Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description.
As shown in fig. 3, fig. 4, fig. 5, fig. 6, a strenghthened type HDPE steel band reinforcing helical bellows structure, including bellows inside lining 1, helical steel band 2 and first filling layer 3, helical steel band 2 is the heliciform winding and is on the bellows inside lining 1 surface to be located between bellows inside lining 1 and the first filling layer 3 surface between helical steel band 2 is equipped with a plurality of strengthening ribs 4 that parallel, strengthening rib 4 is the heliciform winding on first filling layer 3 between helical steel band 2, strengthening rib 4 is equipped with second filling layer 5 outward, second filling layer 5 covers strengthening rib 4 and first filling layer 3 completely.
The reinforcing ribs 4 overlap with projections of both side edges of the spiral steel strip 2 in the vertical direction, but are separated from direct contact by the first coating layer 3. Gaps are left among the reinforcing ribs 4, and the gaps are filled and covered by a second filling layer 5. HDPE steel band reinforcing helical bellows's toughness mainly comes from the HDPE material, meet the installation condition or the partial ground settlement scheduling problem that have certain bend during pipeline construction inevitable, then need tubular product to have better toughness this moment, in order to reduce the life of local stress influence tubular product, the primary function of above-mentioned structure just lies in making under the condition that position intensity obtained obvious promotion between HDPE steel band reinforcing helical bellows's the ripple, still can guarantee that HDPE steel band reinforcing helical bellows has good toughness, in order to realize the installation of pipeline under the more adverse circumstances even in the bend environment, and can guarantee normal working life.
The reinforcing ribs 4 are flat steel belts, the material of the reinforcing ribs is the same as that of the spiral steel belts 2, at least 3 flat steel belts are wound in parallel and cover the positions between the spiral steel belts 2 as far as possible, and the width of the selected flat steel belt is selected according to the width between the spiral steel belts 2.
The strengthening rib 4 is circular steel wire, and the steel wire material is the same with spiral steel band 2, because the steel wire diameter is less, the steel wire quantity that adopts chooses for use according to the width between the spiral steel band 2.
Examples
As shown in fig. 2 to 6, the winding of the spiral steel strip 2 and the filling of the first filling layer 3 may be performed simultaneously during the production process, and the spiral steel strip 2 and the corrugated pipe liner are completely covered by hot melt coating; similarly, the second coating layer 5 may be applied while the reinforcing beads 4 are wound, and the reinforcing beads 4 and the first coating layer 3 may be completely covered by hot melt coating. The reinforcing ribs 4 are wound along the spiral direction of the grooves between the spiral steel strips 2 and are wound on the spiral corrugated pipe in parallel with the spiral steel strips 2.
During the installation, when meetting great bend, HDPE steel band reinforcing helical bellows toughness is better, can move towards the natural bending along with the bend, the clearance has been reserved in setting up of its strengthening rib 4, bellows inside lining 1 and the first filling and covering layer 3 of pipeline are not covered completely to the axial, bellows inside lining 1, the toughness and the life of pipeline can be guaranteed well to first filling and covering layer 3 and second filling and covering layer 5, and the compressive strength of position between 2 again can be guaranteed to strengthening rib 4 pipeline helical steel band, difficult impaling or taking place local cave in, HDPE steel band reinforcing helical bellows's whole ring rigidity obtains promoting.
The reinforcing ribs 4 can be flat steel belts or round steel wires, the flat steel belts or the round steel wires can well protect the positions between the spiral steel belts 2 of the HDPE steel belt reinforced spiral corrugated pipe, but the winding process of the flat steel belts is easier to realize, and the round steel wires can enable the overall flexibility of the pipeline to be better.
The above-mentioned embodiments are merely exemplary, so as to enable those skilled in the art to better understand the technical solution, and should not be construed as limiting the scope of the present invention, and all modifications and simple substitutions made according to the technical solution of the present invention fall within the scope of the present invention.
