Background technology
People are more and more higher along with rapid economic development, industrialization and quickening of urbanization process for the requirement of dwelling environment, but the MSW generation also sharply increases thereupon.But, at present because solid waste is stored up for a long time and seepage has been polluted in simple and easy stackings of some rubbish field, nonstandard refuse landfill.
The vertical barrier system is the quickest and safest method of the harmful underground liquid stream of shutoff, and the assurance of direct protection with long-term shutoff can be provided.But the connection between two of the HDPE geomembranes is extremely important, not only needs two films are fixed together to form complete barrier film wall, and linkage itself will keep the impermeability of self simultaneously, prevents from polluting polluting diffusion by the linkage seepage.The sweat soldering of available technology adopting routine, seam crossing changes poor-performing for bearing the film discontinuity that geological movement, surface settlement cause, and causes tearing of seam crossing easily.
Summary of the invention
The purpose of this invention is to provide a kind of delta seal device for the connection of vertical flexible barrier system, in order to address the above problem.
In order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of delta seal device for the connection of vertical flexible barrier system, comprise the expansion waterstop pad and be arranged at HDPE geomembrane both sides respectively and and described HDPE geomembrane between keep the eye-splice of sealing and hold button, described eye-splice evagination, the described button indent of holding, the outline of the cross section of described eye-splice and the described interior profile that holds the cross section of button cooperatively interact, described eye-splice is provided with groove, the described correspondence position that holds button also is provided with the groove of corresponding size, the described button that holds on described eye-splice on the every described HDPE geomembrane and the described HDPE geomembrane of another piece matches when forming sealing device, described groove in the described eye-splice and the described expansion waterstop pad cavity that is formed for installing the expansion waterstop pad between the described groove of buckling correspondence position that holds, described expansion waterstop pad is filled in the described expansion waterstop pad cavity.
The cross section of described eye-splice is outer triangle, and the described cross section that holds button is interior triangle.
Described eye-splice front end and both sides are provided with three grooves, the described correspondence position that holds button also is provided with the groove of corresponding size, the described button that holds on described eye-splice on the every described HDPE geomembrane and the described HDPE geomembrane of another piece links closely mutually when forming sealing device, forms three expansion waterstop pad cavitys that are used for installing described expansion waterstop pad at described eye-splice front end and both sides.
Described eye-splice and the described both sides of other sweat soldering at described HDPE geomembrane of deducting points of holding.
Described expansion waterstop pad is made by the material that can expand.
During delta seal device that the vertical flexible barrier system in the present invention is installed connects, earlier first described HDPE geomembrane skewer gone into described supporting tool, in the mode of vibration first described HDPE geomembrane directly is driven into the impervious layer of soil layer together with described supporting tool with described vibrating hammer, three described expansion waterstop pads placed described eye-splice or the described button that holds of second described HDPE geomembrane; Again second described HDPE geomembrane skewer gone into another described supporting tool, make second described eye-splice or described button that holds on the described HDPE geomembrane aim at described on first described HDPE geomembrane and hold button or described eye-splice and make every described expansion waterstop pad aim at a described expansion waterstop pad cavity, in the mode of vibration second described HDPE geomembrane directly is driven into the impervious layer of soil layer together with described supporting tool with described vibrating hammer, the described eye-splice on adjacent like this two described HDPE geomembranes and the described button that holds link closely mutually and form the described sealing device that comprises described expansion waterstop pad; When the described HDPE geomembrane of N piece is installed, by that analogy; Polylith HDPE geomembrane is tightly connected by described sealing device and forms vertical flexible barrier film wall.
Compared with prior art, the invention has the advantages that:
1. the present invention has extremely strong anti-steady chemical property, the corrosion that can resist pollutant, long service life.
2. the present invention can make the face body of wall on both sides have fabulous extension at break performance, can resist foundation settlement, slight earth's crust displacement etc.
3. three of the expansion waterstop pad grades of sealings can be guaranteed the lasting sealing of vertical flexible barrier film wall junction among the present invention.
Description of drawings
Fig. 1 is cross section structure schematic diagram of the present invention.
