The special loads during lifting and transport of the pipes must be taken into account. In particular, transport via a centric stop (cast-in anchor or centrally positioned pipe gripper) activates bending loads for which the pipes must be dimensioned. For pipes with smaller pipe diameters, it is advisable, if possible, to support the pipe via the outer pipe wall or from the inner pipe wall. (Image: Transport of a pipe with a centrally positioned pipe … |

To facilitate the jointing of the pipes, the socket area should be greased in advance. The lubricant used must be free of plasticizers or other ingredients that could damage the compression seal. Important: Attention: Only the lubricant permitted by the manufacturer may be used.

The water replacement test method is used in coarse-grained sands, gravelly sands, in mixed soils (slope debris) in which stable pits can be excavated. Water replacement with the help of a plastic film or soft rubber skin allows to measure the volume in very permeable coarse-grained soils. The volume of the test pit (Vg) is determined from the mass of water required (difference weighing of the bucket before and after) and from the density of the liquid … |
