钻孔灌注桩施工毕业论文

Abstract
Filling pile in engineering filed by means of mechanical drilling，steel tubesoil compaction or humanmining methods formed in foundation soil pile hole ，and placed inside reforcing cage，perfusion pile，made of concrete and in accordance with different methods and piles into holes and can be divided into driven cast-in-place piles ， bored piles and dig-hole piles etc categories. According to the cast-in-place pile into piles of classification and define a kind of pile type. With the all-round development of our country's transport business, bridge bored piles technology and application also has changed with eachpassing day.
Key words: bored piles，The construction technology ，Control the quality

摘要
摘要
灌注桩是指在工程现场通过机械钻孔、钢管挤土或人力挖掘等手段在地基土 中形成桩孔，并在其内放置钢筋笼、灌注混凝土而做成的桩，依照成孔方法的不 同，灌注桩可分为沉管灌注桩、钻孔灌注桩和挖孔灌注桩等几类。而钻孔灌注桩 是按成桩方法分类而定义的一种桩型。随着我国交通事业的全面发展，桥梁钻孔 灌注桩工艺及应用也发生了日新月异的变化。
In jianglu bridge as an example, this paper discuss the bored piles construction technology and quality control, system elaborated the drilled pile has the construction is convenient, easy to operate, the characteristics of the investment of equipment, this paper introduces the construction technology of bored piles and its attention points, points out that should do well in the preparation work before construction, to ensure the engineering quality and progress.
