Abstract
The utility model discloses an external glass fiber reinforced plastic directly-buried thermal-insulating pipeline and an external polyethylene directly-buried thermal-insulating pipeline, in particular to a waterproof sealed opening butt-jointed with glass fibre reinforced plastics pipeline and polyethylene pipeline, which comprises an external glass fiber reinforced plastic pipeline and an external polyethylene pipeline butt-jointed each other and is characterized in that: the periphery of the joint of the external glass fiber reinforced plastic pipeline and the external polyethylene pipeline is provided with a prefabricated sleeve; both sides of the joint and the inside of the prefabricated sleeve are provided in turn with a baffle ring, an inner seal ring, a glass fiber reinforced plastic reinforcing layer and an outer sealing piece from inside to outside; the external surface of the external polyethylene pipeline is provided with a modified layer made of bitumen mastic adhesive tape. The prefabricated raglan sleeve and inside and outside sealing waterproof design of the utility model guarantees directly-buried laying under poor environmental condition through preventing on-site man-made uncertainties.
Description
(1) technical field under
The utility model relates to the external glass fibre reinforced plastics direct-buried insulated pipe and polyethylene protects direct-buried insulated pipe outward, the waterproof sealing repaired mouth that particularly a kind of fiber reinforced plastic pipe is docked with polyethylene pipe.
(2) background technique
Current, pillar outside buried pipelines such as direct-burried heat supply pipeline and oil transportation adopt Glass Steel Tube and polyethylene pipe conduct more and more.In actual applications, because the concrete asynchronism(-nization) of implementing of design proposal difference or project tends to needing to occur external glass fibre reinforced plastics direct-buried insulated pipe and polyethylene to protect the situation that direct-buried insulated pipe is incorporated into the power networks outward.But traditional on-the-spot repaired mouth mode often adopts the on-the-spot processing mode of manual pasting, and the assurance of quality depends on operator's experience and sense of responsibility, and personal factor is too many; In addition, two kinds of outer pillars that repaired mouth relates to are because of the material difference, and ability of temperature distortion is also different separately for they; Therefore quality problems such as infiltration, cracking often appear.For buried pipeline, the quality of repaired mouth will directly influence the life-span of pipe network and the Security of normal operation.In view of this, my company has researched and developed the waterproof sealing repaired mouth that fiber reinforced plastic pipe is docked with polyethylene pipe on the basis of external glass fibre reinforced plastics pipe waterproof sealing repaired mouth.
(3) summary of the invention
At the deficiency of current techniques, the waterproof sealing repaired mouth that the utility model provides a kind of reliable fiber reinforced plastic pipe to dock with polyethylene pipe.This waterproof sealing repaired mouth not only can solve on-the-spot hand and stick with paste the difficult problem of personal factor control that technology is brought; and the influence of adverse environment conditions such as phreatic high to the pipe network general safety stopped in triple protection design reliably; simultaneously, solved reliable the dock problem of fiber reinforced plastic pipe with polyethylene pipe.
The utility model is achieved by the following scheme:
The waterproof sealing repaired mouth that a kind of fiber reinforced plastic pipe is docked with polyethylene pipe comprises the outer pillar of the external glass fibre reinforced plastics pipe of mutual butt joint and polyethylene, and its special way is: the outer periphery, pillar joint of described external glass fibre reinforced plastics pipe and polyethylene is provided with prefabricated oversleeve; Be provided with baffle ring, inner seal ring, glass fibre reinforced plastics enhancement layer, outside seal may in both sides, joint, the prefabricated oversleeve from inside to outside respectively successively.
Fiber reinforced plastic pipe waterproof sealing repaired mouth of the present utility model is foaming layer between outer pillar joint of described external glass fibre reinforced plastics pipe and polyethylene and the prefabricated oversleeve.
For further enhanced leaktightness, the two ends of described prefabricated oversleeve are provided with a ramp type fw frp reinforced layer.
It is the modified layer of material that the outer pillar outer surface of described polyethylene is provided with the pitch sealing tape.
There are following characteristics in the utility model:
The one, the prefabrication oversleeve has been stopped the unsafe factor influence that on-the-spot abominable operating conditions is brought.The prefabrication oversleeve that this product adopts is produced by production standard and technology that straight tube protects Glass Steel Tube outward, and the detection of its quality of product and requirement are by heat preservation pipe prefabricated execution.Corresponding supporting seal element all is prefabricated in the factory, as baffle ring etc.Can stop the on-the-spot adverse effect that does not possess operating conditions and bring like this.Traditionally, the work on the spot amount is big, and can't quality monitoring.
The 2nd, inside and outside waterproof sealing design.
For directly buried pipeline, abominable underground environment condition will directly restrict the life-span and the safety of pipeline.Especially groundwater level region, tratitional technology is difficult to ensure to this.The utility model design has been adopted in the both sides of repaired mouth section and has respectively been added inside and outside twice waterproof sealing, immerses thermal insulation pipe to prevent underground water, causes the whole destruction of pipe network.
The 3rd, adopt the on-the-spot winding layer of strengthening as last pipe protection, prefabricated oversleeve and straight tube are done as a whole the reinforcement.Gentle slope transition design is adopted in prefabricated oversleeve and straight tube joint.
The 4th, repaired mouth is set up the modified pitch sealing tape on the pillar outside polyethylene.This material and polyethylene pipe have good bond strength, and its thermal expansion coefficient and glass fibre reinforced plastic material are more approaching simultaneously.This modified measures can be eliminated the difference of polyethylene and glass fibre reinforced plastics expanded by heating ability, makes repaired mouth more safe and reliable under rugged environment.
Reliable effect of the present utility model is: the design of triple protection is reduced to work on the spot minimum, and the operation of controlled quality is put into factory and carries out prefabricated, detection.Compare with traditional product, the guarantee of prefabricated oversleeve and inside and outside water-tight reliable design the directly buried installation under the severe environmental conditions.Stopped on-the-spot artificial unreliable factor, its Security and manufacturability can finely guarantee.The modified measures of repaired mouth can be eliminated the difference of polyethylene and glass fibre reinforced plastics expanded by heating ability, makes repaired mouth more safe and reliable under rugged environment.
