Abstract

The invention discloses an ecological percolating type water purification groin system, which has a trapezoidal structure. A biological strengthening purification area is formed in the middle of the system, and block stone is arranged on the two sides; a mixture of sand, broken stone and soil is arranged between the steel mesh cobble stone and the block stone; submerged plants and planting bags are arranged on the outer surface of the block stone, emergent aquatic plants are arranged on the top, and a broken stone hardcore bed is arranged at the bottom; a cobble filtering body is arranged on the broken stone hardcore bed; the surface layer of the biological strengthening purification area is a reinforcing dam top; and the two sides of the reinforcing dam top are provided with stone steps. The invention has the advantages that: relatively good water purification effect is realized; the purification body can realize batch production in plants; and the pollutants in the water flow and the pollutants adsorbed on the gravel surface are absorbed and decomposed through the joint effect of the plant root system and a microbial film. The block stone can prevent the water flow from eroding the groin foundation and enhance the stability of the side slope and the resistance against storms; and the submerged plants in the stone area can purify the water in rivers and provide a good habitat for the growth of the aquatic plants in rivers, while appearing as a landscape.

Description

technical field [0001] The invention relates to an environment-protecting hydraulic structure, in particular to an ecological percolation type water-purifying groyne system with effects of water quality purification and shore protection. Background technique [0002] Spur dikes are hydraulic structures widely used in river regulation and protection projects. The main function of traditional spur dikes is to protect the river bank from scouring damage caused by water erosion, and to adjust the river flow structure to protect the stability of the bank slope. With the deteriorating quality of the river water environment and the increasing requirements for water quality improvement, river structures need to be developed in an ecological direction, that is, river structures are used for bank protection, waterway improvement, water retention and interception, sediment retention, river stabilization, and emergency rescue. While blocking the mouth, it also has the functions of impro...
