Description

Intelligence grouting system

(1) technical field: the utility model relates to a kind of grouting detection register system with Based Intelligent Control.For the engineering metering in the grouting works of power station and quality monitoring.Genus capacity, flow measurement class (G01F).

(2) background technology:

Grouting works is generally used in the dam construction of power station.Grouting is that the embankment, ground etc. pointing to power station dam pours into the material such as cement, mortar, to strengthen fastness, improves barrier performance.Therefore, grouting quality will determine the total quality of power station dam.

Fig. 1 is shown in the grouting detection register system general arrangement in existing power station: in order to detect pour in grout hole 6n slurry flow, density, pressure, the numerical value such as to lift and to go forward side by side line item, in grouting pipeline 2n, establish cement slurry preparing barrel 1n in turn, enter to starch flow sensor 3n, density sensor 4n, grouting pump 5n, grout hole 6n, lift sensor 7n, pressure transducer 8n, then overfall flow sensor 13n sends back to cement slurry preparing barrel.Five sensors are connected with grouting automatic recording instrument 9n sensor connector at a distance respectively by each sensor electrical signal wire 3.1n, 4.1n, 7.1n, 8.1n, 13.1n, each sensor is detected data and delivers to registering instrument, grouting construction record sheet is printed again with printer 10n, for owner's viewing, make it to understand and grasp grouting construction quality.Between pressure transducer and overfall flow sensor, pipeline is provided with high-voltage electric valve 12n.Grouting automatic recording instrument can establish audible-visual annunciator 11n on demand.

Relating to cement grout specific gravity test in cement slurry preparing barrel 1n in existing above-mentioned grouting detection register system is adopt manually to carry out: manually the cement grout configured in cement slurry preparing barrel (also claiming tank diameter) is sampled one piece of proportion being placed on fixed volume deserves to be called weighed amount, just can obtain the proportion of this groove cement grout.This manual measurement has following problem: 1) artificial sample is time-consuming.2) proportion claims difficult in maintenance, after weighing, must clean, airing at every turn, extremely bothers.3) cement grout collection is interrupted, and primary sample replaces this groove cement grout proportion, is unfavorable for ensureing grouting quality.

In existing above-mentioned grouting detection register system relate to cement slurry preparing barrel 1n, there are the following problems for the raw-material stock mixing system of slurries: in existing cement slurry preparing barrel, the preparation of slurries is manually carry out entirely.According to the requirement of grouting works quality, different geologic structures, position, the grout hole degree of depth all need the cement grout of variable concentrations, method manually with slurry needs 2 to 3 people's whole process on duty, and process need with slurry is constantly checked concentration of slurry and whether is reached requirement, cause that efficiency is low, cost is high, labour intensity is large, time-consumingly takes a lot of work, and proportion speed rate can not be guaranteed.
