Riverway drainage basin flood prevention dam construction method
The invention relates to the technical field of dam construction, in particular to a riverway drainage basin flood prevention dam construction method. The method comprises the following steps that before concrete construction, beach protection project is conducted on the slope surface in front of a flood prevention wall, wherein the beach protection project comprises the following steps that S1, silt is removed, and the slope surface in front of the flood prevention wall is flattened; S2, paying-off positioning is conducted, the border of the slope surface is dug, and a groove is processed; S3, polypropylene filament yarn woven cloth is thrown in front of the flood prevention wall at first, then, rubble is thrown for filling, the gradient of the slope reaches 1:2.5; and S4, net bag gabionsare adopted at the toe of the slope to protect the toe, leveling of the upper portion of the thrown rubble is achieved with bagged broken stone, and the surface is protected through film-bagged concrete. Before concrete construction, the slope surface is protected through the beach protection project, the soil and water loss situation is avoided, the integrity of the slope surface is improved, and the water ecology of the slope surface is stabilized and protected from being damaged.
本发明涉及堤坝施工的技术领域，尤其是涉及一种河道流域防汛堤坝的施工方法，方法如下：在施工混凝土前，对防汛墙前的坡面施工保滩工程；保滩工程的步骤如下：S1，清淤并平整防汛墙前的坡面；S2，放线定位，开挖坡面的边界，处理沟槽；S3，在防汛墙前先抛丙纶长丝机织布，再抛填块石，使坡度达到1：2.5；S4；坡脚处采用网兜石笼护脚，在抛石上方用袋装碎石找平，再用膜袋混凝土护面。在施工混凝土前采用保滩工程对坡面进行保护，避免产生水土流失的情况，提高坡面的完整性，稳定坡面的水生态不被破坏。
