Construction method of separate sleepers and sleepers for the follow-up trolley and battery car system of the portable shield machine

Abstract

The invention relates to a construction method for a dividing sleeper of a portable novel shielding tunneling machine backup trailer and an accumulator car system, which is used for separating an accumulator car sleeper from a trailer sleeper, so as to be independent from each other. The method can reduce steel consumption, effectively lighten the weight of the sleeper, and is convenient for dismounting; a shield trailer and an accumulator car can respectively work steadily and reliably; labor intensity of workers is reduced, labor efficiency of workers is improved, and occurrence rate of safety accidents of workers is reduced; the sleeper is not easy to derail after being used, a trailer running system and a platform accumulator car running system are divided into two independent running systems which do not interfere each other, the trailer and the platform accumulator car do not interfere each other and run in respective independent track systems; and the production and operation safety performance are high, the effect is remarkable, and the mechanical efficiency of operation is high.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a method for constructing separate sleepers and sleepers for the follow-up trolley and battery car system of a portable shield tunneling machine Background technique [0002] The construction of the shield tunnel project is inseparable from the follow-up supporting trolley of the shield machine. The walking wheels of the follow-up supporting trolley of the track-type shield machine (referred to as "trolley" the same below) walk on the rails on the sleepers, and the rails There is a certain height from the bottom of the tunnel, and it is not a hindrance if there is water under the tunnel. Because the sleepers are relatively large, and the track sleepers of the flat-bed transportation battery car and the subsequent supporting trolley of the shield machine in the construction of the shield tunnel are a whole public Sleepers, and the common sleepers of trolleys and battery c...

AI Technical Summary

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

However, there are the following problems: (1) The track sleeper of the battery car for tunnel construction and the supporting trolley track sleeper behind the shield machine are not completely separated, and the two U-shaped sleeper components are connected by bolts, because the wheels of the battery car are concentrated when the flat-bed transport battery car is fully loaded with soil The load is the largest and the stress is the most concentrated. The horizontal section of the U-shaped component of the battery car is prone to displacement and structural deformation in the two directions of horizontal and vertical directions; (2) When the U-shaped component of the battery car is deformed, the U-shaped component of the trolley together with deformation together

Due to the existence of these two risk sources, there is a probability of derailment and a possibility of safety accidents
