Abstract:
This application relates to a light-weight, multi-purpose construction panel. The panel may be formed, for example, from molded plastic. Each panel includes a substantially planar deck on a first side thereof and a second side comprising alternating male and female sleeves arranged in honeycomb-like compartments defined by a plurality of wall elements. A pair of panels may be releasably coupled together with their respective second sides facing inwardly to form a construction assembly. When a pair of panels is coupled together, the male sleeves of one panel matingly fit within the females sleeves of the other panel, and vice versa. Each panel may also include guide tubes which are aligned when the panels are coupled together. A plurality of channels may be formed in the deck on the first side of the panel and spaced-apart apertures may be arranged in the channels in alignment with the guide tubes for insertion of fasteners therein or to allow water drainage through the assembly. The wall elements may include spaced-apart notches which together define conduits extending through the interior of an assembly when a pair of panels are coupled together. The conduits are sized to receive fluid delivery tubes for delivering fluid, such as heated air or water, through the panel assemblies. The panel assemblies may be used for many different construction applications including flooring, roofing and wall structures.
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.
Abstract:
Provided is a method for manufacturing artificial paving that helps improving global warming. A water permeable paving layer (40) is provided under which a drain layer (30), which includes gravels or sand, is selectively formed, and an interfacing layer (20) is formed under the drain layer (30). An ecological gradation layer (10) is set and rammed. The underside ecological gradation layer (10) provides an effect of supporting and, due to the ecological gradation layer (10) containing therein hollow bodies (11), which can be embodied as disaster-prevention water-storage hollow bodies (11) or earth-improvement hollow bodies (11) or microorganism-culture hollow bodies (11) or water-keeping hollow bodies (11) as desired, allows rainwater falling on ground surface to quickly penetrate down into the underground location, makes the ecological gradation layer (10) effectively preserve water in high water content, and prompt breeding of microorganisms, whereby when the atmosphere is of a high temperature, underground humidity can be released through drainpipes (41) that constitute the water permeable paving.

Abstract:
PROBLEM TO BE SOLVED: To provide a construction method of a geological gradation layer having disaster prevention and ecological preservation functions.SOLUTION: The present invention forms an ecological gradation layer not only by adopting local soils including sand and stone, clay, crushed stone or water permeable concrete mixture, or a gradation material generally used for road construction, but also by mixing hollow bodies having a most important special function. In addition to having a function to support a road surface, the ecological gradation layer is effective in storing water, retaining water and improving soil, and capable of creating beneficial environment for soil microorganisms and protozoa in soil to live in the soil. The ecological gradation layer can enhance a water retaining capacity of the soil and reproductive power of the soil microorganisms and thereby: alleviating a heat-island phenomenon by allowing water in the soil to evaporate when an atmosphere temperature is high; and preserving water in anticipation of drought as well as reducing a risk of an occurrence of flood damage above the ground by retaining and storing water during a rainfall.

PROBLEM TO BE SOLVED: To provide a method for manufacturing an artificial road surface that improves global warming.SOLUTION: An artificial water permeable road surface 40 is laid, a high speed water guiding layer 30 is provided in the lower layer of the water permeable road surface 40, the high speed water guiding layer 30 includes gravels or sand, an interfacing layer 20 is provided in the lower layer of the high speed water guiding layer 30, and then a hardened ecological gradation layer 10 is provided further. By the structure, the ecological gradation layer 10 of the lower layer has an effect of supporting and, by providing hollow bodies inside the layer (providing disaster-prevention water-storage hollow bodies, earth-improvement hollow bodies, microorganism-culture hollow bodies or water-keeping hollow bodies as needed), allows rainwater falling on ground surface to quickly penetrate underground, preserves a lot of water, and prompts breeding of microorganisms. When the temperature of the atmosphere is high, underground humidity is evaporated through pipe bodies of the water permeable road surface 40 and environment warming is improved.
