Problems solved by technology

[0004] When building a sunken green space, the terrain is generally built first, and then the lawn is laid on the surface of the terrain. This method of construction will easily form an interface between the lawn and the terrain soil because the soil type of the lawn is not necessarily similar to the soil type of the terrain, making the grass It is difficult to adapt and take root in the underground soil, which makes it difficult for the grass to absorb nutrients and water, resulting in a low survival rate of the grass. Therefore, there is still room for improvement

Embodiment 1

[0059] A concave green space construction method based on sponge city, refer to figure 1 , including the following steps:

[0060] S1. Excavate the foundation pit, as follows:

[0061] The foundation pit is excavated according to the design requirements, and the horizontal section size of the foundation pit is consistent with the horizontal section size of the concave green space in the design.

[0062] S2. Lay the substrate, as follows:

[0063] The bottom of the foundation pit is compacted by a road roller to make the bottom of the foundation pit level, and then permeable bricks are laid to form a support layer. At least two layers of permeable bricks are laid, and the level of the top of the support layer starts from the center of the foundation pit and gradually moves toward the edge of the foundation pit. In addition, in this embodiment, the minimum thickness at the midpoint of the support layer is 30 cm, and the maximum thickness at the edge of the support layer is 50 ...

Embodiment 2

[0079] A preparation method of fertilizer granules, comprising the following steps:

[0080] a. Broken, as follows:

[0081] Put the dry animal feces and activated carbon into the grinder and grind them into powder with a particle size of 0.01-0.1mm.

[0082] b. Mix as follows:

[0083] 100kg of dry animal excrement powder, 8kg of calcium peroxide, 23kg of polyvinyl alcohol, 15kg of activated carbon, and 3kg of pineapple leaf fiber were added to the stirring tank, and the rotating speed was 30r / min, and stirred for 5min to form a mixture;

[0084] The length of the pineapple leaf fibers is 2mm.

[0085] Calcium peroxide adopts nano-calcium peroxide.

[0086] c. Press to make granules, as follows:

[0087] The mixture was punched in a granulator to form spherical granules with a particle size of 5 mm to form fertilizer granules.

[0088] d. Dry, as follows:

[0089] The fertilizer granules were laid flat outside for 30 days to fully dry.

Embodiment 3

[0091] A preparation method of fertilizer granules, comprising the following steps:

[0092] a. Broken, as follows:

[0093] Put the dry animal feces and activated carbon into the grinder and grind them into powder with a particle size of 0.01-0.1mm.

[0094] b. Mix as follows:

[0095] 100kg of dry animal excrement powder, 10kg of calcium peroxide, 25kg of polyvinyl alcohol, 16kg of activated carbon, and 4kg of pineapple leaf fiber were added to the stirring tank, and the rotating speed was 30r / min, and stirred for 5min to form a mixture;

[0096] The length of the pineapple leaf fibers is 2mm.

[0097] Calcium peroxide adopts nano-calcium peroxide.

[0098] c. Press to make granules, as follows:

[0099] The mixture was punched in a granulator to form spherical granules with a particle size of 8 mm to form fertilizer granules.

[0100] d. Dry, as follows:

[0101] The fertilizer granules were laid flat outside for 30 days to fully dry.

Abstract

The present invention relates to the technical field of sponge city. Aiming at the problem of low survival rate of green grass, a construction method of sunken green space based on sponge city is provided. The technical scheme is as follows: including the following steps: S1. Excavating foundation pit; S2 .Laying the base material; S3. Laying the base soil; S4. Laying the planting soil: the planting soil is first mixed with fertilizer particles and then laid on the base soil; S5. Laying the surface soil: the top soil is first mixed with grass seeds and then laid on the planting soil; S6 .Prepare the surface of the topsoil; use the same soil for the base soil, planting soil and topsoil. By adding fertilizer particles to the planting soil, the fertilizer content of the planting soil is better. After the seeds germinate, the root system develops into the planting soil to absorb nutrients. It is not easy to form an interface between the base soil, planting soil and surface soil, so that the root system of the grass is easy to penetrate. , thereby ensuring the effect of the grass absorbing nutrients from the planting layer, thereby making the survival rate of the grass higher.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a concave green space construction method based on sponge cities. Background technique [0002] 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". [0003] The concave green space mainly collects rainwater through a large area of ​​grass and temporarily stores it, which acts like a sponge during heavy rain and reduces drainage pressure. [0004] When constructing a concave green space, the terrain is generally constructed first, and then the lawn is laid on the surface of the terrain. This construction method will easily form an interface between the lawn and the terrain soil because the soil type of the lawn is not necessarily similar to the soil ...
