Trenches are used to take up, store and release a fluid, especially rainwater. A shaft is provided for access to such a trench so that inspections, maintenance and cleaning of the trench can be carried out from there. These shafts are complex to manufacture from polymer material, in which they are either welded together from semi-finished products, or are produced in a blow molding process or in a rotary sintering process. In the blow molding process and the rotary sintering process in particular, the wall thicknesses of the shaft or shaft element are uneven, so that either the stability of these shafts or shaft elements is in need of improvement, or - in order to counteract this - a high wall thickness must be formed, which requires increased use of material.

The shaft for a trench made of shaft elements that are made from a number of components can be designed to be particularly stable in this way. In this way, appropriate precautions can also be taken to ensure that the connection of the components to one another to form the shaft element is very solid.

This makes it possible to overcome the disadvantages of the stand and to provide a shaft made of shaft elements, made from structural elements, which requires the least amount of material with maximum stability.

In the simplest embodiment of the present invention, the shaft for a trench comprises two identical shaft elements which are connected to one another to form the shaft.

Within the scope of the present invention, it is also possible for further shaft elements to be arranged on this shaft made up of two shaft elements and to be connected to it or to an adjacent shaft element.

The measure described above makes it possible to produce a shaft or a shaft element in a simple manner by connecting individual components. In particular, such a shaft or such a shaft element can be assembled in this way from four individual identical components, which are each connected to one another at an angle of 90 ° or approximately 90 °.

A very favorable further development of the present invention can consist in that the component is designed in such a way that the third connecting means on the fifth side and the fourth connecting means on the sixth side are designed so that they are congruent to one another when a connection state is established between two adjacent ones Components these are arranged in alignment or approximately in alignment with respect to the orientation of the respective first side of the components.
