Construction method for carrying out high-pressure rotary jet grouting based on slurry return data
The invention discloses a construction method for carrying out high-pressure jet grouting based on slurry return data, and belongs to the technical field of constructional engineering construction. Equipment required for realizing the method comprises a cement slurry viscometer, a cement slurry stirring system, a returned slurry flowmeter, a returned slurry drainage groove, a filter pressing system, a data analysis system, a rotary jet grouting drilling machine, a geological drilling machine, a rotary jet grouting drilling machine console, a rotary jet grouting pump and a high-pressure pump. The key construction steps are as follows: carrying out guide hole construction; installing the returned slurry flowmeter and the cement slurry viscometer; starting rotary jet grouting construction; dynamically adjusting construction parameters; carrying out rotary jet grouting slurry returning treatment; and finishing construction of rotary jet grouting piles. According to the method, the returnedslurry viscosity change is caused by different mixing degrees of cement and soil in returned slurry, the rotary jet grouting quality is judged by virtue of the viscosity parameter, and the construction parameters are adjusted, so that the mechanization and intelligence of construction are realized, the labor force is liberated, and the construction cost is reduced.
本发明公开了一种基于返浆数据进行高压旋喷的施工方法，属于建筑工程施工技术领域，实现上述方法需要具备的设备包括水泥浆粘度计、水泥浆搅拌系统、返浆流量计、返浆引流槽、压滤系统、数据分析系统、旋喷钻机、地质钻机、旋喷钻机控制台、旋喷泵、高压泵；关键施工步骤如下：引孔施工；安装返浆流量计及水泥浆粘度计；开始旋喷施工；施工参数动态调整；旋喷返浆处理；完成旋喷桩施工。本发明通过返浆中水泥和土体的混合程度不同而引起的返浆粘度变化，进而依靠粘度参数判定旋喷的质量，进而调整施工参数，实现了施工机械化、智能化，解放了劳动力，降低施工成本。
