| 中文摘要: |
| 水文地质钻探工作是一项复杂的系统性工程,包含诸多施工工序,各工序的施工质量影响整个项目的实施。本文探讨了水文地质钻孔关键工序在施工过程中需要重点注意的事项,并以太原市小店区内实施的SZK1水文地质钻孔为例,介绍了该钻孔施工过程中为保证钻孔质量,在取芯、扩孔、成井等关键工序采取的一系列保证工程质量的施工措施,指出了防止涌砂以及出水量减少的预防措施,以期对类似项目的实施有一定的借鉴和指导意义。 |
| 英文摘要: |
| Hydrogeological drilling is a complex and systematic project, which includes many construction procedures. The construction quality of each procedure affects the implementation of the whole project. This paper discusses the key points in the construction process of hydrogeological drilling, and takes the SZK1 hydrogeological drilling in Xiaodian District of Taiyuan City as an example, introduces a series of construction measures taken in the key processes of coring, reaming, well completion to ensure the drilling quality, the preventive measures to prevent sand inflow and reduce water output are pointed out, In order to have a certain reference and guiding significance for the implementation of similar projects. |
