Construction method of wood-bamboo clay cofferdam
The invention discloses a construction method of a wood-bamboo clay cofferdam. The construction method comprises the following steps of: compiling a survey report; establishing a wind wave full-coupling power system calculation model to realize simulation of a wind, wave and ocean current full-coupling effect in a complex marine environment; performing cofferdam division in a mud flat area to determine the cofferdam building position; determining the structural form of cofferdam building to finish equipment material station entering; compiling a cofferdam construction scheme; carrying out dredging and finishing work of a bottom foundation at the cofferdam building position to enable the bottom foundation of the cofferdam to reach enough bearing capacity; finishing side wall building; starting to lay a first layer of moso bamboo pieces to block side wall gaps; performing a base layer paving procedure on the bottom and the side walls of the cofferdam; taking clay nearby the sites on the two sides of the cofferdam, and filling the clay into a cofferdam body to form an anti-seepage clay wall to finish a first layer of cofferdam; and finishing a second layer of cofferdam according to the first layer of cofferdam. According to the construction method, the cofferdam construction efficiency can be improved, the construction period can be shortened, the water-resistant and anti-seepage effects can be improved, the settlement can be reduced, and the excavation amount of a covering layer and the filling amount of the cofferdam body in construction can be reduced.
本发明一种木竹黏土围堰的施工方法，包括：编制勘察报告；建立风流浪全耦合动力系统计算模型，实现复杂海洋环境下风、波浪、洋流全耦合作用的模拟和仿真；在滩涂区域进行围堰划分，确定修筑围堰的位置；确定修筑围堰的结构形式，完成设备材料进站；编制围堰施工方案；开展修筑围堰处底部基础的清淤、修整的工作，使围堰底部基础达到足够的承载力；完成的边墙修筑；开始铺设第一层毛竹片封堵边墙空隙；对围堰底部、边墙进行铺垫基层工序；在围堰两侧场地就近取黏土，填筑到堰体内形成防渗黏土墙完成第一层围堰；依此完成第二层围堰。本发明能够提高围堰施工效率、缩短工期，改善抗水防渗作用减少沉降，降低施工中覆盖层开挖量和堰体填筑量。
