Flood control and discharge method for temporary reinforcement of dam

Abstract

The invention discloses a flood prevention and discharge method for temporary reinforcement of a dam, and belongs to the field of dam reinforcement methods.According to the flood prevention and discharge method for temporary reinforcement of the dam, an existing flood prevention sandbag can be selected as a flood prevention sandbag, an adhesion strengthening pad is fixedly connected to the flood prevention sandbag, and then the adhesion strengthening pad is carried on the dam; when the flood overflows the dam and makes contact with the temporary dam, the flood can be scoured, permeates into the flood control sandbag and then enters the filling cavity through the fixing barbs, the hydraulic particle filler is dissolved, seeps out of the adhesion strengthening pad and enters the partition part located on the outer side of the adhesion strengthening pad, and the temporary dam is formed. The adjacent flood prevention sandbags are fixed together, the flood prevention capacity of the temporary dam composed of the flood prevention sandbags is improved, the structural strength of flood prevention sandbag stacking can be greatly improved, the capacity of the flood prevention sandbags for resisting continuous flood scouring is improved, and structural collapse of the stacked flood prevention sandbags is not prone to being caused.

Description

technical field [0001] The invention relates to the field of dam reinforcement methods, and more particularly, to a flood control and flood discharge method for temporary reinforcement of dams. Background technique [0002] The dam is the general name of the embankment and the dam, and also refers to the buildings and structures that are waterproof and water-retaining. In recent years, large embankments have been constructed with high-tech reinforced concrete, and earth-rock dams are wide dams built with earth or stone. The bottom is wider than the top because the water pressure on the bottom is much greater than that on the top. Most of the earth-rock dams were built across the Great River, using common and cheap materials. Because the material is relatively loose, it can withstand the shaking of the foundation. But the water slowly seeps into the dike, reducing its strength. Therefore, engineers will add a layer of waterproof clay to the surface of the embankment, or d...

Problems solved by technology

[0004] The existing method of using sandbags for flood control is only to pile up on the embankment to increase the height of the embankment, thereby increasing its resistance to floods. However, the simple accumulation of sandbags for flood control can only cope with the rise of the flood water level. Continuous scouring can easily cause the structure of accumulated flood control sandbags to collapse and lose their ability to resist floods
