Brief description
Fig. 1 is used for the horizontal layout schematic diagram of the water intaking structure of the debris flow activity region hydraulic engineering for the present invention；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 1.
In figure is labeled as：Water intaking gallery grille bottom dam 1, water intaking aperture 2, drain grating bar 3, fixing device 4, grizzly bar are installed and are added
Gu frame 5, longitudinal bracing rail 6, horizontal reinforcing rail 7, pre-buried frame 8, link 9, dowel 10, bar batten 11, spacer bar 12.
Specific embodiment
As shown in Figure 1, Figure 2 and be that a kind of structure that the present invention provides is simple shown in Fig. 3, both make to send out due to flood season or mud-rock flow
The raw water intaking structure for the debris flow activity region hydraulic engineering also very easily water intaking gallery overhauled and managed.Institute
The water intaking structure stated includes water intaking aperture 2 and the drain grating bar being arranged on this water intaking aperture 2 on gallery grille bottom dam 1 of fetching water
3 it is characterised in that：Described water intaking structure also includes the fixing device 4 for fixing described drain grating bar 3, and described hurdle is dirty
Grizzly bar 3 is detachably arranged on described water intaking aperture 2 by described fixing device 4.Above by one fixation of setting
Device 4, described drain grating bar 3 is detachably arranged on described water intaking aperture 2 by described fixing device 4.This
Sample, had both made the flood season in the steeper mountain stream river course of channel gradient that mud-rock flow occurs, and the material blocking barrier carrying in current
Gap, it is also possible to very easily pull down described drain grating bar 3 from described water intaking aperture 4, is examined to water intaking gallery
Repair and manage, unlike in the prior art, due to being non-removable mounting structure, so that maintenance and management become very
Inconvenient.
In above-mentioned embodiment, in order to strengthen the intensity of described drain grating bar 3, in order to resist flood season or mud-rock flow in river course
The destruction that the withered tree that carries in current during generation, megalith cause to described drain grating bar 3 in flow at high speed, and then after improving
The maintenance of phase and management condition, water intaking structure described herein also includes grizzly bar and installs strengthening frame 5, is fixed on described grizzly bar peace
Described drain grating bar 3 on dress strengthening frame 5 is detachably arranged on described water intaking aperture 2 by described fixing device 4.
Now, the preferred structure that described grizzly bar installs strengthening frame 5 is by longitudinal bracing rail 6 and to be packed in described longitudinal bracing rail 6
On horizontal reinforcing rail 7 constitute, described drain grating bar 3 is arranged on described grizzly bar by described horizontal reinforcing rail 7
Install 5 on strengthening frame, it is solid by described longitudinal bracing rail 6 and described fixing device 4 that described grizzly bar installs strengthening frame 5
Fixed connection.The structure installing strengthening frame 5 with this grizzly bar is adapted, and now described fixing device 4 can adopt and include pre-buried frame 8
With the structure of the link 9 being detachably arranged on described pre-buried frame 8, described pre-buried frame 8 is packed in described water intaking aperture 2
In the concrete foundation of periphery, the two ends of the two ends of described drain grating bar 3 and described longitudinal bracing rail 6 are respectively fixed on institute
On the link 9 stated.As such, it is possible to strengthen the strength and stiffness of drain grating bar 3 to greatest extent, decrease drain grating bar and broken
Bad probability, is easy to later stage maintenance and manages.Further, in order to increase described pre-buried frame 8 in described water intaking aperture 2 periphery
The reliability being fixedly mounted with concrete foundation, described fixing device 4 also includes dowel 10, and described pre-buried frame 8 passes through described
Dowel 10 is packed in the concrete foundation of described water intaking aperture 2 periphery.
And in order to avoid cobble, gravel, sand, withered tree and the megalith especially cobble, the gravel that carry in current to greatest extent
Drain grating bar 3 described in stone and husky blocking, it is fixed by two pieces of bar battens 11 and one that described drain grating bar 3 is arranged to by the application
The structure that position reinforcing bar 12 is constituted, and the bar batten 11 described in two pieces is arranged on its cross section up big and down small chevron shaped
Structure, described spacer bar 12 is arranged in the opening of described chevron shaped structure along its length, and by this opening end seal
Close.So, along in water (flow) direction, the water gap excessively of described drain grating bar 3 just can form up-small and down-big flared structure,
As long as the upper surface of the drain grating bar 3 that the cobble carrying in current, gravel, sand, withered tree and megalith pass through, just can be directly entered
Without blocking drain grating bar 3 in water intaking gallery, it is particularly advantageous for passing through of silt, the avoiding of maximum limit delivers the stifled of dirty grizzly bar 3 for sale
Plug.Meanwhile, in order to avoid being hindered the cobble being relatively large in diameter connecing, gravel by drain grating bar 3, especially megalith is put and is stayed drain grating bar
Silt and the less cobble of diameter, the accumulation of gravel is caused, described water intaking aperture 2 is arranged and is in by the application on the whole on 3
The form of inclined downstream is arranged in the structure on described water intaking gallery grille bottom dam 1, and described drain grating bar 3 passes through described
Fixing device 4 be arranged on described water intaking aperture 2 with what described water intaking aperture 2 angle of inclination was adapted.So, in current
Carry just can not can move out described drain grating bar 3 with fast speed by drain grating bar 3 cobble, gravel and megalith,
The drain grating bar 3 that avoids of limits is blocked.
