Construction method of rail traffic column-free station in areas with dense underground pipelines

Abstract

The invention discloses a construction method of a rail traffic column-free station in areas with dense underground pipelines. By arranging guard piles, separation piles and temporary vertical columns, construction of an underground station is divided into two individual operation blocks, the influence of construction on existing pipelines can be reduced, and the risk and difficulty of station construction are lowered; pouring of the top plate of the column-free station and transferring of load borne are facilitated through the temporary vertical columns, and meanwhile the upper area can further provide space for containing the municipal underground pipelines, so that construction of the station body structure is facilitated. Furthermore, the problem that the underground pipelines have noplace to be replaced during excavation of an underground station foundation ditch and pouring of the station body can be avoided through transfer of the pipelines, and thus the municipal pipelines areprotected advantageously. According to the construction method of the rail traffic column-free station in the areas with the dense underground pipelines, the prominent problems that the disturbance of the underground pipelines are lowered through construction of the station, and transferring arrangement is difficult during the period of construction of the free-column station are solved, construction of the column-free station body structure is facilitated, and advantages that the station structure is simple, the construction technology is small, the construction difficulty is small, the costis relatively low, and the using range is wide are achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a method for constructing a rail transit column-free station in an area where underground pipelines are densely populated. Background technique [0002] Urban rail transit represented by subway plays a key role in urban passenger transport. An important sign of whether a city has entered modernization is whether urban rail transit represented by subways and light rails has been built. In order to alleviate the pressure of urban passenger flow and provide urban residents with a fast, safe and comfortable travel mode, urban rail transit lines are often set along the main passenger flow direction or the main road direction of the city. Based on the analysis of the current situation of my country's urban rail transit construction, stations in subway lines are generally located in areas with dense buildings or large passenger flow in the city. In these areas, in ord...
