The invention provides a detachable type emergency bridge made of a
composite material. The emergency bridge is of a wheel
rut structure, and is formed by splicing a plurality of bridge segments, wherein each bridge segment is of the structure of a multi-cavity box beam, and is made from a
resin matrix composite, particularly an
epoxy resin matrix hybrid fiber reinforced
composite material; each bridge segment comprises an upper faceplate, a lower faceplate and a plurality of intermediate webs, intermediate
layers of the upper faceplate and the lower faceplate are made from + / -45DEG E-
glass fiber, one 90DEG E-
glass fiber layer is arranged at each of both the upper side and the lower side of each intermediate layer, and a 0DEG carbon
fiber layer is arranged at the outer side of each 90DEG E-
glass fiber layer; and the webs employ a
composite material layer made from + / -45DEG E-glass
fiber. According to the invention, main bodies of a bridge body are made from the composite materials, and are assembled to form a whole through
metal connectors, so that the bridge body is light in weight, and convenient and quick to assemble, and can be manually assembled and disassembled quickly.
