Interface Anti-seeping technology.
As an improvement, the section of the rubber seal is i shaped cross section, the both wings edge of i shaped cross section is located at
Inside and outside HDPE plastic drainpipe, two sections of HDPE plastic drainpipe external concaves are located just at positioned at the I-shaped edge of a wing in outside
In slot.
As an improvement, when cutting flat with processing, the notch of two HDPE plastic drainpipes is respectively positioned on exterior groove in step 3
Middle when the splicing of such two HDPE plastic drainpipes, or in interface forms a complete annular groove.
As an improvement, the exterior flange shape of the rubber seal is matched with groove section shape, so that rubber seal
After enclosing water-swellable, just in the groove full of two HDPE plastic drainpipe stitching portions.
As an improvement, the interior flange shape of the rubber seal is to be close to the plate of HDPE plastic draining inside pipe wall
Shape.
As an improvement, the HDPE plastic drainpipe is HDPE binary wall twisting and pipe or HDPE double-wall corrugated pipe.
As an improvement, the Hot melt adhesive tape is the Hot melt adhesive tape of included heating wire, when hot-melt adhesive paste, heating wire is led to
Electricity, until adhesive tape links together two HDPE plastic drainpipe meltings.
The medicine have the advantages that
(1) the connector construction method of HDPE plastic drainpipe of the present invention uses the connection type of hot-melt adhesive paste, is connecting
Mouth is filled using water swelling rubber ring, to avoid the occurrence of leakage phenomenon during making HDPE pipe connection construction as far as possible.
(2) then HDPE plastic drainpipe is used at connection using processing is cut with bore interface between two sections of tubing
Water swelling rubber ring, which engages and carries out Hot melt adhesive tape, to be fixed, and is not needed to be flared, is made the company of HDPE plastic drainpipe in this way
Termination process is more easier to operate, and saves the construction time and also saves labour.
(3) HDPE plastic drainpipe makes two HDPE plastic drainpipe close adhesions to be docked after carrying out hot-melt adhesive paste,
Water swelling rubber ring fixed engaging wherein, the rubber ring water-swellable after water flowing is complete by gap filling at nozzle, improves
The docking intensity and durability of HDPE plastic drainpipe.
(4) water swelling rubber ring water-swellable 50%, after tubing water flowing, even if partial region is not fully sealed, rubber
Cushion rubber can also fill gap in pipe after being expanded, and not will cause assembled good HDPE plastic drainpipe, there are still part leak source hardly possiblies
The phenomenon that fill up.
