    • An access pipe for connecting to a rainwater pipe (10, 11) or the like is described. The access pipe comprises an outer tubular section (1) and an inner tubular section (2) nested at least partially within the outer tubular section. An access aperture is provided in the inner tubular section such that in use, the rainwater pipe can be inspected and a rod can be inserted into the rainwater pipe for cleaning. The access aperture is covered by the outer tubular section and relative movement is permitted between the inner and outer tubular sections such that in use, the access aperture may be covered and uncoverd easily. In one embodiment the outer tubular section contains a second access aperture corresponding to the first access aperture; in this case rotary motion between the inner and outer tubular sections is possible. In another embodiment the outer tubular section is arranged to slide over the access aperture in a direction substantially parallel to the axis of the tubular sections.
    • 描述了用于连接到雨水管(10,11)等的进入管。 进入管包括外部管状部分(1)和至少部分地嵌套在外部管状部分内部的内部管状部分(2)。 在内部管状部分设有进入孔,使得在使用中可以检查雨水管,并且可以将杆插入雨水管中进行清洁。 进入孔被外部管状部分覆盖,并且允许在内部管状部分和外部管状部分之间进行相对运动,使得在使用中可以容易地覆盖和暴露出进入孔。 在一个实施例中,外管状部分包含对应于第一进入孔的第二进入孔; 在这种情况下,内管段和外管段之间的旋转运动是可能的。 在另一个实施例中,外管状部分布置成在基本上平行于管状部分的轴线的方向上滑动进入孔。
