Description

Technical Field

[0001] The invention relates to the technical field of anti-floating devices, in particular to an anti-floating device for an underground comprehensive pipe gallery. Background Art

[0002] With the acceleration of urbanization, underground integrated pipe corridors, as an important part of urban infrastructure, undertake the centralized laying of various pipelines such as electricity, communication, water supply, and drainage. However, in areas with high groundwater levels, the buoyancy of groundwater poses a serious threat to the stability of the pipe corridor structure. In order to ensure the safe operation of the pipe corridor, the research and development and application of anti-floating devices are particularly important. At present, there are many anti-floating devices for underground integrated pipe corridors on the market. Most of these devices adopt traditional gravity or pile foundation fixing methods. The gravity anti-floating device mainly resists the buoyancy of groundwater by increasing the weight of the pipe corridor itself, while the pile foundation anti-floating device stabilizes the pipe corridor by connecting the pipe corridor with the pile foundation deep underground and using the bearing capacity of the pile foundation. Although these existing technologies can solve the anti-floating problem of pipeline corridors to a certain extent, there are still some obvious defects: Insufficient stability: Gravity-type anti-floating devices rely too much on the weight of the corridor itself. When the groundwater level fluctuates greatly, it is difficult to ensure the stability and safety of the corridor.

Easy to loosen and poor fixing effect: During long-term use, some anti-floating devices are prone to loosening of fixings due to loose soil or external force, resulting in weakened anti-floating effect or even failure.

DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: the present invention relates to an anti-floating device for an underground integrated pipe gallery, the main purpose of which is to resist the influence of groundwater buoyancy on the pipe gallery structure and ensure the stability and safety of the pipe gallery. The anti-floating device comprises a base 1, sliders 2 are installed on both sides of the top of the base 1 by sliding connection, the top of the slider 2 is connected to a connecting rod 3 by a rotating connection, a fixing ring 4 is arranged between the two connecting rods 3, and the fixing ring 4 is used to fix the pipe gallery. In order to prevent the pipe gallery from floating up under the action of groundwater buoyancy, control components 5 are arranged on both sides of the base 1; The control assembly 5 is composed of a fixed frame 512 fixedly installed on both sides of the bottom of the base 1, and a driving shaft 511 is rotatably connected to the fixed frame 512. A first bevel gear 513 is fixedly connected to the bottom end of the driving shaft 511, and a positioning shaft 514 is rotatably connected to the side wall of the fixed frame 512. A second bevel gear 515 and a second gear 516 are fixedly connected to the positioning shaft 514. The second bevel gear 515 is meshed with the first bevel gear 513 to achieve transmission. The fixed frame 512 is also fixedly connected to a plug-in rod 518 for inserting into the soil for fixing. A compacting block 526 for compacting the soil is slidably connected to the plug-in rod 518. The compacting block 526 is located at the bottom of the fixed frame 512, and a guide rod 527 is fixedly connected to the top thereof. The guide rod 527 is slidably installed on the fixed frame 512. When the driving shaft 511 rotates, it can drive the first bevel gear 513 to rotate synchronously, and then drive the second bevel gear through meshing transmission. 515 rotates, so that the positioning shaft 514 and the second gear 516 rotate synchronously, and the second gear 516 drives the meshing second gear rod 519 and the plug rod 518 to move downward, so as to insert into the soil for positioning and fixing. The plug-in fixation of the plug rod 518 and the soil significantly enhances the stability of the entire pipe gallery structure under the action of groundwater buoyancy. This physical fixing method directly and effectively resists the influence of groundwater buoyancy on the pipe gallery. At the same time, the control component 5 can drive the guide rod 527 and the compaction block 526 to move reciprocatingly downward, so that the compaction block 526 compacts the soil, thereby preventing the plug rod 518 from loosening. Through the plug-in fixation of the plug rod 518 and the soil and the compaction of the soil by the compaction block 526, the anti-floating and anti-sinking device significantly enhances the stability of the entire pipe gallery structure under the action of groundwater buoyancy, and can ensure the stability of the pipe gallery structure even in the case of large water level fluctuations. A ratchet 517 is fixedly connected to the outer end of the positioning shaft 514, a connecting rod 524 is fixedly connected to the outer wall of the fixed frame 512, and a clamping block 523 is rotatably connected. The specifications of the clamping block 523 and the positioning shaft 514 are adapted to each other. A third damping spring 525 is arranged between the connecting rod 524 and the clamping block 523. When the positioning shaft 514 rotates, the ratchet 517 can be driven to rotate synchronously. At the same time, under the elastic force of the third damping spring 525, the clamping block 523 is pushed to move to one side of the ratchet 517. The clamping block 523 can prevent the ratchet 517 from rotating in the opposite direction, thereby ensuring the stable operation of the device. The inner wall of the fixed frame 512 is fixedly connected to a support frame 528, and a connecting shaft 529 is rotatably connected to the support frame 528. One end of the connecting shaft 529 is fixedly connected to the positioning shaft 514, and the other end is fixedly connected to a toggle rod 531. The outer wall of the connecting shaft 529 is sleeved with a movable rod 530, and a protrusion 536 is fixedly connected to the surface of the movable rod 530. The positions of the protrusion 536 and the toggle rod 531 correspond to each other. The other end of the movable rod 530 is rotatably connected to a connecting rod 532, and the bottom of the connecting rod 532 is rotatably connected to a sliding rod 533 slidably installed on the support frame 528. The bottom of the sliding rod 533 is fixedly connected to the compacting block 526, and the outer wall of the sliding rod 533 is fixedly connected to a limiting block 534. A sleeved connecting rod 534 is provided between the limiting block 534 and the support frame 528. The fourth damping spring 535 on 533 can drive the connecting shaft 529 and the toggle rod 531 to rotate synchronously when the positioning shaft 514 rotates. When the toggle rod 531 contacts the protrusion 536, it can drive the movable rod 530 to rotate upward, so that the movable rod 530 drives the sliding rod 533 and the sliding rod 533 to move upward through the connecting rod 532 and compress the fourth damping spring 535. In this way, the sliding rod 533 drives the compacting block 526 to move upward. As the toggle rod 531 rotates, the elastic force of the fourth damping spring 535 can push the limit block 534 and the sliding rod 533 to move downward, thereby driving the compacting block 526 downward, so that the compacting block 526 knocks and compacts the soil, thereby preventing the plug-in rod 518 from loosening. The upper side wall of the plug rod 518 is slidably connected with a second gear rod 519 meshing with the second gear 516, and the bottom of the second gear rod 519 is fixedly connected with a vertical rod 520, and the bottom of the vertical rod 520 is rotatably connected with a push rod 521, and the other end of the push rod 521 is rotatably connected with a cross bar 522, and the cross bar 522 is slidably installed on the plug rod 518. When the second gear rod 519 moves downward, it drives the vertical rod 520 to move downward, so that the vertical rod 520 cooperates with the push rod 521 to drive the cross bar 522 to move horizontally, so that the cross bar 522 is inserted horizontally into the soil, thereby enhancing the stability of the plug rod 518 inserted into the soil; Slide grooves 51 are provided on both sides of the surface of the base 1, and a positioning rod 52 is fixedly connected to the inner wall of the slide groove 51. The slider 2 is slidably installed on the positioning rod 52. The outer side of the slider 2 is provided with a first damping spring 53 sleeved on the positioning rod 52. When the pipe gallery is installed on the fixing ring 4, the fixing ring 4 moves downward under the action of the pipe gallery, and the fixing ring 4 can push the slider 2 to slide on the positioning rod 52 through the connecting rods 3 on both sides, and compress the first damping spring 53. Through the sliding design of the slider 2 on the positioning rod 52 and the compression effect of the first damping spring 53, adaptive adjustment of the pipe gallery after installation is achieved. When the pipe gallery is installed on the fixing ring 4, the fixing ring 4 will automatically adjust its position according to the actual weight and size of the pipe gallery to ensure close contact and stable fixation with the pipe gallery. This adaptive adjustment ability improves the applicability and reliability of the device. The first damping spring 53 provides stable support for the slider 2, and the first damping spring 53 can absorb and disperse these forces, providing effective buffering and shock absorption protection for the pipe gallery, which helps to extend the service life of the pipe gallery and reduce the potential damage risk caused by external forces. Mounting blocks 54 are fixedly connected to both sides of the slider 2, and a ratchet rod 55 is fixedly connected to the other side of the mounting block 54. A positioning block 56 is fixedly connected to the surface of the base 1, and a second damping spring 57 is fixedly connected to one side of the positioning block 56. A clamping rod 58 rotatably mounted on the base 1 is provided at the other end of the second damping spring 57. The clamping rod 58 and the ratchet rod 55 are adapted to each other. When the slider 2 moves to both sides, the mounting blocks 54 and the ratchet rod 55 can be driven to move synchronously. At the same time, under the elastic force of the second damping spring 57, the clamping rod 58 can be pushed to move to one side of the ratchet rod 55, so that the clamping rod 58 can engage with the ratchet rod 55, thereby preventing the slider 2 from moving inward, and the mounting blocks 54, The close combination of the ratchet rod 55, the positioning block 56, the second damping spring 57 and other components, as well as the precise meshing of the first gear rod 59 and the first gear 510, together constitute a stable structure of the device. This design not only improves the anti-floating ability of the device, but also enhances its structural stability and durability when facing various external forces. The bottom of the slider 2 is fixedly connected to the first gear rod 59, and one side of the first gear rod 59 is meshedly connected to the first gear 510 fixedly mounted on the drive shaft 511. When the slider 2 moves to both sides, the slider 2 can drive the first gear rod 59 to move synchronously, so that the first gear rod 59 drives the meshing first gear 510 and the drive shaft 511 to rotate synchronously.

[0017] In the embodiment of the present invention, after the pipe gallery is installed on the fixing ring 4, the fixing ring 4 will move downward under the force of the pipe gallery. At this time, the fixing ring 4 can effectively push the slider 2 to slide along the positioning rod 52 through the connecting rods 3 on both sides, and compress the first damping spring 53 during the sliding process. The sliding design of the slider 2 on the positioning rod 52 and the compression effect of the first damping spring 53 ensure that the slider 2 can drive the mounting block 54 and the ratchet rod 55 to move synchronously when moving to both sides. At the same time, under the elastic force of the second damping spring 57, the clamping rod 58 will be pushed to move to one side of the ratchet rod 55, so that the clamping rod 58 can be engaged with the ratchet rod 55 to prevent the slider 2 from moving inward. The mounting block 54, the ratchet rod 55, the positioning block 56 and the second damping spring 57 are tightly combined, and the first gear rod 57 is The precise meshing of 59 and the first gear 510 together constitutes a stable structure of the device. This design not only improves the anti-floating ability of the device, but also enhances its structural stability and durability when facing various external forces. The bottom of the slider 2 is fixedly connected with a first gear rod 59, and one side of the first gear rod 59 is meshedly connected with a first gear 510 fixedly installed on the drive shaft 511. When the slider 2 moves to both sides, the slider 2 can drive the first gear rod 59 to move synchronously, so that the first gear rod 59 drives the meshed first gear 510 and the drive shaft 511 to rotate synchronously. When the positioning shaft 514 rotates, it can drive the ratchet 517 to rotate synchronously. At the same time, under the elastic force of the third damping spring 525, the block 523 is pushed to move to one side of the ratchet 517. The ratchet 517 can be prevented from rotating in the opposite direction by setting the block 523. When the driving shaft 511 rotates, it can drive the first bevel gear 513 to rotate synchronously, and the first bevel gear 513 drives the meshing second bevel gear 515 to rotate, so that the second bevel gear 515 drives the positioning shaft 514 and the second gear 516 to rotate synchronously, and the second gear 516 drives the meshing second gear rod 519 and the plug rod 518 to move downward, so that the plug rod 518 is inserted into the soil for positioning and fixing. The plug-in fixation of the plug rod 518 and the soil significantly enhances the stability of the entire pipe gallery structure under the buoyancy of groundwater This physical fixing method directly and effectively resists the influence of groundwater buoyancy on the pipe gallery. At the same time, it can drive the guide rod 527 and the compaction block 526 to move reciprocatingly downward, so that the compaction block 526 compacts the soil, thereby preventing the plug-in rod 518 from loosening. Through the plug-in fixation of the plug-in rod 518 and the soil and the compaction of the soil by the compaction block 526, the anti-floating and anti-sinking device significantly enhances the stability of the entire pipe gallery structure under the action of groundwater buoyancy, and can ensure the stability of the pipe gallery structure even when the water level fluctuates greatly. When the positioning shaft 514 rotates, it can drive the connecting shaft 529 and the toggle rod 531 to rotate synchronously. When the toggle rod 531 contacts the protrusion 536, it can drive the movable rod 530 to rotate upward, so that the movable rod 530 drives the sliding rod 533 and the sliding rod 533 to move upward through the connecting rod 532, and compresses the fourth damping spring 535, so that the sliding rod 533 drives the compacting block 526 to move upward. With the rotation of the toggle rod 531, under the elastic force of the fourth damping spring 535, the limit block 534 and the sliding rod 533 can be pushed downward, thereby driving the compacting block 526 downward, so that the compacting block 526 knocks and compacts the soil, thereby preventing the plug-in rod 518 from loosening; During the downward movement of the second gear rod 519, the vertical rod 520 will be driven to move downward. The vertical rod 520 cooperates with the push rod 521 to drive the cross rod 522 to move horizontally, so that the cross rod 522 is inserted horizontally into the soil, thereby enhancing the stability of the plug-in rod 518 inserted into the soil. This horizontal insertion design further improves the stability of the entire corridor structure under the action of groundwater buoyancy, ensures the stability of the plug-in rod 518, and effectively prevents the displacement of the corridor structure due to groundwater buoyancy.
