Referring to fig. 1 together, the HDPE porous plum blossom pipe provided by the present utility model will now be described. The HDPE porous plum blossom pipe comprises an outer pipe 10, a sub pipe 20, a middle pipe 30 and a supporting plate 40. The sub-tubes 20 are arranged in a plurality, each sub-tube 20 is annularly arranged in the outer tube 10 at intervals around the axis of the outer tube 10, the tube wall of each sub-tube 20 is intersected and fused with the tube wall of the outer tube 10, and a connecting position is formed between any two adjacent sub-tubes 20. The intermediate tube 30 is disposed in the region surrounded by the sub-tubes 20 and is disposed in line with the axis of the outer tube 10, and the tube wall of the intermediate tube 30 intersects and merges with the tube wall of the sub-tubes 20. The support plates 40 are provided in plurality, each support plate 40 is arranged in one-to-one correspondence with each connecting position, one end of each support plate 40 is connected with the pipe wall of the outer pipe 10, and the other end is connected with the corresponding connecting position.

Wherein the wall thickness of the intermediate tube 30 is greater than the wall thickness of each sub-tube 20.

The working principle of the HDPE porous quincuncial pipe provided in this embodiment is that after the outer pipe 10 receives external pressure, the external pressure is directly transmitted to the connecting position through the corresponding support plate 40, and the external pressure is continuously transmitted to the middle pipe 30 through the connecting position. Therefore, in the direction of the compressive force, the compressive force is mainly shared on the intermediate tube 30 and the corresponding support plate 40, so that the sub-tube 20 can be protected, and the compressive strength can be ensured.

Compared with the prior art, the HDPE porous plum blossom pipe provided by the embodiment can form a protection layer on the periphery of each sub-pipe 20 through the arrangement of the outer pipe 10 so as to ensure the protection of each sub-pipe 20 and further protect a cable. The middle pipe 30 is arranged in the surrounding area of each sub pipe 20 and is in cross fusion with each sub pipe 20, so that the support of each sub pipe 20 together with the outer pipe 10 can be ensured, the stability of each sub pipe 20 is further ensured, the pressure received by the outer pipe 10 can be ensured to be dispersed to the sub pipe 20 through the arrangement of each supporting plate 40, and meanwhile, the pressure is transmitted to the middle pipe 30, and the middle pipe 30 can be ensured to bear larger pressure due to larger wall thickness of the middle pipe 30, so that the compressive strength is ensured, meanwhile, the middle pipe 30 can also be penetrated with a cable, the utilization of resources is ensured, and the practicability is strong.

In some embodiments, the sub-pipe 20 may have a structure as shown in fig. 1. Referring to fig. 1, the walls of any two adjacent sub-tubes 20 are cross-fused.

Wherein the connection position is the joint of two adjacent sub-tubes 20.

The pipe walls of two adjacent sub-pipes 20 are crossed and fused, so that the material saving of the molding of the two sub-pipes 20 can be ensured, and the connection stability of the two sub-pipes can be ensured. And the connection can ensure that the pressure of the supporting plate 40 is respectively shared on the two sub-tubes 20, thereby ensuring the uniformity of stress.

In this embodiment, a triangular area is formed between the middle tube 30 and any two adjacent sub-tubes 20, and the force of the support plate 40 can be directly transferred to the corresponding outer wall of the area due to the stability of the triangle, so as to ensure the protection effect on other sub-tubes 20.

In some embodiments, the support plate 40 may have a structure as shown in fig. 1. Referring to fig. 1, each support plate 40 is disposed along the radial direction of the outer tube 10, because after the outer tube 10 is stressed, the support plates are disposed along the radial direction of the outer tube 10 except for concentrated stress, so that the structure can adapt to the stress condition of the outer tube 10, and has the advantages of simple structure, convenient manufacture and strong practicability.

In some embodiments, the support plate 40 may have a structure as shown in fig. 1. Referring to fig. 1, an arc angle is arranged between each support plate 40 and the pipe wall of the outer pipe 10, because after the outer pipe 10 receives an external force, the arc angle is transmitted to the support plates 40, and the contact area between the support plates 40 and the outer pipe 10 can be increased, so that stress concentration can be effectively prevented, and the outer pipe 10 is protected, so that the practicability is strong.
