#CMT# #/CMT# The groyne (1) comprises a main body (2) with a slope, the crown of this body being below high tide level but above low tide level, as well as a row of spaced apart flow resistance bodies such as gabions (3). The total height of the groyne is below high tide level. #CMT# : #/CMT# Independent claims are also included for the following: (1) Construction method for the groyne, comprising forming a geotextile-reinforced main body which extends into a body of water from a river bank, cladding the body with a mat of concrete blocks (4) having a low hydraulic roughness, and placing a row of flow resistance bodies on top of the crown of the body; and (2) Gabion for the groyne, preferably provided with a means for fastening it to the groyne body. #CMT#USE : #/CMT# For protecting the bank of a river experiencing high and low tide water levels. #CMT#ADVANTAGE : #/CMT# Silting of the waterway at low tide is reduced, whilst at high tide less turbulence is created so that a good water flow is maintained. The height of the gabions and the distances in between them can be specifically adapted to local conditions. Low hydraulic roughness concrete blocks increases drainage capacity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of the groyne. 1 : Groyne 2 : Main body 3 : Row of gabions 4 : Cladding #CMT#MECHANICAL ENGINEERING : #/CMT# The fastening means comprises a breakable pin. |
