城镇雨污分流非开挖工程中的工程勘察内容和要求

Task and Requirement of Engineering Investigation of Trenchless Technology in Urban Diversion of Rain and Sewage

摘要:

论述在城镇雨污分流工程中采用非开挖技术需要工程勘察的内容和要求。针对非开挖技术特点，与常规市政工程勘察的对比分析，得出采用非开挖技术施工所需要的工程勘察特性。结合廊坊市雨污分流非开挖试验段工程，分析了前期工程勘察对后期非开挖工程施工的影响，具体分析工程地质勘察和施工区域地下管线探测特殊性对非开挖工程设计、施工的意义。最后从雨污分流非开挖试验段工程结论出发，总结采用非开挖技术施工进行工程勘察的常规性内容，为以后类似工程采用非开挖技术施工提供参考。

Abstract:

The paper discussed the requirement and significance of engineering investigation for the application of trenchless technology in the diversion of rain and sewage of urban drainage system. According to the analysis on comparison between specification of trenchless technology and routine municipal engineering investigation, engineering investigation characteristics of trenchless technology construction was learned. With the trial section project of the diversion of rain and sewage drainage system of Langfang city, analysis was made on the influence of earlier investigation upon late trenchless construction, and the importance to trenchless engineering design and construction by engineering geological investigation and underground pipe detection was clarified. In the end, the paper summed up the routine work of engineering investigation for trenchless technology construction to give the reference in the diversion of rain and sewage to more urban drainage systems.
