Embodiment Construction

[0025] exist Figures 1 to 3 The blocking device shown is arranged in a river or stream with a bed 1 and two banks 2 , 3 . It comprises a bendable barrier element for rocks, floating and drifting objects in the form of a catchment net 4 which extends from the embankment 2 to the embankment 3 with support ropes 5 in the lower part and transverse to the flow direction 7 between the upper support ropes 6. The support ropes 5 and 6 are anchored in the embankments 2, 3 with rope anchors 8, 9 fixed at their ends, so that the rope anchors 9 of the upper support rope 6 are relative to the ropes of the lower support rope 5 in the flow direction. The anchors 8 are offset to the front.

[0026] The catchment net 4 is formed as a bendable ring or helical rope net, which is almost flat in its installed condition before filling up the barrier, and when the barrier is filled up, due to its flexibility Warp upwards into an arch. These two states are in figure 2 , shown schematically in ...

Abstract

The invention relates to a blocking device for a flowing water path and sorts of streams, especially for the torrent or the similar river bed. The device has a bend obstacle component in the way of water integrating net; the component transversely extents from one riverbank to another riverbank. The water integrating net is installed between the lower supporting wire and the upper supporting wire. The supporting wire is anchored on the riverbank by using the wire anchor piece fixing the end part; so that the wire anchor piece of the upper supporting wire biases to the front of the wire anchorpiece of the lower supporting wire corresponding to the flowing direction. In that way, when obstacle is filled, the water integrating net is deformed so that the water flowing out of the net, the rock, floating object are temporarily contact to the water integrating net or never contact to the water integrating net at all. In that way, the invention has great security and permanently avoids the erosion and wearing effect for the flowed water.

Description

technical field [0001] The present invention relates to blocking devices for flowing waterways and streams of all kinds, especially for rapids and similar riverbeds, having bendable obstruction elements for rocks, floating and drifting objects, which can be erected in a direction transverse to the direction of flow between the embankments. Background technique [0002] A blocking device of this type is described in German patent application DE20300821. Devices of this type are known to reduce the energy of flowing water in order to create protection against the destructive effects of flood rapids, and thus to counteract the erosion of banks and the transport of rocks, flotsam and drifting objects. This known blocking device is provided with a collecting net acting as a barrier element and forms a flexible blocking system with a large energy absorption capacity, which also keeps itself undamaged when it overflows. [0003] However, if people leave non-empty installations fi...
