Steel-concrete vacancy filling cofferdam construction method based on lake and reservoir area full rock stratum abrupt slope
The invention relates to a reinforced concrete vacancy filling cofferdam construction method based on a lake and reservoir area full rock stratum abrupt slope. The construction method comprises the following steps: construction; steel pipe pile vibration sinking, pile top leveling, pile top steel plate laying as a temporary construction platform, rotary drilling machine driving into the temporary construction platform to conduct hole guiding on cofferdam steel pipe pile, cofferdam steel pipe pile vibration sinking, cofferdam steel pipe pile tying by using profile steel waist beam outside cofferdam steel pipe pile, and cofferdam steel sand is poured into the pipe piles; waterproof geotechnical cloth is laid from the top of the cofferdam to a riverbed; redundant steel pipe piles are pulled out; cofferdam concrete is poured; the construction method has the beneficial effects that the temporary construction platform can be quickly built by using the construction method, and the concrete is used as the cofferdam main body, so that the construction progress is accelerated, the water retaining performance of the foundation pit is improved, the construction safety of the foundation pit is improved, and the construction cost is saved.
本发明涉及一种基于湖库区全岩层陡坡的钢混补缺围堰施工方法，该施工方法包括如下步骤：旋挖机在岸上基岩对河床进行引孔→振动下沉钢管桩→桩顶找平→铺设桩顶钢板作为临时施工平台→旋挖机驶入临时施工平台对围堰钢管桩引孔→振动下沉围堰钢管桩→围堰钢管桩外使用型钢腰梁对围堰钢管桩进行拉结→围堰钢管桩内部灌砂→从围堰顶至河床铺设防水土工布→拔除多余钢管桩→浇筑围堰混凝土→基坑开挖施工；本发明的有益效果为：使用本施工方法可迅速搭建临时施工平台，使用混凝土作为围堰主体，从而加快了施工进度，提高了基坑挡水性能，增加了基坑施工的安全性，节约了施工成本。
