主要介绍了哈尔滨市城堤截渗工程采用高压喷射灌浆工程,重点阐述了哈尔滨市城堤截渗工程设计参数指标,高压喷射灌浆工程采取的技术规范。明确了此项工程的质量评定标准,详细地介绍了每一项设计指标所对应的施工质量指标,单位工程、分部工程、单元工程的质量评定标准,明确了这项工程的施工质量合格标准、施工质量优良标准。根据此项工程的实际情况确定了质量检测方法,采取开挖检测、钻孔取样检测和围井检测相结合的方法,对检测结果进行了分析。从哈尔滨市城堤高压喷射灌浆截渗工程的实践中,补充和完善了所采用的技术规范,总结了高压喷射灌浆截渗工程的实用范围。由这项工程可以看出,哈尔滨市城堤截渗工程设计参数指标过于保守,质量评定标准过高。通过对这项工程的剖析,进一步完善了高压喷射灌浆截渗工程的施工规范和设计参数,摸索出了高压喷射灌浆截渗工程的质量评定指标。希望为今后高压喷射灌浆截渗工程提供参考。
Mainly introduces the high-pressure jetting grouting project of embankment seepage in Harbin, embodies the design parameters of embankment seepage in Harbin, and the technical specifications of high-pressure jet grouting. Clarified the project quality assessment standards, a detailed introduction of each design index corresponding to the construction quality indicators, unit project, branch project, unit project quality assessment standards, a clear construction of the project quality standards Construction quality standards. According to the actual situation of the project to determine the quality of testing methods to take excavation testing, drilling sampling and well testing combined detection method, the test results were analyzed. From the practice of high-pressure jet grouting seepage engineering in the embankment of Harbin City, the technical specifications adopted are supplemented and improved, and the practical range of high-pressure jet grouting engineering is summarized. It can be seen from this project that the design parameters of embankment seepage in Harbin are too conservative and the quality assessment standards are too high. Through the analysis of this project, the construction specifications and design parameters of high pressure jet grouting cutoff engineering are further perfected, and the quality assessment indexes of high pressure jet grouting cutoff seepage are explored. Hope for future high-pressure jet grouting impervious engineering provide a reference.
