Description
Technical Field
The utility model relates to a high steep slope ecological remediation technical field especially relates to a suspension type plant and grows device for high steep slope vegetation resumes.
Background
The high-speed development of national economy inevitably needs to increase the construction of infrastructure, the engineering construction of highways, railways, water conservancy and the like and mine mining, and a large number of high and steep slopes are inevitably formed in mountainous areas, the slopes usually have inclination angles of more than 70 degrees and heights of more than 30m, the slope has high rock hardness, low nutrients and poor water retention, plants are difficult to grow and develop, and the original ecological balance is difficult to restore by natural strength. Bare rock slopes can also cause a series of environmental problems, such as atmospheric pollution caused by dust; deterioration of local microclimates (heat island effect in summer); three-area two-line landscape destruction and visual pollution in the visual range. Therefore, technical measures are needed to be taken, under the premise of ensuring the stability of the side slope, the purpose of side slope ecological restoration is achieved by a method for recovering the vegetation of the side slope, the economic development quality is improved, the requirement of the livelihood is improved, and the development concept of 'green water green mountain is the Jinshan Yinshan' is required.
Soil, water and nutrient are basic conditions for plant growth, a good slope vegetation recovery technology needs to have the functions of soil fixation and long-term stable plant growing environment establishment, and water and nutrient are provided for plant growth for a long time through the natural environment, so that the purpose of slope ecological restoration is achieved. If a slope vegetation restoration technology is implemented, the plants and the matrix layer lose vitality without long-term maintenance and irrigation, and the technology cannot be applied to ecological restoration. In addition, the ecological restoration of the side slope mainly depends on the erosion of the leaves, stems and roots of plants to the side slope caused by external force (wind, rain, sunshine, freezing and the like), wherein the roots penetrate into the soil to play a role in soil stabilization and slope protection and are important factors influencing the ecological restoration of the side slope. Because the root system of the herbaceous plant is short and shallow, the soil-fixing effect is poor, the water requirement for growth is high, the capacities of resisting high temperature, sunshine, frost ice and drought are poor, and the maintenance cost is high, the ultimate goal of the slope vegetation restoration is to establish a plant community taking arbors and shrubs as the core. In a word, the establishment of a safe, stable and durable plant growing environment on a high and steep slope is a prerequisite and a key for ecological restoration.
The common technical method applied to the slope vegetation restoration at present comprises the following steps: spraying and seeding the thick-layer plant growth base material; greening method of plant growing bag (ecological bag); a step-type greening method; a floating platform planting groove, a digging planting groove (hole), and the like, or one or more of the technical methods are combined for use.
1. Spraying and seeding method of thick-layer plant growth base material: the technology is an advanced and commonly used slope vegetation recovery technology at present, and comprises the spraying and sowing of foreign soil (hanging net), the spraying and sowing of vegetation concrete (hanging net), a vegetation cell or a three-dimensional grid method and the like. The technology achieves the purpose of constructing the plant growth environment on the side slope by drilling anchor rods to hang grid grids on the side slope and then spraying and sowing the plant growth base material and the grass seed surface layer. There are many patents on the vegetation base material and the preparation method thereof, such as: ZL200510080074.1, ZL200910063087.6, ZL201611086850.3, ZL201810746509.9, and the like. The technology can realize the full soil covering and the full greening of the side slope in a short period, and the early side slope vegetation recovery effect is good, but the technology is only suitable for the condition that the slope of the side slope is relatively slow. The technology has the following defects when being applied to the practice of high and steep slopes:
(1) when the anchor rod is applied to a high and steep slope, although the anchor rod hanging iron wire mesh can be used for supporting the plant growth substrate, the slope surface is usually rugged, so that the substrate at the sunken part is easy to fall off due to the fact that the substrate cannot be supported by the iron wire mesh or the thickness of the substrate is too large;
(2) when the slope is high and steep and is close to vertical and smooth, the anchor rod hanging net supporting structure is not enough to ensure the stability of the soil covering, even if the plant growth base material with strong cohesive force (added with cement or high polymer adhesive material), the plant growth base material and the slope are easy to be collapsed due to the long-term wind blowing, sunshine and rain washing, and the plant growth environment is directly lost. Meanwhile, the easy-to-fall plant growth substrate has greater potential safety hazard;
(3) although a large amount of organic components (humus, organic fertilizer and the like) and loose materials for plant growth are added during the preparation of the base material, because the slope is high and steep, water and nutrients in the natural environment are difficult to be absorbed and utilized by the base material, the water and soil nutrient holding capacity of the base material is poor, and the greening effect in the middle and later stages is difficult to maintain;
(4) in order to ensure the adhesion with the slope, the strength of the base material is higher, so that the germination rate of the plant seeds is low. In order to ensure the early greening effect, the seeds sprayed mainly comprise herbaceous plant seeds. Because the shrub seed content is low, the germination rate is low, and meanwhile, the nutrients required by the shrub growth are further invaded by the fast growth of herbaceous plants, the technology is not beneficial to the growth of the shrub, and is not beneficial to the ecological restoration of the side slope in the long term;
(5) because the thickness of the base material is thin, the sun-proof and high-temperature-resistant capabilities are poor, plants are easy to be dried by the sun and died, and the plants need to be frequently watered and maintained in summer, so that the maintenance cost is high;
(6) in order to ensure the adhesion with the slope, the strength of the base material is higher, so that the germination rate of the plant seeds is low, in order to ensure the greening effect, the seed content per square meter needs to be increased, and the cost of the technology is increased;
(7) the prepared plant growth base material needs to be added with a plurality of chemical components such as a soil conditioner, a greening additive, a water-retaining agent, an adhesive and the like, so that the cost is high; the rebound of the material sprayed on the slope surface is large, the material waste is serious, and the cost of the technology is further increased.
2. Greening method of plant growing bag (ecological bag): the technology is that the geotextile containing seeds and fertilizer is fully attached in a special PVC mesh bag, then planting soil is filled in the bag, and the geotextile is piled on a slope. Because the plant growth bag has large gravity, the method is only suitable for the side slope with small gradient and small height when being used alone for ensuring stability. When the technology is used for a high and steep slope, in order to overcome large overturning force, the anchor rod hanging protective net needs to be constructed by referring to a method of a flexible active protective net of the slope SNS, or the technology is used by combining a reinforced concrete anchor rod frame lattice beam. The construction difficulty is high, the manufacturing cost is high, and the safety is poor, so that the application of the method in the aspect of vegetation recovery of high and steep slopes is limited. The plant growing bag greening technology has the following patents: CN109853593A, CN110042797A, CN103828633B, CN106358639A and the like.
3. Step-type greening method: this is a conventional practice. The method comprises the steps of cutting the original high and steep slope into a plurality of steps with inclination angles not more than 60 degrees, heights not more than 15m and platform widths of about 5m through step-type slope cutting, and planting climbing plants such as parthenocissus tricuspidata and the like on the slope toe to achieve the purpose of recovering the vegetation on the slope. This method has the following disadvantages:
(1) when in slope cutting, a large excavator (with a hydraulic breaking hammer) is required to be used, even blasting is required, the construction difficulty is high, the construction period is long, the cost is high, and the environmental pollution is easily caused;
(2) because the slope of the side slope is slowed down and the platform is added, the range of the side slope is greatly enlarged, the exploitation of soil and stones is greatly increased, and the surrounding environment of the primary side slope is easily damaged;
(3) the height of the cut slope is still higher than 10m, but the growth speed of the parthenocissus altivelis is slow, the survival rate is low, the bare rock slope is difficult to cover in a short time, and the ecological restoration capability of the slope is poor.
4. Greening method of planting groove of floating platform: patent ZL201620568873.7 discloses a sprayed concrete floating platform structure for mine environment recovery treatment, which can construct a safe, stable and durable vegetation environment on a high and steep slope, but the implementation of the design has the following problems and disadvantages:
(1) the slope surface of the side slope is uneven, the steel bars and the templates are difficult to shape, process and produce, and the construction efficiency is low;
(2) the high and steep slope formwork construction difficulty is high, and regular shape and size are not easy to guarantee;
(3) in order to meet the requirements of high-altitude reinforced concrete construction, a scaffold needs to be erected, the slope surface and the slope foot are uneven, the scaffold is difficult to erect, the stability is poor, and the potential safety hazard is large;
(4) the area of the high and steep slope is usually not provided with municipal water and electricity supply, the road and field conditions are poor, the transportation and processing difficulty of materials is high, and the cost is high;
(5) the concrete structure manufacturing materials are heavy, and the materials need to be conveyed to a working surface by means of vertical conveying mechanical equipment such as a crane, and the vertical conveying equipment such as the crane and the like is difficult to reach a construction site due to the limitation of field conditions;
(6) in order to support templates, bind reinforcing steel bars and pour concrete conveniently, the structure size of the floating platform is large, the floating platform looks abrupt on the slope surface, even if the vegetation of the side slope is recovered, the side slope is difficult to be integrated with the surrounding natural environment, the appearance is poor, and the ecological restoration effect is poor.
Disclosure of Invention
