Result in the sake of compactness hole grouting

A, not the incentive reason caused by grouting process there are two: (continued 1) Total number of slurry are prepared ahead of time is not enough. ( 2) Industrial equipment to produce common failure, without reserve backup device. 2, had to interrupt the damage analysis of grouting process, need to secondary grouting, such as from the original grouting mouth immediately carry out grouting, see is pulp outlet slurry to be felt hole grouting to fill her already, turn off the mouth, in fact when the channel running memory of the gas is not discharged, residual to produce a large section of the category of the clearance in the hole, the hole grouting compactness, pests are very easy to permeate the line caused by steel bar rusting. Three, prevention countermeasures of grouting is not continuous problem prevention countermeasures: ( 1) Appropriate estimate slurry use, want to consider to the specific engineering construction in the port, secrete the place such as pipes, pulp outlet slurry loss. ( 2) Watch for machinery equipment maintenance and management, and has set aside machine equipment. ( 3) Once appear, such as end grouting, should be moved around grouting mouth, mouth in a second grouting inner insert hole plasma volume, all the first grouting mouth into two slurry and grouting in the middle of the air discharged completely, to ensure that grouting tightly.
