Description

Technical Field

[0001] This invention belongs to the field of slag and soil treatment technology, specifically relating to a shield tunnel slag and soil treatment equipment and process. Background Technology

[0002] Shield tunneling excavation waste consists of waste soil and rock fragments generated during the construction of tunnel boring machines (TBMs). Its treatment is crucial for environmental protection and construction safety. Shield excavation waste mainly consists of soil, rock fragments, cement, and sand, containing high water content and impurities. Because TBM construction requires traversing underground, the waste typically exhibits high viscosity and instability, while also containing certain organic matter and heavy metals. Improper treatment can lead to toxic substances in the waste polluting soil and water bodies, affecting plant growth and human health. Furthermore, sand particles may clog rivers and lakes, impacting aquatic ecosystems. The treatment of shield excavation waste is a comprehensive process aimed at minimizing environmental impact and achieving rational resource utilization. The main steps and methods for shield excavation waste treatment are as follows: First, the waste is classified, separating particles of different sizes, recyclable materials such as metals and plastics, and hazardous substances such as chemical pollutants. Screening equipment is used to sieve the waste, removing large rocks and stones for subsequent processing. Shield excavation waste typically contains high moisture content and requires dehydration treatment. This can be achieved through mechanical dewatering methods such as centrifuges and filter presses, or natural drying. Dewatered soil is easier to handle and transport, while reducing the risk of pollution during transportation.

[0003] In the existing technology, shield tunneling excavated soil has a high viscosity and tends to clump together during the treatment process. Because shield tunneling excavated soil passes underground, it has a high viscosity and may clump together and become impossible to separate during the treatment process, resulting in incomplete screening. Furthermore, the large clumps of soil that clump together will also affect the screening effect. In addition, the highly viscous soil will also adhere to the screen holes, causing screen blockage and affecting screening efficiency. Summary of the Invention

[0009] In some publicly available images, a discharge device is installed at one end of the support frame, and three partitions are installed on the inner wall of the discharge device. The bottom of the discharge device is equipped with a first discharge port, a second discharge port, and a third discharge port.

The inner wall of the fixing frames is equipped with multiple reinforcing ribs. A screening screen is laid on top of the fixing frames, and the aperture of the screening screen decreases from top to bottom. The three screening screens are respectively connected to three partitions.

[0012] In some publicly available images, a removable maintenance plate is bolted to the top of the storage tank, a water spray pipe is installed through the front of the storage tank, a first gear is installed on the outer wall of the water spray pipe, a connecting pipe is installed at one end of the water spray pipe, and a water pump is installed on the inner top wall of the storage tank.

[0013] In some disclosures, a motor is installed on one inner wall of the storage box, and a second gear is installed at the output end of the motor. The second gear is a half-tooth gear and meshes with the first gear. Two driven gears are installed on one inner wall of the storage box, one of which meshes with the second gear. Two reversing gears are installed between the two driven gears and mesh with the two driven gears respectively. A third gear is installed on the inner wall of the storage box and meshes with the driven gear and the first gear.

[0014] In some publicly available descriptions, the storage box has multiple second frames installed on its inner bottom wall, a second shaft installed on the outer wall of the second frame, a second torsion spring installed on the outer wall of the second shaft, a trigger rod installed on the outer wall of the second shaft, and the bottom of the trigger rod extends out of the bottom of the storage box.

[0016] A process for treating tunnel boring machine (TBM) excavation soil includes the following steps:

[0017] S1. First, dump the tunnel boring machine's excavated soil into this device;

[0018] S2. The water spray pipe that can rotate left and right is used to initially impact the clumps of slag, so that the clumps of slag can be partially broken up.

[0019] S3. The clumps of slag impact the trigger rod, which in turn drives the spray head to spray high-pressure water, which impacts the clumps of slag a second time, causing the slag to break up again. The water impact of the two water jets increases the moisture content of the slag and improves its fluidity.

[0020] S4. Finally, the unbroken slag is crushed by the roller. The roller presses down on the slag, forcing the clumps of slag to break up, thus completing the screening and preventing the screen from clogging.

[0021] In some publicly available descriptions, a jet pipe is installed through the bottom of the storage tank, multiple jet heads are installed at the bottom of the jet pipe, a valve is installed on the outer wall of the jet pipe, a baffle plate is installed inside the valve, a third spring is installed on the inner bottom wall of the valve, a sealing plate is installed on the top of the third spring, and guide wheels are installed on both the inner bottom wall and the outer wall of the valve. The sealing plate, guide wheels, guide wheels and moving ring are connected by cables.

[0022] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0023] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0024] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0025] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0026] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention uses a compaction structure to crush clumps of slag, thereby preventing clogging of the screen. During rotation, the eccentric wheel contacts the impact plate, causing the impact plate to rotate. One end of the impact plate rises while the other end falls. The first torsion spring returns the impact plate to its initial position, thereby pressing the lifting rod down. The falling of the lifting rod causes the first spring to contract, and then the lifting rod drives the compaction plate down. The compaction plate crushes the clumps of slag on the screening screen, breaking up the clumps and facilitating screening.

[0029] 2. This invention uses a trigger rod and a spray head to impact and break up clumps of slag. During the movement of the moving ring, the cable is pulled, and the cable pulls the sealing plate downward through the guide wheel and the guide wheel. The sealing plate separates from the blocking plate, allowing water to flow through. The spray pipe is connected to the output end of the water pump. Thus, when the clumps of slag pass through the spray head, the high-pressure water jet from the spray head impacts the clumps of slag, breaking them up and facilitating screening.

[0030] 3. This invention can increase the moisture content of the slag, thereby reducing its stickiness and preventing it from sticking to the screen. The water flow impact not only breaks up the slag lumps but also increases the moisture content of the slag. The increased moisture content improves the fluidity of the slag, preventing it from sticking to the screen and effectively preventing the screen from clogging. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 8 and Figure 9A shield tunneling excavation waste treatment device includes a support frame 1 and a storage box 5. A screening shell 3 is installed above the support frame 1, and the storage box 5 is installed above the screening shell 3. Two sets of No. 1 frames 9 are installed on the inner wall of the storage box 5. A No. 1 shaft 91 is installed on the outer wall of the No. 1 frame 9. An impact plate 92 is installed on the outer wall of the No. 1 shaft 91, and one end of the impact plate 92 extends out of the outer wall of the storage box 5. A first torsion spring 93 is installed on the outer wall of the No. 1 shaft 91. A lifting rod 94 is installed through the inner bottom wall of the storage box 5. A first spring 95 is installed around the outer wall of the lifting rod 94. A rolling plate 96 is installed at the bottom of the lifting rod 94, and the rolling plate 96 is tilted upward at a certain angle.

[0047] Specifically, during screening, the portion of the impact plate 92 located outside the storage box 5 is positioned above the eccentric wheel 33. As the eccentric wheel 33 rotates, it comes into contact with the impact plate 92, causing the impact plate 92 to rotate. One end of the impact plate 92 tilts up, while the other end descends. The first torsion spring 93 can then drive the impact plate 92 back to its initial position, thereby pressing the lifting rod 94 down. The descent of the lifting rod 94 causes the first spring 95 to contract. Subsequently, the lifting rod 94 drives the rolling plate 96 down, which then rolls the shield tunneling slag adhering to the screening mesh 42, causing the adhering slag to break up and thus facilitating screening.

[0048] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A ladder 11 is installed on the outer wall of the support frame 1, a guardrail 12 is installed on the top of the support frame 1, multiple support columns 14 are installed on the bottom of the support frame 1, a buffer 13 is installed on the top of the support frame 1, a discharge device 2 is installed at one end of the support frame 1, three partitions 21 are installed on the inner wall of the discharge device 2, and a first discharge port 22, a second discharge port 23, and a third discharge port 24 are respectively installed at the bottom of the discharge device 2. The outer wall of the screening shell 3 is connected to the buffer 13, and a drive shaft 31 is installed through the outer wall of the screening shell 3. A pulley 32 is installed at one end of the drive shaft 31. An eccentric wheel 33 is installed on the outer wall of the screening shell 3. A feed plate 34 is installed at one end of the screening shell 3. A drive motor 35 is installed on the top of the support frame 1. The output end of the drive motor 35 is connected to the drive shaft 31 through a pulley 32 and a belt drive. A fourth discharge port 36 is installed at the bottom of the screening shell 3. Three sets of fixed frames 4 are installed on the inner wall of the screening shell 3 from top to bottom. Multiple reinforcing ribs 41 are installed on the inner wall of the fixed frame 4. A screening screen 42 is laid on the top of the fixed frame 4. The aperture of the screening screen 42 decreases from top to bottom. The three screening screens 42 are respectively connected to three partitions 21.

[0049] Specifically, the ladder 11 and guardrail 12 facilitate staff to view and maintain the equipment, the support column 14 supports the support frame 1, and the shield tunneling excavated soil is poured from the feed plate 34 onto the screening screen 42. The screening screen 42 screens the excavated soil. Due to the presence of three screening screens 42, the screened excavated soil can be screened from coarse to fine. Secondly, the mud in the excavated soil will be discharged through the fourth discharge port 36, and the other excavated soil will be discharged from the first discharge port 22, the second discharge port 23 and the third discharge port 24 respectively. According to the different coarseness of the excavated soil discharged from the first discharge port 22, the second discharge port 23 and the third discharge port 24, the fine excavated soil is pressed into mud cake by a filter press for backfilling the pit, and the other excavated soil can be sintered according to actual needs to make it into bricks and reused in the project.

[0050] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A removable maintenance plate 51 is bolted to the top of the storage tank 5. A water spray pipe 52 is installed through the front of the storage tank 5. A first gear 53 is installed on the outer wall of the water spray pipe 52. A connecting pipe 54 is installed at one end of the water spray pipe 52. A water pump 55 is installed on the inner top wall of the storage tank 5. A motor 6 is installed on one side inner wall of the storage tank 5. A second gear 61 is installed at the output end of the motor 6. The second gear 61 is a half-tooth gear and meshes with the first gear 53. Two driven gears 62 are installed on one side inner wall of the storage tank 5. One of the driven gears 62 meshes with the second gear 61. Two reversing gears 63 are installed between the two driven gears 62. The two reversing gears 63 mesh with the two driven gears 62 respectively. A third gear 64 is installed on the inner wall of the storage tank 5. The third gear 64 meshes with the driven gear 62 and the first gear 53.

[0051] Specifically, when the clump of slag moves to the bottom of the storage box 5, the motor 6 rotates, driving the second gear 61 to rotate. The second gear 61 rotates, driving the driven gear 62 to rotate. The driven gear 62 drives the reversing gear 63 to rotate. The reversing gear 63 drives the third gear 64 to rotate, thereby enabling the water spray pipe 52 to spray left and right. The output end of the water pump 55 is connected to the water spray pipe 52, and the water pump 55 is a high-pressure water pump. The water spray pipe 52 swings left and right to perform a preliminary impact on the clump of slag, so as to facilitate subsequent crushing.

[0052] Please see Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12The storage box 5 has multiple secondary frames 7 installed on its inner bottom wall. A secondary shaft 71 is installed on the outer wall of the secondary frame 7. A second torsion spring 73 is installed on the outer wall of the secondary shaft 71. A trigger rod 72 is installed on the outer wall of the secondary shaft 71, with its bottom extending beyond the bottom of the storage box 5. A protective shell 8 is installed on the inner wall of the storage box 5. A horizontal shaft 81 is installed on the inner wall of the protective shell 8. Two fixing plates 82 are installed on the outer wall of the horizontal shaft 81. A return spring 83 is fitted onto the outer wall of the horizontal shaft 81. A moving ring 84 is fitted onto the outer wall of the horizontal shaft 81. Multiple L-shaped fixing strips 85, made of rubber, are installed on the inner wall of the moving ring 84. The bottom of the moving ring 84... A vertical rod 86 is installed on the part, and the vertical rod 86 extends out of the bottom of the protective shell 8. Multiple guide wheels 87 are installed on the inner wall of the protective shell 8. A spray pipe 10 is installed through the bottom of the storage box 5. Multiple spray heads 102 are installed at the bottom of the spray pipe 10. A valve 101 is installed on the outer wall of the spray pipe 10. A baffle plate 103 is installed inside the valve 101. A third spring 104 is installed on the inner bottom wall of the valve 101. A sealing plate 105 is installed on the top of the third spring 104. Guide wheels 106 are installed on both the inner bottom wall and the outer wall of the valve 101. The sealing plate 105, guide wheels 106, guide wheels 87 and moving ring 84 are connected by cables.

[0053] Specifically, when the adhering slag hits the trigger rod 72, the top of the trigger rod 72 presses against the vertical rod 86. The vertical rod 86 moves, causing the moving ring 84 to slide on the horizontal axis 81. At this time, the moving ring 84 will press against the return spring 83. The return spring 83 is in a compressed and energy-storing state. At the same time, during the movement of the moving ring 84 on the horizontal axis 81, the fixing strip 85 contacts the horizontal axis 81. During the movement, the moving ring 84 pulls the cable. The cable passes through the guide wheel 87 and the guide wheel 106, which pulls the sealing plate 105 downward. The sealing plate 105 separates from the blocking plate 103, allowing water to flow through. The spray pipe 10 is connected to the output end of the water pump 55. Thus, when the adhering slag passes through the spray head 102, the high-pressure water jet from the spray head 102 impacts the adhering slag and breaks it up, making it easier to screen.

[0054] During the above process, when the slag block no longer presses against the trigger rod 72, the return spring 83 begins to extend and pushes the moving ring 84 to move back to the initial position. During the reverse movement of the moving ring 84, the fixing bar 85 will change in the vertical direction due to the frictional force caused by the bottom end contacting the horizontal axis 81. At this time, the frictional force between the fixing bar 85 and the horizontal axis 81 is large, and the return spring 83 will slowly push the moving ring 84 back to its original position. Thus, when the adhered slag block passes the trigger rod 72, the valve 101 remains open and can continue to impact the slag block.

[0055] The above method not only breaks up the slag lumps, but also increases the moisture content of the slag. The increased moisture content improves the fluidity of the slag, preventing it from sticking to the screening screen 42 and effectively preventing clogging of the screening screen 42.

[0056] Working principle: The tunnel boring machine excavated soil is poured from the feed plate 34 onto the screening screen 42. The screening screen 42 screens the soil. When the adhering soil moves to the bottom of the storage box 5, the motor 6 rotates, driving the second gear 61 to rotate. The second gear 61 rotates, driving the driven gear 62 to rotate. The driven gear 62 rotates, driving the reversing gear 63 to rotate. The reversing gear 63 rotates, driving the third gear 64 to rotate. This allows the water spray pipe 52 to spray left and right. The output end of the water pump 55 is connected to the water spray pipe 52, and the water pump... 55 is a high-pressure water pump. The water spray pipe 52 oscillates left and right to initially impact the adhered slag, facilitating further crushing. When the adhered slag impacts the trigger rod 72, the top of the trigger rod 72 presses against the vertical rod 86. The vertical rod 86 moves, causing the moving ring 84 to slide on the horizontal shaft 81. At this time, the moving ring 84 compresses the return spring 83, putting the return spring 83 into a compressed, energy-storing state. Simultaneously, as the moving ring 84 moves on the horizontal shaft 81, the fixing strip 85 contacts the horizontal shaft 81. During the movement, 84 pulls the cable, which, via guide wheel 87 and guide wheel 106, pulls the sealing plate 105 downwards. The sealing plate 105 separates from the blocking plate 103, allowing water to flow through. The jet pipe 10 is connected to the output end of the water pump 55, so that when the adhered soil blocks pass through the jet head 102, the high-pressure water jet from the jet head impacts and breaks up the adhered soil blocks, facilitating screening. The impact plate 92, located outside the storage box 5, is positioned above the eccentric wheel 33. During rotation, wheel 33 comes into contact with impact plate 92, causing impact plate 92 to rotate. One end of impact plate 92 tilts up and the other end drops. The first torsion spring 93 can drive impact plate 92 back to its initial position, thereby squeezing lifting rod 94 down. The drop of lifting rod 94 causes the first spring 95 to contract. Then, lifting rod 94 drives rolling plate 96 down. Rolling plate 96 rolls the shield tunneling slag adhering to the screening screen 42, so that the adhering slag can be broken up, thus facilitating screening.

7. A process for treating tunnel boring machine (TBM) spoil is applicable to the TBM spoil treatment equipment described in any one of claims 1-6, characterized in that, The processing steps are as follows: S1. First, dump the tunnel boring machine's excavated soil into this device; S2. The clumps of slag are initially impacted by a water spray pipe (52) that can rotate left and right, so that the clumps of slag can be broken up first. S3. The clumps of slag impact the trigger rod (72), thereby driving the spray head (102) to spray high-pressure water, which impacts the clumps of slag a second time, causing the slag to break up again. The water content of the slag is increased by the two water impacts, and the fluidity of the slag is also improved. S4. Finally, the unbroken slag is crushed by the roller (96). The roller (96) presses the slag downward to force the clumps of slag to break up, thereby completing the screening and preventing the screen from clogging.
