【摘要】：随着人们对传统治水的反思及河道生态环境修复工作开展,河道治理中的生态治理技术逐渐得到发展。结合深圳市葵涌河生态修复工程,基于室内物理模型试验及现场中试试验,就一种典型的复合生物砖护岸结构的抗冲刷能力及生态景观效果进行了总结。利用有压管道产生高速水流,建立了护岸结构冲刷物理模型试验,对复合生物砖护岸结构单元的原体冲刷表明,浸泡12 h冲刷12 h后,生物砖结构不会被完全破坏,形成不超过5.5 cm冲刷坑,抗冲性能良好。复合生物砖护岸结构在深圳市葵涌河现场试验表明营养土可以提高植被的成活率及根系密度。狗牙根草在生长3个月后可以覆盖复合生物砖护岸结构的水泥砖部分并形成良好的景观视觉效果。
[Abstract]:With the introspection of the traditional water control and the restoration of the ecological environment of the river course, the ecological treatment technology in the river treatment has been gradually developed. Based on indoor physical model test and field pilot test, the scour resistance ability and ecological landscape effect of a typical composite biological brick revetment structure are summarized in combination with the ecological restoration project of the Kwai Chung River in Shenzhen City. In this paper, a physical model test of erosion of revetment structure is established by using pressurized pipeline to produce high speed flow. The results of the scouring of the composite biological brick revetment unit show that the biological brick structure will not be completely destroyed after 12 hours of immersion and 12 hours of scouring. No more than 5.5 cm scour pit is formed, and the scour resistance is good. The field test of composite biological brick revetment structure in the Kwai Chung River of Shenzhen City showed that the vegetative survival rate and root density could be improved by the nutritious soil. After 3 months of growth, the grass could cover the cement brick part of the composite biological brick revetment structure and form a good visual effect on the landscape.
