Since the 1990 s, the country's investment in infrastructure construction has increased, but the problem of exposed slope surfaces caused by basic projects such as roads, railways, quarries, and dams has become increasingly serious. The exposed slope surface is 0.2 billion to 0.3 billion square meters per year. The speed is increasing. Vegetation destruction, soil erosion and other infrastructure sequelae.Spray machineThe application focus of machinery has shifted from landscaping in the past to the field of ecological restoration.

The traditional protective measures of these slopes are pure engineering measures such as cement and brick, which are not only expensive, but also poor in landscape effect. Spray seeding technology is recognized as a high-efficiency, low-cost vegetation restoration technology for bare slopes in the world. The principle is to adopt the method of planting grass and shrub trees to transform the landscape of the exposed slope. The project cost is about 1/3 of the pure project cost, and it can also reproduce the elegant demeanour of the original vegetation in the area.

At present, the spraying technology has spread all over the country and has been successfully applied in various types of projects. The ecological restoration problem caused by "historical debts" has increasingly become the focus of the application of spraying technology. Sowing machinery and auxiliary materials have been applied to projects such as dust prevention and sand control, vegetation restoration on highway slopes, solidification and vegetation restoration on reservoir collapsed high slopes, and mountain ecological restoration on bare rock and gravel mixed slopes, with good demonstration results.

The goal of vegetation restoration is to reproduce the original appearance of the destroyed vegetation or to rebuild a plant ecosystem that is not identical to the past. The restoration of bare slope vegetation focuses on the restoration of soil function and the diversification of plant environment.

China is a country with complex geology and geomorphology, large span of climatic zone and relatively weak economic foundation, and the exposed slope is serious. And how to adapt to different areas of bare slope vegetation restoration, is the key to the application of spraying machine.

In order to realize the ecological restoration of bare slope, the mechanical structure, geology, climate and other conditions must be taken into account. The slope below 35 degrees is relatively flat and easy to recover naturally, so it is OK to use small spraying machinery. As for the slope above 65 degrees, due to mechanical reasons, it is impossible to rely solely on spraying technology to achieve ecological restoration. The difficulty of achieving ecological restoration with jet sowing technology lies in the 45 ° to 65 ° slope, and the jet sowing machine with high power, large flow, high concentration and high range is more popular.

With the continuous progress of society, people pay more and more attention to the improvement of ecological environment. How to achieve the best ecological effect in the process of spraying and sowing has become the key. In the actual engineering operation, we found that the ecological environment restoration, especially when the highway passes through the mountainous area, should pay attention to appropriately increasing the spraying amount of forest seeds, such as shrubs, trees and wild flower seeds, so as to increase the diversity of species. In the spraying project, Saner Heavy Industry also strives to make the spraying effect as close as possible to and consistent with the original ecological environment before it was destroyed.

Spray technology is widely used in the world. The United States, Japan, Australia and European countries have mature technical equipment, and many have entered our country. However, due to the limitation of the local environment in China, there are few successful construction cases and great limitations. Therefore, in the Chinese market, the proportion of such equipment used abroad is decreasing year by year.

According to China's natural conditions and actual national conditions, Saner Heavy Industry Technology Development Co., Ltd., based on the principles of high efficiency, reliability, economy and application, independently developedGuest soil spraying machineThe 100 percent localization of spraying machines has broken the market pattern of spraying machines dominated by imported products. In the future, Saner heavy Industry will play a more important role in ecological restoration, river slope protection and other ecological treatment projects.
