Description
Technical field
The utility model category is related to a kind of HDPE hollow walls riffled tube in pipe technology field.
Background technology
In urban construction, the embedded of subsoil drain and blow-off pipe is important municipal works, existing pressure pipeline
Polythene material generally is, because the compressive resistance of polyethylene is poor, if to reach certain anti-pressure ability, extra strong pipe
Wall, or add steel band in tube wall, so greatly increase the weight of body, production cost also increases, therefore, it is necessary to provide one
The novel belt material of outer ripple plastic winding structure wall pipe of the kind with hollow reinforced rib, to overcome lacking on said structure
Fall into.
The content of the invention
The purpose of the present utility model is overcome the deficiencies in the prior art, there is provided a kind of winding pipe pressure pipeline.
Composite strip is made with superhigh molecular weight polyethylene material, the HDPE hollow wall riffled tubes for having winding pipe outside body.
The present utility model is achieved through the following technical solutions：
A kind of HDPE hollow walls riffled tube, the tubing formed by the composite strip spiral winding welding with reinforcement, its
It is characterised by：The composite strip with reinforcement is provided with hollow boss reinforcement, and there is symmetrical welding composite strip both sides
Faying face is molded, wrapping machine is helically wound composite strip and fuses into tubing body in faying face overlap joint melten gel, manages
Material inner body wall is cylindrical wall, tubing body outer wall is that spiral surrounding is horizontal in hollow boss reinforcement thereon, reinforcement
Rectangular cross-section structure, there are rectangular through holes among reinforcement, reinforcement side is fusion face, and reinforcement both upper ends thereof is provided with arc
Shape is raised, and HDPE high density polyethylene (HDPE)s or FRPP polypropylene and steel band are mixed and made into half by the composite strip of reinforcement by extruder
Finished product, wrapping machine are helically wound the composite strip of reinforcement and fuse into tubing body through melten gel at fusion face,
Tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding in hollow boss reinforcement thereon, hollow convex
Play reinforcement to play a supporting role, improve the ring stiffness of whole pipeline, the crushing resistance of pipeline is also correspondingly improved；Described
The composite strip of reinforcement is combined by 1 or 2 piece of tape, and 2 piece of tape can be connected by fusion face.
The present utility model has the characteristics that good ring stiffness and face of weld heat seal strength are high.
Brief description of the drawings
Fig. 1 is the reinforcement composite strip sectional view of HDPE hollow wall riffled tubes.
Fig. 2 is the composite strip sectional view of 2 reinforcements.
In figure：Rectangular through holes 1, fusion face 2, arc convex 3 and welding faying face 4.
Embodiment
Content of the present utility model is described further below in conjunction with the accompanying drawings：
It as shown is the reinforcement composite strip sectional view of HDPE hollow wall riffled tubes, including rectangular through holes 1, fusion
Face 2, arc convex 3 and welding faying face 4.
The tubing that HDPE hollow walls riffled tube is formed by composite strip spiral winding welding, composite strip is by extruder by PE
Material and PP bellowss are mixed, and PP bellowss form hollow reinforced rib, and composite strip both sides have symmetrical fusion molding to combine
Face, PE material are first extruded by an extruder pipe liner is coiled on wrapping machine, then PE material and PP ripples are extruded by another extruder
Line multiple tube sticks the heat on internal lining pipe and is entwined, and wrapping machine is helically wound composite strip and overlapped in faying face molten
Glue fuses into tubing body, and it is hollow thereon that tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding
Protruding reinforcing rib, hollow reinforced rib is perpendicular to tube wall.
Claims (2)
1. a kind of HDPE hollow walls riffled tube, the tubing formed by the composite strip spiral winding welding with reinforcement, it is special
Sign is：The composite strip with reinforcement is provided with hollow boss reinforcement, and composite strip both sides, which have, to be symmetrically fused into
Type faying face, wrapping machine are helically wound composite strip and fuse into tubing body, tubing in faying face overlap joint melten gel
Inner body wall is cylindrical wall, tubing body outer wall is that spiral surrounding is transversal in hollow boss reinforcement thereon, reinforcement
Face is rectangular configuration, there is rectangular through holes among reinforcement, and reinforcement side is fusion face, and reinforcement both upper ends thereof is provided with arc
Projection, wrapping machine are helically wound the composite strip of reinforcement and fuse into tubing body through melten gel at fusion face.
2. HDPE hollow walls riffled tube according to claim 1, it is characterised in that：The composite strip of described reinforcement by
1 or 2 piece of tape are combined, and 2 piece of tape can be connected by fusion face.
