Slope afforesting construction method

Abstract

The invention provides a slope afforesting construction method using vegetation substrate material added with vegetation substrate water retention material. The water retention material is not easy to run off and can guarantee water retention space and stabilize the afforesting and reinforcement of the slope in the vegetation substrate. And slope collapse does not need to worry in a condition that the slope is very inclined. In the method, vegetation substrate material is spread on the slope 9, thereby forming the vegetation substrate 7. It is characterized in that vegetation substrate material is spread to the slop 9 after applying a simple terrace 8 made from wood to the slope 9 having the vegetation substrate 7. The vegetation substrate material is formed by adding hygroscopic particals having mixed soakage of 3 to 300 ml/g and water into vegetation soil material mixed with water sucking swelling fiber having soakage of 3 to 300 ml/g.

Description

technical field [0001] The invention relates to a slope greening construction method, in particular to a slope greening construction method using a vegetation base material added with a vegetation base water-retaining material. Background technique [0002] At present, it is known that a vegetation base is formed by spraying a vegetation base material mixed with seeds on slopes such as bank revetments, ridges, and reclaimed lands to expect greening and enhanced slope greening. [0003] However, the slope generally has a wide area, and at the same time, the convenience of water use is also poor. Therefore, after the vegetation base is formed, it is difficult to perform regular irrigation, and the moisture required for seed germination and growth depends on rainwater. [0004] However, although the past vegetation base has the effect of preventing loss and certain drying prevention by keeping the seeds through the vegetation base, it has the following problems: its own water r...

[0003] However, the slope generally has a wide area, and at the same time, the convenience of water use is also poor. Therefore, after the vegetation base is formed, it is difficult to perform regular irrigation, and the water required for seed germination and growth depends on rainwater.

[0004] However, although the past vegetation base has the effect of preventing loss and certain drying prevention by keeping the seeds through the vegetation base, it has the following problems: its own water retention is not enough, therefore, in the summer when the sun is strong, etc. When the amount is reduced, or there is a large amount of rainfall at one time but no regular rainfall, which is harsh to plants, it is impossible to promote the germination of seeds and their subsequent growth, thereby realizing the expected greening and strengthening of the vegetation base on the slope. the goal of

[0005] In addition, the conventional vegetation base has the following problems: it is easy to be eroded by rainfall, and the vegetation base is compacted by spraying, so it is difficult to secure a sufficient water retention space inside the vegetation base

[0007] In this slope greening construction method, water-absorbing particles are used as water-retaining materials added to the vegetation base material, but due to rainfall, the constructed vegetation base is eroded, etc., and the water-absorbing particles as water-retaining materials are easily lost. Since it is compacted by spraying, it is difficult to secure sufficient water retention space inside the vegetation base, and the original purpose of the above-mentioned vegetation base cannot be fully realized.

[0008] Moreover, especially in the case of a very inclined slope, the above problems remarkably arise, and there are problems such as erosion of the built vegetation base due to rainfall, collapse of the slope, and need for repair work, etc.
