Rotary bored pile Explanation: This is the closest term I can find, here are some references: "Rotary Bored Piles Rotary bored piling method refers to the installation of piles using drilling techniques. Bored piles are drilled using buckets and/or augers inside a temporary casing driven in place by vibratory hammers or through twisting in place. The temporary casing maintains the upper soil layers stable especially in water bearing stratum. Depending on the designed toe level of the pile, drilling underneath the casing may take place in stable soils such as rock or cohesive soils." http://www.nsccme.com/rotary-bored.html CIVIL ENGINEER: What are bored cast in-situ concrete piles? https://civiltechnical.blogspot.com/2011/12/what-are-bored-c... Dec 21, 2011 - Design and construction of bored cast in situ piles are done in ... The boreholes are drilled using rotary or percussion type drilling rigs, using . "Rotary Bored Piling Bored piles are often larger diameter than conventional continuous flight auger (CFA) piles and are used to support greater loads, overcome underground obstructions, penetrate ground too hard to bore using a continuous flight auger or create piles with a cut-off level beneath the platform level. Because the rotary bored technique enables the reinforcement to be added into the open bore rather than into the ready poured concrete, as in CFA, it has the distinct advantage of allowing the cage to be the full depth of the pile.

soil displacement piles, bored cast in-situ concrete piles Explanation: https://www.bauer.de/export/shared/documents/pdf/bma/datenbl... On reaching the final depth the displacement tool is extracted and concrete is simultaneously pumped through the hollow drill stem -------------------------------------------------- Note added at 5 hrs (2017-03-08 09:40:30 GMT) -------------------------------------------------- soil displacement piles http://www.farrellinc.com/images/library/pdfs/Farrell_DDP_Fo... -------------------------------------------------- Note added at 5 hrs (2017-03-08 09:41:55 GMT) -------------------------------------------------- 2. Full displacement piles (FDP) FDP are a type of reinforced concrete pile that are built in situ. This technology combines the advantages of driven piles (displacement piles) and bored piles (piles without displacement). Despite being executed in situ, along with bored piles, they are classified as displacement piles due to the fact that, throughout its execution, it exists the soil consolidation around the pile, as a result of an horizontal displacement imposed 2 by the drilling equipment. This compaction intends to improve the soil characteristics thus increasing the available area at the time of the loading application. This technique uses a specific drilling equipment which is inserted in the soil by virtue of the application of a torsional movement, applied in the auger rod, and a downward thrust. The main difference between this technique and the remaining techniques is the drilling tool configuration that causes an horizontal displacement during the drilling process due to a zone with a greater diameter. According to Fiorotto et al (2008), this technique's most frequent diameter is 620 mm, being also possible the existence of 360, 440 and 510 mm. Since this technique is applied to different soil types, being the drills also adjustable, it is possible to obtain a greater equipment performance. https://fenix.tecnico.ulisboa.pt/downloadFile/56334509041360... |
