Fabricated cofferdam suitable for seawall construction and construction method
The invention provides an assembly type cofferdam suitable for seawall construction and a construction method. The assembly type cofferdam is formed by splicing a plurality of foundation units up and down and left and right; the basic unit is prism concrete with a right triangle-shaped cross section; splicing grooves are formed in the foundation units along three edges of a prism respectively, and the splicing grooves are formed after the foundation units are spliced up and down to be used for arranging expansion water stop strips. A plurality of hole grooves are formed in the foundation units, the hole grooves vertically penetrate through the whole foundation units, and fixing piles penetrate through the hole grooves to limit the foundation units which are vertically spliced. According to the combined cofferdam, the basic units in modular design are adopted, cofferdams of various heights and shapes can be spliced and combined according to actual needs, the application range is wide, assembling and disassembling are convenient, the construction period is short, and the maintenance cost is low; in addition, the foundation unit is high in integrality and strong in anti-scouring capacity, the foundation unit can be reused, the influence of the construction process on the environment is small, and the marine ecological environment can be protected easily.
本发明提供一种适用于海塘施工的装配式围堰及施工方法，所述装配式围堰由多个基础单元上下、左右拼接而成；所述基础单元为横截面为直角三角形的棱柱混凝土；所述基础单元沿着棱柱的三条棱分别设有拼槽，所述拼槽在基础单元上下拼接后形成拼接槽以用于设置膨胀止水条；所述基础单元上设有多个孔槽，所述孔槽上下贯穿整个基础单元且所述孔槽内贯穿固定桩以限位上下拼接的基础单元。本发明采用模块化设计的基础单元，可根据实际需要拼接组合成各种高度与形状的围堰，适用范围广，便于组装与拆除，施工周期短，维护成本低；此外，本发明的整体性高、抗冲刷能力强，基础单元可重复利用，施工过程对环境影响较小，有利于保护海洋生态环境。
