摘要
为了解决传统施工质量控制技术造成的渗水面积过大的问题,研究一种水利水电工程高压旋喷灌浆施工质量控制技术。综合影响喷射直径的主要因素,估算出高压旋喷灌浆的喷射直径,依据估算出的喷射直径,设计施工过程中支护桩桩长的防渗形式,形成一个五面止水结构,控制工程的渗水面积,采用交叉折线形连接旋喷与摆喷,设置孔距和布置形式,实现水利水电工程高压旋喷灌浆施工质量的控制。实验结果表明,在相同的施工面积下,与传统施工质量控制技术相比,水利水电工程高压旋喷灌浆施工质量控制技术造成的渗水面积最小,施工质量控制效果最佳。
In order to solve the problem of large seepage area caused by traditional construction quality control technology,a high-pressure rotary jet grouting construction quality control technology is studied.Based on the main factors affecting the jet diameter,the jet diameter of high-pressure rotary jet grouting is estimated.According to the estimated jet diameter,the anti-seepage form of supporting pile length in the design and construction process is formed into a five sided water stop structure to control the water seepage area of the project.The rotary jet and swing jet are connected by cross fold lines,and the hole spacing and layout form are set to realize high-pressure rotary jet grouting in water conservancy and hydropower projects quality control of grouting construction.The experimental results show that under the same construction area,compared with the traditional construction quality control technology,the construction quality control technology of high-pressure rotary jet grouting in water conservancy and hydropower projects has the smallest seepage area and the best construction quality control effect.
