高压喷射灌浆技术在水利水电施工中的应用

Application of High-Pressure Jet Grouting Technology in Hydraulic and Hydropower Construction

高压喷射灌浆技术作为一种利用高压射流的冲击力破坏被灌土体的灌浆工艺,不仅能够促进砂类土、黏性土、黄土等底层均匀加固,更有利于形成一个防渗板墙,提高水利水电建设工程地基、墙体结构的稳定性。目前,高压喷射灌浆技术在水利水电施工中的应用已经全面展开,但是仍然存在着一些工艺问题亟待解决。对此,特对高压喷射灌浆技术在水利水电施工中的应用问题进行分析,提出对应的策略,从而进一步增强高压喷射灌浆技术的价值作用。

High-pressure jet grouting is a grouting technology which uses the impact force of high-pressure jet to destroy the grouted soil mass.It can not only promote uniform reinforcement of bottom layers such as sand,clay and loess,but also be beneficial to form a cut-off panel wall and improve the stability of foundation and wall structure of hydraulic and hydropower construction project.At present,the application of high-pressure jet grouting technology in hydraulic and hydropower construction has been fully developed,but there are still some technical problems to be solved urgently.Therefore,this paper analyses the application problems of high-pressure jet grouting technology in hydraulic and hydropower construction and puts forward corresponding strategies in order to further enhance the value of high-pressure jet grouting technology.
