Problems solved by technology

[0004] However, in recent years, due to the decline of soil organic matter content, the problems of compaction, acidification, and salinization have become increasingly prominent, and the functions of soil water storage and purification have degraded. Especially in the process of sponge city construction, the soil of urban gardens and green spaces must be greatly improved. To reduce the pressure on the urban drainage system, thereby reducing the occurrence of urban rainstorms and waterlogging

Abstract

The invention discloses a soil percolation agent, particularly relates to a sponge city greenbelt soil percolation agent and a preparation method thereof, and belongs to the technical field of soil improvement. The sponge city greenbelt soil percolation agent is prepared from the following raw materials in parts by volume: 100-150 parts of calcium carbonate, 70-120 parts of phosphogypsum, 4-10 parts of aluminum sulfate, 100-200 parts of furfural residues, 160-280 parts of lignite powder, 150-180 parts of carbonized rice hull powder, 120-180 parts of zeolite powder, 100-150 parts of vermiculite, 20-40 parts of organic materials, 120-190 parts of fine river sand and 20-40 parts of perlite. The prepared soil percolation agent can improve hardened, acidified, salinized and poor-water-seepage-and-water-storage-performance soil, the water storage and purification capacity of greenbelts is effectively improved, the rainwater storage, filtration and purification functions of the greenbelt soilcan be obviously improved, and the soil percolation agent is widely used and can prevent occurrence of urban rainfall flood and waterlogging.

Description

technical field [0001] The invention relates to a soil penetrating agent, in particular to a sponge city green space soil infiltrating agent and a preparation method thereof, belonging to the technical field of soil improvement. Background technique [0002] In recent years, with the rapid advancement of my country's urbanization process, the urbanization rate has reached 59.6% by 2019 and will reach 70% by 2050. Due to the acceleration of urbanization, the urban area is rapidly expanding, and the area of ​​impermeable underlying surfaces such as hardened area and compacted land area is constantly increasing, while the natural water storage area such as green land, depressions, and wetlands disappears in large quantities, making soil infiltration, regulation The storage capacity has been greatly reduced, which has seriously affected the soil's absorption and interception of rainfall, increased the frequency of urban rainstorms and internal waterlogging, and led to increasing...
