SUP&LAYNG WSEL LAYER — SUPPLY AND LAYING WSEL LAYER: WSEL (WEDGE SHEAR ELEMENT LAYER) OF STONE: (UNDER RCC RETAINING WALL FOUNDATIONS AND BELOW BULLETS). SUPPLYING AND LAYING OF WSEL LAYER IN DENSE TO VERY DENSE CONDITION USING 80 MM TO 300 MM SIZED BASALT OR GRANITE STONES WITH INTERSTICES PACKED WITH SPALLS AND STONE DUST AND WATERING COMPACTING WITH VIBRO-ROLLER TO ACHIEVE THE DESIRED COMPACTION AS PER THE DETAILED PROCEDURE OF CONSTRUCTION AND COMPACTION OF WSEL GIVEN IN THE TENDER SPECIFICATIONS, FILLING IN LAYERS, INCLUDING THE COST OF ALL LABOUR, MATERIAL, EQUIPMENT, LEAD, LIFT ETC., ALL COMPLETE AS PER TECHNICAL SPECIFICATIONS AND AS DIRECTED BY THE ENGINEER-IN-CHARGE. ON TOP OF CLEANED HARD SURFACE PLACE COBBLE SIZE STONES OF 80 MM TO 300 MM THICKNESS IN 300 MM LOOSE THICK LAYER AND FILL THE GAP BETWEEN STONES WITH MURRUM SOILS AND COVER STONES TOP WITH MURRUM SOILS TO OBTAIN 450 MM LOOSE THICK LAYER OF WSELS-1. SPRINKLE 5 LITERS OF WATER PER SQ.M AREA ON TOP OF MURRUM SOILS, ALLOW THE WATER TO SOAK AND THEN ROLL ON TOP OF MURRUM SOILS USING VIBRATORY ROLLER OF 10T SELF-WEIGHT. THE TIME OF ROLLING IS ONE HOUR PER 100SQ.M AREA TO BE ROLLED. FOR EXAMPLE-TOTAL AREA EXCAVATED =2000 SQ.M. THEN TOTAL TIME OF ROLLING=2000 X 1/100=20 HOURS. METHOD OF WSEL: I) TAKE INITIALLY THE RLS OF EXCAVATED AND CLEANED GL AT 3M CENTER TO CENTER SQUARE GRIDS JUNCTIONS. GRID JUNCTION POINTS ARE MARKED WITH LIME POWDER. DETERMINE THE AVERAGE RL. II) PLACE FIRST LAYER OF WSELS AS STATED ABOVE OF ABOUT 45 CMS LOOSE THICKNESS. SPRINKLE WATER OVER IT AT THE RATE OF 5 LITERS PER SQ.M AREA. ALLOW WATER TO SOAK IN THE LAYER AND IN THE GROUND. III)ALLOW VIBRATORY ROLLER TO MOVE ON THE TOP OF MURRUM SOIL FOR TOTAL TIME PERIOD AS GIVEN ABOVE. AFTER ROLLING FOR 3 HOURS, AGAIN MARK THE GRID JUNCTION POINTS WITH LIME POWDER. JUNCTION POINTS SHALL BE AT SAME POINT WHERE INITIAL LEVELS WERE TAKEN. TAKE LEVELS AT THE JUNCTION POINTS. DETERMINE THE AVERAGE RL. THE DIFFERENCE IN AVERAGE RLS WILL GIVE THE AVERAGE SETTLEMENT OF GROUND IN 3 HOURS OF ROLLING. IV) REPEAT THE OBSERVATIONS AT EVERY 3 HOURS OF ROLLING AND NOTE THE AVERAGE RLS AT NEWLY MARKED JUNCTION POINTS. VI) THUS AFTER 20 HOURS OF ROLLING, TOTAL 8 READINGS OF AVERAGE RLS WILL BE AVAILABLE WITH INITIAL AVERAGE RL WITHOUT ROLLING. VII) PLOT THE GRAPH OF TIME IN 3 HOURS ON X AXIS AND SETTLEMENT OF GROUND AFTER EVERY 3 HOURS OF ROLLING ON–VE Y AXIS. IF GRAPH IS BECOMING NEARLY HORIZONTAL IN SHAPE INDICATING THE SETTLEMENT IS NOT OCCURRING. THIS CONFIRMS THAT COMPACTION IS SATISFACTORY. THEN PLACE SECOND LAYER AS STATED ABOVE. NO. OF HRS OF ROLLING MAY INCREASE TILL SETTLEMENT IS NOT OCCURRING.
