<P>PROBLEM TO BE SOLVED: To provide a method of eliminating/preventing raise of bricks/curbstones on a foot pavement due to the street tree growing large. <P>SOLUTION: The method for preventing curbstones/paving stones from lifting due to laterally stretching roots of a street tree includes forming a cavity directly under the street tree, and making the street tree sag to the extent of the cavity by the empty weight of the street tree. Formation of the cavity directly under the street tree results in making the street tree sag by utilizing the empty weight of the street tree so as to reduce the raise of the roots. <P>COPYRIGHT: (C)2012,JPO&INPIT |
