Method and apparatus for constructing a closed sheeting system

摘要

The present invention removes the obvious disadvantages present in the prior art and permits the construction of a short and self-contained sheeting system. By the use of a special corner section (1) which is disposed in the longitudinal direction of the trench and can be moved in the vertical direction by means of the inner (2) and outer pressure beam (3), end sheeting (6), consisting, for example, of individual horizontal sheeting elements, is connected to the longitudinal sheeting (12) located in the longitudinal direction of the trench and is continuously pressed in or withdrawn with the excavation or filling of the trench. The sheeting box can be varied in its width by the telescopic facility of the respective end support of the bottom guide (5) and end sheeting elements of different length. <IMAGE>
