Safe riverway cofferdam and construction method thereof
The invention relates to the technical field of water conservancy construction, in particular to a safe riverway cofferdam, the riverway cofferdam adopts a steel pipe pile cofferdam, the top elevation of the cofferdam is 4.5 m, the top width of the cofferdam is 4 m, two rows of seamless steel pipe piles with the outer diameter of 27.3 cm, the wall thickness of 8 mm and the length of 9 m are adopted for supporting a cofferdam main body, the center-to-center distance of the steel pipe piles is 0.5 m, the two sides are longitudinally connected through 2 phi 50 longitudinal purlin steel pipes, transverse connection adopts phi 16 steel bars for connection, and the inner wall adopts bamboo curtain pieces which are arranged in a staggered mode and geotextile. The filling soil in the weir is filled with clay with better compactness. According to the safe river channel cofferdam, the overall structure is more stable, construction is easy, good safety can be provided, and a safe environment is provided for water conservancy construction; the invention discloses a construction method of a safe riverway cofferdam, which optimizes construction steps, ensures good connection between a main body and double arms of the cofferdam, ensures the stability and safety of the cofferdam, and clarifies maintenance and flood control work after cofferdam construction is completed.
本发明涉及水利施工技术领域，具体为一种安全型河道围堰，所述河道围堰采用钢管桩围堰，围堰顶高程4.5m，顶宽4m，且围堰主体支撑采用两排外径27.3cm、壁厚8mm、长9m的无缝钢管桩，钢管桩中心间距为0.5m，两侧纵向连接采用2φ50纵向围檩钢管连接，横向连接采用φ16钢筋连接，内壁采用竹帘片交错排列和土工布。堰内填土采用密实性较好粘土的填心。本发明的安全型河道围堰，整体结构更为稳固，并且易于施工，能够提供很好的安全性，为水利施工提供安全环境；本发明公开了一种安全型河道围堰的施工方法，进行了施工步骤的优化，确保围堰的主体和双臂之间具有良好的联系，保证了围堰的稳固性和安全性，并且明确了围堰施工完成之后的养护和防洪工作。
