Embodiment 1

[0034] A shield machine split start excavation pipeline extension supporting device, its structure please refer to Figure 1 to Figure 7 .

[0035] Such as figure 1 with figure 2 As shown in the figure, the shield machine’s split start excavation pipeline extension support device includes a track 2 installed on the segment lining 11 of the start tunnel 1. The track 2 is made of I-beams connected end to end, and the intervals on the track 2 are fixed. A plurality of hanging boards 21 are provided, the lower ends of the hanging boards 21 are welded on the track 2 , and the tops of the hanging boards 21 are fixed on the segment lining 11 . combine image 3 with Figure 4 As shown, the segment lining 11 is provided with a bolt hand hole 111, and a screw sleeve 112 for connecting the hanging plate is pre-embedded on the side of the bolt hand hole 111. The segment lining 11 is assembled from prefabricated segments. The screw sleeve 112 is pre-embedded in the piece, and the scr...

Embodiment 2

[0039] A separate starting method of the shield machine, please refer to Figure 8 to Figure 10 .

[0040] In this shield machine split start method, the shield machine split start excavation pipeline extension supporting device in Embodiment 1 is used. The split initiation method of the shield machine comprises the following steps:

[0041] (1) Lower the main engine of the shield machine into the starting working well, and after the main engine is placed in the starting working well, start excavation at the working face in the starting working well.

[0042] In this step, the starting working shaft is a vertical shaft constructed at the selected construction starting position on the tunnel construction route. Due to the limitation of construction cost and construction area, it is unrealistic to construct a starting working shaft that can accommodate the entire shield machine However, it is more reasonable to build a starting working shaft that can accommodate the main engin...

Abstract

The invention discloses a shield tunneling machine split starting tunneling pipeline extending and supporting device and a shield tunneling machine split starting method. The shield tunneling machine split starting tunneling pipeline extending and supporting device comprises a track installed on a segment lining of a starting tunnel, the track is fixed to the segment lining through a hanging plate, a plurality of slidable hanging frames are arranged on the track, and the bottoms of the hanging frames are connected with hanging rope assemblies used for supporting a pipeline at the tail of a shield tunneling machine main machine. In the shield tunneling machine starting method, the pipeline at the tail of the shield tunneling machine main machine can be hung through the supporting device, the pipeline is prevented from being supported on the ground in the starting tunnel, and therefore in the shield tunneling machine starting process, the pipeline cannot be soaked in water or dragged and abraded, and the pipeline is prevented from being crushed by engineering machinery; and the pipeline is hung, so that the space in the starting tunnel is more orderly, and the interference of disorder of the pipeline on construction is avoided.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a shield machine split start excavation pipeline extension supporting device and a shield machine split start method. Background technique [0002] The excavation construction method of shield tunnel is used more and more in underground space, especially in urban subway projects and water conservancy projects. When initially installing the shield machine into the starting position of tunnel excavation, due to the limitation of the space of the starting working shaft, more and more shield machines need to adopt the split starting method. stage, because the trailer at the back of the shield machine has not yet been installed in the well, and the reel equipped on the trailer for holding cables and liquid pipelines and other pipelines has not been officially put into use, resulting in the pipeline at the tail of the shield machine being mopped and soaked in water , being da...
