Description

[0001] Device and method for connecting and separating pipes with a socket

[0002] The invention relates to a device and a method according to the preambles of the independent patent claims.

[0003] Various devices for connecting pipes are known from the prior art. Among other methods, one person drives a pipe in the desired direction, for example using a mallet and a piece of wood or a mallet and a shovel, to create a tight connection with another pipe, while a second person holds the pipe in position. The disadvantage of this conventional method, however, is that the pipe is often damaged by the mallet and that two people are always required. Furthermore, the seal provided in the pipes can easily slip, preventing a tight connection.

[0004] For example, devices are also known in which, in order to tightly connect the pipes to one another, different parts of the device must first be attached to the pipes to be connected. The disadvantage of such devices is that attaching the device parts to the pipes is time-consuming. Furthermore, in practice, the use of such a device may not be possible because the spatial conditions do not permit it, in particular because there is insufficient space available to arrange the device parts on the pipes, especially in a trench, in an excavation pit, or in a confined space.
