Construction method for connection of new and old sewage wells without cutting off water
The invention discloses a construction method for connection of new and old sewage wells without cutting off water. The construction method comprises the steps of preparation before construction, construction of a pre-plugging device, construction of a connection well, construction of a connection structure, final connection and the like. The arc-shaped flashboard is used for pre-blocking the old sewage well, and construction is carried out under the condition that operation of an existing sewage system is not affected. A steel caisson is installed beside an old bilge well in a sinking mode to serve as a connection well, operation is conducted in the connection well, concrete is poured between a jacking pipe and a connection pipe for seepage prevention, and finally communication of the new bilge well and the old bilge well is achieved.
本发明公开了一种用于新旧污水井不停水接驳的施工方法，包括施工前准备、预封堵装置施工、接驳井施工、接驳结构施工、最终接驳等步骤。本发明利用弧形闸板对旧污水井进行预封堵，在不影响现有污水系统运行的情况下进行施工。在旧污水井旁下沉安装钢沉箱作为接驳井，接驳井内作业，顶管和接驳管之间灌砼防渗，最终实现新旧污水井连通。
