Problems solved by technology

[0002] Existing underground overpasses or passages often adopt bridge-span structure or frame-culvert structure. Bridge-span structure is not conducive to the passage of large-diameter pipelines, and generally cannot be covered with soil for greening. There are also water leakage at expansion joints and single structural forms. Insufficient; the frame culvert structure requires excavation of the foundation pit under the floor, and then the construction is carried out sequentially, the floor-side wall-roof, the impact cycle on the ground traffic is long, and the relocation of municipal pipelines is small and difficult
[0003] How to provide a new semi-inverted underground structure and its construction method to solve the technical problems of construction joint leakage and long-term impact on ground traffic in existing construction has become one of the issues that technicians need to solve

Embodiment 1

[0023] Depend on figure 1 and figure 2 As shown, a kind of semi-reversed underground structure for underground road of the present invention comprises roof 1, enclosure pile 3, base plate 4, column pile 5, side wall 6, reinforced concrete column 7 and section steel column 8, described The two ends of the roof 1 are provided with end supports 101, and the middle is provided with a middle support 102. The enclosure piles 3 are arranged at the bottom of the roof 1, and the enclosure piles 3 are fixedly connected to the end supports 101. The reinforced concrete column 7 is arranged at the bottom of the roof 1, and the reinforced concrete column 7 is fixedly connected to the middle support 102, and the inside of the reinforced concrete column 7 is provided with a steel column 8; the bottom of the reinforced concrete column 7 Insert into upright stake 5.

[0024] The ends of both sides below the top plate 1 are reserved for connecting steel bars.

[0025] The profiled steel colu...

Embodiment 2

[0030] A kind of construction method of the semi-reversed underground structure that is used for underground road of the present invention, comprises the following steps:

[0031] (1) Excavating from the ground to the excavation surface 9 for the first time, the first excavation surface 9 is arranged below the bottom surface of the roof 1;

[0032] (2) Construct enclosure piles 3 at 9 places of the first excavation surface;

[0033] (3) install column pile 5 and reinforced concrete column 7 at the excavation place;

[0034] (4) On the excavation surface 9 for the first time, the roof slab 1 is poured in vertical form;

[0035] (5) After the roof 1 reaches the design strength, the formwork is removed, and the earth-covering structure 2 is laid on the top of the roof 1, and the municipal pipeline is laid at the same time, and the road construction is completed;

[0036] (6) Excavate the earth from the outside to the inside and from top to bottom under the top plate 1, and exca...

Abstract

The invention discloses a semi-reversed underground structure for an underground road and a construction method thereof. The semi-reversed underground structure comprises a crown plate, fender posts,a base plate, a vertical column post, side walls, a reinforced concrete vertical column and section steel vertical columns, wherein end supports are arranged at the two ends of the crown plate; a middle support is arranged in the middle of the crown plate; the fender posts are arranged at the bottom of the crown plate and are fixedly connected to the end supports; the reinforced concrete verticalcolumn is arranged at the bottom of the crown plate and is fixedly connected to the middle support; the section steel vertical columns are arranged in the reinforced concrete vertical column; and thebottom of the reinforced concrete vertical column is inserted in the vertical column post. The semi-reversed underground structure has a simple structural form, is fast in a construction method and does not affect ground transportation.

Description

technical field [0001] The invention relates to the technical field of underpasses for underpasses, in particular to a semi-reversed underground structure for underground roads and a construction method thereof. Background technique [0002] Existing underground overpasses or passages often adopt bridge-span structure or frame-culvert structure. Bridge-span structure is not conducive to the passage of large-diameter pipelines, and generally cannot be covered with soil for greening. There are also water leakage at expansion joints and single structural forms. Insufficient; the frame culvert structure requires the foundation pit to be excavated under the floor, and then the construction is carried out sequentially, the floor-side wall-roof, the impact cycle on the ground traffic is long, and the relocation of municipal pipelines is small and difficult. [0003] How to provide a new semi-inverted underground structure and its construction method to solve the technical problems ...
