Example Embodiment

[0028] see figure 1 , The intelligent stepless grouting implementation method of this embodiment, first of all, this grouting method is implemented in the existing grouting circuit, and the grouting circuit at least includes: the slurry making barrel 1 is connected to the grouting pump from the grouting outlet 1F from the bottom of the pipeline 2 in sequence 3. Slurry inlet flow sensor 5, grouting hole 6, orifice pressure sensor 7, lift sensor 8, return slurry flow sensor 9, pressure regulating valve 10, density sensor return slurry density barrel 4. Finally, the slurry is connected to the upper inlet Barrel; forms an existing basic grouting circulation loop that makes the grout flow. The slurry 1s prepared from the original slurry 1o and the clean water 1w in the pulping barrel 1 is discharged from the slurrying outlet 1F to the grouting hole 6, and the remaining recirculation is returned to the pulping barrel 1 from the returning slurry density barrel 4.

Abstract

The invention provides an intelligent stepless proportioning implementation method. High and low capacitance pressure sensors are installed in a pulping barrel in a grouting circuit, slurry and watersupply valves are installed on raw slurry and clear water inlet pipes, a micro controller is used to obtain a measured proportioning density and volume. A main control program for the real-time monitoring of a proportioning density is used, and with a program (time-based interval volumetric injection method), the obtainment of any volume of raw slurry or clear water with an allowable error range is achieved. The shortening of a water injection time process is also used to overcome the problem of the increase of a proportioning in a time slice method. The problems of unstable quality, a long time of technician training, high cost, easy falsification and the damage to project quality of traditional artificial proportioning are solved, tests prove that a measured slurry density is in a rangeof +/-0.03 g/cm3 of a set slurry density with the proportioning of the invention, setting parameters can be followed well, the method has strong anti-disturbance performance and can be well adapted toon-site proportioning requirements. Under the constraints of many factors of a proportioning and grouting system, the precise program control of the stepless proportioning is realized. The method canbe used in intelligent grouting engineering of hydropower stations.

Description

(1) Technical field: [0001] The invention provides a method for realizing intelligent stepless grouting, and relates to a computer programming control method for a grouting unit machine system. It is used for engineering measurement and quality control in hydropower station grouting engineering. It belongs to capacity and flow measurement (G01F). (two) background technology: [0002] The slurry mixing process is the process of reconfiguring the raw cement slurry with a density of 1.82g / cc and water into a cement slurry with a certain density. In the traditional pulp mixing process, the pulping station first sends the raw pulp with a concentration of 1.82g / cc to the storage tank of the grouting face, and then the on-site workers put a certain amount of raw pulp and a certain amount of raw pulp from the storage tank based on personal experience. Put a certain amount of clear water into the grout mixing tank to make grout that meets the density required for grouting. It can ...
