Description
Technical Field
The invention relates to the technical field of building construction, in particular to a sidewalk structure for urban natural turf and a construction method thereof.
Background
The sidewalk is one of important components in urban roads, and along with the rapid development of cities, the sidewalk is not a special passage for pedestrians to pass through in use, is endowed with a new connotation in the development of the cities, and plays an important role in dredging urban traffic, building urban landscapes, utilizing underground spaces and depending on urban public facilities.
At present, common sidewalk paving materials in cities are divided into three main categories: stone materials, paving bricks and concrete. In recent years, the earth climate becomes warmer and warmer due to a large amount of activities of human beings, and in addition, the population of cities is concentrated, the high buildings are erected, and asphalt and concrete pavements are densely distributed, so that a stone city with a heat island effect is formed, all large and medium-sized cities in China enter hot summer too early, inconvenience in work and life is brought to residents in the cities, a large amount of energy is consumed, and the environment is polluted. In order to change the environment, besides the limited green parks and lakes in the city, the sidewalks, the street and the square occupying nearly one fourth of the ground of the city become facilities which can be directly used by any resident in the city to feel the environment.
At present, in public parks and squares in cities, artificial material lawns and plastic grass planting grid natural lawns are adopted. The former seems green environment from the color and walking feeling, in fact, because the material adopts a large amount of chemical synthetic materials, the temperature, humidity and air quality of the material are not improved, and the pollution to the environment is increased from another angle. The other method of the plastic grass planting lattice natural turf improves the environmental temperature, humidity and air quality relative to the first method, but because the plastic grass planting lattice is paved by adopting a small-block splicing structure, the substrate of the plastic grass planting lattice is the gravel soil to meet the load of pedestrians and vehicles, so that the situation that a small amount of planting soil and grass can only be placed in the small grass planting lattice is determined, the planting soil and the grass planted between the lattices are separated, and in addition, a part of load is born by the planting soil and the grass when a person treads the lawn by a vehicle, so that the soil is hardened, the survival rate and the durability of the natural turf are greatly reduced, the maintenance and renovation cost are higher, the greening effect in the later period is greatly reduced, the greening effect of the grass planting bricks is poorer, so the method is only used in partial parks and squares at present, and the popularization effect is not great.
