Description

Technical Field

[0001] This utility model relates to the field of pipe gallery, and in particular to a pipe gallery connection structure and a pipe gallery. Background Technology

[0002] Utility tunnels, also known as underground utility tunnels or integrated utility corridors, are a modern and intensive form of infrastructure that centrally houses two or more urban engineering pipelines within the same space. These pipelines include, but are not limited to, water supply, drainage, electricity, communications, gas, and heating. By constructing utility tunnels, unified planning, design, construction, and management of various municipal pipelines can be achieved, effectively solving problems such as difficult pipeline maintenance and frequent road excavation under traditional direct burial methods.

[0003] The applicant's earlier patent application, Chinese Patent Publication No. CN217782143U, discloses a novel underground space structure that eliminates the need for closing and disassembling the outer formwork, and allows for convenient and quick assembly and disassembly of the inner formwork, thus enabling fast construction and a short construction period.

[0004] However, the applicant discovered that during the actual construction process on site, adjacent segments were connected by welding expansion joints, requiring the excavation of separate working trenches. Welders would enter the working trenches to weld the outer surface of the steel shell of the segment to the outer edge of the expansion joint, and then backfill the working trenches after welding was completed. Meanwhile, the inside of the segment provided space for welding operations between the inner surface of the steel shell and the inner edge of the expansion joint. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing technologies require separate trenches to be dug for welding adjacent pipe gallery segments together with expansion joints. Welders then enter the trenches to weld the outer surface of the steel shell of the segments to the outer edge of the expansion joints, and the trenches are backfilled after welding. This presents a pipe gallery connection structure and a pipe gallery.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In the first aspect, this utility model provides a pipe gallery connection structure, wherein the end of the pipe gallery segment is provided with a shim block, and there is a gap between adjacent pipe gallery segments and they are connected by a half joint. The half joint includes an outwardly convex arc surface and a straight surface connected to the arc surface. The arc surface is located in the gap, and the straight surface overlaps the shim block and is connected by bolts.

[0008] The utility model describes a pipe gallery connection structure that, by setting up the shim block, raises the connection position between the half-joint and the end of the pipe gallery segment, allowing the half-joint to be installed without protruding from the surface of the pipe gallery segment. This eliminates the need for excavating additional installation trenches for the half-joint installation. Furthermore, the half-joint and the shim block are connected by bolts, allowing operation only within the pipe gallery segment, eliminating the need for external connection work and thus eliminating the need for excavating work trenches. This pipe gallery connection structure is simple, convenient to use, and effective.

[0009] As a preferred technical solution of this utility model, a sealing gasket is provided between the shim block and the half joint.

[0010] As a preferred technical solution of this utility model, the outer wall of the half-joint is connected with a first protective layer.

[0011] As a preferred technical solution of this utility model, the pipe gallery segment includes a steel structure layer and a concrete layer, and the concrete layer is connected to the inner wall of the steel structure layer.

[0012] As a further preferred technical solution of this utility model, the steel structure layer includes a straight steel plate and a corrugated steel plate, the corrugated steel plate is connected to the inner wall of the straight steel plate, and the concrete layer is connected to the inner wall of the straight steel plate and covers the corrugated steel plate.

[0013] This structural design, utilizing the ductility and elasticity of the corrugated steel plate, results in excellent overall seismic performance of the pipe gallery segment structure.

[0014] As a further preferred technical solution of this utility model, the straight steel plate at the end of the pipe gallery segment extends beyond the corrugated steel plate and the concrete layer, and the shim block is provided on the inner side of the extended straight steel plate.

[0015] As a further preferred technical solution of this utility model, the outer wall of the pipe gallery segment is connected with a second protective layer.

[0016] As a further preferred technical solution of this utility model, the second protective layer is wrapped around the top of the raised block.

[0017] As a further preferred technical solution of this utility model, the first protective layer and the second protective layer are respectively waterproof board or waterproof coating.

[0018] Secondly, this utility model also provides a pipe gallery, including pipe gallery segments, wherein adjacent pipe gallery segments are connected by a pipe gallery connection structure as described in any of the above.

[0019] The utility tunnel of this invention, by setting the shim block, raises the connection position between the half-joint and the end of the utility tunnel segment, so that the half-joint does not protrude from the surface of the utility tunnel segment. Therefore, the installation of the half-joint does not require the excavation of additional installation trenches. At the same time, the half-joint and the shim block are connected by bolts, allowing operation only within the utility tunnel segment without the need for external connection operations, and thus eliminating the need for excavation of work trenches. This utility tunnel has a simple structure, is easy to construct, and has good results.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The utility model discloses a pipe gallery connection structure. By setting the shim block, the connection position between the half joint and the end of the pipe gallery segment is raised, so that the half joint does not protrude from the surface of the pipe gallery segment. Therefore, the installation of the half joint does not require the excavation of additional installation trenches. At the same time, the half joint and the shim block are connected by bolts, so the operation can be carried out only within the pipe gallery segment without external connection operations, and therefore no work trenches need to be excavated. This pipe gallery connection structure is simple in structure, convenient to use, and has good effect.

[0022] 2. The utility model describes a pipe gallery where, by setting the shim block, the connection position between the half-joint and the end of the pipe gallery segment is raised, so that the half-joint does not protrude from the surface of the pipe gallery segment. Therefore, the installation of the half-joint does not require the excavation of additional installation trenches. At the same time, the half-joint and the shim block are connected by bolts, allowing operation only within the pipe gallery segment without external connection work, and thus eliminating the need to excavate work trenches. This pipe gallery has a simple structure, is easy to construct, and has good results. Attached Figure Description

[0039] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0040] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0042] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0043] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0044] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0045] In related technologies, adjacent pipe rack segments are connected by welding expansion joints. This requires digging a separate working trench, having welders enter the trench to weld the outer surface of the segment's steel shell to the outer edge of the expansion joint, and then backfilling the trench after welding. This process is cumbersome, and the expansion joints protrude from the segment surface, making installation inconvenient. Therefore, the technical solution of this application was developed. The following section discusses... Figures 1 to 5 To elaborate.

[0046] Example 1

[0047] like Figures 1 to 5 As shown, the utility model provides a pipe gallery connection structure, which includes a raised block 6, a split joint 9, and a first protective layer 10.

[0048] Among them, such as Figures 1 to 3 As shown, the pipe gallery segment 1 includes a steel structure layer and a concrete layer 4. The concrete layer 4 is connected to the inner wall of the steel structure layer. The steel structure layer is a precast component, and the concrete layer 4 is a cast-in-place component. The steel structure layer also serves as the outer mold for forming the concrete layer 4.

[0049] In some alternative implementations, such as Figures 1 to 3 As shown, the steel structure layer includes a straight steel plate 2 and a corrugated steel plate 3. The corrugated steel plate 3 is connected to the inner wall of the straight steel plate 2, and the concrete layer 4 is connected to the inner wall of the straight steel plate 2 and covers the corrugated steel plate 3. With this structural arrangement, the corrugated steel plate 3 has a certain degree of ductility and elasticity, which makes the overall seismic performance of the pipe gallery segment 1 excellent.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, the straight steel plate 2 at the end of the pipe gallery segment 1 extends beyond the corrugated steel plate 3 and the concrete layer 4. The raised block 6 is provided on the inner side of the extended straight steel plate 2. There is a gap between adjacent pipe gallery segments 1 and they are connected by the half-joint 9. The half-joint 9 includes an outwardly convex arc surface and a straight surface connected to the arc surface. The arc surface is located in the gap, and the straight surface overlaps the raised block 6. A sealing gasket 7 is provided between the raised block 6 and the straight surface. The outer wall of the half-joint 9 is connected to the first protective layer 10. The first protective layer 10 corresponding to the straight surface is located between the straight surface and the sealing gasket 7. The half-joint 9 and the raised block 6 are connected by bolts 8. The bolts 8 pass through the straight surface, the first protective layer 10, and the sealing gasket 7 in sequence and are locked onto the raised block 6.

[0051] like Figures 1 to 3 As shown, the outer wall of the pipe gallery segment 1 is connected to a second protective layer 5, such as... Figure 4 and Figure 5 As shown, the second protective layer 5 wraps around the top of the raised block 6.

[0052] In some optional embodiments, the first protective layer 10 and the second protective layer 5 are respectively waterproof sheets or waterproof coatings. The waterproof sheets are made of PVC or PE boards with a thickness of 5mm-6mm, and the joints are hot-melt welded. When using PVC or PE boards for covering, the outer surface of the steel structure layer is shot-blasted for rust removal and coated with two coats of anti-rust paint. The waterproof sheets are then adhered to the outer surface of the steel structure layer and the outer surface of the split joint 9. The waterproof coating is a polyurea coating. Before applying the polyurea coating, the outer surface of the steel structure layer is shot-blasted for rust removal. The polyurea coating can be applied by spraying and has a thickness of 5mm. This structure results in high strength and good corrosion resistance for the pipe gallery, making it corrosion-resistant and long-lasting.

[0053] The pipe rack connection structure described in this embodiment raises the connection position between the split joint 9 and the end of the pipe rack segment 1 by setting the shim block 6. This allows the split joint 9 to be installed without protruding from the surface of the pipe rack segment 1, thus eliminating the need to excavate additional installation trenches for the installation of the split joint 9. Furthermore, the split joint 9 and the shim block 6 are connected by bolts 8, allowing operation only within the pipe rack segment 1 without external connection work, and thus eliminating the need for excavation of work trenches. This pipe rack connection structure is simple, easy to use, and effective.

[0054] Example 2

[0055] like Figures 1 to 5 As shown, the utility model provides a utility tunnel, which includes a utility tunnel segment 1, and adjacent utility tunnel segments 1 are connected by a utility tunnel connection structure as described in Embodiment 1.

[0056] The pipe gallery described in this embodiment raises the connection position between the split joint 9 and the end of the pipe gallery segment 1 by setting the shim block 6, so that the split joint 9 does not protrude from the surface of the pipe gallery segment 1. Therefore, the installation of the split joint 9 does not require the excavation of additional installation trenches. At the same time, the split joint 9 and the shim block 6 are connected by the bolts 8, so the operation can be carried out only within the pipe gallery segment 1 without the need for external connection operations, and thus no need to excavate operation trenches. The pipe gallery has a simple structure, is easy to construct, and has good results.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
