Transferred by categories: green roof is an international trend, the developed countries in the forefront. Such as green roofs in Germany have more than one million square meters, they seemed to use economic means to the implementation of imperative green roof, a green roof you do, the Government to provide financial perquisite to 50 euros a square, you do not have lines, but I'm apologetic, along to the roof area of the metropolis drainage facilities charge fares. Recently, more accent on our servant, such as Beijing, Chengdu, Shanghai and other areas. Overall, however, the implementation of the administration or invalid, thunder, little rain.
Green roofs do pay attention to what?
First of all, the maximum major green roof or should appliance the Subordinate to the landscape ecological benefits of efficiency!
Second, we must first consider the safety of green roofs, primarily the old roof, security has two aspects: the security of loads, (including live load and dead load), load insufficient to do the roof garden, can do simple green roofs, straw, or drought-resistant plants. Loading how to count? Plus everything the roof, where the proportion of soil water in part to calculate. Another security What is it? Is leak-proof water design! No matter that there are not roof waterproofing layer, waterproof layer must take into account the existing and additional reinforcement of a waterproof layer! There is a mentioning in Guangzhou, In truth, destroyed the roof is not green, what is it? Done a long time afterward the watery green below the affect of small cracks in the native roof and small defects are exposed and have been enhanced!
This is easy to do in the 90 pilot green roofs, the soil layer thickness ranging from 2 to 10 cm.
the pearly part is wrapped waterproof test, the red is stocked goldfish!
Third, the so-called green roofs I have more than 20 recipes to be a test matrix, found in natural soil moisture condition, the weight of the different matrix formulations are significantly different, but the water had saturated, this difference can virtually be ignored! Why? Because the breach is water! This is what I said in the above soil part of the load measurement to count to the proportion of water, an important cause! (Load calculation must be considered when massive rain had saturated the weight of the water!) Therefore, the so-called matrix formula can not fair consider the light, but from nutrition, physical and chemical properties, durability, fixed capability and sustainability of root so considered. Special can not be also light, easy to decay organic matter may not be too much, should be controlled at 15 ~ 20%!
This is what we had to do matrix formulation experiment.
This is our annual in Guangzhou urban districts do amplify the trial.
Fourth, it is required to consider the drainage, but also consider the water! A good design should make full use of green roof stormwater retention.
Fifth, whether it is the roof garden, to factory trees and shrubs, then, to consider the wind planting chart!
Well, winded a few, do not overwhelm the. Please enjoy the original bar. (Zhang Qiaosong 2010-07-25)
Roof landscape (including the green roof,
GHD Hair Straightener, sky garden) construction, with the increasing urban density and building the multi-layered and there is the development of urban green space to the three-dimensional and amplify green space, multi-dimensional expansion of urban greening and beautifying the natural factors of a fashion.
a roof construction of the meaning of landscape
significance lies in its purpose: to create a more innovative public space, increase urban natural factors, the green coverage, landscaping, to defend and improve the urban environment, improve the urban ecosystem, and enhance urban economic, social and environmental sustainable development. Meanwhile, the roof garden to refine people's emotion and build a good image of the city.
Second, the roof of the elementary principles of landscape design
financial landscape roof construction techniques and green landscaping as an, highlight the pulchritude of aesthetic conception. Important method of smart use of the main roofs of architectures, platforms, balconies, bay windows and garden walls and additional open space, full use of garden plants, micro-topography, water gardening and garden ornaments and additional factors, the use at King, group scene, point outlook, landscape gardening techniques such as barrier, creating different functions and nature of the landscape.
the basic principles of its design is:
1. frugal and practical: a reasonable economic use of urban space environment, is forever the city planners, builders, managers pursue. In appending to the roof garden to meet the different method requirements, should be mainly green plants to build a broad scope of environmental air and eminent changing the layout of the new park Lin Xiaojing, to eco-efficiency, environmental and economic benefits of the composition.
2. Safety Science: The conveyor is building the roof altitude garden, we must consider the building itself and the safety of workers, including structural load-bearing building and the secure use of the roof waterproofing, and protective railings roof 4 weeks of security. Separated deserving to the earth, the ecological environment has changed, to meet the plant growth light, heat, water, air, nutrients and other needs, we must accept new technologies, the use of new materials.
3. exquisite beauty: flowers chosen with the analogy, meaning linked to the same period passing, the main landscape, building chips such as situation and scale, should be considered carefully, both to the main buildings and coordinated the circling context, but also a unique new garden manner. Not only in design, but also in construction management and cautious culling of substances should be everywhere. Should also be on the grass by the junction and placed in various locations scattered high and low personal garden bulbs, not only from the lighting effects,
GHD Red Butterfly 2011, but also as a jewelry join beauty and savor.
4. Note systematic: Planning must be systematic, to overcome the arbitrariness, the use of garden alternative is no simply to watch, to simulate natural. Choice garden plants resistance, taint and cloud pollution of muscular, easy to plant and cozy living and easy management and protection. Configured because either stratified prototype to amend the foliage area concordance, to ensure tall environmental benefits.
3 garden design
pretended mounds, ponds, pavilions, corridors,
GHD Green Butterfly 2011, although an important part of the roof in the Landscape, but the trees and flowers should be the theme for the landscape, all kinds of trees, flowers, lawns, the proportion should be 50 % to 70%. Plant Landscaping in the form commonly used in the design are the following:
1. planting trees and shrubs in the bundle, unique plant: plant small trees and ornamental shrubs, vine wood, garden masterpiece is not merely the bones, merely too to improve the wind quality of the protagonist. Therefore, trees and shrubs should be the main body of the roof garden, the planting in the form to disburse consideration to clump planted, effectively solitary plant, and the world garden accent Zhi Cong is the variety of trees and shrubs ambition be planted together, and the height of different trees dispersed through the merge, the use of its morphology and seasonal changes, the formation of varied fashion, expression of a mood, such as magnolia and crape myrtle the cluster planting and so ashore. Sucked agreeable lone ornamental plants and a smart gesture, and color is wonderful long flowering small trees, such as Begonia, bloom, etc., personally planted in people's eyes are condensed.
2. bloom beds, flower bed design: micro-topography in a growing area of freedom, building flower beds, flower bed. Flower beds with square, circular, rectangular, diamond, plum-shaped, etc., can be accustomed alone or in a perennial bandage, can also be used in groups??? Combined type. Used by plants to keep the sunny colors and clean contour. Multi-use plants cheap, compact plant type, flowering fruitful, wealthy color, long flowering species such as Primula, pansy, zinnia, salvia, marigold, Calendula, Begonia, Tulip , hyacinth, Petunia and so on. The flower bed is to flowers planted in the roof on the plane of the base, similar to the flower beds but smaller. Flower bed can also be sorted into a
3. flower boundary and lawn: the woods, hedge, wall or building sketches for the background of the strip of natural-style floral configuration. Flower diameter of the edge of the roof of the environment according to the different segments, can be a natural curve, you can also use a straight line, and a variety of configurations is a natural mixed flowers. Not divide into a King lawn planting, but to
4. Note with King: In addition to the main scene outdoor with flower boils, flower barrels, green dotted line dispelled essay surrounding area or along the roof of the building layout, boost the atmosphere and landscape, it should be In the winding paths, lawn corners and higher plants, the display 1-2 specific shape of stones, so as to reflect the hardness and softness of the content, receive a rich landscape effect.
Fourth, several technical problems to solve
roof garden landscape is a special form, which is based on top of the building platform as the basis, the water, cover soil and create a green space landscape beautification form. Therefore, the roof garden design and construction, the emulating appearances should also solve the special technical problems:
1. depress the load problem: is a weigh of load per element area on the roof to withstand the weight of the index for building safety and protection of the success of the roof garden. The roof garden landscaping for the overall placement should be used or prefabricated strengthened concrete roof for the structure layer, conditions are, absorbent material can be made of impermeable insulation Under normal circumstances, necessitate 350 kg / m taxed load of more than ability. At the same time the specific design, in addition to considering the roof dead load, we must also consider the non-fixed facilities, the digit of personnel mobility, plus the forces of nature and other factors. In order to reduce the load, should Pavilion, ##############, flower beds, ponds, rockeries and other smudges larger weight bearing structure design in a smaller place or a span, and as we select man-made soil,
GHD IV Dark Straighteners, peat mire, humus and other light materials.
2. waterproofing and drainage systems: load-bearing requirements are met, the plenary roof should be leak-proof manipulation, the waterproof layer composite waterproofing treatment facilities should be used, that set the waterproof coating layer and the reinforcement waterproof layer of fine aggregate concrete strict two lines of barricade. Application of waterproof coating layer non-woven fabric to make a second or two cloth six Tu Tu, on this foundation do rigid waterproof layer,
GHD MK4 Gold Straighteners, strict waterproof layer and a roof flashing must be made to ensure its water quality. Construction of waterproof layer after coating, but also to behaviour a water test. Meanwhile, in the implementation of the construction of roof gardens, no matter what the facilities are not open or harm to the roof of the waterproof layer or protective layer. Then set the faultless drainage system is, in addition to the flood hole, gutter, we must also set the outlet, such as drainage channels, tempest drainage and while to meet the annual needs of torrent, and to do regular washing, thinning Amoy go.
3. Path Construction: path of the design is also profitable learning, generally 50-70 cm wide path, the path winding throughout the roof will be divided into several patches of different sizes. Path of the subgrade can be 6 cm wide bricks, mystery each 1.5 meters to remain affixed to the drainage aisle dark, dark chasm 7-8 cm wide. As the foundation with cement mortar, cobblestone paving the roadbed, so the path was simple flavor. In addition, some roof fell into the water pipes,
GHD Hair, drainage pipes and garden atmosphere, quite uncoordinated, rockery can hide their package, it can also be sculptural techniques such as implicit coated molded trunk.
green roof garden is to hasten the development of the city, promoting urban environmental protection an important course. We should be technological, reasonable, standardized urban roof garden construction, improve the quality of urban landscaping and improve the living environment and beautify their homes for the behalf of everybody.
