The invention discloses a
greening isolation belt construction method based on constructional
engineering. The
greening isolation belt construction method specifically comprises the following steps: installing a
water storage tank, respectively installing isolation water collecting devices on two sides of a main road, connecting an isolation water collecting seat with a water inlet of the
water storage tank by adopting a water collecting
pipe, installing a filtering and
impurity removing device at the upper end of the water collecting
pipe, installing
greening isolation side plates, one side of a
water supply pipe communicates with a water spraying head through a water conveying pipeline on the greening isolation side plates, the other side of the
water supply pipe communicates with a water outlet of the
water storage tank, matching a width limiting supporting plate with an inserting hole in a filtering plate to fix the distance between the two greening isolation side plates, and filling the space between the two greening isolation plates with soil. The greening isolation belt construction method particularly relates to a greening isolation belt, through installation and structural design of a greening isolation device and the isolation
water collection devices, rainwater in a greening belt is collected and filtered, the planting width of the greening isolation belt is adjusted, the adaptability of the greening isolation belt is improved, and the protection on the plants is improved.
