提升围堤工程袋装砂成型效率方法探析

Study on Promoting the Construction Effiency of Bagged Sand in Polder Dike Engineering

随着经济的快速发展,为解决土地供需矛盾,近年来一系列促淤圈围工程在上海地区陆续实施,其中围堤工程多采用传统袋装砂斜坡堤结构。内外棱体土方施工进度直接决定龙口合龙的成败,本文以横沙七期工程为例,开展提升袋装砂成型效率研究,分析影响袋装砂施工效率的各种因素,并就要因提出相应的控制措施,为后续类似工程施工提供参考。

With the rapid development of economy, Shanghai government carries out a series of reclamation projects to solve the contradiction between supply and demand of land in recent years. Polder dike engineering mostly uses traditional structure of bagged sand slope embankment. Construction progress of earthwork prism determines the success of dike closure.To promote the construction efficiency of bagged sand, the writer takes Hengsha seventh phase reclamation project for the subject, analyses the influential factors and puts forward corresponding control measures in this paper.The results can provide reference for similar projects.
