Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral wound pipe technology, and in particular to a double high-strength reinforced polyethylene (HDPE) spiral wound pipe for underground use. Background Technology
[0002] With the acceleration of urbanization and the continuous upgrading of infrastructure construction, the performance requirements of underground pipeline systems are increasing. Traditional pipeline materials such as concrete pipes and steel pipes have problems such as heavy weight, poor corrosion resistance, and complex construction, making it difficult to meet the demands of modern engineering for high efficiency, environmental protection, and durability. Against this backdrop, double-high-strength reinforced polyethylene spiral wound pipe has emerged.
[0003] However, some existing double-high-strength reinforced polyethylene spiral pipes have poor seismic resistance and are not strong enough when used underground.
[0004] Therefore, in order to address the above problems, a double-high-strength reinforced polyethylene (HDPE) spiral pipe for underground use is now being developed. Utility Model Content
[0005] In order to overcome the shortcomings of existing double-high-strength reinforced polyethylene spiral pipes, which have poor seismic resistance and are not strong enough when used underground, this utility model provides a double-high-strength reinforced polyethylene HDPE spiral pipe for underground use.

[0007] Optionally, the first high rib is composed of a first inner side, a second outer side, a first top side, and a first bottom side, and the second high rib is composed of a second inner side, a second outer side, a second top side, and a second bottom side.
[0008] Optionally, the thickness of the first inner side and the second inner side is 3.8 mm, the thickness of the first outer side and the second outer side is 3.8 mm, the thickness of the first top side and the second top side is 3.6 mm, and the thickness of the first bottom side and the second bottom side is 3.6 mm.
[0009] Optionally, the connector is further comprising having a thickness of 4 mm, a length of 37 mm, and a height of 42 mm for the first and second high ribs.
[0010] Optionally, it also includes a first outer arc at each of the four corners of the outer edge of the first rib, the diameter of the circle formed by the first arc being 5mm, and a second outer arc at each of the four corners of the outer edge of the second rib, the diameter of the circle formed by the second arc being 5mm.
[0011] Optionally, it also includes a first inner arc at each of the four corners of the inner cavity of the first high rib, the diameter of the circle formed by the first inner arc being 3mm.
[0012] Optionally, the connector is further provided with a third arc at the connection between the connector and the first inner side and the second inner side. The diameter of the circle formed by the third arc is 5mm. The first outer side is set at a right angle to the first top side and the second top side. The second outer side is set at a right angle to the second top side and the second top side. The first inner side is set at an inclined angle of 10°. The second inner side is set at an inclined angle of 10°.
[0013] This utility model has the following advantages:
[0014] By providing arcs on the outer sides of the first and second high ribs and on the sides of the hollow cavity, external pressure is prevented from acting directly on the high ribs, thereby increasing the compressive strength of the double high rib reinforced polyethylene HDPE spiral pipe. It also reduces unnecessary structures, thus reducing the overall weight of the double high rib reinforced polyethylene HDPE spiral pipe. The connectors make the double high rib reinforced polyethylene HDPE spiral pipe more robust. Furthermore, the first and second inner sides are both inclined, which reduces the stress on the bottom, thereby enhancing the robustness of the double high rib reinforced polyethylene HDPE spiral pipe.

It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside appearing or about to appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0018] like Figure 1As shown, a buried double-high-strength reinforced polyethylene (HDPE) spiral pipe includes a first high-strength rib 1 and a second high-strength rib 2. A connector 3 is provided between the first high-strength rib 1 and the second high-strength rib 2. The two sides of the connector 3 are fixedly connected to the first high-strength rib 1 and the second high-strength rib 2, respectively. The first high-strength rib 1 is composed of a first inner side 101, a second outer side 202, a first top side 103 and a first bottom side 104. The second high-strength rib 2 is composed of a second inner side 201, a second outer side 202, a second top side 203 and a second bottom side 204.
[0019] It should be noted that the hollow inner cavity design reduces the overall weight of the device.
[0020] The thickness of the first inner side 101 and the second inner side 201 is 3.8mm, the thickness of the first outer side 102 and the second outer side 202 is 3.8mm, the thickness of the first top side 103 and the second top side 203 is 3.6mm, the thickness of the first bottom side 104 and the second bottom side 204 is 3.6mm, the thickness of the connector 3 is 4mm, the length of the connector 3 is 37mm, the height of the first high rib 1 and the second high rib 2 is 42mm, the first outer side 102 arc is provided at the four corners of the outer edge of the first high rib 1, and the diameter of the circle formed by the first arc is 5mm, the second outer side 202 arc is provided at the four corners of the outer edge of the second high rib 2, and the diameter of the circle formed by the second arc is 5mm, the first inner side 101 arc is provided at the four corners of the edge of the inner cavity of the first high rib 1, and the diameter of the circle formed by the first inner side 101 arc is 3mm.
[0021] It should be noted that by providing arcs on the outer sides of the first high rib 1 and the second high rib 2 and on the side of the hollow cavity, external pressure is prevented from acting directly on the high ribs, thereby increasing the compressive strength of the double high rib reinforced polyethylene HDPE spiral pipe and reducing unnecessary structures, thus reducing the overall weight of the double high rib reinforced polyethylene HDPE spiral pipe. The connector 3 can make the double high rib reinforced polyethylene HDPE spiral pipe more robust overall.
[0022] A third arc is provided at the connection between the connector 3 and the first inner side 101 and the second inner side 201. The diameter of the circle formed by the third arc is 5mm. The first outer side 102 is set at a right angle to the first top side 103 and the second top side 203.

The second inner side 201 is set at an inclined angle of 10°.
[0023] It should be noted that both the first inner side 101 and the second inner side 201 are set at an angle, which can reduce the stress on the bottom and thus enhance the firmness of the double high-strength reinforced polyethylene HDPE spiral pipe.
