Description

A kind of revetment slope protection module device

technical field

The utility model relates to a revetment slope protection (or called bank protection) module device, which belongs to the technical field of garden and water conservancy.

Background technique

Gardens and other water bodies should have stable and beautiful shorelines, and maintain a certain proportional relationship between the land and the water surface to prevent the water body from being affected by the collapse of the water bank. Therefore, revetments or slope protection should be built at the edge of the water body. The revetment is a retaining wall facing the water, and is a hydraulic structure that supports the land and prevents the collapse of the bank. The revetment is used to maintain the boundary between the land and the water, so that it maintains a certain proportional relationship. A revetment is a retaining wall that is facing water and is used to support the land soil behind the wall. If the water boundary is not treated with revetment, it is easy to collapse the bank wall due to the floating of the water, frost heave or wind and waves, resulting in the retreat of the land, the deformation of the shoreline, and the image of the garden landscape. The revetment can ensure that the bank slope of the water body is not eroded. Usually, the degree of scour on the bank slope of the water body depends on the size of the water surface and the level of the water level. Wind speed and compactness of the shore soil, etc. When these factors reach a certain level, such as the water bank slope without engineering treatment, the bank slope will lose its stability and cause damage. Therefore, the revetment should be designed along the shoreline to ensure that the slope of the water body is not scoured. The revetment can also enhance the landscape level of the shoreline. In addition to supporting and anti-scour, the revetment can also be handled in different forms to increase the changes of the revetment, enrich the façade level of the waterscape, and enhance the artistic effect of the landscape.

With the development of society and economy, people's living standards are improving day by day, and the yearning for a better life is not only material, but the pursuit of spiritual fields is increasing, especially the requirements for the ecological environment are getting higher and higher. Therefore, in environmental construction, people pay special attention to the diversity, safety and viewing of the ecological environment. Water is an indispensable material condition for human survival. In landscape construction, waterscape has become an important aspect to meet people's psychological and practical needs. Therefore, "there is no landscape without water, and there must be water when there is a landscape" has become the practice of creating landscapes. Water features not only add beautiful colors to our living space, but also bring people a comfortable and comfortable mood, creating a beautiful and pleasant water landscape. However, due to the differences in understanding and knowledge, the quality of different forms of waterscape landscapes is uneven, and the most important thing in the construction of waterscape landscapes is the treatment of the form and type of revetment. Only through scientific, reasonable and appropriate shoreline processing methods and methods, can a pleasant hydrophilic space landscape be created. At present, there are two main forms of revetment in garden construction: natural revetment and artificial revetment. Natural revetment is a natural gentle slope formed by turf, stones, plants, etc., various aquatic plants are planted on the water bank, and shrubs and trees are planted on the shoreline to form a hierarchical community and provide a habitat for living creatures. The ecology plays a role in restoration and maintenance, but the overall stability of this kind of revetment is relatively low, and it is greatly affected by the impact of water flow and temperature. The artificial revetment mainly uses reinforced concrete, rock, gabion, concrete, block stone, ecological brick, imitation wood pile and other materials to build the slope. Different materials can be selected according to the basic conditions of the site. Aesthetics. However, this kind of revetment satisfies people's increasing requirement to be close to nature. The surface soil layer is easily eroded by water flow, and it is difficult to intercept and maintain the soil and organic matter entrained by surface runoff.
