Description

Ecological landscape protection structure combined with planting concrete and plastic stone on rocky slope

technical field

The utility model relates to an ecological landscape protection structure, in particular to an ecological landscape protection structure combining planting concrete and plastic stone on a rock slope.

Background technique

With the rapid development of high-grade highway construction in our country, especially the advancement of high-grade highway construction to the mountainous and hilly areas in the central and western regions, it is often encountered that mountains and roads are built to form mixed rock and rock-soil slopes. This type of slope is likely to cause a large amount of water and soil erosion. At the same time, exposed rocks will be affected by weathering and rainfall, which will cause rocks to roll and landslides, seriously affecting traffic safety.

Traditional rock and rock-soil mixed slope support usually adopts: retaining wall and face wall, grid slope protection and reinforced concrete shotcrete anchor protection. These traditional forms of slope protection are either poor in durability, low in strength, and poor in integrity, or they have complex construction procedures and high costs. Moreover, these traditional slope protection methods do not start from an ecological point of view, and the vision is blunt and incompatible with the surrounding environment, which does not meet the national energy saving and consumption reduction and the development requirements of ecological highways.

In order to overcome the above-mentioned defects in the prior art, the utility model provides an ecological landscape protection structure combining planting concrete and plastic stone on a rock slope.

In order to achieve the above object, the technical solution of the utility model is:

An ecological landscape protection structure combining planting concrete and plastic stone on a rock slope. The rock slope is provided with anchor rods, integral flexible protective nets, concrete frame beams, planting concrete and planting soil in sequence from the inside to the outside; the anchor rods are implanted Inside the slope, the ends protrude out of the slope as nodes of the concrete sash beams; the concrete sash is composed of vertically and horizontally intersecting beams, and the beams are formed by pouring concrete with steel-plastic grids. Vegetative concrete for plant growth, planting soil is laid on the surface of the planting concrete; the convex part of the stone slope that is not easy to be flattened is treated with plastic stone, and the concave part of the stone slope is made of plastic stone flower pond, and the combination of plastic stone and grass planting forms an ecological environment Landscape protection structure.

For the ecological landscape protection structure, after the slope is cleared, an integral flexible protection net is laid to prevent the soil from sliding downward during the construction of the landscape protection.

The anchor rod is composed of steel bars and mortar, and the steel bars protrude out of the slope as nodes of the concrete sash.

The steel-plastic grid is bound to the end nodes of the anchor rods by tying wires to fix the steel-plastic grid net and prevent the steel-plastic grid from slipping during the construction of landscape protection.

The planting concrete is 50-100mm higher than the upper surface of the concrete sash beam, so that the embedded concrete sash is invisible and makes the protective appearance more natural.

In the ecological landscape protection structure, the concrete sash beams are provided with connecting steel bars for enhancing the connection strength between the concrete sash and the planting concrete

The planting soil contains an adhesive composed of a high molecular polymer, and plant seeds are added in the planting soil so that it can be sprayed on the planting concrete.

The above-mentioned ecological landscape protection structure, before construction, uses plastic stone technology to carry out landscape design on the large and difficult-to-handle protruding stones on the slope to coordinate with the surrounding landscape, forming a combination of plastic stone and grass planting slope protection structure.

The ecological landscape protection structure is provided with drainage ditches at the top of the slope. Before the vegetation grows well and the slope is stable, if heavy rainfall occurs, the drainage ditches can play a role in drainage and prevent accidents such as landslides caused by a large amount of rainwater erosion.

Step 4. Pouring the planting concrete: the planting concrete is poured in the hollow space formed by the concrete sash, and the planting concrete layer is poured by machinery and paved manually, and the planting concrete is controlled to be about 50~100mm higher than the upper surface of the concrete sash beam , so that the concrete sash beams are embedded and invisible;

Step 5. Vegetative soil spraying: After the planting concrete is poured, dry-mix the planting soil containing soil, fertilizer, water-retaining agent, soil improver, binder and water in a mixer, and mix the planting soil before spraying. Mix the seeds in the planting soil and then spray the planting soil with a thickness of about 30mm;

Step 6. Plastic stone sculpture: use plastic stone technology to process the large and difficult-to-handle protruding stones on the slope;

Step 7. Maintenance: Cover and protect the slope planting soil with non-woven fabrics, and use the network sprinkler head to make the curing water into a mist to moisten the planting soil; the wet depth during the germination period should be controlled at 3.5cm, and the maintenance should be performed once in the morning and evening, and the maintenance should be continued The time is not less than 45 days, and insecticides are sprayed every 15 days to prevent plant diseases and insect pests.

The utility model has the following advantages and beneficial effects:

1. This protection requires a small amount of excavation for rocky slopes, which greatly saves the construction period and costs;

2. This protection has little damage to the ecology, and it can also green the slope, which has great social benefits;

3. This protection uses the combination technology of plants and plastic stones, which has a beautiful appearance. It effectively solves the problem of incoordination between traditional protection and the surrounding environment.
