预制内扣式内螺纹抗拔空心方桩的设计

The Design of Antiplucking Hollow Square Pile in Prefabricated Internal Thread

近几年来,预应力混凝土内扣式内螺纹抗拔桩在工程实践中得到了广泛应用。原省标图集《预应力混凝土抗拔空心方桩(一)内扣式机械连接》(苏G/T24-2013)于2016年底作废后,结合工程实践和广泛征求意见,经过对2013版省标图集内容进行调整,改版为《预应力混凝土内扣式内螺纹抗拔空心方桩》企业技术标准设计图集,并于2017年3月1日起实施。文章给出抗拔桩的设计选用方法,以供设计和施工人员合理有效地参照与使用新出版的图集。

In recent years, the prestressed concrete internal thread anti-pulling pile has been widely used in engineering practice. Former provincial plot set ＂of prestressed concrete pile hollow party（a） mechanical connection＂ button（G/T24 su-2013） after the void at the end of 2016, combining with engineering practice and consultation, through adjusting the content of the 2013 provincial plot set, redesign for the prestressed concrete button within internal thread pulling hollow square pile ＂enterprise technology standard atlas, and on March 1, 2017. In this paper, the design and selection of anti-pilings are presented in this paper to provide a reasonable and effective reference for the design and construction personnel and the use of newly published atlas.
