摘　　要：HDPE缠绕结构壁管(B型)管道系统(简称塑管系统)已成功应用在吹砂填海地区,解决了吹砂填海地区软土地基的不均匀沉降,以及海水具有较强腐蚀性的问题。填补了塑管系统在吹砂填海地区应用的空白。本文介绍了塑管系统在吹砂填海地区的施工流程及控制要点,对管道地基换填和施工关键点进行了总结,保证了塑管系统的变形率满足技术要求。Pipeline system of HDPE wall pipe with winding structure(type B)(Plastic Piping System for short)has been successfully applied in blown sand reclamation area,which solved the problems of uneven settlement of soft soil foundation and the strong corrosive effect such as seawater in such area.This Plastic Piping System fills in gaps of plastic piping system s application in blown sand reclamation area.This paper introduces the construction process and control points of the plastic piping system construction in blown sand reclamation area and summarizes the key points of pipe foundation replacement and construction,which could ensure that the deformation rate of plastic piping system meets technical requirements.
