Problems solved by technology

Traditional artificial islands use sand, gravel and soil as the base, requiring large-scale construction equipment. The construction process is complicated, and construction in inland rivers is inconvenient; small floating ecological islands are often used in small and medium-sized rivers in cities. Limited coverage area, low purification efficiency in open water, not suitable for open water

Abstract

The invention provides an artificial ecological island capable of being rapidly assembled for a medium-sized open water area and a construction method of the artificial ecological island. The tail endof a steel cylinder assembly is inserted into the water bottom riverbed, a reinforced concrete cylinder is installed on the steel cylinder assembly, and the steel cylinder assembly is filled with steel cylinder filler; the top end of the steel cylinder filler is covered with water-impermeable non-woven fabric used for preventing erosion and loss of the steel cylinder filler, a hollowed-out section is formed in the middle of the reinforced concrete cylinder, and reinforcing ribs for reinforcing the strength of the hollowed-out section are arranged on the hollowed-out section; and the reinforced concrete cylinder is sequentially filled with two-piece stone, block stone, broken stone, a water-permeable geosynthetic material, medium coarse sand and tillage planting soil from bottom to top, and the block stone section and the broken stone section are located in the hollowed-out section. The ecological island can provide a medium for water purification of the water body and break through the height limit of an inland waterway, the use of large hoisting equipment is avoided, and the artificial ecological island is quickly and safely constructed.

Description

technical field [0001] The invention relates to the technical field of water environment ecological management, and more specifically relates to a rapidly assembled artificial ecological island suitable for medium-sized open waters and a construction method thereof. Background technique [0002] After the water body is polluted, its self-purification ability is poor, which can easily lead to eutrophication of the water body, resulting in the lack of oxygen in the water body and black odor. As my country's economy enters a stage of high-quality development, water environment governance has attracted more and more attention from the society. [0003] The artificial ecological island can provide suitable growth conditions for various aquatic plants and improve the purification ability of the water body itself. Traditional artificial islands use sand, gravel and soil as the base, requiring large-scale construction equipment. The construction process is complicated, and construc...
