TRENCHLESS SYSTEM FOR THE SUBSURFACE DELIVERY OF A POLYMER-BASED MESH

摘要

A trenchless system for subsurface delivery of a polymer-based mesh (75) to protect an underground structure is provided. The system includes: a body (100) for moving above the ground and over the underground structure while the system delivers the mesh (75) below the ground; a polymer mesh supply (120) coupled to the body and configured to supply the mesh during the moving of the body; and a ripper assembly (130) coupled to the body and configured to move through the ground in response to the moving of the body without digging a trench and while receiving and delivering the supplied mesh below the ground and above the underground structure to protect the underground structure. In an embodiment, the polymer mesh supply includes a polymer mesh spool configured to rotate during the moving of the body in order to supply the mesh. A method of trenchless subsurface delivery of the mesh is also provided.
