Underground pipeline sedimentation repair high polymer membrane bag grouting method
The invention relates to an underground pipeline sedimentation repair high polymer membrane bag grouting method. The method comprises the following steps: (1) detecting a sunken pipe segment, and determining a grouting scheme; (2) drilling a membrane bag accommodating hole; (3) placing a membrane bag; (4) injecting a high polymer material into the membrane bag; (5) lifting the pipe segment; (6) filling a gapped region and reinforcing a soft soil layer. The high polymer material is a non-water-reaction bi-component high polymer material. The method has the advantages of rapidness, minimal invasiveness, light mass, high toughness, economical efficiency, durability and the like, lifting repair of an underground sedimentation pipe segment can be rapidly realized, and a novel advanced, efficient, economical and practical scheme is provided for underground pipeline sedimentation repair. The method is successfully applied to a plurality of underground pipeline lifting projects, and has great economic and social benefits and wide development and application prospects.
