波浪型预制桩护岸在河道治理中的应用

Application of Wavy Precast Pile Revetment in River Regulation

摘要:

以德州市站前沟河道治理工程为例,阐述了波浪型预制桩的结构设计过程和施工注意事项,分析了该护岸在城市河道的施工中出现的问题及解决办法,包括护岸与城市复杂地下管线和既有建筑物衔接的设计、在复杂地层中施工时的加固处理、桩后反滤层新材料的应用、预制桩顶栏杆的选择等,可为预制桩的广泛应用提供借鉴。

Abstract:

Taking the Zhan Qiangou River Regulation Project in Dezhou Municipality as an example, this paper illustrates the structural design process and key construction points of wavy precast piles. Problems encountered during construction of this type of revetment in urban rivers and corresponding solutions are analyzed, including design for connection between revetments and complex urban underground pipelines as well as existing buildings, reinforcement measures for construction in complex strata, application of new materials for the back-pile filter layer, and selection of railings atop precast piles. It can provide reference for the wide application of precast piles.
