Research Of Offshore Anchorage Pile Construction And Test Technology Application

Anchorage pile is one type of pile foundation,when the local bedrock surface is relatively high,the loading-bearing capacity can meet the design requirement by hamm er driven the pile,but pulling resistance can not.Regarding this issue,the general wa y is add socketed pile or pour concrete into the pile to improve the pulling resistance of pile.But along with the progress of technology,specially application of high-stren gth anchor rod,using anchor rod improve pulling resistance,it can save construction c ost and shorten construction period.This technology has already been applied in many field such as offshore structure,bridge structure and so on,and also offshore oil dril ling platform,tower foundation of electricity and communication which requires high pulling resistance,there are good economic benefits from this technology.Taking some project construction as an example,this document is mainly to study the construction procedure of anchorage pile,clarify the key point of construction and improve the co nstruction quality.According to analysis of anchorage pile application in some project construction,this document summarizes the key point of anchorage pile construction procedure,collect general issues and solving methods.Meanwhile according to pulling resistance test of anchorage pile,gets aware of bearing status in anchorage pile,summarizes the suitable embedded depth of anchorage pile in slight-weathered rock.Mainly content includes : First describe the structure and theory of anchor pile,Summarize the construction procedure and key point of anchor pile,Clarify the test method of pulling resistance of anchorage pile with some example,Analyze and summarize the reasonable embedded depth of the high-strengt anchor rod.Along with society progress,the anchorage pile will also be adopted generally because of geological conditions.this document summarize and clarify and key point of anchorage pile construction procedure,having an important guide on anchorage pile construction by taking example of project construction.
