Flood irrigation net type composite protective structure and method for applying same to ecologically protecting high and steep side slope

Abstract

The invention discloses a flood irrigation net type composite protective structure which comprises a plurality of anchor rods, an inner-layer net and a wave type outer-layer net. The anchor rods which are uniformly arranged are buried in a side slope, the inner-layer net is parallelly laid along a slope surface of the side slope, the wave type outer-layer net is laid on the upper side of the inner-layer net, a planting substrate layer covers a double-layer type composite plant growing net formed by the inner-layer net and the wave type outer-layer net, a wetting belt net is laid on an outer layer of the double-layer type composite plant growing net, plant growing nets are laid on the wetting belt net at intervals of certain distances, and spaces between the plant growing nets and the wetting belt net are filled with anti-scour water retention layers; water delivery wetting tubular belts are woven to form a net of the wetting belt net. The invention further provides a method for applying the flood irrigation net type composite protective structure to ecologically protecting the high and steep side slope. The flood irrigation net type composite protective structure and the method have the advantages that the problem of poor stability of substrates used in spray seeding technologies for greening side slopes at present and incapability of utilizing the substrates to ecologically protecting existing high and steep side slopes can be solved by the aid of the flood irrigation net type composite protective structure and the method; the substrate layer holding capacity of the slope surface can be enhanced, and the stability of the planting substrate layer can be greatly improved; water can be automatically supplied to greening plants on the side slope by means of flood irrigation in a balanced manner, and accordingly water and energy can be saved.

Description

technical field [0001] The invention relates to the field of slope ecological protection, in particular to a submerged net-type composite protection structure and a method for ecological protection of high and steep slopes. Background technique [0002] The construction of highways, railways, hydropower stations and other projects will inevitably cause damage to the surrounding environment, and the formation of a large number of exposed soil slopes and rocky slopes will lead to soil erosion and ecological environment imbalance. Ecological greening can protect the stability of cuttings, maintain water and soil, improve the ecological environment, and enhance the landscape effect, so the method of ecological greening on slopes has a positive effect on engineering construction; [0003] High and steep slopes (slopes with a height greater than 30 meters and a slope of 45-85 degrees) generally have the characteristics of no soil and poor soil quality. The stability of the materi...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a kind of submerged net-type composite protection structure and its method for ecological protection of high and steep slopes, which can solve the poor stability of the base material in the current spraying technology used in slope greening , The problem that it cannot be used for the ecological protection of high and steep slopes increases the ability to hold the base material layer on the slope surface, greatly improves the stability of the planting base material layer, and at the same time can automatically and evenly soak the green plants on the slope; Simple operation, low cost, water saving and energy saving
