Embodiment 1

[0048] Taking the construction of underground garages in places with narrow roads and large traffic volumes, such as railway stations, as an example, the first construction method is adopted:

[0049] (1) Divide the construction ground into three sections, namely, section C in the middle and sections A and B on both sides

[0050] (2) Close Section C, set up enclosure structures and road fences around, and divert traffic. Before excavating the surface soil, carry out two rows of pile foundation construction and steel lattice column construction, and excavate the surface soil for Section C construction. Make the roof 1 of section C; the roof 1 of section C is connected with two rows of steel lattice columns to form a reinforced concrete bridge;

[0051] (3) Restore the pipeline, backfill the earthwork of section C, restore traffic, construct steel sheet piles or bored piles for section A, and make surrounding beams to form the enclosure structure of the foundation pit, and then...

Embodiment 2

[0057] Taking the construction in places with wide roads and small traffic flow as an example, the second scheme is used for construction:

[0058] (1) Divide the construction ground into three sections, namely, section C in the middle and sections A and B on both sides

[0059] (2) Close Section C, set up enclosure structures and road fences around, and divert traffic. Before excavating the surface soil, carry out two rows of pile foundation construction and steel lattice column construction, and excavate the surface soil for Section C construction. Make the roof 1 of section C; the roof 1 of section C is connected with two rows of steel lattice columns to form a reinforced concrete bridge;

[0060] (3) Restore the pipeline, backfill the earthwork of section C, restore traffic, construct sections A and B at the same time, construct steel sheet piles or bored piles, and make surrounding beams to form the enclosure structure of the foundation pit, and then pile foundation constru...

Abstract

The invention discloses a road passage underground project construction method which includes the following steps: (1) dividing a construction ground into three sections, namely an A section on one side, a B section on the other side and a C section in the middle, (2) closing the C section, constructing the C section, excavating earth in the surface layer, and making a roof plate of the C section, (3) backfilling the earth of the C section, constructing the A section, excavating earth in the surface layer to a bottom plate base layer, and making a base plate of the A section, (4) making wall plates of the A section, (5) making a roof plate of the A section, (6) backfilling the A section with the earth, constructing the B section, excavating earth in the surface layer to a bottom plate base layer, making a base plate of the B section and a base plate of the C section, making wall plates of the B section, and making a roof plate of the B section, and (7) backfilling the B section with the earth.

Description

technical field [0001] The invention relates to a construction technology, in particular to an underground engineering construction method for road passage. Background technique [0002] Domestic urban development is increasingly facing problems such as land shortage, traffic congestion, environmental pollution, energy shortage, and vulnerability to disaster prevention. The way of urban space expansion is shifting from "ground" to "three-dimensional". More and more municipal projects and civil projects choose to develop underground, and a large number of large underground buildings have been newly built. However, the development site of underground buildings is often located in the center of the city. During the construction period, the closed road will put a lot of pressure on the traffic, especially when there are no surrounding roads for vehicles to detour, the road closed construction will cause urban traffic function of paralysis. [0003] The current common methods o...
