<p>#CMT# #/CMT# The mattress has a layer made of a geological substrate and provided between outer layers, which are made of geo-plastic. An upper layer has a rough three dimensional structure such as wire of non-plastic filaments. An outer side of an upper barrier layer exhibits a spatial structure and a high-low structure in a type of hump or combs. The geological substrate is made of gravel, stones and bricks and displaced with a biogenic material such as dead wood, bark pieces, cones, moss and part of clay pellet. The mattress is divided into longitudinal compartments (1). #CMT# : #/CMT# An independent claim is also included for a method for horizontal filling of an erosion protection mattress. #CMT#USE : #/CMT# Mattress for protecting erosion in river bed below water structure or bridge and flood water flow. #CMT#ADVANTAGE : #/CMT# The design of the mattress ensures natural migration of insects and erosion protection for the river bed below the bridge, flood water flow, small and middle running waters in ecologically compatible manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of an erosion protection mattress with complements. 1 : Longitudinal compartments 2 : Front bar 3 : Broad side bar 4 : Rear fastening bar 5 : Narrow side bar 6 : Flat bar.</p> |
