Detailed Description
The application is described in further detail below with reference to fig. 1-5.
The embodiment of the application discloses a dam flood control drainage structure. In this embodiment, the dam flood control drainage structure of the present application is applied to the dam of the reservoir 2. In other embodiments, the dam flood control drainage structure of the present application can also be applied to river dams.
Referring to fig. 1, the dike flood-control drainage structure includes a dike body 1, a flood discharge pipe 4, a water pipe 6, and a flood discharge gate 5. The flood discharge pipe 4 penetrates through the dam body 1, and the flood discharge pipe 4 communicates water bodies of the reservoirs 2 with the outside; the flood discharge gate 5 is movably connected with the dam body 1, and the flood discharge gate 5 is used for controlling the opening and closing of the flood discharge pipe 4. When the water level in the reservoir 2 rises to the early warning line, the worker opens the flood discharge channel of the dike through the flood discharge gate 5. The water in the reservoir 2 flows to the area outside the reservoir 2 through the flood discharge pipe 4. In the prior art, a plurality of modes can be adopted to realize that the flood discharge gate 5 controls the flood discharge pipe 4 to be opened and closed; therefore, the present embodiment does not expand the flood discharge gate 5 to control the opening and closing of the flood discharge pipe 4.
In this embodiment, the distance from the flood discharge tube 4 to the bottom of the dike body 1 increases in a direction away from the reservoir 2. The flood discharge pipe 4 arranged obliquely upwards discharges water upwards, so that the impact force of water pressure on the bottom of the dam can be relieved by using the high altitude.
The water delivery pipe 6 is arranged in the dam body 1, the water inlet end of the water delivery pipe 6 is communicated with the flood discharge pipe 4, the water outlet end of the water delivery pipe 6 is communicated with one side of the dam body 1 close to the water body, and the water outlet end of the water delivery pipe 6 is arranged at the right upper part of the water inlet end of the flood discharge pipe 4.
The water pipe 6 comprises a first pipe section 61 and a second pipe section 62 which are communicated, wherein the first pipe section 61 is communicated with the flood discharge pipe 4, and the second pipe section 62 is communicated with the reservoir 2. The water outlet end of the second pipe section 62 is positioned on the same vertical line as the water inlet end of the flood discharge pipe 4.
When the dam discharges the flood, part of water in the flood discharge pipe 4 flows upwards along the water delivery pipe 6; the portion of the body of water is ejected from and falls down the water outlet end of the second pipe section 62. The water outlet section of the water delivery pipe 6 is arranged right above the flood discharge pipe 4; the water body sprayed out and fallen from the second pipeline collides with the water body on the water inlet end of the flood discharge pipe 4, so that the water body on the upper side of the flood discharge pipe 4 is forced to move towards the periphery, and the dead tree trunk 3 on the upper side of the flood discharge hole is forced to move towards two sides, the occurrence of the condition that the dead tree trunk 3 blocks the flood discharge pipe 4 is reduced, and the flood control and drainage effect of a dyke is improved.
The inclined flood discharge pipe 4 can also improve the water quantity flowing into the conveying pipe and the water outlet speed of the conveying pipe; so as to further reduce the occurrence of the situation that the dried trunk 3 blocks the flood discharge pipe 4 and further improve the flood control and drainage capacity of the dykes and dams.
In order to further improve the impact of water flow sprayed by the water pipe 6 and water in the reservoir 2, the trunk of the withered tree 3 is forced to be far away from the flood discharge pipe 4 as far as possible, and the flood control and drainage capacity of the dam body is improved. This embodiment makes further modifications to the delivery tube.
In the present application, the first pipe section 61 is an arc-shaped pipe, the opening direction of the first pipe section 61 is set toward the reservoir 2, and the tangential direction of the water inlet end of the first pipe section 61 is set toward the reservoir 2. The water inlet of the first pipeline is obliquely arranged so that the water in the flood discharge pipe 4 flows into the conveying pipe, the water outlet speed of the second pipe section 62 is improved, and the impact strength of the sprayed water in the conveying pipe and the water in the reservoir 2 is improved.
Meanwhile, the distance from the second pipe section 62 to the bottom of the dike body 1 decreases in the direction away from the reservoir 2, i.e., the second pipe section 62 is disposed obliquely upward. The second pipe section 62 is inclined upwards to discharge water upwards, so that the impact effect of the water sprayed out of the water pipe 6 on the water body of the reservoir 2 can be improved; and then the water body on the upper side of the flood discharge pipe 4 moves to the periphery along with the dead trunk 3 for a longer distance, so that the situation that the flood discharge pipe 4 is blocked by the dead trunk 3 is further reduced.
In the embodiment, the dike body 1 is formed by casting concrete. The flood discharge pipe 4 and the delivery pipe can be made of steel pipes, corrugated pipes and the like. In this embodiment, the flood discharge tube 4 and the delivery tube are made of steel tubes.
Example 2
This embodiment 2 differs from embodiment 1 in that:
Referring to fig. 2, the water pipe 6 in this embodiment further includes a guide pipe section 63, one end of the guide pipe section 63 is communicated with the second section in opposite directions, and the other end of the guide pipe is communicated with the flood discharge pipe 4. In this embodiment, the second conduit is not required to be an arcuate tube. The inclined guide pipe section 63 facilitates the inflow of the ground water in the flood discharge pipe 4 into the delivery pipe, thereby improving the water outlet speed of the second pipe section 62.
Example 3
This embodiment 3 differs from embodiment 2 in that:
Referring to fig. 3 to 5, in the present embodiment, two water pipes 6 are provided, and the two water pipes 6 are disposed on both sides of the flood discharge pipe 4 in a staggered manner. Compared with the water delivery pipes 6 symmetrically arranged at two sides of the flood discharge pipe 4, the staggered water delivery pipes 6 can improve the water inflow of the two water delivery pipes 6 and the water outlet speed of the second pipe section 62.
Referring to fig. 4 and 5, in order to facilitate the exhibition of the cooperative relationship between the water pipe 6 and the flood discharge tube 4, the present embodiment separates the water pipe 6 and the flood discharge tube 4 from the dike body 1 for exhibition.
In this embodiment, the distance between the two second pipe sections 62 increases in a direction away from the reservoir 2, and the center extension 7 of the two second pipe sections 62 intersects the upper side of the reservoir 2. So that when the water bodies in the two second pipe sections 62 are sprayed out and fall to impact the water body of the reservoir 2, the surface water bodies between the central extension lines 7 are separated from other surface water bodies; thereby preventing the dry dead tree 3 floating in the reservoir 2 from drifting into the water above the flood discharge pipe 4. Namely, through the cooperative matching of the two water delivery pipes 6, the situation that the flood discharge pipe 4 is blocked by the dead tree trunk 3 is reduced, and the drainage stability of the flood discharge pipe 4 is improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
