Permeable Capsule

Abstract

This invention designed a Permeable Capsule to make the traditional pavements such as asphalt, concrete, stone pavers to become permeable to stormwater. Permeable Capsule reduces water pollution and replenishes groundwater in paved areas. Permeable Capsule allows traditional asphalt, concrete, as well as block-pavers (existing or new) surfaces to become permeable.

1 . This invention designed permeable capsule to be used on asphalt, concrete, and block pavers paved surface to allow stormwater to infiltrate into the grounds under such paved surfaces. 
     
     
         2 . According to  claim 1 , Permeable Capsule consists of Grid Cap, Mulches, Bottom Grid, and Side Wall. 
     
     
         3 . According to  claim 2 , Permeable Capsule can take various shapes and heights according to the needs.  FIGS. 1 and 2  are two examples of round and rectangular forms of Permeable Capsules. 
     
     
         4 . According to  claim 2 , Grid Cap filters out large objects such as leaves, papers, etc. and allows stormwater to flow into Permeable Capsule. Grid Cap can be made of materials such as plastics, wood-plastics composites, metals, and etc. 
     
     
         5 . According to  claim 2 , the mulches that are under Grid Cap and on top of Bottom Grid allow stormwater to flow through. The mulches can be any of these materials as follows: wood chips (mulch), recycled rubber tire chips, rocks, and etc. 
     
     
         6 . According to  claims 2  and  5 , the Bottom Grid holds mulches and allows stormwater to flow through. Bottom Grid can be made of materials such as plastics, wood-plastics composites, metals, and etc. 
     
     
         7 . According to  claims 2 ,  5 , and  6 , Bottom Grid can be mounted on the Side Wall or onto Grid Cap. 
     
     
         8 . According to  claims 2 ,  5 ,  6 , and  7 , Bottom Grid may not be used and to let mulches to sit on to the ground soil directly. 
     
     
         9 . According to  claim 2 , the bottom of Permeable Capsule is open and allows stormwater to go to and infiltrate through the soils. 
     
     
         10 . According to  claim 2 , Side Wall can be made of plastics, wood-plastic composites, metals, concrete, and etc.
