Excavation construction method for dredger fill fluid sludge roadbed
The invention discloses a dredger fill fluid sludge roadbed excavation construction method which specifically comprises the following steps: before roadbed excavation, pre-proportioned sandy soil is uniformly laid above a fluid sludge stratum to form a sand layer; a cofferdam and an unearthed shortcut are built, and the cofferdam is fixed to the outer side of a preset road red line and can meet the collaborative operation requirement of a transport vehicle and an excavator; excavation construction is conducted, a working cushion layer is laid, and in the excavation construction process, fluid sludge is continuously excavated towards the two sides of the unearthed shortcut and the space between the cofferdams through an operation vehicle on the unearthed shortcut. According to the method, sludge backfilling can be effectively prevented, and the construction efficiency is improved.
本发明公开了一种吹填土流质淤泥路基开挖施工方法，具体包括如下步骤，在路基开挖前采用预先配比好的砂性土在流质淤泥地层上方均匀铺设形成砂层；修筑围埝和出土便道，所述围埝固定在预先设定的道路红线的外侧，并且能够满足运输车和挖掘机的协同作业要求；开挖施工、铺设工作垫层，在所述开挖施工过程中，通过在出土便道上的作业车辆不断向出土便道两侧以及围埝之间掏挖流质淤泥。所述方法能够有效的防止淤泥回填，提高施工效率。
