Description
Technical field
The utility model relates to a kind of hydraulic engineering field more particularly to a kind of overfall dams.
Background technique
Overfall dam (overflow dam), dam crest can flood discharge dam, also known as overflow dam.Overfall dam is generally by concrete or slurry
Stone-laying is built up.There are overflow gravity dam, overflow arch dam, overflow buttress dam and overflow earth and rockfill dam by dam type.The latter is only limitted to spillwag chute
The weir for having reliable protection facility, discharge per unit width smaller with base of dam.It is combined together with workshop, the dam as flood releasing structure
Interior formula workshop overfall dam, overflow type and the factory's dam joint flood discharge mode for choosing more workshop top aerial drainage, can used in high mountain glen
Area is to solve spillway and a kind of insufficient approach of Power Plant position, and develop from overfall dam when leading big flow off
The new model to get up, but overfall dam drains inconvenience, easily causes danger in rainwater season at present when urban river water flow is big.
Utility model content
The purpose of this utility model is to provide a kind of overfall dams, to solve the above technical problems.
The utility model uses a kind of following technical scheme: overfall dam, comprising: blinding layer, kind to achieve the above object
Soil, vegetation, gate, dam body, Landscape stone, bolt hole, screw rod, turntable, geotextile layer are planted, the top layout of the blinding layer has
Planting soil, on planting soil, the gate installation is mounted on gate in the top of blinding layer, the dam body for the vegetation plantation
Top, the Landscape stone is arranged on dam body, and the geotextile layer is arranged in the bottom of Landscape stone, and the bolt hole is provided with
The inside of dam body, the bottom of the turntable are equipped with screw rod, inside and gate phase of the screw rod by bolt hole through dam body
Connection.
On that basis of the above technical scheme, the inside of the blinding layer is disposed with reinforcing bar.
On that basis of the above technical scheme, the gate is divided into upper and lower two parts, and top is big, and lower part is small, and top is sky
Core structure, by rotary turnplate, screw rod rises, and lower part gate follows screw rod to rise, and takes in the inside on gate top.
On that basis of the above technical scheme, the bolt hole is disposed with screw thread.
On that basis of the above technical scheme, the dam body is concrete material, is disposed with reinforcing bar.
Compared with prior art, the utility model has the advantage that the utility model is equipped with gate, big in water flow
When open, can be avoided and cause danger, be disposed with waterproof geotextiles, protect concrete dam body, bottom plantation has vegetation,
Soil erosion is prevented while beautiful again.
Detailed description of the invention
Fig. 1 is the overfall dam schematic diagram of the utility model.
Fig. 2 is the gate schematic diagram of the utility model.
Fig. 3 is the gate opening state figure of the utility model.
Fig. 4 is the dam body sectional view of the utility model.
In figure: 1, blinding layer, 2, planting soil, 3, vegetation, 4, gate, 5, dam body, 6, Landscape stone, 7, bolt hole, 8, spiral shell
Bar, 9, turntable, 10, geotextile layer.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of overfall dam, comprising: blinding layer 1, planting soil 2, vegetation 3, gate 4,
The top layout of dam body 5, Landscape stone 6, bolt hole 7, screw rod 8, turntable 9, geotextile layer 10, the blinding layer 1 has planting soil
2, the plantation of vegetation 3 is on planting soil 2, and the gate 4 is mounted on the top of blinding layer 1, and the dam body 5 is mounted on gate
4 top, the Landscape stone 6 are arranged on dam body 5, and the geotextile layer 10 is arranged in the bottom of Landscape stone 6, the bolt hole
7 are provided with the inside of dam body 5, and the bottom of the turntable 9 is equipped with screw rod 8, and the screw rod 8 is by bolt hole 7 through dam body 5
Inside is connected with gate 4, and the inside of the blinding layer 1 is disposed with reinforcing bar,
The gate 4 divides for upper and lower two parts, and top is big, and lower part is small, and top is hollow structure, passes through rotary turnplate
9, increase screw rod 8, lower part gate follows screw rod 8 to rise, and takes in the inside on gate top, the bolt hole 7 is disposed with spiral shell
Line, the dam body 5 are concrete material, are disposed with reinforcing bar.
The utility model is equipped with gate, opens when water flow is big, can be avoided and causes danger, and is disposed with waterproof
Geotextiles, protect concrete dam body, and bottom plantation has vegetation, prevents soil erosion while beautiful again.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired
Change, replacement and variant is still fallen within the protection scope of the utility model.
