Abstract

PURPOSE: To restore economically the height of a settlement section by providing holes passing through a concrete paving slab, lifting the paving slab by a screw jack after forming a reaction panel on a subbase cource of the bottoms of the holes, and filling a filler into a void.
CONSTITUTION: Operating holes 3 passing through a paving slab (A) are bored on the whole area of a settlement area of the concrete paving slab (A), and the surface part of a foundation subbase course 5 under the holes and in the vicinity of them is excavated to form an operation space 6, and, at the same time, a reaction panel 7 is formed. Then, a disc-like fixed metal fixture 11 is placed on the reaction panel 7, and it is positioned to the inside of a cylinder 12 of a jack device metal fixture 10. The paving slab (A) is lifted by a screw jack, and a filler of sand, foaming cement mortar, etc. is filled in a space made between the paving slab (A) and the foundation subbase course 5.
