Grouting and water stopping method
The embodiment of the invention provides a grouting and water stopping method. The grouting and water stopping method comprises the steps of carrying out air bag plugging on a pipeline to be repaired;pumping and desilting the pipeline to be repaired; striking a grouting pipe into the edges of water leakage holes according to the water leakage condition of water leakage positions, connecting a grouting pipeline, observing the water level condition in the pipeline of the pipeline to be repaired, and if the water level in the pipeline of the pipeline to be repaired exceeds the water leakage position, starting grouting operation; and after grouting operation is completed, observing whether the water leakage holes are filled with the slurry or not, and observing the water leakage condition ofthe water leakage holes. According to the grouting and water stopping method, grouting and water stopping operation is carried out mainly by enabling the water pressure inside and outside the pipelineto be in a balanced state, the situation that a water leakage part is broken under the condition that the external water pressure is large is avoided, and the situation that grouting materials are washed away due to the fact that the water pressure is too large during leakage repairing is avoided.
本公开实施例中提供了一种注浆止水方法，所述注浆止水方法包括如下步骤：对待修复管道进行气囊封堵；对待修复管道进行抽水清淤处理；根据漏水位置的漏水情况在漏水孔边缘打入注浆管并连接好注浆管线，观察待修复管道的管道内的水位情况，若待修复管道的管道内水位超过漏水位置，则开始进行注浆操作；完成注浆操作后，观察漏水孔处浆料是否填满以及观察漏水孔漏水情况。本公开实施例中的注浆止水方法主要通过使管道内外水压处于平衡的状态来进行注浆止水操作，避免了在外部水压大的情况下将漏水部位冲破的情况，以及避免在进行补漏时，水压过大冲走注浆料的情况。
