Description of the reference numerals: 1. a dam body; 2. polysulfide sealant; 3. a traffic bridge; 4. the handrail can be disassembled; 5. an overflow conduit; 6. an overflow trough; 7. an overflow weir; 8. a steel casing.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.
Example one
As shown in fig. 1, the multifunctional submerged dam structure for hydraulic engineering mainly comprises a box-type dam body 1, a traffic bridge 3 and a step-type overflow weir 7.
For connecting left and right bank, 1 top of box dam body sets up bituminous paving traffic bridge 3, is the roadway in the middle of traffic bridge 3, and both sides are the pedestrian way, and 1 top both sides of box dam body set up can dismantle railing 4, and 1 upper portion of box dam body can dismantle railing 4 when crossing water and demolish.
An overflow pipeline 5 in the box-shaped dam body 1 is connected with the upper and lower streams, and the inlet elevation of the overflow pipeline 5 is higher than the outlet elevation. A small amount of incoming water at the upstream can be discharged from the water outlet pipe 5 through the overflow pipe; in order to form the ecological landscape effect, a stepped overflow weir 7 is arranged at the downstream of the dam body 1; in order to form a continuous water surface on the surface of the stepped overflow weir 7, an overflow groove 6 is arranged at the tail end of the overflow pipeline 5.
In order to form the ecological landscape effect, a stepped overflow weir 7 is arranged at the downstream of part of the dam body; in order to form a complete water surface at the stepped overflow weir 7, the overflow groove 6 is arranged at the outlet of the overflow pipeline 5, when water flow in the overflow groove 6 leaks downwards, a single water flow is converged into a water surface, the water surface flows to the downstream through the stepped overflow weir 7 to form wave-shaped water fall, and curtain-shaped water fall is formed at two sides of the step; the outlet of the overflow pipeline 5 is not provided with a step overflow weir 7 to form tap water, and the tap water, the wave-type water drop and the curtain-type water drop form a comprehensive landscape so as to achieve the purpose of combining ecological landscape and traffic on both banks.
