Cofferdam construction device and method capable of realizing three-dimensional drainage and vacuum preloading treatment for bagged sludge
The invention discloses a cofferdam construction device and method capable of realizing three-dimensional drainage and vacuum preloading treatment for bagged sludge. The cofferdam construction devicecapable of realizing three-dimensional drainage and vacuum preloading treatment for the bagged sludge comprises an anti-seepage geotextile bag and a drainage assembly, wherein a sludge filler is filled into the anti-seepage geotextile bag; the drainage assembly is arranged in the anti-seepage geotextile bag; and water in the sludge filler is extracted through a vacuumizing device connected with the drainage assembly, so that the sludge in the anti-seepage geotextile bag is rapidly solidified to achieve the requirements of strength and stability. The process has the advantages of being simple in construction procedure, high in solidification and drainage efficiency, high in cofferdam strength and stability, low in project cost, and the like, and is wide in application field, and especiallyappliable to various overwater cofferdam projects and underground cofferdam projects such as land, sea and lakes; and the sludge is used for replacing a sand source, so that the problem of sludge discarding is solved, and the problem of sand source scarcity is also solved.
本发明公开了立体排水真空预压处理袋装淤泥围堰施工装置、方法，包括防渗土工模袋、排水组件，所述防渗土工模袋内填充有淤泥填充剂，所述排水组件设于所述防渗土工模袋内，通过与所述排水组件连接的抽真空装置，以将淤泥填充剂中的水分抽出，使防渗土工模袋内淤泥快速固结达到强度及稳定性要求。本发明的工艺具有施工工序简单、固结排水效率高、围堰强度及稳定性高、工程造价低等优点，且应用领域广，尤其适用于陆地、海湖等各类水上、水下围堰工程，将淤泥代替砂源，即解决了淤泥弃置问题，也解决了砂源紧张问题。
