Method for correcting concrete plate tilting on subsided ground
This invention addresses the problem of providing a method for correcting tilting due to the sinking of a joint of adjacent concrete plates for which the joint is connected by tie bars and dowel bars and that are on subsided ground. As a solution, this method includes a step of pushing up a tilted concrete plate by: drilling an injection hole for injecting an expansion resin at a point 10 to 200 cm distant from a joint of one concrete plate of adjacent concrete plates with a sunken joint as the boundary and at a point 10 to 200 cm distant from a joint of the other concrete plate, this joint being on a line orthogonal to the joint on line with the other point; simultaneously starting intermittently injecting the expansion resin from both of the injection holes; and expanding the expansion resin under both concrete plates.
