Description

Technical Field

[0001] The present application relates to the technical field of filling pores after steel sheet piles are pulled out in underground pipe gallery projects, and in particular to a device for filling pores after steel sheet piles are pulled out in underground pipe gallery projects. Background Art

[0002] An underground pipeline gallery project is a project used to lay various pipelines (such as electricity, communications, water supply, drainage, natural gas, etc.) and other facilities to protect them from the impact of the external environment and ensure the normal operation and maintenance of urban infrastructure. It has the advantages of pipeline protection, urban beautification, space saving and convenient maintenance.

[0003] During the construction of underground pipeline corridor projects, tunnels need to be excavated on the ground. After the tunnels are excavated, construction treatment needs to be carried out inside the tunnels. In order to avoid problems such as earth collapse in the tunnels after excavation, steel sheet piles are often used to support the tunnel excavation to ensure safety during the construction process.

[0004] When the tunnel construction is completed, the required pipelines are buried inside the tunnel and the tunnel is backfilled and compacted. Finally, the steel sheet piles are taken out. Since the steel sheet piles will leave pores on the ground after being taken out, in order to ensure the stability of the foundation and reduce structural damage, it is often necessary to backfill the pores after the steel sheet piles are taken out.

[0005] For example, the patent application with publication number CN220813892U discloses a Larsen steel sheet pile hole backfilling device, including a base plate and a vertical plate, the vertical plate is fixedly connected to the upper end surface of the base plate, a material box is fixedly connected to the side wall of the vertical plate, a connecting hole is opened in the base plate, a first material discharge pipe is installed in the connecting hole, a second material discharge pipe is slidably connected to the side wall of the first material discharge pipe, a mounting plate is fixedly connected to the side wall of the material box, a servo motor is fixedly installed on the upper end surface of the mounting plate, the output end of the servo motor passes through the mounting plate and is fixedly connected to a threaded rod, the servo motor is started, the telescopic end of the servo motor drives the threaded rod to rotate, the threaded rod drives the lower pressing block to move downward through the threaded block and the vertical rod, the lower pressing block can press the filling material downward, so that the filling material can enter the pile hole more quickly, and at the same time, the filling material can be tighter, thereby increasing the firmness.

[0006] After the tunnel is backfilled with soil, even if the backfilled soil is compacted, there is still a hardness difference between the soil on both sides of the steel sheet piles, that is, the hardness of the soil on the original unexcavated ground is greater than the soil backfilled inside the tunnel. Therefore, the above-mentioned prior art still has some defects when backfilling the steel sheet pile holes: due to problems such as soil moisture, the soil backfilled in the tunnel may collapse toward one side of the pile hole due to the weight of the above-mentioned backfilling device and the trampling of construction workers, thereby causing the upper side of the pile hole to close so that the first feed pipe and the second feed pipe cannot smoothly enter the pile hole. Therefore, when the subsequent backfilling device fills the filling material into the pile hole, the pile hole needs to be manually opened before the filling material can be filled into the pile hole. Even if the pile hole can be opened without manual labor, the thickness of the filler on the lower side of the pile hole is greater than the thickness on the upper side of the pile hole, resulting in uneven distribution of the filler on the vertical plane inside the pile hole, affecting the efficiency and quality of pile hole backfill.

[0007] Since the steel sheet pile has a certain length, and the first and second feed pipes are stationary when filling the filler into the pile hole, the filler accumulates at a certain place inside the pile hole during filling. Although the filler is squeezed by the pressing block, it may not be evenly distributed in the horizontal plane, affecting the backfill effect of the pile hole.

[0008] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for backfilling steel sheet pile holes. Summary of the invention

DETAILED DESCRIPTION

[0063] The following is combined with Figures 1 to 9 This application is described in further detail.

[0064] The embodiment of the present application discloses a device for filling pores after steel sheet piles are pulled out in an underground pipe gallery project, which can remove the backfill soil covering the upper side of the pores to facilitate the subsequent backfilling of the pores with filling materials.

[0065] Embodiment 1:

[0066] See also Figure 1 A pore filling device for pulling out steel sheet piles in an underground pipe gallery project comprises a moving trolley 1, on which a toggle plate 2, a telescopic tube 3 and a stamping block 4 are installed.

[0067] The toggle plate 2 is an inverted L-shaped structure and is installed under the moving trolley 1 to remove the backfill soil covering the pores. A toggle mechanism 100 is provided between the toggle plate 2 and the moving trolley 1 to drive the toggle plate 2 to remove the backfill soil.

[0068] The telescopic tube 3 is installed above the moving trolley 1 and reciprocates along the length direction of the moving trolley 1 to pour fillers into the pores. A telescopic mechanism 20 is installed between the telescopic tube 3 and the moving trolley 1.

[0069] The punching block 4 is installed through the moving trolley 1 and is used for punching the filler. The punching block 4 is provided with a through groove matched with the telescopic tube 3 .

[0070] During specific work, the mobile trolley 1 is pushed to move the toggle plate 2 to be directly above the hole, and the mobile trolley 1 is limited and fixed by the existing braking device on the mobile trolley 1, so that the mobile trolley 1 is fixed on the ground, thereby reducing the possibility of shaking of the mobile trolley 1 during subsequent construction and improving the stability of the equipment.

[0071] Then, the two ends of the hole are sealed with existing rectangular plates.

[0072] The toggle plate 2 is driven to be inserted into the pore. After the toggle plate 2 is inserted into the pore, the toggle plate 2 is pushed to move to drive the backfill soil to move, so that the backfill soil covering the top of the pore is removed. At this time, the pore is open, avoiding the tediousness of manual digging, and facilitating the subsequent filling material to smoothly enter the pore. At the same time, the upper and lower widths of the pore after opening are consistent, thereby ensuring the uniformity of the vertical distribution of the filling material inside the pore.

[0073] The telescopic tube 3 that can reciprocate along the moving trolley 1 can spread the filler into the pores, thereby reducing the possibility of uneven distribution of the filler due to accumulation of the filler at a certain point in the pores.

[0074] After the punching block 4 spreads a certain thickness of filler inside the pore, it punches the filler so that the filler is evenly spread inside the pore. At the same time, the punching block 4 can compact the filler when pressing down to ensure that the filler fully supports the pore.

[0075] See also Figure 2 The toggle mechanism 100 includes a linkage plate 11, a vertical rod 12, a driving cylinder 13, a rotating motor 14 and a threaded rod 15.

[0076] The linkage plates 11 are symmetrically mounted on the toggle plates 2 along the length direction of the moving trolley 1 to drive the toggle plates 2 to move along the height direction of the moving trolley 1 .

[0077] The vertical rod 12 is slidably disposed on the moving trolley 1 , and the vertical rod 12 slidably penetrates the linkage plate 11 , and is used to cooperate with the linkage plate 11 to drive the toggle plate 2 to move along the width direction of the moving trolley 1 .

[0078] The driving cylinder 13 is installed on the vertical rod 12 through a cylinder seat, and the telescopic end of the driving cylinder 13 is connected to the linkage plate 11.

[0079] The rotating motor 14 is mounted on the moving vehicle 1 through a motor seat.

[0080] The threaded rod 15 is mounted on the output shaft of the rotating motor 14 , and one end of the threaded rod 15 away from the rotating motor 14 is penetrated and mounted on the vertical rod 12 by means of a threaded connection.

[0081] During specific operation, after the moving trolley 1 is fixed and limited, the driving cylinder 13 is started. During the movement of the telescopic end of the driving cylinder 13, the linkage plate 11 is driven to move toward the gap. During the movement of the linkage plate 11, the toggle plate 2 is driven to be inserted into the gap. When the toggle plate 2 enters the gap, the driving cylinder 13 is closed, and the rotating motor 14 is started at this time. During the rotation of the output shaft of the rotating motor 14, the threaded rod 15 is driven to rotate. During the rotation of the threaded rod 15, the vertical rod 12 is driven to move along the width direction of the moving trolley 1. During the movement of the vertical rod 12, the toggle plate 2 is driven to move through the linkage frame 115. During the movement of the toggle plate 2, the backfill soil covering the top of the gap can be removed, thereby opening the gap.

[0082] See also Figure 3 The telescopic mechanism 20 includes a profile frame 16, a counterweight block 17 and a traction rope 18.

[0083] The profile frame 16 is slidably arranged on the moving trolley 1 , and the telescopic tube 3 is penetrated and arranged on the horizontal section of the profile frame 16 .

[0084] The counterweight block 17 is installed at one end of the telescopic tube 3 away from the profile frame 16, driving the telescopic tube 3 to extend.

[0085] The traction rope 18 is arranged inside the telescopic tube 3 and installed at one end of the telescopic tube 3 away from the molded frame 16.

[0086] During specific work, after the backfill soil covering the top of the pore is removed, the traction rope 18 is released, that is, the end of the telescopic tube 3 with the counterweight 17 is not subject to tension. At this time, the counterweight 17 drives the telescopic tube 3 to extend, and the telescopic end of the telescopic tube 3 moves toward the inside of the pore. When the telescopic end of the telescopic tube 3 moves to the specified position, filler is poured into the telescopic tube 3, and the filler falls to the bottom of the pore through the telescopic tube 3. At this time, the external driving force (cylinder, etc.) drives the profile frame 16 to reciprocate in the length direction of the mobile trolley 1, and the profile frame 16 drives the telescopic tube 3 to reciprocate during the movement. During the reciprocating movement of the telescopic tube 3, the filler can be spread into the inside of the pore, so that the filler can be evenly spread inside the pore, ensuring the uniformity of the horizontal distribution of the filler inside the pore.

[0087] See also Figure 1 , Figure 3 as well as Figure 4Since the gap is wider than the width of the telescopic tube 3, in order to ensure that the filler can be evenly distributed inside the gap, the present invention also provides a connecting pipe 31 to ensure that the filler is evenly distributed inside the gap. Specifically, the telescopic tube 3 is equipped with a connecting pipe 31 and a gear 32, and the mobile car 1 is equipped with a fixed frame 19 and a rack plate 10.

[0088] The connecting pipe 31 is installed at one end of the telescopic pipe 3 away from the moving vehicle 1 , and the connecting pipe 31 is connected to the telescopic pipe 3 .

[0089] The gear 32 is mounted on one end of the telescopic tube 3 close to the moving trolley 1 .

[0090] The fixed frame 19 is installed on the mobile vehicle 1.

[0091] The rack plate 10 is mounted on the fixed frame 19 and meshes with the gear 32 .

[0092] The telescopic end of the telescopic tube 3 extends out of the stamping block 4 through the through groove, so the connecting tube 31 is also located outside the stamping block 4 when in the starting position, and is perpendicular to the through groove. The connecting tube 31 is a through structure, and a leakage port is provided on the side of the connecting tube 31 away from the telescopic tube 3, and the diameter of the section of the telescopic tube 3 close to the connecting tube 31 is larger than the diameter of the leakage port, to ensure that the filler falling into the connecting tube 31 by the telescopic tube 3 will not directly leak out from the leakage port, and to ensure that the filler falls out from both ends of the connecting tube 31. During specific operation, the filler inside the telescopic tube 3 falls through the connecting tube 31 to the two ends of the connecting tube 31 and the leakage port, so that the filler can be evenly distributed inside the gap, further improving the uniformity of the filling in the gap.

[0093] When the filler is spread to a certain thickness inside the gap, the mold frame 16 drives the telescopic tube 3 to move to the rack plate 10. During the movement of the telescopic tube 3, the gear 32 cooperates with the rack plate 10 to rotate 90 degrees. At this time, the connecting tube 31 coincides with the through groove, avoiding the collision of the stamping block 4 with the connecting tube 31 during stamping in the subsequent process, causing damage to the connecting tube 31.

[0094] See also Figure 5 A support frame 111, a rotating shaft 112 and a connecting rope 113 are installed on the moving vehicle 1.

[0095] The two support frames 111 are symmetrically installed on the moving trolley 1 along the length direction of the moving trolley 1 , and a lifting mechanism 30 is installed on the support frames 111 and the moving trolley 1 .

[0096] The rotating shaft 112 is rotatably installed between the two supporting frames 111 via a bearing.

[0097] The connecting rope 113 corresponds to the supporting frame 111 one by one. One end of the connecting rope 113 is installed on the punching block 4 , and the other end of the connecting rope 113 away from the punching block 4 is wound around the rotating shaft 112 .

[0098] A linkage ring 114 and a linkage frame 115 are mounted on the rotating shaft 112 .

[0099] The linkage ring 114 is slidably disposed on the rotating shaft 112 in a limited manner, and one end of the traction rope 18 away from the telescopic tube 3 is wound around the linkage ring 114 .

[0100] The linkage frame 115 has one end mounted on the horizontal section of the shaped frame 16 and the other end mounted on the linkage ring 114 through a bearing. The linkage frame 115 is sleeved on the rotating shaft 112. When the rotating shaft 112 rotates, the linkage frame 115 will not be driven to rotate, and the linkage frame 115 slides along the axial direction of the rotating shaft 112.

[0101] At the starting position, the connecting rope 113 is in a winding state. During specific operation, when it is necessary to fill the gap with filler, the rotating shaft 112 is reversed by an external driving force (motor, etc.). During the reversal of the rotating shaft 112, the connecting rope 113 is released. At this time, the stamping block 4 moves toward the inside of the gap. During the movement of the stamping block 4, the rotating shaft 112 synchronously drives the traction rope 18 to be released through the linkage ring 114. At this time, the telescopic tube 3 is synchronously extended toward the inside of the gap due to the drive of the counterweight block 17. When the telescopic tube 3 reciprocates along the length direction of the moving trolley 1, the mold frame 16 drives the linkage ring 114 to slide synchronously on the rotating shaft 112 through the linkage frame 115. During the rotation of the rotating shaft 112, the linkage ring 114 is driven to rotate. Then, during the rotation of the rotating shaft 112, the linkage ring 114, the connecting rope 113 and the traction rope 18 cooperate with each other to make the stamping block 4 and the telescopic tube 3 move synchronously toward the inside of the gap, thereby reducing the tediousness of placing them one by one.

[0102] Continue reading Figure 5 The lifting mechanism 30 includes a rotating shaft 116, a vertical frame 117, a linkage shaft 118 and a transition shaft 119.

[0103] There are two rotating shafts 116 , which are respectively mounted on the corresponding support frames 111 through bearings. A round hole for the connecting rope 113 to pass through is opened on the rotating shafts 116 .

[0104] The vertical frame 117 corresponds to the rotating shaft 116 one by one, is slidably arranged on the moving trolley 1, and is automatically reset by a reset spring rod arranged on the moving trolley 1.

[0105] The linkage shaft 118 is installed on the vertical frame 117 through a bearing. The end of the connecting rope 113 away from the punching block 4 passes through the circular holes in sequence, bypasses the linkage shaft 118, and is then wound around the rotating shaft 112.

[0106] The transition shaft 119 is mounted on the two support frames 111 via bearings.

[0107] The two ends of the transition shaft 119 are respectively connected to the rotating connecting shaft 116 on the same side through a belt transmission method. Since the belt transmission method is a prior art, it will not be repeated here and the belts and pulleys required for the belt transmission are not shown in the figure. The mobile trolley 1 is equipped with fixed protrusions corresponding to the vertical frame 117 one by one, and a reset spring rod is installed between the fixed protrusion and the corresponding vertical frame 117 for resetting the vertical frame 117. During specific operation, when the filler is spread to a certain thickness inside the gap, the transition shaft 119 is driven to rotate by the existing motor. During the rotation of the transition shaft 119, the rotating connecting shaft 116 is driven to rotate a certain number of times through the belt transmission method. During the rotation of the rotating connecting shaft 116, when the connecting rope 113 is wound around, the connecting rope 113 drives the stamping block 4 to lift upward for a certain distance. At this time, the connecting rope 113 drives the vertical frame 117 to move to one side of the stamping block 4 through the linkage shaft 118, and the reset spring rod is stretched.

[0108] At this time, the transition shaft 119 is released, and the transition shaft 119 rotates without any restraint. During the rotation of the transition shaft 119, the rotating connecting shaft 116 is driven to rotate through the belt transmission. At this time, the connecting rope 113 is no longer constrained, and the reset spring rod resets and drives the vertical frame 117 to reset. The punching block 4 moves downward due to gravity, and the punching block 4 can pass through the connecting pipe 31 to punch the flat filler, wherein the reset spring rod and the vertical frame 117 cooperate with each other to compensate for the displacement of the punching block 4 passing through the connecting pipe 31 and contacting the filler, thereby avoiding the punching block 4 being unable to pass through the connecting pipe 31 and affecting the punching effect of the punching block 4.

[0109] After that, the above-mentioned action is repeated every time a filler of a certain thickness is laid, and the laid filler can be punched.

[0110] See also Figure 6 A rotating shaft 33 is installed inside a section of the telescopic tube 3 away from the molded frame 16 through a bearing, and a spiral blade 34 is installed on the rotating shaft 33.

[0111] During specific operation, the rotating shaft 33 is driven to rotate by an existing external driving force (motor, etc.). During the rotation of the rotating shaft 33, the spiral blades 34 are driven to pump the filler into the connecting tube 31, thereby avoiding the possibility of the filler being blocked in the section of the telescopic tube 3 away from the mold frame 16 due to the thinner diameter of the section of the telescopic tube 3 away from the mold frame 16, thereby improving the material dropping effect of the filler.

[0112] Embodiment 2:

[0113] See also Figure 1On the basis of the first embodiment, the toggle plate 2 and the moving trolley 1 are jointly equipped with a circular frame 21, a fixed connecting frame 22 and a yielding spring rod 23.

[0114] The circular frame 21 is slidably disposed on the toggle plate 2 in the longitudinal direction and is used to remove the mud adhered to the toggle plate 2.

[0115] There are two fixed connecting frames 22 , both of which are installed on the moving vehicle 1 .

[0116] The yield spring rod 23 corresponds to the fixed connecting frame 22 one by one and is installed between the circular frame 21 and the yield spring rod 23 .

[0117] During specific operation, after the filling material inside the gap is filled, the toggle plate 2 is reset. When the toggle plate 2 is lifted, the mud adhering to the toggle plate 2 can be scraped off due to the obstruction of the circular frame 21, so as to avoid the mud adhering to the toggle plate 2 and improve the cleanliness of the surface of the toggle plate 2. When the toggle plate 2 moves horizontally, the giving way spring rod 23 can ensure that the circular frame 21 and the toggle plate 2 move synchronously.

[0118] See also Figures 7 to 9 The punching block 4 is symmetrically provided with an L-shaped moving groove 41 along its width direction, and an electric slider 42, a connecting rod 43, a scraper 45 and bristles 44 are also installed on the punching block 4.

[0119] The electric slider 42 is disposed inside the moving groove 41 and moves in the moving groove 41 , and a connecting rod 43 is installed on the electric slider 42 .

[0120] The scraper 45 is clamped inside the punching block 4 , and one end of the connecting rod 43 away from the electric slider 42 is connected to the scraper 45 .

[0121] The brush 44 and the scraper 45 are provided with a clearance groove, and the brush 44 is arranged inside the clearance groove.

[0122] During specific operation, the electric slider 42 is started to move along the vertical section of the moving groove 41. During the movement of the electric slider 42, the scraper 45 is driven by the connecting rod 43 to move out of the stamping block 4, and the end of the scraper 45 close to the connecting rod 43 is made to abut against the bottom of the stamping block 4. When the electric slider 42 moves to the horizontal section of the moving groove 41, the electric slider 42 moves along the horizontal section of the moving groove 41 and drives the scraper 45 to scrape off the filler adhered to the bottom of the stamping block 4, so as to avoid the solidification of the filler, which may cause the solidified filler in the subsequent stamping process to cause depression on the stamping surface of the filler, affecting the compaction degree of the filler.

[0123] The clearance groove can make way for the connecting pipe 31 to avoid collision between the scraper 45 and the connecting pipe 31 , and the bristles 44 can brush away the filler adhering to the bottom of the penetrating groove.

[0124] The implementation principle of the present invention is:

[0125] (1): After the moving trolley 1 is fixed and limited, the driving cylinder 13 is started. During the movement of the telescopic end of the driving cylinder 13, the linkage plate 11 is driven to move toward the pore. During the movement of the linkage plate 11, the toggle plate 2 is driven to be inserted into the pore. When the toggle plate 2 enters the pore, the driving cylinder 13 is closed and the rotating motor 14 is started. During the rotation of the output shaft of the rotating motor 14, the threaded rod 15 is driven to rotate. During the rotation of the threaded rod 15, the vertical rod 12 is driven to move along the width direction of the moving trolley 1. During the movement of the vertical rod 12, the toggle plate 2 is driven to move through the linkage frame linkage plate 11. During the movement of the toggle plate 2, the backfill soil covering the pore can be removed, thereby opening the pore.

[0126] (2): At this time, the traction rope 18 is loosened, that is, the end of the telescopic tube 3 with the counterweight 17 is not subject to tension. At this time, the counterweight 17 drives the telescopic tube 3 to extend, and the telescopic end of the telescopic tube 3 moves toward the inside of the pore. When the telescopic end of the telescopic tube 3 moves to the specified position, filler is poured into the telescopic tube 3. The filler falls to the bottom of the pore through the telescopic tube 3. At this time, the external driving force (cylinder, etc.) drives the profile frame 16 to reciprocate in the length direction of the mobile trolley 1. During the movement of the profile frame 16, the telescopic tube 3 is driven to reciprocate. During the reciprocating movement of the telescopic tube 3, the filler can be spread into the inside of the pore.

[0127] (3): When the filler is spread to a certain thickness inside the gap, the profile frame 16 drives the telescopic tube 3 to move to the rack plate 10. During the movement of the telescopic tube 3, the gear 32 cooperates with the rack plate 10 to rotate 90 degrees.

[0128] (4): When the filler is spread to a certain thickness inside the gap, the transition shaft 119 is driven to rotate by the existing motor. During the rotation of the transition shaft 119, the rotating connecting shaft 116 is driven to rotate a certain number of times through the belt transmission method. During the rotation of the rotating connecting shaft 116, the connecting rope 113 is wound around the connecting rope 113, and the connecting rope 113 drives the stamping block 4 to lift up a certain distance. At this time, the connecting rope 113 drives the vertical frame 117 to move toward the side of the stamping block 4 through the linkage shaft 118, and the reset spring rod is stretched.

[0129] At this time, the transition shaft 119 is released, and the transition shaft 119 rotates without any restraint. During the rotation of the transition shaft 119, the rotating connecting shaft 116 is driven to rotate through the belt transmission. At this time, the connecting rope 113 is no longer constrained, and the reset spring rod resets and drives the vertical frame 117 to reset. The punching block 4 moves downward due to gravity, and the punching block 4 can pass over the connecting pipe 31 to punch the flat filler.
