摘　　要：拼装式钢箱围堰是为解决施工中提供无水环境而设计的可现场拆装并能重复使用的阻水钢结构。其结构特点是下部为无底框式结构，四周侧钢插板经过适度补强，通过两道钢板墙插入封底阻水；上部为浮箱式结构，可充水下潜，抽水后浮升。箱体可现场进行纵向、横向拼装，可陆路与水路运输。Assembly steel box cofferdam is a water-blocking steel structure which is designed to provide anhydrous state during the construction. It can be disassembled and assembled in site and can be reused in many times. Its structure has the features which its down-part is the structure without bottom frame, embedded steel board around its side has been properly reinforced. And it can be inserted the sealing bottom to block water through two steel plate wall. Its up-part is floating structure,it can submerge by filling water,and buoyancy lift after pumping water. The boxes can be longitudinally or transversely assembled in the scene. They can be transported by roadway or waterway.
