Scattered paving method mechanized construction equipment for urban railway and construction method thereof

Abstract

The invention relates to the technical field of engineering construction, in particular to scattered paving method mechanized construction equipment for an urban railway and a use method thereof. Thescattered paving method mechanized construction equipment comprises a rail row hoisting door machine device, a flip door machine system, a prefabricated flat car system and a transfer rail car, wherein the prefabricated flat car system comprises running rails; the flip door machine system is fixed on the running rails of the prefabricated flat car system through a rail clamping device; and the transfer rail car is connected with the prefabricated flat car system through a rail car connector. The scattered paving method mechanized construction equipment provided by the invention is a scatteredpaving method construction machine for a shaped rail, forming a complete set of construction technology. Meanwhile, the construction quality of an underground scattered track section is improved, theprefabrication time of the track section is shortened, the labor required for scattered track laying operation is reduced, the construction cost is reduced, the construction efficiency is improved, the mechanization of the underground scattered track section is realized, and the technical level of scattered track laying is comprehensively improved, thereby further enhancing the technical level andcapability of construction.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a mechanized construction equipment and a construction method of urban rail scattered laying method. Background technique [0002] With the continuous acceleration of my country's urbanization process, the scope of demand for urban rail transit is also expanding. Urban subway transportation has improved the speed of urban development and saved the area of ​​traffic land. It is also the most favorable means to solve urban traffic congestion. But on the other hand, the track laying base used for urban rail construction has a large area and a long construction period, which brings difficulties to the urban demolition work. In addition, the overall length of the rail row is 25 meters, and the material openings along the subway line cannot fully meet the requirements of the overall rail row. Decentralize work. In addition, some intervals or special working conditions...

AI Technical Summary

Problems solved by technology

[0004] Subway track laying construction is mainly based on prefabricated rail laying and loose laying rail laying construction. Among them, loose laying construction mainly transports track laying materials, such as steel rails, fasteners, sleepers and other construction materials to the construction site, and assembles the rail laying by forklift or manually. Its main disadvantages are low construction efficiency, limited space, difficult material transfer, poor protection effect of finished materials, and high labor costs.

The prefabricated rail row requires the construction unit to establish a rail row base for processing and assembling the rail row, and then use lifting equipment to hoist the prefabricated 25-meter rail row onto the flatbed truck, and then be towed and transported to the construction site by the rail car, while the prefabricated rail row The row is liberated from the limited space of scattered paving, which greatly improves the construction efficiency and reduces the labor cost. However, because it is constructed in an external space, the light pollution and noise pollution during the construction process also cause great troubles to nearby residents. The construction unit often complained about

In addition, because of the need to build a rail base, the urban land is very expensive, which greatly increases the difficulty of land acquisition and demolition for the owner unit, and the land utilization rate is not high

Under special circumstances, it is necessary to lay loosely in the cave, and the track laying base cannot meet the needs of the current rapid development of track laying construction
