Abstract
The utility model discloses a polyethylene winding structure wall pipe with reinforcing inner ribs and reinforcing steel strips. The polyethylene winding structure wall pipe with the reinforcing inner ribs and the reinforcing steel strips comprises a hollow cylindrical polyethylene body and spiral reinforcing ribs, wherein the spiral reinforcing ribs encircle the outer wall of the pipe body. At least one reinforcing inner rib is installed in the spiral reinforcing ribs, wherein the reinforcing inner rib is connected with the outer wall of the pipe body. Reinforcing steel strips are inserted in the reinforcing inner ribs. The steel strips are inserted in the reinforcing inner ribs of the polyethylene winding structure wall pipe with the reinforcing inner ribs and the reinforcing steel strips. The steel strips are wrapped in a protecting reinforcing cavity, wherein the protecting reinforcing cavity is circular and provided with inner ribs. The steel strips are in a double protection completely. A condition that steel strips are exposed in transportation, installation and construction process can be avoided, wherein the condition is caused by destroying of coating layers polyethylene (PE). Security and service life of products can be guaranteed. Quality and ring stuffiness of the structure wall pipe are improved greatly.
Description
Technical field
The utility model belongs to large-bore plastics tubing technical field, is specifically related to a kind of polyethylene spirally enwound structure-wall tubular product.
Background technique
At present, oneself relates to industry-by-industry the application of the kind of plastic pipe, the various water delivery plastic tubes (U-PVC, PE, PP-R, PB, PVC-O, PVC-M etc.) that have tap water to use; The various plastic tubes (PVC-U riffled tube, PE double-wall corrugated pipe, PVC-U double-wall corrugated pipe, PE hollow wound pipe, PE steel band reinforced winding pipe, PE steel strip reinforced riffled tube etc.) that have the draining blowdown to use; Be useful on the power communication protecting jacket and use (sheathed casings such as U-PVC, C-PVC, M-PP, HDPE silicon core pipe); Be useful on non-excavating construction and use (HDPE, M-PP pipe), the most of plastic tube that adopts of the pipe of in Municipal Industry, using.
The effective way of polyethylene spirally enwound structure-wall is wide, and its good shock resistance of ability, pliability with extremely strong chemical resistance corrosion and erosion is strong, lightweight, and easy construction, wear-resisting property are strong, long service life, sanitation performance are good.But because the polyethylene elastomer modulus is little, the ring stiffness of polyethylene spirally enwound structure-wall tubular product can't satisfy the usage requirement of heavy-caliber plastic pipe.For increasing its ring stiffness, use at outer pipe wall increases the steel band structure more at present, carries out polyethylene and steel band compound to obtain to encircle preferably stiffness.But, because of thinner in the compound PE of steel strip surface, in the processes such as transportation and installation, be easy to clad PE is damaged, in case PE has crack, destruction can cause steel band exposed, the sewage that tubing is carried can produce corrosion to steel band, steel band loses due intensity, and the contingencies such as the road surface subsides, sewage exposes very easily occur.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of polyethylene spirally enwound structure-wall tubular product that stiffness can satisfy the usage requirement of heavy caliber draining drain pipe that encircles.
For solving the problems of the technologies described above, a kind of polyethylene spirally enwound structure-wall tubular product with strengthening internal-rib and enhancing steel band of the present utility model, comprise hollow cylindrical polyvinyl piping materials body and the spiral reinforcing rod that is looped around described tubing body outer wall, be provided with at least one enhancing internal-rib that is connected with tubing body outer wall in the described spiral reinforcing rod, described enhancing internal-rib is embedded with steel band.
Be provided with one in the described spiral reinforcing rod perpendicular to the enhancing internal-rib of tubing body, this enhancing internal-rib is divided into two semicircular hollow cavities with described spiral reinforcing rod.
For the ring stiffness that further improves tubing to satisfy the usage requirement of heavy caliber draining drain pipe, be provided with two in the described spiral reinforcing rod and strengthen internal-rib, these two strengthen internal-rib and all are 30～90 with the outer wall of tubing body and spend angles, and described spiral reinforcing rod is divided into three hollow cavities.
Being embedded in the steel band quantity that strengthens in the internal-rib can increase and decrease according to enhancing internal-rib quantity actual in the tubing, and when the enhancing internal-rib in the spiral reinforcing rod was one, the steel band that is embedded in this enhancing internal-rib was 1; When the enhancing internal-rib in the spiral reinforcing rod is two, all embed steel band in every enhancing internal-rib.
For obtaining best ring stiffness and reducing poly wearing and tearing, the height of described steel band is 1:3～1:1 with the ratio of the height that strengthens internal-rib, and the width of described steel band is 20%～90% of the width that strengthens internal-rib.
To increase the ring stiffness different from " carat pipe " in the prior art used bellows round structure, and the utility model is used has the profile structure of enhancing internal-rib in being, thereby has better epistasis modulus, can obtain better to encircle stiffness; Simultaneously; the utility model has embedded steel band in strengthening internal-rib; steel band is wrapped in the protection enhancing die cavity of circle with internal-rib; steel band is in the double shielding fully; effectively prevented from destroying the generation that causes the exposed situation of steel band because of clad PE in the processes such as transportation and installation; guarantee Security and the working life of product, significantly promoted quality and the ring stiffness of structure-wall pipe material, can satisfy ring stiffness 12.5KN/M
2The usage requirement of above heavy caliber pipe.
