Sidewalk-roadway combined block system improved rainwater permeability with gap

Abstract

A sidewalk-roadway combined block system with a gap, where side connection portions to which left and right sides of unit assembly blocks are physically inserted and coupled are formed, a gap portion is formed between a front surface and a rear surface of the unit assembly block, a groove portion composed of many grooves is formed on a top, and a hollow portion in which rainwater or a mixture dropping down from the gap portion is collected is formed at a lower portion.

What is claimed is: 
     
         1 . A sidewalk-roadway combined block system with a gap, wherein side connection portions to which left and right sides of unit assembly blocks are physically inserted and coupled are formed,
 a gap portion is formed between a front surface and a rear surface of the unit assembly block,   a groove portion composed of many grooves is formed on a top, and   a hollow portion in which rainwater or a mixture dropping down from the gap portion is collected is formed at a lower portion.   
     
     
         2 . The sidewalk-roadway combined block system of  claim 1 , wherein the unit assembly block is made of a concrete or synthetic resin material. 
     
     
         3 . The sidewalk-roadway combined block system of  claim 1 , wherein the gap portion formed between the front surface and the rear surface of the unit assembly block is formed such that a gap between blocks widens as it goes to a lower portion of the blocks. 
     
     
         4 . The sidewalk-roadway combined block system of  claim 1 , wherein the side connection portion is formed by forming a semicircular protrusion and a semicircular groove that can receive the semicircular protrusion to be able to replace the unit assembly block by inserting a tool through the gap portion formed between the front surface and the rear surface of the unit assembly block and lifting the unit assembly block. 
     
     
         5 . The sidewalk-roadway combined block system of  claim 1 , wherein the gap portion formed between the front surface and the rear surface of the unit assembly block is formed by forming one to five gap maintenance protrusions. 
     
     
         6 . The sidewalk-roadway combined block system of  claim 1 , wherein many hollow portions in which rainwater or mixture at a lower portion is collected are formed. 
     
     
         7 . The sidewalk-roadway combined block system of  claim 1 , wherein a hollow portion in which rainwater or mixture at a lower portion is collected is integrally formed at a lower portion of the unit assembly block. 
     
     
         8 . The sidewalk-roadway combined block system of  claim 1 , wherein many connection protrusions of the connection portions to which the left and right sides of the unit assembly blocks are inserted and fitted are formed in an overlap state to be fitted in a circular or rectangular groove. 
     
     
         9 . The sidewalk-roadway combined block system of  claim 1 , wherein the block system is used instead of a water channel at a side of a sloped road or used as a cavity member passing a communication cable, etc. by connecting lower cavity portions to be able to prevent a ground at a lower portion from becoming depressed using a second assistant unit assembly block manufactured in a shape in which a lower cavity portion is integrated with a block by adding a horizontal plate-shaped guide. 
     
     
         10 . The sidewalk-roadway combined block system of  claim 7 , wherein a portion corresponding to a passage of vehicles can be firmly assembled such that vehicle can go through using a fully solid first assistant unit assembly block without a lower cavity portion.
