Problems solved by technology

[0003] However, for railway lines in soft soil areas, due to the limited space between two existing railways and the existing railways have been built and operated, the construction site, construction machinery and construction time of the new line are restricted to varying degrees. Moreover, the foundation reinforcement pile foundation construction of the new line also needs to ensure that it can reduce disturbance to the existing lines on both sides and prevent additional settlement and deformation of the existing lines. Therefore, the relevant pile foundation construction is difficult to meet the construction requirements

Abstract

The embodiment of the invention provides a spiral steel pile plate structure and a construction method. The spiral steel pile plate structure comprises a reinforced concrete bearing plate, a pluralityof spiral steel piles and a broken stone hardcore, and the multiple spiral steel piles are arranged at intervals. One ends of the multiple spiral steel piles are connected with the reinforced concrete bearing plate, and the ends, away from the reinforced concrete bearing plate, of the multiple spiral steel piles are fixed in a bearing layer; the broken stone hardcore is laid on the side, close tothe bearing layer, of the reinforced concrete bearing plate. According to the spiral steel pile plate structure and the construction method provided by the embodiment of the invention, land excavation or cement pouring is not needed; the construction disturbance is small, the influence on an existing railway can be reduced and additional settlement of the existing railway can be controlled, the spiral steel pile plate structure is small in working face, rapid in construction, high in pile forming speed, excellent in performance, good in stability and capable of well controlling settlement deformation of a newly-built railway roadbed.

Description

technical field [0001] The invention relates to the field of railway subgrade construction, in particular to a spiral steel pile-slab structure and a construction method. Background technique [0002] With the development of my country's economy, the railway construction is rapid, and some newly-built lines are affected by various factors, so the line position needs to be set between two existing railways. [0003] However, for railway lines in soft soil areas, due to the limited space between two existing railways and the existing railways have been built and operated, the construction site, construction machinery and construction time of the new line are restricted to varying degrees. Moreover, the foundation reinforcement pile foundation construction of the new line also needs to ensure that it can reduce disturbance to the existing lines on both sides and prevent additional settlement and deformation of the existing lines. Therefore, the relevant pile foundation construc...
