Protective structure and method for dissipating tensile load applied to a support cable in a support cable arrangement of the protective structure
The present disclosure relates to a protective structure having a plurality of supports arranged spaced apart from each other; having a trapping device which is guided on the supports via at least one support cable arrangement; and having a ground anchorage for free ends of the at least one support cable arrangement. The ground anchorage is designed as a deadman anchorage.
1. A protective structure, comprising:
a plurality of supports arranged in a manner spaced apart from and adjacent to each other;
a trapping device guided on the supports via at least one support cable arrangement; and
a ground anchorage for free ends of the at least one support cable arrangement;
wherein the ground anchorage is configured to operate as a deadman anchorage; and
wherein the plurality of supports comprises buriable base arrangements each surrounded by an erosion protection device.
2. The protective structure according to claim 1 , wherein the deadman anchorage has a deadman anchor.
3. The protective structure according to claim 2 , wherein the deadman anchor(s), respectively, are formed in a cube-shaped, cone-shaped or plow-shaped manner.
4. The protective structure according to claim 2 , wherein the deadman anchor is configured to be pulled through the surrounding soil material by the support cable arrangement.
5. The protective structure according to claim 2 , wherein the deadman anchor is placeable in a buriable and fillable tube.
6. The protective structure according to claim 1 , wherein the deadman anchorage has a plurality of deadman anchors connected to each other.
7. The protective structure according to claim 1 , wherein the erosion protection device comprises a net or net arrangement.
8. The protective structure according to claim 1 , wherein the erosion protection device comprises a gabion structure.
9. A method for dissipating a tensile load applied to a support cable of a support cable arrangement of a protective structure, the method comprising:
arranging a plurality of supports spaced apart from and adjacent to each other;
surrounding buried base arrangements of each of the plurality of supports by an erosion protection device;
guiding a trapping device on the plurality of supports via the support cable arrangement;
connecting a free end of the support cable of the support cable arrangement to a deadman anchor;
placing the deadman anchor and a rope portion adjoining the free end in soil material of a mounting region of the protective structure; and
applying a tensile load to the support cable and pulling the deadman anchor through the soil material.
10. The method according to claim 9 , wherein the deadman anchor remains in the soil material when being pulled therethrough.
11. The method according to claim 9 , wherein performance of the deadman anchor is adjustable by selecting a shape of the deadman anchor.
12. The method according to claim 9 , wherein performance of the deadman anchorage is adjustable by selecting a material surrounding the deadman anchorage.
13. The method of claim 9 , wherein surrounding the buried base arrangements of each of the plurality of supports by the erosion protection devices comprises surrounding the buried base arrangements of at least one of the plurality of supports by a net or net arrangement.
14. The method of claim 9 , wherein surrounding the buried base arrangements of each of the plurality of supports by the erosion protection devices comprises surrounding the buried base arrangements of at least one of the plurality of supports by a gabion structure.
