Construction method for open excavation assembly monolithic structure subway station using pile-strut bracing system

Abstract

The invention discloses a construction method for an open excavation assembly monolithic structure subway station using a pile-strut bracing system. The demand for labor force and the using requirement for on-site building circulating materials in traditional subway station construction can be lowered to the utmost extent, and wet construction work at the construction site can be greatly reduced. Flying dust and noise pollution at the construction site are reduced, and burdens to the surrounding traffic environment are reduced as well. The influence on the surrounding environment of the construction site is lowered. The novel component bracing system is adopted at the construction site, and therefore the degree of mechanization in the construction process is improved, and the demand for labor force by engineering is lowered. Moreover, the integral construction quality of associated works can be improved obviously by the adoption of plenty of prefabricated parts.

Description

technical field [0001] The invention relates to a construction method for a subway station with an open-cut assembly integral structure using a pile support system, and belongs to the field of building construction methods. Background technique [0002] The main structure of the conventional subway open-cut station is constructed by cast-in-place concrete. This construction method always has dust, noise and other pollution. The transportation of related materials such as concrete has a heavy burden on the traffic environment around the construction site. The demand for materials is high, the degree of mechanization of unit projects is low, and the demand for on-site labor is high, and some common quality problems of cast-in-place concrete such as honeycomb, pitted surface, cracks, holes, rotten edges, and rotten roots are common. Contents of the invention [0003] In order to solve the above problems, the present invention is achieved through the following technical soluti...
