Embodiment 1

[0048] Take the construction of an underground garage in a place with a narrow road and a large traffic volume, such as a railway station, as an example, the first scheme is adopted for construction:

[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) Section C is closed, surrounded by retaining structures and pavement barriers, and traffic is diverted. Before excavation of the surface soil, two rows of pile foundation construction and steel lattice column construction are carried out. For the construction of Section C, the surface soil is excavated. Make the top plate 1 of section C; connect the top plate 1 of section C with two rows of steel lattice columns to form a reinforced concrete bridge;

[0051] (3) Restore the pipeline, backfill the soil of section C, restore traffic, construct section A, carry out steel sheet pile or bored pile construction, and use the surrounding beam to form the...

Embodiment 2

[0057] Take the construction in a place with wide roads and small traffic volume as an example, adopt the second construction plan:

[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) Section C is closed, surrounded by retaining structures and pavement barriers, and traffic is diverted. Before excavation of the surface soil, two rows of pile foundation construction and steel lattice column construction are carried out. For the construction of Section C, the surface soil is excavated. Make the top plate 1 of section C; connect the top plate 1 of section C with two rows of steel lattice columns to form a reinforced concrete bridge;

[0060] (3) Restore pipelines, backfill section C earthwork, restore traffic, construct sections A and B at the same time, carry out steel sheet pile or bored pile construction, and make surrounding beams to form a foundation pit retaining structure, and then pile fo...

Abstract

The invention discloses an underground engineering construction method for road traffic, which comprises the following steps: (1) dividing the construction ground into three sections, namely the middle section C and sections A and B on both sides; (2) closing section C, For the construction of section C, excavate the surface earthwork to make the roof of section C; (3) backfill the earthwork of section C, and construct section A, excavate the surface earthwork to the base of the floor to make the floor of section A; (4) make the wallboard of section A; (5) Make the roof of Section A; (6) Backfill the earthwork of Section A, construct Section B, excavate the surface earthwork to the base of the base plate, and make the floor of Section B and Section C; make the wallboard of Section B; make the roof of Section B; (7) ) to backfill the earthwork of section B.

Description

Technical field [0001] The invention relates to a construction technology, in particular to a construction method of an underground project for road passage. Background technique [0002] Domestic urban development is increasingly facing problems such as land shortage, traffic congestion, environmental pollution, energy shortage, and fragile disaster prevention. The urban space expansion method is shifting from “above ground” to “three-dimensional”. More and more municipal and civil engineering projects are developing underground, and a large number of large underground buildings have been built. However, the development sites of underground buildings are often located in the center of the city, and the road closure during the construction period puts considerable pressure on traffic. Especially when there are no surrounding roads for vehicles to bypass, road closure construction will cause urban traffic functions. Paralysis. [0003] The current common methods of underground eng...
