Embodiment 1

[0096] The embodiment of the present invention provides an earth dam structure with both traffic and flood discharge functions, such as Figure 1-4 shown, including:

[0097] Earth dam 1; preferably, the earth dam 1 is a homogeneous earth dam.

[0098] The dam body spillway 2, the dam body spillway 2 is arranged on the dam crest and the downstream slope of the earth dam 1;

[0099] The dam crest water passage 3 is arranged upstream of the dam crest of the earth dam 1 and is arranged in combination with the inlet section 21 of the dam body spillway 2 .

[0100] An earth dam structure with both traffic and flood discharge functions provided by the present invention can be used for earth dams whose dam height is not greater than 15m and has no bank spillway.

[0101] Preferably, the earth dam 1 includes a non-discharge dam section 11 and a flood discharge dam section 12, the flood discharge dam section 12 is located at the main river bed, and the dam crest and downstream slope ...

Embodiment 2

[0118] On the basis of Example 1, as Figure 5 As shown, a plurality of branch discharge pipes 7 are connected to different positions and directions on the drain pipe 26, and solenoid valves are arranged on the branch discharge pipes 7;

[0119] The water outlet of the branch discharge pipe 7 is connected with a first auxiliary device 4, and the first auxiliary device 4 includes:

[0120] The first connecting bracket 41 is connected to the lower end of the branched discharge pipe 7 near the water outlet of the branched discharge pipe 7;

[0121] The first shell 42 is connected to the lower end of the first connecting bracket 41;

[0122] The second connecting bracket 43 is connected to the side of the upper end of the first housing 42 close to the water outlet of the branch discharge pipe 7;

[0123] The first sliding rail 44 is arranged perpendicular to the branch discharge pipe 7 and is arranged through the second connecting bracket 43 and the first housing 42;

[0124] T...

Embodiment 3

[0139] On the basis of embodiment 1 or 2, as Figure 6-8 As shown, the present invention also discloses a construction device, which is used for the construction of the earth dam 1 structure with both traffic and flood discharge functions, including a rolling device 5, and the rolling device 5 includes:

[0140] The box body 51, the lower end of the box body 51 is provided with a moving wheel, and the box body 51 is provided with:

[0141] The cam 52 is rotatably connected in the box body 51 through a rotating shaft in the front-rear direction, and a drive motor for driving the cam 52 to rotate is arranged in the box body 51;

Abstract

The invention provides an earth dam structure with traffic and flood discharge functions and a construction device. The earth dam structure comprises an earth dam; the dam body spillway is arranged on the dam top and the dam downstream slope of the earth dam; and the dam crest water passing road is arranged on the upstream of the dam crest of the earth dam and is combined with the inlet section of the dam body spillway. The dam body spillway comprises an inlet section, a discharge chute section, a stilling pool section, a water interception tooth groove, a broken stone hardcore and a drainage pipe. The water passing road comprises a road and a downstream retaining wall. The method is used for an earth dam which is not provided with a shoreside spillway and has a traffic function on the dam crest, on one hand, the dam body spillway is additionally arranged, flood can be discharged from the dam crest, and therefore it is guaranteed that overtopping and burst of the dam cannot happen; and on the other hand, the dam crest is combined with the spillway inlet to arrange a water passing road, water passes during flood discharge and passes during no flood discharge, the problem that the dam crest cannot pass after flood discharge is additionally arranged is solved, and compared with a traffic bridge arranged at the dam crest, the structure is simpler, and the manufacturing cost is lower.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to an earth dam structure and a construction device with functions of traffic and flood discharge. Background technique [0002] In recent years, the phenomenon of overflowing the top of earth-rock dams has occurred from time to time. On the one hand, due to the frequent occurrence of extreme weather, local super-heavy rainstorms and super-standard flood events often occur, resulting in severe challenges for the safety of small reservoirs with low flood control standards during flood season; on the other hand, due to poor management and other reasons, flood discharge facilities are closed during flood season or blockage, resulting in flooding of the dam. [0003] In the construction of reservoirs in various countries, most of them use earth-rock dams. my country's reservoir earth-rock dams account for nearly 92%, and more than 50% of the dam fa...
