The upper part of the photo is a cut through the center of the shaft parallel to the shaft axis. The cracks appear to correspond to th e path of the tremie pipe.
Concreting in Pile Foundation (BNBC2006)In case of providing concrete in water free condition in borehole, the slump should be 150 mm. In case of tremie concreting slumps of concrete are kept within (125150) mm. Dear reader there has some requirements of cement content and strength of concrete for different piling conditions and way to concreting, which we will learn in our next post.

Lecture 3 Drilled Shaft Design and Constructionconfinement reinforcement, to allow for better concrete consolidation during placement. Concrete mix design and workability shall be consistent for tremie or pump placement. In particular, the concrete slump should be 8 inches ±1 inch for tremie or slurry construction and 7 inches ±1 inch for all other conditions.
Admixtures in Pile Concreting: A Case Studytermed as "bored piles" and "driven piles" respectively. Castinsitu concrete piles may be cast in metal shells, which may remain permanently in place. However, other types of castinsitu concrete piles, plain or reinforced, cased or uncased, may be used if the site conditions permit.
Tremie tube Kajima Kensetsu Kabushiki KaishaDec 12, 1978· In the case of a plunger type prior art tremie tube, the tube is sunk to the bottom of the body of water, with its lower end kept open to avoid the buoyancy problem. Thereafter, a plug or plunger is loosely inserted into the top end of the tremie tube and fresh concrete is fed onto the plunger.
Chapter 11 Foundation Support Wisconsin Department of ...The primary functions of a deep foundation are: • To transmit the load of the structure through a stratum of poor bearing capacity to one of adequate bearing capacity. • To eliminate objectionable settlement. • To transfer loads from a structure through erodible soil in a scour zone to stable, underlying strata.
