1. The development of customized eco-retaining wall
The vegetation holes from the back of eco-retaining wall consists of the absorber layer of water, soil layer and holder layer of vegetation filter. The vegetation holes which the space for revegetation inserted to the vegetation filter. In particular, the vegetation hole will vary to thickness and height of the retaining wall.
When is rain, the seeds or seedlings planted in the vegetation filter is germinate or growth. The techniques of customized eco-retaining wall for carbon dioxide reduction type against climate change has been developed.
The obtained results from this study can be summarized as follows
1) The eco-retaining wall will support and maintain the slope stability to prevent the collapse of the slope, resistance to earth pressure in cutting slope and banking slope. The stability analysis of eco-retaining wall was used the RAD Pro. Manual with dedicated program for the design of the retaining wall.
In the stability analysis of the eco-retaining wall with concrete of 2.5m height, the stability of fall was stabled as 0.145 < 0.375 in ordinary, 0.428 < 0.750 in earthquake. The stability of sliding was stabled as 2.771 > 1.500 in ordinary, 1.822 > 1.200 in earthquake. In addition, the maximum reaction force at all times supportive and earthquake was stabled as 7.628 < 26.479 and 11.420 < 34.420 respectively.
2) Preliminary construction of the eco-retaining wall were allotted in the same area to reduce the experimental error on plant growth by the climate factors. The vegetation holes was composited to 8° in degree and 20 cm in depth using PVC pipe with 100mm diameter. Vegetation holes for planting were placed at the 36 points (3 replications × 3 soil treatment × 4 culture soils = 36) in the form of a zigzag with 50cm in the vertical direction based, 110cm spaced horizontally low. In addition, The main construction in second placed at the 36 points (3 replications × 3 soil treatment × 4 seedlings = 36), vegetation holes were inserted into the vegetation filters.
3) The outside of vegetation filter to prevent the loss of the soil medium and seed for the establishment of vegetation was mulched as jute. The culture soils entering in inside of vegetation filter was created the forest humus soil, merchantable soil, the surface soils of forest and soil mixed with 3 sorts. Culture soil was treated as microorganisms and culture soils with sown seeds or planted seedlings were inserted in the 10 - 30cm deep of vegetation hole on retaining wall.
4) The plants used in the preliminary construction were selected a total of 10 species with native herbaceous of three kinds(Dianthus chinensis, Chrysanthemum zawadskii var. latilobum, Aster koraiensis), traditional woody plant (Lespedeza cyrtobotrya), outpatient herbaceous (warm and cool season grass) of three kinds (Tall fescue, Perennial ryiguass, weeping lovegrass), two kinds of naturalized plants (Chrysanthemum burbankii , Coreopsis tinctoria) and one kind of climbing plant (ivy).
The plants used in the main construction were selected a total of 4 species with native herbaceous of three kinds(Dianthus chinensis, Chrysanthemum zawadskii var. latilobum, Aster yomera) and one kinds of naturalized plants (Chrysanthemum burbankii ).
5) The amount of germination by soil medium after seed highly showed in order of merchantable soil> forest humus soil> mixed soil> surface soil of forest. The germination amount of merchantable soil, forest humus soil and mixed soils in the survey of four times tended to good growth from the beginning of germination, but that of surface soil of forest was lower than other culture soil over time.
6) The merchantable soil and forest humus soil for initial germination were suitable as soil medium. Foreign species( Perennial ryegrass, Tall fescue) and native species(Dianthus chinensis, Chrysanthemum zawadskii var. latilobum) have a good for the effects of early revegetation by seed.
7) The rate of average germination by soil medium was showed in order of merchantable soil(33%) > forest humus soil(19%) > mixed soil(17%) > surface soil of forest (10%), The rate of average germination by microorganisms treatment was observed in order of 50% microorganisms plot(30%) > 50% microorganisms plot(25%)> 0% microorganisms plot (23%).
8) The number of survival populations by soil medium in May were germinated in order of 213 in merchantable soil, 110 in surface soil of forest, in mixed soil, soils, 59 in forest humus soil. The survival rate shows the same trend as that of survival populations. Since May the survival rate of survival populations was reduced in all the culture soil. In addition, the survival rate of surface soil of forest from May to June was abruptly decreased by strongly acidic pH of 3.93. And contents of organic matter analyzed was the lowest in compared to merchantable soil of 61.80% as 2.87%. The available phosphorus needed in the early plant growth was the lowest in compared to that of other cultured soils(merchantable soil: 338.50 ㎎/㎏, mixed soil: 125.04 ㎎/㎏) as 2.53 ㎎/㎏.
9) The changes of population survival by soil medium was higher in order of merchantable soil, mixed soil, forest humus soil and surface soil of forest.
The 50% plot in changes of survival populations by microorganisms treatment was higher in order of merchantable soil, forest humus soil, mixed soil and surface soil of forest. The 100% plot in changes of survival populations by microorganisms treatment was higher in order of merchantable soil, mixed soil, forest humus soil and surface soil of forest.
10) The number of withered populations by soil medium was showed in order of 211 in merchantable soil, 110 in surface soil of forest, 112 in mixed soil, soils, 66 in forest humus soil.
11) The growth of germinated plant by soil medium was showed in order of mixed soil, merchantable soil, forest humus soil, surface soil of forest. The growth of germinated plant by microorganisms treatment was showed in order of 100% plot, 50% plot and untreated plot.
12) The growth of seedlings plant by soil medium was showed in order of forest soil, mixed soil, merchantable soil. The result showed other this the preliminary execution.
13) The growth of seedlings plant Chrysanthemum zawadskii > Aster yomera > Chrysanthemum burbankii > Dianthus chinensis. The mixed soil like as Dianthus chinensis and Aster yomera showed the best growth, The forest soil like as Chrysanthemum burbankii and Chrysanthemum burbankii have a best growth.
14) The foreign species like as Tall fescue and Perennial ryegrass was deemed available for the early recovery of concrete wall showing the status of a good growth in all soil medium. However, if the foreign species planted with other plants, it show a tendency to dominance interferes with the growth of other plants. The native species like as Dianthus chinensis showed the best growth, naturalized plant like as Chrysanthemum burbankii have a good growth.
2. Development of design and construction techniques of eco-retaining walls 1) For the construction of concrete eco-retaining wall, the disaster status and status of weather was conducted in construction area, and surveyed terrain, geological and geotechnical investigation, including soil.
2) The techniques of standards design of concrete eco-retaining wall presented on the design requirements and the basis of safety.
3) The concrete eco-retaining wall constructed the height 2.5m, an area of 30㎡ with one-column configuration in first year. The concrete eco-retaining wall was installed the height 1.0m, an area of 40㎡ with one-column configuration in second year.
4) The causes collapse of the eco-retaining wall like as bearing capacity of foundation soil, drainage hole, compaction of backfill material and concrete strength were investigated in construction area.
5) The functions of eco-retaining wall were presented separately a collapses, air pollution, carbon sequestration, landscape conservation and noise isolation in environmental and public interest.
6) The evaluation of eco-retaining wall relatively conducted for a scouring, settlement status, tilt/turnover states, sliding, and drain state, damage, cracks and wear/erosion. The assessment criteria for stability for eco-retaining wall presented to 5 levels as very good, good, fair, poor and very poor by score.
