Abstract:
This invention relates to a cut and cover method of constructing grade separation structures. The methods include partially burying precast substructure elements with associated trench boxes under live traffic. Once the precast substructure elements are buried the substructure is completed and the bridge span is installed. Other methods include installing precast superstructure elements with form-work system and forming a bridge substructure and excavating underneath the superstructure once the substructure is formed.

Claim (Index 1):
A method for constructing a grade separation structure at intersection of two thoroughfares comprising:\n installing pairs of caisson liners along a first thoroughfare; wherein the caisson liners are substantially centred on the intersection; providing pre-cast concrete segment with a first end and second end; connecting a modular trench box to the first end of the precast segment and connecting a second modular trench box to the second end of the precast segment to form a pre-cast assembly; excavating a trench across the thoroughfare and around a pair of caisson liners, wherein the trench is sized to accommodate the precast assembly; installing the precast assembly in the trench such that a first caisson liner is position in the first trench box and a second caisson liner is positioned in the second trench box; filling the trench with ballast material thereby burying the precast assembly; filling the first and second caisson liners with reinforced cast-in-place concrete; linking the precast segments to the caissons; installing bearings and finishing works on the caissons to complete bridge substructure; preparing the completed bridge substructure for bridge span installation; and installing bridge span; wherein following installation of the bridge span underpass is excavated and thoroughfares reinstated.
