Abstract

The invention provides an underground container logistics loading and unloading system based on a deep underground passage. The underground container logistics loading and unloading system comprises an automatic container wharf, a logistics park and the deep underground passage. The automatic container wharf is connected with the logistics park through the deep underground passage, and the deep underground passage internally comprises an area where shuttle vehicles run; and the deep underground passage comprises a main body layout area and accessory equipment. By applying the embodiment of the invention, through a vertical loading and unloading mode and an underground container logistics transportation mode, cargo transportation is realized, and transportation of ground container trucks is shunted to a certain extent, so that the ground transportation pressure of a port city is relieved, the transportation distance between the container wharf and the out-of-city logistics park is shortened.
