摘要
临江河深基坑支护与降水等关键环节能显著影响基坑外围的建筑物尤其是江河堤防的稳固与否.以富春江三山堤加固工程为例,根据水文、地质地形条件,通过计算,采用拉森Ⅳ型钢板桩支护,同时采用在钢板桩外侧设井点降水,基坑内设深井降水进行联合降水,并沿围堰脚设置排水沟,并做好围堰的防渗处理工作.该工程技术在应用中效果良好.
The supporting and dewatering of riverside deep foundations are obviously significant to the steadiness of buildings outside the foundation ditch as well as the dike.Based on the dike reinforcement case of Sanjiangdi in Fuchun River,according to the hydrological and geological conditions,the engineering technology is introduced by supporting with IVshaped steel sheet pile and well-pointed dewatering outside the pile,combining with deep-well dewatering in foundation ditch and draining in cofferdam with perfect anti-seepage treatment,which is proved to be considerably effective.
