Description

Technical Field

[0001] The utility model belongs to the field of ecological restoration of rocky slopes, and specifically relates to an optimized complete set of structures for vegetation planting grooves on steep rocky vertical surfaces. Background Technique

[0002] There are various ecological restoration technologies for rocky slopes. For the vegetation planting groove ecological restoration technology, currently, anchor rods are mostly driven into a stable rock slope at a certain angle and then a scaffolding is erected. A formwork is installed under the steel bar framework, and a cast-in-place planting groove is formed to make it in a "V" shape or "U" shape with the slope surface. The planting groove is sealed with the rock surface, and after backfilling the planting soil, arbors, shrubs, herbs, climbing plants, etc. are planted. This method has a relatively high construction difficulty, large load, is restricted by the terrain, has complex processes, and high cost.

[0003] For some existing improved vegetation planting grooves, ecological bags or geotextiles are placed on the scaffolding to wrap the nutrient soil. When encountering rain, the nutrient soil becomes saturated, and it is easy for the ecological bags (geotextiles) to deform, the ecological bags to be scratched or the geotextiles to spread out. The nutrient soil in the bags or in the geotextiles will cause soil and water loss along the rock wall, resulting in visual pollution and greatly reducing the survival rate of the vegetation. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an optimized complete set of structures for vegetation planting grooves on steep rocky vertical surfaces to solve the problems in the prior art that when ecological bags or geotextiles are placed on the scaffolding to wrap the nutrient soil, when encountering rain, the nutrient soil becomes saturated, it is easy for the ecological bags (geotextiles) to deform, the ecological bags to be scratched or the geotextiles to spread out, and the nutrient soil in the bags or in the geotextiles will cause soil and water loss along the rock wall, etc.

[0005] An optimized complete set of structures for vegetation planting grooves on steep rocky vertical surfaces includes:

[0006] A rock mass with an exposed surface of the rock mass;

[0007] An anchor rod, which is arranged on the exposed surface of the rock mass and partially extends out to form an exposed section of the anchor rod;

[0008] A transverse tension bar, which is welded on the exposed section of the anchor rod to form a steel bar scaffold;

[0009] A U-shaped grass-green PC endurance plate, which is placed on the steel bar scaffold and connected to the steel bar scaffold through a clamp;

[0010] An ecological bag, which is placed inside the U-shaped grass-green PC endurance plate, and nutrient soil is arranged inside the ecological bag;

[0011] Plants cuttaged on the ecological bag.

[0012] Preferably, the anchor rod is composed of 1 φ25mm grade-3 deformed steel bar, and the length extending into the rock mass is determined according to the grade and fragmentation degree of the rock mass, and the exposed length is 0.65m.

[0013] Preferably, the horizontal tie bars are composed of two φ20mm steel bars, with 15cm left on each side, and are welded to the anchor bolts at a spacing of 30cm.

[0014] Preferably, the U-shaped grass green PC endurance board is made of 10mm thick grass green solid endurance board of polycarbonate through bending processing.

[0015] Preferably, drainage holes with a diameter of 5cm are opened on the central axis of the bottom of the U-shaped grass green PC endurance board at equal intervals of 30cm, and the clamps are arranged in two rows at the position of the horizontal tie bars corresponding to the bottom of the endurance board, with a spacing of 50cm.

[0016] Preferably, the plants include Parthenocissus tricuspidata, Euonymus fortunei, and Euonymus kiautschovicus, which are respectively cuttaged at different positions of the ecological bags to form the whole set structure of the vegetation trough.

[0017] Compared with the prior art, the utility model has the following beneficial effects: The U-shaped grass green PC endurance board adopted can provide good physical properties and visual effects, which can not only protect the internal ecological bags and plants from the influence of the external harsh environment (such as strong wind, heavy rain, ultraviolet rays, etc.), but also provide a good growth environment (such as appropriate light transmittance and air permeability), which is beneficial to the growth and reproduction of plants, and can also withstand the impact of falling rocks without being damaged, with good anti-smashing performance and convenient construction;

[0018] By setting drainage holes at equal intervals on the central axis of the bottom of each row of U-shaped grass green PC endurance boards, when the rocky exposed surface is relatively steep, the upper row of U-shaped grass green PC endurance boards receives rainwater over a larger area than the lower row of U-shaped grass green PC endurance boards. In the case of rainwater saturation, the rainwater on the upper row of U-shaped grass green PC endurance boards flows into the lower row of U-shaped grass green PC endurance boards through the drainage holes and is transmitted step by step. When there is too much rainwater, it can be drained to the foot of the slope, enabling the vegetation to absorb more water, which is beneficial to its growth, and at the same time reducing the irrigation frequency and saving costs;

[0019] By placing the ecological bags in the U-shaped grass green PC endurance boards, the contact between the ecological bags and the rocky exposed surface is reduced, that is, the possibility of the ecological bags being cut or scratched by the rock edges and corners of the rocky exposed surface is eliminated, ensuring the integrity of the ecological bags, avoiding the occurrence of soil and water loss signs along the exposed surface due to the damage of the ecological bags, thereby providing a reliable survival soil for the vegetation. At the same time, the base of the ecological bags is a steel bar rack and a U-shaped grass green PC endurance board, which has a reliable bearing capacity and will not deform its base due to the saturation of the nutrient soil in the ecological bags, resulting in soil and water loss.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 4 shown:

[0027] Embodiment 1: The present utility model provides an optimized complete set of structures for a rock steep vertical surface vegetation trough, including:

[0028] Rock mass, having an exposed rock surface 1;

[0029] Anchor bolts 2, arranged on the exposed rock surface 1 and partially extending to form an exposed section 3 of the anchor bolt;

[0030] Horizontal tie bars, welded to the exposed section 3 of the anchor bolt to form a steel bar rack 4;

[0031] U-shaped grass green PC endurance plate 5, placed on the steel bar rack 4 and connected to the steel bar rack 4 through a clamp 6;

[0032] Ecological bag 7, placed in the U-shaped grass green PC endurance plate 5, and nutrient soil is provided in the ecological bag 7;

[0033] Plants 8 cuttaged on the ecological bag 7.

[0034] As can be seen from the above, the exposed surface 1 of the rock mass is the foundation of the vegetation trough, providing the necessary support surface. The anchor rod 2 is anchored into the rock mass to provide strong fixing force, ensuring the stability and safety of the entire vegetation trough structure. The exposed section of the anchor rod provides reliable connection points for subsequent connection and support. The transverse tension bars welded on the exposed section 3 of the anchor rod form a strong steel bar framework 4, which not only enhances the overall strength of the vegetation trough but also provides a platform for installing the U-shaped grass-green PC endurance plate 5. The U-shaped grass-green PC endurance plate 5 is placed on the steel bar framework 4 and is tightly connected to the steel bar framework 4 through the clamp 6. The U-shaped grass-green PC endurance plate 5 can provide good physical properties and visual effects. The clamp 6 is used to firmly fix the U-shaped grass-green PC endurance plate 5 on the steel bar framework 4 to ensure the stability of the system. The ecological bag 7 is placed inside the U-shaped grass-green PC endurance plate 5 and is filled with nutrient soil, providing the substrate and nutrients required for plant growth. The plants 8 cuttaged on the ecological bag 7 are the core components of the entire system. Through growth and reproduction, the plants promote the ecological restoration and landscape beautification of the rock face.

[0035] Example 2: This example is basically the same as the previous example, except that the anchor rod 2 is composed of 1 three-grade threaded steel bar with a diameter of φ25mm. The length extending into the rock mass depends on the grade and fragmentation degree of the rock mass, and the exposed length is 0.65m.

[0036] Specifically, the transverse tension bars are composed of 2 steel bars with a diameter of φ20mm, with 15cm left on each side and welded to the anchor rod 2 at a spacing of 30cm.

[0037] Specifically, the U-shaped grass-green PC endurance plate 5 is formed by bending a 10mm-thick solid grass-green polycarbonate endurance plate.

[0038] Specifically, drainage holes 9 with a diameter of 5cm are opened on the bottom central axis of the U-shaped grass-green PC endurance plate 5 at equal intervals of 30cm. The clamps 6 are arranged in two rows at the corresponding positions of the transverse tension bars at the bottom of the endurance plate, with a spacing of 50cm. Among them, the clamps are arranged in two rows at the corresponding positions of the transverse tension bars at the bottom of the endurance plate, with a spacing of 50cm. Such a setting not only ensures the stability of the U-shaped grass-green PC endurance plate but also facilitates construction and installation.

[0039] Specifically, the plants 8 include Parthenocissus tricuspidata, Euonymus fortunei, and Euonymus kiautschovicus, which are respectively cuttaged at different positions of the ecological bag 7 to form the complete structure of the vegetation trough. Among them, Parthenocissus tricuspidata, Euonymus fortunei, and Euonymus kiautschovicus are cuttaged in the vegetation trough. These plants have different growth habits and ornamental characteristics, and can form a well-proportioned and colorful plant community, effectively improving the ecological restoration effect and landscape value of the rock face.

[0040] As can be seen from the above, the anchor rod is made of grade-3 deformed steel bar with a diameter of φ25mm, which has sufficient strength and toughness to ensure stable fixing force in rock masses of different grades and fragmentation degrees. The length of the anchor rod extending into the rock mass depends on the specific situation, and the exposed length is 0.65m, providing sufficient space for subsequent connection and support; the transverse tension bars are composed of 2 steel bars with a diameter of φ20mm, welded to the anchor rod at a spacing of 30cm, with 15cm reserved on each side. Such a layout not only enhances the overall strength of the steel bar bent frame but also ensures that the U-shaped grass-green PC endurance plate can be placed stably and fixed firmly; it is made of 10mm-thick grass-green solid endurance plate of polycarbonate through bending processing, which not only has good light transmittance, impact resistance and weather resistance but also the color blends with the natural environment, enhancing the overall aesthetics. The drainage holes opened on the bottom central axis can effectively drain the accumulated water, preventing the soil in the ecological bag from being too wet and affecting the growth of plants.
