1工程概况泰州2×300兆乏调相机工程紧邻泰州±800kV换流站站区西南侧。该工程处于江苏兴化里下河地区,厂址原为蟹塘、沟渠、水田,在场平时进行了清淤、换填400mm厚级配碎石滤水层,5%~10%灰土(体积比)回填。其中调相机主厂房等区域的基础先进行大开挖施工,然后再进行回填,为了减少厂址地基的下沉,故采用深层水泥土搅拌桩对调相机工程进行复合地基处理。
1 Project Overview Taizhou 2 × 300 trillion missing camera project close to Taizhou ± 800kV converter station southwest side of the station area. The project is located in Lixiahe, Xinghua, Jiangsu Province. The site was originally crab pond, ditch canal and paddy field. Dredging was usually carried out at the site. 400mm thick grade graded aquifer was replaced with 5% -10% lime soil (volume ratio) Backfill. In which the main camera and other regions of the base area of the first large excavation construction, and then backfill, in order to reduce the site of the foundation sinking, so the use of deep cement mixing pile on the camera project complex foundation treatment.
