METHOD OF CONSTRUCTING A CURVED STRUCTURE AND APPARATUS FOR PERFORMING SUCH METHOD

摘要

This invention relates to a method of constructing a curved structure and apparatus for performing such method. More specifically, the invention relates to a method and apparatus fort he construction of dome-like structures, particulary for the application of constructing an aqueduct or viaduct. The method includes the steps of erecting a curved support base (30) and layering one or more moulds over the curved support base (30). The moulds (34) comprise outer walls defining an outer perimeter thereof and inner walls dividing an interior oft he mould (34) into an array of adjacent compartments, wherein the mould (34) is flexible so as to substantially conform to the curvature of the curved support base (30). Once the mould (34) have been laid over the curved support base, each of the compartments of the mould (34) are filled with a settable material such that on curing, and removal oft he support base (30), a curved structure made up of a plurality of individual in-situ casted block is constructed. Preferably, the moulds (34) include formations that enable the blocks cast in-situ therein to interlock.
