Description

Technical Field

[0001] This invention belongs to the field of municipal pipeline engineering construction, specifically relating to a sealing installation device for pipelines buried at greater depths and a construction method for pipelines buried at greater depths. Background Technology

[0002] Sewage pumping stations are often buried at considerable depths, typically exceeding 16 meters. At these depths, the geology contains a significant amount of silt and sand, along with abundant groundwater and intercalary water. Leaks in the sewage pipes can cause structural subsidence, severely compromising the safe operation of the pumping station. Furthermore, the deep burial of the pipes in sewage pumping stations results in high repair costs. Therefore, leak-proofing of the pipes in sewage pumping stations is of paramount importance.

[0003] Since sewage pumping stations serve as collection points for sewage in a region, the sewage flow rate reaches its peak at certain times. At this point, the impact force of the sewage severely tests the pipeline's leak-proof capabilities. Impurities carried in the sewage also affect the pipeline's corrosion resistance, impacting its leak-proof performance. Ensuring leak-proof performance during the construction of deeply buried pipelines, such as those used in sewage pumping stations, is both a challenge and a key focus.

[0004] One of the commonly used connection methods for existing pipelines is the socket joint connection, with a sealing ring used at the joint. Because sewage pumping stations are buried at great depths, pipelines need to withstand significant water flow, impact, and mechanical forces, leading to issues such as pipe joint detachment and leaks. Furthermore, during the connection process between upstream and downstream pipes, the sealing ring can sometimes be damaged or even detach, causing leaks and compromising the quality of pipelines buried at great depths in sewage pumping stations.

[0005] The sealing rings for the interfaces of existing sewage pumping station pipes buried at greater depths are usually installed manually. This is not only slow, but the sealing effect of the pipes also depends on the installation skills of the workers, which is not conducive to preventing leakage of sewage pumping station pipes buried at greater depths. Summary of the Invention

[0006] The main objective of this invention is to provide a sealing installation device and a construction method for deep-buried pipelines. The installation device can quickly install sealing rings for deep-buried pipelines, improving construction efficiency; the construction method can improve the sealing performance of deep-buried pipelines and enhance the sealing and leak-proof effect of deep-buried pipelines.

[0007] The technical solution adopted in this invention is:

[0008] A sealing structure for pipelines buried at a relatively deep depth is generally annular and includes two layers of sealing rubber rings. Between the two layers of sealing rubber rings are multiple metal rubber rings with a certain degree of deformation resistance. The multiple metal rubber rings are arranged in parallel and are connected to the two layers of sealing rubber rings respectively.

[0009] A further improvement involves shallow grooves on both layers of sealing rings, with nylon threads inside the grooves connecting the two layers. Polysulfide sealant is applied to the nylon threads. By incorporating shallow grooves, nylon threads, and polysulfide sealant, the pipe's sealing performance is significantly improved. The polysulfide sealant exhibits excellent adhesion, continuity, and good airtightness and waterproofing under expansion, contraction, vibration, and temperature changes, resulting in a superior sealing effect.

[0010] A further improvement is that the two sealing rings are hydrogenated nitrile rubber rings, which gives the sealing structure good sealing and corrosion resistance.

[0011] The present invention also provides a sealing installation device for a deep-buried pipeline for installing the sealing structure for the above-mentioned deep-buried pipeline, which includes an operating column with a circular cross-section, an operating handle, and multiple installation mechanisms; the diameter of the operating handle is larger than the diameter of the deep-buried pipeline, and the operating handle is connected to the operating column; the multiple installation mechanisms are arranged around the operating column.

[0012] Each installation mechanism includes a support, an elastic element, and a top support; the support is mounted on the operating column; the elastic element is wrapped around the support in a figure-eight shape; there are two top supports, one at each end of the elastic element; the top supports are equipped with a sealing structure for pipes buried at greater depths.

[0013] The operating column extends into the deeper pipe, and the elastic element is squeezed inward to exert a certain outward stress. When the top support reaches the rubber ring groove in the deeper pipe, the sealing structure of the deeper pipe on the top support is pressed into the rubber ring groove under the action of the elastic element.

[0014] A further improvement is that the elastic element is a copper sheet to ensure that the elastic element has good elasticity.

[0015] A further option is that the top support includes a cylinder and a cone located on the cylinder, which facilitates the installation of a sealing structure for pipes buried at greater depths.

[0016] The present invention also provides a method for constructing pipelines with deep burial depth. This method employs the aforementioned sealing structure and sealing installation device for pipelines with deep burial depth, and specifically includes the following steps:

[0017] 1) Prepare sealing structures for pipelines buried at greater depths;

[0018] 2) Fabricate sealing installation devices for pipelines buried at greater depths;

[0019] 3) Install the sealing structure for the deeper buried pipe from step 1) onto the top support of the sealing installation device for the deeper buried pipe from step 2); hold the operating handle and slowly move the operating column into the deeper buried pipe. After the sealing structure for the deeper buried pipe reaches the rubber ring groove on the deeper buried pipe, the top support will push the sealing structure for the deeper buried pipe into the rubber ring groove under the outward force of the elastic element; after the sealing structure for the deeper buried pipe slides into the rubber ring groove, pull the operating column outward.

[0020] 4) Repeat step 3) to continue installing the sealing structure for the deeper buried pipe in the other rubber ring grooves of the deeper buried pipe;

[0021] 5) Laying a layer of crushed stone and fine sand under the location where a deep-buried pipe is to be installed or where a deep-buried pipe is to be inserted can ensure the anti-leakage effect and the resistance to deformation.

[0022] A standard cylindrical sealing ring is installed at the front end of the buried pipe. The pipe to be inserted into the buried pipe is then connected to form a complete pipe. The standard cylindrical sealing ring seals along the length of the pipe, while the buried pipe is sealed vertically using a sealing structure (i.e., the two sealing rings expand and contract under the action of the intermediate metal ring to press against the outer walls of both the buried pipe and the pipe to be inserted, thus sealing the pipe tightly). With this multi-layered sealing, the overall sealing and leak-proof effect of the pipe is greatly improved.

[0023] 6) Install reinforcing bars (made of steel bars with a diameter of 12mm) on the upper part of the overall pipeline; install a turbulence generating structure on the overall pipeline to generate turbulence; when the water flows through the turbulence generating structure, turbulence can be generated, which can partially eliminate the problem of excessive impact force when the sewage flow rate is at its peak; at the same time, when the flow rate is small, the turbulence generating structure will not have a significant impact on the sewage flow.

[0024] 7) Concrete foundation is poured at the bottom of the overall pipeline; pentagonal encapsulation is applied to the top of the overall pipeline. The pentagonal encapsulation distributes the stress more evenly than the traditional method, which can better prevent pipeline leakage.

[0025] 8) A flexible joint is installed at the front of the overall pipeline. When groundwater is abundant, the pipeline will shift due to groundwater fluctuations. The flexible joint can effectively counteract the structural shift caused by groundwater fluctuations, thus ensuring the anti-leakage effect. A basket grid is installed at the front of the overall pipeline. The basket grid can continuously filter the water, improve water quality, and ensure that the pipeline joints are not easily corroded. A groove is installed at the front of the overall pipeline. This groove is connected to the overall pipeline. After turbulence is generated, some impurities in the sewage will settle due to the turbulence and enter the groove connected to the pipeline. The groove can clean the sewage impurities left in the groove in time.

[0026] A further embodiment is that the turbulence generating structure includes an annular protrusion placed inside the integral pipe and an enlarged pipe connected to the annular protrusion;

[0027] The anchoring includes horizontal anchoring bars and vertical anchoring bars connected to the horizontal anchoring bars; there are multiple horizontal anchoring bars, which are evenly arranged along the circumference of the pipe, and each horizontal anchoring bar is set along the overall length of the pipe; there are multiple vertical anchoring bars, with a spacing of 1200mm between adjacent vertical anchoring bars, and they are set perpendicular to the length of the pipe.

[0028] The lower end of the vertical reinforcing bar is provided with a hook, and the hook is placed inside the concrete foundation.

[0029] The beneficial effects of this invention are as follows:

[0030] By employing two layers of sealing rings and placing a metal ring (metal-rubber sealing ring) between the two layers of sealing rings, the sealing structure for pipelines with deeper burial depths has good sealing performance in the vertical direction of the pipeline, greatly improving the pipeline's sealing performance.

[0031] The specially structured sealing installation device for deep-buried pipelines avoids damage and deformation of the sealing ring during construction, ensuring the pipeline's leak-proof effect.

[0032] The circular operating column is designed to fit the pipe, facilitating the installation of the sealing structure;

[0033] The use of sealing installation devices for deeply buried pipelines greatly improves the efficiency of sealing ring installation and construction efficiency.

[0034] Multiple sealing rings are installed during pipe connection to prevent damage and deformation of the sealing rings during construction, thus ensuring the effectiveness of leak prevention.

[0035] By installing reinforcing bars at the top of the pipe and enclosing it in a pentagonal shape, the problem of concrete pipes easily shifting and leaking can be solved; by promptly laying a layer of crushed stone and fine sand at the bottom of the pipe, the seepage prevention effect and deformation resistance can be ensured.

[0036] By incorporating turbulence-generating structures and flexible joints, the impact of groundwater fluctuations on pipelines can be reduced, and the pipelines' resistance to deformation can be improved.

[0037] Impurities in the sewage are promptly removed by grooves and basket grilles, ensuring that pipe joints and connections are not corroded.

[0038] This invention ensures the seepage prevention effect of underground sewage pipes, greatly improves the safety and stability of the pipes, and has promotional value in the construction of ultra-deep pipes, pipes with frequent groundwater fluctuations, and pipes with high sealing requirements.

[0039] This invention can improve the anti-leakage, anti-impact, and anti-corrosion performance of pipelines;

[0040] Sealing installation devices for deeply buried pipelines can effectively solve the problems of inconvenient installation of sealing rings, easy damage during installation, and poor sealing performance. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] Example 1

[0051] A sealing structure 1 for deeply buried pipelines is generally annular, comprising two layers of sealing rings 1.1. Between the two layers of sealing rings 1.1 are multiple metal rings 1.2 with a certain degree of deformation resistance. The multiple metal rings 1.2 are arranged in parallel, with one end connected to the first layer of sealing rings 1.1 and the other end connected to the second layer of sealing rings 1.1. Both the first and second layers of sealing rings have shallow grooves 1.3, within which are placed nylon threads 1.4. One end of the nylon thread 1.4 is connected to the first layer of sealing rings 1.1, and the other end is connected to the second layer of sealing rings 1.1. The nylon thread 1.4 is coated with polysulfide sealant 1.5. The use of shallow grooves 1.3, nylon threads 1.4, and polysulfide sealant 1.5 significantly improves the sealing performance. Polysulfide sealant 1.5 exhibits good adhesion continuity, excellent airtightness and waterproofness under expansion, contraction, vibration and temperature changes, resulting in a better sealing effect for the sealing structure. In this embodiment, the two sealing rings 1.1 are hydrogenated nitrile butadiene rubber sealing rings, which provide the sealing structure with good sealing and corrosion resistance.

[0052] During use, the first and second sealing rings of the two sealing rings 1.1 are tightly attached to the inner and outer pipe walls of the socket joint under the action of the metal ring 1.2 to achieve a seal.

[0053] Example 2

[0054] A sealing installation device 2 for a deeply buried pipeline, used for installing the sealing structure 1 for a deeply buried pipeline in Embodiment 1, includes an operating column 2.1 with a circular cross-section, an operating handle 2.2, and multiple installation mechanisms. The diameter of the operating handle 2.2 is larger than the diameter of the deeply buried pipeline 3, and the operating handle 2.2 is connected to the operating column 2.1. The multiple installation mechanisms are arranged around the operating column 2.1. In this embodiment, each installation mechanism includes a support 2.3, an elastic element 2.4, and a top support 2.5. The support 2.3 is mounted on the operating column 2.1; the elastic element 2.4 is wrapped around the support 2.3 in a figure-eight shape; there are two top supports 2.5, respectively located at both ends of the elastic element 2.4. In use, the sealing structure 1 for the deeply buried pipeline is installed on the top support 2.5.

[0055] In this embodiment, the elastic element 2.4 is a copper sheet to ensure that the elastic element has good elasticity.

[0056] To facilitate the installation of sealing structures 1 for pipelines buried at greater depths, the top support 2.5 includes a cylinder and a cone located on the cylinder.

[0057] During installation, the operating column 2.1 is slowly inserted into the deeper buried pipe 3. The elastic element 2.4 is squeezed inward under force and has a certain outward stress. When the top support 2.5 reaches the rubber ring groove 4 in the deeper buried pipe 3, the sealing structure 1 of the deeper buried pipe on the top support 2.5 is pressed into the rubber ring groove 4 under the action of the elastic element 2.4.

[0058] Example 3

[0059] A method for constructing pipelines with deep burial depth, comprising the following steps: (1) The sealing structure for pipelines with deep burial depth of Example 1 and the sealing installation device for pipelines with deep burial depth of Example 2.

[0060] 1) Prepare the sealing structure 1 for the deep-buried pipeline in Example 1. This sealing structure has good sealing and corrosion resistance. It includes two layers of sealing rings 1.1. The two layers of sealing rings 1.1 are connected by a metal ring 1.2 with a certain deformation resistance. A shallow groove 1.3 is set in the two layers of sealing rings 1.1. Nylon filaments 1.4 are pre-embedded in the shallow groove 1.3 in the early production stage. During installation, a layer of polysulfide sealant 1.5 should be applied to the nylon filaments 1.4 in advance. This material has good adhesion, continuity, good airtightness and waterproofness under expansion, contraction, vibration and temperature changes.

[0061] 2) Fabricate the sealing installation device 2 for the deep-buried pipeline in Example 2.

[0062] 3) Before using the sealing structure 1 for deeply buried pipelines, remove surface dust and attachments, and apply a layer of primer. Similarly, apply a layer of primer to the inside of the deeply buried pipeline 3. Install the sealing structure 1 from step 1) onto the top support 2.5 of the sealing installation device 2 for deeply buried pipelines from step 2). Holding the operating handle 2.2, slowly move the operating column 2.1 into the deeply buried pipeline 1. Once the sealing structure 1 reaches the rubber ring groove 4 on the deeply buried pipeline 3, the top support 2.5, under the outward force of the elastic element 2.4, pushes the sealing structure 1 into the rubber ring groove 4. After the sealing structure 1 slides into the rubber ring groove 4, pull the operating column 2.1 outward.

[0063] 4) Repeat step 3) to continue installing the sealing structure 1 for the deeper buried pipe in the other rubber ring grooves 4 of the deeper buried pipe 3 until two sealing rubber rings are installed on the inner wall of the deeper buried pipe 3.

[0064] 5) Before pipeline installation, surveying and setting out, excavation and treatment of the foundation pit should be carried out. At the bottom of the foundation where a deep-buried pipeline is to be installed or where a deep-buried pipeline is to be inserted, a layer of crushed stone 7 and a layer of fine sand 8 should be laid to ensure the anti-seepage effect and the resistance to deformation. The crushed stone layer 7 is composed of gravel of different sizes. The width of the crushed stone layer 7 should extend 0.5 meters to each side depending on the size of the pipeline. A layer of fine sand 8 should be laid on top of the crushed stone layer 7. Both layers need to be compacted in layers to ensure that the bearing capacity of the foundation meets the requirements.

[0065] Near the pipe opening at the front of the deeper buried pipe 3, a ring of ordinary cylindrical sealing rubber is installed. The pipes are aligned, and the deeper buried pipe to be inserted is inserted into the deeper buried pipe 3 to connect the deeper buried pipe and the pipe to be inserted, forming an integral pipe 6. The ordinary cylindrical sealing rubber ring seals along the length of the pipe, and the deeper buried pipe is sealed along the vertical direction of the pipe using the sealing structure 1 (that is, the two layers of sealing rubber rings 1.1 will expand and contract under the action of the middle metal rubber ring 1.2 to abut against the outer wall of the deeper buried pipe 3 and the pipe to be inserted, sealing the pipe tightly). With the sealing effect of the three layers of sealing rings, the overall sealing and anti-leakage effect of the pipe is greatly improved.

[0066] A reinforcing bar 9 (made of steel bars with a diameter of 12mm) is installed on the upper part of the integral pipe 6; the reinforcing bar 9 includes horizontal reinforcing bars 9.1 and vertical reinforcing bars 9.2 connected to the horizontal reinforcing bars 9.1; there are 7 horizontal reinforcing bars 9.1, which are evenly arranged along the circumference of the integral pipe 6, and each horizontal reinforcing bar 9.1 is set along the length of the integral pipe 6; there are multiple vertical reinforcing bars 9.2, with a spacing of 1200mm between adjacent vertical reinforcing bars 9.2, and the vertical reinforcing bars 9.2 are set perpendicular to the length of the integral pipe 6; a hook 9.3 is provided at the lower end of the vertical reinforcing bar 6.

[0067] A turbulence generating structure 10 is provided on the integral pipe 6 to generate turbulence. The turbulence generating structure 10 includes an annular protrusion 10.1 placed inside the integral pipe 6 and an enlarged pipe 10.2 connected to the annular protrusion 10.1. Water flow passing through the turbulence generating structure 10 can generate turbulence. The generation of turbulence can partially eliminate the problem of excessive impact force when the sewage flow rate is at its peak. At the same time, when the flow rate is low, the turbulence generating structure 10 will not have a significant impact on the sewage flow.

[0068] 7) Pour a C15 concrete foundation 11 at the bottom of the overall pipeline 6 in a timely manner. The concrete foundation 11 surrounds the lower half of the overall pipeline 6, and the hook 9.3 is placed inside the concrete foundation. During the pouring process, ensure that the pipeline does not shift or deform. Make a pentagonal enclosure 12 on the top of the overall pipeline 6. The pentagonal enclosure 12 has a more uniform stress distribution than the traditional method, which can better prevent pipeline leakage.

[0069] 8) A flexible joint 13, approximately 300mm in length, is installed at the front of the overall pipeline. When groundwater is abundant, the overall pipeline 6 will shift due to groundwater fluctuations. The flexible joint 13 can effectively counteract this structural shift, ensuring leak-proof performance. A basket grille 14 is installed inside the sewage well 6 at the front end of the overall pipeline 6. The basket grille 14 continuously filters the water, improving water quality and preventing corrosion of the pipeline joints. After turbulence occurs, some impurities in the sewage will settle due to the turbulence and enter the groove connected to the pipeline. These impurities can severely affect the sealing quality of the flexible joint and the junction of the concrete pipe and the spigot. Therefore, a groove 15 is installed at the front of the overall pipeline, connected to the overall pipeline. The groove allows for timely cleaning of sewage impurities left inside. The groove is 500*500mm in size and finished with cement mortar.

[0070] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
