Claims
- 1. A process for stabilizing a structure embedded in an earth formation, comprising:
- disposing a solidifiable liquid resin composition between at least an external portion of the structure and the surrounding earth formation, said composition containing 10-50%v polyglycidyl ether of 2,2-bis(4-hydroxyphenol)propane, 10-88%v ethylacetate, 0-78%v butyloxitol, 2-20%v diethylenetriamine and 0-78%v xylene; and
- solidifying the resin composition in intimate and static contact with both the structure and the formation, whereby the solidified resin is bonded to both the structure and the formation.
- 2. The method of claim 1 wherein said composition includes 0-15%v dimethylaminomethylphenol.
- 3. A method for installing a hollow pile in an earth formation, comprising the following steps:
- driving said pile into an earth formation, said earth formation tighly engaging the outer surface of said pile along a section thereof when said driving is completed;
- placing a closing plate at the bottom inner part of the pile;
- creating at least one perforation in at least one of (a) the closing plate and (b) a section of the wall near the bottom end of the pile;
- disposing said perforated section of said pile within a weak or unconsolidated portion of said earth formation;
- displacing through said pile and said perforation a liquid thermosetting resin-forming composition;
- permeating said portion of said formation with said liquid composition in a radially extensive zone that is continuous from within the piling out into said portion; and
- solidifying said liquid composition into the radially extensive zone to form a consolidated mass integrally comprising said premeated zone and said pile, characterized in that the liquid thermosetting resin-forming composition contains 10-50%v polyglycidyl ether of 2,2-bis(4-hydroxyphenol)propane, 10-88%v ethylacetate, 0-78%v butyloxithol, 2-20%v diethylenetriamine and 0-78%v xylene.
- 4. A method for installing a hollow pile in an earth formation, comprising the following steps:
- driving said pile into an earth formation, said earth formation tightly engaging the outer surface of said pile along a section thereof when said driving is completed;
- placing a cement plug at the bottom inner part of the pile;
- creating at least one perforation in at least one of (a) the cement plug and (b) a section of the wall near the bottom end of the pile;
- disposing said perforated section of said pile within a weak or unconsolidated portion of said earth formation;
- displacing through said pile and said perforation a liquid thermosetting resin-forming composition;
- permeating said portion of said formation with said liquid composition in a radially extensive zone that is continuous from within the piling out into said portion; and
- solidifying said liquid composition into the radially extensive zone to form a consolidated mass integrally comprising said premeated zone and said pile, characterized in that the liquid thermosetting resin-forming composition contains 10-50%v polyglycidyl ether of 2,2-bis(4-hydroxyphenol)propane, 10-88%v ethylacetate, 0-78%v butyloxithol, 2-20%v diethylenetriamine and 0-78%v xylene.
- 5. The method of any one of claims 3 and 4 wherein at least one of the second and third steps precedes the first step.
