Abstract

The invention discloses an overall launching method of a shield machine underground. The shield machine includes a main body of the shield machine, a connecting bridge and a trolley group; the length of the launching shaft is less than the length required for the overall launch of the shield machine; The method comprises the steps of: the set of trolleys comprises at least two trolleys; decomposing at least one trolley into a first part and a second part, and fixing the first part to one side of the other trolley, Fixing the second part to the other side to form a trolley complex; the trolley complex can move along the starting direction in the launch shaft; after the above steps are completed, the shield machine starts to move in the launch shaft send. In the vertical whole starting method of the present invention, the refitting and restoration of the shield machine trolley is simple, the cost is low, and the starting speed is fast, which solves the problems of the short starting shaft length of the shield machine and the narrow construction site, and can save the construction period and reduce the engineering cost. cost.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling method construction, and in particular relates to an underground integral starting method of a shield tunneling machine. Background technique [0002] The origination of the shield refers to the fact that the shield is positioned in the installation shaft or the passing shaft, the cutter head is pushed forward and penetrates into the surrounding rock, and the shield is driven forward along the design line until the shield safely enters the interval tunnel or opening until the reaction frame and the negative ring segments are removed. The starting of the shield machine is one of the key links in the shield construction. Its main contents include: installation of the starting bracket of the shield machine, assembly and commissioning of the shield machine, installation of the reaction force frame and the door sealing water-stop device, installation of the load Ring segment, shield machine t...
