The front slope of the dam is greatly impacted by water, and the direct impact of the water flow on the front slope of the dam is likely to cause damage to the dam
At present, gravel is often used to fill the front slope of the embankment to buffer the impact from the water flow, but the shape of the gravel is different, which will cause some water flow to increase rapidly and cause more serious impact on some areas of the embankment

Abstract
An impact-resistant dam comprises a plurality of dam units. Each dam unit is composed of a front slope and a rear slope, wherein a plurality of steel bars are evenly arranged on the front slope, one end of each steel bar is poured in the corresponding dam unit, an arc base is arranged at the other end of each steel bar, the steel bars are perpendicular to the front slope, a frustum is poured on the periphery of each steel bar, the lower bottom of each frustum is attached to the front slope of the corresponding dam unit, the upper bottom of the frustum is attached to the bottom of the arc base, and a reinforcing layer is poured to the part, between every two frustums, of the front slope. According to the impact-resistant dam, when water flow impacts the dam, the water flow still directly impacts the front sections of the frustums and can be distributed along the peripheries of the frustums, the impact force is diverted at the same time, the diverted water flow impacts the front slope obliquely, and thus the impact resistance of the dam is effectively improved. The frustums are fixed through the steel bars and are high in stability, the arc bases are installed at the upper bottoms of the frustums, arc faces can relieve the direct-impacting water flow, and the impact resistance is improved; the arc bases protect the upper bottoms of the frustums, and the service life of the frustums is prolonged.
Description
technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to an anti-shock dam. Background technique [0002] Dams are important equipment for flood control and flood fighting. The front slope of the dam is greatly impacted by water, and the impact of the water flow directly on the front slope of the dam is likely to cause damage to the dam. At present, most of the gravel is filled on the front slope of the embankment to buffer the impact from the water flow, but the shape of the gravel is different, which will cause some water flow to increase rapidly and cause more serious impact on some areas of the embankment. Contents of the invention [0003] The invention provides an anti-shock embankment to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] An anti-shock dam, including several dam units, each dam unit is composed of a front slope and a ...
