Abstract

The invention discloses a donwhole integral launching method for a shield tunneling machine. The shield tunneling machine comprises a shield tunneling machine body, a connection bridge and a trolley group. The length of a launching well is smaller than the length needed by integral launching of the shield tunneling machine. The method includes that the trolley group comprises at least two trolleys; at least one trolley is disassembled into a first part and a second part, the first part is fixed on one side of another trolley, and the second part is fixed on the other side of the trolley to form a trolley combination; the trolley combination can move in the launching well along the launching direction; the shield tunneling machine is launched integrally in the launching well after the steps are completed. The donwhole integral launching method has the advantages that the trolleys of the shield tunneling machine are simple to refit and recover, low in cost and high in launching speed, the problems of short length of the shield launching well and narrowness of a construction site are solved, construction period can be shortened and construction cost can be reduced.

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...
