Atomization, Impact A type of fuel atomization used in a deisel hammer in which the raw fuel injected and trapped between the ram and the anvil is atomized by impact of the ram on the impact block. Airlift A pressure method of cleaning loose material out of an open-ended cased pile, caisson or cofferdam cell.
Auger Flights Sections of a continuous flight auger “quick-coupled” together to form a continuous auger. It is the least value determined from the structural capacity of the pile as a structural member; the allowable load based on penetration;the capacity demonstrated by load test divided by a safety factor; or basic maximum load prescribed by the applicable or design standard or code. The auger is withdrawn at a steady rate as the grout is placed. Liquid Limit and Plastic Limit; organic impurities; compaction standard Proctor method, compaction modified Proctor method, and unconfined compressive strength.
Anchor Bolt A bolt anchored to rock or concrete to hold down structures or other objects. The abutment of an arch is sometimes called a bench wall. A fine deposit of earth, sand, gravel and other transported materials which have been washed in and deposited by rivers, floods or other causes to rest on land, not permanently submerged.
Method by inductively coupled plasma emission spectrometry in soils: Arch Web A type of sheet pile. Structural fabrication or casting placed in a helmet to adjust to a different type or size of pile. Can be cut to any length needed for making long bolts.
Sieving method; ten per cent fines value TFV ; determination of shell content.
The d23 of a pile hammer seated directly under the ram which transmits the blow of the ram to the pile or to the drive cap also called the Impact Block. A hand operated soil sampler. A helically shaped corkscrew-like tool asm a power driving head on top and cutting head on s423 bottom designed to bore holes in the earth by drilling, either with or without the supplementary use of water. A type of fuel atomization used in a deisel hammer in which the raw fuel injected and trapped between the ram and the anvil is atomized by impact of the ram on the impact block.
Auger Grout Pile Pile formed by boring a hole with an auger and placing pressurized grout in the hole through the hollow center of the auger. Also called the Deadman. NCh NCh 8.
Piles driven near test pile to anchol jacking beam thereto also called Reaction 4d23. Also called Drilled Pier, Drilled Shaft. Allowable Pile Load The load permitted on any vertical or batter pile applied concentrically along its axis. A long-handled cutting tool with a thin arched blade that is perpendicular to the handle. Augered Pile Concrete pile cast-in-place in an augered hole, which may be belled at the bottom.
Proctor modified; Specific gravity of dd423. Ash content; e423 matter; fixed Carbon; inherent moisture; moisture; hardgrove index; chlorine; and fluorine. A proprietary Augered Pile. Percentage of shells in coarse; sand equivalent value of soils and fine aggregate. A person learning a trade working in the field with a journeyman and attending classes in an approved apprenticeship program. Piles driven behind retaining walls, and beyond the area where soil may slip, to which tie-back rods or cables are attached.
Used for rough dressing timber. Driving a pile at an angle from the vertical where the bottom of the pile is inclined toward the crane.
Liquid Limit of Soils & Plastic Limit to ASTM D423 & D424
High strength grout is forced down the center of a flight atsm to form a shaft as the auger is with drawn. A structure supporting the shore end of a bridge; a supporting wall carrying the end of a bridge or span and generally sustaining the pressure of the abutting earth.
Subsurface water which qstm sufficient pressure to raise the water in wells above the groundwater table. The hammer normally will have a time delay between impact and combustion.
It is shaped like an arch.
ICE Glossary of Terms
Water boind to soil particles because of the attraction between electrical charges existing on soil partical surface and dipole water molecules. The water content where the soil behavior changes from the liquid to the plastic state is the liquid limit; from the plastic to the semi-solid state is the plastic limit and from the semi-solid state to the solid state is the shrinkage limit.
Dry maximum density; Dry minimum density; Determination fine material less 0. Flakiness index;; particle shape Section Average volumetric coefficient of gravel; and Extraction and preparation of stone samples. Round steel rod threaded from one end to the other. 4d23 method of test see: Elongation ast, of coarse aggregate; testing aggregates Part Flexion traction; fine material less than 0. Wstm where soil is dry and hole will stand open.
Primary standards writing body for pressure treatment of wood, including pressure-treated timber piling.
The Liguid limit, plastic limit, and shrinkage limit for soil. Atomization, Injection A type of fuel atomization used in a deisel hammer in which the fuel is atomized by an injector.
Sieve tests; determination of particle shape. Granulometry of stone; Real and net density and water absorption of gravel; Real and net density and water absorption of sands; Determination of Gaps; Determination of crumbly particles; Determination. See Continuous Flight Auger.
Wear resistance of the aggregates of sizes smaller than Air is directed upward out of the larger pipe; this upward flow tends to lift material in the pile.
