Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of winding pipes, in particular to a reinforced polyethylene winding pipe. Background Art
[0002] Spiral pipe is made by spirally wrapping extruded plastic strips around a rolling device and bonding them together to form a single structure. It is often used as a drainage pipe. Drainage pipes are often buried deep underground and must withstand significant soil pressure, which requires the pipe to have sufficient hoop stiffness. The simplest way to improve hoop stiffness is to increase the pipe wall thickness. However, this increases the material used for the spiral pipe, dramatically increasing production costs. Furthermore, the increased wall thickness increases the overall weight of the spiral pipe, making it difficult to transport and install.
[0003] In the prior art, people set reinforcing ribs on the surface of the pipe body to improve the ring stiffness of the pipe body. However, in actual use, when filling soil, the ribs are squeezed by the soil and easily fall over, which affects the ring stiffness of the winding pipe. Utility Model Content

[0005] The utility model provides a reinforced polyethylene winding pipe, comprising:
[0006] tube body;
[0007] The rib tube is spirally wound around the outside of the tube body. The rib tube includes a hollow cladding tube. Support ribs are arranged inside the cladding tube. The support ribs are fitted with the inner surface of the cladding tube. The inner side of the support ribs is also provided with cross-arranged support ribs 1 and 2.
[0008] As a preferred embodiment of the above technical solution, the covering tube is arranged in a closed trapezoidal shape, and the long side of the trapezoid fits the outer surface of the tube body.
[0009] As a preferred embodiment of the above technical solution, the support ribs are arranged in a trapezoidal structure that matches the shape of the inner wall surface of the cladding tube, and one end of the support ribs close to the tube body is open.
[0010] As a preferred embodiment of the above technical solution, the ends of the support rib 1 and the support rib 2 respectively abut against the four corners of the support rib.
[0011] As a preferred embodiment of the above technical solution, the first supporting rib and the second supporting rib divide the interior of the covering tube into multiple cavities.
[0012] The beneficial effects of the utility model are:
[0013] The utility model can improve the ring stiffness of the winding pipe by arranging the ribbed pipe spirally wound around the outer surface of the pipe body; by arranging the support rib, the first support rib and the second support rib, the support rib, the first support rib and the second support rib play a supporting role on the coated pipe, so that the ribbed pipe has a certain strength, thereby preventing the coated pipe from toppling and deforming under the extrusion of the soil body.

[0024] The ribbed pipe 20 is spirally wound around the outer surface of the pipe body 10, which can improve the ring stiffness of the wound pipe; through the arranged support ribs 22, the first support ribs 23 and the second support ribs 24, the support ribs 22, the first support ribs 23 and the second support ribs 24 play a supporting role on the coated pipe 21, enabling the ribbed pipe 20 to have a certain strength, so as to prevent the coated pipe 21 from toppling and deforming under the extrusion of the soil body.
[0025] As Figure 2 , Figure 3 shown, Figure 2 The figure shows a cross-sectional schematic diagram of the wound pipe in the embodiment; Figure 3 The figure shows a structural schematic diagram of the ribbed pipe in the embodiment;

[0028] The support ribs 22 are in the arched structure as Figure 3 shown, and are in contact with the inner wall of the coated pipe 21. The support ribs 22 play a supporting role on the coated pipe 21, reducing the possibility of deformation of the coated pipe 21 when subjected to extrusion force.
[0029] As Figure 3 shown, Figure 3 The figure shows a structural schematic diagram of the ribbed pipe in the embodiment;
[0030] The ends of the first support ribs 23 and the second support ribs 24 respectively abut against the four corner positions of the support ribs 22; the first support ribs 23 and the second support ribs 24 divide the interior of the coated pipe 21 into multiple cavities 25.

As Figure 3 shown, the two are arranged crosswise, and the ends of the first support ribs 23 and the second support ribs 24 respectively abut against the four corner positions of the support ribs 22, and also correspondingly abut against the four corner positions of the coated pipe 21. The distance between the upper ends of the first support ribs 23 and the second support ribs 24 is less than the distance between the lower ends. The first support ribs 23 and the second support ribs 24 play a further supporting role on the coated pipe 21, improving the strength of the coated pipe 21; the setting of the cavities 25 enables the ribbed pipe 20 to also have a certain elastic buffering capacity.
