Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a concrete reinforcement support structure for underground utility tunnels. Background Technology

[0002] Underground utility tunnels, also known as integrated underground utility tunnels, are centralized municipal infrastructure built underground in cities to centrally lay various pipelines such as electricity, communications, gas, water supply, and drainage. Their core function is to avoid repeated road excavation, improve pipeline maintenance efficiency, save urban land, and reserve space for future urban development through unified planning, construction, and management. Underground utility tunnels are typically constructed of reinforced concrete, with spans designed according to pipeline layout requirements. The interior must provide sufficient space for personnel passage, equipment installation, and maintenance.

[0003] In existing technologies, the stress on pipelines increases when heavy transportation infrastructure is added to the surface, such as highways and rail transit; deep foundation pits are constructed nearby; and when utility tunnels have been in service for more than 30 years or are in highly corrosive environments, structural defects may occur, requiring preventative reinforcement. Existing reinforcement support structures mostly use single materials or simple combination support forms, such as pure steel structures or pure concrete structures, lacking an organic combination of steel structure and reinforced concrete. This leads to uneven material stress, local deformation, and even fracture under complex loads, making it difficult to meet the high-strength and high-durability support requirements for long-term operation of underground utility tunnels. At the same time, traditional support structures lack effective lateral tie mechanisms when dealing with the coordinated support of adjacent utility tunnel sections or multiple sections. When uneven settlement occurs in the tunnel foundation or when affected by the stress of the surrounding soil, problems such as misalignment of the utility tunnel body may occur. Therefore, it is necessary to propose a concrete reinforcement support structure for underground utility tunnels to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a concrete reinforcement and support structure for underground utility tunnels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete reinforcement support structure for an underground utility tunnel includes two concrete utility tunnel bodies spaced apart. Each concrete utility tunnel body has two supporting steel structures inside. The structure also includes a support assembly for supporting the concrete utility tunnel bodies. The support assembly is located inside the concrete utility tunnel bodies and includes: several vertical main reinforcement bars, all located inside the supporting steel structures, spaced apart and arranged in a rectangular pattern; several vertical stirrups inside the supporting steel structures, with the vertical main reinforcement bars and stirrups fixed together by ties; several first fixing holes on one side of the supporting steel structures; several connecting steel structures between the two supporting steel structures; several diagonal tie bars inside the connecting steel structures, with hook-shaped ends that hook the vertical main reinforcement bars; and several transverse stirrups movably sleeved around the diagonal tie bars, with the transverse stirrups and diagonal tie bars fixed together by ties.

[0007] As a further embodiment of this utility model, a plurality of first threaded columns are fixedly installed on one side of the supporting steel structure, and a plurality of connecting holes are respectively opened on both sides of the connecting steel structure. The connecting holes are movably sleeved with the first threaded columns, and a first nut is threadedly connected to the outer circular wall surface of the first threaded column.

[0008] As a further embodiment of this utility model, the supporting steel structure is provided with an inner supporting tube.

[0009] As a further embodiment of this utility model, a grouting port is provided on one side of the supporting steel structure.

[0010] As a further embodiment of this utility model, two second threaded columns are fixedly installed on one side of the supporting steel structure, a baffle is provided on one side of the supporting steel structure, and two threaded holes are opened on one side of the baffle. The threaded holes are movably sleeved with the second threaded columns, and a second nut is threadedly connected to the outer circular wall surface of the second threaded column.

[0011] As a further embodiment of this utility model, a connecting plate is fixedly installed on the top and bottom surfaces of the supporting steel structure, and the top surface of the connecting plate is provided with a plurality of mounting holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using the concrete pipe gallery body, supporting steel structure, vertical main reinforcement, vertical stirrups, and connecting steel structure in a coordinated manner, the concrete pipe gallery body can be supported. The combination of concrete, steel reinforcement, and steel structure achieves multi-material support. The reinforced concrete is not easily corroded or damaged, effectively providing high-strength and high-durability support and ensuring the support effect. At the same time, through several horizontally inclined diagonal braces and horizontal stirrups, the connecting steel structure provides lateral tension. When the pipe gallery foundation experiences uneven settlement or is affected by the stress of the surrounding soil, it avoids problems such as staggered settlement between two concrete pipe gallery bodies, effectively ensuring the support effect.

Two supporting steel structures 2 are installed inside each concrete utility tunnel body 1. The structure also includes a support assembly for supporting the concrete utility tunnel body 1. The support assembly is located inside the concrete utility tunnel body 1 and includes several vertical main reinforcement bars 3, all of which are located inside the supporting steel structures 2. The vertical main reinforcement bars 3 are spaced apart and arranged in a rectangular pattern. Several vertical stirrups 4 are installed inside the supporting steel structures 2. The vertical main reinforcement bars 3 and the vertical stirrups 4 are fixed together by tying wires. Several first fixing holes 6 are opened on one side of the supporting steel structures 2. Several connecting steel structures 5 are installed between the two supporting steel structures 2. Several diagonal tie bars 7 are installed inside the connecting steel structures 5. The ends of the diagonal tie bars 7 are hook-shaped and hook onto the vertical main reinforcement bars 3. Several transverse stirrups 8 are movably sleeved on the outside of the diagonal tie bars 7. The transverse stirrups 8 and the diagonal tie bars 7 are fixed together by tying wires.

[0025] In this embodiment, several first threaded posts 10 are fixedly installed on one side of the supporting steel structure 2. Several connecting holes 9 are respectively opened on both sides of the connecting steel structure 5. The connecting holes 9 are movably sleeved with the first threaded posts 10. The outer circular wall surface of the first threaded post 10 is threadedly connected with a first nut 11. The supporting steel structure 2 is provided with a supporting inner tube 17. A grouting port 16 is opened on one side of the supporting steel structure 2. Two second threaded posts 13 are fixedly installed on one side of the supporting steel structure 2. A baffle 12 is provided on one side of the supporting steel structure 2. Two threaded holes 15 are opened on one side of the baffle 12. The threaded holes 15 are movably sleeved with the second threaded posts 13. The outer circular wall surface of the second threaded post 13 is threadedly connected with a second nut 14. A connecting plate 18 is fixedly installed on the top and bottom surfaces of the supporting steel structure 2. Several mounting holes 19 are opened on the top surface of the connecting plate 18.

[0026] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0027] With the concrete pipe gallery body 1 in place, when users support the interior of the concrete pipe gallery body 1, the support position is set according to the requirements. Then, the supporting steel structure 2 and the connecting steel structure 5 are placed as a whole at the location where support is needed. If necessary, holes or grooves can be drilled or slots can be cut at the installation location to embed the vertical main reinforcement 3 in the groove, or the vertical main reinforcement 3 can be anchored in other ways. Anchoring is an existing technology and will not be described in detail. Alternatively, the support can be used directly. Then, the interior of the supporting steel structure 2 and the connecting steel structure 5 can be grouted through the grouting port 16, and the interior of the supporting steel structure 2 and the connecting steel structure 5 can be uniformly filled with concrete by vibration equipment. It should be noted that the top of the grouting port 16 needs to be grouted to avoid the top not being able to fill with concrete. During production, the other sides of the concrete pipe gallery body 1 can be set with the concrete pipe gallery body 1 and other internal and external components according to actual needs. They are connected by the connecting steel structure 5 and other components to form a cross-shaped support, a T-shaped support, or an L-shaped support, further improving the support effect.

[0028] The supporting steel structure 2 can be fixed by inserting bolts into the mounting holes 19 and the mounting holes at the installation location. The baffle 12 can be fixed and the grouting port 16 can be sealed by connecting the threaded hole 15 to the second threaded post 13 and tightening the second nut 14. The supporting inner tube 17 can be selected for use to further improve the compressive strength of the structure.

[0029] Furthermore, by supporting the steel structure 2, connecting the steel structure 5, and vertical main reinforcement 3, the steel structure and reinforced concrete are combined to achieve multi-material support. The reinforced concrete is not easily corroded or damaged, effectively providing high-strength and high-durability support and ensuring the support effect. At the same time, by using several horizontally inclined tie bars 7 and horizontal stirrups 8 to pull the connecting steel structure 5 laterally, when the pipe gallery foundation experiences uneven settlement or is affected by the stress of the surrounding soil, it avoids problems such as staggered settlement between the two concrete pipe gallery bodies 1, effectively ensuring the support effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
