The utility model can show the landscape effects of 'water curtain', 'curtain', etc. when reaching small flow by adjusting the structure of the spillway, which is more favorable for integrating the peripheral landscape and meets the needs of city development; and the purposes of flood discharge, energy dissipation and obvious energy dissipation effect are met at a high flow.
Description
Technical Field
The utility model relates to a view formula spillway structure belongs to hydraulic and hydroelectric engineering structural design field.
Background
At present, as a plurality of hydraulic and hydroelectric projects are closer to cities and even become important ecological nodes in the urban ecological space pattern, the construction of each building needs to be comprehensively considered by combining urban development, ecological health and landscape benefits.
The general water conservancy project needs to set water drainage energy dissipation buildings such as water drainage holes and spillways, landscape construction is carried out by combining water drainage channels, landscape effects of 'green bank and city landscape blending, water and harmony' can be achieved, especially for some spillways with small flow, large fall and long drainage channel, when a step-type landscape spillway is adopted, due to the longer water drainage channel, landscape effects of 'water curtain' and 'curtain' can be formed, the landscape can be more favorably integrated into the surrounding landscape, the requirement of city development is met, and the requirements of water drainage and energy dissipation can be met. The existing spillway with the smooth overflow surface has the defects of overhigh flow velocity in the deep contracted water, longer energy dissipater, larger investment and unobvious landscape effect.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a view formula spillway structure, this view formula spillway structure adopt the step discharge tank to let out large-traffic flood, forms the water jump type water tongue that incompletely or completely developed during the low discharge to form the view effect of "cascade", "heavy curtain".
The utility model discloses a following technical scheme can realize.
The utility model provides a landscape type spillway structure, which comprises a chute bottom plate; a plurality of uniformly distributed chute steps are arranged on the top surface of the chute bottom plate, a water inlet channel bottom plate is arranged at one end of the chute bottom plate, a stilling pool and a stilling pool tail ridge are sequentially arranged at the other end of the chute bottom plate, and stilling pool guide walls are arranged on two sides of the stilling pool; and the two sides of the discharge chute bottom plate are provided with discharge chute side walls.
And an overflow weir is arranged between the water inlet channel bottom plate and the drain tank bottom plate.
The elevation of the side wall of the draining groove is greater than the water surface line.
One end of the chute side wall is connected with the stilling pool guide wall, and the other end of the chute side wall is connected with the overflow weir gate pier.
The height of the stilling pool guide wall is greater than the water surface line.
The elevation of the step of the drainage groove is smaller than the water surface line.
The beneficial effects of the utility model reside in that: by adjusting the structure of the spillway, the landscape effects of 'water curtain', 'curtain', and the like can be presented when the flow is small, thereby being more beneficial to being integrated with the surrounding landscape and meeting the requirement of urban development; and the purposes of flood discharge, energy dissipation and obvious energy dissipation effect are met at a high flow.

Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is an enlarged view of the chute step of FIG. 1;
in the figure: 1-water inlet channel bottom plate, 2-overflow weir, 3-chute step, 4-chute bottom plate, 5-chute side wall, 6-water surface line, 7-stilling pool, 8-stilling pool tail ridge, 9-stilling pool guide wall and 10-overflow weir gate pier.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and 2, a landscape spillway structure includes a chute floor 4; the chute bottom plate 4 is arranged on a stable foundation, a plurality of chute steps 3 which are uniformly distributed are arranged on the top surface of the chute bottom plate 4, a water inlet channel bottom plate 1 is arranged at one end of the chute bottom plate 4, a stilling pool 7 and a stilling pool tail sill 8 are sequentially arranged at the other end of the chute bottom plate, and stilling pool guide walls 9 are arranged on two sides of the stilling pool 7; and the two sides of the discharge chute bottom plate 4 are provided with discharge chute side walls 5.
And an overflow weir 2 is arranged between the water inlet channel bottom plate 1 and the drain tank bottom plate 4.
The elevation of the chute side wall 5 is greater than the water line 6.
One end of the chute side wall 5 is connected with a stilling pool guide wall 9, and the other end is connected with an overflow weir gate pier 10.
The height of the stilling pool guide wall 9 is greater than the water surface line 6.
The height of the step 3 of the drainage groove is less than that of the water surface line 6.
Specifically, the height h of the spillway chute step 3 can be selected from 0.6m, 0.90m, 1.00m and 1.2m according to engineering experience and roller compacted concrete construction; the length L of the leakage groove is greater than L1+ L2.
To sum up, the beneficial effects of the utility model reside in that:
1. when the discharge amount is small, the landscape effects of a water curtain and a curtain can be formed, and the ornamental value is more excellent;
2. when the flood discharge is large, the flood discharge requirement can be met;
3. the friction on the discharge surface is large, the aeration is more, the energy dissipation effect is obvious, the size of an energy dissipater required by the downstream of the overflow dam is greatly shortened, and the engineering investment is reduced;
4. the flow velocity is reduced, and concrete with lower impact resistance requirement can be adopted as the overflow surface, so that the engineering investment is reduced;
5. the structure is simple in construction method, easy to master and easy to popularize.
