Description
Technical Field
The utility model relates to an ecological protection structure suitable for a high slope in loess areas, and belongs to the field of ecological environment protection.
Background
The slope protection engineering is an important safety measure for preventing the slope from landslide and slumping, and can effectively reduce the loss to personnel, engineering and economy. Traditional slope protection engineering often aims at the slope with lower slope height and slower gradient, and for loess slopes, large-area bare soil can obviously reduce the reinforcement effect of plant roots on soil, and the steep slope body can also aggravate the erosion of rainwater, causes serious soil erosion problem, and the soil eroded by rain erosion can not only influence the slope esthetic, can also very big influence slope stability, brings the hidden danger for the safe operation of highway.
In addition, traditional concrete bank protection form is single, to the side slope that needs large tracts of land to carry out slope protection, pours a large amount of concrete and can seriously increase the side slope dead weight, reduces the side slope stability coefficient, increases the side slope unstability probability, if the slope protection takes place the fracture, can aggravate the rainwater infiltration more, seriously endanger side slope safety. Therefore, for the high and steep slope in loess areas, a slope protection form suitable for the ecological protection structure of the high and steep slope in loess areas is needed, so that the slope can be prevented from being washed by rain, excessive rainfall permeated by soil can be timely discharged, water and soil loss is reduced, the natural ecological environment in loess areas is maintained, meanwhile, the slope stability requirement can be met, and the dead weight of the slope can be excessively increased on the premise of protecting the slope in a large area.
The ecological slope protection is a slope protection technology for reinforcing a slope or a slope by using plants to form a comprehensive slope protection system consisting of plants or engineering and plants. Common ecological slope protection forms are: grass planting protection; paving turf; soil-alien plant slope protection; grass planting and slope protection by a slurry rubble skeleton, etc.
Grass planting protection is to loess area, because grass seeds are easily washed away by rainwater, reason such as grass planting survival rate is low often does not reach satisfied side slope protection effect, moreover appears domatic ditch, surface soil loss etc. side slope disease easily, leads to a large amount of side slope disease renovation and repair engineering.
The newly paved turf is easy to receive various natural disasters due to difficult early maintenance management, and a satisfactory slope protection effect is often not achieved, so that slope disasters such as slope ditches, surface soil loss, slumping and sliding are caused, and a large number of slope diseases are cured and repaired. In addition, the transportation, maintenance and construction of turf have a great influence on engineering economy.
The slope protection of the soil-alien plant is required to be gentle, and the convenience and the economical efficiency of construction of the slope with larger slope gradient can be influenced to a certain extent. In addition, the foreign soil and loess cannot be stably and firmly combined.
Conventional grass planting revetments with a grout sheet stone framework tend to expose a large amount of soil, and for high and steep slopes, the rain wash of the slope is often aggravated, so that a large amount of water and soil loss is caused. If a large amount of poured concrete is used, cracks are often formed at the toe of the slope without adopting reinforcing measures, so that infiltration of rainfall is aggravated, the stability of the whole slope is influenced, and the slope is caused to collapse and damage.
The utility model provides an ecological protection structure suitable for loess area high side slope solves the problem that loess area high steep side slope faced, guarantees the domatic protection plant survival rate of loess area high steep side slope, reduces soil erosion and water loss, improves the soil and water stability of loess side slope, reduces the quantity of concrete simultaneously, reduces economic cost, guarantees that the domatic protection of large tracts of land can not excessively increase the side slope dead weight and influence the stability of side slope.
