Shape Stabilized flood Protection Wall Segment

Abstract

The flood protection wall's shape stabilized segment affords an increased level of protection and is made up of a water fillable bag whose shape, when full, is defined by the plane of the base and the dome-shaped casing with a convex surface that is attached to the base by two plane faces. It is characterized by the fact that the complex convex casing surface ( 1 ) consists of three basic convex areas—front foot area ( 2 ), central blocking area ( 3 ) and rear foot area ( 4 ). In the casing's design, the front foot area ( 2 ) and rear foot area ( 4 ) are connected by straight lines to the central blocking area ( 3 ). In the direction of these lines, there is a front partition ( 5 ) connected to the inside wall of the bag's casing ( 1 ) and a rear partition ( 6 ) connecting the casing ( 1 ) with the base ( 7 ) in such a way that the upper edges of front and rear partitions ( 5, 6 ) are at the same stabilizing height (v′) with respect to the base ( 7 ) and their lower edges are connected to the inside wall of the base ( 7 ) at the point where the width (s) of the base ( 7 ) is divided into two unequal parts. At this point, the front partition ( 5 ) forms an angle (a) of 70 to 90° with the rear partition ( 6 ). The casing ( 1 ) is equipped with at least one filling channel ( 8 ), at least one air channel ( 9 ) and at least one exhaust channel ( 10 ).

1 . The flood protection wall's shape stabilized segment affords an increased level of protection and is made up of a water fillable bag whose shape, when full, is defined by the plane of the base and the dome-shaped casing with a convex surface that is attached to the base by two plane faces, characterized by that the complex convex casing surface ( 1 ) consists of three basic convex areas—front foot area ( 2 ), central blocking area ( 3 ) and rear foot area ( 4 ), the front foot area ( 2 ) and rear foot area ( 4 ) are in the casing's design connected by straight lines to the central blocking area ( 3 ); in the direction of these lines, there is a front partition ( 5 ) connected to the inside wall of the bag's casing ( 1 ) and a rear partition ( 6 ) connecting the casing ( 1 ) with the base ( 7 ) in such a way that the upper edges of front and rear partitions ( 5 ,  6 ) are at the same stabilizing height (v′) with respect to the base ( 7 ); this height is 0.6 to 0.8 times the entire height (v) of the casing's design ( 1 ); their lower edges are connected to the inside wall of the base ( 7 ) at the point where the width (s) of the base ( 7 ) is divided into two unequal parts; the section adjacent to the front foot area ( 2 ) is larger than the section adjacent to the rear foot area ( 4 ); the front partition ( 5 ) forms an angle (a) of 70 to 90° with the rear partition ( 6 ); furthermore, at least one filling channel ( 8 ) and one air channel ( 9 ) is formed in the central blocking area ( 3 ) of the casing ( 1 ), and moreover, the rear foot area is equipped with at least one exhaust channel ( 10 ). 
   
   
       2 . The flood protection wall's shape stabilized segment according to  claim 1 , characterized by that the upper part of the central blocking area ( 3 ) of the casing ( 1 ) has a canopied area ( 3 ′) as opposed to the remaining side parts ( 3 ″) of the central blocking area ( 3 ), which are separated by a canopied partition ( 11 ) that is placed horizontally in the same way as the central partition ( 12 ) connecting the upper edge of the front and rear partitions ( 5 ,  6 ), and lying at a height (v′), which is 0.6 to 0.8 times the entire height (v) of the casing's design ( 1 ). 
   
   
       3 . The flood protection wall's shape stabilized segment according to  claim 1 , characterized by that the ratio of the height (v) of the casing ( 1 ) to the width (s) of the base ( 7 ), which ranges from 1:2 to 3:4.
