The utility model discloses a dam crest is as floodgate dam structure of traffic bridge, absorption basin's head -end lies in the gate pier, and when the sluice earial drainage, the earial drainage can get into absorption basin very fast, forms stable disspation through hydraudic jimp, reaches the energy dissipation purpose of absorption basin design, and floodgate when reducing the sluice earial drainage simultaneously is the gate rapids vibration problem that causes of backward flow down.
Description
Technical field
This utility model relates to hydraulics dam energy-dissipating tech field, particularly relates to a kind of dam crest and is used as traffic
The gate dam structure of bridge.
Background technology
For dam crest is for the gate dam structure of access bridge, the usual more conventional lock of design length of gate pier section
Dam increased.When position of strobe is arranged, for ensureing under normal running (operation) conditions, make full use of gate pier and mix
The compressive property of solidifying soil, typically by gate locating at the upstream extremity of gate pier section.
Conventional gate locating is in the middle part of gate pier or the gate dam structure of middle and lower part, and going out water seal stream can quickly enter
Enter stiling basin, form stable disspation through hydraudic jimp, reach the energy dissipating purpose of stiling basin design.And for gate
From the point of view of the 12 gate dam structures being arranged on gate pier 11 upstream extremity, as it is shown in figure 1, go out water seal stream through certain
Stiling basin 13 is entered back into after the gate pier section of length, if the level of tail water is relatively low, then shape in stiling basin 13
Become disspation through hydraudic jimp；If the design level of tail water is of a relatively high, then under gate 12 goes out to flow relatively high thrust effect,
Bigger recirculating zone is formed on earial drainage top, and reflux intermittent beating gate 12, forms gate 12 earial drainage torrent
Vibration, easily causes gate 12 and damages.

Preferably, described apron is concrete apron or stone masonry apron.
Dam crest of the present utility model is used as the gate dam structure of access bridge, and the upstream extremity of stiling basin is positioned at gate pier,
When sluice earial drainage, earial drainage can quickly enter stiling basin, forms stable disspation through hydraudic jimp, reaches the power that disappears
The energy dissipating purpose of pond design, the gate torrent vibration caused that refluxes under lock when simultaneously reducing sluice earial drainage is asked
Topic.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the cross-sectional view of gate dam structure in prior art；
Fig. 2 is the cross-sectional view of the gate dam structure of this utility model one embodiment.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, existing comparison
Accompanying drawing describes detailed description of the invention of the present utility model in detail.
As in figure 2 it is shown, the dam crest of this utility model one embodiment is used as the gate dam structure of access bridge, including
Dam crest is used as the gate pier 2 of access bridge 21 and is used for the stiling basin 3 of energy dissipating.
Wherein, stiling basin 3 is connected to gate pier 2 downstream, and, the upstream extremity of stiling basin 3 is positioned at gate pier 2
In so that go out water seal stream after gate pier section, quickly enter stiling basin 3.For gate locating on gate pier 2
The situation of trip, when sluice earial drainage, earial drainage can quickly enter stiling basin 3, forms stable disspation through hydraudic jimp,
Reaching the energy dissipating purpose of stiling basin 3 design, reflux under lock when simultaneously reducing sluice earial drainage the gate caused
Torrent vibration problem.
In the present embodiment, the bottom surface 31 of stiling basin 3 upstream extremity is inclined-plane, this inclined-plane and the downstream of gate pier 2
Bottom surface connects.The base plate of stiling basin 3 is usually xoncrete structure, and bottom surface 31 structural strength on base plate is high.
This gate dam structure also includes maintenance gate slot 4 and the working gate slot 5 being arranged on gate pier 2 upstream extremity.Maintenance
Gate slot 4 and the parallel interval of working gate slot 5, and, maintenance gate slot 4 is positioned at the upstream of working gate slot 5,
That is: maintenance gate slot 4 is positioned at the working gate slot 5 side away from stiling basin 3.
On gate pier 2, maintenance gate slot 4 and working gate slot 5 are positioned at the outside as access bridge 21.Such as figure
Shown in 2, access bridge 21 correspondence is above the upstream extremity of stiling basin 3.
Additionally, this gate dam structure also includes being arranged on the first gate 6 bottom maintenance gate slot 4 and arranging
The second gate 7 bottom working gate slot 5.First gate 6 and the second gate 7 are respectively positioned on gate pier 2 upstream
End.When earial drainage opened by second gate 7, earial drainage can quickly enter stiling basin 3.
