Description

Technical Field

[0001] This application belongs to the field of prefabricated building technology, specifically relating to a prefabricated integrated pipe gallery component and pipe gallery structure. Background Technology

[0002] Integrated utility tunnels are an important form of urban underground pipeline network facilities. By concentrating multiple pipelines in one tunnel, repeated road excavation can be effectively reduced, the utilization rate of above-ground and underground space can be improved, the utilization cost of urban underground space can be reduced, and pipeline maintenance and management can be facilitated.

[0003] However, existing precast integrated utility tunnel structures generally use cast-in-place reinforced concrete or monolithic precast reinforced concrete structures, and most precast tunnel segments are quite heavy, especially the 2-meter-long, double-compartment precast segments, which weigh close to 40 tons. The transportation and hoisting of these heavy precast segments place high demands on on-site roads and lifting equipment, making construction more difficult. Furthermore, the large size of individual precast segments further complicates transportation and installation.

[0004] Furthermore, the heavy weight of the precast segments and the limitations of the construction site often result in excessively short precast segment lengths, increasing the number of longitudinal joints and potentially increasing the risk of water seepage. Meanwhile, the waterproofing performance at the joints remains a challenge; poor sealing at the segment connections easily leads to water seepage, causing structural damage to the utility tunnel after long-term use.

[0005] Therefore, reducing the weight of individual prefabricated segments, simplifying the installation process, and effectively addressing the risk of water leakage at joints have always been challenging issues in the design and construction of integrated utility tunnels. To address this problem, this application proposes a prefabricated integrated utility tunnel component and tunnel structure. Utility Model Content

[0006] The purpose of this application is to provide a prefabricated integrated utility tunnel component and structure, which solves the problems of high difficulty in existing utility tunnel construction and poor waterproof performance.

[0007] The objective of this application is achieved through the following technical solution:

[0008] A prefabricated integrated utility tunnel component includes a first component and a second component. The first component includes a first joint, and the second component includes a second joint. The first joint or the second joint is provided with an outer blocking edge located on both sides and along the longitudinal direction. The first joint is provided with an inner blocking edge located between the two sides and along the longitudinal direction. Several positioning protrusions are arranged at intervals along the longitudinal direction on the inner blocking edge. The second joint is provided with several positioning pins arranged at intervals along the longitudinal direction between the two sides to form a row. Four adjacent positioning pins in two adjacent rows of positioning pins together form a raised positioning groove.

[0009] Furthermore, the first component is an upper component, and the second component is a lower component.

[0010] Furthermore, the first component, the first connector, the inner blocking edge, and the positioning protrusion are an integral structure, the second component, the second connector, and the positioning pin are an integral structure, and the outer blocking edge is an integral structure with the first connector, or the outer blocking edge is an integral structure with the second connector.

[0011] Furthermore, the outer blocking edge is a cuboid structure, and the inner blocking edge is a cuboid structure.

[0012] Furthermore, the internal barrier is provided along one line and arranged along the centerline of the first joint, and the positioning pins are provided in two rows and arranged symmetrically along the centerline.

[0013] Furthermore, the positioning protrusion and the positioning pin are both cylindrical structures.

[0014] Furthermore, a sealing ring is fitted onto the positioning pin.

[0015] Furthermore, the outer blocking edge is provided with a slurry inlet hole, and the first connector is provided with a slurry outlet hole that connects to the inner side of the outer blocking edge.

[0016] A prefabricated integrated utility tunnel structure includes the aforementioned prefabricated integrated utility tunnel components, with an outer blocking edge fitting a first joint or a second joint, an inner blocking edge fitting a second joint, a positioning protrusion inserted into a protrusion positioning slot, and grouting material poured and filled between the outer blocking edge and the inner blocking edge.

[0017] Furthermore, the first component and the second component form a single-compartment, double-compartment, or multi-compartment pipe gallery.

[0018] The beneficial effects of this application are:

[0019] 1. Reduce the weight of prefabricated segments: By dividing the prefabricated pipe gallery into multiple components in the upper and lower parts, the weight of each component is reduced, which greatly reduces the difficulty of transportation and hoisting, improves construction efficiency, and reduces the requirements for hoisting equipment.

[0020] 2. Simplified installation process: The modular slot joint design makes the installation process simpler. The upper and lower components are initially fixed by friction, saving a lot of labor and equipment resources.

[0021] 3. Enhanced structural stability: The upper and lower parts are connected by modular slot joints, and the joints are reinforced by grouting to prevent water seepage and improve the overall integrity and waterproof performance of the pipe gallery structure.

[0022] 4. Improved construction flexibility: Since the pipe gallery segments can be further subdivided according to actual needs, the structure is more flexible and can adapt to different construction environments and requirements. Whether it is a single-compartment pipe gallery or a multi-compartment pipe gallery, it can be effectively implemented.

[0023] 5. Reduce the risk of water seepage at joints: The grouting process effectively fills the gaps at the joints, enhancing the waterproof performance and preventing damage to the pipe gallery structure and maintenance difficulties caused by water seepage at the joints.

[0024] 6. Adaptable to complex environments: Because the prefabricated pipe gallery structure can be divided into multiple small sections, it is more flexible in installation and can adapt to different scene requirements. Whether it is a narrow space in the city or a complex underground pipe network environment, it can be effectively constructed.

[0025] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0031] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0032] Example 1

[0033] refer to Figures 1-4As shown, a prefabricated integrated utility tunnel component includes a first component 1, a second component 2, a first joint 3, a second joint 4, an outer blocking edge 5, an inner blocking edge 6, a positioning protrusion 7, a positioning pin 8, a sealing ring 9, a grout inlet hole 10, and a grout outlet hole 11.

[0034] The utility tunnel components can consist of only the first component 1 and the second component 2, meaning that only two types of components are used to assemble a complete utility tunnel segment. These two components can be divided into upper and lower components, or left and right components. Alternatively, the utility tunnel components can include not only the first component 1 and the second component 2, but also third, fourth, and so on components, completing the assembly of the entire utility tunnel stage through all components. The vertical and horizontal positional relationships of multiple components are more flexible.

[0035] This embodiment includes only a first component 1 and a second component 2. The first component 1 is the upper component, and the second component 2 is the lower component. The first component 1 includes a first joint 3 with an integral structure on it, and the second component 2 includes a second joint 4 with an integral structure on it. By using the assembly connection between the first joint 3 and the second joint 4, the two components are connected as one, thereby forming a complete pipe gallery segment.

[0036] The first joint 3 or the second joint 4 is provided with an outer blocking edge 5 located on both sides and along the longitudinal direction. The outer blocking edge 5 forms a blocking support component on both sides at the joint connection. During the construction of the pipe gallery, it mainly facilitates the subsequent pouring of concrete between the outer blocking edges 5 to achieve the joint connection. It also has a certain load-bearing support function and has a water-blocking effect after the pipe gallery construction is completed.

[0037] The first joint 3 is provided with an inner blocking edge 6 located between the two sides and along the longitudinal direction. The inner blocking edge 6 forms a blocking support member in the middle at the joint connection. During the construction of the pipe gallery, the inner blocking edge 6 has the function of load-bearing support and provides a foundation for the placement of the positioning protrusion 7. After the construction of the pipe gallery is completed, it has a water-blocking effect.

[0038] The internal barrier 6 has several positioning protrusions 7 arranged longitudinally at intervals. The positioning protrusions 7 are used for positioning guidance during the assembly and connection of the joint. The second joint 4 is provided with several positioning pins 8 arranged longitudinally at intervals between the two sides to form a row. The four adjacent positioning pins 8 in two adjacent rows of positioning pins 8 together form a raised positioning groove.

[0039] During the construction of the utility tunnel, the positioning protrusion is inserted into the positioning slot, thus restricting the positioning protrusion horizontally within the slot and achieving precise positioning between the two components. Furthermore, the upper component, under its own weight and with manual assistance, is clamped to the lower component; that is, the positioning protrusion 7 and the positioning post 8 are frictionally engaged, achieving initial fixation between the two components.

[0040] The first component 1, the first joint 3, the inner blocking edge 6 and the positioning protrusion 7 are reinforced concrete components that are integrated into one structure. The second component 2, the second joint 4 and the positioning pin 8 are reinforced concrete components that are integrated into one structure. The outer blocking edge 5 is integrated into one structure with the first joint 3, or the outer blocking edge 5 is integrated into one structure with the second joint 4. The integrated prefabrication ensures the forming quality of the components and also ensures the connection quality at the joints.

[0041] When the outer blocking edge 5 is arranged on the first joint 3, it facilitates the forming of two edges on one component, making the frame easier to manufacture, but the waterproof performance is slightly weaker. When the outer blocking edge 5 is arranged on the second joint 4, the two edges are located on two different components, making the manufacturing process slightly more difficult. However, the entire joint, through the outer blocking edge 5, the inner blocking edge 6, the positioning protrusion 7, and the positioning pin 8, can form a labyrinthine sealing structure with a long and winding water seepage channel, improving the waterproof performance at the joint.

[0042] An internal blocking edge 6 is provided and arranged along the centerline of the first joint 3. Two rows of positioning pins 8 are provided and arranged symmetrically along the centerline. The positioning protrusions 7 on the internal blocking edge 6 are precisely engaged between the two rows of positioning pins 8, thus completing the functions of positioning guidance and connection support. Similarly, two or more internal blocking edges 6 can be provided, and three or more rows of positioning protrusions 7 can be provided, as long as both sides of each internal blocking edge 6 are engaged by positioning protrusions 7.

[0043] The outer blocking edge 5 and the inner blocking edge 6 are both rectangular parallelepiped structures. This type of edge design is easy to manufacture and provides structural stability and reliability. The positioning protrusion 7 and the positioning pin 8 are both cylindrical. The protrusion and pin fit together through the curved surface of the cylinder, ensuring a smooth transition during connection, guidance, and fixation, avoiding damage from corner impacts. Alternatively, the cylindrical structure of the positioning protrusion 7 combined with the rectangular parallelepiped structure of the inner blocking edge 6 forms a continuous dumbbell-shaped structure. Similarly, the blocking edges, protrusions, and pins can also be other shapes, as long as they fulfill their functions.

[0044] The outer blocking edge 5, the inner blocking edge 6, and the positioning protrusion 7 are arranged at the same height, and the height of the positioning pin 8 is lower than the height of the blocking edge and the protrusion. The longitudinal length of the blocking edge and the column length of the protrusion are preferably the full length of the pipe gallery segment, which has good positioning, support, and water-blocking effects. Similarly, the blocking edge and the protrusion can also be arranged at intervals on the pipe gallery segment. A sealing ring 9 is fitted on the positioning pin 8. The sealing ring 9 can increase the friction between the pin and the protrusion, while avoiding hard collisions between the pin and the protrusion.

[0045] The outer blocking edge 5 is provided with a grout inlet hole 10, and the first joint 3 is provided with a grout outlet hole 11 that connects to the inner side of the outer blocking edge 5. After the pipe gallery components are positioned, grout is injected into the joint through the grout inlet hole 10 to cast the two joints together until the grout is discharged from the grout outlet hole 11, which means that the joint is filled with grout.

[0046] The pipe gallery components have the following advantages: 1. Enhanced shear and tensile strength at the connection points.

[0047] Dumbbell-shaped structure load-bearing capacity: The dumbbell-shaped structure (especially the thin-walled part in the middle, i.e. the internal barrier) enhances the load-bearing capacity of the connection through longitudinal reinforced concrete components. It can effectively disperse and bear the tensile and shear forces at the connection, ensuring that the joint will not be excessively deformed or damaged when the pipe gallery is under stress, thereby improving the stability of the overall structure.

[0048] Enhanced joint strength: Compared with traditional connection methods, the dumbbell-shaped structure allows the joint to distribute the load force more evenly. By using this type of reinforced concrete structure at the connection point, the load-bearing capacity and resistance to damage of the joint can be significantly improved, avoiding structural instability caused by excessive local stress.

[0049] 2. Optimize connection methods and simplify construction processes.

[0050] No complex docking processes are required: Traditional pipe rack segments typically rely on complex welding, bolting, or splicing processes, which often require extensive manual labor and precise alignment. The dumbbell-shaped structure facilitates precise positioning, avoiding misalignment or misfitting of joints that can occur with traditional connection methods. It utilizes prefabricated thickened edges on both sides and a dumbbell-shaped central edge, employing a modular slot connection method. Simply insert the prefabricated components along the slots and clamp them together for rapid structural fixation. This significantly simplifies the installation process and reduces the demands on worker skills and installation precision.

[0051] Reduced construction difficulty: The dumbbell-shaped modular slot connection method simplifies the component docking process, eliminating the need for complex machinery or extensive manual labor. During actual construction, workers only need to connect the prefabricated components through the slots for initial fixation, then lock them in place using friction, and finally grout for curing. The entire process requires minimal on-site adjustments and operations.

[0052] 3. Improve the sealing and waterproofing performance of joints.

[0053] Enhancing Joint Sealing: The dumbbell-shaped structure and the slotted joint design significantly increase the contact area at the joints, improving their sealing performance. Sealing is crucial in utility tunnel construction, especially in terms of waterproofing. Increasing the contact area at the joints better prevents moisture leakage. The modular slotted connection ensures a tight fit at the joints, reducing gaps and providing better conditions for subsequent grouting. The subsequent injection of high-strength cement grout to fill the joints further enhances waterproofing.

[0054] Pre-drilled grouting holes: The modular slot design includes pre-drilled grouting holes at key connection points, making grouting during construction more convenient and ensuring a more reliable seal. High-strength cement grout can completely fill the tiny gaps within the slot, further enhancing the waterproofing of the connection.

[0055] 4. Improve structural stability.

[0056] Stability of the slot structure: The alternating protrusions and recesses of the block slots form a reliable physical locking mechanism. The components lock together through the slots, forming a stable connection and reducing structural displacement or loosening that may occur due to installation errors or external forces.

[0057] Frictional self-locking: When the building blocks are assembled, the friction and self-locking effect between the two parts make the connection between the components more stable. This friction acts on all contact surfaces of the structure, forming a preliminary stable structure, further ensuring that the entire pipe gallery will not loosen or misalign during installation.

[0058] Increased seismic resistance of the connection: The slotted connection can effectively prevent relative slippage between pipe gallery segments and reduce the risk of earthquakes or external impacts.

[0059] 5. Optimize the prefabrication and transportation methods of components.

[0060] Reducing the weight of individual components: By adopting a dumbbell-shaped structure, the weight of each component can be effectively reduced. This is because the structure makes the middle part of the component thinner while the sides are thicker, ensuring strength while reducing the amount of concrete used and thus reducing the weight of individual components. This is especially important for the transportation and installation of precast components, significantly reducing the requirements for hoisting equipment and lowering construction costs.

[0061] Facilitates segmented transportation and hoisting: The dumbbell-shaped structure reduces the weight and volume of components, making segmented transportation more convenient and reducing the likelihood of overloading or imbalance during hoisting. Furthermore, the lighter components reduce the requirements for transportation routes, offering greater transportation flexibility, especially when constructing in urban areas or narrow spaces.

[0062] 6. Enhance overall integrity and maintainability.

[0063] Segmented management facilitates maintenance and replacement: Because the utility tunnel can be divided into multiple smaller sections, maintenance and inspection become more flexible. If a problem occurs in one section of the tunnel, the clamped section can be disassembled without affecting other parts, making individual replacement and maintenance easier. This segmented structure effectively extends the service life of the utility tunnel and simplifies subsequent maintenance work.

[0064] Strong integrity: After construction, the modular slot system can be solidified by grouting to form a stable and integrated structure, so that the connection between each segment can achieve an integrated effect, which improves the load-bearing capacity and seismic performance of the pipe gallery.

[0065] 7. Highly adaptable, flexible in combination, and scalable.

[0066] Adaptable to various application scenarios: The flexibility of the modular slot structure allows the utility tunnel to be flexibly combined according to specific needs, making it suitable for engineering projects of different sizes and types. The width, length, and number of compartments of the utility tunnel can all be adjusted according to requirements to meet the design requirements of integrated utility tunnels of different scales and functions. Whether it is a single-compartment or multi-compartment utility tunnel, the same modular slot connection method can be used, which has good adaptability and scalability. The tunnel segments can be further subdivided or merged according to actual needs to adapt to different design requirements and usage environments. Its flexibility makes this design widely applicable to various scenarios such as urban underground pipe networks, industrial pipelines, and power supply systems.

[0067] Example 2

[0068] refer to Figures 1-4 As shown, a prefabricated integrated utility tunnel structure includes the prefabricated integrated utility tunnel component of Embodiment 1. The outer blocking edge 5 is attached to the end face of the first joint 3 or the second joint 4, the inner blocking edge 6 and the positioning protrusion 7 are attached to the end face of the second joint 4, the positioning protrusion 7 is inserted into the protrusion positioning slot, and the space between the outer blocking edge 5 and the inner blocking edge 6 is filled with grout 12.

[0069] The first component 1 and the second component 2 form a single-compartment, double-compartment, or multi-compartment utility tunnel. A single-section utility tunnel is divided into upper and lower parts. Taking a double-compartment tunnel as an example, the lower part of the tunnel includes a base plate, a lower left side wall, a lower right side wall, and a lower middle partition wall; the upper part includes a top plate, an upper left side wall, an upper right side wall, and an upper middle partition wall. The side walls and partition walls of both parts have a first joint 3 or a second joint 4, which connects the utility tunnels.
