passing through the slurry, and formulate a time-velocity curve according to each record;
[0067] S33: Observe the interval with the highest rate of change of the longitudinal wave velocity in the curve, which is the initial setting time of the slurry.
[0068] By adjusting the time interval between the longitudinal waves emitted by the consolidation detector 3, the accuracy of the measured initial setting time can be adjusted; for example: the initial setting time measured by emitting a longitudinal wave every 5 minutes, and the final measured initial setting time by emitting a longitudinal wave ev...

Abstract
The invention provides slurry consolidation state detection equipment and a slurry consolidation state detection method, and belongs to the technical field of geological grouting. The slurry consolidation state detection equipment comprises an outer cylinder, an inner cylinder and a consolidation detector, wherein the outer cylinder is connected with a water pressuring pump, and the bottom part ofthe outer cylinder is provided with a drain port; the inner barrel is arranged in an inner cavity of the outer barrel; a first cavity used for accommodating water is formed between the inner cylinderand the outer cylinder, the first cavity is communicated with the water pressuring pump, a second cavity used for accommodating slurry is formed in the inner cylinder, a water seepage material used for allowing the slurry to seep into the first cavity is arranged on the side wall of the inner cylinder, and the second cavity is communicated with a high-pressure grouting pump; and the consolidationdetector is used for emitting longitudinal waves into the second cavity and measuring a propagation speed of the longitudinal waves in the slurry, so that the consolidation state of the slurry is obtained. The slurry consolidation state detection equipment and the slurry consolidation state detection method provided by the invention can simulate the water seepage condition of the slurry under high pressure in the field working condition, improve the accuracy and reduce the labor intensity.
Description
technical field [0001] The invention belongs to the technical field of geological grouting, and more specifically relates to a detection device and a detection method for the consolidation state of slurry. Background technique [0002] Geological grouting technology is a method of injecting different ratios of grout into geological bodies under high pressure to repair damaged geological bodies and reduce the permeability of aquifers. It can effectively solve the contradiction between the regional groundwater environment and the safe exploitation of mineral deposit resources. Its application is becoming more and more more extensive. [0003] With the increasing demand for mineral resources and the continuous increase of mining intensity in my country, a series of environmental, water resource protection and safety issues brought about by drainage in the mining process have become increasingly prominent. The mine curtain grouting technology can effectively solve the contradic...
