垃圾填埋场渗滤液积存池坝体加固水下岩土工程勘察设计

针对复杂环境及地质条件下的垃圾填埋场渗滤液积存池坝体水下加固勘察设计工程,选择双船并联搭建水上漂浮钻场,全套管护壁钻进,查明垃圾填埋场渗滤液积存池坝体地基土的组成及分布特征,并根据岩土工程评价参数,结合现场地质条件及施工条件,设计钢板桩+钢筋混凝土护坡桩的坝体支护方案,以确保坝体加固施工期间的隔水功能和整体稳定性。

Aiming at the underwater reinforcement survey and design project of landfill leachate accumulation pool dam body under complex environment and geological conditions,two ships are selected to build floating drilling site in parallel,and a full set of pipe wall protection is drilled.The composition and distribution characteristics of the foundation soil of the landfill leachate accumulation pool dam body are found out,and according to the geotechnical engineering evaluation parameters,according to the site geological conditions and construction conditions.The dam body support scheme of steel sheet pile and reinforced concrete slope protection pile is designed to ensure the water isolation function and overall stability of the dam during the reinforcement construction.
