Specific embodiment
First embodiment
As shown in Figure 1 to Figure 2, construction now is laid with one layer of geomembrane 12 generally on the upside of sandy soil layer, sinks on the upside of geomembrane
Product has mud 13, has clear water layer 14 on the upside of mud.
The super standard flood antiseepage exhaust apparatus, including one layer of waterproof ventilated membrane 11, the waterproof ventilated membrane (breathing paper)
It is a kind of novel high polymer waterproof material.The technology of waterproof ventilated membrane is the introduction since American-European countries earliest, however state
The manufacture craft of interior product is multifarious, and the product quality of each producer is irregular, could not form a unified quality mark
It is quasi-.In fact, waterproof ventilated membrane mainly has three layers of composition: PP spun-bonded non-woven fabrics, PE gas permeable polymer film, PP spun-bonded non-woven fabrics.
The effect of spun-bonded non-woven fabrics mainly enhances pulling force and hydrostatic pressing and protection middle layer (ventilated membrane), really breathes freely in mainly leaning on
Interbed PE gas permeable polymer film.
The working principle of waterproof ventilated membrane: in the state of steam, particle water is very tiny, according to the original of capillary moving
Reason, can smoothly penetrate into capillary to the other side, so that vapour phenomenon occur.After moisture condensation becomes droplet, particle becomes
Greatly, due to the effect of droplet surface tension (mutual " pull and contend with " between hydrone), hydrone cannot smoothly be detached from droplet
The other side is penetrated into, that is, the infiltration of water is prevented to occur, steam film is made to have the function of waterproof.
The waterproof ventilated membrane is between geomembrane and sandy soil layer, is embedded in the middle part of the waterproof ventilated membrane soft ventilative
Pipe 21, the soft permeability cell are connected with air inlet hard tube 22, and the air inlet hard tube passes through waterproof ventilated membrane, geomembrane, mud
After be connected with a self-closing polymer tube band 23, the self-closing polymer tube band is open equipped with a tail end, for being discharged in geotechnique
Air on the downside of film.The self-closing polymer tube band touches water in tail end opening hypothesis, can will invade the moisture at this
Expansion is absorbed, to control the inflow once again of water.
Simultaneously when encountering high standard flood, which can be become flat by the impulse force of water, and tail end opening connects
It contacts water, has preferably carried out the closure of water.
The self-closing polymer tube band 23 can be made of absorption resin of sodium polyacrylate or high hydroscopic resin-SAP.
Second embodiment
The difference is that, it is equipped with a narrow necking 231 in the middle part of the self-closing polymer tube band with first embodiment,
It is easy to be bent when encountering high standard flood, at this, avoids the entrance of moisture.
3rd embodiment
A narrow necking 231 is equipped in the middle part of the self-closing polymer tube band 23, the narrow necking is by self-closing polymer tube
Band is divided into upper tube band 233 and down tube band 232, and upper detent rubber ring 236 and lower detent rubber ring are equipped in the middle part of the upper tube band
235, the upper detent rubber ring 236, lower detent rubber ring 235 and upper tube band inner wall form a spherical hollow space 237, in upper tube band
In be placed with a hollow rubber ball sealer 234, the hollow rubber ball sealer is on the downside of spherical hollow space.
Scheme optimization, the diameter of hollow rubber ball sealer are greater than the diameter of spherical hollow space.
If it is peacetime state, as shown in figure 5, hollow rubber ball sealer drives upper tube band to stretch out water under buoyancy
Face, with easy to exhaust.
When there is high standard flood, hollow rubber ball sealer is struck by water impact to spherical empty
It is intracavitary, so that hollow rubber ball sealer and spherical hollow space are interference fit, realize the sealing at this, while the tail end of upper tube band is opened
It is self-closing that water progress is met at mouthful.It is same to realize sealing.
Narrow necking at this time, which is also bent, realizes sealing at this.Triple seal effect, avoids recharge.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
