水电工程水泥灌浆智能控制方法与系统

Intelligent grouting control method and system for hydropower engineering

水泥灌浆是水电工程基础加固和防渗的重要措施。面向水泥灌浆核心工艺过程控制,基于"全面感知、真实分析、实时控制"的闭环智能控制理论,本文提出了三区五阶段P-Q-C-t联动智能灌浆控制方法,通过灌浆压力P、注入率Q、浆液密度C、岩体抬动值ΔH、浆液温度T及灌浆历时t的实时联动智能控制,实现了正常灌浆和特殊情况灌浆一体化智能识别和控制。研发了智能灌浆单元机iGC和智能灌浆管理云平台iGM组成的智能灌浆系统,实现了水泥灌浆一键式闭环智能控制。在乌东德、白鹤滩等水电站的固结灌浆和高压帷幕灌浆工程中应用显示,该方法与系统提高了水泥灌浆工程的施工质量,具有较高的推广和应用价值。

Cement grouting is an important measure for foundation reinforcement and anti-seepage in hydropower projects. Based on the intelligent closed-loop control theory of 'full perception,real analysis and real-time control',this study proposed a 3-zone,5-stage and P-Q-C-t coordinated real-time control method. Through real-time coordinated intelligent control of the grouting pressure P,the absorption rate Q,the slurry density C,the rock mass uplifting value ΔH,slurry temperature T and grouting duration t,the integration intelligent identification and control of grouting under normal and special circumstances are realized.This study also developed an intelligent grouting system composed of intelligent grouting cell(iGC) and intelligent grouting management cloud platform iGM,which realized one-key closed-loop intelligent control on cement grouting process. The system has been fully applied in the consolidation and high-pressure curtain grouting at the Wudongde and Baihetan hydropower stations. The application ensured the construction quality of cement grouting at dam site,and have high popularization and application value in similar projects.
