Description

Technical Field

[0001] The present application belongs to the technical field of prefabricated buildings, and specifically relates to an installation method of an assembled prefabricated integrated pipe gallery structure. Background Art

[0002] The comprehensive pipeline corridor is an important form of urban underground pipeline facilities. By concentrating multiple pipelines in one pipeline corridor, it can effectively reduce repeated road excavation, improve the utilization rate of above-ground and underground space, reduce the utilization cost of urban underground space, and facilitate pipeline maintenance and management.

[0003] However, the existing prefabricated integrated pipe gallery structures generally use cast-in-place reinforced concrete or integral prefabricated reinforced concrete structures, and most of the prefabricated sections of the pipe gallery are heavy, especially the 2-meter-long, double-bin prefabricated sections, which weigh nearly 40 tons. Such heavy prefabricated sections have high requirements for on-site roads and lifting equipment during transportation and hoisting, and are difficult to construct. In addition, the large size of a single prefabricated section increases the difficulty of transportation and installation.

[0004] In addition, the heavy weight of the segments and the restrictions on the construction site usually lead to the prefabricated segments being too short, increasing the number of longitudinal joints, which may increase the risk of water seepage. At the same time, the waterproof performance of the joints is always a difficult point. The sealing of the segment connection is poor, which is prone to water seepage problems, resulting in structural damage after long-term use of the corridor.

[0005] Therefore, how to reduce the weight of a single prefabricated segment, simplify the installation process, and effectively solve the hidden danger of joint water seepage has always been a difficult problem in the design and construction of integrated pipe corridors. To solve this problem, the present application proposes an installation method for an assembled prefabricated integrated pipe corridor structure. Summary of the invention

[0017] Furthermore, in step 4, dry hard mortar is used to seal the joints before grouting, and a grouting machine is used to inject high-strength cement slurry. The grouting holes are selected from the center of each segment to both ends until the grouting holes overflow with slurry. After the grouting is completed, the grouting holes and the grouting holes are closed.

[0018] Furthermore, the first component is an upper component, and the second component is a lower component. In step 2, the second component is hoisted into place, and in step 3, the first component is hoisted into place.

[0039] The following non-limiting examples are provided to illustrate the present application.

[0040] Example 1

[0041] refer to Figure 1 to Figure 4 As shown, a method for installing an assembled prefabricated integrated pipe gallery structure includes the following steps: Step 1, construction preparation work, the construction preparation work includes foundation pit excavation work, pipe gallery cushion layer work and bottom plate outsourcing waterproofing work.

[0042] Step 2, hoist the lower components of the first component 1 and the second component 2 into place; step 3, hoist the upper components of the first component 1 and the second component 2 into place. The first component 1 is the upper component, and the second component 2 is the lower component. In step 2, the second component 2 is hoisted into place, and in step 3, the first component 1 is hoisted into place.

[0043] The first component 1 includes a first joint 3, and the second component 2 includes a second joint 4. 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, and the first joint 3 is provided with an inner blocking edge 6 located between the two sides and along the longitudinal direction. The outer blocking edge 5 is attached to the first joint 3 or the second joint 4, and the inner blocking edge 6 is attached to the second joint 4.

[0044] A plurality of positioning protrusions 7 are arranged at longitudinal intervals along the internal blocking edge 6, and a plurality of positioning posts 8 are arranged at longitudinal intervals between the two sides to form a column shape on the second joint 4. Four adjacent positioning posts 8 in two adjacent columns of positioning posts 8 together form a raised positioning groove. The positioning protrusion 7 is inserted into the raised positioning groove, and a preliminary fixation is formed between the positioning protrusion 7 and the positioning post 8 through friction.

[0045] The thickness of the outer blocking edge, the size of the inner blocking edge and the positioning protrusion, as well as the diameter, height, and spacing of the positioning clamping column need to be comprehensively considered according to the size of the pipe gallery structure and the thickness of the side wall through calculation and testing to ensure the strength of the joint. A crane or gantry crane is used for lifting and installation operations. Precise alignment is required during installation. The upper component is clamped with the lower component under its own weight and manual assistance, and the friction between the two components forms a preliminary stable structure.

[0046] Step 4: Connect the first component 1 and the second component 2 by casting, and cast and fill the grouting body 12 between the outer blocking edge 5 and the inner blocking edge 6 .

[0047] Before grouting, dry hard mortar is used to seal the joints to prevent the grouting slurry from overflowing. A grouting machine is used to inject high-strength cement slurry (the slurry mix ratio is determined by tests or design verification). The slurry inlet holes are selected from the center of each segment to both ends until the slurry outlet holes overflow with slurry. After grouting, the slurry inlet and outlet holes are closed with rubber plugs. After grouting, the grouting corridor segments shall not be disturbed or loaded before the slurry strength reaches the design requirements to ensure the integrity and airtight waterproof function of the prefabricated integrated corridor.

[0048] Repeat steps 2 and 3 to realize the step-by-step assembly of the corridor segments. The longitudinal corridor segments are connected by sockets. When the corridor segments to be grouted do not interfere with the corridor segments to be assembled, step 4 is used to perform grouting on the corridor segments to be grouted.

[0049] The pipe gallery components may only include the first component 1 and the second component 2, that is, only two components are used to complete the assembly and assembly of the complete pipe gallery segment, and the two components are divided into an upper component and a lower component, or divided into a left component and a right component. The pipe gallery components may also include not only the first component 1 and the second component 2, but also a third, fourth, and so on component, and the assembly and assembly of the complete pipe gallery stage is completed by all the components, and the upper and lower, left and right positional relationships of multiple components are more flexible.

[0050] This embodiment only includes a first component 1 and a second component 2, wherein the first component 1 is an upper component and the second component 2 is a lower component. The first component 1 includes a first joint 3 of an integral structure thereon, and the second component 2 includes a second joint 4 of an integral structure thereon. The first joint 3 and the second joint 4 are assembled to connect the two components into one, thereby forming a complete pipe gallery segment.

[0051] The first joint 3 or the second joint 4 is provided with outer blocking edges 5 located on both sides and along the longitudinal direction. The outer blocking edges 5 form blocking support components on both sides at the joint connection. During the construction of the tunnel, it is mainly convenient for 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-retaining effect after the construction of the tunnel is completed.

[0052] The first joint 3 is provided with an internal blocking edge 6 located between the two sides and along the longitudinal direction. The internal blocking edge 6 forms a blocking support member located in the middle at the joint connection. During the construction of the tunnel, the internal blocking edge 6 has a load-bearing support function and provides a basis for the placement of the positioning protrusion 7. It has a water-retaining effect after the construction of the tunnel is completed.

[0053] A plurality of positioning protrusions 7 are arranged longitudinally at intervals on the inner blocking edge 6, and the positioning protrusions 7 are used for positioning guidance when the joints are assembled and connected. The second joint 4 is provided with a plurality of positioning clamping columns 8 arranged longitudinally at intervals between the two sides to form a column shape, and four adjacent positioning clamping columns 8 in two adjacent columns of positioning clamping columns 8 together surround a raised positioning clamping groove.

[0054] During the construction of the pipe gallery, the positioning protrusion is inserted into the protrusion positioning slot, and the positioning protrusion is horizontally restricted in the protrusion positioning slot, so that the two components can be accurately positioned. The upper component is clamped with the lower component under the action of its own weight and manual assistance, that is, the positioning protrusion 7 and the positioning clamp column 8 are frictionally fitted to achieve the initial fixation between the two components.

[0055] The first component 1, the first joint 3, the internal blocking edge 6 and the positioning protrusion 7 are reinforced concrete with an integrated structure, the second component 2, the second joint 4 and the positioning column 8 are reinforced concrete with an integrated structure, the outer blocking edge 5 and the first joint 3 are an integrated structure, or the outer blocking edge 5 and the second joint 4 are an integrated structure. The integrated prefabrication ensures the molding quality of the components and also ensures the connection quality at the joints.

[0056] When the outer blocking edge 5 is arranged on the first joint 3, it is convenient to form two blocking edges on one component, which is convenient for the processing and manufacturing of the frame, but the waterproof performance is slightly weaker. When the outer blocking edge 5 is arranged on the second joint 4, the two blocking edges are respectively located on two components, which is slightly more difficult to process and manufacture, but the entire joint can form a labyrinth sealing structure with a long and tortuous water seepage channel through the outer blocking edge 5, the inner blocking edge 6, the positioning protrusion 7 and the positioning clamping column 8, thereby improving the waterproof performance of the joint.

[0057] The internal blocking edge 6 is provided with one row and arranged along the center line of the first joint 3, and the positioning posts 8 are provided with two rows and arranged symmetrically along the center line, so that the positioning protrusion 7 on one row of the internal blocking edge 6 is just clamped between the two rows of positioning posts 8, completing the functions of positioning guide and connection support. Similarly, the internal blocking edge 6 can also be provided with two or more rows, and the positioning protrusion 7 can also be provided with three or more rows, as long as both sides of each row of the internal blocking edge 6 are clamped by the positioning protrusion 7.

[0058] The outer blocking edge 5 is a rectangular parallelepiped structure, and the inner blocking edge 6 is a rectangular parallelepiped structure. The blocking edge of this structure is easy to manufacture, and the structure is stable and reliable. The positioning protrusion 7 is a cylindrical structure, and the positioning clamping column 8 is a cylindrical structure. The protrusion and the clamping column fit each other through the arc surface of the cylinder, and the transition during the connection guide and the fitting and fixing is smooth, avoiding the problem of end corner collision damage. In other words, the cylindrical structure of the positioning protrusion 7 is combined with the rectangular parallelepiped structure of the inner blocking edge 6 to form a continuous dumbbell-shaped structure. Similarly, the blocking edge, protrusion and clamping column can also be structures of other shapes as long as they can achieve their own functions.

[0059] 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 column 8 is lower than the height of the blocking edge and the protrusion. The longitudinal length of the blocking edge and the length of the protrusion are preferably the full length of the corridor segment, which has good positioning, support and water blocking effects. Similarly, the blocking edge and the protrusion can also be arranged at segment intervals on the corridor segment.

[0060] The positioning post 8 is sleeved with a sealing ring 9, which can increase the friction between the post and the protrusion and avoid hard collision between the post and the protrusion. When the clamping part of the positioning protrusion 7 and the positioning post 8 is prefabricated, a margin is reserved, and the sealing ring 9 is used to fill the margin so that the positioning protrusion 7 and the positioning post 8 are clamped to each other.

[0061] The outer barrier edge 5 is provided with a grout inlet hole 10, and the first joint 3 is provided with a grout outlet hole 11 connected to the inner side of the outer barrier edge 5. After the positioning of the pipe gallery components is completed, grout is injected into the joint through the grout inlet hole 10 to cast and connect the two joints into one, until the grout is discharged from the grout outlet hole 11, indicating that the joint is filled with grout.

[0062] A single-storage, double-storage or multi-storage pipe gallery is formed between the first component 1 and the second component 2. A single-segment pipe gallery is divided into two parts, upper and lower. Taking a double-storage pipe gallery as an example, the pipe gallery components of the lower part include a bottom plate, a lower left side wall, a lower right side wall and a middle-lower partition wall, and the pipe gallery components of the upper part include a top plate, an upper left side wall, an upper right side wall and a middle-upper partition wall. The side walls and partition walls of the upper and lower parts have a first joint 3 or a second joint 4, and the pipe gallery is connected through the two joints.

[0063] The pipe gallery components have the following advantages: 1. Enhanced shear and tensile resistance of the connection parts.

[0064] The bearing capacity of the dumbbell-shaped structure: The dumbbell-shaped structure (especially the thin-walled part in the middle, i.e. the internal blocking edge) enhances the bearing capacity of the connection parts through longitudinal reinforced concrete components. It can effectively disperse and withstand the tension and shear force at the connection, ensuring that when the corridor is subjected to stress, the joints will not be excessively deformed or damaged, thereby improving the stability of the overall structure.

[0065] Enhance the strength of the connection joint: Compared with the traditional connection method, the dumbbell-shaped structure enables the joint to distribute the load more evenly. By using this shape of reinforced concrete structure at the connection part, the bearing capacity and anti-destruction ability of the joint can be significantly improved, avoiding structural instability caused by excessive local stress.

[0066] 2. Optimize the connection method and simplify the construction process.

[0067] No need for complex docking process: Traditional pipe gallery segments usually rely on complex welding, bolting or splicing processes, which often require a lot of manual operation and precise alignment work. The dumbbell-shaped structure helps with precise positioning, avoiding the dislocation or misalignment of the joints that may occur in traditional connection methods. It is prefabricated through thickened edges on both sides and dumbbell-shaped edges in the middle, and adopts a building block slot structure connection method. The prefabricated components only need to be inserted along the slot and clamped together to achieve rapid fixation of the structure. This greatly simplifies the installation process and reduces the requirements for workers' operating skills and installation accuracy.

[0068] Reduce construction difficulty: The dumbbell-shaped building block slot connection method simplifies the docking work of components, and does not require complex machinery or a large amount of manual docking. In the actual construction process, construction workers only need to dock the prefabricated parts through the slots for preliminary fixation, then lock them through friction, and finally grouting and curing. The whole process does not require too much on-site adjustment and operation.

[0069] 3. Improve seam sealing and waterproof performance.

[0070] Strengthen the joint sealing effect: The geometric shape of the dumbbell-shaped structure itself and the design of the slot joint greatly increase the contact area at the joint, which enhances the sealing of the joint. In the construction of the pipeline corridor, sealing is crucial, especially in terms of waterproof performance. By increasing the contact area of ​​the joint, water leakage can be better prevented. The building block slot connection method makes the joint part bite tightly, reduces the gap between the joints, and provides better conditions for subsequent grouting. By injecting high-strength cement slurry to fill the joint later, the waterproof performance is further enhanced.

[0071] Pre-reserved grouting holes: Grouting holes are reserved at key connection locations during the design of the building block slots, making grouting more convenient and more reliable during construction. High-strength cement slurry can completely fill the tiny gaps in the slots, further enhancing the waterproofness of the connections.

[0072] 4. Improve structural stability.

[0073] Stability of the slot structure: The convex and concave parts of the building block slot are arranged alternately to form a reliable physical locking mechanism. Each component is locked through the slot to form a stable connection with each other, reducing the structural displacement or looseness that may occur due to installation errors or external forces.

[0074] Friction self-locking: When the building block slots are spliced, the friction and self-locking effect between the two parts make the connection between the components more stable. This friction acts on each contact surface of the structure, forming a preliminary stable structure, further ensuring that the entire pipe gallery will not loosen or misalign during the installation process.

[0075] Increase the seismic resistance of the connection: The slot connection can effectively prevent relative slippage between the corridor segments and reduce the risks caused by earthquakes or external shocks.

[0076] 5. Optimize the prefabrication and transportation methods of components.

[0077] Reduce the weight of a single component: With the dumbbell-shaped structure, the weight of each component can be effectively reduced, because this structure makes the middle part of the component thinner and the two sides thicker, which not only ensures strength, but also reduces the amount of concrete used and reduces the weight of a single component. This is particularly important for the transportation and installation of prefabricated components, which can significantly reduce the requirements for lifting equipment and reduce construction costs.

[0078] Convenient for segmented transportation and hoisting: When a dumbbell-shaped structure is used, the weight and volume of the components are reduced, making segmented transportation more convenient and less prone to overload or imbalance problems during the hoisting process. In addition, lighter components can also reduce the requirements for transportation roads, especially when constructing within cities or in narrow areas, and have better transportation flexibility.

[0079] 6. Enhance integrity and maintainability.

[0080] Segment management for easy maintenance and replacement: Since the pipe gallery segments can be divided into multiple small pieces, maintenance and inspection work becomes more flexible. If a part of the pipe gallery has a problem, the slot part can be disassembled without affecting other parts, making it easy to replace and maintain separately. This segmented structure can effectively extend the service life of the pipe gallery and simplify subsequent maintenance work.

[0081] Strong integrity: After the construction of the building block slot system is completed, it can form a stable and integrated structure through grouting and curing, so that the connection between each segment can achieve an integrated effect, thereby improving the bearing capacity and seismic resistance of the pipeline corridor.

[0082] 7. Strong adaptability, flexible combination and scalability.

[0083] Adaptable to a variety of usage scenarios: The flexibility of the building block slot structure allows the corridor to be flexibly combined according to specific needs, suitable for engineering projects of different sizes and types. The width, length, number of compartments, etc. of the corridor can be adjusted according to needs to meet the design requirements of comprehensive corridors of different scales and functions. Whether it is a single-bay or multi-bay corridor, the same building block slot connection method can be used, which has good adaptability and scalability. The corridor segments can be further subdivided or merged according to actual needs to adapt to different design requirements and usage environments. Its flexibility makes the design widely used in various scenarios such as urban underground pipelines, industrial zone pipelines, power supply systems, etc.

[0084] An assembled prefabricated integrated pipe gallery structure includes the assembled prefabricated integrated pipe gallery component of Example 1, the outer blocking edge 5 fits the end face of the first joint 3 or the second joint 4, the inner blocking edge 6 and the positioning protrusion 7 fit the end face of the second joint 4, the positioning protrusion 7 is inserted into the protrusion positioning groove, and the space between the outer blocking edge 5 and the inner blocking edge 6 is poured and filled with grouting body 12.
