Description
Technical field
The present invention relates to environmental improvement and water conservancy construction technical field that petrochemical industry, ore deposit are adopted contaminated sites such as smelting, solid waste disposal, especially relate to a kind of delta seal device that vertical flexible barrier system connects that is used for.
Background technology
People are increasingly high 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 the simple and easy yard of some rubbish, nonstandard refuse landfill have been polluted seepage.
The vertical barrier system is the quickest and safest method that flow of liquid is descended in shutoff nocuously, 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 need two films be fixed together and form complete barrier film wall, and linkage itself will keep the impermeability of self simultaneously, prevents to pollute to pollute diffusion by the linkage seepage.The sweat soldering that available technology adopting is conventional, 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 that vertical flexible barrier system connects that is used for, so that address the above problem.
In order to realize the foregoing invention purpose, the technical scheme that the present invention adopts is following:
A kind ofly be used for the delta seal device that vertical flexible barrier system connects; Comprise the expansion waterstop pad and be arranged at HDPE geomembrane both sides respectively and and said HDPE geomembrane between keep the eye-splice of sealing and hold button; Said eye-splice evagination; The said button indent of holding, the outline of the cross section of said eye-splice and the said interior profile that holds the cross section of button cooperatively interact, and said eye-splice is provided with groove; The said correspondence position that holds button also is provided with the groove of corresponding size; The said button that holds on said eye-splice on the every said HDPE geomembrane and the said HDPE geomembrane of another piece matches when forming sealing device, said groove in the said eye-splice and the said expansion waterstop pad cavity that is formed for installing the expansion waterstop pad between the said groove of buckling correspondence position that holds, and said expansion waterstop pad is filled in the said expansion waterstop pad cavity.
The cross section of said eye-splice is outer triangle, and the said cross section that holds button is interior triangle.
Said eye-splice front end and both sides are provided with three grooves; The said correspondence position that holds button also is provided with the groove of corresponding size; The said button that holds on said eye-splice on the every said HDPE geomembrane and the said HDPE geomembrane of another piece links closely mutually when forming sealing device, forms three expansion waterstop pad cavitys that are used to install said expansion waterstop pad at said eye-splice front end and both sides.
Said eye-splice and said both sides of holding the other sweat soldering of deduction of points at said HDPE geomembrane.
Said expansion waterstop pad is processed 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 said HDPE geomembrane skewer gone into said supporting tool; With the mode of vibration first said HDPE geomembrane directly is driven into the impervious layer of soil layer together with said supporting tool with said vibrating hammer, three said expansion waterstop pads placed the said eye-splice or the said button that holds of second said HDPE geomembrane; Again second said HDPE geomembrane skewer gone into another said supporting tool; Making second said eye-splice or said on the said HDPE geomembrane hold button aims at said on first said HDPE geomembrane and holds button or said eye-splice and make every said expansion waterstop pad aim at a said expansion waterstop pad cavity; With the mode of vibration second said HDPE geomembrane directly is driven into the impervious layer of soil layer together with said supporting tool with said vibrating hammer, the said eye-splice on adjacent like this two said HDPE geomembranes and said is held button and is linked closely mutually and form the said sealing device that comprises said expansion waterstop pad; When the said HDPE geomembrane of N piece is installed, by that analogy; Polylith HDPE geomembrane is tightly connected by said 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 a cross section structure sketch map of the present invention.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the present invention is solved, below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
A kind of delta seal device that vertical flexible barrier system connects that is used for as shown in Figure 1; Comprise expansion waterstop pad 6 and be arranged at HDPE geomembrane 1 both sides respectively and and said HDPE geomembrane 1 between keep sealing eye-splice 4 with hold button 5; Said eye-splice 4 and said both sides of holding button 5 difference sweat solderings at said HDPE geomembrane 1; Said eye-splice 4 evaginations; Said button 5 indents of holding, the outline of the cross section of said eye-splice 4 and the said interior profile that holds the cross section of button 5 mate each other, and the cross section of said eye-splice 4 is outer triangle; The said cross section that holds button 5 is interior triangle; Said eye-splice 4 front ends and both sides are provided with three grooves, and the said correspondence position that holds button 5 also is provided with the groove of corresponding size, and the said button 5 that holds on said eye-splice 4 on the every said HDPE geomembrane 1 and the said HDPE geomembrane 1 of another piece links closely mutually when forming sealing device; Form three expansion waterstop pad cavitys that are used to install said expansion waterstop pad 6 at said eye-splice 4 front ends and both sides, said expansion waterstop pad 6 is filled in the said expansion waterstop pad cavity.Said expansion waterstop pad 6 is processed by the material that can expand.
