Abstract
Description
Technical Field
[0001] The invention relates to the technical field of slope construction, and in particular to a spraying system and a construction method for improving the bonding force between a vegetation substrate and a slope surface. Background Art
[0002] Slopes, as the intersection of natural and artificial environments, were originally densely covered with vegetation and had complex ecosystems. However, engineering construction activities frequently destroyed these vegetation, resulting in soil exposure, which in turn caused a series of ecological problems such as soil erosion and soil loss. In order to meet these challenges, ecological restoration technology came into being, aiming to reconstruct or restore the vegetation community on the slope through artificial means to maintain and restore biodiversity.
[0003] Vegetation concrete ecological restoration technology is an effective method for slope ecological restoration. Based on the geographical location of the slope, rock characteristics and other factors, this technology mixes soil, binder, ecological agent and plant seeds in a specific proportion and adds water to form an ecological base material. Subsequently, this ecological base material is sprayed onto the slope surface using professional spraying equipment to achieve ecological restoration.
[0004] The incident speed and angle of the substrate are the key factors affecting the adhesion of the substrate-slope interface. If not handled properly, either the interface adhesion is insufficient, causing the substrate to fall off, or the kinetic energy of the substrate is too large at the moment of spraying, causing it to be bounced off the slope. Therefore, in actual operation, the operator needs to frequently adjust the spray parameters of the spray gun, which undoubtedly increases the difficulty of construction. It is worth noting that most of the widely used spray guns currently spray the substrate at a constant speed, and the spray speed cannot be adjusted in time for different areas of the slope, resulting in large differences in the adhesion of the substrate-slope interface in different areas of the slope, and local peeling and collapse of the substrate are prone to occur in the later stage. In addition, the use of the spray gun also requires the operator to have certain professional skills and experience to ensure the spraying effect and construction quality. However, in actual engineering projects, the skill levels of operators are often uneven, which to a certain extent affects the spraying effect of the vegetation concrete substrate. Summary of the invention

In this spraying system, when the spray gun continuously changes the pitch angle and distance to spray the repair substrate along the slope surface, the spray gun muzzle speed calculation module can automatically retrieve relevant parameters for calculation and match the nozzle speed. Then, the compressor module adjusts the compressor compression strength according to parameters such as the substrate consistency, and finally achieves the optimal slope incident speed to ensure that the substrate strength at different positions on the slope surface is equivalent.
