Problems solved by technology

The disadvantage of the scheme is that the laying method of large sleepers is still the large-gauge continuous sleepers using railway sleepers, the weight of a single sleeper is still relatively large, and it takes a lot of manpower to disassemble and assemble when it is recycled, and it takes a long time

Embodiment Construction

[0021] The features of the present invention and other relevant features are described in further detail below in conjunction with the accompanying drawings through the embodiments, so as to facilitate the understanding of those skilled in the art:

[0022] Such as Figure 1-7 , marks 1-14 in the figure are: I-beam 1, rail 2, limit bolt hole 3, horizontal steel plate 4, vertical steel plate 5, reinforcement rib 6, reinforcement rib 7, limit steel plate 8, limit shaft 9, Bolt holes 10, hand holes 11, sleepers 12, sleepers 13, shield segments 14.

[0023] Example: such as Figure 5 , 6 , 7, this implementation takes the tunnel engineering using the shield method as an example for illustration. During the tunneling construction of the shield machine, the shield trolley behind the shield machine is required to follow the large-gauge sleepers of the shield machine in the tunnel 12 and move forward, and the soil body cut by the shield cutter head and the segments assembled into t...

Abstract

The invention relates to an independent shield trolley sleeper and a construction method thereof. The sleeper comprises a horizontal steel plate with a supporting surface, a vertical steel plate and a limiting steel plate, wherein the vertical steel plate and the limiting steel plate are used for bearing the horizontal steel plate; and the shape of the bottom edge of the vertical steel plate is matched with that of an inner arc surface of a shield segment, the dimension of an outer outline surface of the limiting steel plate is matched with that of an inner outline surface of a hand hole on the shield segment, a limiting shaft is arranged at the lower end portion of the limiting steel plate, and the diameter of the limiting shaft is matched with that of a bolt hole axially arranged in the hand hole of the shield segment. The independent shield trolley sleeper has the advantages of being simple in structure, greatly reducing consumption of steel materials, effectively reducing the weight, and enabling a shield trolley to move stably and reliably by being adhered onto the shield segment stably. Simultaneously, by adopting the structure, the sleeper is fast and convenient to detach when used circularly, reduces investment of manpower and time and improves the extending speed of a rail arranged on the sleeper.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to an independent shield trolley sleeper and a construction method thereof. Background technique [0002] With its unique advantages, the shield method has been widely used in tunnel construction all over the world. Horizontal transportation in the tunnel is an important link in the process of shield tunneling. A practical and reasonable horizontal transportation system can make the entire shield construction process faster, more effective, safer and more economical. [0003] During shield construction, the follow-up trolley of the shield is required to follow the shield machine and move forward on the sleeper in the tunnel; the soil cut by the shield cutter head and the segments used for assembling the tunnel are transported by a flatbed transport vehicle. Transport on sleepers. In the past construction, the laying of the sleeper imitated the sleeper of the r...
