简论变电所穿墙预埋管渗水漏水封堵方法

电缆是供电设备与用电设备之间连通的桥梁,起到传输电能的作用,电缆一般穿过墙体中预埋钢套管结构连接供电设备和用电设备.在工程实践中经常出现电缆和钢管间隙封堵不严密,雨水通过间隙进入变电所内,导致变电所内电缆沟出现大量积水,给日常运行管理造成不便,对电缆和变电所内电气设备安全运行造成威胁.施工过程中,受施工环境、自然条件限...

Brief Introduction to Sealing Methods against Water Seepage and Leakage of Embedded Pipe through Wall in Substation

Cable serves the bridge between power supply facility and electrical equipment, and transmits electric power. The cable generally passes through the steel sleeve structure embedded in wall so as to connect the power supply facility with the electrical equipment. In some projects, the gap between the cable and the steel pipe is not tightly sealed, which allows rainwater to enter the substation, the flooded cable trench in the substation influences normal operation and management, and threatens the operation of the cable and the electrical equipment in the substation. In the construction, many factors such as natural conditions, construction environment and management lead to different sealing methods and results. Based on the completed projects, for example, the water leakage of the embedded pipe, the problems existing in the sealing process are analyzed, different plugging plans and materials are compared to determine the suitable one through simulation tests. The above research strengthens the management of construction technology against water seepage and leakage, helps to grasp the technical essentials, and further improves the construction quality. The research results will provide a reference for similar technical management.
