Problems solved by technology

2) The existing slurry mixing method has low efficiency, high labor cost, inaccurate mixing ratio, high labor intensity, time-consuming and labor-intensive
3) The existing grouting pumps output high pressure and constant power, which leads to energy waste, and manual operation of high pressure and high pressure valves is unsafe and easy to cause casualties
4) The traditional grouting process is all manually operated, which is not only inefficient, but also easily leads to human cheating, tampering with grouting data, and affecting the quality of grouting

Abstract

An intelligent grouting system is provided with a single chip microcomputer, a keyboard and a display. Pipelines provided with magnetic valves, sensors or electronic scales are inserted into a grout production barrel, wherein the pipelines are respectively loaded with water, cement powder, sand, a chemical additive, dense grout and so on therein; the proportioning and consumption of grout is controlled through programming, thus a grout proportioning efficiency is high, proportioning is accurate, and labor intensity is low. A frequency converter provided with a communication interface is added to a drive motor of a grouting pump, an input end of the single chip microcomputer is connected with a pressure sensor, an output end of the single chip microcomputer is connected with a high pressure valve and an alarm device; the power of the drive motor and the pressures of the pipelines are controllable, thereby saving electric energy; operating personnel are far away from the high-pressure pipes, thus security is achieved. A tension sensor of which an output end is connected with the single chip microcomputer is fixed over the grout production barrel, a metal weight immersed in cement grout is hanged on a lower end of the tension sensor; the single chip microcomputer continuously measures and displays the proportion, and adjusts the grout concentration in real time to ensure grouting quality, the frequency of cleaning is low. Through adoption of the intelligent grouting system, only grouting parameters need to be manually inputted, the subsequent operations such as grout proportioning and grouting are all automatically performed by the system, thereby saving time and labor. The intelligent grouting system is used for grouting construction of a hydropower station, especially at the places such as side slope and dam foundation.

Description

[0001] (1) Technical field: the present invention relates to a kind of grouting detection recording system with intelligent control. It is used for engineering measurement and quality control in hydropower station grouting engineering. It belongs to capacity and flow measurement (G01F). [0002] (two) background technology: [0003] Grouting works are generally used in power station dam construction. Grouting refers to pouring cement, mortar and other substances into the embankment and foundation of the dam of the power station to strengthen the firmness and improve the anti-seepage performance. Therefore, the quality of grouting will determine the overall quality of the power station dam. [0004] The general layout of the grouting detection and recording system of the existing hydropower station figure 1 : In order to detect and record values ​​such as the flow rate, density, pressure, lift, etc. of the grout poured into the grouting hole 6n, a grouting barrel 1n, a grouti...
