Riverbed flow guide structure for hydraulic engineering construction
The invention relates to a riverbed flow guide structure for hydraulic engineering construction. The riverbed flow guide structure comprises an outside water retaining cofferdam, a grass-soil cofferdam attached to the outer side of the outside water retaining cofferdam, an inside water retaining cofferdam arranged at the inner side of the outside water retaining cofferdam by being spaced by a certain distance and a bucket flow face arranged between the inside water retaining cofferdam and the outside water retaining cofferdam. The inside water retaining cofferdam and the outside water retaining cofferdam form a flow guide open channel. The bucket flow face is arranged at a crossed water outlet of the flow guide open channel and an original riverway. The riverbed flow guide structure has the beneficial effects that by arranging the steel plate cofferdams and the grass-soil cofferdam, the flow guide open channel which is high in strength, free of leakage, low in manufacturing cost and capable of being repeatedly used can be formed; and by arranging the bucket flow face, the impact of river water on the flow guide structure can be relieved, a scour pit is quite shallow, and the service life of the flow guide open channel is prolonged.
本发明涉及一种水利工程施工用河床导流结构，包括外侧挡水围堰、与所述外侧挡水围堰外侧贴合的草土围堰、设置在所述外侧挡水围堰内侧并有一定距离的内侧挡水围堰以及设置在所述内侧挡水围堰与所述外侧挡水围堰之间的戽流面，所述内侧挡水围堰与所述外侧挡水围堰组成导流明渠；所述戽流面设置在导流明渠与原先河道的交叉出水口。本发明的有益效果是通过设置钢板围堰和草土围堰，可以组成具有高强度、不渗漏、造价低、可重复利用的导流明渠；通过设置的戽流面，可以减轻河水对导流结构的冲击，冲刷坑比较浅，延长导流明渠的使用寿命。
