为确保管道的正常输水,有时须在承插式异形管处砌筑支墩,以克服管内水压在该处产生的推力,避免接口松脱。支墩的类型和尺寸要根据异形管的类别、布置方式、管径、内水压力、土质条件、覆土及现场情况而定。一、异形管支墩的类型根据异形管在管道中布置的方式,常用的支墩类型有以下几种: (一)水平支墩水平支墩是指水平方向的异形管支墩。按照异形管的类别,又分:
In order to ensure the normal pipeline water, and sometimes have to be inserted in the socket-shaped pipe mound pier to overcome the pressure generated in the tube where the thrust to avoid the interface loose. The type and size of the pier should be based on the type of shaped pipe, arrangement, diameter, water pressure, soil conditions, casing and on-site conditions. First, the type of shaped pipe pier According to the shape of the pipe in the pipeline layout, commonly used pier types are the following: (A) horizontal pier The horizontal pier refers to the horizontal direction of the shaped pipe pier. In accordance with the type of special-shaped tube, and points:
