Abstract

The invention discloses a grass cage reinforcement spraying layer ecological slope protection structure comprises a plurality of anchor rods embedded in a side slope, a fixing net is laid along the slope surface of the side slope and fixed on the slope surface of the side slope through anchor nails, a plurality of grass cages are closely laid on the slope surface of the side slope, adjacent grass cages are mutually inserted, the width of each overlapped portion is not smaller than 2 centimeters, a base material layer covers the slope surface of the side slope includes a base layer and a surface layer, the anchor rods and the fixing net are embedded into the base material layer, and parts of grass cages or all grass cages are embedded into the base material layer. The grass cage reinforcement spraying layer ecological slope protection structure and a construction method thereof can solve the problems that spraying layers of steep slopes flow and are difficult to be formed, and the thickness of the spraying layers is difficult to be ensured. Wet spraying layers have good stability, the adhesive rate of base materials is increased, wet-spraying technique is successfully applied to ecological protection engineering of the steep slopes, and efficient and high-quality ecological slope protection is achieved.

Description

technical field [0001] The invention relates to the field of slope ecological protection, in particular to an ecological slope protection structure reinforced with straw cages and a construction method thereof. Background technique [0002] Wet spraying ecological slope protection technology (referred to as wet spraying ecological slope protection technology) uses a high-pressure pump (or at the same time with high-pressure wind) to spray the mixed mud-like ecological substrate onto the slope to achieve the purpose of slope protection and ecological restoration. This technology has a high degree of mechanization and high efficiency. It can complete the injection area of ​​more than 800 square meters per day. There is no dust pollution during construction. It can be used on slopes with large heights and long distances. It has become the mainstream technology for ecological slope protection. [0003] However, when the wet spraying ecological slope protection technology is used...
