Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit bridge structure, and specifically relates to a structure for the joint construction of rail transit and municipal tunnels. Background Technology

[0002] In modern road design, the increasing number of vehicles often means that the number of roads on the ground cannot meet the traffic demand. Therefore, the construction of rail transit and tunnel systems is necessary to develop elevated and underground driving areas, increasing the driving space within the same available area. Due to planning, economic, and aesthetic factors, rail transit bridges and municipal tunnels sometimes cannot be completely avoided, requiring shared routes and joint construction. When rail transit bridges and municipal tunnels must share routes due to objective constraints (i.e., located in the same spatial corridor, possibly overlapping, parallel, or intersecting), a series of complex problems arise due to significant differences in their structural characteristics, load types, construction methods, and operational requirements.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a structure for the co-construction of rail transit and municipal tunnels, and to solve the problems mentioned in the background technology.

[0006] The tunnel assembly includes a combined municipal tunnel section, a municipal tunnel transition section, combined section pile foundation columns, and transition section pile foundation columns. A set of municipal tunnel transition sections are fixedly connected to both the front and rear sides of the combined municipal tunnel section. Several sets of transition section pile foundation columns are fixedly connected below the municipal tunnel transition sections. Several combined section pile foundation columns are fixedly connected below the combined municipal tunnel section.

[0007] As a preferred embodiment, a set of guardrails is fixedly connected to both the left and right sides above the box girder. A sound barrier for reducing sound transmission is fixedly connected to the end of the guardrail away from the center of the track assembly. The sound barrier set on the outside diffuses and blocks the sound of the track vehicle.

[0008] In a preferred embodiment, a contact wire is fixedly connected to one end of the guardrail near the center of the track assembly, and a set of track seats is fixedly connected to both the left and right sides above the box girder. A low-voltage cable trough is provided on the side of the track seat away from the center of the track assembly.

[0009] In a preferred embodiment, the track seat is provided with a high-voltage cable trough on the side near the center of the track assembly, and the first and second piers are fixedly installed above the combined section of the municipal tunnel. The cables in the track area are arranged in an orderly manner through the low-voltage cable trough and the high-voltage cable trough.

[0010] In a preferred embodiment, both the combined municipal tunnel section and the municipal tunnel transition section are composed of an upper top slab, a lower bottom slab, a right side web 1, and a left side web 2.

[0011] In a preferred embodiment, the pile foundation columns of the combined section and the pile foundation columns of the transition section are all uniformly distributed. The diameter and number of the pile foundation columns of the combined section are larger than those of the pile foundation columns of the transition section. The pile foundation columns of the combined section and the pile foundation columns of the transition section are located below the combined section and the transition section of the municipal tunnel to provide stable support at the bottom.

[0012] As a preferred embodiment, the connection between the combined municipal tunnel section and the transition section of the municipal tunnel serves as the boundary for the bridge abutment.

[0013] As a preferred embodiment, the lower outer sides of the first and second piers are provided with a design ground line area.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By adding track components and tunnel components, the track components are set above the tunnel components. The tunnel components are divided into a combined municipal tunnel section and a transition section, which are set alternately. Pier 1 and Pier 2 are set above the combined municipal tunnel section and are fixedly connected to the box girder in the track components through supports. In the construction of the track components and tunnel components, they are only co-constructed in the combined municipal tunnel section. The diameter and number of pile foundation columns set below the combined municipal tunnel section are larger than those in the transition section, providing enhanced stability support and solving the problem of the shared route between the rail transit bridge structure and the municipal tunnel structure.
