The invention provides a mobile vertical compression pit horizontal waste compression station. The mobile vertical compression pit horizontal waste compression station comprises a pit, wherein a mobile press is arranged at the top of the pit, a compression box body and a lifting device thereof are arranged in the pit, a feed inlet is arranged at the top of the compression box body, a discharge outlet is arranged on the front surface of the compression box body, a compression head and a driving device thereof are arranged in the mobile press, and the driving device can drive the compression head to move in the vertical direction in a reciprocating manner; and two sections of guide tracks are respectively arranged at the feed inlet at the top of the compression box body and in the corresponding position on the ground, when the compression box body is positioned in the pit, the two sections of the guide tracks are connected, and matching rolling wheels are arranged at the bottom of the mobile press. The mobile vertical compression pit horizontal waste compression station provided by the invention has the advantages of high degree of automation, good motion control effect and capability of realizing zero pollution emission, and can save space height, occupy small area, save investment cost, realize shorter stroke of a mobile compression oil cylinder, and realize stable and safe operation, convenience in mounting and very low maintenance cost; and the mobile vertical compression pit horizontal waste compression station is rapid in establishment and economic in collection and transportation, has no secondary pollution, and can solve the difficult problem that a built house which is vertically compressed in the past is high.
