When Sandblasting pipe In case of joint leakage, first identify the leakage part, and then inject grouting fluid into the sand blasting pipe at the leakage part. During grouting, use the grouting pump to inject grouting fluid into the distributor. The grouting fluid flows into a grouting channel of the sand blasting pipe through the distributor. During grouting, seal the other leading out end of the sand blasting pipe, and the pressure of the grouting channel into which the grouting fluid is injected increases, Due to the elasticity of the foam strip, the foam strip is squeezed and deformed during grouting, and the grouting fluid can be sprayed out of the grouting hole, filled to the leakage part of the joint, and terminated its leakage.

After grouting, it is necessary to flush the grouting channel with water injection. During flushing, open the sealed outlet end of the sandblasting pipe. During the process of water injection, water flows in from one outlet end of the sandblasting pipe and flows out from the other outlet end of the sandblasting pipe. The flushing of the grouting channel is completed to prevent the grouting fluid from silting up in the grouting channel and blocking the grouting channel, The sand blasting pipe can be repeatedly grouted. At the same time, one end of the sand blasting pipe is sealed during grouting.

Therefore, in the process of grouting, the pressure in the grouting channel increases continuously, the foam strip is squeezed and deformed, and the grouting fluid is ejected from the grouting hole. When flushing the pipeline Sandblasting pipe Both ends of the grouting tube are open. Water flows in from one end of the sandblasting tube and flows out from the other end of the sandblasting tube. The pressure in the grouting channel is low. The foam tape restores to the original state and blocks the grouting holes to prevent water from overflowing from the sandblasting tube.
