混凝土铰链排用软体排沉放船沉排施工工法

Construction method of row sinking of soft row sinking boat for concrete hinge row

混凝土铰链排作为一种沉排护底工艺,已在江河整治工程中广泛应用。本文以湖北荆江河控工程为例,详细介绍了利用软体排铺排船进行混凝土铰链排施工的工艺技术。该技术解决了前期改装沉排船带来的投资过高问题。后期通过在排布上加设高强涤纶布筋条来增强排布的抗拉性能,有效解决了沉排施工过程中排布拉裂问题。该施工工艺安全可靠,提升了施工质量,具有较高的借鉴价值。

Concrete hinge row,as a row sinking bottom protection technology,has been widely used in river regulation projects.The control project of Jingjiang River in Hubei Province is adopted as an example in the paper.The construction technology of concrete hinge row by using the soft row paving boat is introduced in detail.The technology solves the problem of high investment caused by the early modification of sinking boat.The tensile performance of the layout is enhanced late through adding high-strength polyester cloth bars to the layout,thereby the problem of layout tension crack in the construction process of sink drainage is effectively solved.The construction technology is safe and reliable,which improves the construction quality and has high reference value.
