When a cylindrical hole is bored on the ground and then concrete is poured into the hole to make a pile that is called bored cast in situ pile Now let's see The Specification Of A Bored Cast In Situ Concrete Pile You'll get a drawing something like the image below Get Price
Borehole Diameter How Large is Large Enough? Introduction In order to address the topic of appropriate borehole diameter we begin by emphasizing the importance of perspective What does perspective have to do with appropriate borehole diameter? Well actually quite a bit This memorandum is written from the perspective of a well designer in 2005 However one would get a much different view Get Price
As I was told piling contractor wanted to bore a 1000mm diameter 12m depth hole for tremie pipe and hopper washing I'm was curious whether to bore a hole or is there another better alternative EDIT what I asking is what's the common way to clean tremie pipe after concreting Get Price

A tremie is a watertight pipe usually of about 250mm inside diameter (150 to 300 mm) with a conical hopper at its upper end above the water level It may have a loose plug or a valve at the bottom end A tremie is used to pour concrete underwater in a way that avoids washout of cement from the mix due to turbulent water contact with the concrete while it is flowing Get Price
Grout should always be introduced into the drill hole through a tremie pipe exiting at the bottom of the hole Construction techniques for bored piling in sand using polymer fluids This paper is concerned with the use of polymer fluids for the construction of bored piles in silty fine sand a situation which has steel cage and buildup of tremie pipes Get Price
17/11/2009All pile shall then be concreted by using the 'tremie' method Concrete of higher slump (=175mm+25mm) shall be used for 'tremie' method The self-compacting mixed concrete will be discharged through a tremie pipe which is lowered centrally to the bottom of the bored hole prior to filling it with concrete Concrete level of the borehole Get Price
Piles can either be driven into the ground (driven piles) or be installed in a predrilled hole (bored piles or drilled shafts) The construction of bore cast in situ concrete pile consists of 4 primary phases 1 Pile boring 2 Reinforcement cage lowering 3 Flushing 4 Pile concreting Now we will discuss each phase one by one 1 Pile [] Get Price
