Description

Technical Field

[0001] This utility model relates to the field of large-diameter slurry shield tunneling, and more specifically, to a slurry flushing pipeline structure based on a slurry flushing pump. Background Technology

[0002] A tunnel boring machine (TBM) is a large-scale tunneling equipment integrating mechanical, hydraulic, electrical, fluid control, and automation technologies. It is widely used in underground tunnel construction for subways, railways, highways, and municipal engineering projects. Its core working principle involves a rotating cutterhead cutting through the ground, breaking up the soil, mixing it with mud to form stable support, and carrying away the excavated material, thus achieving safe, efficient, and continuous tunneling operations. Throughout the tunneling process, a mud flushing pump is responsible for delivering high-pressure flushing media to the cutterhead and mud chamber to remove mud buildup on the cutterhead, prevent suction port blockage, and maintain a stable flow field within the chamber. Especially in high-viscosity strata or under conditions of prolonged downtime, the mud flushing pump-driven mud chamber flushing pipeline structure becomes a core component ensuring the normal operation of the TBM.

[0003] Especially during the initial launch of the tunnel boring machine (TBM), considering the diverse clay strata encountered during tunneling, it is necessary to ensure good flushing effects on the slurry chamber and cutterhead. Furthermore, some problems have arisen with the slurry chamber flushing pipeline during TBM operations. Specifically, the original pipeline design has resulted in poor flushing performance, frequent blockages, and even complete blockage of some pipelines. This has led to low flushing efficiency for the slurry chamber and cutterhead, causing mud cake formation on the cutterhead after passing through clay strata, affecting the progress and quality of the entire project. Additionally, uneven flushing has led to the accumulation of excavated soil within the chamber, increasing equipment wear and the failure rate.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a mud and water tank flushing pipeline structure based on a mud flushing pump to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: The mud-water tank flushing pipeline structure based on the mud flushing pump is installed through one side of the cutterhead connecting plate, and the mud-water tank connecting plate is installed on the outside of the cutterhead connecting plate. It includes: a central flushing component, installed on one side of the cutterhead connecting plate; a main slurry inlet component, installed on one side of the mud-water tank connecting plate; a mud-water tank bottom flushing component, installed at the bottom of the main slurry inlet component; and an expansion component, installed between the main slurry inlet component and the mud-water tank bottom flushing component, for increasing the mud-water tank flow rate.

[0007] Furthermore, in order to achieve flushing of the cutterhead, multi-directional three-dimensional flushing of the central area of ​​the cutterhead can be achieved through the action of several connecting pipes and expansion hoses, significantly expanding the flushing coverage area, effectively breaking the static accumulation state of mud on the cutterhead surface, and preventing mud cake formation. The central flushing component includes: a central flushing pipe, located on one side of the cutterhead connecting plate; a cross-shaped pipe, located at one end of the central flushing pipe near the cutterhead connecting plate; several connecting pipes, located on the outside of the cross-shaped pipe; and expansion hoses, located on one side of the connecting pipes and penetrating through the cutterhead connecting plate; the cross-section of the connecting pipes is E-shaped.

[0008] Furthermore, in order to achieve uniform distribution of slurry, a multi-point slurry inlet pattern can be formed under the action of the first and second slurry inlet pipes, which enhances the disturbance capability of the flow field in the slurry tank, improves the slag carrying efficiency, and avoids slag deposition caused by local low flow velocity. The main slurry inlet assembly includes a main slurry inlet pipe set in the middle of one side of the slurry tank connecting plate. The two ends of the main slurry inlet pipe are provided with a first slurry inlet pipe that penetrates the top of the slurry tank connecting plate. The bottom end of the main slurry inlet pipe is symmetrically provided with a second slurry inlet pipe that penetrates the bottom of the slurry tank connecting plate. A gravity-flow slurry pipe that penetrates the bottom of the slurry tank connecting plate is provided on one side of the second slurry inlet pipe.

[0009] Furthermore, in order to achieve flushing of the bottom of the slurry tank, and to enhance the flushing of the dead zone at the bottom of the tank under the action of the flushing connection pipe, and remove the deposited sludge, the slurry tank bottom flushing assembly includes a slurry tank bottom flushing pipe installed at the bottom of the main slurry inlet assembly, and flushing connection pipes that penetrate the slurry tank connection plate are provided at both ends of the slurry tank bottom flushing pipe.

[0010] Furthermore, to ensure the continuous reliability of the flushing function, redundant flushing paths are formed through the cooperation of the expansion connecting pipe and the auxiliary pipe. This ensures the continuous reliability of the flushing function even when the main flushing channel is blocked or the flow is insufficient, avoiding downtime for cleaning due to flushing interruptions. This improves the uniformity and intensity of flushing, enhances the adaptability and reliability of the pipeline structure, significantly reduces the frequency of unplanned cleaning, lowers equipment wear and maintenance costs, and significantly improves the continuous tunneling capability and construction efficiency of the tunnel boring machine under complex geological conditions. The expansion component includes expansion connecting pipes symmetrically arranged on one side of the flushing pipe at the bottom of the slurry chamber and connected to the gravity-flow slurry pipe. A flow-disrupting component is installed at the top of the expansion connecting pipe, and an auxiliary pipe connected to the second slurry inlet pipe is installed at the top of the flow-disrupting component. The flow-disrupting component includes a contraction section at the bottom of the auxiliary pipe, a throat at the bottom of the contraction section, and an expansion section at the bottom of the throat. The contraction section is a conical structure with a gradually decreasing diameter along the direction away from the auxiliary pipe; the expansion section is a conical structure with a gradually increasing diameter along the direction away from the auxiliary pipe.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated arrangement of the central flushing component, the main slurry feed component, the bottom flushing component of the slurry chamber, and the expansion component, not only solves the problem of mud cake easily forming in the center of the cutterhead, making the flushing more uniform and effective, but also removes the accumulated slag on the cutterhead from multiple directions, improving the flushing efficiency and effect on the cutterhead and slurry chamber. It greatly reduces the possibility of mud cake forming in the center of the cutterhead when tunneling in clay strata, avoids insufficient flow of the slurry chamber affecting the slag carrying capacity and causing stagnation, and reduces unnecessary opening of the chamber to clean mud cake and slag accumulation, thereby reducing construction costs and improving tunneling efficiency.

[0012] 2. By expanding the hose and expansion components, this pipeline can be used as a backup for the flushing pipeline in special circumstances. When the original pipeline is not flushing smoothly, it can be opened as a backup pipeline to ensure the flushing flow rate for normal tunneling. This reduces the workload when opening the chamber, shortens the opening time, reduces equipment wear, and thus significantly reduces equipment maintenance costs, extends equipment service life, and improves equipment stability and reliability.

Figures 1-4 As shown, according to an embodiment of the present invention, a mud-water tank flushing pipeline structure based on a mud flushing pump is provided through one side of a cutterhead connecting plate 1. A mud-water tank connecting plate 3 is provided on the outer side of the cutterhead connecting plate 1. The structure includes: a central flushing component 2, disposed on one side of the cutterhead connecting plate 1; a main slurry inlet component 4, disposed on one side of the mud-water tank connecting plate 3; a mud-water tank bottom flushing component 5, disposed at the bottom of the main slurry inlet component 4; and an expansion component 6, disposed between the main slurry inlet component 4 and the mud-water tank bottom flushing component 5, for increasing the mud-water tank flow rate.

[0019] In one embodiment, the central flushing assembly 2 includes: a central flushing pipe 201 disposed on one side of the cutterhead connecting plate 1; a cross-shaped pipe 202 disposed at one end of the central flushing pipe 201 near the cutterhead connecting plate 1; several connecting pipes 203 disposed on the outside of the cross-shaped pipe 202; and a flexible expansion hose 204 disposed on one side of the connecting pipes 203 and penetrating through the cutterhead connecting plate 1; the cross-section of the connecting pipes 203 is E-shaped; under the action of the several connecting pipes 203 and the flexible expansion hose 204, multi-directional three-dimensional flushing of the central area of ​​the cutterhead is realized, significantly expanding the flushing coverage area, effectively breaking the static accumulation state of mud on the cutterhead surface, and preventing the formation of mud cake.

[0020] In one embodiment, the main slurry inlet assembly 4 includes a main slurry inlet pipe 401 located in the middle of one side of the slurry tank connecting plate 3. The main slurry inlet pipe 401 has a first slurry inlet pipe 402 at both ends, penetrating the top of the slurry tank connecting plate 3. A second slurry inlet pipe 403 is symmetrically arranged at the bottom end of the main slurry inlet pipe 401, penetrating the bottom of the slurry tank connecting plate 3. A gravity-flow slurry pipe 404 is arranged on one side of the second slurry inlet pipe 403, penetrating the bottom of the slurry tank connecting plate 3. Under the action of the first slurry inlet pipe 402 and the second slurry inlet pipe 403, a multi-point slurry inlet pattern is formed, enhancing the disturbance capability of the flow field within the slurry tank, improving slag carrying efficiency, and avoiding slag deposition caused by excessively low local flow velocity.

[0021] In one embodiment, the bottom flushing assembly 5 of the mud and water tank includes a bottom flushing pipe 501 of the mud and water tank disposed at the bottom of the main slurry feeding assembly 4. Both ends of the bottom flushing pipe 501 of the mud and water tank are provided with flushing connecting pipes 502 that penetrate the mud and water tank connecting plate 3. Under the action of the flushing connecting pipes 502, the bottom dead zone of the tank can be flushed in a stronger manner to remove the deposited sludge.

[0022] In one embodiment, the aforementioned expansion component 6 includes an expansion connecting pipe 601 symmetrically arranged on one side of the bottom flushing pipe 501 of the mud and water tank and connected to the gravity-flow slurry pipe 404. A turbulence-inducing component 602 is provided at the top of the expansion connecting pipe 601, and an auxiliary pipe 603 communicating with the second slurry inlet pipe 403 is provided at the top of the turbulence-inducing component 602. The turbulence-inducing component 602 includes a contraction section 6021 provided at the bottom of the auxiliary pipe 603, a throat 6022 provided at the bottom of the contraction section 6021, and an expansion section 6023 provided at the bottom of the throat 6022. The contraction section 6021 extends away from the auxiliary pipe 403. The conical structure with a gradually decreasing diameter in the direction of 3; the expansion section 6023 is a conical structure with a gradually increasing diameter in the direction away from the auxiliary pipe 603; under the cooperation of the expansion connecting pipe 601 and the auxiliary pipe 603, a redundant flushing path can be formed, ensuring the continuous and reliable flushing function when the main flushing channel is blocked or the flow is insufficient, avoiding machine shutdown and cleaning due to flushing interruption, improving the uniformity and intensity of flushing, enhancing the adaptability and reliability of the pipeline structure, significantly reducing the frequency of unplanned opening and cleaning, reducing equipment wear and maintenance costs, and significantly improving the continuous tunneling capability and construction efficiency of the tunnel boring machine under complex geological conditions.

[0023] In addition, it should be noted that in order to solve the problem of mud cake easily forming in the center of the cutter head, the center flushing component 2 is connected to the center flushing pump of the cutter head in actual application, and the bottom flushing component 5 of the mud and water tank is connected to the bottom flushing pump of the mud and water tank. The flushing pump is a 160KW horizontal centrifugal pump, which is existing technology and will not be elaborated on here.

[0024] Furthermore, it should be noted that in practical applications, a 65Bar high-pressure ball valve is installed at the connection point between the aforementioned expansion hose 204 and the cutter head connecting plate 1. The opening leads directly to the center area of ​​the cutter head, and an 80Bar high-pressure expansion hose 204 is connected between the ball valve and the hose. A total of four openings are made, effectively creating four direct flushing pipes. Two alloy pipes, expansion connecting pipes 601, are led out from the bottom flushing pipe of the slurry tank and connected to the two gravity-flow slurry pipes 404 in the slurry tank. Two pneumatic ball valves are also present in the middle of the pipes to control the flow. Pressurized and accelerated slurry can flow directly to the slurry tank from this branch pipe, and the ball valve installed is a DN50 direct-flow high-pressure ball valve. The expansion hose 204 is a DN50 high-pressure steel wire hose. The newly added bottom expansion connecting pipe 601 of the slurry tank is a DN150 alloy steel pipe with an elbow. The ball valve added in the middle of the pipeline is a DN150 pneumatic ball valve. The expansion hose 204, the high-pressure ball valve and the expansion connecting pipe 601 are existing technologies, so they will not be elaborated on here.

[0025] Furthermore, it should be noted that in practical applications, the aforementioned expansion component 6 can also be used as a backup for the flushing pipeline under special circumstances. When the original pipeline experiences poor slurry flushing, it can be opened as a backup pipe to ensure the flushing flow rate for normal tunneling, thereby reducing the workload and shortening the opening time. After using this pipeline structure, the flushing effect of the slurry chamber has been significantly improved. By lowering the slurry chamber level and rotating the cutterhead, the mud cake formation on the cutterhead in special geological formations can be observed through the slurry chamber's visualization camera, which shows a significant improvement in the situation. Pipeline blockage during tunneling has essentially disappeared, reducing equipment wear, significantly lowering equipment maintenance costs, extending equipment lifespan, improving equipment stability and reliability, and increasing tunneling efficiency.

[0026] Furthermore, it should be noted that in practical applications, the aforementioned expansion component 6 is made of corrosion-resistant and wear-resistant alloy steel pipeline, which can effectively extend the service life of the pipeline. It can reduce leakage problems caused by pipeline wear and corrosion while flushing with a large flow rate. At the same time, a pressure sensor is added to the expansion component 6, which can determine the slag discharge situation at the bottom of the mud and water chamber by analyzing the real-time pipeline pressure and the outlet pressure and flow rate of the flushing pump. The flushing flow rate at the bottom of the mud and water chamber can be controlled by adjusting the operating speed of the flushing pump through the shield machine control room, so as to prevent stagnation.

[0027] In summary, the core of this pipeline structure is to utilize the adjustable pressurization function of the flushing pump to enhance the flushing of slag and cutterhead, expand the branch pipelines for flushing the central area of ​​the cutterhead, improve the equipment's slag carrying capacity during tunneling, and reduce the possibility of mud cake forming on the cutterhead during tunneling.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, during the tunnel boring machine's excavation process, the two flushing pumps are activated to increase the flushing of the slurry chamber and cutterhead. When traversing highly plastic and low-permeability strata such as clay, the ball valves of the newly added extension hose 204 are opened or closed as needed to extend the original 9-way central flushing pipe to 13-way, allowing for targeted and enhanced flushing of the cutterhead area. This results in more uniform and effective flushing, preventing the formation of cutterhead mud cake due to insufficient flushing flow. Similarly, to avoid the problem of slag accumulation at the bottom of the excavation chamber, based on the bottom flushing pump of the excavation chamber, a new flushing pipe 501 is installed on the original two bottom flushing connection pipes 502, extending the flushing flow to the bottom flushing pipe 501 of the slurry chamber. The system branches off from the mains and connects to the two gravity-flow slurry pipes 404 and the second inlet slurry pipe 403 that originally led to the bottom of the slurry tank. After opening the pneumatic ball valve, the flushing pump can increase the flushing flow and pressure at the bottom of the slurry tank. The high-pressure slurry output from the flushing pump can enter the turbulence component 602 in the expansion component 6 through the auxiliary pipe 603. It accelerates in the contraction section 6021 and forms a high-speed jet at the throat 6022. Subsequently, the high-pressure fluid is stabilized in the expansion section 6023 and then injected into the bottom flushing pipe 501 and the flushing connecting pipes 502 at both ends of the slurry tank through the expansion connecting pipe 601, achieving a powerful flushing of the dead zone at the bottom of the slurry tank and the inlet area of ​​the gravity-flow slurry pipe. This breaks the static sedimentation state, resuspends the compacted slag, and restores the natural slurry discharge capacity of the gravity-flow slurry pipe. It can switch to continuous high-pressure flushing when there is severe sludge buildup, which ensures dredging efficiency while avoiding excessive flushing that could lead to mud performance degradation or equipment wear. It can greatly improve the smoothness of circulating slag and provide a new way to clear slag buildup in special circumstances. At the same time, it can determine the slag discharge situation at the bottom of the mud chamber by analyzing the real-time pipeline pressure and flushing pump outlet pressure and flow rate. The flushing flow rate at the bottom of the mud chamber can be controlled by adjusting the operating speed of the flushing pump through the tunnel boring machine control room, thereby preventing sludge buildup.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the central flushing component 2, the main slurry feed component 4, the bottom flushing component 5 of the slurry chamber, and the expansion component 6, the problem of mud cake formation at the center of the cutterhead can be solved, making the flushing more uniform and effective. It can also remove the accumulated slag on the cutterhead from multiple directions, improving the flushing efficiency and effect on the cutterhead and slurry chamber. This significantly reduces the possibility of mud cake formation at the center of the cutterhead during tunneling in clay strata, and avoids insufficient slurry chamber flow affecting the slag carrying capacity and causing stagnation during tunneling in clay strata. Regarding the mud cake situation, unnecessary opening and cleaning of mud cake accumulation work is reduced, construction costs are lowered, and tunneling efficiency is improved. By using the expansion hose 204 and expansion component 6, this pipeline can be used as a backup flushing pipeline in special circumstances. When the original pipeline is not smooth for slurry flushing, it can be opened as a backup pipe to ensure the flushing flow rate for normal tunneling. This reduces the workload of opening the chamber, shortens the opening time, reduces equipment wear, and thus significantly reduces equipment maintenance costs, extends equipment service life, and improves equipment stability and reliability.
