Embodiment 1
[0022] River ecological pollution type cube frame, such as figure 1 As shown, the prefabricated reinforced concrete bar 1 with a length of 1m, a section size of 0.1 m×0.1m, and a concrete strength of C13-C15 is embedded in each reinforced concrete bar 1 with a length of 1.3 mΦ10 steel bar 2, and the steel bar 2 Concrete rods protrude from both ends.
[0023] like figure 2 As shown, the elastic filter ball 3 is made of materials such as polyethylene and polyolefin plastics. The elastic filter ball 3 is spherical, and the inside of the filter ball is a radial polyethylene filament 4, which has a large specific surface area and is easy to attach and grow a large number of microorganisms. Form biofilm, which can effectively purify water body. The elastic filter ball 3 is connected in series on the lead wire pole to form the elastic filter ball string 6.
[0024] like image 3 As shown, 12 reinforced concrete rods 1 are welded to form a cube-shaped hollow skeleton 7 . Reinfor...

Abstract
The invention discloses a riverway ecological decontaminating type square frame body and a construction, combination and dam fending method thereof. The frame body is formed by assembling a precast reinforced concrete pole and elastic filter ball biological filter. Multiple riverway ecological decontaminating type square frame bodies are overlapped together and fixed in a form of pilling, so that the combination is fixedly placed above a river bed in the direction that the axial line of the combination and the flow line of water form an included angle of 110-120 degrees, and the length of a dam body meets the fact that the ratio of the projected length of the dam body in the direction vertical to the direction of water flow to stable river width is less than 0.3. The frame body disclosed by the invention can be used for stabilizing a bank slope, protecting the river bed, reducing the flow speed and trapping silt, has a better management effect on a high silt-content water body, has a better purification effect on the water body, is favorable for improving the water environment quality, can be used for constructing diversified river bank rest environments, is favorable for repairing an ecological system, is suitable for river realignment of different scales, has lower manufacturing cost, is simple to manufacture, and is relatively convenient to construct, maintain and manage.
Description
technical field [0001] The invention relates to an ecological river engineering structure, in particular to a river ecological pollution-cleaning cube frame with the functions of purifying river water and creating a variety of riverbank biological habitats and a method for constructing a combined dam. Background technique [0002] River structures refer to hydraulic structures built to stabilize or improve river regimes and adjust water flow. Commonly used spur dams, rocky heads, bank revetments, shun dams, lock dams, pile dams, 杩槎 dams, etc. River improvement buildings can be built with river materials such as soil, stone, bamboo, wood, concrete, metal, geotextiles, etc., and can also be built with components made of river materials, such as tip bundles, willow stone pillows, gabions, 杩槎, concrete blocks, etc. . [0003] River structures are generally divided into permeable structures, solid structures and circulation structures. Solid buildings do not allow water to pas...
