Description
Technical Field
The utility model relates to a tubular product technical field, concretely relates to directional crooked bellows.
Background
Plastic pipes of various forms are increasingly used in sewer pipes and various sewage pipes in cities. Because the pipe is not internally provided with pressure when drainage or pollution discharge is not carried out, in order to improve the performance of resisting external pressure or impact, plastic pipes with different forms of reinforcing rib structures arranged on the periphery of the pipe wall are used. At present, the plastic pipes with the structural forms and the corresponding preparation methods can be as follows: a plastic pipe which is directly extruded and molded. The most representative of the pipe is a double-wall corrugated pipe and a hoop ribbed pipe which are directly extruded, wherein the inner wall layer is a continuous smooth surface, and the outer wall layer is a hollow wave structure or a solid annular rib structure respectively. During manufacturing, the inner wall layer of the pipe is a continuous pipe formed by extruding plastics in a molten state; as the outer wall layer of the rib structure, under the condition that the plastic of the inner wall layer of the pipe is not completely cooled, the corresponding 'wave trough' part of another continuous rib structure layer with a proper structure form such as hollow wave form or annular rib is welded on the outer circumferential surface of the pipe wall.
The existing inner rib reinforced corrugated pipe is formed by winding and bonding a plurality of strips, for example, patent documents with patent numbers of CN201310290104.6 and publication date of 2015.01.14 disclose a continuous winding reinforced corrugated pipe and a preparation method thereof, wherein the pipe comprises a continuous solid-wall cylindrical pipe body formed by mutually overlapping and fusing a plurality of spirally wound special-shaped strips with butt-joint fins on two sides through the fins, the pipe wall of the cylindrical pipe body is spirally and circularly provided with a plurality of hollow reinforcing ribs, each hollow reinforcing rib comprises at least one special-shaped single-wall corrugated reinforcing pipe spirally wound and arranged on the pipe wall of the cylindrical pipe body through a reinforcing bonding layer and an outer reinforcing layer spirally wound and pressed on the special-shaped single-wall corrugated reinforcing pipe in a spanning manner, and two ends of the reinforcing layer are bonded with the pipe wall of the cylindrical pipe body; the central line of the hollow reinforcing rib is superposed with the central line of the mutually overlapped and fused forming part of the wing pieces of the adjacent special-shaped strip.
However, according to the inner rib reinforced spiral corrugated winding pipe disclosed in the patent document, in the production process of the continuously wound reinforced corrugated pipe material, when the reinforcing rib structure is bonded to the pipe body, the reinforcing rib structure needs to be bent and attached to the surface of the pipe material, and at this time, due to the elastic effect of the reinforcing rib structure, the reinforcing rib structure is prone to incline leftwards or rightwards in the winding direction of the reinforcing rib, so that the bearing capacity of the reinforcing rib structure is reduced, the ring stiffness of the pipe body is further reduced, the bearing capacity of the pipe body is reduced, and the service life of the pipe material is shortened.
