Embodiment Construction

[0034] Examples see Figure 1 to Figure 7 As shown, an assembled sleeper for shield construction is formed by splicing a slag truck sleeper and a trolley sleeper. B6 and two connecting plates B7 are combined and welded. The hypotenuse of the trapezoidal plate 5 is arc-shaped, and its symmetrical vertical welding is at the center of both ends of the arc-shaped bottom plate B8. The top plate B6 is vertically welded on the top of the trapezoidal plate 5. On the surface, there are bolt holes 12 for connecting the pressure plate of the fixed slag truck rail 9, and the connecting plate B7 is vertically welded on the short side of the trapezoidal plate;

[0035] The trolley sleeper is welded by two right-angled triangular plates 2, two arc-shaped bottom plates A1, two top plates A3 and two connecting plates A4. The center of the bottom plate A1, the top plate A3 is vertically welded on the top surface of the right-angled triangle 2, and there are bolt holes 12 for fixing the trolley...

Abstract

The invention relates to an assembled tie for shield construction and a construction method thereof, belonging to the technical field of tie pavement in shield construction. The assembled tie is formed by splicing two trolley ties and a slag car tie; the baseplate of the assembled tie is cambered; and the existing joist steel ties are replaced by a cambered right-angled triangle plate and a trapezoidal plate. The assembled tie has the advantage of light weight and the like, is easy to stack, and can protect shielded duct pieces. In the construction process, the trolley ties at the back of the trolleys, which are not used any more, are continuously disassembled, thus improving the use ratio of construction members and effectively reducing the construction cost. The assembled tie and the construction method thereof can be widely applied to installing mechanical ties in the process of the shield construction.

Description

technical field [0001] The invention relates to a sleeper in shield construction and a construction method thereof. Background technique [0002] As the most advanced super-large special equipment for tunneling today, the shield machine is a high-tech construction equipment that realizes excavation, excavation, support, etc., and is widely used in urban rail transit, railways, highways, municipal administration, hydropower, etc. tunnel Engineering. [0003] Horizontal transportation in the tunnel is an important link in the shield construction process. At present, during the construction of the subway shield tunnel, the transportation sleepers in the tunnel are mostly made of H-shaped steel and I-shaped steel, with a spacing of 1 to 1.2m. As the shield tunnel advances, it is continuously laid until the tunnel is penetrated. This sleeper method has the disadvantages of consuming a large amount of steel, heavy weight, inconvenient handling, and difficult storage. [0004] T...
