FLEXIBLE NON-JOINTING STRUCTURE OF ROAD AND BRIDGE INSTALLATION USING WATERPROOFING MEMBRANE AND CONSTRUCTING METHOD THEREOF

摘要

The present invention provides a flexible non-jointing structure of underground road and bridge using a waterproof coating membrane without a need of providing a flexible jointing structure for an ascon paving layer by providing a waterproof coating membrane on a top surface of a concrete structure underneath the ascon paving layer of the underground road and the bridge and installing a grid between the ascon paving layer and the concrete structure to absorb strain due to expansion and contraction of the concrete structure and prevent the strain to be transferred to the ascon paving layer; and a method for constructing the same. The flexible non-jointing structure of underground road and bridge using a waterproofing coating membrane according to the present invention comprises concrete slabs installed at a desired distance and having drain pipes for underground water inserted in the distance; primer layers coated on tops of the concrete slabs; a waterproof coating membrane layer formed on the entire top of the primer layers and the drain pipes for underground water; a lattice grid installed on a top of the waterproof coating membrane layer; and an ascon paving layer paved on a top of the grid, in which the top surfaces of the concrete slabs are provided with grooves for inserting the drain pipes at a constant distance in a slope of 20~50to a longitudinal direction of the road, and drain pipes for percolation water are inserted in the grooves for inserting the drain pipes.
