[0002] Cofferdam refers to the temporary enclosure structure built in the construction of water conservancy projects for the construction of permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate the foundation pit, and build the building. Generally, it is mainly used in hydraulic construction, and the cofferdam is generally removed after use. The height of the cofferdam is higher than the highest water level that may occur during the construction period.

[0007] The top part of the cast-in-place pile extends into the inside, the bottom part of the support column extends into the reinforced concrete box culvert bottom plate, and the top part of the support column extends into the reinforced concrete box culvert top plate;

[0008] The upper part of the reinforced concrete box culvert top plate is provided with a green belt near the water side, and the remaining half area is paved with a rubber walkway;

[0009] The upper edge of the water storage tank is provided with a protective fence;

[0010] The inner end of the reinforced concrete box culvert top plate is fixed with a protective net extending into the water storage tank by a length;

[0011] The bottom plate of the water storage tank is inclined from one side of the reinforced concrete box culvert bottom plate to the other side.

[0012] The utility model discloses a beneficial effect: practical, novel structure, the cofferdam foundation of weir is increased with the function of landscape footpath, and can play the flood control buffering effect, especially suitable for the cofferdam use under the condition of not needing to remove. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is cross section structure schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] A cofferdam engineering revetment structure, including the vertical fixed in weir top's bored pile 1, the top of bored pile 1 is horizontally poured with reinforced concrete box culvert bottom plate 2, and the upper portion of reinforced concrete box culvert bottom plate 2 is vertically poured with several evenly distributed support columns 3, and the top of support column 3 is horizontally poured with reinforced concrete box culvert top plate 4, and the backwater side of reinforced concrete box culvert bottom plate 2 and reinforced concrete box culvert top plate 4 is equipped with water storage tank 5, and the water storage tank 5 is communicated with culvert 6 on the water side between reinforced concrete box culvert bottom plate 2 and reinforced concrete box culvert top plate 4.

[0015] As Figure 1 The utility model discloses a beneficial effect: practical, novel structure, the cofferdam foundation of weir is increased with the function of landscape footpath, and can play the flood control buffering effect, especially suitable for the cofferdam use under the condition of not needing to remove.
