<p>Shelters as shown in Figure 3, are constructed by filled bags (1), which typically have a trapezoidal cross-section. Such bags are divided into several compartments by internal webs (3) and can be laid over an arched lining (2). In end view, the bags are slightly wedge-shaped so that they resemble stones following the curve of a masonry arch, and the webs (3) follow the curve of the arch so that there is an inner compartment (4), a middle compartment (5), and an outer compartment (6) in each bag. In addition to shelters, the bags can be used to build barriers formed of courses of bags, with at least one side of the barrier having a corbelled out portion.</p> |
