Abstract

The invention discloses a method for constructing a multi-functional metro interchange station complex, which comprises the steps of: performing high-pressure cement grouting on a foundation within design scope; construction of an underground reinforced concrete diaphragm wall; construction of a steel reinforced concrete underground grouting pile group; construction of well spacing pattern double prestressed steel fiber type ground structure floors; dryness of moisture in a soil body by stages; construction of a first underground floor; construction of a second underground floor; construction of an overhead platform metro shield tunnel, a bridge and an overhead platform; construction of a third underground floor; construction of a bottom platform metro shield tunnel, a bridge and a bottom platform; earthwork excavation under the bottom bridge and construction of column facing of the steel reinforced concrete grouting pile group; construction of steel reinforced concrete of a buttress type annular ground beam and steel reinforced concrete of a bottom inverted arch bottom slab; construction of bottom platform and overhead platform rails and the platforms; construction of a steel reinforced concrete light shaft and a steel reinforced concrete elevator shaft; construction of a ground floor; construction of a first floor; and construction of various pipelines, and installation and debugging of various equipment. The method has the advantages of less investment on the construction of metro interchange stations, short construction period, small construction quantity, high construction efficiency, and social resource economization.

Description

technical field [0001] The invention belongs to the technical field of underground engineering structures, and in particular relates to a method for constructing a multifunctional subway transfer station complex in a modern city. Background technique [0002] With the continuous improvement of the level of social urbanization in our country, the scale of cities is expanding day by day, and the scale of urban infrastructure is becoming larger, and the integration of its functions is inevitable to meet the development needs of the society. The patent No. is 200410060443.6, and the patent titled "method for constructing a subway station" relates to a method for constructing a single-line subway station, but does not relate to a method for constructing a subway station at the intersection of two subway stations. Traditional subway station construction methods require large investment, long cycle time, poor working conditions and low efficiency. Contents of the invention [00...
