我处在齐齐哈尔太平路23、24铁路住宅楼工程中,首次应用“一次铺入、分层振实”法进行基础砂垫层的施工,获得成功。 23、24住宅楼为七层砖混结构,基础下卧层为轻亚粘土,流塑,设计换填1M厚砂垫层。 本工程的土方作业于上年12月上旬完成,因冬季难以保证砂垫层质量,为防止基底受冻,土方完成后立即虚铺1.2M厚混砂,表面复盖雪0.6M厚。
In the project of 23,24 railway residential buildings in Taiping Road, Qiqihar, I was the first to apply the “one-time laying and stratified charging” method to construct the foundation sand bedding and achieve success. 23,24 residential building is a seven-story brick-concrete structure, the foundation of the sub-layer of light-loam clay, plastic flow, designed to replace the 1M thick sand cushion. The earthwork of this project was completed in early December last year. Because it is difficult to ensure the quality of sand cushion in winter, to prevent the base from freezing, the soil will be paved with 1.2M thick sand immediately after completion and the surface covered with 0.6M thick snow.
