technical field

The utility model relates to the technical field of engineering construction, in particular to a mechanized construction equipment of the urban track scattered paving method.

Background technique

With the continuous acceleration of urbanization in my country, the demand for urban rail transit is also expanding. Urban subway transit improves the speed of urban development and saves the area of traffic land, and is also the most favorable means to solve urban traffic congestion. 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 length of the overall rail row is 25 meters, and the discharge port along the subway line cannot fully meet the requirements of the overall rail row. Delegate work. In addition, some sections or special working conditions require scattered laying operations, which cannot meet the decentralization of the overall rail row. In addition, noise pollution and light pollution caused by construction at night seriously trouble the production and life of surrounding residents. These are all faced in the current rail construction process. The problem. Therefore, how to effectively control and reduce the pollution problems in the construction process and improve the utilization rate of the site has very important scientific research value and practical significance.

At present, no successful underground laying prefabricated mechanized construction technology has been applied in China. This technology mainly solves the shortcomings of low efficiency, low degree of mechanization and high labor cost in the process of track laying. Therefore, under the premise of solving the various drawbacks and limitations in the current construction process, the development of an economical and applicable scattered mechanized construction technology that can quickly improve construction efficiency will definitely stand at the forefront in the technical field of the same industry. The company creates greater economic and social benefits.

The subway track laying construction is mainly based on the prefabricated track row and the scattered track laying construction. The scattered laying construction is mainly to transport the track laying materials, such as: steel rails, fasteners, sleepers and other construction materials to the construction site. Its main disadvantages are low construction efficiency, difficult material transfer due to space constraints, poor protection 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 to the flatbed car, and then be pulled by the rail car to the construction site. The row is liberated from the limited space of scattered paving, which greatly improves the construction efficiency and reduces labor costs. However, because the construction is carried out in an external space, the light pollution and noise pollution during the construction process also cause great trouble to the nearby residents. The construction unit Often complained. In addition, due to the need to build a rail row base, the urban land is expensive, which greatly increases the difficulty of land acquisition and demolition of the owner unit, and the land utilization rate is not high. Under special circumstances, it must be scattered in the hole, and the track base cannot meet the needs of the current rapid development of track laying construction.
