Background

With the continuous acceleration of the urbanization process in China, the demand range of urban rail transit is continuously expanded, the urban subway traffic improves the urban development speed and saves the traffic land area, and the urban subway traffic is also the most favorable means for solving urban traffic jam. But on the other hand, the track laying base for urban rail construction is large in area and long in construction period, difficulty is brought to urban removal work, in addition, the length of the whole track panel is 25 meters, and a feed opening along the subway line cannot completely meet the requirement of lowering the whole track panel. In addition, the whole track panel can not be placed in a scattered mode when the whole track panel needs to be laid in a part of intervals or under special working conditions, and noise pollution, light pollution and the like caused by construction at night seriously disturb the production and life of surrounding residents, which are problems faced in the current track construction process. Therefore, the method has very important scientific research value and practical significance on how to effectively control and reduce the pollution problem generated in the construction process and improve the site utilization rate.

At present, no successful underground scattered paving prefabrication mechanized construction technology is applied in China. The technology mainly solves the defects of low efficiency, low degree of mechanization, high labor cost and the like in the process of scattered paving of the track, and simultaneously solves the problems of large occupied area of a track panel field, low field utilization rate and the requirement of driving under special working conditions. Therefore, on the premise of solving various defects and limiting conditions in the current construction process, the development of an economical and applicable scattered paving mechanized construction technology capable of quickly improving the construction efficiency is bound to be the forefront in the same technical field, and greater economic benefits and social benefits are created for companies.

The prefabricated track panel needs a construction unit to establish a track panel base for processing and assembling the track panel, then the prefabricated 25-meter track panel is hoisted to a flat car by adopting hoisting equipment and then is transported to a construction site by being dragged by the track car, and the prefabricated track panel is released from a limited space of scattered paving, so that the construction efficiency is greatly improved, the labor cost is reduced, but due to the construction in an external space, the illumination pollution and the noise pollution in the construction process also cause great troubles to nearby residents, and the construction unit is often complained. In addition, because a track panel base needs to be built, the land acquisition and removal difficulty of an owner unit is greatly increased due to the urban land with the small size of land, and the land utilization rate is not high. Under special conditions, the track panel base cannot meet the requirement of high-speed development of track laying construction at present because the track panels must be spread in holes in a scattered manner.
