Method for manufacturing geological gradation featuring disaster prevention and ecologic function

Abstract

Provided is a method for manufacturing geological gradation layer 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, all constituents being mixed and laid on soil stratum, and subjected to ramming, to form an ecological gradation layer. The ecological gradation layer 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.

I claim: 
     
         1 . A method for manufacturing geological gradation featuring disaster prevention and ecologic function, characterized in that:
 the geological gradation is formed of gradation materials for road construction or on-site earth, the gradation comprising hollow bodies arranged therein, each of the hollow bodies defining through apertures, the hollow bodies being mixed with the gradation materials to form the gradation.   
     
     
         2 . The method according to  claim 1 , wherein the hollow bodies are constructed as earth-improvement hollow bodies, which have hollow interior spaces in which a carbon-contained substance or an earth-improvement agent is deposited. 
     
     
         3 . The method according to  claim 1 , wherein the hollow bodies are constructed as microorganism-culture hollow bodies, which have hollow interior spaces in which microbial strains are set. 
     
     
         4 . The method according to  claim 1 , wherein the hollow bodies are constructed as water-keeping hollow bodies, which have hollow interior spaces in which a water absorption substance, including sponge or a water absorptive material that is not decomposable by microorganisms, is deposited. 
     
     
         5 . The method according to  claim 1 , wherein each of the hollow bodies forms through apertures and is composed of two halved shell members that mate each other. 
     
     
         6 . The method according to  claim 1 , wherein each of the hollow bodies forms through apertures and is integrally formed as a unitary body through blow molding. 
     
     
         7 . The method according to  claim 1 , wherein each of the hollow bodies forms through apertures and is integrally formed as a unitary body through perfusion molding. 
     
     
         8 . The method according to  claim 1 , wherein the hollow bodies that are arranged in the gradation layer are accommodated in plurality in a bag net to form a bag-contained hollow body unit.
