Description
Technical field
The invention belongs to the plumbing technical fields of municipal works no-dig technique pipeline, and in particular to a kind of fiberglass sand inclusion top
Pipe.
Background technology
Glass fiber reinforced steel push pipe with sand, other than the advantage with general jacking construction, as a kind of novel composite pipe, also
Have the characteristics that lightweight, high-strength, corrosion-resistant, long lifespan.The characteristics of especially corrosion-resistant, long lifespan, makes it receive much attention, glass
The application of steel push pipe with sand is more and more extensive.
In jacking construction, the connecting structure of connector be it is vital, in glass fiber reinforced steel push pipe with sand all at present
Using steel bushing ring joint type of attachment.This joint form meets that connection is oriented to, sealing, slip casting subtracts to a certain extent
The functions such as resistance and correction, but steel collar connection is used still to have the following defects：
1, it is rolled using steel plate due to steel collar, the accuracy of manufacture is not high, thus causes fit dimension error excessive, and installation is not
Just；
2, since the precision of fit dimension is relatively low, steel collar connection is only adapted to the sealing performance under low pressure, works as water pressure
Its barrier properties is difficult to ensure when higher.
3, it since steel collar has corrosion, is difficult to ensure using the Long-Term Properties of steel collar；
4, in existing glass fiber reinforced steel push pipe with sand definite-length-winding process, there is the cross winding layer axially enhanced, at both ends
Head inevitably becomes circumferential winding, and the axial strength for directly bearing the pipe end of top power is caused to weaken.
Invention content
Against the above deficiency, simple in structure, easy to connect, dependable performance have the purpose of the present invention is to provide a kind of
The glass fiber reinforced steel push pipe with sand of fiberglass connector sleeve ring function.
To achieve the goals above, the technical scheme is that：Glass steel clamp with fiberglass connector sleeve ring function
Sand push pipe, it includes tube body, and one end of tube body is socket end, and the other end is female end, it is characterised in that tube body 4, socket end 5,
Female end 3 is structure as a whole, and the outer diameter of socket end 5 is corresponding with the internal diameter of female end 3.
1-2 rubber groove 6 is provided in socket end 5, sealing rubber ring is corresponding with the number of rubber groove 6, sealing rubber ring
In rubber groove 6.
6 inside (being close to female end side) of rubber groove of socket end 5 is provided with slip casting drag reduction hole 7.
The port of the socket end 5, female end 3 is respectively equipped with guiding surface.
The present invention is structure as a whole using tube body 4, socket end 5, female end 3, in the outer diameter and 3 ground of female end of socket end 5
Diameter is corresponding.The prior art is equipped with steel collar, compared with prior art, the present invention having the characteristics that simple in structure；When construction only
It need to be by the socket end of a glass fiber reinforced steel push pipe with sand (hereinafter referred to as glass fiber reinforced steel push pipe with sand) with fiberglass connector sleeve ring function
It is inserted into and the female end of another glass fiber reinforced steel push pipe with sand can be realized between glass fiber reinforced steel push pipe with sand and glass fiber reinforced steel push pipe with sand
Connection, it is easy to connect；Since tube body 4 of the present invention, socket end 5, female end 3 are entwined on same wrapping machine, three has
Globality；And all using glass-reinforced plastic material, therefore compared with using steel collar, has the characteristics that dependable performance.
It is an advantage of the invention that：
1, glass fiber reinforced steel push pipe with sand is once-forming, is not required to steel collar, but has the function of that fiberglass connects lantern ring, and uses
Steel collar is compared, and 1/2 connecting portion is reduced；
2, the female end 3 of glass fiber reinforced steel push pipe with sand uses mold winding shaping, makes precision height, and connection mismatch error is small；
3, due to all being made of fiberglass, it can be ensured that 50 years or more Long-Term Properties；
