Problems solved by technology

However, due to the limited accumulation of crushed stones and the long transportation distance, the cost of cleaning and transportation is high; the direct covering of soil for planting plants requires a high thickness of the covering soil layer, resulting in a large amount of earthwork, and the source of soil cannot be guaranteed

Embodiment approach

[0089] Plant seeds are selected according to the properties of the base layer 40 or the planting layer 50, local climate conditions, construction conditions and in combination with various plant growth characteristics. As a preferred embodiment of the present invention, the seeds are shrub seeds;

[0090] Preferably, the shrub grass seeds include one or a combination of at least two of amorpha, clover, wattle, tall fescue, horsethorn, dwarf cosmos, magnolia or alfalfa.

[0091] Through the specific limitation of the seed type, it is more suitable for the growth in the base layer 40 and the planting layer 50, and the ideal greening effect can be achieved in a short time.

[0092] As a preferred embodiment of the present invention, the base layer 40 and / or the planting layer 50 are formed by spraying.

[0093] Spray seeding is a new technology suitable for greening of rock-soil slopes with a high degree of weathering and soil interbedded rock slopes. It mainly uses a special sp...

Embodiment 1

[0116] This embodiment provides a vegetation restoration structure on a gravel slope, which includes a covering soil layer, a first protection layer, a base layer and a planting layer arranged sequentially from inside to outside on the gravel slope.

[0117] Among them, the thickness of the covering soil layer is 6cm, and the covering soil layer is mainly made of the following raw materials in parts by weight: 420 parts of loam soil, 45 parts of peat soil, 20 parts of sawdust, 2.0 parts of organic fertilizer and 0.03 part of water-retaining agent.

[0118] The first protective layer is a three-dimensional geonet cushion;

[0119] The thickness of the base layer is 10cm, and the base layer is mainly made of the following raw materials in parts by weight: 350 parts of loam, 1 part of wood fiber, 0.04 part of adhesive, 0.04 part of water-retaining agent, 1.8 parts of compound fertilizer, 0.02 part of microbial fertilizer and water 160 copies;

[0120] The thickness of the planti...

Embodiment 2

[0127] This embodiment provides a structure for restoring vegetation on a gravel slope. This embodiment provides a structure for restoring vegetation on a gravel slope. Protection layer, base layer, planting layer and second protection layer.

[0128] Wherein, the thickness of the covering soil layer is 5 cm, and the covering soil layer is mainly made of the following raw materials in parts by weight: 560 parts of loam soil, 30 parts of peat soil, 35 parts of sawdust, 7.8 parts of organic fertilizer and 0.06 part of water-retaining agent.

[0129] The first protective layer is a three-dimensional geonet cushion;

[0130] The thickness of the base layer is 12cm, and the base layer is mainly made of the following raw materials in parts by weight: 430 parts of loam, 2 parts of wood fiber, 0.06 part of adhesive, 0.06 part of water-retaining agent, 6.0 parts of compound fertilizer, 0.04 part of microbial fertilizer and water 180 copies;

[0131] The thickness of the planting laye...

Abstract

The invention provides a macadam slope vegetation recovery structure and a construction method, and relates to the technical field of slope restoration. According to the macadam slope vegetation recovery structure, by means of matched arrangement of a covering soil layer, a first protection layer, a base layer, a planting layer and other specific structures, the slope stability can be effectivelyenhanced, ecological restoration on a macadam slope is achieved, the needed covering soil is greatly reduced, and the technical problem that the covering soil layer is large in thickness, the soil volume is large, and a soil source cannot be guaranteed due to the fact that direct soil covering is adopted for plant cultivation in the prior art is relieved. In addition, the macadam slope vegetationrecovery structure can control the macadam slope locally, macadam clearing and carrying expenses are saved, the cost is greatly reduced, and the technical problem that due to the fact that in the prior art, a machine is adopted for clearing and carrying the macadam slope in the prior art, the stacking place is limited, the transportation distance is long, and the clearing and carrying cost is highis relieved. The construction method of the macadam slope vegetation recovery structure is further provided.

Description

technical field [0001] The invention relates to the technical field of slope restoration, in particular to a vegetation restoration structure and construction method on a gravel slope surface. Background technique [0002] With the acceleration of urban construction and economic development, people's development and utilization of stone resources have increased significantly. The mining of the quarry has seriously damaged the original vegetation and soil of the mountain, forming a large number of exposed rocky slopes, resulting in fragmented landscapes, intensified soil erosion, loss of ecological functions, and serious damage to the ecological environment. At the same time, due to the unstable structure of the abandoned gravel slopes during the quarrying process, geological disasters such as landslides and collapses may occur, posing a serious threat to the lives and property of residents and the safety of transportation facilities. [0003] In the prior art, machinery is ...
