马尔代夫柴油机发电及海水淡化项目强渗水性珊瑚砂地区钢板桩支护施工

The Construction of Steel Sheet Pile Support in the Area of StrongPermeable Coralline Sand of Maldives Diesel Engine PowerGeneration and Desalination Project

马尔代夫柴油机发电及海水淡化项目主要地质条件为强渗水性的珊瑚砂地质,其中海水取水泵房地下结构部分深度超过6 m,为马尔代夫深度最深的构筑物。采用400型拉森钢板桩支护进行该地下结构的施工。本文重点探讨了钢板桩施工、排水技术及计算措施。

The main geological condition of Maldives diesel engine power generation and desalination project is the coral sand geology with strong water permeability,in which the underground structure of seawater intake pump house is more than 6m deep,which is the deepest structure in Maldives.The construction of the underground structure is successfully carried out by using 400 Larsen steel sheet pile support.This paper focuses on the construction of steel sheet pile and drainage technology and calculation measures.
