Description
Technical Field
The invention belongs to the technical field of hydraulic engineering; in particular to a hydraulic engineering flood prevention revetment.
Background
The concave bank of the river bank is washed by water flow year by year, the river bank can be continuously collapsed, the direction of the water flow of the river bank is changed, and then the water flow is continuously impacted and brushed against the river bank, so that farmlands and villages are endangered, a side slope is prevented from being washed, and then a protective building needs to be built on the slope of the concave bank, wherein the protective building is called as a revetment.
Most of traditional revetments collect planting plants, plant roots are used for ensuring that the river bank land is not lost, for example, the invention with the patent number of CN111395259A discloses a flood prevention revetments for hydraulic engineering, which comprises a plurality of gabion cages which are laid side by side and are filled with stones, and also comprises a plurality of cylindrical planting pipes which are spliced with a slope surface, wherein the planting pipes are arranged in a hollow way, the two ends of the planting pipes are communicated, the planting pipes comprise at least two groups of arc plates which are identical in shape and are independent to each other, the arc plates are mutually butted, and the top ends of the arc plates are jointly sleeved with positioning covers for limiting the arc plates; the bottom end of the planting tube penetrates through the bottom surface of the gabion cage, and the top end of the planting tube extends out of the top surface of the gabion cage. Through adopting above-mentioned technical scheme, stretch into the vegetation seedling and plant intraductally and peg graft with domatic, protect the vegetation seedling through the planting pipe, reduce the gravity direct extrusion of stone on the vegetation to improved the survival ability of vegetation on the bank protection, the root system of vegetation extends in domatic earth, improves the ability that bank protection earth resists soil erosion and water loss. Wherein the arc is independent each other, is favorable to providing bigger growth space for the vegetation at the in-process that the vegetation is grown, nevertheless adopts the flood prevention bank protection of this mode, because plant roots carries out the bank protection operation, its root system fixity is limited, and then still can appear the soil loss when the long-time river water that receives of river bank erodees, and then leads to the bank protection to damage.
Compared with the method that the plant root system is utilized to ensure that the land of the river bank is not lost, the prior slope protection adopts the way of building the rubbles, namely, a rubble layer is laid on the slope surface and is formed by piling a plurality of mutually independent gabion cages for containing stones, the gabion cages limit the stones so that the stones are not easy to shift or fall off when water flow scours, and can pile the stones to a higher height, have larger dead weight to compact the river bank, play the role of flood prevention, for example, patent number CN211735263U discloses a flood prevention revetment for hydraulic engineering, which relates to the technical field of hydraulic engineering, and specifically relates to a flood prevention revetment for hydraulic engineering, comprising a slope body, one side of the slope body is fixedly connected with a first step, one side of the slope body is fixedly connected with a second step, one side of the slope body is fixedly connected with a third step, one side of the slope body is fixedly connected with a fourth step, and one sides of the first step, the second step and the third step are fixedly connected with a check net box. The utility model has the advantages that: through the arrangement of the adsorption net, one side of the check-up net box is fixedly connected with the adsorption net, the adsorption net is made of a high-fiber composite material, when the check-up net box is used, dry stones are added into the check-up net box, after water flows through the dry stones, the adsorption net has good adsorbability and water permeability for the high-fiber composite material, silt and suspended particles in water can be adsorbed on the adsorption net and accumulated together to provide space for plant growth, and the purpose of facilitating plant growth is realized, however, the mode can lead the water flow to penetrate through meshes of the check-up net and gaps among the stones to erode soil on a river bank below a gravel layer, and because the gravel layer shields the sunlight of the soil below the gravel layer, vegetation can not grow on the soil below the gravel layer, and further because the root system without vegetation plays a soil-fixing effect on the soil, the soil below the gravel layer is loose, and water and soil are easy to lose after long-term soaking, so that the cavity appears below the crushed stone layer and then collapses.
Meanwhile, the existing slope protection is adopted for flood prevention in a blocking mode, when the water surface of a river is too high, flood discharge cannot be effectively carried out, and then the river dam collapses, and flood occurs.
