Description
Technical field
The utility model relates to a kind of plate down-the-hole gate breather pipe structures, belong to hydraulic and hydroelectric engineering metal structure technology neck
Domain.
Background technique
For plate down-the-hole gate, especially main gate and emergency gate, snorkel should be set in principle after gate, this
It is mainly based upon improvement flow-shape, prevents cavitation corrosion, vibration, and reduce force of opening and closing etc. and require.After existing gate lintel
Snorkel is equipped in fist stage concrete.But for the sluicing of pressure slope structure or diversion tunnel is in top, then there is lintel section
Gas can not be supplemented and is discharged, this can induce radial gate vibration and aggravation lintel section cavitation corrosion, so the prior art or incomplete,
It needs to be further improved.
Utility model content
The purpose of this utility model is to provide a kind of plate down-the-hole gate breather pipe structures, to reduce radial gate vibration and door
Lintel section cavitation phenomenon occurs, and guarantees the safety of gate operation, thus overcome the deficiencies in the prior art.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of plate down-the-hole gate breather pipe structure of the utility model, including horizontal U-tube, U-tube both ends and lock
Door backbone side plate connection, air communication of the side at U-tube both ends through snorkel and lock underground trip outer edge surface.
In aforementioned structure, the cross sectional shape of the U-tube is the U-shaped structure that Open Side Down, and opening is inclined to gate direction
Tiltedly.
In aforementioned structure, the snorkel includes horizontally disposed L-type bend pipe and vertically disposed inverted L shape bend pipe, and L-type is curved
Pipe one end is connect with U-tube one end, and the L-type bend pipe other end is connect with inverted L shape bend pipe lower end, and the inverted L shape bend pipe other end is located at lock
Swim outer edge surface in underground.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model gate is in lintel
U-tube is arranged in lower end surface, and U-tube both ends can carry out gas to lintel section through snorkel and lock well downstream periphery and air communication
Supplement or discharge, reduce radial gate vibration and lintel section cavitation phenomenon occurs, and advantageously ensure that the safety of gate operation.This is practical new
Type is especially suitable for the sluicing that top is pressure slope structure or diversion tunnel.The method of the utility model is easy to implement, and structure is simple,
Construction cost is low.
Detailed description of the invention
Fig. 1 is the utility model snorkel arrangement schematic diagram；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the utility model breather pipe structure schematic diagram.
The label in accompanying drawing is: 1- lintel, 2- U-tube, 3- gate backbone side plate, 4- L-type bend pipe, 5- lock wall, 6- inverted L
Type bend pipe, 7- lock well downstream periphery, 8- snorkel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The utility model is to be constituted according to a kind of improved method of following plate down-the-hole gate snorkels and be used for this
Method, as shown in Figure 1 to Figure 3: this method is that a horizontal U-tube 2 is arranged in 1 lower end surface of lintel, and 2 both ends of U-tube are logical
It crosses horizontally disposed L-type bend pipe 4 to lead in lock wall 5, and is connect with 6 lower end of inverted L shape bend pipe in lock wall 5, inverted L shape bend pipe 6
Outlet is located at lock underground trip outer edge surface 7 and air communication；By U-tube 2 to 1 section of progress gas supplement of lintel or discharge, reduce
Radial gate vibration and lintel section cavitation phenomenon occur, to guarantee the safety of gate operation.The cross sectional shape of U-tube 2 is that Open Side Down
U-shaped structure, opening to gate direction tilt.
According to a kind of plate down-the-hole gate breather pipe structure of the utility model that the above method is constituted, such as Fig. 1 to Fig. 3 institute
Show: including horizontal U-tube 2,2 both ends of U-tube are connect with gate backbone side plate 3, the side at 2 both ends of U-tube through snorkel 8 and
The air communication of lock underground trip outer edge surface 7.The cross sectional shape of U-tube 2 is the U-shaped structure that Open Side Down, and opening is to gate side
To inclination.Snorkel 8 include horizontally disposed L-type bend pipe 4 and vertically disposed inverted L shape bend pipe 6,4 one end of L-type bend pipe with it is U-shaped
The connection of 2 one end of pipe, 4 other end of L-type bend pipe are connect with 6 lower end of inverted L shape bend pipe, and it is outer that 6 other end of inverted L shape bend pipe is located at the trip of lock underground
Edge face 7 and air communication.
Embodiment
It is the sluicing of pressure slope structure or diversion tunnel due to being architectural limitation for top, it can not be using the logical of the prior art
Stomata, this example are mainly used in the plate down-the-hole gate of the sluicing that top is pressure slope structure or diversion tunnel, when it is implemented, first
With steel plate by one U-tube 2 of production as shown in Figure 3.The cross sectional shape of U-tube 2 is the U-shaped structure that Open Side Down, opening to
The inclination of gate direction.Then 2 both ends of U-tube and gate backbone side plate 3 are welded and fixed, then make two as schemed using steel pipe
The side at snorkel 8 shown in 3,8 lower end of snorkel and 2 both ends of U-tube is welded, and 8 upper end of snorkel is located at lock well downstream periphery
Face 7 and air communication.When carrying out pouring the fist stage concrete of gate, snorkel 8 is cast in the lock wall 5 of gate.Ventilation
Pipe 8 includes horizontally disposed L-type bend pipe 4 and vertically disposed inverted L shape bend pipe 6, and 4 one end of L-type bend pipe is connect with 2 one end of U-tube,
4 other end of L-type bend pipe is connect with 6 lower end of inverted L shape bend pipe, and 6 other end of inverted L shape bend pipe is located at lock underground trip outer edge surface 7 and air
Connection.
This example carries out gas supplement or discharge to lintel section by snorkel 8, reduces radial gate vibration and lintel section cavitation corrosion is existing
As occurring, the safety of gate operation is advantageously ensured that.
