Detailed Description
The present invention will be described in further detail with reference to examples in order to make the objects and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1-4, the embodiment of the invention provides a unidirectional drainage exhaust valve for hydraulic civil engineering, which comprises an upper hemisphere 3, a lower hemisphere 4, a rubber tube 1 and a protective cover 2; the upper hemisphere 3 and the lower hemisphere 4 are connected through a bolt 5, the rubber tube 1 is pulled out from a water outlet pipe 6 at the top end of the upper hemisphere 3, and a protective cover 2 is arranged at the top end of the upper hemisphere 3; the rubber tube 1 is pulled out from the protective cover 2, and one end of the rubber tube is clamped in the water outlet tube 6 at the top end of the upper hemisphere 3. The lower hemisphere 4 is uniformly provided with water and air discharge holes, and geotechnical cloth is filled in the upper hemisphere 3 and the lower hemisphere 4. The upper hemisphere 3 and the lower hemisphere 4 comprise hemispheres and outer rings arranged at the outer edges of the opening ends of the hemispheres, and the two outer rings are provided with matched bolt holes. The center of the lower hemisphere 4 is provided with a positioning needle 7, the tail end of the positioning needle is fixedly connected with the center of the inner bottom surface of the lower hemisphere 4, and the other end of the positioning needle extends into the upper hemisphere 3.
The embodiment of the invention also provides a method for arranging the hydraulic and civil engineering unidirectional drainage exhaust valve, which comprises the following steps:
s1, before building and paving a geomembrane at the bottom of a reservoir, fixing a lower hemisphere on the middle surface of a sand layer at the bottom of the reservoir, and wrapping a layer of geotextile on the outer side of the lower hemisphere to prevent sand particles from blocking a water inlet hole;
s2, building and paving a geomembrane at the bottom of a reservoir, and enabling a positioning needle at the center of a lower hemisphere to penetrate through the geomembrane so as to be helpful for positioning when an upper hemisphere is installed;
s3, finding the installation position of the lower hemisphere, and cutting off the corresponding geomembrane above the lower hemisphere;
s4, pulling the rubber tube out of the inner side of the upper hemisphere, and clamping the rubber tube at a water outlet of the upper hemisphere;
s5, the geotextile is stuffed in the upper hemisphere and the lower hemisphere, then the geotextile is aligned with bolt holes on the upper hemisphere and the lower hemisphere, and the upper hemisphere and the lower hemisphere are fixed by bolts; and (5) finishing the installation.
The method comprises the steps of fixing the lower hemisphere below the geomembrane at the bottom of a reservoir, cutting off the geomembrane right above the lower hemisphere, and allowing water and gas in the sand layer at the bottom of the reservoir to enter from the water and gas drainage port on the surface of the spherical shell of the lower hemisphere. Geotextile is filled in the two hemispheres to serve as a reverse filtering material, the two hemispheres are fixed by bolts, and the rubber tube is pulled out from the water outlet pipe of the upper hemispheres. Thus, the water and gas at the bottom of the reservoir enter the ball from the lower hemispherical hole, and after being reversely filtered by geotechnical cloth in the ball, the water and gas prop up the rubber tube along with the increase of water pressure, so that the rubber tube flows into the warehouse. When the water content at the bottom of the warehouse is less, the water content entering the ball is also less, the water pressure is smaller, and the rubber tube cannot be opened, so that the water in the warehouse is effectively prevented from flowing backwards.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
