Ecological grass planting trench and application thereof

Abstract

The invention provides an ecological grass planting trench and an application thereof. The bottom (10) of the ecological grass planting trench comprises a vegetation layer (1), a plantation soil layer(2), an anti-seepage layer (3), a gravel layer (4) and a crushed rock layer (5). The ecological grass planting trench also comprises a first trench wall(8) and a second trench wall(9) which are installed at two sides of the trench bottom (10); the first trench wall(8) and the second trench wall(9) are both provided with ecological rods (6), wherein the ecological rod (6) comprises a bag body andplantation soil wrapped by the bag body; the surface of the ecological rod (6) is covered by the vegetation layer (1). The ecological grass planting trench of the invention is provided with the vegetation layer, the planting soil layer, the anti-seepage layer, the gravel layer and the crushed rock layer. Cooperating with the ecological rod stacking ditch wall to adapt to the slope, the fitting degree is high, the adaptability is good, the structure is stable, the water seepage filtering effect is good, the flooding pressure is effectively relieved, and the storage water pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to an ecological grass planting ditch and its application. Background technique [0002] With the rapid development of the national economy and highway construction, people have higher and higher requirements for the quality and level of highway construction. Highways must not only meet the functional requirements of rapid, convenient, and safe transportation, but also integrate and unify with the natural environment of the areas they pass through, complement each other, and complement each other. Therefore, ecological environment construction has become a very important part of highway construction, and an important symbol of highway overall planning and design level and construction quality. Ecological protection technology is the comprehensive use of various ecological measures, biological measures, agronomic measures, and management measures to limit t...

Problems solved by technology

[0005] However, the above schemes are all equipped with permeable pipes, which increases the cost of drainage, and the slope directly covers the vegetation layer, and the adhesion between the vegetation layer and the slope is poor, and the growth of vegetation is limited.

Construction of drainage ditches on slopes, due to the poor stability of the foundation structure, especially on slopes with soil intercalated with rocks or fill accumulations, often when the slope body subsides or partially collapses, the integrity of the ditches will be directly affected, and phenomena such as fractures will occur. Seriously affect the water conduction and drainage functions of the slope during the flood season, leading to collapse disasters on the slope, leaving potential safety hazards
