On site teaching of sealing for the Yunxiao Civil Low Voltage Reconstruction Project

2020-02-09

The civil low-voltage renovation project of Zhangzhou Yunxiao Power Supply Company has a heavy workload. In order to complete the cable hole sealing renovation project as soon as possible, each construction team has worked overtime, and our company has also sent professional technical personnel to provide on-site teaching guidance. For various special situations of reserved pipelines and cable threading pipelines, different sealing devices are used for sealing. The following is a representative image taken by the company's technical personnel on site before sealing. The reserved pipeline left by the construction on the left and a cable threading pipeline on the right are both cases where we need to seal these holes. The reasons for sealing are as follows: Firstly, for reserved pipelines, sealing the opening can ensure that mud, rainwater, and other substances leak into the well through the pipeline, causing water accumulation and other problems, and causing trouble in subsequent underground well maintenance such as pumping. Blocking the reserved pipeline can maintain a dry environment inside the well, while also preventing small animals such as rats and ants from wandering around in the interconnected pipeline, leaving corpses that can cause blockage to the pipeline. It is appropriate to use the hollow pipeline sealing plug as a sealing device, which is specifically designed for sealing empty pipes. It is not only aesthetically pleasing, but also reusable and has a high cost-effectiveness. 2、 For cable through wall pipelines, it is also necessary to block them. 1. It can avoid the adverse effects of accumulated water, sediment, mice, etc. on the pipeline environment, providing a relatively clean and dry working environment for manual underground operations or underground pipeline construction; 2. It can achieve waterproof, rat proof, and anti-theft effects, better protect cables from external factors, and reduce cable accident rates; 3. After segmented sealing of the pipeline, the problem of pipeline flow is avoided, which can greatly reduce the trouble and time of manual well pumping and dredging, and improve operational efficiency.
