地下连续墙施工时,成槽并一清后,地下连续墙钢筋笼就位,然后安装导管,以导管帽为集成安装连接导管、风管、回浆管,连接泥浆分离器、泥浆箱连接。压缩空气从风管底部通过气液混合器排出后与泥浆混合,浆气混合物因其比重小而上升,并在气压动量的联合作用下,不断补浆,槽内泥浆、空气、沉渣的三相流沿导管向上运行至回浆管,排入泥浆分离器,过滤出泥浆中的沉渣,泥浆又重新进入槽段内,反复循环。
When the underground diaphragm wall is constructed, a steel cage shall be placed in the underground continuous wall after it is trenched and cleared. Then, a conduit is installed, and the conduit cap is used as an integrated installation to connect a connecting duct, an air duct, a return pipe, a connecting mud separator and a mud box. Compressed air from the bottom of the duct through the gas-liquid mixer after mixing with the mud, slurry mixture due to its small proportion and rise, and in the joint action of the pressure momentum, continuous replenishment, tank mud, air, sediment three-phase Flow along the catheter up to the return pipe, into the mud separator, filter out the sediment in the mud, mud and re-enter the trough section, repeated cycles.
