Abstract
Description
Technical Field
[0001] The utility model relates to a cement frame for slopes, and specifically to a precast cement frame for preventing soil and water loss on the slope surface of granite residual slope soil. Background Art
[0002] With the rapid and efficient development of China's economy, the infrastructure construction projects in the highway field are also increasing continuously. In particular, the scale of mountain expressway construction projects has been expanding year by year. When building expressways in mountainous areas, due to the limitations of terrain, geomorphology and stratigraphic characteristics, etc., it is often necessary to carry out deep cutting and high embankment construction. During the construction of deep cutting and high embankment, based on the principles of excavation and filling balance and ecological environment protection, the waste fill materials generated from deep cutting will be used for filling high embankments. Therefore, a large number of granite residual slope soil slopes will appear after the construction of deep cutting and high embankment along some expressways. In addition, some expressway construction projects are located in the center of heavy rainfall areas, and the rainy season is relatively long throughout the year. In summer, the climate environment with simultaneous rainfall and heat makes the granite residual soil have the phenomenon of dry-wet cycle, resulting in the attenuation of soil strength. At the same time, the continuous rainfall climate makes the shallow soil layer of the granite residual soil slope reach saturation and is accompanied by serious seepage problems, causing further attenuation of soil strength and the formation of through channels. For the structural integrity of the granite residual soil slope, on the one hand, heavy rainfall will erode the shallow soil layer of the slope, causing erosion gullies on the slope and even occurring collapse disasters. On the other hand, the infiltration of rainwater weakens the bonding force of the weak surface of the slope, increasing the risk of slope collapse and landslide. The granite residual slope soil slope faces a relatively large risk of soil and water loss on the slope surface during the construction period and operation period, which will affect the long-term stability of the granite residual slope soil slope, and cause great harm to the rapid and safe construction of expressways and the long-term safe and efficient operation. Some collapses directly erode the forests and cultivated lands at the lower part of the slope surface, resulting in a reduction in the area of forests and cultivated lands. At the same time, a large amount of sediment generated by the collapses will silt up river channels and flood farmlands. The commonly used sand retention dams, three-dimensional net slope protection and cement grid slope protection cannot effectively overcome these problems. Content of the Utility Model
