mattress can be divided into monolithic mattress, biplate mattress and
foot mattress, etc, and there are also various types of soft mattress
with and without fillings, which are separately covered to riverbed or
bank slope surface where washing may probably occur, thus riverbed or
bank slope soil mass is separated from water floe to avoid washing.
Place riprap, precasted concrete block or interlocking blocks in soft
mattress as pressure weight, to protect soft mattress from being floated
up or moves by water flow.Visit us:
