Novel cofferdam and construction method thereof
The invention discloses a novel cofferdam and a construction method thereof. The novel cofferdam comprises steel pipe piles and first steel sheet piles, wherein the steel pipe piles are inserted into a riverbed and extend to a rock stratum, the steel pipe piles are arranged in a surrounding mode to form a cofferdam structure, the first steel sheet piles are inserted into the riverbed and extend to the rock stratum, all the first steel sheet piles surround the outer side of the cofferdam structure and are connected with the corresponding steel pipe piles, and the adjacent first steel sheet piles are meshed with one another through clamping hooks. The construction method of the novel cofferdam comprises the following steps that the plurality of steel pipe piles and first steel sheet piles are inserted into the riverbed, the multiple steel pipe piles are arranged in the surrounding mode to form the cofferdam structure, all the first steel plate piles are arranged on the outer side of the cofferdam structure, a drilling machine stretches into the steel pipe piles to drill a channel on the rock stratum, muddy water in the steel pipe piles is pumped out, and reinforcement cages are put down in the steel pipe piles so that part of the reinforcement cages can be located in the channel of the rock stratum and part of the reinforcement cages can be located in the steel pipe piles, concrete is poured into the steel pipes piles, the concrete and the reinforcement cages are combined to form anchoring piles, and a foundation platform is dug out inside the cofferdam structure. The novel cofferdam and the construction method thereof are used for the field of bridge construction.
本发明公开了一种新型围堰及其施工方法，新型围堰包括钢管桩，插入河床并延伸至岩层，各钢管桩环绕布置形成围堰结构；第一钢板桩，插入河床并延伸至岩层，各第一钢板桩围绕在围堰结构外侧并与相应的钢管桩连接，相邻第一钢板桩之间通过卡勾相互咬合，新型围堰的施工方法，包括以下步骤：将多个钢管桩和第一钢板桩均插入河床，多个钢管桩环绕布置形成围堰结构，各第一钢板桩布置在围堰结构外侧，钻机伸入钢管桩在岩层上钻出通道，抽干钢管桩内的泥水，钢管桩内下放钢筋笼，以使部分钢筋笼位于岩层的通道中，部分钢筋笼位于钢管桩内，钢管桩内灌注混凝土，混凝土与钢筋笼结合形成锚固桩，在围堰结构内部挖出基础承台，本发明用于桥梁建筑领域。
