Cemented pebble geological cofferdam construction method and cofferdam structure
The invention relates to the field of cofferdam construction processes, in particular to a cemented pebble geological cofferdam construction method and a cofferdam structure, the construction method comprises the following steps: step 1, initially cleaning a foundation; 2, constructing a steel casing and a steel pipe pile structure; 3, a temporary supporting structure is erected; step 4, secondary base cleaning; 5, bottom sealing concrete is poured; 6, ring beams are erected; seventhly, a bearing platform is constructed; 8, arch support construction is conducted; 9, refilling water in the cofferdam; according to the construction method of the cemented pebble geological cofferdam, secondary foundation cleaning operation of the cofferdam can be achieved through arrangement of a temporary supporting structure, in addition, according to the construction method of the cofferdam, water liquid is adopted for supporting the interior of the cofferdam, so that the cofferdam has the self-balancing capacity, and the cofferdam is protected from being damaged. The safety of deepwater cemented pebble stratum cofferdam construction is ensured, meanwhile, the cofferdam construction efficiency is improved, and the construction risk and difficulty are reduced.
本发明涉及围堰施工工艺领域，具体来说是一种胶结卵石地质围堰施工方法以及围堰结构，所述施工方法包括如下步骤：步骤1：初始清基；步骤2：钢护筒和钢管桩结构施工；步骤3：临时支撑结构架设；步骤4：二次清基；步骤5：浇筑封底混凝土：步骤6：圈梁架设；步骤7：承台施工；步骤8：拱座施工；步骤9：围堰内回灌水；本发明公开了一种胶结卵石地质围堰施工方法，本发明通过临时支撑结构的设置，可以实现围堰的二次清基操作，另外，本发明公开的围堰施工方法，采用了水液来对围堰内部进行支撑，使得围堰具有自平衡能力，确保了在深水胶结卵石地层围堰施工的安全，同时提高了围堰施工效率，降低了施工风险和难度。
