Chutes
Push buggies
Buckets handled by cranes
Pneumatically forcing through a hose (shotcrete) (Gunnite)
217
Concrete should be compacted for
-eliminate stone pockets, large air bubbles
-consolidate each layer with one placed earlier
-completely embed reinforcing and fixtures
-bring just enough fine material to the faces and top surfaces to produce desired finish
218
Placing of Concrete
-placed to point where concrete will stay as close as possible
-not in large quantities and allowed to run or worked over large distance
-mortar flows ahead of coarser material results sloping surface
-placed horizontal layers uniform thickness, each layer compacted before the next is placed
-layer must be placed before other layer hardens
219
Maximum volume that can be placed in the bucket without spillage based on a specified angle of repose for the material in the bucket.
Heaped volume

Scaffold Platform Construction Requirements
Space between the platform and uprights not more than 1 inch (2.5 cm) wide. The space must not exceed 9½ inches (24.1 cm) when side brackets or odd-shaped structures result in a wider opening between the platform and the uprights.
221
Maximum Deflection of a platform
not more than 1/60 of the span
222
Each scaffold platform and walkway must be _______ at least wide, guardrails and/or personal fall arrest systems must be used.
18 inches (46 cm)
223
The standard requires employers to protect each employee on a scaffold more than ____________ above a lower level from falling to that lower level.
10 feet (3.1 m)
224
Guardrails are not required, however:
When the front end of all platforms are less than 14 inches (36 cm) from the face of the work.
When outrigger scaffolds are 3 inches (8 cm) or less from the front edge.
When employees are plastering and lathing 18 inches (46 cm) or less from the front edge.
225
must not be used as a toprail or a midrail.
Steel or plastic banding
226
Represents that component of vehicle weight which acts parallel to an inclined surface.
Grade Resistance
227
workers must be protected from cave ins by the use of
Sloping
Benching
Shielding
228
mainly used for deep compaction and literally involves dropping a weight (or pounder) that is suspended from a crane onto the ground.
Dynamic Compaction or Heavy Tamping
229
A very long standing wave on a large but limited body of water generally occurring when a storm dies down after producing a wind tide is called
seiche
230
Waves generated by storms, which is occur outside area of observation
swells
231
an instrument use to measure the intensity of wind
Beuforts scale
232
an open water of navigable depth is called
fairway
233
the difference in height between the mean higher high water and the mean lower low water
Diurnal range
234
the highest tides which occur at intervals of half a lunar month is called
spring tide
235
wave formed by moving ship or boots are called
wakes
236
the ratio of the wave length to its height for ocean waves is between
17 and 33
237
Waves continue to grow after they reach a velocity equal to _____ but at a decreasing rate. Energy losses from friction, transfer of energy into currents and the development of white caps means the wave will not grow until the wave speed reaches the wind speed. The wind speed is 146 kph
48.67
238
the datum line for design of port facilities in accordance with charts, which is being used by the Philippine Ports Authority
MLLW
239
The PPA requires that water level that guarantees about water depth for safety of the ships berthing on a certain ports and harbor below the mean lower low water should be equal to
0.15 - 0.40 m
240
When the lines connecting the earth with the sun and the moon form a right angle that is the moon in her quarters, then the actions of the moon and sun are subtractive, and the lowest tides of the month occur.
Neap tide
241
Owing to retardation of the tidal wave in the ocean by frictional force, as the earth revolves daily around its axis and as the earth revolves daily around its axis and as the tide tends to follow that direction of the moon, the highest tide for each location is not coincident with conjunction and opposition but occurs at some constant time after new and full moon.
age of tide
242
The elements of Berthing Facility are
I. Planned Water Depth
II. Design Water Depth
III. Coping/ Crown Elevation
IV Length of Standard And Approach Part
V. Width and Slope of Apron
243
Generally, the average interval between successive high tides, which is half the time between successive passages of the moon across a given meridian
12 hrs and 25 mins
244
the pressure against a vertical wall due to waves is called
clapotis
245
a change in the dissection of travel of the wave with change in depth of water which distributes wave energy along the seashore unevenly
wave refraction
246
Harbors can be broadly classified as
Natural Harbor
Semi-Natural Harbor
Artificial Harbor
247
Waves formed by gravitational attraction of the moon and sun
tides
248
it prevents you from hitting the ground during the fall
fall arrest system
249
it is the ability of a soil to support the weight of vehicle under repeated traffic
trafficability
250
determines the maximum number of passenger cars that can pass a given point on a lane or roadway during one hour prevailing roadway and traffic conditions
possible capacity
251
means that the utility of any particular trip is partially dependent on the activity it makes possible, and the way in which that activity is valued by the individual
Deprived Utility
