Flood-preventing revetment for water conservancy project

Abstract

The invention relates to a flood-preventing revetment for a water conservancy project. The revetment comprises a plurality of parallelly paved gabion cages filled with stones and further comprises a plurality of cylindrical planting pipes inserted into a slope surface. The planting pipes are hollow and penetrate at two ends. Each planting pipe comprises at least two groups of arc-shaped plates which are same in shape and independent to each other, the arc-shaped plates lean against each other, and a positioning cover for limiting the arc-shaped plates is connected jointly to the top ends of the arc-shaped plates in a sleeving manner. The bottom ends of the planting pipes penetrate the bottom surfaces of the gabion cages, and the top ends of the planting pipes extent outside the top surfaces of the gabion cages. By adopting the technical scheme, vegetation seedlings stretch into the planting pipes and are inserted into the slope surface, so that the vegetation seedlings are protected bymeans of the planting pipes and the condition that gravity of the stones extrude the vegetation directly is reduced, and therefore, root systems of the vegetation elongate in muddy soil of the slopesurface, o that the ability of the muddy soil of the slope surface to resist water and soil loss is improved. The arc-shaped plates are independent to each other, so that a larger growth space is provided to vegetation in the vegetation growing process favorably.

Description

technical field [0001] The invention relates to the technical field of water conservancy projects, in particular to a flood control slope protection for water conservancy projects. Background technique [0002] Flood control slope protection refers to the general term for various paving and planting on the slope surface to prevent the slope from being scoured. The concave bank of the river bank is washed by the water year by year, or soaked by the high water level in the flood season, which will cause the river bank to collapse continuously. In order to protect the safety of bridges and embankments, protection must be built on concave banks. [0003] In existing water conservancy projects, in order to reduce soil erosion on the slope, a gravel layer is generally laid on the slope. The existing gravel layer is generally formed by stacking stones in a number of independent gabion cages. The stones are limited so that the stones are not easy to shift or fall off when the wate...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: although the gabion cage filled with stones has a large self-weight, it can also limit the stones, but the water flow can penetrate the mesh of the gabion cage and the gap between the stones to erode The soil on the river bank below the crushed stone layer, and because the crushed stone layer blocks the sunlight of the soil below, the vegetation cannot grow on the soil below the crushed stone layer, and because there is no root system of the vegetation to fix the soil, the soil below the crushed stone layer The soil is loose, and it is easy to lose water and soil under long-term immersion, causing a cavity under the gravel layer to collapse, so there is room for improvement
