Technical field
The utility model is related to agricultural irrigation technology, and in particular to a kind of unidirectional Auto-drainage of anti-seepage of channels lining cutting
Valve.
Background technology
Concrete lining is that current channel technological transformation adopts more engineering measure.Though rigid concrete face slab for water retaining has
Solve the anti-seepage of channels to effect, but while the row that also counteracts that underground water oozes out road, this can cause to act on canal bottom and canal slope
Uplift pressure is raised；Into after flood season, groundwater level is raised, and increases uplift pressure, and underground water counter plate produces extruding, in antiseepage
The weak spot (bottom root middle part, the height of side slope 2/3) of panel finally occurs the breakoff phenomenons such as panel spring, bulge cracking.
The content of the invention
Jacking destruction problem can be produced to central line tunnel concrete lining in south layer for underground water, the purpose of this utility model is to carry
For a kind of unidirectional automatic drain valve of anti-seepage of channels lining cutting.
The utility model solves the technical scheme that its technical problem adopted：The unidirectional Auto-drainage of anti-seepage of channels lining cutting
Valve, including plastic casing and the plastic top plate above plastic casing, the bottom of the plastic top plate passes through anti-aging rubber
Set is connected with plastic casing, and anti-aging rubber sleeve is provided with multiple spilled water holes, and the bottom of plastic top plate is provided with and plastic casing phase
The water stop rubber pad of adaptation, the upper level of plastic casing is provided with gripper shoe, and the bottom centre position of plastic top plate is provided with slip and leads
To axle, slide-and-guide axle is passed down through the center of gripper shoe and extends to inside plastic casing, and on slide-and-guide axle spring is arranged with,
Spring is located between plastic top plate and gripper shoe.
Specifically, the water stop rubber pad is located at the outside of anti-aging rubber sleeve.
Specifically, one end of the spring is connected with plastic top plate, and the other end is connected with gripper shoe.
Specifically, the bottom of the plastic casing is provided with screen pack.
Specifically, the anti-aging rubber sleeve is located at the outside of spring.
Specifically, the top of the plastic casing is located at anti-seepage of channels Concrete cover, during the bottom of plastic casing is located at
Coarse sand filter layer, the bottom of plastic casing is located at fine sand filter layer.
The utility model has the advantages that：The utility model have anti-aging, good toughness, corrosion-resistant, easy assembling,
The features such as reliability is high, energy Auto-drainage prevents canal for water conveyance jacking from destroying, time saving and energy saving, is widely portable to irrigation and water conservancy filling
Irrigate engineering.

Specific embodiment
The utility model is described in further detail presently in connection with accompanying drawing.
As Figure 1-3, the unidirectional automatic drain valve of anti-seepage of channels lining cutting, including plastic casing 7 and on plastic casing 7
The plastic top plate 1 of side, the bottom of the plastic top plate 1 is connected by anti-aging rubber sleeve 3 with plastic casing 1, anti-aging rubber
Set 3 is provided with multiple spilled water holes 9, and the bottom of plastic top plate 1 is provided with the water stop rubber pad 2 being adapted with plastic casing 7, plastic casing
7 upper level is provided with gripper shoe 5, and the bottom centre position of plastic top plate 1 is provided with slide-and-guide axle 6, and slide-and-guide axle 6 is downward
Center through gripper shoe 5 is extended to inside plastic casing 7, and spring 4 is arranged with slide-and-guide axle 6, and spring 4 is located at plastic top
Between plate 1 and gripper shoe 5.
Specifically, the water stop rubber pad 2 is located at the outside of anti-aging rubber sleeve 3.
Specifically, one end of the spring 4 is connected with plastic top plate 1, and the other end is connected with gripper shoe 5.
Specifically, the bottom of the plastic casing 7 is provided with screen pack 8.
Specifically, the anti-aging rubber sleeve 3 is located at the outside of spring 4.
Specifically, the top of the plastic casing 1 is located at anti-seepage of channels Concrete cover 10, the lower portion of plastic casing 7
In medium coarse sand filter layer 11, the bottom of plastic casing 7 is located at fine sand filter layer 12.
When channel water, the plastic top plate 1 of draining valve presses to the valve body of draining valve, until sealing under hydraulic pressure effect
Stop when rubber cushion 2 encounters valve body plastic casing 7, now plastics water stop rubber pad 2 can sealing, prevent the water of outside from into channel
After impervious concrete flaggy.When anhydrous in channel, when the water level after anti-seepage of channels Concrete cover 10 is higher, water is through medium coarse sand
Filter layer 11 and the two-layer of fine sand filter layer 12 are filtered, and reach unidirectional automatic drain valve, the bullet of water pressure and spring 4 in draining valve
Power jointly pushes open plastic top plate 1, and now the spilled water hole 9 on anti-aging rubber sleeve 3 discharges in water, gradually alleviates jacking force, most
The jacking force of outside is completely eliminated eventually.
