Description

Roof greening grass planting system adopting building waste

Technical Field

The utility model belongs to the technical field of planting technique. And more particularly, to a roof greening grass planting system using construction waste.

Background

The roof occupies a large space in a city, and with the continuous expansion of the space, the urban heat island effect is increasingly enhanced; the roof is exposed in the atmosphere all the year round, and the heat insulation board is gradually damaged over the long term to form a sanitary dead angle; the temperature difference change of the roof is large, the expansion with heat and the contraction with cold are obvious, and the waterproof layer is easy to age and denature to cause the leakage of the roof. Thus, roof greening has a number of benefits: 1. the urban greening coverage is improved, and the air landscape is created; 2. dust is adsorbed, noise is reduced, and environmental quality is improved; 3. the urban heat island effect is reduced, and the ecological effect is exerted; 4. relieving urban flood and reducing drainage pressure; 5. the roof structure is effectively protected, and the waterproof life is prolonged; 6. the building is kept warm in winter and cool in summer, and the energy consumption is saved. The roof environment is severe, the greening difficulty is high, the greening rate of the roof in China is less than one percent, and the main reason is that the planting technology is not broken through. The invention fundamentally solves the technical problem of roof planting and is expected to make new contribution to roof greening.

The inventor of Hu Li Ming dedicated to the research of roof greening technology for decades, and filed applications from 1998 for 98112641.3 cultivation methods of Sedum lineare for roof greening, 99124618.7 a plant growth nutrition base material and a method for cultivating Sedum lineare on roof, 99322045.2 a nutrition growth bed for cultivating Sedum lineare on roof, 201210048366.7 a greening method for planting Sedum lineare on roof, 201720925170X an isolator for planting Sedum lineare on roof, 201710623907.7 a method for planting Sedum lineare on roof by isolator, and the like, and most of the patents are granted, aiming at achieving the purposes of heat insulation, protection of roof and roof structure through greening. Mr. Hu Li Ming is the earliest to study the sedum lineare roof greening technology and obtain certain effect in China, and most of the current companies which do sedum lineare roof greening in China are the technology of Mr. Hu Li Ming. However, the long-term practice of Huiming has found that the effect of the original scheme is not ideal, problems of clustered sedum lineare, overgrowth of grass seedlings, tenderness and drought resistance can occur, phenomena of withering and poor growth can occur after a period of planting, measures such as reseeding and management are needed, and the sustainability is not strong. The isolation ball planting method solves the problems of clustered sedum lineare, overgrowth, tenderness, drought intolerance and the like, but the isolation balls are made of soil, so that the manufacturing cost is high, and the implementation difficulty is high for large-scale roof greening.

Furthermore, another patent '201820293275.2 applied by the inventor, namely a roof greening structure for planting sedum lineare by adopting construction waste', makes a great progress in comparison with the prior art, adopts the construction waste as a planting base material and combines the use of the seedling control particles to solve part of problems in the sedum lineare planting process, and the patent is also granted. However, the patent mainly aims at the improvement of the sedum lineare planting technology, focuses on the problem of overgrowing of grass seedlings, on one hand, the effect still has great progress space for the requirements of good and continuous growth and the like under the condition of long-term zero management of roof greening, such as the problem of maximum defect root system oxygen deficiency, and on the other hand, the single sedum lineare planting landscape is too single and is not beneficial to the formation of a roof vegetation ecosystem. Meanwhile, with the acceleration of the urbanization process, the problems of construction waste and the treatment pressure are increased year by year.
