Description
Technical field:
The present invention relates to a kind of prefabricated direct-buried thermal insulation pipe road hot melt and bury thread repaired mouth panel assembly and a preparation method.
Background technology:
At present, original repaired mouth plate welding is the most additional electric heating melting after repaired mouth coiled sheet bag, and bundle is seen on surface
Fastening solid, sweat soldering reaches one, but owing to the outer pillar temperature of pipeline is low, does not reaches thermo-fuse, it is impossible to molten
Changing, simply repaired mouth plate is pasted onto outer pillar surface after dissolving, and causes outer pillar and repaired mouth plate to realize one never, and infiltration is existing
As generally.Along with utilidor substantial amounts of application at home, need to construct at the scene in the coupling part of pipe joint part, by
Urgent in the engineering time, the reason such as natural temperature cooling, cause pipeline after steel-pipe welding, the outer pillar sweat soldering matter of insulating tube
Amount cannot promote, and causes heat insulation effect at pipe joint low, and the infiltration of outer pillar not prison welding is the master causing pipe temperature to decline
Wanting reason, along with the variation of temperature, the extruding of soil, the position being pasted not strongly arises that gap and ruptures, soil moisture
Immediately enter in heat-insulation layer, cause heat insulation effect to decline to a great extent.
Summary of the invention:
It is an object of the invention to provide a kind of prefabricated direct-buried thermal insulation pipe road hot melt and bury thread thermofusion device of repaired mouth plate and a making
Method, the problem solving the outer pillar not prison welding of utilidor.
Above-mentioned purpose is realized by following technical scheme:
A kind of prefabricated direct-buried thermal insulation pipe road hot melt buries a repaired mouth panel assembly, and its composition includes: repaired mouth plate, described repaired mouth plate
Inside being placed with one group of heater strip, described repaired mouth plate has 2 foam holes, described heater strip is connected with electrical terminals, described
Electrical terminals is connected with power supply.
Described prefabricated direct-buried thermal insulation pipe road hot melt buries a repaired mouth panel assembly, and the material of described repaired mouth plate is polyethylene
Plate, the outer perimeter of a length of different size insulating tube, width is fixed dimension.
Described prefabricated direct-buried thermal insulation pipe road hot melt buries a repaired mouth panel assembly, the repaired mouth plate that described heater strip is nuzzled described
Interior 1mm is deep, and described electrical terminals is on the position that described repaired mouth plate one end is symmetrical.
Described prefabricated direct-buried thermal insulation pipe road hot melt buries a repaired mouth panel assembly, and 2 described foam holes are at described repaired mouth
On plate away from side distance border width in the symmetric position of 10-50cm.
A kind of prefabricated direct-buried thermal insulation pipe road hot melt buries a preparation method for repaired mouth panel assembly, when constructing at the scene, by repaired mouth
The roll that plate has hot melt to bury silk wraps in outside the outer pillar termination of 2 insulating tubes, is close to pillar outside both sides, apart from outer pillar limit
Edge distance keeps uniformly, makes the outer pillar of pipeline closely be affixed with repaired mouth plate by fixing device, and centre is exactly pre-buried thermo-fuse,
Then being connected with the mains by electrical terminals, electric current passes through thermo-fuse, makes the polyethylene fusing that thermo-fuse will closely be affixed so that pipe
Outside road, pillar is consequently flowed together with repaired mouth plate, forms one, i.e. forms seamless outer pillar and connect after cooling, soil moisture
The heat-insulation layer in pipe cannot be penetrated into, thus serve high-efficiency insulated function, be fixed with the outer pillar spacing of different size pipeline
A size of width, is fixed the length of size with different size insulating tube outer perimeter, forms rectangle, according to outer pillar thickness is
The high density polyethylene (HDPE) plate of standard, on the side that polyethylene board is the longest, at distance border width in the position of 10-25cm,
Use hot melt to bury a machine, by the most molten for the thermo-fuse degree of depth being embedded in polyethylene board 1mm, connection hot melt is set in symmetrical one end
The electrical terminals of silk.
Beneficial effect:
1. the present invention can improve the outer pillar welding quality of utilidor, stops soil moisture and penetrates into heat-insulation layer, causes steel pipe
Interior hot water heat is scattered and disappeared by the heat-insulation layer of infiltration, causes heating network overall thermal efficiency to decline to a great extent, for ensureing heat supply temperature
Degree, increases energy resource consumption, causes the waste energy, the problem that air pollution is serious.
Prefabricated direct-buried thermal insulation pipe road of the present invention hot melt buries a repaired mouth plate can make outer pillar cross cut end (of a beam) obtain with repaired mouth plate
Uniform hot melt, thus be integrally forming after cooling, completely cut off the problem that soil moisture is penetrated into heat-insulation layer, it is achieved that site operation
Heat insulation effect is consistent with precognition heat insulation and preservation effect.
Due to the fact that and imbed thermo-fuse in advance, repaired mouth plate is after volume bag, and thermo-fuse is in the face of the outer pillar of insulating tube, through tying up
Tightly being affixed outer pillar, after connecing electricity, thermo-fuse melts outer pillar and repaired mouth plate simultaneously, and the polyethylene after synchronizing fusing is blended in
Together, form seamless integrated polyethylene and connect, temperature and the change of soil, the polyethylene of one all will not be made to form phase
Variation from, thus realize national standard require high-quality repaired mouth heat insulation effect.
