摘要
超轻型井点专利技术应用几年来解决了很多实际难题,在北医三院基坑工程中弥补了管井降水的不足,尤其局部流砂层中,采用了小角度斜向设置并改用布袋有效地解决了流砂层降水问题,确保了基坑复合土钉墙的施工。实践证明,超轻型井点专利技术配合管井降水在深大基坑地下水控制尤其针对局部流砂层,是一项很实用的技术。
Many practieal difficulties were solved by the patent technique for ultra-light well site dewatering in these years, whieh was applied in a foundation pit engineering to remedy insufficient dewatering of tube well. In local quicksand layer, well tube was obliquely and quasi-horizontally set to realize dewatering and ensure the construction of excavation with compound soil nail support.
