Abstract
The utility model belongs to field of hydraulic architecture, specifically discloses that a kind of draining is reliable and the preferable eulittoral zone gear discharge structure of positive water blocking effect.The eulittoral zone keeps off discharge structure and sets water blocking cover plate lid by the discharge ends upper cover in drainage channel, and keep the upper end of water blocking cover board and face near water hinged, therefore when side water level near water is higher than building behind water level, water blocking cover board is pressed on face near water and closes drainage channel by positive hydraulic pressure, avoids positive water flow from passing through drainage channel and enters in back slope Rock And Soil；When building behind water level is higher than side water level near water, reverse flow can pass through drainage channel and flow into side near water, so that reverse water pressure be effectively reduced；Meanwhile water blocking cover board degree of being turned over can be prevented by the way that opening adjustment mechanism is arranged on face near water, will not only interfere reverse drainage but also close water deflector cover sheet reset smoothly drainage channel after being conducive to reverse water pressure reduction, it ensure that reliability of operation.
Description
Technical field
The utility model belongs to field of hydraulic architecture, and in particular to a kind of eulittoral zone gear discharge structure.
Background technique
In the hydraulic structures such as all kinds of side slopes, dam body, barricade, channel abutment wall and channel revetment, building under normal conditions
Building object two sides has certain head, and with different operating conditions or natural rainfall situation etc., the height of two sides water level can be sent out
Changing even formation back-pressure, and back-pressure once being formed, its physico-mechanical properties parameter has after the Rock And Soil of back slope side is saturated
It is reduced, and reverse water pressure forms unfavorable load to related building, influences the security and stability of building, this is also many sides
The reason of slope is collapsed after lasting rainfall.
In order to reduce reverse water pressure, common practice is to add drainage hole in the eulittoral zone of hydraulic structure at present,
Though this way can comparatively fast reduce back-pressure, under positive pressure, water flow also inevitably enters back slope, leads to back slope rock
The physico-mechanical properties of the soil body reduce, it usually needs maintain its stabilization using the modes such as building cross dimensions are increased.In addition,
In part, the side slopes such as large channel building also apply non-return valve decompression, and non-return valve includes duck-beak type, pressure difference expansion formula etc.
Pattern, but the reliability of existing non-return valve is poor, silting or situations such as failure, happen occasionally in operation, and its positive water-retaining capacity
It is poor, it is only applicable to the case where head difference is lower than 20m.

Drawing piece is crossed to be connected with the lower end of water blocking cover board.
Further, the slide guide portion is the guide rail being arranged along the vertical direction, the sliding part is to be enclosed in lead
Ball in rail.
Further, the drawing piece be pull rod, the both ends of the pull rod respectively with the lower end of water blocking cover board and sliding
Part is hinged.
The beneficial effects of the utility model are: eulittoral zone gear discharge structure passes through in the discharge ends of drainage channel
Lid sets water blocking cover plate lid, and keeps the upper end of water blocking cover board and face near water hinged, therefore is higher than building behind in side water level near water
When water level, water blocking cover board is pressed on face near water and closes drainage channel by positive hydraulic pressure, avoids positive water flow from passing through draining logical
Road enters in back slope Rock And Soil；When building behind water level is higher than side water level near water, water blocking cover board under the action of reverse water pressure
Around its hinge point overturning near water on face to open drainage channel, and then reverse flow can pass through drainage channel inflow and face
Water side, so that reverse water pressure be effectively reduced；Meanwhile by the way that opening adjustment mechanism, opening adjustment mechanism energy is arranged on face near water
Enough limit water blocking cover board aperture so that water blocking cover board be in open extreme position when and the angle theta between face is less than near water
90 °, thus water blocking cover board degree of being turned over can be prevented, will not only interfere reverse drainage but also make water deflector cover after being conducive to reverse water pressure reduction
Sheet reset smoothly closes drainage channel, ensure that reliability of operation.
