FIELD: construction.SUBSTANCE: each prefabricated obstacle structure includes multiple obstacle blocks. Obstacle blocks may include a hollow box-type structural element, a fastening frame from a channel and multiple connection devices, jointly operating to divert water when installed in the riverbed. Multiple connection devices stretch via the hollow box-type structural element for retention of obstacle blocks in the required position. Configuration of prefabricated obstacle structures may be changed, if required, for instance, by increasing wave amplitude, water flow speed, depth measurement, etc. The invention also discloses the method to produce obstacles with alternating configuration, operations of which are disclosed in the invention claims. The method for performance of the prefabricated structure of the obstacle for water passing in the riverbed, consists in the fact that multiple fastening rails are provided from a channel as installed in the riverbed, the first obstacle block is created, containing the above elements, and the first obstacle is fixed in the river bed with the help of the first connection device and multiple fastening rails from a channel, installed in the river bed, compressing at the same time the first hollow box-type structural element. The second obstacle block is created, as stated above. The second obstacle block is fixed to the first obstacle block by the second connection device, compressing at the same time the second hollow box-type structural element. Tension in multiple connection devices and bearing capacity of the hollow box-type structural element resist the pressure force applied by water.EFFECT: system of obstacles has been invented with alternating configuration for a river bed in a river park.14 cl, 31 dwg |
