[0002] As a high-cost and high-efficiency mode of transportation, urban subways are usually built in densely populated areas in order to increase passenger flow during the operation period and reduce the pressure of principal and interest repayment. Subway stations are also often located on major traffic arteries where people gather. In order to reduce the impact on ground traffic, dark excavation or covered excavation construction is usually selected when conditions permit. There are often no hoisting shafts or only small hoisting shafts on the ground, which cannot meet the hoisting conditions of the subsequent supporting trolleys. This results in the need for the subsequent supporting trolleys to be horizontally transported in the tunnel to the large-sized hoisting shaft near the station and then hoisted to the ground.
