Problems solved by technology

Common aquifers are mostly filled with natural stones, and natural stones have a low water storage capacity, generally 0.2-0.25t / m 3 , on the other hand, the bulk density is high, the construction is difficult, and the mining of natural stones is easy to damage the natural environment and cause unnecessary pollution

Abstract

The invention relates to an artificial water storage stone and a preparation method thereof. The water storage stone includes a permeable layer and one or more water storage chambers located in the water permeable layer. The water storage chamber accounts for 30-60% of the total volume of the water storage stone. %; the water-permeable layer is a porous cladding layer, and the porosity of the water-permeable layer is 10-25%. The artificial water storage stone of the present invention realizes the storage of rainwater through the water storage cavity and the permeable layer with water storage function, and the water storage capacity of the water storage stone reaches 0.4‑0.7t / m 3 , which is 2‑3 times that of natural stones in the same volume, which greatly improves the water storage capacity of the rain garden aquifer; at the same time, it can greatly reduce the excavation of deep pits in the rain garden, further reduce construction costs, and also reduce the occupied area. If it is in an area with a large amount of rainfall, compared with a rain garden of equal volume, the sustainability of stormwater control is also greatly improved.

Description

technical field [0001] The invention relates to the field of rain gardens, in particular to an artificial water storage stone and a preparation method thereof. Background technique [0002] With the continuous acceleration of urbanization, problems such as urban waterlogging and initial rainwater pollution are becoming more and more serious. The water system in the city continues to decrease, and the impermeable area of ​​the ground increases, resulting in the inability of rainfall runoff to infiltrate through the ground, resulting in serious waterlogging in the city after the formation of stagnant water. Current common solutions include permeable paving, grass ditch, and bioretention (rainwater gardens). The rain garden is a depression with both soil infiltration and rainwater storage functions. Through plant absorption, microbial degradation and soil medium filtration, it stores and purifies rainwater, and makes it gradually infiltrate the soil to conserve groundwater. F...
