Description

Technical Field

[0001] The utility model belongs to the technical field of mine vegetation restoration, and in particular relates to a vegetation restoration device for rock slope convex reverse slope. Background Art

[0002] In mine vegetation restoration, the management of open-pit slopes is a key issue. For revegetation on gentle slopes, spray seeding is the most common and effective technique. For steep slopes, mesh seeding can also be used. The principle is to use galvanized mesh as a support point for the soil, preventing it from collapsing due to its own gravity. However, for slopes with slopes exceeding 80 degrees, or even rocky inverted slopes, mesh seeding cannot effectively stabilize the soil, and the combined use of plant roots and galvanized mesh to stabilize the soil is often difficult to achieve. This has led to the development of various revegetation techniques, primarily for extremely steep slopes, such as troughs, floating platforms, and small-hole planting holes. Troughs and floating platforms primarily use anchor rods to secure external plant growth platforms to the slope, while small-hole planting holes involve regularly drilled holes suitable for plant growth. Both techniques have drawbacks such as large engineering workload and high costs. Furthermore, there is a risk of the troughs and bay windows falling from heights if the supporting steel corrodes or the slope stability is compromised by external forces. Therefore, for high and steep slopes, especially convex slopes, it is very necessary to develop a maintenance-free vegetation device with low cost, simple process, no reliance on manual maintenance, and water storage and water retention functions. Utility Model Content

[0003] The purpose of the utility model is to provide a maintenance-free vegetation device for restoring vegetation on rocky slopes with low cost, simple process, no reliance on manual maintenance, and water storage and water retention functions.

[0004] The purpose of the present invention is achieved in this way, including a flexible backboard, a drainage trough, a vegetation tube, and a water guide pipe. The drainage trough is provided on the upper part of the front of the flexible backboard. The vegetation tube is a semi-cylindrical structure with an open back, the top of the vegetation tube is open, and the bottom of the vegetation tube is an outward convex arc-shaped closed structure. The front of the flexible backboard is fixed with at least two rows of vegetation tubes from top to bottom. The back edge of the vegetation tube is attached to the front of the flexible backboard. Each row has a number of vegetation tubes. The number of vegetation tubes in each row is equal and the vegetation tubes in different rows correspond to each other up and down. Several drainage pipes are provided at the bottom of the flow channel. One drainage pipe extends into the vegetation tube from the top tube opening of a vegetation tube in the uppermost row. Root extension holes are distributed on the corresponding flexible backboards inside the vegetation tubes. A water-retaining support layer and a matrix layer are provided in sequence from bottom to top in the vegetation tubes. A water guide pipe is provided between the upper and lower corresponding vegetation tubes. The upper end of the water guide pipe penetrates the water-retaining support layer of the corresponding vegetation tube from the bottom of the corresponding vegetation tube, and the lower end of the water guide pipe extends into the vegetation tube from the top tube opening of the corresponding vegetation tube. Fixing holes are provided on the surface of the flexible backboard.

[0005] Preferably, the flexible back panel is made of a plastic reinforced plate with a thickness greater than 1 mm, an elongation not greater than 10%, and a tear resistance not less than 300N; the plastic reinforced plate is a material well known to those skilled in the art and has a certain degree of flexibility.

[0006] Among them, the water-retaining support layer is a common filler in this field, which can be volcanic rock particles, perlite, expanded clay and other materials with certain water permeability and water storage capacity. It itself also has the function of supporting the matrix layer. The volcanic rock particles have a porous structure, which makes it have excellent air permeability. At the same time, it will not pulverize, can store water, and its pH value is acidic, which is suitable for the growth needs of most plants. Expanded clay itself is a porous and water-absorbent material. Perlite has low bulk density, strong water absorption, and is easy to drain and ventilate; the matrix layer selects common cultivation matrix.

[0007] As for the fixing holes, they are usually distributed at various positions of the flexible backboard. The number of fixing holes can be flexibly determined according to the size of the flexible backboard. Conventional anchors in this field are used to fix the flexible backboard on the rock slope through the fixing holes. It should be noted that the technical solution of this planting device is not only suitable for rock slope convexity and reverse slope, but can also be used for other steep slopes.

[0008] The material of the planting tube is TPE, TPU or PVC, which has the characteristics of high tension, high durability and high elasticity.

[0009] Preferably, the drainage groove is made of TPE, TPU or PVC, which has the characteristics of high tension, high resistance, high elasticity and the like.

[0010] Preferably, the height of the vegetation tube is not less than 18 cm and the width is not less than 5 cm.

[0011] Preferably, a retaining plate is provided at the outer edge of the top of the vegetation tube. The retaining plate is made of TPE, TPU or PVC, and has the characteristics of high tension, high durability, high elasticity, etc. The height of the retaining plate is not less than 5 cm; the retaining plate is used to retain soil and reduce the loss of slope soil due to gravity and rain erosion; specifically, the retaining plate can also be inclined, and the specific inclination direction and angle are flexibly determined according to the slope conditions, so as to be able to retain soil as much as possible.

[0012] Preferably, the water-retaining support layer and the wall of the vegetation tube are provided with air holes, and the air holes are used for ventilation of the vegetation tube.

[0014] Preferably, the diameter of the root extension hole is not less than 15 mm.

[0016] Beneficial effects of the utility model:

[0017] 1. The flexible backboard of this utility model can be fitted and fixed to the convex reverse slope of rock slope or other steep slopes. Combined with the longitudinal water transmission structure composed of drainage troughs, drainage pipes, and water pipes, as well as the planting structure of the planting tube, a stable plant growth space is established, which helps to improve plant survival rate. Plant roots can pass through the root extension holes to establish a growth space on the slope, gradually forming a growth community in which plants and slopes are integrated, and gradually developing into a more stable and natural plant ecosystem. This utility model effectively avoids the insufficient soil adhesion of traditional hanging net spraying technology, and solves the problems of excessive load and high cost of existing floating platform and planting trough technologies.

[0018] 2. Multiple rows of vegetation tubes can form a large coverage area, increasing the green coverage area; the interior of the vegetation tube is divided into a two-section material layer structure. The upper substrate layer is used to plant plants, and the lower water-retaining support layer not only supports the substrate layer but is also water-permeable. Part of the water is stored in the water-retaining support layer, which is beneficial to improving water retention capacity and reducing the stress of drought on plant growth.
