Abstract
Corrugated metal pipe repair system and method, an embodiment including the securing of one or more sheets to the corrugated pipe and over a damaged portion of the pipe including voids, the delivering of glass particles into the voids and possibly also cavities in ground adjacent to the corrugated metal pipe, and the delivering of a polymer that expands to fill at least a portion of the voids and possibly also a portion of the cavities not filled by the glass particles.
Claims22
A method of repairing a corrugated metal pipe, comprising:
- positioning one or more sheets against the corrugated metal pipe over a damaged portion of the corrugated pipe, the damaged portion comprising one or more voids;
- securing the one or more sheets to the corrugated metal pipe and over the damaged portion of the corrugated metal pipe;
- delivering glass particles into the one or more voids;
- and delivering a polymer that expands to fill at least a portion of the one or more voids;
- wherein the glass particles are propelled in a dry state with a blasting machine into the one or more voids through a nozzle in fluid communication with one or more holes in the one or more sheets.
A method of repairing a corrugated metal pipe, comprising:
- positioning one or more flexible sheets each including one or more holes against the corrugated pipe over a damaged portion of the corrugated metal pipe, the damaged portion comprising one or more voids;
- holding the one or more sheets over the damaged portion of the corrugated pipe with a hydraulic jack;
- fastening the one or more sheets to the corrugated metal pipe using a powder-actuated tool;
- delivering glass particles that include less than one percent free silica into the one or more voids and further into one or more cavities in ground adjacent to the corrugated metal pipe by propelling, through at least one of the one or more holes and under the one or more one or more sheets, using a sandblaster, the glass particles;
- and delivering a polymer through at least one of the one or more holes and under the one or more sheets, the polymer expanding to fill at least a portion of both the one or more voids and the one or more cavities.
