Property film, the HDPE double-wall corrugated pipes are equipped with the through-hole that is connected with slot on the outer wall at slot end.
By using above-mentioned technical proposal, storage calcium lime powder is coordinated by water-soluble film.In more HDPE double-walleds
After bellows links together in a manner that plug and slot are mutually inserted, the gap water filling to plug and slot is water-soluble
Property film be dissolved in water after the time of one end, at this time water directly and calcium lime powder contacts, generating a large amount of heat makes
The inner wall section fusing for obtaining the outer wall and slot of plug is joined together to form sealing surface.
The present invention is further arranged to：The outside of the plug is equipped with heat insulation support ring, the heat insulation support ring and plug
Between gluing, sealing.
By using above-mentioned technical proposal, heat insulation support ring is set in the outside of plug so that plug when heating
Part will not be melted and influence the shape of water transport channel in HDPE double-wall corrugated pipes.
The present invention is further arranged to：The bottom of the annular groove is equipped with endless metal circle.
By using above-mentioned technical proposal, setting endless metal circle causes the outer wall of slot direct to avoid concentrating heat release
It is worn by molten so that heat can be spread out by endless metal circle.
The present invention is further arranged to：The width of the endless metal circle is more than the width of annular groove, the endless metal
In the annular groove sidewall of both ends insertion of circle.
By using above-mentioned technical proposal, the width of setting endless metal circle increases axial side more than the width of annular groove
Upward fusing length so that fusing postcooling bonds the sealing area bigger to be formed, and plays better seal effect.
The present invention is further arranged to：The internal diameter of the slot is more than the outer diameter of heat insulation support ring, divides on the inside of the slot
The close to the first annular seal convexity of HDPE double-wall corrugated pipe ports and far from the double-wall corrugated pipe ports of HDPE is not formed
The minimum diameter of second ring seal convexity, the first annular seal convexity and the second ring packing protrusion is respectively less than heat insulation support
The outer diameter of ring, the through-hole and slot connectivity part are located between annular groove and the second ring packing protrusion.
It by using above-mentioned technical proposal, is carried out since water-soluble film dissolves needs a period of time in water, by the
Sealing is cooperatively formed between one ring packing protrusion and the second ring packing protrusion and the outer wall of heat insulation support ring so that by logical
The water that hole is injected between heat insulation support ring and slot will not be lost in, avoid the duration water filling in water-soluble film course of dissolution and
Lead to water resource waste.
The present invention is further arranged to：The outside of the heat insulation support ring is equipped with the face ring when being inserted into top to slot bottom
The water proof circle of shape slot medium position, the water proof circle abut sealing with water-soluble film.
By using above-mentioned technical proposal, it is only capable of flowing to water proof circle and first annular seal convexity by water proof circle water
Between position, position between water proof circle and the second ring packing protrusion is in dry state, in water proof circle and the second ring
Slot inner wall between shape seal convexity can smoothly link together when fusing with heat insulation support ring.
The present invention is further arranged to：It is there are four the through-hole is common and uniformly distributed in double-wall corrugated pipe circumferential direction, it is each described
The plug for sealing through-hole is equipped in through-hole.
By using above-mentioned technical proposal, four circumferentially uniformly distributed through-holes is set to facilitate water filling.By more HDPE double-walleds
Bellows coordinates grafting successively by respective plug and slot, later by positioned at HDPE double-wall corrugated pipes side one of them
Plug and the plug extraction positioned at highest point, pass through gap of the through-hole of side between water proof circle and first annular seal convexity
Middle water filling means to be already filled with water when having water spilling in the through-hole of upside.
The present invention is further arranged to：The axial line of the through-hole and the inner wall of slot are tangent.
By using above-mentioned technical proposal, the axial line of through-hole and the inner wall of slot is set tangent to cause HDPE double-walled waves
The location status that line pipe is put be not there are one through-hole just state upward when, as long as the both ends of through-hole have one end to be in higher
Position, it is possible to maintenance water level as high as possible so that calcium lime powder can come into full contact with water, will not be on the upside of upper end insert
The relatively low situation for being difficult to melt of slot inner wall temperature.
The present invention is further arranged to：The outer wall of the plug forms the zigzag protrusion of annular, and the plug is located at
One end outside through-hole forms ring-shaped handle.
By using above-mentioned technical proposal, in the outside of plug, setting zigzag protrusion enables plug and through-hole wall
Sealing is fitted closely, and ring-shaped handle can be then convenient for extracting plug.
In conclusion beneficial effects of the present invention are：
1st, water-soluble film is set to coordinate storage calcium lime powder.It is mutual by plug and slot in more HDPE double-wall corrugated pipes
After the mode of grafting links together, the gap water filling to plug and slot, water-soluble film is after the time of one end
It is dissolved in water, at this time water is directly contacted with calcium lime powder, is generated a large amount of heat and is caused the outer wall of plug and the inner wall of slot
Part fusing is joined together to form sealing surface；
2nd, it is cooperatively formed between the first annular seal convexity of setting and the second ring packing protrusion and the outer wall of heat insulation support ring close
Envelope so that the water injected between heat insulation support ring and slot by through-hole will not be lost in, and be avoided in water-soluble film course of dissolution
Middle duration water filling and lead to water resource waste.
