Abstract
The utility model discloses a High-Density Polyethylene (HDPE) reinforced traction pipe, which comprises helically wound hollow pipes and a pipe wall formed by sols for adhering the adjacent hollow pipes, wherein the both ends of the HDPE reinforced traction pipe are respectively welded with a socket and a bell mouth; a ring of electric heating elements are disposed on the outer wall of the socket; the both ends of the electric heating elements are located at one end, which is welded with the pipe wall, of the socket; and thermal welding is realized by electrifying the both ends of the exposed electric heating element. The HDPE reinforced traction pipe employs the hollow wall winding technology; the hollow wall wound traction pipe has excellent flexibility and overall outer pressure resisting ability, thus ensuring traffic safety on overloaded roads; in addition, socket and bell moth type electric welding connection leads connection to be quick and operation to be convenient in construction, saves labor power as well as machines and tools, and also is high in connection quality and one hundred per cent leakage-free.
Description
Technical field
The utility model relates to the tubing technology, and particularly a kind of HDPE strengthens traction tube.
Background technique
Traction tube be exactly a kind of can railroad crossing, the pipeline of highway, generally installing cement sleeve pipe or Steel Sleeve under roadbed, traction tube draw from sleeve pipe in the past, with the safety of assurance pipeline and railway, highway.The good toughness of traction tube, cementability is very good, can guarantee the smooth laying of pipework.
The one side that belongs to trenchless technology; Trenchless technology is meant through means such as guiding, directional drillings; Under the situation of the minimum part excavation in the face of land, (refer generally to entrance and exit small size excavation); Therefore lay, change and repair the construction technique of various underground utility, surface drying is disturbed for a short time over the ground, has higher social economic effect.Mainly comprise technological methods such as horizontal orientation creeps into, push pipe, miniature tunnel, booster, impact.This technology comes from the seventies in 20th century, and imports China into the nineties, is widely used at present feeding water, the new pipe-line construction and the old pipeline rehabilitation in field such as draining, electric power, communication, combustion gas; Also can be applied to the aspects such as protection of historical relic, heritage building, along with the increase of present road traffic flow, significantly lifting or the like of carrying capacity; Taking place frequently of geological movement; The ability that the pliability of existing traction tube and whole critical external compressive resistance ability, corrosion-resistant and chemically resistant material corrode is enough not good, and the rubber ring class joint that is adopted is in construction; Quality of connection; Joint is strong, guarantees the uniformity of interface material, structure and body itself, and the aspect can not effectively satisfy existing needs.
Summary of the invention
The purpose of the utility model to provide exactly a kind of tube wall bulk strength high, be difficult for breaking, non-leakage, reliable a kind of HDPE strengthens traction tube.
A kind of HDPE strengthens traction tube; Said traction tube comprises the tube wall that the melten gel of hollow tube that spiral twines and bonding adjacent hollow tube forms; There are socket and bellmouth in said HDPE enhancing traction tube two ends welding respectively; Said socket outer wall is provided with a circle electric heating element, and the two ends of electric heating element is positioned at weld one end of socket and said tube wall, switches on through the two ends of the electric heating element that exposes and realizes hot melt.
Said electric heating element is processed by the wire bending.
Described hollow tube is a square tube, and the outer corner angle of tube wall are circular arc.
Said hollow tube wall is thinner, and materials are less, and availability performance, quality higher H DPE raw material are processed, and both can reduce cost, and can guarantee the bonding fastness of melten gel and hollow tube again.
Compare with prior art, the advantage of the utility model is:
The traction tubing of hollow wall wrap style has good flexible and whole critical external compressive resistance ability, when under overweight load road surface is arranged, using, can guarantee current safety.
HDPE has the ability that extremely strong corrosion-resistant and chemically resistant material corrodes, and in that carry when laying in corrupt liquid or the soil in very corrosive need not any preservative treatment, performance is superior to other tubing greatly.
Pipeline adopts the molten interconnection technique of electric heating, quick construction, and quality of connection is high, and joint strength is big, guarantees the uniformity of interface material, structure and body itself, compares with rubber ring class joint or other mechanical splices, does not have the danger that causes leakage because of joint.
Description of drawings
Fig. 1 is the concrete structure of the utility model;
Fig. 2 is the concrete structure of the utility model socket.
Embodiment
Like Fig. 1-2 illustrated embodiment, a kind of HDPE strengthens traction tube, comprises the tube wall that the melten gel 2 of hollow tube 1 that spiral twines and bonding adjacent hollow tube forms.
HDPE enhancing traction tube both ends of the surface welding respectively have isodiametric bellmouth 4 and socket 3; On socket 3 outer surfaces, be provided with electric heating element 5; Said electric heating element 5 is processed by the wire bending; The two ends of electric heating element 5 is positioned at weld one end of socket 3 and hollow wall entwining tube; And two ends 6 energisings through the electric heating element 5 that exposes realize hot melt, and adjacent two pipes insert through socket 3 and reach socket joint in the bellmouths 4 and connect, and realize hot melt through the two ends of the electric heating element 5 that exposes is switched on then.
Imbed a circle electric heating element 5 at socket 3 ends.Electric heating element 5 is that first wire with brake forming is fixed on socket 3 outer wall intermediate portions; Wire two ends termination 6 is protruding and fixing perpendicular to socket 3, gives the wire two ends 6 energisings then, energising voltage 40A; Keep 10 minutes current"on"time; Socket 3 outer walls are contacted with electric heating element 5 and around the position high density polyethylene (HDPE) melt, thereby imbed socket 3 outer walls with about half of electric heating element 5, wire two ends 6 is imbedded in the outer wall of socket 3 near the connection position of pipe shaft one end.
When site construction, the socket 3 with a high density polyethylene (HDPE) enhancing hollow wall entwining tube is inserted in the bellmouth 4 of another root hollow wall entwining tube; Then through switching on perpendicular to the outwardly directed electric heating element 5 of bellows; Energising voltage 54A keeps 20 minutes current"on"time, make contact with electric heating element 5 and around the high density polyethylene (HDPE) thawing of bellmouth 4 inwalls and socket 3 outer surfaces; Link together thereby two socket joint jointing type high density polyethylene (HDPE)s are strengthened the hollow wall entwining tube, become as a whole.Socket joint through high density polyethylene (HDPE) being strengthened hollow wall entwining tube docking operation successively repeatedly so just can connect into long and pipeline that good seal performance is arranged.
