Embodiment

[0024] figure 1 It is a cross-sectional view of the combined slope protection structure of palm fiber and silica powder of the present invention.

[0025] figure 2 for figure 1 top view.

[0026] Such as figure 1 and figure 2 Shown, the combined slope protection structure of palm fiber and nano-silica powder of the present embodiment, it comprises palm fiber 1, nano-silica powder 2 and filling soil evenly mixed, honeycomb porous barbed wire 4 and a plurality of steel rope buckles 5. The honeycomb porous barbed wire 4 used for slope protection is laid on the surface of the planting soil layer, the honeycomb porous barbed wire 4 is fixedly connected with the slope surface through the steel rope buckle 5, and the honeycomb porous barbed wire 4 is provided with a net for plants to grow through. hole.

[0027] The palm fiber 1, the nano-silica powder 2 and the filling soil are evenly mixed, and the honeycomb porous slope protection barbed wire 4 is spread on the surface of...

Abstract

The invention provides a palm fiber and silicon dioxide powder combined slope protection structure. The palm fiber and silicon dioxide powder combined slope protection structure is characterized by comprising a revetment, a slope protection iron wire net horizontally and uniformly laid on the revetment, and a plurality of steel rope buckles, wherein one ends of the steel rope buckles are connected with the slope protection iron wire net, and the other ends of the steel rope buckles are fixedly connected with the slope surface of the revetment; and the revetment comprises a slope body formed by laying palm fibers, filling soil and nano silicon dioxide powder, and a plantation soil layer laid on the slope body. Each palm fiber is cylindrical, but the surface of each palm fiber is obviously uneven and rough and has short tomenta and certain grooves, mechanical interlocking force between the palm fiber and the soil can be remarkably increased through the surface, and friction between the palm fibers and the soil is increased, so that the revetment is more stable. The palm fiber and silicon dioxide powder combined slope protection structure is easy and convenient to construct, small in workload and efficient, and saves energy. Green vegetation is planted through the slope protective iron wire net, a landscape can be beautified, landslide can further be avoided, and the slope protection structure has great significance for slope protection construction and ecological civilization construction.

Description

technical field [0001] The invention relates to a slope protection and bank protection structure device, in particular to a slope protection structure combined with palm fiber and nano silicon dioxide powder. Background technique [0002] Subgrade slopes and river bank slopes are important components of road engineering construction. If they are not handled properly, the slopes are prone to chipping, collapse, and landslides, which will not only damage driving safety, affect the normal operation of the road, but also damage the environment, and even cause major economic losses. loss. In order to ensure the stability of the road slope and prevent the slope from collapsing, collapsing or landslide, it is necessary to take reasonable engineering measures, such as building gravity retaining walls, sheet pile retaining walls, or slope protection. In the design, practical, reasonable, economical and beautiful engineering measures should be selected to ensure the safety and stabil...
