Description

A greening structure on both sides of the street that takes into account both drainage and road guidance

technical field

The invention belongs to the field of sponge cities, and in particular relates to a greening structure on both sides of a street that takes into account both drainage and road guidance.

Background technique

Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a "water elastic city".

The international term is "low-impact development of rainwater system construction", which absorbs water, stores water, seeps water, and purifies water when it rains, releases and utilizes the stored water when needed, and realizes the free migration of rainwater in the city.

Starting from ecosystem services, combining multiple types of specific technologies to build water ecological infrastructure across scales is the core of sponge cities.

Under the new situation, sponge city is an innovative expression of promoting green building construction, low-carbon city development, and smart city formation. After the "sponge city" material is applied to the urban landscape pavement, it exhibits excellent water seepage, compression resistance, wear resistance, slip resistance, environmental protection, beauty, color, comfort, easy maintenance, sound absorption and noise reduction. Effectively alleviate the urban heat island effect, so that the urban road surface is no longer hot.

The green structures on both sides of the street are simply ground cover, shrubs or trees, lacking the ability to absorb, store and drain water.

As shown in Figures 1-5, this embodiment provides a greening structure on both sides of the street that takes into account both drainage and road guidance. The greening structure includes: a sidewalk 1; The sidewalk 1 near the main body 2 forms a curved surface inclined to the concave main body 2, an arbor planting pit 3 is arranged inside the concave main body 2, a coaming plate 4 is arranged on the upper part of the planting pit, and the interior of the concave main body 2 and the coaming plate 4 are arranged There is a permeable pavement 5; and a drainage pipe, the water inlet of the drainage pipe is arranged at the bottom of the concave main body 2, and the water outlet of the drainage pipe is connected with the urban drainage system. The so-called enclosure 4 is a rectangular structure with holes reserved in the middle, and is made of non-permeable materials. The enclosure plate 4 effectively prevents soil erosion in the planting pit from causing pollution, and also enlarges the standing surface.

The side of the concave body 2 is placed against the street, and the pavement of the sidewalk 1 is lower as it is closer to the street.

Permeable pavement is laid on sidewalk 1.

A water diversion channel is provided on the sidewalk 1 , and the diversion channel is communicated with the concave main body 2 .

The material of the permeable pavement 5 is cobblestone or permeable asphalt or permeable concrete.

The materials of permeable pavement 5 are permeable bricks and cobblestones.

A number of soil planting areas 7 are arranged in the middle of the permeable pavement 5, and the thickness of the soil planting area 7 is equal to that of the permeable pavement 5, and is used for planting green plants.

A passage area 8 for pedestrians is left between the planting areas 7 . The number of arbor planting pits 3 is 2, which are symmetrically distributed in the concave main body 2. A first soil planting area 7 is arranged in the middle of the arbor planting hole 3, and a T-shaped second soil planting area 7 is also included. A passage area 8 is left between one side and the first planting area 7, and the other side of the T-shape is arranged along the side close to the street. Such an arrangement not only has a good viewing experience, but also facilitates subsequent maintenance. And the green plants on the T-shaped side form a better street outline, giving the vehicle a better guiding effect.

The inner side and bottom of the concave body 2 are provided with a water-impermeable cement layer 9 .

The water inlet of the drain pipe is square, and a cover plate 10 is arranged on the water inlet. One side of the cover plate 10 is hinged to one side of the water inlet through a torsion spring, and the other three sides of the water inlet are provided with elastic sealing rings 11, which are recessed into the main body. 2. When there is no water inside, the other three sides of the cover plate 10 are arranged on the elastic sealing ring 11. When the water in the recessed body 2 reaches a predetermined percentage, the cover plate 10 is turned over to be below the elastic sealing ring 11. The scheduled percentage is 70-80%

Limiting rings are set on the other three sides of the water inlet on the elastic sealing ring 11 . When there is no water inside the concave body 2 , the other three sides of the cover plate 10 are arranged between the elastic sealing ring 11 and the limiting ring.

A construction method for a greening structure, the construction method comprising the steps of: making a sidewalk foundation inclined to a street pavement; making the concave main body on the sidewalk foundation, and digging a planting pit in the concave main body; A cement layer is laid in the inner surface of the concave main body (excluding the planting pit), a drainage pipe is arranged at the bottom of the concave main body, and the drainage pipe is connected with the urban drainage system; trees are planted in the planting pit; the rest in the concave main body Permeable pavement is arranged in the space, and a first pit and a second pit are reserved on the upper surface of the permeable pavement; the first pit is filled with a planting soil layer; the planting soil layer is implanted Ground cover and/or shrubs; hoarding is laid in said second pit.

By constructing a concave main body, the unity of trees, ground cover and shrubs is realized, and the ornamental value is improved; through the structural design of the concave main body and the sidewalk, the rainwater in rainy weather can be effectively discharged into the concave main body from the sidewalk, ensuring the sidewalk. It also effectively collects the rainfall on the sidewalk; through the design of the drain pipe in the concave main body, when the water pressure in the concave main body is small, water retention can be achieved, and when the water pressure in the concave main body is large, the drainage can be realized. The problem of balance between drainage and water retention is well solved; by setting the permeable pavement and cement layer, a water-holding chamber is constructed, and the permeable pavement also acts as an effective support for the upper hoarding and green areas; The passage area is convenient for personnel activities; through the mixed permeable structure of permeable bricks and cobblestones, the overall structure of the permeable pavement is kept stable and the drainage holes are prevented from being blocked.

Although the above embodiments have specifically described the present invention, it should be understood by those skilled in the art that modifications or improvements can be made based on the disclosure of the present invention without departing from the spirit and scope of the present invention. and modifications are within the spirit and scope of the present invention.
