摘　　要：压水试验是水文地质测试方法之一,是水利水电工程勘察设计的一项重要工作内容。现市场上销售的压水试验装置,都是双回路气压式或水压式栓塞,需要下两套管子,对小口径金刚石钻孔不适用,且操作费时,超过130m以后,双回路水压式栓塞存在胶管放水困难的问题。使用气压式双回路栓塞,存在诸多缺点。为解决上述问题,研发了绳索取芯不起钻进行压水试验技术,有助于绳索取芯技术在水利水电行业的推广。Water pressure test is one of the hydrogeological testing methods and an important part of the survey and design of water conservancy and hydropower engineering.The pressure water testing devices currently sold on the market are dual circuit pneumatic or hydraulic plugs,requiring two sets of pipes to be installed.It is not suitable for small diameter diamond drilling and the operation is time-consuming.When the length exceeds 130m,there is a problem of difficult drainage of the rubber hose in the dual circuit hydraulic plug.Therefore,there are many drawbacks to pneumatic dual circuit embolization.To address the aforementioned issues,a water pressure test technology using rope core extraction without drilling has been developed,which will contribute to the promotion of rope core extraction technology in the water conservancy and hydropower industry.
