Description

1

The invention relates to a post according to the preamble of patent claim 1.

Rockfalls and falling rocks are becoming more and more frequent in the Alpine region as a result of climate change and represent natural hazards that must be taken seriously. Due to these natural hazards, there are more and more serious accidents on roads

often resulting in death.

It is known to arrange rockfall protection walls or rockfall protection nets in the vicinity of roadways in the country in order to avoid or reduce the risk of rockfall on vehicles or on the roadway. However, such an installation is usually very complex and time-consuming and is often only

carried out after a rockfall or rock fall.

Usually, after rock falls and rock falls, the endangered roads are closed or secured and extensive rehabilitation measures have to be carried out on the rock from which the rock fall or rock fall occurred. During these rehabilitation measures, the endangered roads often have to be bypassed to a large extent. The rehabilitation of the rock is usually time-consuming, since work has to be carried out in impassable terrain in order to avoid the risk of further damage

To reduce stone falls or rockfalls or to prevent them as best as possible.

The object of the invention is therefore to specify a post of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which operation on a secured road after a rock fall

can be maintained. According to the invention, this is achieved by the features of patent claim 1.

This has the advantage that rockfall protection can be erected quickly and easily on an endangered or secured road and operations on this road can be maintained while the rock is being rehabilitated. If there are already concrete barrier elements on the secured road section, these can be modified easily and quickly using the posts and it can simply be a

Rockfall protection fence to be attached to the posts. Otherwise can

2

Concrete barrier elements can be transported quickly and easily to the endangered road as prefabricated parts. The advantage is that the concrete barrier elements are compact and movable, and after the road has been cleared, the posts can be easily dismantled if this is desired. In combination with the concrete barrier elements or a vehicle restraint system comprising several concrete barrier elements, the safety for road users is additionally increased, since on the one hand the posts with the rockfall protection fences provide stone protection and on the other hand the concrete barrier elements reduce vehicles leaving the road or such accidents. Surprisingly, it has been shown that the uprights in combination with the concrete barrier elements offer a secure hold for the rockfall protection fence and no complex anchoring for the uprights in the subsoil is necessary

is.

The post can be permanently coupled to the concrete barrier element, erected preventively in potentially endangered sections, or erected temporarily after a rockfall until the rock has been repaired and the road is free again. This means that the rock fall or falling rocks must be avoided

affected road should not be bypassed to a large extent. The dependent claims relate to further advantageous configurations of the invention.

Express reference is hereby made to the wording of the patent claims, whereby the claims at this point by reference to the description

are included and are deemed to have been reproduced verbatim.

The invention will be described with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example,

described in more detail. It shows:
