Description
Technical field
The present invention relates to hydraulic engineering technical field, in particular, relate to a kind of layering and take
Water checkdam.
Background technology
After Hydropower Plant Reservoir is built up now, reservoir waters is big, and has the biggest depth of water.Reservoir
Water temperature have significantly high along the feature of degree of depth stratification distribution, i.e. surface temperature, bottom
Water temperature is low.Surface temperature and bottom water temperature differ greatly, and temperature difference can reach 20 DEG C sometimes
Left and right.In order to when minimum generating water level, remain to get enough water yields, intake of hydropower station
It is generally arranged at lower position.But when high water level runs, now take out is then reservoir deep layer
Water body, temperature is relatively low, causes the index such as water temperature and oxygen content and former sky in downstream river course
So compare during river course and change greatly, and then downstream water environment and aquatile growth promoter are produced
Certain adverse effect.
Summary of the invention
The invention aims to overcome deficiency of the prior art, it is provided that a kind of stratified pumping
Checkdam, is arranged in the checkdam of the present invention appropriate location, reservoir upstream, can improve reservoir
In distribution of water temperature uneven, improve and under power station, let out water flow temperature, reduce downstream water environment
Adverse effect, have simple in construction, practical value is high, be prone to construction, reasonable in design, permissible
The advantage such as prefabricated.
It is an object of the invention to be achieved through the following technical solutions:
A kind of stratified pumping checkdam, described checkdam is by caisson, water bag, water pump and pressing plate structure
Becoming, described caisson is placed on the basis bottom riverbed as checkdam, by arranging horizontal stroke in caisson
Being formed with the cell for filling loads to longitudinal partition wall, described each cell top sets
Being equipped with inlet valve and outlet valve, described each caisson top is crimped with water bag by pressing plate, described
Being connected by water pipe between water bag, one end of water bag is provided with water pump, and the water bag other end is arranged
There is drain valve.
It is provided with hole on described partition wall.
Use bolt to fix between described pressing plate and caisson to be connected.
Described water bag is Water rubber bag.
Described loads is fine sand.
Described caisson is made up of concrete.
Compared with prior art, technical scheme is had the benefit that
1. the stratified pumping checkdam of the present invention, by being arranged in appropriate location, reservoir upstream, by
Sink under water in caisson, thus stop that the bottom water at low temperature in river, reservoir upstream flows into reservoir,
The current making skin temperature high pass through, and improve the temperature of warehouse-in current, make the water body temperature in reservoir
Degree raises, and then lets out water flow temperature under raising, alleviates the lower stream that sluices of generating to downstream river course temperature
With the impact of oxygen content, keep water environment equilibrium, the beneficially hydrobiological growth promoter in downstream；
Also can be according to the different river depth of water, this checkdam can be by the charge and discharge water of Water rubber bag
Adjust dam body height, it is ensured that superficial water passes through.
Caisset the most of the present invention can be prefabricated, and technique is simple, and speed of application is fast, underwater operation
Measure little, structural integrity good；Additionally, this checkdam can increase according to concrete actual flow width
Add deduct few caisset number, strong adaptability.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of stratified pumping checkdam, described checkdam by caisson 1,
Water bag 7, pressing plate 9 and water pump 11 are constituted, and caisson 1 is made up of concrete, and caisson 1 is laid
As the basis of checkdam bottom riverbed, according to the size dimension of caisson 1, set in caisson 1
Having put horizontal and vertical partition wall 2, thus defined cell 3, cell 3 is used for filling sand
Or other loads increase the deadweight of caisson 1, improve the stability of caisson 1；Each partition wall
All offer hole 4 on 2, in order to reduce the center of gravity of caisson 1, save simultaneously and manufacture caisson 1
The consumption of required concrete, the top of each cell 3 is provided with inlet valve 5 and outlet valve 6,
The top of caisson 1 there is also mounted water bag 7, and water bag 7 is the rubber bag of Water, water bag 7 it
Between be respectively connected with water pipe 8, water bag 7 is connected with caisson 1 by pressing plate 9, pressing plate 9 and sinking
Then using the fixing connection of bolt 10 between case 1, rear fender 9 tightened by bolt 10 enough pressures
Clamp force guarantees that water bag 7 does not falls out.The caisson 1 of side, riverbed is provided with and water bag 7 phase
The water pump 11 connected, the caisson 1 of riverbed opposite side is then provided with and is connected with water bag 7
Drain valve 12.
The concrete installation steps of the present invention are as follows:
(1) bank precast concrete caisson 1, and inlet valve 5 and outlet valve 6 are installed；
(2) Water rubber bag is installed, tightens the connecting bolt between pressing plate 9 and caisson 1
10, it is ensured that rubber water bag 7 will not be drawn out of；
(3) water pump 11 and drain valve 12 are installed at avris concrete caisson 1 top, and
Water pump 11 and the connecting tube of rubber water bag 7, drain valve 12 and the connecting tube of rubber water bag 7；
(4) connecting water pipe 8 between reserved good rubber water bag 7；
(5) inlet valve 5 and the outlet valve 6 of concrete caisson 1 are closed, by concrete caisson 1
Transportation by driving is to the position needing placement；
(6) loop wheel machine auxiliary, opens inlet valve 5 and outlet valve 6, by inlet valve 5 toward heavy
The inner water filling of case 1, when casing entirety gravity is slightly larger than buoyancy of water, closes inlet valve 5 and goes out
Mouth valve 6, sinks to specify position by caisson 1 by auxiliary loop wheel machine；
(7) open inlet valve 5 and outlet valve 6, be slowly injected into fine sand from inlet valve 5, with
Increase casing gross weight, reach design when requiring, close inlet valve 5 and outlet valve 6；
(8) connecting water pipe 8 between rubber water bag 7 is connected；
(9) water pump 11 is opened, water filling in rubber water bag 7, rubber water bag 7 can be filled
Play dash；Only need to open drain valve 12 during draining, rubber water bag 7 can be discharged water.
So can come by controlling the charge and discharge water of rubber water bag 7 according to the difference of the river course depth of water
Adjust the height of this checkdam, it is achieved stratified pumping.
As follows for the specification of the present invention being actually needed formulation, bed pattern is assumed to trapezoidal, river
Bed bottom width is 30m, and the depth of water is 30m, can design rectangular caisson 1, trapezoidal caisson 2,
Water rubber bag 3.Rectangular caisson length × width × height is 13m × 11m × 14m, front and rear wall
Thickness is 0.8m, and left and right sides wall thickness is also 0.5m, and partition wall thickness is 0.3m, front and back symmetrical point
