Method for constructing stabilized construction wall in unstable footing

Abstract

Abstract A METHOD OF PROVIDING STABILIZATION FOR A CONSTRUCTION WALL DURING CONSTRUCTION IS AN UNSTABLE FOOTING INCLUDES THE FORMATION OF A BASIN ABOVE THE PRE-EXISTING SURFACE LEVEL OF A PROPOSED CONSTRUCTION ZONE OR SITE. THE BASIN IS USED TO RECEIVE FLUID THEREIN TO PROVIDE INCREASED HYDROSTATIC PRESSURE, ACTING ON THE WALL FROM INSIDE THE CONSTRUCTION SITE TO PROVIDE PRESSURE WITHIN THE SITE TO A DEGREE APPROXIMATING THE COUNTERVAILING PRESSURES ACTING ON THE CONSTRUCTION WALL FROM OUTSIDE THE SITE. THEN, WHILE MAINTAINING THE HYDROSTATIC PRESSURE, THE SOIL MATERIALS WITHIN THE SITE ARE REMOVED BY EXCAVATING DOWN TO A PREDETERMINED LEVEL AND REPLACED (WHILE STILL MAINTAINING THE HYDROSTATIC PRESSURE) WITH A STABILIZING FILL MATERIAL OF GREATER STRENGTH THAN THE UNSTABLE MATERIAL REMOVED FROM THE SITE. THEREAFTER, THE HYDROSTATIC PRESSURE CAN BE RELIEVED AND PREPARATION OF THE SITE CONTINUED. THE WALL STRUCTURE FORMED WILL ULTIMATELY BE CHARACTERIZED BY AN UNSTABLE FOOTING MATERIAL ON ONE SIDE OF THE WALL AT THE LOWER END THEREOF, A MAT OF STABLE FOOTING MATERIAL ON THE OTHER SIDE OF THE WALL, AND A MAT OF CONCRETE SUPERIMPOSED UPON THE MAT OF STABILIZED FOOTING MATERIAL SO THAT THE CONCRETE MAT CAN COUNTERACT LATERALLY ACTING FORCES PRESSING AGAINST THE OUTSIDE OF THE WALL.
