Problems solved by technology

If the sub-pipe is placed directly into the main pipe, it will often cause loosening and displacement, which will easily affect the construction quality. At the same time, the wall of the central hole surrounded by the sub-pipe is curved, which wastes materials and has low extrusion resistance.

Abstract

The invention relates to a pressure-tolerant communication perforated pipe. According to the perforated pipe, the problem that a secondary pipe and a main pipe of a present communication perforated pipe are not firmly connected and materials are wasted is solved. The pressure-tolerant communication perforated pipe comprises a main pipe, secondary pipes, a connector and positioning pins. The secondary pipes include five circular pipes with equal diameters. Centers of the five circular pipes with equal diameters are at the same circumference, and two adjacent circular pipes are tangent to each other and are integrated as a whole. A centre hole encircled by the five circular pipes has a regular pentagon structure. The secondary pipes are arranged in the main pipe. The connector is arranged at the end portion of the main pipe. Location holes are disposed along the axial direction of the connector, the main pipe and the secondary pipes. The positioning pins pass through the location holes to connect the connector, the main pipe and the secondary pipes together. According to the pressure-tolerant communication perforated pipe provided by the invention, the secondary pipes and the main pipe are connected fixedly and firmly. The pressure-tolerant capability of the perforated pipeline is strong.

Description

technical field [0001] The invention relates to the communication field, in particular to an extrusion-resistant porous tube for communication. Background technique [0002] Electric cable pipe is also known as electric power pipe, cement cable pipe and so on. The outstanding features of the power cable tube are high strength and small frictional resistance, which is 40% higher than ordinary tubes. The flexural load of the tube body is ≥12000N, and the external pressure load is ≥15000N. It can be used for road laying of various levels. The inner wall and cables Small friction resistance is the most prominent advantage of power cable tubes, and its friction coefficient is <0.35, which is obviously lower than other types of cable tubes such as glass fiber reinforced plastics and PVC. When the cable is passed, the number of wells is reduced, the engineering cost is reduced, and the cable pulling length is increased. [0003] At present, the porous pipes used for laying com...
