Embodiment 1

[0034] Embodiment one, Project cavern greening project:

[0035] The slope of this project is a concrete shotcrete anchor slope. The upper part of the slope is soil, with an excavation slope of about 45o, and the lower part is hard rock, with a slope of about 65o. The average thickness of the concrete on the surface of the slope is about 15cm, and the area is about 2900m 2 , good vegetation around the slope. Adopt the following methods for greening construction.

[0036] (1) Slope surface treatment: Remove dangerous stones, pine stones, pumice stones, floating roots, herbaceous plants and garbage on the slope surface that hinder the attachment of soil cultivation within 1 meter of the junction with the spray anchor slope surface.

[0037] (2) Setting of vegetation holes: Drill vegetation holes on the concrete surface, the diameter of the vegetation holes is 15-30cm, the depth is subject to passing through the concrete layer, the number density is 2-3 per square meter, and t...

Embodiment 2

[0049] Location: Exit of Tunnel No. 1, Nangou, Lanshang Expressway, Shaanxi Province, with a project area of ​​3500m 2 , slope 60 o , Construction started in June 2009.

[0050] The construction method is as follows:

[0051] (1) Slope surface treatment: Remove dangerous stones, pine stones, pumice stones, floating roots, herbaceous plants and garbage on the slope surface that hinder the attachment of soil cultivation within 1 meter of the junction with the spray anchor slope surface.

[0052] (2) Vegetation hole setting: Drill vegetation holes on the concrete surface, the diameter of the vegetation holes is 15-30cm, the depth is subject to passing through the concrete layer, and the number density is 2-3 / m 2 , Vegetative hole spacing is 65-75cm. The plant holes are filled with common local planting soil and added with 1.2% compound fertilizer, and compacted.

[0053] (3) Planting blanket laying: The planting blanket is laid from top to bottom to ensure that the sewing thr...

Abstract

The invention discloses a spraying and sowing greening method for a concrete anchoring and shotcreting slope. The spraying and sowing greening method comprises the following steps of: (1) treating a slope surface; (2) excavating plant-growing holes and filling soil for planting; (2) paving plant-growing blankets on the concrete anchoring and shotcreting slope surface from top to bottom; (3) laying metal gauzes on the plant-growing blankets from top to bottom, and anchoring the metal gauzes by using anchoring parts; (5) preparing a spraying and sowing substrate material which is a muddy material containing plant seeds and has the flowability; (6) spraying and sowing: spraying and sowing on the spraying and sowing substrate material on the slope surface by adopting a spraying and sowing device, wherein the spraying and sowing substrate material can be used for making artificial soil with good stability in an instant; and (7) maintaining and managing. The spraying and sowing greening method is used for carrying out spraying and sowing greening on various type of slopes with gradients of less than or equal to 750 under the condition of keeping the integral structure of the anchoring and shotcreting slope surface stable, wherein the various types of slopes are subjected to concrete anchoring and shotcreting support, thereby forming a plant community which combines arbors, shrubs and grasses, is enduring and stable, and harmonious and consistent with ambient ecological environments and enabling the hard concrete slope surface to be greened and beautified forever.

Description

technical field [0001] The invention relates to the field of slope ecological vegetation restoration, in particular to a method for spraying greening on a concrete anchor sprayed slope hardened and protected by a physical method. The invention is also applicable to various rock slopes, especially slope vegetation restoration with high steepness, small rock gaps and extremely harsh site conditions. Background technique [0002] At present, with the rapid development of our country's economy, the infrastructure construction is advancing by leaps and bounds, and various types of excavation and filling slopes have appeared. In order to ensure the safety and stability of the slope and prevent soil erosion, physical protection, ecological protection and physical protection and ecological protection are mainly used. A combination of the three methods. [0003] As a physical protection method, concrete anchor shotcrete protection can effectively prevent geological disasters such as...
