Abstract

The invention provides a shield construction system, which includes a shield receiving shaft and a turn-back belt conveyor assembly, wherein the shield receiving shaft is arranged on the tunneling route of the shield machine, and in the direction of tunneling of the shield machine, the shield The first tunnel and the second tunnel are respectively formed on both sides of the machine receiving shaft, and the shield receiving shaft is used to initiate the second shield machine and receive the first shield machine; at least a part of the return belt conveyor assembly is arranged in the second tunnel , to be used to automatically transport the muck produced by the second shield machine to the ground when excavating the second tunnel; in the direction of shield machine excavation, the width of the part of the return belt conveyor assembly located in the shield receiving shaft is the same as The ratio of the width of the shield receiving well is greater than 0 and less than or equal to 30%. The invention solves the unreasonable layout of the belt conveyor and the receiving shaft of the shield machine in the prior art, which causes the shield machine to be unable to be received normally, slows down the progress of the shield machine construction, prolongs the construction period of the shield machine, and improves the construction efficiency of the shield machine. The cost of shield construction.

Description

technical field [0001] The invention relates to the technical field of shield tunneling construction, in particular to a shield tunneling construction system. Background technique [0002] During the construction of subway tunnels, the shield method is widely used due to its high degree of mechanization, construction safety, and good adaptability. The common shield method is to use a shield machine for shield tunneling. [0003] In the process of shield tunneling construction, the route of shield tunneling construction is usually divided into multiple excavation sections, and each excavation section has at least one shield tunneling machine for shield excavation. In tunnels, a belt conveyor is usually set at the starting position on the tunneling route of the shield machine, and the starting position of the shield machine happens to be the receiving position of another shield machine in the adjacent excavation section, usually the shield machine is set The receiving well re...
