Embodiment
[0035] Example: such as Figure 1-11 As shown, this embodiment relates to a construction method in which the complex steel sleeve and the shield machine are separated and translated, and the steps of the construction method are:
[0036] a. If figure 1 and figure 2 As shown, a horse bench 3 is set up in the hoisting shaft 1, and steel plates are laid towards the station 2. The hoisting shaft 1 communicates with the closed starting shaft 6 through the transportation channel. There are 4 columns 5 and 4 columns 5 in the transportation channel. Arranged in a square shape, the track 4 is laid in the transportation channel, and the track 4 extends to the hoisting shaft 1 and the originating shaft 6. The track 4 includes the trolley walking track, the trolley walking track and the active transport track, and the active transport track is set on the column 5 During the period, the trolley, the trolley and the shield can move through the trolley walking track, the trolley walking t...

The invention discloses a construction method for split translation of a complex steel sleeve and a shield tunneling machine. The construction method comprises the following steps: a horse stool is erected in a hoisting well, a steel plate is paved towards a station, the hoisting well communicates with a closed starting well through a conveying channel, a plate trailer walking track and a trolley walking track are paved in the conveying channel, a plurality of stand columns are arranged in the conveying channel, and movable conveying tracks are arranged among the stand columns; a trolley, a plate trailer, a screw conveyor and a connecting bridge are hoisted into the hoisting well, the screw conveyor and the connecting bridge are installed on the plate trailer, the trolley, the screw conveyor and the connecting bridge are moved to the starting well through the plate trailer walking track and the trolley walking track, and the trolley, the screw conveyor and the connecting bridge are pulled into the station; a translation platform is erected in the hoisting well, a shield tunneling machine head is divided into two sets of assemblies, namely the first set of assemblies and the second set of assemblies, and the two sets of assemblies are both placed on the translation platform; and the screw conveyor is hoisted, and after the screw conveyor is installed, the connecting bridge and the trolley are pulled to the shield tunneling machine head.
Description
technical field [0001] The invention relates to the technical field of tunnel excavation construction, in particular to a construction method in which a complex steel sleeve and a shield machine separate and translate. Background technique [0002] At present, in the construction of urban subway tunnels in my country, the shield method has become the preferred method for urban rail transit construction. At some transfer stations, since there is no shield hoisting port reserved, the shield machine can only be moved to the starting point of the shield tunnel on the other side of the station by means of translation. Due to the large size and mass of the shield machine, and the constraints of planning and construction (such as underground stations, the design space is often small or the structure is complex), especially the shield machine in the case of small space and no large-scale mechanical assistance The origin problem of machine translation assembly is quite difficult. T...
