Problems solved by technology

Because the slope surface is affected by natural factors such as ultraviolet rays, sunlight, water erosion, and wind erosion for a long time, it is very easy to weather, peel off, or even collapse the surface mortar, which affects the stability and safety of the slope project. At the same time, cement mortar has a strong absorption capacity. Heat, the heat island effect is obvious, which not only damages the ecological landscape, increases energy consumption, but also goes against the requirements of modern society for environmental protection
[0003] Cement mortar anchor spraying slope greening has always been the focus and difficulty of the industry. Although some technologies are currently in use, due to the constraints of slope site conditions, climate conditions and construction conditions, it is difficult to control the construction quality, and it is even more difficult to meet large-scale projects. Slope greening engineering construction

Embodiment 1

[0028] Carry out afforestation to a cement mortar anchor shotcrete slope with the method of the present invention, specifically as follows:

[0029] (1) Clean up the cement mortar slope surface, remove or reinforce the severely weathered and broken parts of the slope surface, and clean the slope surface.

[0030] (2) Use a rock drill to drill holes on the slope to set root induction holes, with a diameter of 15cm and a depth of 20cm, about 5 holes / m 2 . These root induction holes provide a certain extension space for the plant root system, form a three-dimensional protection, and improve the soil-fixing ability of the plant root system.

[0031] (3) Drill holes on the slope along the contour line with a spacing of 1.5m. The drilling depth is generally 20cm, the hole diameter is 3cm, and the anchor rod with a length of 80cm and a diameter of 15mm is inserted and anchored with cement mortar grouting. Some ecological rods made of PP material, filled with vegetation substrate, a...

Embodiment 2

[0041] (1) Clean up the cement mortar slope surface, remove or reinforce the severely weathered and broken parts of the slope surface, and clean the slope surface.

[0042] (2) Drill holes with a rock drill on the slope to set root induction holes, with a diameter of 20cm, a depth of 40cm, and 7 holes / m 2 . These holes provide a certain extension space for the plant root system, form a three-dimensional protection, and improve the soil-fixing ability of the plant root system.

[0043] (3) Drill holes on the slope along the contour line with a spacing of 3m. The drilling direction is perpendicular to the slope. The drilling depth is generally about 30cm, the hole diameter is about 5cm, and the anchor rod with a length of 50cm and a diameter of 20mm is inserted and cement mortar For grouting and anchoring, an ecological rod with a diameter of 15cm made of PP material is placed above the exposed part of the anchor rod, filled with a vegetation matrix, and the ecological rod is f...

Abstract

The invention discloses a greening method of a cement mortar anchoring and shotcreting side slope, comprising the steps of paving root-system induction holes on the cleaned cement anchoring and shotcreting side slope; setting ecological rods along the contour line; paving and anchoring vegetation cushions, ecological rods and geotechnique grille nets in ecologic rod lattices; and then spraying and sowing vegetation base layers and seed layers, finally covering vegetation blankets. Through the method, the cement mortar anchoring and shotcreting side slope is greened, so that the weathering and stripping of the cement mortar layer exposed in air for a long period can be avoided; the protection effect of the side slope engineering can be enhanced; and the long-time stability and safety of the slope surface can be ensured; meanwhile, the method solves the problem that the artificial planting layer on the cement mortar anchoring and shotcreting slope is eroded by rainfall to slip, fall off and the like, so that the stability of the planting layer can be ensured and a stable base is ecologically provided to the slope vegetation.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and relates to an ecological restoration method for cement mortar anchor spraying slopes. Background technique [0002] In recent years, my country's economy has developed rapidly, and the construction of infrastructure such as roads, railways, water conservancy and municipal services has changed with each passing day. However, during the construction process, a large number of mountains were excavated and quarried, forming many exposed slopes. In order to ensure the stability and safety of slope engineering, the technical measures of slope engineering often used at home and abroad are to spray cement mortar on the excavated slope. support. Because the slope surface is affected by natural factors such as ultraviolet rays, sunlight, water erosion, and wind erosion for a long time, it is very easy to weather, peel off, or even collapse the surface mortar, which affects the stability...
