Description

Technical Field

[0001] The invention relates to the technical field of construction, is applicable to a coal powder conveying pipeline in a cement production line, and particularly relates to a crossing pipeline component and a construction method thereof. Background Art

[0002] In the related technologies, in industrial buildings, civil buildings and municipal engineering, traditional sealing technologies and fixing methods when medium pipelines pass through interlayers or floor slabs have some significant limitations and problems in terms of sealing, structural stability, stress state and construction process.

[0003] Taking sealing as an example, Figure 1 As shown in the traditional through-floor structure in the related art shown, the displacement caused by the superimposed weight of the medium pipes will form a second leakage channel XL2. In the process of installing the sealing material, an open filling sealing process is usually adopted, that is, the gap between the pipe and the interlayer is directly filled with sealing materials, such as filling flexible fillers and waterproof ointment at the same time to achieve a sealing effect. However, the above-mentioned open filling method is difficult to ensure the uniformity and density of the sealing material filling, and it is easy to have problems such as bubbles and gaps. In addition, the waterproof ointment mixed with rigid sealing materials in the filler will further reduce the flexible sealing effect. In the process of installing the sealing material, there is no upper and lower constraint device structure in the sealing space, and the construction operator cannot fully fill the flexible material densely, so that the sealing material is in a three-stress state, and XL2 gaps and honeycomb pores are often generated, causing leakage risks. At the same time, for the uneven settlement deformation of buildings and structures and the working vibration and distortion of the medium pipeline and other on-site environments, the bonding performance of the waterproof paste between the medium pipeline and the embedded casing is limited, and it does not have flexible performance, and the sealing effect is limited.

[0004] Taking structural stability and stress state as an example, traditional pipe fixing brackets are usually used in related technologies to achieve positioning constraints in the horizontal direction. However, traditional brackets can only perform positioning constraints in the horizontal direction and cannot effectively cope with the weight and external forces of the vertical pipeline, causing the entire pipeline to be in a "compressed" state and prone to bending and deformation. In addition, because the traditional bracket design does not take into account factors such as vibration, pressure swing, and water hammer that may occur when the medium pipeline is working, long-term use may cause sealing failure. At the same time, for longer or heavier pipelines, an additional bottom support structure is required, which increases the complexity and cost of construction.

[0005] Taking the construction process as an example, the process level of open filling type depends on the operating skills and experience of the construction personnel, and the construction quality and efficiency fluctuate greatly. Once the seal fails, the repair process is complicated and time-consuming, and it is often necessary to dismantle part of the structure and re-construct. Therefore, the quality of the above construction process is affected by various factors of "man-machine-material-method-environment", and the construction is difficult and costly. Summary of the invention

[0006] In view of this, the present invention provides a crossing pipe assembly and a construction method thereof to solve the problems of poor sealing, unstable positioning, unreasonable pipe stress, etc. existing in the prior art.

[0007] In a first aspect, the present invention provides a pipeline crossing assembly, comprising:

[0008] A medium pipeline passes through the partition and a sealed space is provided between the medium pipeline and the partition, wherein the sealed space is filled with a sealing material;

[0009] A first half pipe clamp structure is arranged outside the medium pipeline and fixed on the first side surface of the barrier layer, wherein the first half pipe clamp structure comprises two first half covers that cooperate with each other;

[0010] A second half pipe clamp structure is arranged outside the medium pipeline and fixed on the second side surface of the barrier layer, and the second half pipe clamp structure includes two second half covers that cooperate with each other;

[0011] At least one of the first Haff pipe clamp structure and the second Haff pipe clamp structure is provided with an injection hole, and at least one of the first Haff pipe clamp structure and the second Haff pipe clamp structure is also provided with an exhaust hole, and the injection hole and the exhaust hole are both connected to the sealed space and the outside.

[0012] Beneficial effects: The present invention provides a crossing pipe assembly, which transforms the construction method of the "open filling" sealing process in the traditional construction field into an "assembled" sealing installation method, and combines the pipe support with the sealing structure to achieve an integrated function, and transforms the original pipe's stress mode from the original "compression" state to the "tension" state, thereby changing its stress state and overcoming the deficiencies in the original standard.

[0013] In an optional embodiment, a first Hough chassis is provided at one end of the first Hough pipe clamp structure facing the partition, and the first Hough chassis is arranged around the first Hough pipe clamp structure and fixed on the first side surface of the partition;

[0014] A second Hough chassis is provided at one end of the second Hough pipe clamp structure facing the partition, and the second Hough chassis is arranged around the second Hough pipe clamp structure and fixed on the second side surface of the partition;

[0015] Wherein, the first Hough chassis and the second Hough chassis jointly seal the sealed space.

[0016] Beneficial effects: On the one hand, the first half chassis and the second half chassis jointly block the sealing space to prevent the leakage of the sealing material, significantly improve the sealing effect, and ensure the waterproof performance; on the other hand, the wing ring plate also shares part of the weight of the pipeline, changes the original force mode, puts the pipeline in a more reasonable force state, and reduces the possibility of flexural deformation. At the same time, by fixing the wing ring plate on both sides of the partition, more precise horizontal and vertical positioning is achieved, ensuring the verticality and flatness of the pipeline installation, and improving the long-term operation stability of the system.

[0017] In an optional embodiment, a first elastic sealing ring is sandwiched between the first half chassis and the partition, and / or a second elastic sealing ring is sandwiched between the second half chassis and the partition.

[0018] Beneficial effects: The above design not only enhances the sealing performance, but also increases the influence of the relative displacement between the medium pipeline (including the half structure) and the floor slab on the sealing effect, thereby realizing the "flexible" function of the overall seal, and can effectively prevent moisture and external impurities from entering the sealed space, thereby improving the overall waterproof performance.

[0019] In an optional embodiment, at least one side surface of the first elastic sealing ring is provided with a serrated contact surface; and / or at least one side surface of the second elastic sealing ring is provided with a serrated contact surface.

[0020] Beneficial effects: On the one hand, the serrated contact surface significantly increases the friction between the elastic sealing ring and the interlayer or wing ring plate, making the sealing ring less likely to slide and enhancing the stability of the overall structure. On the other hand, the serrated structure can better fit the slight unevenness of the interlayer surface, ensuring that the sealing ring can form an effective sealing barrier on the irregular surface. In addition, the flexible serrated contact surface can absorb the slight displacement between the interlayer and the Haff pipe clamp structure to a certain extent, reducing the risk of sealing failure caused by building settlement or vibration.

[0021] In an optional embodiment, a first elastic sealing sleeve is sandwiched between the first half pipe clamp structure and the medium pipeline, and / or a second elastic sealing sleeve is sandwiched between the second half pipe clamp structure and the medium pipeline.

[0022] Beneficial effects: On the one hand, the elastic sealing bushing can effectively absorb the vibration and stress changes generated when the medium pipeline is working, reducing the risk of sealing failure caused by vibration and ensuring the long-term stable operation of the system. On the other hand, the elastic sealing bushing can evenly disperse the pressure between the Haff pipe clamp structure and the medium pipeline, avoiding local stress concentration, extending the service life of the sealing structure, and reducing maintenance requirements. In addition, through the buffering effect of the flexible elastic sealing bushing, the entire crossing pipeline assembly shows higher stability and durability when facing external environmental changes (such as temperature changes, vibrations, etc.), ensuring the long-term reliable operation of the system.

[0023] In an optional embodiment, a plurality of first sawtooth rings are formed on the inner peripheral wall of the first elastic sealing bushing, and the plurality of first sawtooth rings are arranged around the outer peripheral wall of the medium pipeline and are spaced apart along the axial direction thereof;

[0024] And / or, a plurality of second sawtooth rings are formed on the inner peripheral wall of the second elastic sealing bushing, and the plurality of second sawtooth rings are arranged around the outer peripheral wall of the medium pipeline and are spaced apart along the axial direction thereof.

[0025] Beneficial effects: Multiple first serrated rings and second serrated rings are respectively arranged around the outer peripheral wall of the medium pipeline, forming a multiple sealing barrier, which significantly enhances the sealing effect and prevents medium leakage. At the same time, multiple serrated rings are arranged at intervals along the axial direction, which can evenly disperse the pressure between the Haff pipe clamp structure and the medium pipeline, avoid local stress concentration, extend the service life of the sealing structure, and reduce maintenance requirements.

[0026] In an optional embodiment, the partition is a floor, the first half pipe clamp structure is fixed to the upper surface of the floor, and the exhaust hole extending in the up-down direction is formed in the first half pipe clamp structure;

[0027] The second Hough pipe clamp structure is fixed on the lower surface of the floor slab, and the injection hole extending in the up-down direction is formed in the second Hough structure.

[0028] Beneficial effects: The present invention achieves efficient filling of the sealing material by setting the exhaust hole in the first half pipe clamp structure on the upper surface of the floor slab and setting the injection hole in the second half pipe clamp structure on the lower surface of the floor slab. This design ensures that the sealing material is filled from bottom to top until the sealing material appears in the exhaust hole, ensuring that the sealed space is completely filled without bubbles and gaps.

[0029] In an optional embodiment, the pipeline crossing component further includes:

[0030] A wall sleeve, which is inserted into the interlayer and is provided with a plurality of wing ring fixing plates, wherein the plurality of wing ring fixing plates are arranged at intervals along the axial direction of the wall sleeve and are all arranged around the outer peripheral wall thereof, and the wing ring fixing plates are fixedly connected to the structural steel bars of the interlayer;

[0031] The medium pipeline is inserted into the wall-penetrating sleeve, and the sealing space is defined between the outer peripheral wall of the medium pipeline and the inner peripheral wall of the wall-penetrating sleeve.

[0032] Beneficial effects: On the one hand, the wing ring fixing plates are arranged at intervals along the axial direction of the wall sleeve, which can evenly disperse the pressure from the interlayer, avoid local stress concentration, and extend the service life of the wall sleeve. On the other hand, the wing ring fixing plates are fixedly connected to the interlayer structural steel bars, which significantly enhances the stability of the wall sleeve, ensures its accurate position in the interlayer, and reduces installation errors.

[0033] At the same time, the wing ring fixing plate provides an additional support point for the wall sleeve, especially during the interlayer pouring process, to ensure that the wall sleeve will not be displaced or deformed.

[0034] In an optional embodiment, the wing ring fixing plate includes a first wing ring plate, an intermediate wing ring plate and a second wing ring plate; wherein, the first wing ring plate is fixed to the first side surface of the partition layer by chemical anchors, the second wing ring plate is fixed to the second side surface of the partition layer by chemical anchors, and the intermediate wing ring plate is located between the first wing ring plate and the second wing ring plate.

[0035] In a second aspect, the present invention further provides a construction method of a pipe-crossing assembly, which is applied to the pipe-crossing assembly as described in the embodiment of the first aspect of the present invention, comprising:

[0036] Pre-embed a wall sleeve with a wing ring fixing plate at a predetermined position of the interlayer, and fix the wing ring fixing plate to the structural steel bars of the interlayer;

[0037] Insert the medium pipeline into the pre-buried wall bushing and make a preliminary positioning of the medium pipeline;

[0038] Installing a first Hough pipe clamp structure on the medium pipeline, and fixing the first Hough pipe clamp structure on the surface of the first side of the partition;

[0039] On the premise that the medium pipeline is fixed between two adjacent partitions, a vibration-damping corrugated compensator is arranged and installed on the medium pipeline;

[0040] Installing a second Hough pipe clamp structure on the medium pipeline, and fixing the second Hough pipe clamp structure on the surface of the second side of the partition;

[0041] The sealing material is poured into the injection hole into the sealed space until the sealing material overflows from the exhaust hole.

[0042] In an optional embodiment, the step of installing a first Hough pipe clamp structure on the medium pipeline and fixing the first Hough pipe clamp structure on the surface of the first side of the partition layer specifically includes:

[0043] The two first half covers are locked on the outer peripheral wall of the medium pipeline by means of first fastening bolts, and the first half chassis and the first wing ring plate are fixed to the first side surface of the barrier layer by means of chemical anchor bolts in sequence, wherein the bottom of the nut of the first fastening bolt adopts an anti-reverse serrated structure;

[0044] The step of installing a second Hough pipe clamp structure on the medium pipeline and fixing the second Hough pipe clamp structure on the surface of the second side of the partition specifically includes:

[0045] The two second half covers are locked on the outer peripheral wall of the medium pipeline by the second fastening bolts, and the second half chassis and the second wing ring plate are fixed to the second side surface of the partition in turn by chemical anchor bolts, wherein the bottom of the nut of the second fastening bolt adopts an anti-reverse serrated structure.

[0046] The beneficial effects of the construction method of the pipe-crossing assembly of the second embodiment of the present invention are similar to the beneficial effects of the pipe-crossing assembly of the first embodiment of the present invention, and will not be repeated here.

[0065] The following describes a pipe-crossing assembly and its construction method provided by the present invention with reference to the accompanying drawings. It should be noted that the pipe-crossing assembly of the present invention is applicable to situations where the pipe needs to pass through the wall, floor or other structural barriers of a building or structure, such as passing through the wall of a building, passing through the floor or basement ceiling, passing through the wall or floor of an underground facility or civil air defense project, and the present invention does not impose any special restrictions here. For example, if the sealing effect is required to be high, the present invention is applicable to walls, floors and civil air defense external protective structures; or, if the overall medium pipeline stress is required to be improved, the present invention is applicable to passing through the floor structure.

[0066] like Figures 3 to 9 As shown, the crossing pipe assembly according to the first embodiment of the present invention includes a medium pipe 2, a first Hough pipe clamp structure 3 and a second Hough pipe clamp structure 4.

[0067] The medium pipeline 2 passes through the barrier layer 1 and a sealing space is provided between the medium pipeline 2 and the barrier layer 1 , and the sealing space is filled with a sealing material 5 .

[0068] The first Haff pipe clamp structure 3 is sleeved on the outside of the medium pipeline 2 and fixed on the first side surface 11 of the partition 1. The first Haff pipe clamp structure 3 includes two first Haff covers 31 that cooperate with each other; the second Haff pipe clamp structure 4 is sleeved on the outside of the medium pipeline 2 and fixed on the second side surface 12 of the partition 1. The second Haff pipe clamp structure 4 includes two second Haff covers 41 that cooperate with each other.

[0069] Among them, at least one of the first Haff pipe clamp structure 3 and the second Haff pipe clamp structure 4 is provided with an injection hole 42, and at least one of the first Haff pipe clamp structure 3 and the second Haff pipe clamp structure 4 is also provided with an exhaust hole 32, and the injection hole 42 and the exhaust hole 32 are both connected to the sealed space and the outside.

[0070] The internal parts of the through-pipe assembly according to the embodiment of the present invention are described in detail as follows:

[0071] The medium pipeline 2 serves as a channel for conveying fluid (such as water, gas and fixed powder, etc.), passes through the partition 1 and a sealed space is provided between the partition 1. The sealed space is used to fill the sealing material 5 to ensure the waterproof sealing between the pipeline and the partition 1. Among them, the sealing material 5 is usually a material such as silicone sealant, foamed polyethylene or polyurethane. The function of the sealing material 5 is to prevent leakage of the medium and penetration of external moisture, while providing a certain vibration reduction effect. It should be pointed out that the partition 1 includes a wall, a floor or other external defense protection structure, and the present invention does not make any special restrictions here.

[0072] The first half pipe clamp structure 3 is composed of two first half covers 31 that cooperate with each other, and is locked on one end of the first side of the adjacent barrier 1 of the medium pipeline 2 (for example, the upper end of the medium pipeline 2) by fastening bolts. The first half pipe clamp structure 3 can be provided with an injection hole 42 and / or an exhaust hole 32, and its main function is to provide support and positioning for the medium pipeline 2, and to assist in the injection of the sealing material 5 or the exhaust of air.

[0073] The second half pipe clamp structure 4 is similar to the first half pipe clamp structure 3, and is composed of two second half covers 41 that cooperate with each other, and is locked on one end of the second side of the adjacent barrier 1 of the medium pipeline 2 (for example, the lower end of the medium pipeline 2) by fastening bolts. The second half pipe clamp structure 4 can also be provided with an injection hole 42 and / or an exhaust hole 32, which is used to support and position the other side of the medium pipeline 2 and assist in the sealing process.

[0074] The injection hole 42 is used to inject the sealing material 5 into the sealed space, and the exhaust hole 32 is used to exhaust the excess gas in the sealed space during the injection process to maintain the air pressure balance, and the injection hole 42 and the exhaust hole 32 can be arranged in various forms, for example, one of the first half pipe clamp structure 3 and the second half pipe clamp structure 4 is provided with an injection hole 42 and the other is provided with an exhaust hole 32; for another example, the first half pipe clamp structure 3 is provided with an injection hole 42 and an exhaust hole 32, and the second half pipe clamp structure 4 is also provided with an injection hole 42 and an exhaust hole 32. The present invention is not particularly limited here, as long as the crossing pipe assembly has at least one exhaust hole 32 and at least one injection hole 42 at the same time.

[0075] Based on the above structure, the interlayer 1 is taken as an example for explanation, the first half pipe clamp structure 3 and the second half pipe clamp structure 4 are respectively fixed on the upper surface and the lower surface of the floor, and the specific working principle of the through pipe assembly of the present invention is as follows:

[0076] like Figure 5 As shown, by precisely controlling the torque of the fastening bolts on the Haff pipe clamp structure, a group of Haff pipes can exert a "grip force" on the medium pipeline 2. The grip force is based on the positive pressure formula f=μ×N in the friction force, where f is the friction force, μ is the friction coefficient, and N is the positive pressure. When the fastening bolts on the Haff pipe clamp structure are tightened, the positive pressure N generated will firmly lock the medium pipeline 2 to ensure its vertical stability (that is, the axial direction of the medium pipeline 2).

[0077] like Figure 5 As shown, at the same time, the weight W of the medium pipeline 2 is evenly applied to the bottom of the first half pipe clamp structure 3, and is dispersed to the layered floor through the fixed structure between the first half pipe and the floor. In this process, the condition f = W is satisfied, that is, the gripping force is equal to the weight of the pipeline, thereby realizing the positioning function of the medium pipeline 2 in the vertical direction. Furthermore, the fixed structure between the first half pipe and the floor (such as the chemical anchor 7) provides a fixed point, ensuring the stability of the overall structure, while meeting the positioning requirements in the horizontal direction.

[0078] It can be understood that based on the force analysis of the medium pipeline 2, the present invention reasonably configures the pipeline expansion joint, eliminates the original fixed bracket, and changes the force mode of the pipeline. The traditional pipeline bracket puts the pipeline in a "single-rod compression state" (such as Figure 2 As shown), the present invention changes the stress state of the pipeline into a segmented "tension state" (as shown in FIG. Figure 5 As shown in the figure, the deadweight and external force of the pipeline are dispersed, and the risk of sealing failure caused by the bending deformation of the overall pipeline is reduced. In this way, the total weight of the overall pipeline is decomposed and dispersed to each floor slab, eliminating the "bending" deformation of the original overall medium pipeline 2.

[0079] From the above, the specific working process of the pipeline crossing assembly according to the embodiment of the present invention is as follows:

[0080] First, a wall sleeve 6 with a wing ring fixing plate 61 is embedded in a predetermined position of the interlayer 1 and fixed to the structural steel bars of the interlayer 1 to ensure that the wall sleeve 6 remains stable during the pouring of the interlayer 1. Next, the medium pipeline 2 is passed through the embedded wall sleeve 6 and the medium pipeline 2 is preliminarily positioned to ensure that its verticality and flatness meet the requirements.

[0081] A first half pipe clamp structure 3 is installed on the medium pipeline 2, and two first half covers 31 are locked on the outer peripheral wall of the medium pipeline 2 using fastening bolts, and the first half pipe clamp structure 3 is fixed to the first side surface 11 of the barrier 1 through a fixing member (such as a chemical anchor bolt 7). A second half pipe clamp structure 4 is installed on the medium pipeline 2, and two second half covers 41 are locked on the outer peripheral wall of the medium pipeline 2 using fastening bolts, and the second half pipe clamp structure 4 is fixed to the second side surface 12 of the barrier 1 through a fixing member (such as a chemical anchor bolt 7).

[0082] On the premise that the medium pipeline 2 is fixed between two adjacent partitions 1 (used to isolate the weight transfer of the upstream pipeline), a vibration-damping corrugated compensator is arranged and installed on the medium pipeline 2 to absorb the stress changes caused by the working vibration and thermal expansion and contraction of the pipeline.

[0083] It is confirmed that at least one of the first half pipe clamp structure 3 and the second half pipe clamp structure 4 is provided with an injection hole 42, and the other is provided with an exhaust hole 32. The sealing material 5 is poured into the sealed space through the injection hole 42 of one of the half pipe clamp structures until the sealing material 5 overflows from the exhaust hole 32 of the other half pipe clamp structure, indicating that the sealed space has been completely filled and the sealing construction is completed.

[0084] In the related art, in industrial buildings, civil buildings and municipal engineering, the traditional sealing technology and fixing method when the medium pipeline 2 passes through the partition 1 or the floor slab have some significant limitations and problems in terms of sealing, structural stability, stress state and construction process.

[0085] Taking sealing as an example, Figure 1 and 2As shown in the traditional through-interlayer structure in the related art, the displacement caused by the superimposed weight of the medium pipes will form a second leakage channel XL2. And in the process of installing the sealing material, an open filling sealing process is usually adopted, that is, the sealing material, such as flexible filler and waterproof paste, is directly filled in the gap between the pipe and the interlayer to achieve the sealing effect. However, the above-mentioned open filling method is difficult to ensure the uniformity and density of the sealing material filling, and it is easy to have problems such as bubbles and gaps, which reduces the sealing effect. In the process of installing the sealing material, there is no upper and lower constraint device structure in the sealing space, and the construction operators cannot fully fill the flexible material densely, so that the sealing material is in a three-stress state, and XL2 gaps and honeycomb pores are often generated, causing leakage risks. At the same time, for the uneven settlement deformation of buildings and structures and the working vibration and distortion of the medium pipeline 2 and other on-site environments, the bonding performance of the waterproof paste between the medium pipeline and the embedded casing is limited, and the sealing effect is limited.

[0086] Taking structural stability and stress state as an example, traditional pipe fixing brackets are usually used in related technologies to achieve positioning constraints in the horizontal direction. However, traditional brackets can only perform positioning constraints in the horizontal direction and cannot effectively cope with the weight and external forces of the vertical pipeline, causing the entire pipeline to be in a "compressed" state and prone to bending and deformation. In addition, because the traditional bracket design does not take into account factors such as vibration, pressure swing, and water hammer that may occur when the medium pipeline is working, long-term use may cause sealing failure. At the same time, for longer or heavier pipelines, an additional bottom support structure is required, which increases the complexity and cost of construction.

[0087] Taking the construction process as an example, the open-fill process is highly dependent on the construction workers' skills and experience, and the construction quality and efficiency fluctuate greatly. Once the seal fails, the repair process is complicated and time-consuming, and it is often necessary to dismantle part of the structure and re-construct. Therefore, the quality and duration of the above construction process are affected by various factors of "man-machine-material-method-environment", and the construction is difficult and costly.

[0088] In summary, although the existing technology can meet the basic pipeline crossing requirements to a certain extent, it still has obvious deficiencies in terms of sealing, anti-deformation ability, and construction convenience.

[0089] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a crossing pipe assembly, which transforms the construction method of the "open filling" sealing process in the traditional construction field into an "assembled" sealing installation method, and combines the pipe support with the sealing structure to realize an integrated function, and transforms the stress mode of the original pipe from the original "compression" state to the "tension" state, thereby changing its stress state and overcoming the shortcomings of the original standard.

[0090] Furthermore, the pipe-crossing assembly of the present invention has at least the following advantages compared with the related art:

[0091] (1) Improving sealing reliability: By ensuring that at least one of the first half pipe clamp structure 3 and the second half pipe clamp structure 4 is provided with an injection hole 42 and an exhaust hole 32, the sealing material 5 can evenly and fully fill the sealing space. This design avoids the problem of bubbles and gaps that are prone to occur in the traditional "open filling" sealing process, thereby significantly improving the sealing effect.

[0092] At the same time, the use of a pouring construction method instead of the traditional open filling method ensures that the sealing material 5 can completely fill the sealing space, providing a more reliable waterproof sealing performance. In addition, the overall sealing structure has a "flexible" deformation function, thereby further improving the sealing performance.

[0093] (2) Enhanced positioning function: The present invention controls the gripping force on the half pipe clamp structure by tightening the bolts, firmly locks the medium pipeline 2, and applies the weight of the pipeline to the bottom of the first half pipe clamp structure 3, thereby realizing the vertical (Z direction) positioning function. At the same time, the bottom of the first half pipe clamp structure 3 is fixed to the floor slab by a fixing member, providing horizontal (X, Y direction) positioning constraints to ensure that the overall structure is stable and reliable.

[0094] It can be understood that the above structure changes the original traditional fixing bracket method which is limited to horizontal positioning, realizes more comprehensive multi-dimensional positioning, simplifies the installation process and improves the overall stability of the structure.

[0095] (3) Optimizing the stress state of the pipeline: The present invention rationally configures the expansion joint of the pipeline and eliminates the original fixed bracket, so that the stress state of the pipeline changes from "single rod compression" (such as Figure 2 ) into a segmented “tension” state (as shown Figure 5 This method disperses the deadweight and external forces of the pipeline, reduces the risk of sealing failure caused by the overall pipeline bending and deformation, and prolongs the service life of the pipeline system. At the same time, by properly setting the expansion joint, the force at the end of the pipeline segment can be reduced to 0, achieving no bending of the overall pipeline, further enhancing the stability and reliability of the system.

[0096] (4) Simplify the construction process: The present invention adopts an assembled structure and construction method. The entire installation process does not rely on complex on-site operations, which reduces the impact of various factors on "man-machine-material-method-environment", reduces the construction difficulty and cost, and improves construction efficiency. In addition, the overall structure can realize a standardized product series, which is convenient for large-scale production and application, and ensures the consistency of construction quality.

[0097] In summary, the crossing pipe assembly of the present invention not only solves the problems of poor sealing, poor flexibility, unstable positioning, unreasonable pipe force and so on in the prior art, but also provides a more efficient, reliable and easy-to-operate solution through innovative design and construction methods, which is particularly suitable for pipe crossing needs in industrial buildings, civil buildings and municipal engineering.

[0098] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, a first Haff chassis 33 is provided at one end of the first Haff pipe clamp structure 3 facing the partition 1, and the first Haff chassis 33 is arranged around the first Haff pipe and fixed on the first side surface 11 of the partition 1. A second Haff chassis 43 is provided at one end of the second Haff pipe clamp structure 4 facing the partition 1, and the second Haff chassis 43 is arranged around the second Haff pipe and fixed on the second side surface 12 of the partition 1.

[0099] Among them, the first Haff chassis 33 and the second Haff chassis 43 jointly block the sealing space, that is, the first Haff chassis 33 and the second Haff chassis 43 work together to completely block the sealing space between the medium pipeline 2 and the partition 1, ensuring that the sealing material 5 will not leak, and providing additional support and positioning functions.

[0100] In this way, on the one hand, the first half chassis 33 and the second half chassis 43 jointly block the sealing space to prevent the sealing material 5 from leaking, significantly improving the sealing effect and ensuring the waterproof performance; on the other hand, the wing ring plate also shares part of the weight of the pipeline, changing the original force-bearing mode, making the pipeline in a more reasonable force-bearing state, and reducing the possibility of flexural deformation. At the same time, by fixing the wing ring plate on both sides of the partition 1, more accurate horizontal and vertical positioning is achieved, ensuring the verticality and flatness of the pipeline installation, and improving the long-term operation stability of the system.

[0101] like Figure 3 and Figure 4 As shown, in some specific embodiments, a first Haff chassis 33 is provided at the bottom of the first Haff tube, and the first Haff chassis 33 is fixed to the upper surface of the barrier 1 by chemical anchor bolts 7. A second Haff chassis 43 is provided at the top of the second Haff tube, and the second Haff chassis 43 is fixed to the lower surface of the barrier 1 by chemical anchor bolts 7.

[0102] In this way, the wing ring plate is fixed to both sides of the partition 1 by chemical anchor bolts 7, which provides additional support points, enhances the stability and reliability of the overall structure, and reduces the risk of displacement caused by vibration or external force.

[0103] like Figure 3 and Figure 4As shown, according to some embodiments of the present invention, a first elastic sealing ring 34 is sandwiched between the first half chassis 33 and the partition 1, and / or a second elastic sealing ring 44 is sandwiched between the second half chassis 43 and the partition 1.

[0104] In this embodiment, the first elastic sealing ring 34 and the second elastic sealing ring 44 are respectively sandwiched between the wing ring plate (ie, the first half chassis 33 and the second half chassis 43) and the partition 1 to form a double sealing barrier.

[0105] In this way, the above design not only enhances the sealing performance, but also effectively prevents moisture and external impurities from entering the sealed space, thereby improving the overall waterproof performance.

[0106] On the one hand, the design of the elastic sealing ring can compensate for the processing error of the contact surface of the interlayer 1, ensure the installation accuracy of the vertical verticality of the medium pipeline 2, and further enhance the stability and reliability of the system. On the other hand, the elastic sealing ring can also evenly disperse the pressure between the wing ring plate and the interlayer 1, avoid local stress concentration, extend the service life of the sealing structure, and reduce maintenance requirements.

[0107] In addition, through the buffering effect of the elastic sealing ring, the entire crossing pipe assembly exhibits higher stability and durability when facing external environmental changes (such as temperature changes, vibrations, etc.), ensuring the long-term reliable operation of the system.

[0108] Furthermore, the first elastic sealing ring 34 and / or the second elastic sealing ring 44 are special-shaped elastic sealing rings. Specifically, at least one side surface of the first elastic sealing ring 34 is provided with a serrated contact surface; and / or, at least one side surface of the second elastic sealing ring 44 is provided with a serrated contact surface.

[0109] It can be understood that, on the one hand, the serrated contact surface significantly increases the friction between the elastic sealing ring and the barrier layer 1 or the wing ring plate, making the sealing ring less likely to slide and enhancing the stability of the overall structure. On the other hand, the serrated structure can better fit the tiny unevenness of the surface of the barrier layer 1, ensuring that the sealing ring can form an effective sealing barrier on the irregular surface.

[0110] The serrated contact surface can absorb the slight displacement between the interlayer 1 and the Haff pipe clamp structure to a certain extent, reducing the risk of sealing failure caused by building settlement or vibration. At the same time, the serrated contact surface can provide more contact points, so that the sealing ring fits the surface of the interlayer 1 more closely, thereby improving the sealing performance and preventing moisture and external impurities from entering the sealed space.

[0111] like Figure 3 and Figure 4As shown, according to some embodiments of the present invention, a first elastic sealing sleeve 35 is sandwiched between the first half pipe clamp structure 3 and the medium pipeline 2, and / or a second elastic sealing sleeve 45 is sandwiched between the second half pipe clamp structure 4 and the medium pipeline 2.

[0112] In this embodiment, the first elastic sealing bushing 35 and the second elastic sealing bushing 45 are respectively sandwiched between the Haff pipe clamp structure (ie, the first Haff pipe clamp structure 3 and the second Haff pipe clamp structure 4) and the medium pipeline 2 to form a double sealing barrier.

[0113] In this way, the above design not only enhances the sealing performance, but also effectively prevents moisture and external impurities from entering the sealed space, thereby improving the overall waterproof performance.

[0114] On the one hand, the elastic sealing bushing can effectively absorb the vibration and stress changes generated by the medium pipeline 2 during operation, reducing the risk of sealing failure caused by vibration and ensuring the long-term stable operation of the system. On the other hand, the elastic sealing bushing can evenly disperse the pressure between the Haff pipe clamp structure and the medium pipeline 2, avoiding local stress concentration, extending the service life of the sealing structure and reducing maintenance requirements.

[0115] In addition, through the buffering effect of the elastic sealing bushing, the entire crossing pipe assembly exhibits higher stability and durability when facing external environmental changes (such as temperature changes, vibrations, etc.), ensuring the long-term reliable operation of the system.

[0116] like Figure 1 and Fig. 9 As shown, further, a plurality of first serrated rings 351 are formed on the inner circumferential wall of the first elastic sealing sleeve 35, and the plurality of first serrated rings 351 are all arranged around the outer circumferential wall of the medium pipe 2 and are arranged at intervals along its axial direction, and / or, a plurality of second serrated rings are formed on the inner circumferential wall of the second elastic sealing sleeve 45, and the plurality of second serrated rings are all arranged around the outer circumferential wall of the medium pipe 2 and are arranged at intervals along its axial direction.

[0117] It can be understood that the multiple serrated rings significantly increase the friction and contact points between the elastic sealing bushing and the medium pipeline 2, so that the medium pipeline 2 is more firmly held and the stability of the overall structure is improved. At the same time, the serrated ring can better adapt to the small radial displacement of the medium pipeline 2, ensuring that good sealing performance can be maintained even in the presence of eccentricity or vibration.

[0118] It is important to note that each serration ring provides an additional sealing barrier, further enhancing the sealing effect and preventing media leakage, especially under vibration, pressure swing and water hammer phenomena generated during pipeline operation.

[0119] As for the arrangement of the sawtooth rings: since the multiple sawtooth rings are arranged at intervals in the axial direction, the pressure between the Haff pipe clamp structure and the medium pipeline 2 can be evenly distributed, avoiding local stress concentration and extending the service life of the sealing structure. The above design can also effectively absorb the vibration of the medium pipeline 2 in the axial direction, reduce the risk of sealing failure caused by vibration, and ensure the long-term stable operation of the system.

[0120] In this way, the plurality of first sawtooth rings 351 and the second sawtooth rings are respectively arranged around the outer peripheral wall of the medium pipeline 2, forming a multiple sealing barrier, significantly enhancing the sealing effect and preventing medium leakage. At the same time, the plurality of sawtooth rings are arranged at intervals in the axial direction, which can evenly disperse the pressure between the Haff pipe clamp structure and the medium pipeline 2, avoid local stress concentration, extend the service life of the sealing structure, and reduce maintenance requirements.

[0121] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the interlayer 1 is a floor, the first half pipe clamp structure 3 is fixed on the upper surface of the floor, and an exhaust hole 32 extending in the up-down direction is formed in the first half pipe clamp structure 3. The second half pipe clamp structure 4 is fixed on the lower surface of the floor, and an injection hole 42 extending in the up-down direction is formed in the second half structure.

[0122] In this embodiment, the exhaust hole 32 in the first half pipe clamp structure 3 is used to exhaust the air or other gas in the sealed space to ensure that the sealing material 5 can fully fill the sealed space and avoid the generation of bubbles and gaps. The injection hole 42 in the second half pipe clamp structure 4 is used to inject the sealing material 5 (such as silicone sealant or fireproof foaming agent) to ensure that the sealing material 5 can evenly and completely fill the sealed space.

[0123] It can be understood that the present invention achieves efficient filling of the sealing material 5 by setting the exhaust hole 32 in the first half pipe clamp structure 3 on the upper surface of the floor slab and setting the injection hole 42 in the second half pipe clamp structure 4 on the lower surface of the floor slab. This design ensures that the sealing material 5 is filled from bottom to top until the sealing material 5 appears in the exhaust hole 32, ensuring that the sealed space is completely filled without bubbles and gaps.

[0124] At the same time, this design simplifies the construction process, reduces the reliance on complex on-site operations, and improves construction efficiency. Construction personnel only need to inject the sealing material 5 from one position and observe the exhaust situation at another position to complete the sealing construction. In addition, the exhaust holes 32 and injection holes 42 extending in the vertical direction ensure that the sealing material 5 can be evenly distributed in the entire sealed space, providing double sealing protection and significantly improving the sealing effect and waterproof performance.

[0125] For example Figure 3 and Figure 4 As shown, two exhaust holes 32 are provided in the first half pipe clamp structure 3, and the two exhaust holes 32 are respectively located on two opposite sides of the medium pipeline 2; and two injection holes 42 are provided in the second half pipe clamp structure 4, and the two injection holes 42 are respectively located on two opposite sides of the medium pipeline 2.

[0126] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the pipe penetration assembly further includes a wall sleeve 6.

[0127] The wall sleeve 6 is inserted into the partition 1 and is provided with a plurality of wing ring fixing plates 61, which are arranged at intervals along the axial direction of the wall sleeve 6 and are all arranged around its outer peripheral wall, and the wing ring fixing plates 61 are fixedly connected to the structural steel bars of the partition 1. The medium pipeline 2 is inserted into the wall sleeve 6, and a sealed space is defined between the outer peripheral wall of the medium pipeline 2 and the inner peripheral wall of the wall sleeve 6.

[0128] In this way, on the one hand, the wing ring fixing plates 61 are arranged at intervals along the axial direction of the wall sleeve 6, which can evenly disperse the pressure from the partition 1, avoid local stress concentration, and extend the service life of the wall sleeve 6. On the other hand, the wing ring fixing plates 61 are fixedly connected to the structural steel bars of the partition 1, which significantly enhances the stability of the wall sleeve 6, ensures its position in the partition 1 is accurate, and reduces installation errors.

[0129] At the same time, the wing ring fixing plate 61 provides an additional support point for the wall sleeve 6, especially during the pouring process of the partition 1, to ensure that the wall sleeve 6 will not be displaced or deformed.

[0130] Furthermore, the wing ring fixing plate 61 includes a first wing ring plate 62, an intermediate wing ring plate 63 and a second wing ring plate 64; wherein the first wing ring plate 62 is fixed to the first side surface 11 of the partition 1 by a chemical anchor 7, the second wing ring plate 64 is fixed to the second side surface 12 of the partition 1 by a chemical anchor 7, and the intermediate wing ring plate 63 is located between the first wing ring plate 62 and the second wing ring plate 64.

[0131] For example Figure 3 As shown, the first wing ring plate 62 and the first half chassis 33 are both fixed on the upper surface of the floor slab, and the first half chassis 33 is located above the first wing ring plate 62 and is isolated from the first wing ring plate 62 by a first elastic sealing ring 34, and the chemical anchor 7 passes through the first half chassis 33 and the first wing ring plate 62 from top to bottom in sequence and is finally fixed in the floor slab.

[0132] The second wing ring plate 64 and the second Hough chassis 43 are both fixed on the upper surface of the floor slab, and the second Hough chassis 43 is located above the second wing ring plate 64 and is isolated from the second wing ring plate 64 by a second elastic sealing ring 44, and the chemical anchor 7 passes through the second Hough chassis 43 and the second wing ring plate 64 from top to bottom in sequence and is finally fixed in the floor slab.

[0133] According to some embodiments of the present invention, a reserved wall-penetrating hole is provided at the position where the wall-penetrating sleeve 6 is pre-embedded in the partition 1, and on the basis of the conventional distribution reinforcement in the vertical and horizontal directions of the partition 1, reinforcing ribs (preferably an angle of 45°) are arranged around the reserved wall-penetrating hole at an angle to the conventional distribution reinforcement.

[0134] In this embodiment, a reserved through-wall hole is set at a predetermined position of the interlayer 1 for pre-embedded wall sleeve 6. The size of the hole should be reasonably determined according to the outer diameter of the wall sleeve 6 and the construction error to ensure that the wall sleeve 6 can be smoothly installed. Conventional distribution bars in the vertical direction (vertical direction) and the horizontal direction (horizontal direction) are usually provided inside the interlayer 1. These steel bars are used to enhance the overall structural strength and stability of the interlayer 1. Reinforcement bars are arranged around the reserved through-wall hole at an angle of 45° to the conventional distribution bars. The design of this reinforcement bar can significantly improve the local strength around the through-wall hole and prevent stress concentration problems caused by the passage of pipelines.

[0135] In this way, the oblique arrangement of the reinforcement ribs can effectively prevent potential cracks from expanding outward from the through-wall holes, thereby improving the overall durability and reliability of the interlayer 1. Moreover, the obliquely arranged reinforcement ribs not only enhance the local strength of the interlayer 1, but also improve the seismic performance of the interlayer 1, which is particularly important in earthquake-prone areas or projects with high seismic requirements for buildings.

[0136] For example, if the reinforcement ribs are arranged at an angle of 45°, the reinforcement ribs can effectively disperse the pressure from the wall sleeve 6 and its surrounding area during the pouring process of the interlayer 1, avoid local stress concentration, and enhance the structural strength around the wall hole.

[0137] A construction method for a pipe crossing assembly is provided below with reference to the accompanying drawings. The construction method can be applied to the pipe crossing assembly described in the embodiment of the first aspect of the present invention.

[0138] like Fig.10 As shown, specifically, the construction method includes:

[0139] Step S1, pre-embed a wall sleeve 6 with a wing ring fixing plate 61 at a predetermined position of the interlayer 1, and fix the wing ring fixing plate 61 to the structural steel bars of the interlayer 1;

[0140] Step S2, inserting the medium pipeline 2 into the pre-buried wall bushing 6 to perform preliminary positioning of the medium pipeline 2;

[0141] Step S3, installing the first Hough pipe clamp structure 3 on the medium pipeline 2, and fixing the first Hough pipe clamp structure 3 on the surface of the first side of the partition 1;

[0142] Step S4, on the premise that the medium pipeline 2 is fixed between two adjacent partitions 1, a vibration-damping corrugated compensator is arranged and installed on the medium pipeline 2;

[0143] Step S5, installing the second Hough pipe clamp structure 4 on the medium pipeline 2, and fixing the second Hough pipe clamp structure 4 on the surface of the second side of the partition 1;

[0144] Step S6 , injecting the sealing material 5 into the injection hole 42 into the sealed space until the sealing material 5 overflows from the exhaust hole 32 .

[0145] Further, the step of installing the first Hough pipe clamp structure 3 on the medium pipeline 2 and fixing the first Hough pipe clamp structure 3 on the surface of the first side of the partition 1 specifically includes:

[0146] The two first half covers 31 are locked on the outer peripheral wall of the medium pipeline 2 by the first fastening bolts 36 , and the first half base 33 and the first wing ring plate 62 are fixed on the first side surface 11 of the partition 1 by chemical anchor bolts 7 in sequence.

[0147] Further, the step of installing the second Hough pipe clamp structure 4 on the medium pipeline 2 and fixing the second Hough pipe clamp structure 4 on the surface of the second side of the partition 1 specifically includes:

[0148] The two second half covers 41 are locked on the outer peripheral wall of the medium pipeline 2 by the second fastening bolts 46 , and the second half base 43 and the second wing ring plate 64 are fixed on the second side surface 12 of the partition 1 by chemical anchor bolts 7 in sequence.

[0149] A specific embodiment of the pipe crossing assembly and the construction method thereof of the present invention is given below.

[0150] The engineering application of the above-mentioned crossing pipe assembly and its construction method is described by taking a cement plant as an example. The cement plant is located in East Asia, with complex geological conditions, high groundwater level, high seepage pressure, and often accompanied by ground surge. There is an industrial circulating water system, a kiln head workshop adjacent to the crushing workshop, multiple grate coolers in the workshop, and a medium pipeline 2 with a diameter of DN = 150mm. A multi-story floor structure is required inside the vertical plant, and the floor is a cast-in-place reinforced concrete structure, and each floor is required to have a waterproof function.

[0151] The medium pipeline 2 of the cement plant has the following characteristics: it has obvious temperature changes, and the pipeline has large radial and longitudinal distortions; the medium in the pipeline belongs to a forced circulation system, and is accompanied by working vibrations, pressure swings, and water hammer knocking phenomena generated by the circulation pump. Since the medium pipe diameter is large, the pipeline is relatively long, the superimposed weight is large, and a supporting structure cannot be set at the bottom of the pipeline, and the building structure has working vibration phenomena. According to the lessons learned from the construction of the first phase project using the national standard atlas, it was decided to adopt the half structure and construction method of the present invention. The focus is on solving the weight decomposition of the overall medium pipeline 2, the working vibration damping isolation function, the three positioning functions between the medium pipeline 2 and the floor slab, and the waterproof sealing function at the intersection. Practice has proved that the waterproof sealing effect of the structure is significant and can meet the harsh working environment of the heavy industrial plant.

[0152] like Figures 1 to 10 As shown, the construction method of the above-mentioned crossing pipeline assembly includes the following steps:

[0153] (1) Preparation work before construction: Determine the position in the interlayer 1 (such as the floor slab) that needs to be penetrated, and make detailed design plans, including the size, position and reinforcement arrangement of the wall sleeve 6. Prepare the required materials according to the design requirements: wall sleeve 6, wing ring fixing plate 61, medium pipeline 2, half pipe clamp structure (including half cover, fastening bolts), chemical anchor bolts 7, sealing materials 5, vibration-damping corrugated compensator, etc.

[0154] Holes for penetrating the wall and the floor are reserved at predetermined positions of the interlayer 1 to ensure that the hole size is suitable for the installation of the wall sleeve 6. Reinforcement ribs are arranged at a 45° angle around the reserved wall holes to enhance local strength, prevent crack expansion and improve seismic performance.

[0155] (2) Pre-embed the wall sleeve 6: Pre-embed the wall sleeve 6 with the wing ring fixing plate 61 in the reserved wall hole. The wing ring fixing plate 61 is fixedly connected to the structural steel bar of the interlayer 1 to ensure the accurate positioning of the wall sleeve 6 in the interlayer 1.

[0156] In this way, a stable passage can be provided for the subsequent medium pipeline 2 to pass through, while ensuring that the wall sleeve 6 will not be displaced or offset.

[0157] (3) Preliminary positioning of the medium pipeline 2: Insert the medium pipeline 2 into the pre-buried wall sleeve 6, and perform preliminary positioning of the medium pipeline 2 to ensure that its verticality and flatness meet the requirements. The purpose is to ensure that the medium pipeline 2 passes through the partition 1 smoothly and provide an accurate foundation for subsequent installation.

[0158] (4) Installing the first half pipe clamp structure 3: Installing the first half pipe clamp structure 3 on the medium pipeline 2 and fixing it on the first side surface 11 of the partition 1. Specifically, the process includes: using the first fastening bolts 36 to lock the two first half covers 31 on the outer peripheral wall of the medium pipeline 2, and fixing the first half chassis 33 and the first wing ring plate 62 on the first side surface 11 of the partition 1 in turn through the chemical anchor bolts 7.

[0159] In this way, vertical and horizontal constraints can be provided to ensure the stability and sealing of the medium pipeline 2 on one side of the partition 1.

[0160] (5) Install a vibration-damping corrugated compensator: Install a vibration-damping corrugated compensator upstream of the medium pipeline 2 to absorb the stress changes caused by the working vibration and thermal expansion and contraction of the pipeline. In this way, the pipeline system can be protected from mechanical damage and the normal operation of the system can be maintained.

[0161] (6) Installing the second half pipe clamp structure 4: Install the second half pipe clamp structure 4 on the medium pipeline 2 and fix it on the second side surface 12 of the partition 1. Specifically, the process includes: using the second fastening bolts 46 to lock the two second half covers 41 on the outer peripheral wall of the medium pipeline 2, and fixing the second half chassis 43 and the second wing ring plate 64 on the second side surface 12 of the partition 1 in turn through the chemical anchor bolts 7.

[0162] In this way, vertical and horizontal constraints on the other side can be provided to ensure the stability and sealing of the medium pipeline 2 on both sides of the partition 1.

[0163] (7) Injecting sealing material 5: Inject sealing material 5 (such as silicone sealant or fireproof foaming agent) into injection hole 42 until sealing material 5 overflows from exhaust hole 32. In this way, it can be ensured that the sealing space is completely filled, bubbles and gaps are avoided, and good waterproof and sealing effects are ensured.

[0164] (8) Inspection: Check whether the sealing material 5 fills the sealing space evenly to ensure that there are no bubbles or gaps. Confirm that the sealing material 5 overflows from the exhaust hole 32, indicating that the sealing space has been completely filled.

[0165] At the same time, check whether the first half pipe clamp structure 3 and the second half pipe clamp structure 4 are firmly fixed on both sides of the partition 1. Confirm that the torque of all fastening bolts and chemical anchor bolts 7 meets the design requirements to ensure structural stability.

[0166] In addition, the entire crossing pipe assembly is subjected to pressure testing or other applicable functional tests to ensure that the system's sealing and functionality meet the design standards.

[0167] (9) Final acceptance: After all inspections and tests are completed, a final acceptance is carried out to ensure that the construction quality meets the relevant specifications and standards.

[0168] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
