Description

Technical Field

[0001] The present invention belongs to the technical field of urban rail transit engineering, and in particular relates to an assembly device for a superimposed assembled underground station in an urban rail transit engineering. Background Art

[0002] There are two traditional construction methods for underground stations in urban rail transit projects. One is the cast-in-place concrete construction process, which requires setting up formwork and supports underground and pouring concrete. After the concrete strength meets the requirements, the formwork and supports are removed, and the formwork and supports are set up again in the next pouring area to pour concrete.

[0003] However, this method has the following defects: 1) The workload is large, and a large number of formwork and scaffolding erection operations are required, which requires a large amount of labor, high manual coordination, and high operational requirements; 2) The layout requirements are high, and high-precision control of the quality of formwork and scaffolding erection is required, which requires high operational and technical levels of the labor force; 3) The construction efficiency is low, and the formwork and scaffolding need to be cured after erection and pouring of concrete before the formwork can be removed, and the construction period is relatively long; 4) The quality of civilized construction is poor, it is not energy-saving and environmentally friendly, and a large amount of construction waste is generated during the construction process, and the site is dirty and messy.

[0004] Another method is to use prefabricated components produced in the factory and then transported to the site. The gantry crane is located on the ground, and the components are lifted one by one to the foundation pit, and then manually coordinated for installation and construction.

[0005] However, this method has the following defects: 1) There are great safety hazards. In geologically weak areas, in order to ensure the stability of foundation pit excavation, multiple groups of horizontal steel pipe supports need to be set up in the foundation pit. Generally, the spacing is small and the density is high. It is easy for components to collide with the steel supports during hoisting, causing the steel supports to be damaged or even the foundation pit to collapse. It requires extremely high technical level of hoisting equipment and hoisting personnel; 2) Construction efficiency is low and construction is inconvenient. Prefabricated components need to be hoisted back and forth many times. The components directly below the steel support need to be replaced with hoists and hoisted a second time before they can be put into place. The construction difficulty leads to low construction efficiency and greatly extended construction period; 3) The labor volume is large. Because it relies entirely on manual labor and gantry crane lifting, each component requires human assistance when it is in place, which requires a lot of labor; 4) Standardized operation cannot be achieved. Due to the limitation of the work site, there are many horizontal steel supports in the foundation pit. Using only hoisting machinery on the ground cannot meet the hoisting needs of all prefabricated components, which does not conform to the concept of standardized operation. Summary of the Invention

[0006] The present invention aims to provide an assembly equipment for superimposed prefabricated underground stations in urban rail transit projects, which has high construction efficiency and requires few templates for superimposed assembly. It solves the problems of traditional urban rail transit project underground station construction requiring a large amount of labor, high manual coordination, high operational requirements, low construction efficiency, poor civilized construction quality, high safety risks, and inability to achieve standardized operations.
