| 中文摘要:辐射井作为城市地下水供水构筑物和盐碱地改良的集水设施，凭借单井出水量大、水质稳定及控制面积大等特点被广泛应用。本文对传统辐射井施工方案进行了调研，并分析总结出传统集水井和辐射孔施工过程中存在施工安全性低、钻进效率慢且钻孔质量差等问题，提出了以旋挖钻进的方式施工辐射井中的集水井，以水平定向钻进的方式施工辐射孔的方案。通过现场实验，发现此方案能有效解决传统方案中存在的问题，进一步研究之后值得推广。 |

| Abstract:Radial collector wells are widely used as the municipal ground water production structure, as well as water intake facilities to improve saline-alkali land due to their characteristics of high water yield per single well, stable water quality and large control area. Investigation of the construction methods of traditional radial collector wells has found some problem, such as low construction safety, low drilling efficiency and poor drilling quality in the construction process of traditional collection shafts and radial laterals. This paper puts forward a solution for drilling of the radial collector well: sinking the collection shaft by auger drilling, and constructing the radial laterals by horizontal directional drilling. Through field trials, it is found that this solution can effectively tackle the problems existing in the traditional method, and it will find wider use with further improvement. |
