Be labeled as in figure: water intaking gallery grille bottom dam 1, water intaking aperture 2, drain grating bar 3, fastening devices 4, grizzly bar install strengthening frame 5, longitudinal bracing rail 6, horizontal reinforcing rail 7, pre-buried frame 8, link 9, dowel 10, bar batten 11, spacer bars 12.
Detailed description of the invention
As shown in Figure 1, Figure 2 and be that a kind of structure provided by the invention simply, had both made because flood season or mud-rock flow occur also very easily to the water intaking structure for the debris flow activity region hydraulic engineering that water intaking gallery overhauls and manages shown in Fig. 3.The drain grating bar 3 that described water intaking structure comprises the water intaking aperture 2 on water intaking gallery grille bottom dam 1 and is arranged on this water intaking aperture 2, it is characterized in that: described water intaking structure also comprises the fastening devices 4 for fixing described drain grating bar 3, and described drain grating bar 3 is arranged on described water intaking aperture 2 by described fastening devices 4 is dismountable.Above by arranging a fastening devices 4, described drain grating bar 3 is arranged on described water intaking aperture 2 by described fastening devices 4 is dismountable.Like this, both made, in the flood season in channel gradient steeper mountain stream river course, mud-rock flow occurs, there is the material blocking barrier gap of carrying in current, also can very easily described drain grating bar 3 be pulled down from described water intaking aperture 4, water intaking gallery is overhauled and managed, unlike in the prior art, owing to being non-removable mounting structure, thus maintenance and management is made to become very inconvenient.
In above-mentioned embodiment, in order to strengthen the intensity of described drain grating bar 3, in order to resist carry in current when flood season in river course or mud-rock flow occur withered tree, megalith in flow at high speed to the destruction that described drain grating bar 3 causes, and then improve maintenance and the management condition in later stage, water intaking structure described in the application also comprises grizzly bar and installs strengthening frame 5, and the described drain grating bar 3 be fixed on described grizzly bar installation strengthening frame 5 is arranged on described water intaking aperture 2 by described fastening devices 4 is dismountable.Now, the preferred structure that described grizzly bar installs strengthening frame 5 is be made up of longitudinal bracing rail 6 and the horizontal reinforcing rail 7 be packed on described longitudinal bracing rail 6, described drain grating bar 3 is arranged on described grizzly bar by described horizontal reinforcing rail 7 and installs on strengthening frame 5, and described grizzly bar is installed strengthening frame 5 and is fixedly connected with described fastening devices 4 by described longitudinal bracing rail 6.The structure of grizzly bar installation strengthening frame 5 is suitable therewith, now described fastening devices 4 can adopt the structure comprising pre-buried frame 8 and dismountable link 9 be arranged on described pre-buried frame 8, described pre-buried frame 8 is packed in the concrete foundation of described water intaking aperture 2 periphery, and the two ends of described drain grating bar 3 and the two ends of described longitudinal bracing rail 6 are fixed on described link 9 respectively.Like this, the strength and stiffness of drain grating bar 3 can be strengthened to greatest extent, decrease the probability that drain grating bar is destroyed, be convenient to later stage maintenance and management.Further, in order to increase the reliability that described pre-buried frame 8 is fixedly mounted with in the concrete foundation of described water intaking aperture 2 periphery, described fastening devices 4 also comprises dowel 10, and described pre-buried frame 8 is packed in the concrete foundation of described water intaking aperture 2 periphery by described dowel 10.
And in order to avoid cobble, gravel, sand, withered tree and the megalith drain grating bar 3 especially described in cobble, gravel and husky blocking carried in current to greatest extent, described drain grating bar 3 is arranged to the structure be made up of two pieces of bar battens 11 and a spacer bars 12 by the application, and the bar batten 11 described in two pieces is arranged to up big and down small chevron shaped structure on its cross section, described spacer bars 12 is arranged in the openend of described chevron shaped structure along its length, and is closed this openend.Like this, 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 carried in current, gravel, sand, withered tree and megalith pass, just directly can enter in water intaking gallery and drain grating bar 3 can not be blocked, especially be beneficial to passing through of silt, maximum limit avoid the blocking of delivering dirty grizzly bar 3 for sale.Simultaneously, in order to avoid being hindered the diameter that connects larger cobble, gravel by drain grating bar 3, especially megalith puts the accumulation of staying and drain grating bar 3 causing silt and the less cobble of diameter, gravel, described water intaking aperture 2 is arranged the structure of arranged in form on described water intaking gallery grille bottom dam 1 in inclined downstream by the application on the whole, and what described drain grating bar 3 was adapted with angle of inclination, described water intaking aperture 2 by described fastening devices 4 is arranged on described water intaking aperture 2.Like this, carry in current not by drain grating bar 3 cobble, gravel and megalith just can fast speed move out described drain grating bar 3, avoid drain grating bar 3 to greatest extent blocked.
