Constructing system of instant permeability and underflow pavement preventing from flood and method thereof

Abstract

The present invention is directed to a road payment system with instant rainwater penetration and storing functions for protecting flood and a construction method thereof, which system comprises a plurality of lower blocks which each have a vertical engaging wing formed at a side of each lower block and a first through hole formed at a center region, with the neighboring lower blocks being engaged with each other in a vertical direction for preventing them from being separated in a horizontal direction; a plurality of intermediate layer blocks which are arranged spaced apart in a horizontal direction at the upper sides of the lower blocks and each have a second through hole in a vertical direction at a center region, with the neighboring intermediate layer blocks being engaged with each other; and a plurality of upper surface layer blocks which are arranged at the upper sides of the intermediate layer blocks and form an upper side of the road payment and are connected with each other or are connected with the intermediate layer blocks in a horizontal direction.

1 . A road payment system with instant rainwater penetration and storing functions for protecting flood, comprising:
 a plurality of lower blocks which each have a vertical engaging wing formed at a side of each lower block and a first through hole formed at a center region, with the neighboring lower blocks being engaged with each other in a vertical direction for preventing them from being separated in a horizontal direction;   a plurality of intermediate layer blocks which are arranged spaced apart in a horizontal direction at the upper sides of the lower blocks and each have a second through hole in a vertical direction at a center region, with the neighboring intermediate layer blocks being engaged with each other; and   a plurality of upper surface layer blocks which are arranged at the upper sides of the intermediate layer blocks and form an upper side of the road payment and are connected with each other or are connected with the intermediate layer blocks in a horizontal direction.   
     
     
         2 . The system of  claim 1 , wherein the vertical engaging wing comprises:
 a first wing part formed at one side surface of the lower layer block; and   a second wing part formed at the other side surface of the lower layer block and fits the first wing part of the neighboring lower layer block in a vertical direction.   
     
     
         3 . The system of  claim 2 , wherein the lower layer block further comprises a water draining groove part formed at the region of the first wing part. 
     
     
         4 . The system of  claim 1 , wherein the neighboring intermediate layer blocks and the upper surface layer blocks comprise a plurality of arc shaped engaging arms which are engaged in vertical directions for thereby preventing them from being separated in horizontal directions, and a plurality of the arc shaped engaging arms are arranged in radial shapes in the circumferential directions of the upper surface layer blocks. 
     
     
         5 . The system of  claim 1 , wherein the connection blocks are cross shaped connection blocks which are arranged lower than the upper surfaces of the intermediate layer blocks. 
     
     
         6 . The system of  claim 1 , wherein the upper surface layer blocks comprise:
 first upper surface layer blocks arranged on the upper sides of the intermediate layer blocks; and   second upper surface layer blocks which are arranged on the upper sides of the connection block and are connected with each other or with the first upper surface layer blocks, and   the first upper surface layer block is thinner than the thickness of the second upper surface block.   
     
     
         7 . A road payment system with instant rainwater penetration and storing functions for protecting flood, comprising:
 a plurality of lower blocks which each have a vertical engaging wing formed at a side of each lower block and a first through hole formed at a center region, with the neighboring lower blocks being engaged with each other in a vertical direction for preventing them from being separated in a horizontal direction, and the lower layer blocks are stacked in a multistage-laminated structure in the direction of heights.   
     
     
         8 . An instant rainwater penetration and storing road payment method for protecting flood, comprising:
 manufacturing a lower layer with a plurality of a lower blocks which each have a vertical engaging wing formed at a side of each lower block and a first through hole formed at a center region, with the neighboring lower blocks being engaged with each other in a vertical direction for preventing them from being separated in a horizontal direction;   manufacturing an intermediate layer on an upper side of the lower layer with a plurality of intermediate layer blocks which are arranged spaced apart in a horizontal direction at the upper sides of the lower blocks and each have a second through hole in a vertical direction at a center region, with the neighboring intermediate layer blocks being engaged with each other; and   manufacturing an upper surface layer on an upper side of the intermediate layer with a plurality of upper surface layer blocks which are arranged at the upper sides of the intermediate layer blocks and form an upper side of the road payment and are connected with each other or are connected with the intermediate layer blocks in a horizontal direction.
