How do the old roof garden waterproofing (1) Old building flat roof waterproofing flat roofs if the original construction is used in rigid waterproof practice, before rebuilding the roof garden, you should thoroughly check and repair surface cracks and split ointment. After the repair of the roofs of the best closed water test, the roof is filled with 100mm deep water drain after blocking Yan, until 24 hours after the check for leakage. (2) Old Building Flat roof drainage roof garden of all kinds of plant roots and leaves are easily clogged roof drains, so the roof garden of the sewer outfall should be increased and increased diameter. If you increase the diameter of the outlet and increase the difficulty, we should try to improve the outfall structure, so that it can quickly discharge roof water. The most important thing is to promptly clean up the debris of roots and leaves of plants, it does not flow into the pipe. In the planting soil planting area must be placed drainage layer and a filter layer, both to plant roots aeration, but also play a filtering effect. Planting soil in the fine particles easily flow into the sewer, serious cases can clog water pipes, roof design, roof caused water to become leaky roof problems. (3) properly handle garden ornaments and landscape architecture with the old roof slab structure links built roof garden, roof garden design engineering, pillars and floor structure has a strong link, in order to prevent the roof wind landscape architecture and pieces blown, garden pillar architecture and sketches must be fixed and firm, but also the need of embedded iron in the floor. Embedded parts must be through the roof waterproof layer exposed roof when wearing waterproof layer must ensure that there is proper construction practices. Although in recent years the construction of a roof garden to get a certain amount of development, however, found that a large number of green roofs after the completion of the course, there are many problems, which are embodied in government and administrative departments concerned enough, technology promotion detrimental, costly and old ideas. (1) regional development imbalance due to an imbalance of more than 600 cities, urban infrastructure and geographical differences in economic development, there is a big difference. Green roofs stage mainly in big cities and economically developed regions to carry out, even in the same city, the new city and the old town can be green roof conditions there is a big gap. Many cities in greening or blank. (2) The Government is not enough attention to the main directions of the government is currently working on urban greening limited ground greening, roof garden design case, some cities in the absence of available green land is transferred to the transformation of the old parkland, on the roof Green's role can not be understood by considering the difficulties of too much green roof, roof garden design, and therefore less investment in research, experiment, technology promotion, lack of special management of construction enterprises. In the current social management, the government's guidance and promote tend to have less effective, the development status of Chengdu green roof fully illustrates this reality.
