The specific embodiment
For the technical problem that the present invention is solved, the technical scheme of employing, the technique effect of obtaining should be readily appreciated that below in conjunction with concrete accompanying drawing, specific embodiments of the invention is done further explanation.
Like Fig. 1, shown in Figure 2, lock of the present invention weir comprises the weir body, and bottommost is stamped one deck concrete, and the bed course that rubble etc. constitute is the base plate 7 of weir body above the bed course, and said base plate 7 is the foundation to protect part of structure of the present invention, adopts steel concrete to make up.Both sides are steel concrete side walls, limit the width on lock weir according to the different geographic environment, keep the resistance to overturning of structure.
On base plate 7, be horizontally arranged with the overflow waterwall 1 of one steel concrete structure, when the water level of right side current 110 was higher than the top of overflow waterwall 1,110 in current can flow to the left side from the top of overflow waterwall 1, thereby realized the excessive flood effect on lock weir.The height of overflow waterwall 1 carries out calculation Design according to different on-the-spot water level situation, the resistivity on lock weir.Overflow waterwall 1 is provided with the dewatering orifice, is used for initiatively discharging water.Said dewatering orifice can be the starting and stopping type dewatering orifice, also can be the duct of gate valve type dewatering orifice or other modes.What present embodiment adopted is the gate valve type dewatering orifice, comprises adjutage 2 and adjutage gate valve 3, and said adjutage 2 passes overflow waterwall 1, can release the current above adjutage 2 bottom tube height.Adjutage gate valve 3 not only can be controlled the open and close of adjutage 2, but also can control to adjust the flow when passing adjutage 2, has realized the function that initiatively discharges water on lock weir.The position of adjutage 2 on overflow waterwall 1 preferably makes the bottom tube of adjutage 2 and on-the-spot lowest water level line (level of dead water) flush.The structure of adjutage 2 and adjutage gate valve 3 is common practise, the conventional design in present technique field, no longer specifies at this.
The power that disappears bank is claimed disspation through hydraudic jimp again, and through hydraulic jump, the torrent that outlet structure escape works are released changes unhurried current into, to eliminate the energy dissipating mode of kinetic energy.Energy dissipation by hydraulic jump mainly lean on the surface roller that hydraulic jump produces and revolve roll and underflow between strong turbulent fluctuation, shearing and blending effect.It has fluid stable, and effect of energy dissipation is better, and is strong to geological conditions and tail water luffing compliance, and the tail water fluctuation is little, advantages such as maintenance cost province.But protection-apron is longer, and earthwork evacuation amount and concrete square amount are bigger, and construction costs is higher.Upper pond level is big to the drop of the first section that jumps, so it is high to locate flow velocity, when Froude number Fr was low, the kinetic energy of dissipation was few, and promptly complementary energy is many, and complementary energy mainly is exactly the potential energy that the depth of water is expressed after jumping.Energy dissipation by hydraulic jump is used very wide, is suitable for high, medium and low head, all kinds of outlet structure escape works of large, medium and small flow.
Lock of the present invention weir preferably makes up the power bank 6 that disappears together in the left side of overflow waterwall 1, can be the power that the disappears bank of laying with mountain stone, also can be steel concrete.The side wall of the power that disappears bank 6, base plate 7, both sides, overflow waterwall 1 surround an absorption basin, prevent that the impulse force that adjutage 2 effluents, flood is overflow at overflow waterwall 1 top is excessive, and periphery is damaged.A starting and stopping type dewatering orifice of being made up of gutter 4 and gutter gate valve 5 is set in the lower end of the power bank 6 that disappears, can discharges the water in the absorption basin in Artificial Control ground.The position of gutter 4 on the power bank 6 that disappears can be the bottom that places the power bank 6 that disappears, and also can be apart from base plate 7 certain height.
Preferably, the top of body is provided with an access bridge 9 on the weir, and access bridge 9 is laid on the top of side wall, has not only made things convenient for traffic, but also can hidden flood spillway, in the flood that overflows, also can play certain sound deadening, has ensured the safety on lock weir.
Preferably, on the right side of access bridge 9 breastwork 8 can also be set, breastwork 8 and access bridge 9 right sides are vertical to be connected and to extending below, the effect of breastwork 8 mainly is the floating thing in the block water when overflowing flood, is convenient to clear up the rubbish on the water surface.When water level was higher, breastwork 8, side wall, access bridge 9 were hidden with flood spillway, can reduce the sound of current when overflowing flood.
The method for using on lock of the present invention weir is following: end timestamp in the water level on right side, lock weir is higher than the pipe of adjutage 2, and can control through adjutage gate valve 3 and whether discharge water.If when right side, lock weir water level elevation was higher than the top board elevation of the power bank 6 that disappears, gutter gate valve 5 can be closed, water flows out from the top of the power bank 6 that disappears; Otherwise gutter gate valve 5 need be opened, and could cooperate adjutage 2 to discharge water.
When if water level is higher than the top of overflow waterwall 1, current flow out from the top of overflow waterwall 1 automatically, after the absorption basin that overflow waterwall 1, the power that disappears bank 6, side wall, base plate 7 surround carries out energy dissipating, flow out from the top of the power bank 6 that disappears.
Certainly, in special environment, if the water level in left side, lock weir is higher than the right side, when being higher than the invert elevation (IE) journey of adjutage 2 simultaneously, the water in left side can be through gutter of opening 4 and the adjutage 2 inflow right sides of opening.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should belong to technological category of the present invention.
