| titleOfInvention | Construction method for sand blowing and filling between main pipeline and sleeve |
| abstract | The invention discloses a construction method for sand-blasting filling between a main pipeline and a sleeve, and relates to the technical field of municipal pipeline sleeve internal filling. The invention uses the sludge pump to blow the sand-water mixture into the pipe during sand blowing, thereby avoiding dust raising on the construction site and protecting the quality of the surrounding air. The sand blowing pipe plugging method has the advantages that the sand blowing pipe plugging risk can be effectively reduced, the construction investment is reduced, meanwhile, part of pipe fittings can be repeatedly utilized in construction, and the construction concept of energy conservation and environmental protection is fully embodied. |
