The invention discloses an external water interception and purification type urban river multi-element ecological embankment physical
structural system. The urban river multi-element ecological embankment physical
structural system comprises a first-class platform ecological embankment physical
structural system, a second-class platform ecological embankment physical structural
system and a slope ecological embankment physical structural
system which are organically combined on a river
bank slope, wherein the first-class platform ecological embankment physical structural
system is provided with an
urban surface source
sewage runoff collecting groove, a groove type ecological concrete building block, a vertical first-class
retaining wall and the like; the second-class platform ecological embankment physical structural system is provided with a
sedimentation and purification tank, a current restriction baffle and the like; and the slope ecological embankment physical structural system is provided with a
bedding, iconological concrete, a
plant growth pad and the like. The urban river multi-element ecological embankment physical structural system effectively integrates
water treatment functions such as rainfall surface source collection and purification,
discharge port
sewage interception and purification, physical absorption and
filtration and
plant absorption and purification on the premise that the stability and safety of
bank slopes are maintained, ecological environments and landscapes of urban riparian zones are improved, and the
self cleaning capacity of rivers is well played.
