在水利工程中,用作防渗的技术有很多,而目前使用最广泛的是高压喷射灌浆技术,该技术大多使用在一些松散地层中,与其余防渗技术相比优势显著。其通过高压射流对原有的松散地层进行冲击、破坏,然后将混合水泥浆灌入,在水泥浆中掺入一些易凝结的化学物质,最终使得在地下形成凝结体,以达到加固地基进行防渗的作用。根据某工程施工实例,对高压喷射灌浆技术施工概念、施工优势、施工质量控制及施工过程中常见问题进行叙述,以期为相关工作者提供一些借鉴。
In water conservancy projects, there are many technologies for seepage prevention. At present, the most widely used is high-pressure jet grouting technology, which is mostly used in some loose formations and has obvious advantages over other seepage control technologies. It is through the high pressure jet to the original loose strata impact, destruction, and then poured into the mixed slurry in the cement slurry incorporation of some easy to condensation of chemicals, eventually making the formation of underground condensation, in order to achieve reinforcement of the foundation to prevent Permeate the role. According to the construction example of a project, the construction concept, construction advantages, construction quality control and common problems in the construction process of high-pressure jet grouting technology are described in order to provide some references for the relevant workers.
