引汉济渭工程隧洞围岩压水试验装置研发及应用

Development and application of water pressure test device for tunnel surrounding rock of the water diversion from the Han to the Wei River

结合引汉济渭工程隧洞线路长大、地质条件复杂等特点,研制轻便、可靠、灵活、自动的钻孔压水试验装置,该套装置具有压水管路损失不修正、测试数据自动化、试验精度高等特点,能很好地揭示围岩强、中、弱透水性的演化规律,为隧洞渗控方案设计提供了科学依据,具有显著的现场实用价值和推广应用价值。

The lightweight,reliable,flexible and automatic drilling pressure test device was developed in the water diversion from the Han to the Wei River for its long line and complicated geological conditions. The device consists. Has the advantages of no loss of water pressure pipeline,automatic test data,high test precision,etc.. The device revealed the strong,medium and weak permeability of surrounding rock,provided a scientific basis for the design of tunnel seepage control scheme,and had significant practical value and application value.
