Description
Technical field
The utility model belongs to slope treatment field, especially relates to a kind of zoology green-recovery system for flinty slope.
Background technology
Flourish along with China's economic construction, the contradiction of infrastructure construction and environmental protection also becomes increasingly conspicuous.The propelling of urbanization, the construction of hydraulic engineering, the contradiction between the ecological environment of the health that the irreversible ecological disruption adopting traditional handicraft to cause and the people need.Therefore the slope treatment in river course also comes into one's own gradually.
In China, flinty slope zoology green-recovery is operated in each metropolis and starts successively, as Qinhuangdao starts six river ecological riverway transformation pilot projects, Hunhe rigidity revetment zoology green-recovery engineering, although still there is many weak points in the process explored, also achieve good ecological benefits and Landscape benefit.
Traditional water conservancy side slope protection scheme is mainly conceived to the requirement of the function such as flood passage, shipping, the shore protection in river course and lake, slope protection works are mainly considered to safety and the durability of engineering structures, therefore governance model many employings linear pattern shore protection make it channelization, adopts the hardened materials such as stone-laying, concrete or steel concrete.According to incompletely statistics, the current river regulation more than 95% of China have employed flinty slope, in China various places, no matter is river course, reservoir, lake, employs flinty slope all in a large number to ensure the structural safety of side slope.Although mostly consider ecological functions and the landscape need in river course, but because hard material has certain closure, and people is for giving a farfetched interpretation obviously, therefore affect with the large multipair environment of method of hard material structure vegetation, and extremely inharmonious with natural environment, the sight of environment is had a greatly reduced quality.
At present, two aspects are below mainly contained for the restoration of the ecosystem of flinty slope both at home and abroad:
1, carry out restoration of the ecosystem after abolishing flinty slope, namely abolish hard domatic after, then restoration of the ecosystem is carried out to bank protection.But this methods engineering cost is too large, at some city river because soil factor cannot be implemented, so this kind of method is not suitable for spread.
2, on flinty slope basis, carry out restoration of the ecosystem for directly carrying out restoration of the ecosystem on rigidity revetment, research both domestic and external is not a lot, and some technology are ripe not enough, need to be further improved, and concrete implementation result is also barely satisfactory.
Flinty slope has many weak points, and first flinty slope is non-ecological revetment, and bank protection is hardened, underground water exchanges and is blocked, soil crested, plant loses the bedding of growth, and microorganism exchanges and is blocked, behind slope, soil is easily downright bad, losing plant causes ecological chain to rupture, and the self-purification function of river is lost, and shore protection is hardened stereotyped, flinty slope surface is without greening, and landscape effect is poor.
Secondly, poor durability, flinty slope to the bad adaptability of channel distortion on a small scale, run into poor soil property, depression, expansive soil, dyke subside, the uplift pressure of freeze protuberance or water time easily there is local failure or structural instability; Once there is local failure in rigidity lining, because roomy broken plate is easy to be removed under the impact and buoyancy of current, occurrence of large-area is destroyed, and causes the acceleration water erosion of base soil;
Again; easy generation entirety is destroyed; the bad hydraulic permeability of flinty slope; when river surface SEA LEVEL VARIATION is larger; because the seepage velocity of rigid facing is slow, mask very easily floats by larger hydrostatic pressure, causes mask entirety to destroy; various mask mode of failure, in the protection of reservoir area mask in the past, often occurs during when water level spy falls.
Finally, overall cost and maintenance cost high, material usage is large, the manpower of at substantial, once it is very inconvenient and costly, usually require more regular structural decking that its patch work occurs to destroy, random poor.
