20 Persons required to enter excavations over 4 feet in depth, stairways, ramps or ladders are required and lateral travel to these is not to exceed 25 feet Also, walkways or bridges are required with standard guardrail for persons required to cross over the excavation ACCESS AND TRENCHES
21 Vertical and Lateral Pressures LOOK FOR CRACKS AND THE BOTTOM EDGE OF THE DITCH!
22 A: CRACKS OCCUR 1/3 TO 2/3 BACK FROM EXCAVATION, USUALLY VERTICAL & MAY BE 1/2 THE DEPTH OF THE TRENCH. B. 1ST. FAILURE DUE TO WEIGHT OF COLUMN OF SOIL AT BOTTOM. C. 2ND FAILURE DUE TO LESS LATERAL FORCES HOLDING COLUMN OF SOIL. D. ULTIMATE CAVE IN DUE TO GREATER FORCES BOTH LATERALLY AND NO SHEAR FORCES HOLDING DUE TO CRACKS. E. SHOWS FIRST, SECOND, AND THRID FAILURE ZONES. THESE ARE NOT THE ONLY REASON FOR FAILURES, ALSO WEATHER, WATER, VIBRATION, OTHER LOADS ON SOIL. TYPICAL TRENCH FAILURE You ll find this On Page #5!!
23 SOIL CLASSIFICATION SYSTEM WHAT IS THE ONLY PURPOSE TO CLASSIFY SOIL TYPE? To determine the protection to be used for employees working in the excavation! Mandatory Knowledge for Competent Person
24 SOIL CLASSIFICATION SYSTEM A METHOD OF CATEGORIZING SOIL AND ROCK DEPOSITS IN A HIERARCHY OF: STABLE ROCK and THREE TYPES! TYPE A TYPE B TYPE C DECREASING ORDER OF STABILITY
25 TRENCH & EXCAVATIONS MAY BE A CONFINED SPACE UNDERGROUND UTILITY VAULTS, TUNNELS, PIPELINES, AND OPEN TOP SPACES MORE THAT 4 FEET IN DEPTH SUCH AS PITS, TUBS, VAULTS, AND VESSELS THE ABOVE IS QUOTED AS PART OF THE OSHA DEFINITION OF A CONFINED SPACE
26 MAXIMUM ALLOWABLE SLOPE THE STEEPEST INCLINE OF AN EXCAVATION FACE THAT IS ACCEPTABLE FOR THE MOST FAVORABLE SITE CONDITIONS AS PROTECTION AGAINST A CAVE IN. EXPRESSED AS THE RATIO OF HORIZONTAL DISTANCE TO VERTICAL RISE. (H:V)
27 MOST STABLE: CLAY, SILT CLAY, & HARDPAN (RESISTS PENETRATION) SUCH AS CALICHES HAS A COMPRESSIVE STRENGTH OF 1.5 TSF OR GREATER TYPE A SOIL IS NOT FISSURED, SUBJECT TO VIBRATION, PREVIOUSLY BEEN DISTURBED, OR HAS SEEPING WATER. TYPE A
28 TYPE B SOIL CLASSIFICATION COHESIVE SOIL WITH A UNCONFINED COMPRESSIVE STRENGTH <.5 TSF BUT LESS THAN 1.5 TSF, GRANULAR COHESION LESS SOILS INCLUDING ANGULAR GRAVEL, SILT, SILT LOAM, AND SANDY LOAM, SOIL THAT HAS BEEN PREVIOUSLY DISTURBED (EXCEPT TYPE C ) SOIL THAT MEETS TYPE A REQUIREMENTS EXCEPT IS FISSURED OR SUBJECT TO VIBRATION AND DRY ROCK THAT IS UNSTABLE.
29 TYPE C SOIL CLASSIFICATION COHESIVE SOIL WITH AN UNCONFINED COMPRESSIVE STRENGTH OF.5 TSF OR LESS GRANULAR SOILS INCLUDING GRAVEL, SAND, LOAMY SAND, SUBMERGED SOIL OR SOIL FROM WHICH WATER IS FREELY SEEPING, AND SUBMERGED ROCK THAT IS NOT STABLE.
30 HOW COMPETENT PERSON CLASSIFIES SOIL TYPE. TWO FIELD TESTS: ONE VISUAL AND ONE MANUAL TEST 1. VISUAL ANALYSIS (OBSERVATION) 2. MANUAL ANALYSIS Why does he Classify the soil? TO DETERMINE STABILITY!
31 SOIL CONTENTS CLAY SILT SAND THE DEGREE OF COHESIVENESS & PLASTICITY DEPEND ON THE AMOUNT OF ALL THREE OF PLUS WATER. Soooo.the major factor in the stability is the water content!
32 SOIL VISUAL TEST IS EXCAVATED SOIL IN CLUMPS? YES.IT IS COHESIVE NO.. NOT COHESIVE & BREAKS UP EASILY IS THE SOIL FISSURED?
33 MANUAL SOIL TESTS/ THREE TYPES 1. WET MANUAL TEST 2. DRY STRENGTH TEST 3. THUMB PENETRATION TEST
34 WET MANUAL TEST WITH WET FINGERS WORK SOIL BETWEEN THEM. CLAY WILL FORM A SLICK PASTE CLUMPS FALL APART IN GRAINS IT IS GRANULAR NOT COHESIVE.
35 DRY STRENGTH TEST CRUMBLE SAMPLE IN HAND CLAY WILL NOT CRUMBLE INTO GRAINS BUT SMALL CHUNKS GRANULAR WILL CRUMBLE INTO GRAINS.IE: NOT COHESIVE
36 UNCONFINED COMPRESSIVE STRENGTH TESTS POCKET PENETROMETER TEST
37 UNCONFINED COMPRESSIVE STRENGTH TESTS SHEARVANE TEST USED FOR SATURATED SOILS RESULTS TONS PER SQ. FOOT (TSF)
39 REVIEW QUESTIONS? 1. What designated person is required for Excavation/Trenching Operations? 2. What is the sole purpose of classifying the type of soil for excavation/trenching? 3. How does the designated person determine the soil type classification?
41 SLOPING & BENCHING BASED ON SOIL CLASSIFICATION TYPE A SOIL IS NOT FISSURED, NOT SUBJECT TO VIBRATION, NOT PREVIOUSLY BEEN DISTURBED. IS COHESIVE, WITH UNCONFINED COMPRESSIVE STRENGTH OF 1.5 TONS PER SQUARE FT OR GREATER THE EXCLUSIONS FOR TYPE A GENERALLY ELIMINATE IT FROM MOST CONSTRUCTION SITUATIONS SLOPE FOR TYPE A IS 1/2 : 1
42 TYPE B AND C SOIL SLOPING OPTIONS MAY 2007
43 MULTIPLE BENCHING
44 QUESTION? WHAT IS THE REASON ON ALL THE DIAGRAMS FOR SLOPING & BENCHING FOR ANY TYPE OF SOIL, THERE IS A FIGURE OF 20 FOOT MAX. DEPTH SHOWN?
45 ANSWER!!!!! THE SLOPING & BENCHING SYSTEMS SHALL BE DESIGNED BY A REGISTERED PROFESSIONAL ENGINEER (PE) AT LEAST ONE COPY OF THE DESIGN SHALL BE MAINTAINED AT THE JOB SITE DURING CONSTRUCTION. 25.C.01c REMEMBER: For all Hydraulic shoring, and Trench Boxes, the tabulated data must be on the site.
