Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-3, a kind of prefabricated cofferdam structure of hydraulic engineering, including it is triangular prism shaped steel frame, anti-
Ooze film, film bag, concrete block, iron stay, earth bag spats.Triangular prism shaped steel frame 1 includes forming seepproof screen 7, steel by sheet pile 11
The chassis that the cofferdam bottom and steel bar 10 that silk screen cover 2 forms are welded into.Seepproof screen outer 7 is made up of sheet pile 11, and outside nail has described anti-
Film is oozed, film bag 4 is stacked at cofferdam bottom, and film bag 4 stacks concrete block 12, triangular prism built with antiseepage ox-hide sand 9, the top of film bag 4
