Communication cable protection, the use of seven-hole plum blossom tube in Xiaogan construction site

The seven-hole plum blossom pipe is a porous communication sheathed pipe made of high-density polyethylene as raw material. It is named after the cross-section of seven uniform round holes with a plum blossom distribution. Its main function is to provide outer physical protection for various communication cables to avoid external damage and medium corrosion affecting the service life of the cables. At present, the pipe has been applied in batches at many communication infrastructure and municipal pipeline construction sites in Xiaogan area, and is a common pipe category for local communication cable protection construction.

The core practical advantages of this type of pipe mainly include four points: First, the porous integrated layout improves the construction efficiency. The seven-hole plum blossom pipe adopts a seven-hole integrated molding design, which can accommodate 7 communication cables at the same time in a single laying, without the need for multiple grooves. According to the actual construction data feedback of multiple local construction sites in Xiaogan, the same mileage communication cable laying operation, the use of seven-hole plum blossom pipe can shorten the construction period by about 30%, reduce the time of on-site excavation, and reduce the impact of construction on surrounding road traffic and residents' lives. Second, the weather resistance and damage resistance are adapted to the local construction environment. The pipe material has good impact resistance, corrosion resistance, high and low temperature resistance, and can withstand the climate conditions of high temperature and humidity in summer and low temperature and frost in winter in Xiaogan area. After being buried in the ground, it can resist the long-term erosion of soil acid and alkali and groundwater. It can also withstand the external pressure caused by rolling of conventional construction vehicles and shallow geological subsidence. The cable protection life under normal laying conditions can reach more than 30 years. Third, the low friction design of the inner wall reduces the loss of operation and maintenance. The inner wall of the seven-hole plum blossom pipe is smooth and polished, and the friction coefficient is much lower than that of the conventional hard pipe. During the threading operation, the wear probability of the cable skin can be effectively reduced, and the cable loss during the construction process can be reduced. When the cable needs to be maintained and replaced later, it can also simplify the pulling operation process and reduce the labor and material costs in the operation and maintenance process. Fourth, the general standardized design reduces the adaptation cost. The aperture and interface size of the pipe meet the general construction standards of domestic communication pipes, and can be directly adapted to the pipe joints, seals and other supporting auxiliary materials commonly used in local construction sites in Xiaogan. There is no need to customize special accessories, which can effectively reduce the procurement cost and reduce the adaptation and debugging workload in the construction process.

The current application scenarios of this pipe in Xiaogan area mainly include the laying of communication base station pipelines, the renovation of municipal road communication pipelines, the construction of weak current communication wiring in new residential areas, the construction of communication pipeline networks in industrial parks, and the layout of front-end equipment pipelines in smart cities. The suitable crowd is Xiaogan's local communication engineering construction units, municipal infrastructure contractors, weak current system integrators, park construction operators, and communication pipeline operation and maintenance entities. Purchasing and construction parties with communication cable protection needs.

The production and application of seven-hole plum blossom pipes comply with the relevant quality inspection standards of national communication pipes, and can meet the performance requirements of the communication industry for cable protection after laying. Up to now, there have been many completed communication pipeline projects in Xiaogan area using this type of pipe. After being put into use, the operation state is stable, and there is no batch protection failure. It can be used as a conventional selection product for various construction site communication cable protection.
