Cofferdam reinforcement construction method under overwater island building environment
The invention relates to the technical field of building construction, in particular to a cofferdam reinforcing construction method under an overwater island building environment, which comprises the following steps: carrying out block stone silt squeezing construction; construction of backfill soil; constructing a cement mixing pile; laying a first piece of geotechnical non-woven fabric; constructing a gravel slope protection layer; reversely wrapping with a second geotextile; constructing a block stone slope protection layer; the cofferdam reinforcing construction method in the overwater island building environment has the beneficial effects that sludge at protection feet on the outer side of the cofferdam is cleaned, a block stone silt squeezing technology is adopted, double rows of cement mixing piles with the diameter being 600 mm and the distance being 450 mm are additionally arranged on the cofferdam, and gravel slope protection layers are wrapped with inner geotechnical non-woven fabric and outer geotechnical non-woven fabric; the broken stones are prevented from running off under the flushing of river water and the river water is blocked; the defects of a traditional cofferdam reinforcing technology are overcome, the water resisting and scouring preventing effects are improved, the cofferdam structure is strengthened, meanwhile, piping and water seepage can be effectively prevented, the construction difficulty can be lowered, and the construction period can be shortened.
本发明涉及建筑施工技术领域，具体为一种水上筑岛环境下围堰加固施工方法，包括以下步骤：块石挤淤施工；推填土施工；水泥搅拌桩施工；第一道土工无纺布铺设；碎石护坡层施工；第二道土工布反包；块石护坡层施工；有益效果为：本发明提出的水上筑岛环境下围堰加固施工方法采用围堰外侧护脚处淤泥清理采用块石挤淤技术、围堰上加设直径600mm间距450mm双排水泥搅拌桩、使用内、外两道土工无纺布包裹碎石护坡层，防止碎石在河水冲刷下流失和起到阻隔河水作用；解决传统围堰加固技术的不足，改善隔水及放冲刷效果，加强围堰结构，同时也可以有效的阻止管涌、渗水问题，并能够降低施工难度，节约工期。
