摘要
介绍了9 m和12 m长拉森III型和IV型钢板桩应用于孟加拉达舍尔甘地污水处理厂双GRP管道铺设时安全防护的工艺性试验,对试验结果进行了必要的分析并对其施工安全进行了判断。针对大管径双GRP管道在高浅表水、软基且附近有高压线塔和高楼等不利外部条件下采用钢板桩防护施工安全进行了观测和必要的数值分析,确定了GRP管道铺设在不利外部条件下最佳的钢板桩防护方式,为在类似地区开展类似的工作提供参考。
The technological experiment for the safety protection during the application of Larsen's type III and V steel sheet piles to the construction of large-size dual GRP(Glass Fiber Reinforced Plastics)pipeline for Dasherkandi Sewage Treatment Plant in Bangladesh is described herein,and the necessary analysis is made on the experimental result,while the relevant judgment on the construction safety is carried out as well.The construction safety of the large-size dual GRP pipeline protected by steel sheet pile under the unfavorable external conditions of high-level groundwater and soft foundation with high voltage power transmission towers and high buildings nearby is observed along with the relevant necessary numerical analysis,and then the optimal mode of the steel sheet pile protection for the laying construction of the GRP pipeline under those unfavorable external conditions is determined,which provides a certain reference for the construction of the similar project in the similar region.
