Abstract
The utility model discloses a combined type cable sheathing pipe has plastics inner tube and glass steel outer tube, is equipped with quartzy sand bed between plastics inner tube and glass steel outer tube, be equipped with the inlayer thread groove on the lateral wall of this plastics inner tube, be formed with orbit and the corresponding outer thread groove of inlayer thread groove on the inside wall of glass steel outer tube, the medial surface of quartzy sand bed matees with the lateral wall of plastics inner tube combines closely, and the lateral surface of quartzy sand bed matees with the inside wall of glass steel outer tube combines closely. This novel combined type cable sheathing pipe has promoted the joint strength between plastics inner tube and the glass steel outer tube greatly, and is firm reliable, the body layering problem that ftractures easily inside and outside avoiding to the practicality and the life of cable sheathing pipe have been promoted.
Description
Technical field
This utility model relates to glass fibre reinforced plastics technology field, specifically refers to a kind of Combined cable protecting pipe.
Background technology
Cable, in buried-pipe laying process, all needs to set protection pipe at cable jacket, to play protection cable effect.Have the composite cable conduit formed that thermosetting plastics (fiberglass) and thermoplastic pipes is nested together at present, also have and thermosetting plastics (fiberglass) and thermoplastic pipes are passed through intermediate adhesive layer, the composite cable conduit it being indirectly bonded together into.But, due to body difference in shrinkage inside and outside multiple tube, owing to cementability is not good, after placing a period of time, there will be cracking lamination problem.
Utility model content
The purpose of this utility model is in that the Combined cable protecting pipe providing a kind of inside and outside body integrally to combine closely to overcome bodies splittable lamination problem.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of Combined cable protecting pipe, has plastic inner pipe and fiberglass outer tube, is provided with quartz sand layer between plastic inner pipe and fiberglass outer tube；The lateral wall of this plastic inner pipe is provided with internal layer thread groove, and the medial wall of fiberglass outer tube is formed the outer layer thread groove that track is corresponding with internal layer thread groove；The medial surface of quartz sand layer mates with the lateral wall of plastic inner pipe combines closely, and the lateral surface of quartz sand layer mates with the medial wall of fiberglass outer tube combines closely.
Described fiberglass outer tube has the chlorine oxygen magnesium gelatinuous layer, glass fabric lining and the glass fiber compound material layer that set gradually from the inside to the outside.
The groove depth of described internal layer thread groove is more than the groove depth of outer layer thread groove.
The groove depth of described outer layer thread groove is not more than 1/3rd of the thickness of fiberglass outer tube.
Described plastic inner pipe is the one in pvc pipe, PE pipe, MPP pipe.
The lateral wall of described fiberglass outer tube is coated with polyethylene coating.
After adopting such scheme, this novel combined cable sheath tube, closely bonded by quartz sand layer between plastic inner pipe and fiberglass outer tube, this three is bonding between any two is configured to two-layer equation thread groove structure, and the track of ectonexine thread groove is corresponding, it is greatly improved the bonding strength between plastic inner pipe and fiberglass outer tube in this, solid and reliable, inside and outside body is avoided easily to ftracture lamination problem, thus improving practicality and the service life of cable sheath tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of this novel combined cable sheath tube.
Label declaration
Plastic inner pipe 1 internal layer thread groove 11
Fiberglass outer tube 2 outer layer thread groove 21
Quartz sand layer 3 polyethylene coating 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of Combined cable protecting pipe, as it is shown in figure 1, have plastic inner pipe 1 and fiberglass outer tube 2.Plastic inner pipe 1 is thermoplastic pipes, is specifically as follows the one in pvc pipe, PE pipe, MPP pipe.
This novel main innovation point is in that, is provided with quartz sand layer 3 between plastic inner pipe 1 and fiberglass outer tube 2.The lateral wall of plastic inner pipe 1 is provided with internal layer thread groove 11, and the medial wall of fiberglass outer tube 2 is formed the outer layer thread groove 21 that track is corresponding with internal layer thread groove 11.The corresponding pitch referring to the two of track is equal herein and the upper and lower corresponding setting of thread.The inside and outside side of quartz sand layer 3 is in thread face configuration suitable with internal layer thread groove 11, outer layer thread groove 21 respectively, the medial surface of quartz sand layer 3 mates with the lateral wall of plastic inner pipe 1 combines closely, and the lateral surface of quartz sand layer 3 mates with the medial wall of fiberglass outer tube 2 combines closely.
This novel combined cable sheath tube, closely bonded by quartz sand layer 3 between plastic inner pipe 1 and fiberglass outer tube 2, this three is bonding between any two all adopts thread groove form, and the track of ectonexine thread groove is corresponding, the body of both sides can be done the bonding of consistent high intensity by quartz sand layer 3, concordance is brought by the inside and outside form all adopting thread groove, high intensity is realized by quartz sand layer 3 matching thread groove structure, bonding strength between this plastic inner pipe 1 and fiberglass outer tube 2 is greatly improved, structure is very solid and reliable, avoid inside and outside body easily to ftracture lamination problem, also extend service life.
Further, the groove depth of internal layer thread groove 11 is more than the groove depth of outer layer thread groove 21, and the groove depth of outer layer thread groove 21 is not more than 1/3rd of fiberglass outer tube 2 thickness.Particular preferred embodiment, the groove depth of internal layer thread groove 11 is 1.5-2 times of the groove depth of outer layer thread groove 21.By the groove depth of internal layer thread groove 11 groove depth more than outer layer thread groove 2, namely such fiberglass outer tube 2 keeps the same mode with internal layer to mate being connected, strengthen switching performance, and fiberglass outer tube 2 still can keep the uniformity that thickness is relative, namely the relative uniformity of whole protecting pipe intensity is kept, this intensity ensureing whole protecting pipe and service life.
Preferably, the structure of fiberglass outer tube 2 is, has the chlorine oxygen magnesium gelatinuous layer, glass fabric lining and the glass fiber compound material layer that set gradually from the inside to the outside.It is also preferred that the left the consistent helicitic texture that all adopts between any two of this three layers is closely integrated.Fiberglass outer tube 2 is provided with this intermediate layer of glass fabric lining, thread groove form is preferably all adopted to be combined between this intermediate layer with adjacent two layers, by this structural design, make fiberglass outer tube 2 can be able to consolidate with plastic inner pipe 1 further and reliable high-strength integrated compound.
Preferably, the lateral wall of fiberglass outer tube 2 is also coated with polyethylene coating 4, is used for fiberglass outer tube 2 is made protective action, it is to avoid it is scraped off etc. to cause and breaks and affect intensity and service life.
The foregoing is only this novel preferred embodiment, all equalizations done with this novel right change and modify, and all should belong to this novel scope of the claims.
