Detailed Description
Examples
The shield is hoisted by the outer side of the station body, and does not occupy the road in the current situation.
As shown in figure 1, the arrangement of the station wind pavilion is combined, a shield hoisting hole is arranged on the side of a station and outside a red line of a road, and the structure of the station wind pavilion is locally deepened to be level with the elevation of a bottom plate of a station end.
When starting, the shield machine is hung downwards from the shield hoisting hole, and then moves and rotates for 90 degrees after reaching the station end well along the direction of the path shown in the figure, and then the normal starting procedure can be started.
The shield receiving is similar to the starting, except that the direction of the transportation path is opposite, and the shield machine is called out through the shield hoisting hole.
The segment and the muck are hoisted and transported outside the station body, and the segment and the muck do not occupy the road in the current situation.
As shown in fig. 2, in combination with the arrangement of the station access, the unearthed holes are arranged on the side of the station and outside the red line of the road, and the station access structure is locally deepened to be flush with the elevation of the station main body bottom plate.
When the platform trolley is unearthed, the platform trolley is transported to the position of the unearthed hole along the direction of the path shown in the figure and is lifted out of the unearthed hole.
And the segments are lifted to the flat trolley from the unearthed holes and then transported to the position of the shield tunneling machine along the direction of the path shown in the figure for assembly. When the transportation path is arranged, the turning radius requirement of the flat-bed trolley is met.
In the method for constructing the station structural column on the transportation path, as shown in fig. 3, the pipe piece and the muck transportation path must meet the turning radius requirement of the flat-bed trolley, so that the position conflict between the transportation path and the station structural column is inevitably caused.
The processing method comprises the following steps: and arranging a temporary stand column in a way of avoiding the collision position, constructing the station structure column at the collision position after the shield construction is finished, and removing the temporary stand column after the stress conversion is finished.
The temporary upright column is preferably in the form of a steel pipe column or a section steel column and the like, and is convenient and rapid to erect and dismantle.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
