Underwater concrete scour pit repairing construction method and device
The invention belongs to the technical field of underwater operation construction, and provides an underwater concrete scouring pit repairing construction method and device.The construction method comprises the following steps that S1, a water retaining piece is arranged at the upstream corresponding position of a scouring pit to be repaired; s2, filling the scouring pit to be repaired with an underlying medium; s3, a formwork is arranged on the scouring pit to be repaired, and a pouring hole and a plurality of drainage holes are reserved in the formwork; s4, concrete is poured into the to-be-repaired scouring pit through the pouring holes in the formwork till the to-be-repaired scouring pit is filled with the concrete; and S5, after the concrete in the to-be-repaired scouring pit is cured to reach the standard, the formwork and the water retaining piece are detached, and repairing construction is completed. According to the construction method, a cofferdam does not need to be built, construction can be completed by providing a still water operation environment for construction through the water retaining piece, the construction procedure is reduced, the manufacturing cost is saved, the construction period is short, and underwater repair of the scour pit can be rapidly completed.
本发明属于水底作业施工技术领域，提供一种水底混凝土冲刷坑修复施工方法及装置，其中的施工方法包括以下步骤：S1、在待修复的冲刷坑的上流对应处布置挡水件；S2、向待修复的冲刷坑填充底下介质；S3、在待修复的冲刷坑上布置模板，在所述模板上预留浇筑孔以及多个泄水孔；S4、通过所述模板上的浇筑孔，向待修复的冲刷坑内浇筑混凝土，直至浇筑填满待修复的冲刷坑；S5、当待修复的冲刷坑内的混凝土养护达标后，拆卸所述模板和所述挡水件，完成修复施工。本发明的施工方法，无需修建围堰，通过挡水件为施工提供静水作业环境即可完成施工，该技术缩减施工程序，节约造价成本，且施工周期短，有利于快速完成冲刷坑的水下修复。
