Embodiment 1

[0039] An installation method using greening structure soil as a rainwater accumulator, comprising the following steps:

[0040] Step A, first design the layout of the structural soil according to the site conditions, the application depth and range of the structural soil, and the requirements for greening and planting, and then dig out all the subsoil of the hard road surface that needs to be greened to form a pit, wherein, The depth and scope of the excavation of the plot are basically the same as the depth and scope of the structure soil to be laid, and the depth is generally slightly higher or equivalent to the municipal drainage pipeline;

[0041] Step B, establishing the position of the planting hole in the pit of step A, and inserting the center point with a straight pipe for future use, the diameter of the planting hole is 1-2m;

[0042]Step C, the establishment of the drainage position, the specific establishment method is: use mortar to fix the drainage pipe device b...

Embodiment 2

[0049] Example 2 Installation of sidewalk structural soil

[0050] 1) Design of structural soil layout

[0051] The designed diameter of the sidewalk planting hole is about 1 m. In order to increase the space for plant growth, prevent pavement from accumulating water, and reduce construction costs, structural soil is only laid 2 m outside the planting hole, and the designed depth is 1.2 m.

[0052] 2) Terrain excavation

[0053] Combined with the road municipal construction, first establish the location of the planting hole, draw a circle with a diameter of 2 m in the center, remove the 1.2 m deep subsoil in the circle with the assistance of an excavator, and reserve a port connected to the municipal drainage pipe.

[0054] 3) Fixed drain pipe interface

[0055] 1 m outside the center of the bottom of the planting hole and close to the municipal drainage pipe, fix the drainage pipe device with four interfaces with mortar, one of the horizontal outlets is about 10 cm long, wr...

Embodiment 3

[0068] Example 3 Installation of structural soil in a small square

[0069] 1) Design of structural soil layout

[0070] The square is located between several high-rise buildings, with an area of ​​about 150m 2 , it is planned to plant 4 large trees on the periphery of the square. In order to increase the space for plant growth and prevent water accumulation on the road, it is planned that the entire square will be covered with structural soil with a depth of 1.5 m. Since the trees are tall trees, the tree hole is designed to have a diameter of 2 m.

[0071] 2) Terrain excavation

[0072] Excavate all the 1.5m deep subsoil within the square area with an excavator, and reserve a port connected to the municipal drainage pipe.

[0073] 3) Fixed drain pipe interface

[0074] Since the entire square is made of structural soil, the design of the drainage pipe can be simplified, and the drainage pipe device with four outlets can only be installed near the municipal drainage pipe....

Abstract

An installing method of a rainwater accumulator for greening structural soil comprises the steps that bottom soil of a land mass of a hard road surface required to be greened is firstly dug away to form pits, then the positions of planting holes are determined, water draining devices are arranged in the pits, and then structural soil and planting soil are laid in a layered mode. The installing method adopts the installing mode that the structural soil and the planting soil are laid in a layered mode, the connecting problem of gaps of the structural soil and the planting soil in the hard road surface is solved, namely the plant planting requirements can be met, the weight bearing requirements of the hard road surface can be also met, timely rainwater permeation can be ensured, a part of rainwater is accumulated in the structural soil, the rest is partially drained to a municipal pipeline in time, impounded surface water is decreased, plant watering times are decreased, and the effect of the rainwater accumulator is played.

Description

technical field [0001] The invention relates to the field of construction, in particular to rainwater accumulation technology, in particular to an installation method for using greening structure soil as a rainwater accumulator. Background technique [0002] With the rapid development of urbanization in our country, urban hard roads have increased dramatically. On the one hand, this kind of hard pavement makes it difficult for atmospheric precipitation to infiltrate into the ground in time, leading to an increase in urban runoff and causing a series of environmental problems such as urban flood disasters after rain. Therefore, how to improve the infiltration rate of hard pavement has become an urgent need in my country's urban development. On the other hand, the sharp increase of urban hard pavement has squeezed the limited green space in the city, and hard pavement such as sidewalks, squares, and parking lots has become an indispensable and important part of urban greening...
