Gravity type point-adhered rubble stone plant caulking ecological retaining wall and construction method thereof

The invention discloses a gravity type point-adhered rubble stone plant caulking ecological retaining wall and a construction method thereof. The retaining wall comprises compaction pure soil, a concrete cushion and a rubble stone base layer, wherein a trapezoidal wall body is arranged above the rubble stone base layer; the wall body is composed of multiple rubble stone layers and a concrete coping at the upper part; each rubble stone layer is formed by laying multiple blocks of rubble stone through cement mortar; a space between cracks of outer walls of the rubble stone layers on an air face is filled with point-adhered rubble stone or residual soil slurry; cement mortar bricking is carried out between the point-adhered rubble stone and rubble stone; vegetation is uniformly transplanted on the outer wall of cracks of residual soil slurry at intervals; a drainage ditch is formed in the upper end face of the rubble stone base layer; a drainage ditch retaining wall is arranged on the outer side of the drainage ditch. The gravity type point-adhered rubble stone plant caulking ecological retaining wall disclosed by the invention has the advantages as follows: (1), cement dosage is less; (2), the engineering cost is low; (3), plants grow quickly, are attractive and durable, and can absorb heat greatly, reduce the heat island effect, adsorb dust, retain soil and allow water to permeate through; (4), the whole permeability coefficient is high, plenty of moisture can permeate through the wall body while plant roots retain soil; (5), drainage holes are not required to be reserved; (6), the stability is good.
