Sealing and water stopping structure for splicing caisson steel cofferdam
The invention discloses a sealing and water stopping structure for splicing caisson steel cofferdams, and relates to the technical field of water transportation engineering construction.The sealing and water stopping structure comprises steel caissons, steel sheet piles and a plugging mechanism, the steel caissons, the steel sheet piles and the plugging mechanism are all inserted into a riverbed, locking fasteners are welded to the two sides of the steel caissons, the steel sheet piles are arranged between any two steel caissons, and the locking fasteners are connected with the locking fasteners. The two sides of the steel sheet pile are fixedly connected with the steel caissons by inserting two locking fasteners, a plugging mechanism is further arranged between the two steel caissons, and a sealing water stop structure is arranged between the plugging mechanism and the steel sheet pile; the sealing and water stopping structure comprises an inserting mechanism, a pressurizing mechanism and soil, the pressurizing mechanism is installed on the inserting mechanism, the inserting mechanism guides the pressurizing mechanism into the position between the plugging mechanism and the steel sheet pile, the pressurizing mechanism is covered with the soil, the soil is extruded through expansion of the pressurizing mechanism, and the gap between the plugging mechanism and the steel sheet pile is tightly plugged by the soil; and the sealing degree between the plugging mechanism and the steel sheet pile is improved.
本发明公开了一种沉箱钢围堰拼接用密封止水结构，涉及水运工程施工技术领域，包括钢沉箱、钢板桩和封堵机构，钢沉箱、钢板桩和封堵机构均插设在河床上，钢沉箱两侧焊接有锁扣件，钢板桩设置在任意两个钢沉箱之间，且钢板桩两侧通过插入两个锁扣件与钢沉箱固定连接，两个钢沉箱之间还设有封堵机构，封堵机构与钢板桩之间设有密封止水结构；密封止水结构包括插接机构、加压机构和泥土，加压机构安装在插接机构上，插接机构将加压机构导入封堵机构与钢板桩之间，并用泥土覆盖加压机构，通过加压机构膨胀挤压泥土，使得泥土紧密的封堵封堵机构与钢板桩之间的间隙，提高封堵机构与钢板桩之间的密封程度。
