Apparatus for preventing land subsidence around road structure

摘要

The present invention relates to an apparatus for suppressing land subsidence around a road floor structure. An objective of the present invention is to provide an apparatus for suppressing land subsidence around a road floor structure which increases a binding force between a road floor structure and the surrounding ground to effectively suppress subsidence of the surrounding ground. To achieve the objective, the apparatus for suppressing land subsidence around a road floor structure which comprises a support member and a cover member seated on an upper end of the support member and is constructed to allow an upper surface of the cover member to coincide with the road is buried and installed in the ground around a road floor structure to suppress subsidence of the surrounding ground. The apparatus comprises: a fixing frame comprising an inner wall extended along an outer surface of the support member, an outer wall formed in an annular structure which is separated from an outer surface of the inner wall and encloses the outer surface, and a floor plate connecting a lower end of the inner wall and a lower end of the outer wall to each other to seal a lower portion of a space formed between the inner wall and the outer wall; a plurality of binding guide protrusions formed on an upper end of any one wall among the inner wall and the outer wall; and a lattice net installed between the inner wall and the outer wall to have a structure covering an upper portion of the space formed between the inner wall and the outer wall. The apparatus for suppressing land subsidence around the road floor structure is buried in asphalt concrete deposited around the road floor structure while inserted and mounted on the outside of the support member to integrate the road floor structure and the surrounding ground to suppress subsidence of the surrounding ground.
