Geology grading manufacturing method with disaster prevention and ecological functions

Abstract

Provided is a method for manufacturing geological gradation layer (30) featuring disaster prevention and ecologic function, which uses on-site earth or gradation materials commonly adopted in road construction, including aggregates, soils, gravels, or a mixture of water permeable concrete, and most importantly, added with uniquely arranged hollow bodies (31), all constituents being mixed and laid on soil stratum (20), and subjected to ramming, to form an ecological gradation layer (30). The ecological gradation layer (30) provides an effect of supporting and also provides the functions of water storage, water preservation, and improving earth, whereby earth microorganisms and earth protozoa may establish a beneficial survival environment in earth, making the gradation layer exhibiting the characteristics of high water content and prompting breeding of microorganisms. When the atmosphere gets hot, water is released from the soil as vapor to alleviate the heat island effect and when rainwater precipitates, the rainwater can be stored for use in draughts.

Description

technical field [0001] The present invention relates to the design of a geological gradation manufacturing method with disaster prevention and ecological functions, especially a kind of pavement or under the pavement laid on roads, courtyards, and open spaces, which can be constructed to form an ecological gradation layer under the ground. When the rainwater infiltrates on the surface above the gradation layer, the rainwater can be effectively and quickly guided and stored in the gradation layer, which can store water in a short time to reduce the occurrence of floods, and can promote the microbial growth in the soil or Protozoa in the soil obtain a better breeding environment, which can keep the soil moist to adjust the temperature and humidity of the environment, and achieve the function of improving soil quality. Background technique [0002] Since ancient times, the soil has the function of absorbing water and can be in contact with the atmosphere. When the atmosphere is...

Problems solved by technology

[0003] Most of the graded layers in the underground with traditional common technology use general road engineering graded materials or according to the local existing earthwork, including filling with sand, gravel, soil, gravel or mixed permeable concrete. Although such a composition has the potential The function of infiltrating rainwater, and its gradation can support the bearing capacity of the upper pavement, but when such a traditional gradation encounters heavy rain on the ground, the traditional gradation layer has poor function of quickly draining rainwater, so it is easy to make the ground accumulation of water, causing floods
