Problems solved by technology
[0004] The maximum displacement of the existing built dams is certain, so the flood discharge capacity is limited. When a flood occurs, when the flood volume is too large, huge water pressure will be generated on the dams. When the flood discharge speed of the dams is low When the flood increases, the pressure on the embankment will increase. Under continuous pressure, the embankment will be easily damaged, which will cause great safety hazards to the downstream crops and even the residents themselves.

Embodiment 1
[0040] see figure 1 In the figure, a represents water, and b represents soil at the bottom of the water. A self-expanding anti-blocking and flood discharge dam for water conservancy projects includes a dam body 1. The bottom of the dam body 1 is embedded in the soil at the bottom of the water. evenly spaced outfalls 2.
[0041] see Figure 2-3 , the inner wall of the discharge outlet 2 is provided with a wall-adhering sheath layer 3, and both sides of the wall-attaching sheath layer 3 are provided with a hardened layer 4 inside. The disintegration layers are respectively located directly below a plurality of water outlets 2. The pre-disintegration layer includes an upper bearing crack layer 51 and a lower disintegration layer 52. The upper bearing crack layer 51 is located above the lower disintegration layer 52, and the upper bearing crack layer 51 and the lower disintegration layer The disintegrating layer 52 is fixedly connected, the interior of the embankment body 1 is f...

The invention discloses a self-expanding anti-blocking and flood-discharging dam for water conservancy projects, which belongs to the field of dams. A self-expanding anti-blocking and flood-discharging dam for water conservancy projects includes a dam body, and a plurality of uniformly distributed dams are excavated in the middle of the dam body. The water outlet, the inner wall of the water outlet is provided with a wall-attached sheath layer, which can be bonded to the wall-attached sheath layer and the force-hardened layer under the action of water pressure during flood discharge. The deformation and hardening of the inner wall of the discharge port can have a certain buffering effect on the water pressure, effectively improving the strength of the dam and prolonging the service life. The invisible expansion tank is vacated and connected with the discharge outlet, so as to realize the expansion of the discharge outlet, effectively increase the flood discharge volume, increase the flood discharge speed, and relieve the pressure caused by excessive accumulated flood water on the embankment, thereby effectively preventing the embankment from being washed away. situation and reduce potential safety hazards.
Description
technical field [0001] The invention relates to the field of dams, in particular to a self-expanding anti-blocking and flood-discharging dam for water conservancy projects. Background technique [0002] The general term of embankments and dams also refers to buildings and structures that are waterproof and water-retaining: for example, it is necessary to step up the construction of dikes and dams to prevent flooding. There are two main types of modern dams: earth-rock dams and concrete dams. In recent years, large-scale dams have adopted high-tech reinforced concrete construction. [0003] Concrete dams are mostly made of concrete, usually in deep and narrow valleys, because only concrete can withstand the high water pressure at the bottom of the dam. Concrete dams can be subdivided into concrete gravity dams, concrete arch dams, concrete buttress dams, etc. The main feature of a concrete dam is to use its own weight to support the pressure of the water body. The main fu...
