Description
Technical field
The invention belongs to near-nature forest water resource engineering technical fields, particularly, are related to one kind and are applied to silt content compared with great river
The ecological type of stream moves river sediment trapping weir.
Background technique
In natural ecological environment, due to the interaction of biology and inorganic environment in the ecosystem, lithosphere surface shape
At the loose surface layer-soil for capableing of growing plant.A large amount of microorganisms contained in soil can decompose organic matter, be allowed to become
The inorganic matter that plant can directly utilize;Invertebrate (earthworm etc.) increases interstices of soil, air content by physiological activity
Deng.Therefore, soil is the basis of the important place and most plants growth and development of substance and energy exchange in the ecosystem,
Necessary water, fertilizer, air and heat and mineral element etc. can be provided for plant.
In recent years, with the rapid development of social economy, the soil erosion, soil erosion and ecological degradation etc. lead to river mud
The problems such as husky and graininess pollutant concentration is big, water body self-purification ability declines is increasingly prominent.It is main reason is that surface slope
Greatly, natural causes such as soil property is loose and land use is improper, vegetation deterioration (indiscriminate felling of trees overgrazes), unreasonable ploughs
The human factors such as work.These factors cause Characteristics and Water Conservation Function decline, rainwash to rise suddenly and sharply and break, and in turn result in serious soil
It corrodes and soil erosion, soil and graininess pollutant enters rainwash process therewith.The above problem does not only result in upstream
Nutriment necessary to the plant of domain is lost, but also the silt content in river increases, is in turn resulted in downstream river course siltation, is threatened people
People's property safety.Therefore, how near-nature forest water resource engineering technology is utilized, structure letter is realized in the biggish river of silt content
Single, effective silt intercepts and cleaning, becomes one of the important proposition of river ecosystem restoration and improvement.
Mill weir of crossing in traditional technology mainly passes through water body and retains to raise upstream water level, thus meet field irrigation,
The modes such as the demands such as water project operation, such as Tu Shiyan, steel sheet pile weir, rubber dam.
In recent years, 102234995 B of patent of invention CN, which discloses a kind of armored concrete and constructs the ecology of core-wall, crosses water
Weir, patent of invention 201711116534.0, which discloses a kind of timber+stone, constructs the ecology of core-wall and crosses mill weir, increases some lifes
State element is more in line with the theory and ecological principle of restoration of the ecosystem.But above-mentioned cross at the beginning of mill weir designs not yet considers mud
The function that sand intercepts, applied to then existing in the higher river of sediment content, sediment trapping effect is poor, weir body position is fixed, sediment siltation
The problems such as cleaning difficulty is big afterwards.
Therefore, in order to keep the connectivity and integrality of river ecosystem, river load and graininess pollutant are realized
Effective interception removal, need to develop a kind of ecological type and move river sediment trapping weir, there is particularly important realistic meaning.
