Higher to prefabricated profiled polyethylene cannula required precision, it is more polyethylene cannula specification kind to be present, the defects of poor universality.
Utility model content
The purpose of this utility model is to provide a kind of prefabricated direct-buried thermal insulation pipe repaired mouth electric heating melting cage plate, and it is prefabricated into out
Muzzle tubular construction, at laying construction scene, the split coupling structure is sleeved on connecing for two prefabricated direct-buried thermal insulation pipe outer jackets
Mouthful end, then by electric heating melting mode by pre-formed members ferrule openings both ends and pre-formed members sleeve pipe and two prefabricated direct-buried thermal insulation pipes
Outer jacket engagement, complete prefabricated direct-buried thermal insulation pipe outer jacket repaired mouth operation.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of prefabricated direct-buried thermal insulation pipe repaired mouth electric heating melting cage plate, it uses rectangle Hdpe as raw material,
The Hdpe one side arrangement heating wire net with, the heating wire net be fixed on rectangular plate a sides,
B while and fringe region during c, form the straight-flanked ring band that side opens, heating wire net with both ends be communicated with leading for power supply
Line；The pre-formed Hdpe is split coupling structure.
Above-mentioned prefabricated direct-buried thermal insulation pipe repaired mouth electric heating melting cage plate, in the Hdpe raw material another side
D sides both ends open up electric melting connection groove.
Above-mentioned prefabricated direct-buried thermal insulation pipe repaired mouth electric heating melting cage plate, the heating wire net in a manner of hot pressing with being fixed on square
Shape Hdpe a in, b and c sides fringe region.
The beneficial effects of the utility model are：
The utility model is in rectangle Hdpe raw material one side arrangement heating wire net with and by rectangle high density
Pre-formed polyethylene board raw material is split coupling structure, can be by opening sleeve at prefabricated direct-buried thermal insulation pipe laying construction scene
Pipe sleeve is mounted in two prefabricated direct-buried thermal insulation pipe joint areas, and split coupling one end and the groove position of the other end are pressed, then
Connect in a manner of electric heating melting at pre-formed members ferrule openings both ends and pre-formed members sleeve pipe with two prefabricated direct-buried thermal insulation pipe outer jackets
Close position and form hot-melting sealed band, complete prefabricated direct-buried thermal insulation pipe outer jacket repaired mouth operation.Because the utility model employs out
The sleeve structure of degree of lip-rounding formula, its dimension precision requirement is not only reduced, and available for shield outside the polyethylene cannula of different size
The repaired mouth operation of layer, there is the advantages of versatility is good, site operation facilitates.
