Based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description rather than instruction or dark
Show that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that right
The limitation of the present invention.
As shown in Figure 1 and Figure 2, limiting valve type exhaust outlet device provided in this embodiment includes the valve body 2 of hollow setting,
Valve body 2 sequentially passes through gas collection ponding layer 10, ground layer 20, firming layer 30 and water layer 40, ground layer 20 and firming from the bottom to top
Antiseepage film 31 is equipped between layer 30；Valve body 2 has been nested with limiting air bleeding valve, limiting air bleeding valve can according to 31 top of antiseepage film and
The variation of pressure differential between the medium of lower section switches between opening and closed state automatically, so as to automatic effective
Gas under film is discharged, prevents gas bursting under the membrane body envelope of antiseepage film 31, while cause the device that there is good automatic row
Gas draining and effect of easing stress；The apparatus structure is simple, convenient for production, safe and reliable and convenient for construction, since the device is embedded in water
Under, it did not only affect the appearance, but also can realize the Auto-drainage degassing function under antiseepage film 31 well.
In the present embodiment, by medium (mixture of such as gas or gas and water) preset threshold pressure of 31 lower section of antiseepage film
Force value, when the pressure value of the medium of 31 lower section of antiseepage film is more than critical pressure value, limiting air bleeding valve is in opening；Antiseepage
When the pressure value of the medium of 31 lower section of film is less than or equal to critical pressure value, limiting air bleeding valve is closed.
The limiting air bleeding valve of the present embodiment includes spool 3 and gas vent 4, is equipped with a through-hole in valve body 2, spool 3 is set in
In through-hole, gas vent 4 is set to the bottom of spool 3.It is preferred that when limiting air bleeding valve and being in opening, spool 3 and through-hole
There are an air channels, gas vent 4 between inner wall to connect with air channel；When limiting air bleeding valve and being closed, spool 3 and logical
It is tightly connected between the inner wall in hole.
In order to ensure to limit air bleeding valve can better automatic exhaust outlet, the preferably longitudinal section of spool 3 is I-shaped,
Upper and lower ends are respectively equipped with end face boss, and two end face boss pass through center axis connection, the diameter difference of two end face boss
More than the diameter of central shaft；Through-hole top in valve body 2 is equipped with a groove, the groove and the end face boss pair of 3 upper end of spool
It should set, multiple gas vents 4 are uniformly equipped on the end face boss of 3 lower end of spool.
When the pressure value of the medium of 31 lower section of antiseepage film is more than critical pressure value, the pressure medium below antiseepage film 31
Under effect, spool 3 is jacked up upwards, i.e. the end face boss of 3 upper end of spool is detached with groove, forms air channel between the two, into
And so that gas vent 4 is connected with air channel, and so as to which limiting air bleeding valve be made to be in opening, the medium below antiseepage film 31 at this time
Into after valve body 2, sequentially through the gas vent 4 and air channel on the end face boss of 3 lower end of spool, i.e., across limiting air bleeding valve,
Then it is automatically drained out via the outlet of valve body 2.
When the pressure value of the medium of 31 lower section of antiseepage film is less than or equal to critical pressure value, the medium of 31 lower section of antiseepage film
Pressure effect can not be jacked up spool 3, under the self gravitation effect of spool 3, the bottom surface point of the end face boss of 3 upper end of spool
It is not tightly connected with the upper surface of the inner wall of through-hole and groove, so as to be closed limiting air bleeding valve, illustrates to prevent at this time
Gas or the storage of gas and water for oozing 31 lower section of film are still few, it is not necessary to discharge.
The sundries such as mud, leaf block exhaust outlet outlet in order to prevent, are located at water layer 40 on the valve body 2 of the present embodiment
Geotextiles sealing 1 is further sleeved with outside interior end.
In order to ensure that the position for being embedded with valve body 2 of antiseepage film 31 can still have good anti-seepage effect, in valve body 2
Antiseepage junctional membrane 5, antiseepage junctional membrane 5 and 31 lap hermetically of antiseepage film are connected on side wall.
For the ease of fixed antiseepage junctional membrane 5, to ensure that it is good that the overlap joint between antiseepage junctional membrane 5 and antiseepage film 31 has
Watertightly sealed effect, preferably on the side wall of valve body 2 be equipped with boss, one end of antiseepage junctional membrane 5 is fixed on boss, another
End is overlapped in antiseepage film 31, and fixed antiseepage junctional membrane 5 can effectively be overlapped with antiseepage film 31, good seepage-proof property.
In the present embodiment, the end on gas collection ponding layer 10 is equipped with pedestal 6, in order to which valve body 2 can be installed reliably
Between water layer 40 and gas collection ponding layer 10, and convenient for construction.
