Description
Technical field
The utility model is related to Hydraulic Engineering Design technical field, especially a kind of flume steep slope section energy dissipater.
Background technology
With the rapid development of rural economy and social cause and the raising of environmental consciousness, more and more mountain villages abandon taking out
The water-supply method of underground water irrigate and drink is taken, but much original water-drawing channel has been unable to meet the people for wast rural area
The needs of masses' production, life, at the same it is long neglected and in disrepair, and water loss is larger, it is difficult to play the role of good diversion, it is in addition close several
The strong propulsion of year agricultural water conservancy project, more and more water diverting structures are built in rural area.Currently, rural area flume is mainly
Open channel diversion, but not can solve washing away of being generated when big flow high flow rate flow flows down, it needs to build in many cases
Large-scale energy dissipater carries out energy dissipating, constrains expanding economy in various degree.
Invention content
The technical problem to be solved by the utility model is to provide a kind of flume steep slope section energy dissipaters, can solve rural area
Flume can not solve the problems, such as that is generated when big flow high flow rate flow flows down washes away, and practicality, effect of energy dissipation is apparent, it is empty to save
Between；The faster mountain area water-drawing channel steep slope section of larger and flow rate of water flow especially suitable for water diversion flow.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of flume steep slope section energy dissipating
Work,
The setting pot on massif is cast in using coarse sand blinding concrete structure to be connected to stilling pond by the building that drops；
Setting pot is sequentially connected and is formed by diversion section, import linkage section, scour gallery section and outlet linkage section, and import connects
It connects and is provided with intake gate between section and scour gallery section；
It drops in building, the upper flume being connect with setting pot outlet linkage section is connected by energy dissipating ladder and lower flume
It connects；
Drop building and stilling pond both sides, which are built, stone masonry barricade.
Setting pot, drop building and stilling pond may be contained in coarse sand blinding concrete structure, coarse sand blinding concrete
Structure is made of coarse sand bed course and the reinforced concrete floor poured in coarse sand bed course upper surface.
Setting pot, drop building inner surface be both provided with epoxy mortar application layer.
Setting pot both sides are provided with Reinforced Concrete Retaining Walls.
Flume steep slope section energy dissipater provided by the utility model, the drop building using the form of ladder disappear
Can, energy dissipater increases the ladder that the mechanism of flow energy dissipating is mainly bottom surface " surface roughness " of bottom surface.Fall when flow flows through
When bank, on the one hand since ladder generates drop down stream, stable low pressure whirlpool is generated falling bank downstream inner;Another aspect ladder
Fall Kan Ding and constantly generate small whirlpool, and be involved in large quantity of air, thus exacerbate the turbulent fluctuation of flow, accelerates water turbulence boundary layer
Development fully blend the aerated flow for forming stabilization, canal bottom surface along Cheng Shuiqi and flow under the conditions of certain discharge per unit width
The depth of water increases, and flow velocity accordingly reduces, therefore the big energy for the flow that dissipated, and considerably increases down energy dissipation rate when letting out.Water body
Energy reduces, and is washed away to end cistern or field to reach reduction flow, reduces the size and grade of end energy dissipater.
In the dry season, maintenance and sand removal can be carried out by controlling intake gate.Stilling pond requirement is low, avoids big face
Long-pending excavation can be good at applying the original gradient of massif, can flexibly be applied in the larger flume section of the gradient, be one
The steep slope section flume form of economic, the efficient energy dissipating of kind.
Practicality, effect of energy dissipation is apparent, saves space；The faster mountain area of larger and flow rate of water flow especially suitable for water diversion flow
Water-drawing channel steep slope section, it is 1 to be commonly used in slope ratio:3-1:On 10 slope, water flow is up to 15 cubes of meter per seconds.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of the utility model setting pot.
Specific implementation mode
As depicted in figs. 1 and 2, a kind of flume steep slope section energy dissipater,
The setting pot 1 on massif is cast in using coarse sand blinding concrete structure by the building that drops to connect with stilling pond 2
It is logical；
Setting pot 1 is sequentially connected and is formed by diversion section 6, import linkage section 7, scour gallery section 8 and outlet linkage section 9,
Intake gate 10 is provided between import linkage section 7 and scour gallery section 8；
It drops in building, exports the upper flume 3 that linkage section 9 is connect with setting pot 1 and pass through energy dissipating ladder 4 and lower diversion
Canal 5 connects, and energy dissipating ladder 4 is convex-shaped；
Drop building and 2 both sides of stilling pond, which are built, stone masonry barricade 11.
Setting pot 1, drop building and stilling pond 2 may be contained in coarse sand blinding concrete structure, coarse sand bed course coagulation
Soil structure is made of coarse sand bed course 12 and the reinforced concrete floor 13 poured in 12 upper surface of coarse sand bed course.
Setting pot 1, drop building inner surface be both provided with epoxy mortar application layer.
1 both sides of setting pot are provided with Reinforced Concrete Retaining Walls 14.
The course of work of the utility model is as follows：
Energy dissipating is carried out using the drop building of the form of ladder, energy dissipater is mainly bottom surface to the mechanism of flow energy dissipating
Ladder increases " surface roughness " of bottom surface.When flow, which flows through, falls bank, on the one hand since ladder generates drop down stream, falling bank
Downstream inner generates stable low pressure whirlpool;Another aspect ladder falls Kan Ding and constantly generates small whirlpool, and is involved in large quantity of air, by
This exacerbates the turbulent fluctuation of flow, accelerates the development in water turbulence boundary layer, under the conditions of certain discharge per unit width, along Cheng Shuiqi
It is fully blended with flow and forms stable aerated flow, the canal bottom surface depth of water increases, and flow velocity accordingly reduces, therefore the flow that dissipated is big
Energy considerably increases down energy dissipation rate when letting out.The energy of water body reduces, to reach reduce flow to end cistern or
Person field is washed away, and the size and grade of end energy dissipater are reduced.
Setting pot 1 is designed using multistage, in the dry season, can carry out maintenance and sand removal by controlling intake gate 10.
Stilling pond 2 requires low, avoids the excavation of large area, can be good at applying the original gradient of massif, draws the gradient is larger
Water channel section can be applied flexibly, for a kind of steep slope section flume form of economic, efficient energy dissipating.
Practicality, effect of energy dissipation is apparent, saves space；The faster mountain area of larger and flow rate of water flow especially suitable for water diversion flow
Water-drawing channel steep slope section, it is 1 to be commonly used in slope ratio:3-1:On 10 slope, water flow is up to 15 cubes of meter per seconds.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the features in the embodiments and the embodiments of the present application in the absence of conflict, mutually can be combined arbitrarily.This practicality is new
