About this file

Written by GovTribe AI · Feb 11, 2025

This file contains engineering drawings and specifications for a repair project at Marine Corps Air Station Cherry Point, NC to address an infiltration problem in Lift Station B3862. The drawings include a cover sheet with location/vicinity maps, existing conditions plans of a rifle range area, and detailed repair plans for a wet well.

The repair work focuses on fixing groundwater infiltration occurring at a joint between concrete pipe sections in the wet well. The drawings specify a detailed repair procedure using hydrophobic polyurethane chemical grout to be injected through a specific hole pattern. Key technical requirements include drilling 4 holes at 45-degree angles in a 6" x 6" pattern, using pressure injection packers, and applying polyurethane resin that reacts with water to form a water-tight foam seal. The work location is precisely identified within the base complex, with multiple views showing the rifle range infrastructure and wet well location. A pump station schedule is included with technical specifications for the equipment.

INFILTRATION REPAIR PROCEDURE

AutoCAD SHX Text

1. WET WELL IS CONSIDERED A CONFINED SPACE. CONFINED SPACE SAFETY MEASURES SHALL BE TAKEN.WET WELL IS CONSIDERED A CONFINED SPACE. CONFINED SPACE SAFETY MEASURES SHALL BE TAKEN.

AutoCAD SHX Text

2. INFILTRATION OF GROUND WATER IS OCCURING IN ONE LOACTION AT A JOINT BETWEEN 2 SECTIONS OF CONCRETE PIPE, 5 FT DIA.

AutoCAD SHX Text THE LEAK IS UNDER PRESSURE FROM A WATER HEAD DRIVING THE SEEPAGE FROM THE GROUND WATER.

AutoCAD SHX Text

3. REPAIR SHALL BE MADE BY INJECTING A HYDROPHOBIC POLYURETHANE CHEMICAL GROUT (PRODUCT: MOUNTAIN GROUT FLEXIBLE

AutoCAD SHX Text MANUFACTURED BY GREEN MOUNTAIN INTERNATIONAL, INC. 235 PIDGEON ST., WAYNESVILLE, NC 28786 PHONE: 800-942-5151 OR DESIGN APPROVED EQUAL).

AutoCAD SHX Text

4. PREPARATION: THE SURFACES OF WALL TO BE TREATED SHALL BE CLEARED OF ALL DEBRIS FOR OPEN ACCESS AND FOR MONITORING GROUT TRAVEL.

AutoCAD SHX Text

5. THE INFILTRATION LEAK IS LOCATED APPROXIMATELY 8'-4" BELOW GRADE AT A PRECAST PIPE JOINT.

AutoCAD SHX Text

6. DRILL 4 HOLES USING A HAMMER DRILL IN A STITCHING PATTERN AT A 45 DEGREE ANGLE TO INTERSECT THE CRACK AT THE MIDWAY POINT. THE DRILL BIT

AutoCAD SHX Text SHOULD BE THE SAME SIZE AS THE DIAMETER OF THE INJECTION PACKER OF CHOICE. SPACING FOR THE INJECTION PACKERS SHALL BE 6."

AutoCAD SHX Text

7. FLUSH BORE HOLES WITH WATER TO REMOVE CONCRETE DUST AND ENSURE THE ENTIRE AREA TO BE GROUTED IS WET.

AutoCAD SHX Text

8. PLACE HIGH PRESSURE INJECTION PACKERS, " MECHANICAL PACKERS INTO THE HOLES.12" MECHANICAL PACKERS INTO THE HOLES.

AutoCAD SHX Text

9. PUMP POLYURETHANE RESIN UNTIL IT IS SEEN ON THE CRACK FACE, THEN THE INSTALLER MOVES TO THE NEXT BORE HOLE AND REPEATS THE PROCESS.

AutoCAD SHX Text THE POLYURETHANE RESIN REACTS WITH THE WATER IN THE CRACK TO FORM A FLEXIBLE, WATER TIGHT FOAM. INSTALLERS WILL SEE THE FOAM FORMING

AutoCAD SHX Text

IN A MATTER OF MINUTES AND THE FOAM IS FULLY CURED IN APPROXIMATELY 24 HOURS.

AutoCAD SHX Text

10. REMOVE PACKERS, BORE HOLES SHALL BE COVERED WITH MORTAR PATCHES TO PROVIDE A SMOOTH FINISH.
