Combined type movable cofferdam for embankment danger elimination and reinforcement

Abstract

The invention relates to cofferdams of embankment projects for rivers and lakes, in particular to a combined type movable cofferdam for embankment danger elimination and reinforcement. The cofferdam comprises two uprights, grooves are formed in opposite sides of the two uprights, the two ends of a mutual buckling slab are installed in the grooves I of the two uprights respectively, inclined rails are installed at the lower ends of the two uprights respectively, the other ends of the two inclined rails are connected through a fixed shaft, the included angle between the uprights and the inclined rails is an acute angle, grooves II are formed in the upper sides of the inclined rails, the lower ends of mutual buckling side plates are installed in the grooves II, reinforcement plates I are arranged on the two sides of the upper end and the two sides of the lower end of the mutual buckling slab, and reinforcement plates II are arranged on the two sides of the upper end of each mutual buckling side plate. Compared with the prior art, the cofferdam has the advantages that when a flood danger happens during the flood season, water stopping treatment can be carried out in time, further deterioration of the danger can be avoided, the cofferdam is of a combined structure and is convenient to disassemble and capable of being repeatedly used, and time and labor are saved.

Description

technical field [0001] The invention relates to a cofferdam for embankment engineering of rivers, rivers and lakes, in particular to a combined mobile cofferdam for danger removal and reinforcement of dikes. Background technique [0002] Due to serious sedimentation in the Yellow River Basin, the river beach is generally 3-5m higher than the embankment, and some are more than 10m, forming a "suspended river above the ground". In addition, the embankment is gradually heightened and thickened on the basis of the folk embankment, and the quality is uneven. There are many hidden dangers and the flood control situation is very severe. In order to eliminate hidden dangers and enhance the flood resistance capacity of the project, standardized embankment construction was carried out on the Yellow River. While the embankment was reinforced, silt was released on both sides to reinforce the embankment. At present, the hidden dangers of embankment engineering in my country mainly inclu...

Problems solved by technology

[0018] The technical problem to be solved by the present invention is that in the flood season of the river, on the one hand, it is difficult to construct under the interference of floods, and on the other hand, there is a lack of mature equipment and technical obstacles, and corresponding emergency operations cannot be carried out quickly and safely in the water. In order to solve the above problems , providing a combined mobile cofferdam for embankment danger removal and reinforcement
