The utility model also discloses an arrangement method of this structure, according to target fingerling spawning time water level characteristic, the subaqueous habitat improvement structure of the prince material is arranged to shallow water district interval in spawning time.
The invention has the following advantages:
(1) is made of natural materials. The manufacturing material is mainly made of wood, stone blocks and hemp rope nets, is natural and environment-friendly, does not release pollutants, and has low cost and wide sources. The wood and hemp rope are degradable materials, and can provide nutrients for decomposers and producers in the ecosystem after degradation.
(2) Adopt the accompanying style triangle timber structure of common racking to deal with the water regime and the river situation change. Duct formula triangle wooden frame sound construction is stable, is difficult for lodging, can resist strong water impact as outside bearing structure, also has higher adaptability to the river trend change.
(3) Bind string bag lump stone, increase structural stability. Tie up at the racking bottom and tie up string pocket piece stone and reduce the focus, increase the whole weight of structure, further promote the equilibrium and the stability of structure. Meanwhile, the string bag block stones have higher void ratio, so that the siltation of silt at the bottom of the structure can be promoted, and the collapse of the structure caused by the fact that water flow elutriates a river bed is avoided.
(4) The special shape is used for creating a suitable habitat. The special structure appearance of the common branch type triangular wooden frame matched with the net bag block stone can change the local flow field of the river, build a slow flow region, enrich hydrological conditions and create a suitable habitat for fishes. Meanwhile, the structure has larger internal space and void ratio, can provide a shelter place for fishes, can also promote silt to silt up, provides a soil matrix for plant growth, and meets the substrate requirements of most fishes for inhabitation and growth.
(5) Filling soil and planting flooding-resistant native vegetation in the middle of the common racking plants. The producers are cultivated by filling soil and planting grass, and the primary production capacity of the ecological system is improved. On one hand, the food net structure can be enriched to provide food sources for fishes, on the other hand, the fry can be kept away and also needs vegetation, and meanwhile, the effect of purifying water quality is also achieved. The vegetation is selected from emergent aquatic plants, submerged plants or other flooding-resistant vegetation, and the native species is preferably considered.
(6) The binding connection mode is adopted, the manufacture is convenient, and the installation and the placement are easy. The common branch type triangular wooden frame and the net bag can be manufactured in advance and then bound and connected to the placing site. The connection of the two adopts the ligature of rope made of hemp, does not need special material and additional auxiliary assembly, and simple to operate is swift, can simplify the construction link, practices thrift the engineering time.
The utility model discloses a racking formula triangular timber frame design: the method comprises the steps of selecting round poplar wood with the length of 2m and the diameter of 15cm as frame rods, binding 6 frame rods together through hemp ropes to manufacture a triangular support with six sides, wherein the binding point is 30-40 cm away from the end of each frame rod, and the diameter of each hemp rope is 1 cm.
The utility model discloses a string bag piece stone structural design: the string bag block stone structure is a regular triangular prism with the bottom side length of 1m and the height of 30cm, the side surface, the bottom surface and the top surface are hemp rope nets with the diameter of 1cm, and the diameter of meshes of the hemp rope nets is not more than 15 cm. The string bag is filled with lump stones, and the grain diameter of the lump stones is 20-30 cm.
The utility model discloses structural installation and placing: before placing, the branch type triangular wooden frame and the hemp rope net bag are prefabricated and molded, block stones are filled in the place of placing, and the block stone net bag is bound to the bottom of the branch type triangular wooden frame by the hemp rope with the diameter of 1 cm. The effect of placing in succession the branch structure is better, and adjacent branch structure interval should be between 0-10 m.
The utility model discloses a place the region: depending on the habitat requirements of the target fish species. Taking the four major Chinese carps in the Yangtze river as an example, the spawning of the four major Chinese carps generally occurs in the water rising process of 5 and 6 months, and after fish eggs are fertilized and developed into young fries, the fish eggs have weak mobility and low survival rate. Therefore, according to the historical water level statistics data, the branch structure is placed in the area which is basically submerged under the water level conditions of 5 months and 6 months, so that places are provided for foraging and risk avoiding of seedlings, and the survival rate is improved.
The utility model discloses a fill up and plant grass: fill soil in string bag piece stone gap, cover one deck soil and suitably compaction at string bag top surface simultaneously, soil layer thickness is about 15cm, ties up the fixed soil of numb rope net in soil layer surface, and the rope net of consolidating soil is unanimous with string bag rope net specification. Sowing grass seeds in the soil layer, wherein the grass seeds can be selected from emergent aquatic plants, submerged plants or other flooding-resistant vegetation in mixed match, and the native species are preferably considered. At least more than three types of vegetation are selected, the number of seeds planted per branch is not less than 100, and the sowing season is preferably 10-11 months. After the first sowing, reseeding is carried out according to the sprouting condition of vegetation in the branches at intervals of 2-3 weeks.
The utility model discloses a maintenance after flood for the first year: after the vegetation is sown, the root system is incompletely developed in the first year, so the soil fertility is poor, and the phenomena of soil matrix loss, vegetation falling and death and the like are easily caused under the water current elutriation. After the first year, proper repair and maintenance are carried out aiming at the conditions of matrix loss, vegetation falling, structural damage and the like.
It should be understood that the above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.
