Esquema de construcción de suministro de agua enterrada municipal de tubería de PE: conexión de fusión en caliente y respuesta de asentamiento

2025-08-18


PE la tubería se usa ampliamente en el suministro de agua enterrada municipal debido a su resistencia a la corrosión y gran flexibilidad. Durante la construcción, es necesario concentrarse en controlar la calidad de la conexión de fusión en caliente y las medidas de asentamiento para garantizar un funcionamiento estable a largo plazo del sistema de suministro de agua. La conexión de fusión en caliente

es el proceso de conexión central de la tubería de PE y es necesario seguir estrictamente las especificaciones de operación. Antes de la construcción, se debe verificar la apariencia de la tubería para asegurarse de que no haya rasguños, depresiones y que el puerto sea plano. Cuando se utiliza una soldadora de fusión en caliente especial, la temperatura de calentamiento (generalmente 19010 ° C) y el tiempo de calentamiento deben configurarse de acuerdo con las especificaciones del diámetro de la tubería. Después de que la placa calefactora muestre un estado fundido uniforme, conecte rápidamente la tubería y mantenga la presión especificada hasta que la interfaz se enfríe y solidifique. Una vez completada la conexión, es necesario verificar si la interfaz ha formado una brida uniforme, sin soldadura virtual, fenómeno de soldadura por fugas y realizar una prueba de presión si es necesario. La presión de prueba no es inferior a 1,5 veces la presión de trabajo y se califica la retención de presión durante 30 minutos sin caída de presión.

Para los problemas comunes de asentamiento de cimientos en la construcción municipal, las medidas de prevención y control deben tomarse desde múltiples enlaces de diseño y construcción. Antes de la colocación de tuberías, se debe realizar un estudio geológico y la capa de suelo blando debe tratarse con con arena graduada y reemplazo de grava, y el grado de compactación debe superponerse al 90%. La base de la tubería debe estar hecha de un cojín de arena de 150 mm de espesor y se deben agregar muelles de soporte de hormigón en la interfaz para el refuerzo. Al rellenar, suelo liso o arena con se debe seleccionar un tamaño de partícula de 50 mm, y la altura de relleno en capas no debe exceder los 300 mm. Se debe usar un rodillo ligero para compactar y evitar el rodado mecánico directo de la tubería. Para tramos de carretera cruzados o áreas geológicamente complejas, se pueden colocar "puentes de tubería" o se pueden configurar compensadores de fuelle para compensar la tensión de asentamiento utilizando la flexibilidad de la propia tubería de PE.

el proceso de construcción también debe prestar atención al ajuste de adaptación ambiental. Durante la construcción en invierno, la tubería debe precalentarse a más de 5 ° C antes de la conexión de fusión en caliente para evitar grietas quebradizas a baja temperatura; durante las altas temperaturas en verano, se deben tomar medidas de sombreado para evitar la expansión y deformación térmica de la tubería. Al mismo tiempo, haga registros de construcción, incluidos los parámetros de fusión en caliente, los datos de tratamiento de cimientos, los resultados de observación de asentamiento, etc., para formar un archivo técnico completo que brinde una base para su operación y mantenimiento posteriores. A través de la aplicación científica de la tecnología de conexión de fusión en caliente y la tecnología de prevención y control de asentamiento, la seguridad y durabilidad del sistema de suministro de agua de tubería de PE se pueden mejorar de manera efectiva para satisfacer las necesidades de operación a largo plazo de la ingeniería municipal.
