Description
Technical field
The utility model relates to the side slope elevation devices before a kind of reservoir dam spillway.
Background technique
The Chinese invention patent of Patent No. CN201410177457.X disclose " reservoir dam overflow flood movable block fish
Device ", notification number CN103918591B.The device is typically mounted in reservoir dam spillway, but some reservoirs due to by
Various factors limit and can not be mounted in spillway: as spillway stroke is short or overflow flood when to reservoir mention lock have an impact without
It can installation；The turbulent river crashes its way through when besides big vast since reservoir dam spillway overflows, and the fish that device for blocking fish stops much closes in online shape
At immense pressure, when overflowing big vast, device for blocking fish, which blocks fish effect, just will be greatly reduced.Therefore, device for blocking fish must be just mounted on the flood that overflows
The forward as far as possible and outer position in road, the positional distance spillway is remote and water level is deep, has dispersed water flow, and water flow is more relaxed
Delay, avoid the problem of fish closes barrier net when blocking fish.
It is all the rubble and ground that construction leaves due to being essentially all side slope landform before reservoir dam spillway, in side slope
Shape complexity is not flat enough, causes difficulty to installation device for blocking fish.Side slope before spillway must be raised to the water of spillway
Flat height, is just able to satisfy installation requirement, so that opening and closing can be played the role of at any time by overflowing when flood blocks fish in reservoir.But
Side slope landform is deeper than spillway, and the side slope having is also all the year round under water, and constructional difficulties are complicated.
Utility model content
In order to solve above-mentioned drawback, reservoir dam is overflow technical problem to be solved by the utility model is to provide a kind of
The device that side slope before big vast road is raised, so that side slope is raised to the level height of spillway, in order to install device for blocking fish.In order to
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is the side slope elevation device before reservoir dam spillway,
It is characterized in that, the crossbeam of the armored concrete including being fixed on side slope bank；It further include the weight base of several armored concrete
Seat, several weight pedestals are lined up in the side slope that linear type sinks under the water；One is fixed on each weight pedestal oblique to stretch
The connection girder steel being arranged out and a vertical support steel beam for stretching out setting, all affixed cross in extension end of each connection girder steel
Beam, all affixed lateral girder steel in the extension end of each support steel beam；Steel grid plan is equipped between the crossbeam and lateral girder steel；
The bottom surface of the steel grid plan and spillway is located at same level.
The beneficial effects of the utility model are that the side slope elevation device is simple and reasonable, are not only convenient for device for blocking fish
Installation and effective use, and the installation maintenance of ontology is easy to use, firm in structure durable, effectively releived excessive flood when block fish
The water flow of device does not influence the flood that overflows, it is ensured that safety.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is further described in detail the utility model.

Fig. 3 is the overall structure diagram of 1 elevation device of embodiment (device is arranged in right bank, no device for blocking fish)；
Fig. 4 is the overall structure diagram of 2 elevation device of embodiment (device is arranged in left bank, there is device for blocking fish)；
Fig. 5 is the overall structure diagram of 3 elevation device of embodiment (device is arranged in left bank, no device for blocking fish).
Specific embodiment
Embodiment 1: referring to attached drawing 1-3, reflect a kind of specific structure of the utility model, the spillway of the reservoir dam
The elevation device of the side slope 9 of 1 front, the crossbeam 8 of the armored concrete including being fixed on 9 bank of side slope；It further include three reinforcing bars
The weight pedestal 4 of concrete, three weight pedestals 4 are lined up linear type and are sunk in side slope 9；It is fixed on each weight pedestal 4
A piece oblique connection girder steel 7 for stretching out setting and a vertical support steel beam 3 for stretching out setting, three on three weight pedestals 4
Root connects all affixed crossbeam 8 in extension end of girder steel 7, all affixed lateral girder steel 2 in the extension end of three support steel beams 3；It is described
Steel grid plan 6 is abound between crossbeam 8 and lateral girder steel 2；The bottom surface of the steel grid plan 6 and spillway 1 is located at same
One horizontal plane.
By adopting the above technical scheme, sequence of construction method, which may is that, pulls in shore to pour fixed certain length first in side slope 9
Armored concrete crossbeam 8, reserved steel bar welding point on crossbeam 8.
Three prefabricated weight pedestals 4 linear type is lined up again to sink in side slope 9.The connection girder steel 7 of weight pedestal 4 is logical
It crosses welding and cement fixation is affixed with the crossbeam 8, play fixed weight pedestal 4.On support steel beam 3 connects vertically upward
The lateral girder steel 2 of external peripheral is leaned in face；Grid plan 6, and net are welded into reinforcing bar and girder steel 5 between lateral girder steel 2 and crossbeam 8
The bottom surface of lattice plane 6 and spillway 1 is located at same level, not only convenient for being connected cooperation with barrier net 10 for blocking fish, and
There is no resistance to water flow when overflowing big vast, so not influencing on the excessive flood of reservoir dam.The specific knot of barrier net 10 and its device for blocking fish
The Chinese invention patent of structure and working method referring to Patent No. CN201410177457.X, the title " work of the excessive flood of reservoir dam
Dynamic formula device for blocking fish ", notification number CN103918591B, repeats no more.
When reservoir dam overflows big vast, when water flow passes through the side slope elevation device, because bottom surface is steel grid plan, to water flow
There is no resistance, so not influencing on excessive flood, it is ensured that safety.
As shown in figure 3, the structure when (right bank) on the opposite bank is arranged in above-mentioned apparatus is in symmetrical with the structure that left bank is arranged in
Shape repeats no more.
Embodiment 2: as shown in figure 4, difference from example 1 is that, barrier net is by blocking fish A net 11 and blocking fish B net
12 compositions, fixed column can be equipped with by blocking fish A net 11 with the dog-ear portion for blocking fish B net 12, be blocked fish A net 11 or be blocked fish B net 12
Be hinged on column, convenient for opening or closing.
Embodiment 3: as shown in figure 5, difference from example 1 is that, the oblique linear type of lining up of weight pedestal 13 sinks
Enter in side slope 14, sinkage is gradually increased, and grid plan 15 is triangular in shape.
Above-mentioned implementation is merely to clearly illustrate the technical solution of the utility model, and should not be understood as to this
Utility model makes any restrictions.The utility model has well known a variety of substitutions or deformation in the art, is not taking off
Under the premise of from the utility model in essence meaning, the protection scope of the utility model is each fallen within.
