Description

Technical Field

[0002] In recent years, the development of prefabricated construction technology has provided new insights into pipeline corridor construction. Composite slabs, as a prefabricated component, have been widely used in the construction industry. Their advantages include: high construction efficiency, with prefabricated components produced in a fabrication plant, allowing for rapid on-site installation and shortened construction schedules; controlled quality, with mechanized, modular batch production in a back-end fabrication plant effectively ensuring component dimensional accuracy and reducing manual on-site construction errors; reduced on-site wet work time, accelerating construction progress; reduced turnover material input, saving costs; and significant environmental benefits, reducing noise, dust, and waste emissions on the construction site, facilitating safe and civilized construction control.

[0003] In urban utility corridor construction, composite slab construction has been successfully applied in some projects for roof slabs, improving construction efficiency and quality. However, the simultaneous use of composite structures for both wall panels and roof slabs in urban utility corridor construction still faces challenges. The mainstream approach currently relies on cast-in-place structures, which suffer from long construction periods, significant exposure to natural factors, reliance on the technical expertise of on-site construction personnel for quality control, the need for materials to be transported over long distances within the corridor, high labor costs, and significant investment in turnover materials.

The prefabricated wall panels 320 are fixedly connected to the cast-in-place bottom plate 100 by pouring concrete.

[0059] The cast-in-place structure 200 includes an integrally formed cast-in-place top portion 210 and two cast-in-place side portions 220. The cast-in-place side portions 220 are located at both ends of the multiple cast-in-place top portions 210 along the second direction D2. The cast-in-place side portions 220 are fixedly connected to the multiple prefabricated wall panels 320 by pouring concrete. The cast-in-place top portion 210 is located on top of the multiple prefabricated top panels 310. The cast-in-place top portion 210 is fixedly connected to the multiple prefabricated top panels 310 by pouring concrete.

[0060] A limiting assembly is set between two opposing prefabricated wall panels 320, and at least part of the components of the limiting assembly are detachably connected to the prefabricated wall panels 320.

[0061] In the composite wall panel structure tunnel provided in this embodiment, bottom plate steel bars 120 and a support structure 110 are embedded in the cast-in-place bottom plate 100. The bottom plate steel bars 120 enhance the tensile strength of the cast-in-place bottom plate 100, and the support structure 110 provides a rigid support foundation for the prefabricated wall panels 320, so that a uniform force system is formed at the bottom of the entire tunnel, and the anti-settlement ability is improved, thereby ensuring that the tunnel bottom maintains structural integrity when the foundation settles unevenly and avoiding cracking of the cast-in-place bottom plate 100; in addition, the prefabricated top plate 310 is arranged astride the top of the prefabricated wall panels 320, the cast-in-place top 210 of the cast-in-place structure 200 is connected to multiple prefabricated top plates 310, and the cast-in-place side parts 220 are connected to multiple prefabricated wall panels 320, forming a "prefabricated-cast-in-place" composite load-bearing system, thereby improving the overall rigidity of the tunnel, capable of withstanding the upper covering soil and ground loads, while enhancing the ability to resist lateral earth pressure, and achieving improved stability and bearing capacity of the tunnel.

[0062] In addition, multiple prefabricated component units 300 are arranged along the first direction D1, and each prefabricated component unit 300 includes a prefabricated top plate 310 and a prefabricated wall panel 320, which can be hoisted on site after prefabrication in the factory, reducing the workload of on-site pouring, thereby shortening the construction period and reducing the difficulty of on-site construction. At the same time, the standardized production of the prefabricated component units 300 can ensure the dimensional accuracy of the components; the limiting components arranged between the relative prefabricated wall panels 320 are used to fix the relative spacing and verticality of the two prefabricated wall panels 320 during the construction process, avoid position deviation during the installation of the prefabricated wall panels 320, ensure the accurate internal space dimensions of the pipe corridor, ensure the overall stability during the installation of the prefabricated wall panels 320, and prevent the wall from overturning during the installation process, thereby achieving improved construction efficiency and optimized precision of the pipe corridor.

[0063] In addition, adjacent prefabricated wall panels 320 are connected by connecting components 327 to form a transverse continuous structure, thereby enhancing the shear resistance and seismic performance of the pipeline corridor in the longitudinal direction, preventing cracks from occurring between adjacent prefabricated wall panels 220, and improving the overall durability of the structure. At the same time, the overall stability of the prefabricated wall panels 320 during installation is ensured, and the prefabricated wall panels 320 are prevented from overturning during the installation process; the one-piece connection between the cast-in-place top 210 and the cast-in-place side 220 can fill the gap between the prefabricated component units 300, thereby reducing the risk of water leakage at the joints, forming a closed waterproof system, which is suitable for underground humid environments and prolongs the service life of the pipeline corridor; thereby enhancing the integrity and durability of the pipeline corridor.

[0064] See also Figure 2 and Figure 3 In some embodiments, the prefabricated wall panel 320 is embedded with a plurality of hooking bars 301, first vertical bars 321 extending in the vertical direction, and first horizontal bars 322 arranged at intervals along the vertical direction, and the plurality of first horizontal bars 322 are connected to the first vertical bars 321 to form a grid structure; the cast-in-place side portion 220 is embedded with a plurality of second vertical bars 221 extending in the vertical direction and second horizontal bars 222 arranged at intervals along the vertical direction, and the plurality of second horizontal bars 222 are connected to the second vertical bars 221 to form a grid structure; one end of the hooking bar 301 is hooked with the first horizontal bar 322 and embedded in the prefabricated wall panel 320, and the other end of the hooking bar 301 is hooked with the second horizontal bar 222 and embedded in the cast-in-place side portion 220.

[0065] In this embodiment, a grid structure is formed between the first vertical rib 321 and the first horizontal rib 322 in the prefabricated wall panel 320, and between the second vertical rib 221 and the second horizontal rib 222 in the cast-in-place side portion 220, thereby enhancing the structural strength of the prefabricated wall panel 320 and the cast-in-place side portion 220. In specific implementation, multiple hooking bars 301 can be evenly distributed on the entire wall surface of the prefabricated wall panel 320, one end of the hooking bar 301 is hooked with the first horizontal rib 322 of the prefabricated wall panel 320 and embedded in the prefabricated wall panel 320, and the other end of the hooking bar 301 is hooked with the second vertical rib 221 of the cast-in-place side portion 220 and embedded in the cast-in-place side portion 220. This cross-anchoring method enables the prefabricated component unit 300 to form a firm "mechanical bite" with the cast-in-place structure 200, effectively transmitting tension and shear force, significantly improving the connection strength at the joints, avoiding cracks or detachment, and ensuring the overall stability of the tunnel structure.

[0068] In this embodiment, a grid structure is formed by the first transverse reinforcement 311 and the hook reinforcement 312, and the second transverse reinforcement 211 in the cast-in-place top 210 is connected to the hook reinforcement 312, thereby enhancing the continuity of the reinforcement between the prefabricated top plate 310 and the cast-in-place top 210, improving the overall bending and shear resistance of the top of the tunnel corridor, reducing the amount of on-site reinforcement processing and improving construction efficiency. At the same time, the grid reinforcement can suppress concrete cracks and ensure the uniformity of the protective layer, thereby enhancing the durability and impermeability of the tunnel corridor and realizing the coordinated force of the prefabricated and cast-in-place parts.

[0070] During specific implementation, steel bars are also provided in the corbel structure 330, which are connected with the steel bars in the prefabricated wall panel 320 to form a through reinforcement system. The steel bar arrangement of the corbel structure 330 is consistent with that of the conventional corbel, including main stress-bearing bars and stirrups, to ensure the bearing capacity and shear resistance of the corbel structure 330 when supporting the prefabricated top plate.

[0071] In this embodiment, the top surface of the corbel structure 330 provides direct support for the prefabricated top panel 310, which simplifies the installation process of the prefabricated top panel 310 and improves the positioning accuracy; at the same time, the prefabricated wall panel 320 and the corbel structure 330 are integrally formed, which enhances the connection strength between the corbel structure 330 and the prefabricated wall panel 320, reduces stress concentration problems, and improves the overall structural stability.

In this way, the angle hook 3271 can effectively transmit tension and shear force, and firmly connect adjacent prefabricated wall panels 320; the vertical plates of the L-shaped angle plates 3272 of adjacent prefabricated wall panels 320 are spot-welded, which further enhances the connection strength at the joints of adjacent prefabricated wall panels 320, so that multiple prefabricated wall panels 320 form a stable whole after splicing, thereby improving the ability of the pipeline corridor to resist external loads (such as soil pressure and ground vehicle loads), and ensuring the stability and safety of the pipeline corridor structure in long-term use. The angle hook 3271 and the L-shaped angle plate 3272 can be installed during the production stage of the prefabricated wall panel 320. During on-site construction, it is only necessary to spot-weld the L-shaped angle plates 3272 of adjacent prefabricated wall panels 320 for temporary support. The operation is simple and quick. This combination of prefabrication and on-site welding reduces the construction difficulty, shortens the construction period, and facilitates quality control by construction personnel, thereby improving construction efficiency.

[0078] See also Figure 2 and Figure 4 In some embodiments, a full-length edge protection angle steel 328 is provided on the bottom side edge of the prefabricated wall panel 320. The full-length edge protection angle steel 328 is used to protect the prefabricated wall during construction and installation to prevent the prefabricated wall panel 320 from being damaged during the installation process.

[0079] Figure 7 The structure diagram of the lifting ring in the embodiment of the present application is shown. In specific implementation, the lifting ring 400 is provided for the prefabricated wall panel 320 and the prefabricated top panel 310 to facilitate the lifting of the prefabricated wall panel 320 and the prefabricated top panel 310.

[0080] Figure 8 The diagram shows the structure of the pipe gallery with composite wall panels during construction in the embodiment of the present application. Figure 2 and Figure 8 Based on the same inventive concept, the present application also provides a construction method for a pipe gallery with a composite wall panel structure as provided in any of the above embodiments. The construction method comprises the following steps:

[0081] Step 1: Tie the bottom plate reinforcement 120 and arrange the support structure 110;

[0082] Step 2: Hoist the prefabricated wall panels 320 to the top of the cast-in-place base plate 100, with the bottom of the prefabricated wall panels 320 placed on the top of the support structure 110; the opposing prefabricated wall panels 320 are fixed by limiting assemblies, and adjacent prefabricated wall panels 320 are connected by connecting assemblies 327;

[0083] Step 3: Set up the formwork and pour concrete to form the cast-in-place base plate 100. After the cast-in-place base plate 100 solidifies and reaches the designed strength, the prefabricated wall panel 320 is fixed to the cast-in-place base plate 100.

[0084] Step 4: Install the prefabricated top panel 310 between the installed prefabricated wall panels 320;

[0085] Step 5: After the prefabricated wall panels 320 and the prefabricated top panels 310 are installed, steel bars are arranged at the joints between adjacent prefabricated component units 300;

[0086] Step 6: Set up the formwork, bury the steel bars of the cast-in-place structure 200, connect the pre-buried steel bars of the prefabricated component unit 300 with the steel bars of the cast-in-place structure 200, and form the cast-in-place structure 200 connected to the prefabricated component unit 300 by pouring concrete in situ;

[0087] Step 7: After the concrete solidifies, remove the formwork and limit components and carry out maintenance.

[0088] When implementing step 5, see Figure 8 , two first measure ribs 501 and a plurality of first joint treatment ribs 502 connected to the first measure ribs 501 are provided at the joints of the prefabricated wall panels 320, and the first measure ribs 501 extend along the vertical direction to the cast-in-place structure 200 in the next step (step six) and do not pass through the cast-in-place structure 200, and the plurality of first joint treatment ribs 502 are evenly arranged along the vertical direction, and the two ends of each first joint treatment rib 502 are respectively connected to the pre-buried hook bars 301 of the two adjacent prefabricated wall panels 320; two second measure ribs 503 and a plurality of second joint treatment ribs 504 are provided at the joints of the prefabricated top plate 310, and the second measure ribs 503 extend along the second direction D2, and the plurality of second joint treatment ribs 504 are provided. The second joint treatment bars 504 are evenly arranged along the second direction D2, and the two ends of each second joint treatment bar 504 are respectively connected to two second treatment bars 503; in this way, the adjacent prefabricated component units 300 are "rigidly connected" as a whole through the steel bars, so that the load can be transmitted to the entire structural system through the steel bars, avoiding excessive force on local components alone, and significantly improving the overall stiffness and coordinated deformation capacity of the structure; arranging steel bars at the joints can enhance the integrity and stiffness of the structure, optimize force transmission to improve bearing capacity, inhibit cracks, enhance crack resistance, improve seismic ductility and safety, improve durability, extend life, and ensure reliable connection and adapt to construction errors.

[0089] In the construction method of the composite wall panel structure pipeline corridor provided in this embodiment, the prefabricated wall panels 320 and the prefabricated top panels 310 are prefabricated in the factory and directly hoisted on site, reducing the workload of on-site pouring, thereby transferring part of the process to the factory, shortening the on-site construction time, and being suitable for municipal projects with tight construction schedules; the prefabricated wall panels 320 are abutted by the supporting structure 110, and after the concrete of the cast-in-place bottom plate 100 solidifies, the prefabricated wall panels 320 are fixedly connected to the cast-in-place bottom plate 100 to form a whole, and the synergistic effect of the embedded steel bars and the cast-in-place concrete is combined to enhance the structural integrity and shear resistance, thereby effectively improving the bearing capacity and seismic resistance of the pipeline corridor.

[0090] Furthermore, the high precision and controlled quality of the prefabricated component units 300 reduce the complexity of on-site formwork support and rebar binding. Standardized prefabricated components lower the technical barriers to construction, minimize human error, and ease on-site construction difficulties, ensuring consistent construction quality. Furthermore, factory prefabrication reduces on-site construction waste, dust, and noise pollution. The high reuse rate of prefabricated components reduces material waste, and the shortened construction period further saves costs such as labor and equipment rental. Furthermore, modular prefabricated components facilitate the adjustment of the corridor's size and functionality to meet diverse project requirements. The design of the limiter and connection components 327 facilitates component installation and disassembly, facilitating subsequent maintenance and renovation.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
