Description

Technical Field

[0001] The invention belongs to the field of building construction, in particular to a caisson deviation correction construction method. Background Art

[0002] Caisson is a common construction technology for underwater construction. It is mostly used in bridge foundation construction. There are square, round, oval and other forms. During construction, the first section is poured in advance, and the bottom is hollowed out after solidification. The concrete block begins to sink, and then the top is poured. After completion, it is hollowed out again, and the cycle repeats until the bottom of the foundation is excavated. It consists of walls, partitions, and supports.

[0003] During the caisson sinking process, the soil hardened (from plain fill {ground to 5.0m below ground} to fully weathered granite {5.0m below ground to 8.5m below ground} and then to strongly weathered granite {8.5m below ground to 15m below ground}), which made it difficult to sink the caisson and caused uneven settlement of the caisson, causing the caisson to tilt in the north-south direction.

[0004] Existing correction methods often require the use of large machinery to carry out the correction work, which is time-consuming and costly, and it is difficult for large machinery to enter some special terrains.

[0005] To this end, the present invention provides a caisson deviation correction construction method. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a caisson deviation correction construction method described in the present invention has the following specific steps:

[0008] S1: After the caisson deflects during its falling process, connect the steel beam to the top of the caisson. The length of the steel beam should be longer than the diameter of the caisson.

[0009] S2: Place a stabilizing plate on one side of the caisson, and place a hydraulic oil pump on top of the stabilizing plate. Align the top of the hydraulic oil pump with the bottom of the steel beam, start the hydraulic oil pump, and push the steel beam up, thereby pushing the caisson back to a vertical state;

[0010] S3: The three grab arms in the stabilizing plate are used to firmly fix the hydraulic oil pump on the stabilizing plate, so that the lifting process can run smoothly;

[0011] Through this method, for caissons that deviate during sinking due to their own weight, the caisson can be corrected without the use of large-scale machinery. At the same time, with the setting of a rotatable grabbing arm, the hydraulic oil pump can be tightly grasped, reducing the problem of the hydraulic oil pump deviating outward during the jacking process.

[0012] Preferably, three storage grooves are provided at the top of the stabilizing plate, and a placing plate is slidably connected to the top of the stabilizing plate, and a spring is fixedly installed between the placing plate and the stabilizing plate, and the inner side of the storage groove is rotatably connected with a gear, and a grab arm is fixedly installed at one end of the gear, and a plurality of groups of racks are fixedly installed on the outer side of the placing plate, and the racks are meshed with the gears. As the hydraulic oil pump is placed on the placing plate, the placing plate will sink, and the meshing transmission of the gears and the racks can drive the three groups of gears and the grab arms to rotate, so that the outer side of the hydraulic oil pump can be firmly fixed, and as the hydraulic oil pump works, the downward pressure increases, which can make the three groups of grab arms move closer to the center with greater and greater force, thereby reducing the problem of the hydraulic oil pump easily deviating to the outside during the jacking process due to the inclined state of the steel beam, thereby ensuring the smooth progress of the jacking.

[0013] Preferably, one side of the stabilizing plate is rotatably connected to a folding plate, a through hole is provided at the top of the folding plate, an underground rope is provided on the outer side of the folding plate, the underground rope passes through the through hole, and a plurality of unfolding disks are fixedly installed on the outer side of the underground rope. In conjunction with the setting of the folding plate, the folding plate is first flipped upward, and then a hole is dug in the ground, and the underground rope is buried in the hole, and the top of the buried rope is passed through the through hole and fixedly connected to the through hole. Through this setting, the problem of one side of the stabilizing plate being lifted up during the jacking process can be effectively reduced, further ensuring the smooth progress of the correction process.

[0014] Preferably, a plurality of buffer grooves are provided on one side of the grabbing arm, and a squeezing arm is slidably connected to the inner side of the buffer groove. Two groups of springs are fixedly installed between the squeezing arm and the buffer groove. Combined with the setting of the slidable squeezing arm, a buffer is provided for the connection process between the grabbing arm and the hydraulic oil pump, thereby reducing damage to the hydraulic oil pump during the fixing process. At the same time, the slidable setting allows the squeezing arm to adapt to the external shape of the hydraulic oil pump, thereby more firmly locking various types of hydraulic oil pumps.

[0015] Preferably, a plurality of transfer grooves are provided on the inner side of the grabbing arm, and the transfer grooves are located on one side of the buffer groove. A communicating flow groove is provided between the transfer grooves and the buffer grooves. Liquid is provided on the inner side of the buffer groove. In combination with the setting of the transfer grooves and the liquid, the liquid may be hydraulic oil. In combination with this setting, when the squeezing arm is just squeezed, part of the liquid will be squeezed into the transfer groove to provide a buffering effect. When the squeezing reaches the limit, the supporting force is provided by the liquid and the inner wall of the grabbing arm. Compared with the squeezing spring 1, the durability is better, it is not easy to be damaged, and it can withstand a greater squeezing force.

[0016] Preferably, a metal sheet is provided at the top of the squeezing arm, and both ends of the metal sheet are fixedly connected to the top of the squeezing arm. With the arrangement of the metal sheet, when the squeezing arm is squeezed, the metal sheet at the end will be squeezed first, and the bent metal sheet will be deformed after squeezing and folded and stacked at the end of the squeezing arm. Through this arrangement, a buffer is provided for the initial contact, and in the subsequent extrusion process, the metal sheet is in a compacted state and will not hinder the normal operation of the squeezing arm.

[0017] Preferably, three groups of rotating rods are fixedly installed on the outer side of the unfolding disk, and the outer side of the rotating rod is rotatably connected with an unfolding piece, the unfolding piece is arranged in an arc shape, and a pulling component is arranged on the inner side of the unfolding piece. When the buried rope is buried in the ground and is subjected to a pulling force, the unfolding piece will unfold outward and effectively hook the soil in combination with the arc-shaped setting and the rotating connection setting of the unfolding piece, thereby further improving the function of the stabilizing plate being stably placed on the ground and allowing the lifting process to proceed smoothly. The pulling component can retract the unfolding piece inward to facilitate the subsequent recovery process.

[0018] Preferably, the pulling assembly includes a center rope, which is located in the middle of the buried rope, and the bottom end of the center rope is fixedly connected to the bottom end of the buried rope, a handle is fixedly installed on the top of the center rope, and two blocking rods are fixedly installed on the outer side of the buried rope near the top, and a connecting rope is fixedly connected between the center rope and the unfolding piece. When the buried rope needs to be recovered, the handle is pulled upward to move the center rope upward, so that the connecting rope can pull the unfolding piece back to retract the unfolding piece, and then the buried rope can be pulled out as a whole, thereby facilitating the subsequent recovery process.

[0019] Preferably, the middle part of the unfolding piece is open, and the middle part of the unfolding piece is rotatably connected to two groups of flip doors, and an insertion block is slidably connected between the two flip doors. One end of the insertion block is fixedly connected to the connecting rope. When the connecting rope is pulled, the insertion block will be pulled and moved first, thereby releasing the restraints on the two flip doors. At this time, after the insertion block moves to the limit, it will drive the unfolding piece to move back. Through this arrangement, the resistance of the recovery process of the unfolding piece is greatly reduced, which further facilitates the recovery of the unfolding piece.

[0020] Preferably, a hook groove is formed at the end of one of the grabbing arms, the hook groove is arranged in an arc shape, and an anti-sliding block is fixedly installed on the inner side of the hook groove. As the insertion block is pulled to the limit, the extended handle is connected to the hook groove. At this time, the center rope passes through the top of the hydraulic oil pump. At this time, the hydraulic oil pump is started to push up, so that the center rope can be pulled out upward, which further facilitates the recovery process of the buried rope.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The invention discloses a method for rectifying the deviation of a caisson. Through this method, the caisson that deviates during sinking under its own weight can be rectified without using large-scale machinery. At the same time, with the setting of a rotatable grabbing arm, the hydraulic oil pump can be tightly grasped, thereby reducing the problem of the hydraulic oil pump deviating outward during the jacking process.

[0023] 2. The caisson correction construction method described in the present invention, through the setting of the folding plate, first flip the folding plate upwards, then dig a hole in the ground, bury the buried rope in the hole, and pass the top end of the buried rope through the through hole and fixedly connected with the through hole. Through this setting, the problem of one side of the stabilizing plate lifting up during the jacking process can be effectively reduced, further ensuring the smooth progress of the correction process.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1 As shown, a caisson deviation correction construction method according to an embodiment of the present invention comprises the following specific steps:

[0036] S1: After the caisson deflects during its falling process, connect the steel beam to the top of the caisson. The length of the steel beam should be longer than the diameter of the caisson.

[0037] S2: Place the stabilizing plate 1 on one side of the caisson, and place a hydraulic oil pump above the stabilizing plate 1, align the top of the hydraulic oil pump with the bottom of the steel beam, start the hydraulic oil pump, push the steel beam up, and then push the caisson back to a vertical state;

[0038] S3: The three groups of grab arms 8 in the stabilizing plate 1 are used to firmly fix the hydraulic oil pump on the stabilizing plate 1 so that the lifting process can run smoothly;

[0039] Through this method, the caisson that deviates during sinking due to its own weight can be corrected without using large-scale machinery. At the same time, with the setting of the rotatable grabbing arm 8, the hydraulic oil pump can be tightly grasped, reducing the problem of the hydraulic oil pump deviating outward during the jacking process.

[0040] like Figures 2 to 3As shown, three storage grooves 2 are provided at the top of the stabilizing plate 1, and a placing plate 3 is slidably connected to the top of the stabilizing plate 1, a spring 23 is fixedly installed between the placing plate 3 and the stabilizing plate 1, the inner side of the storing groove 2 is rotatably connected with a gear 10, one end of the gear 10 is fixedly installed with a grabbing arm 8, and the outer side of the placing plate 3 is fixedly installed with a plurality of groups of card racks, and the card racks and the gear 10 are meshed with each other. During operation, as the hydraulic oil pump is placed on the placing plate 3, the placing plate 3 will sink, and the meshing transmission of the gear 10 and the card rack can drive the three groups of gears 10 and the grabbing arm 8 to rotate, so that the outer side of the hydraulic oil pump can be firmly fixed, and as the hydraulic oil pump works, the downward pressure increases, which can make the three groups of grabbing arms 8 move closer to the center with greater and greater force, thereby reducing the problem that the hydraulic oil pump is easily offset to the outside during the jacking process due to the inclined state of the steel beam, thereby ensuring the smooth progress of the jacking.

[0041] like Figure 2 As shown, one side of the stabilizing plate 1 is rotatably connected to a folding plate 4, the top of the folding plate 4 is provided with a through hole, and an underground rope 6 is arranged on the outer side of the folding plate 4, the buried rope 6 passes through the through hole, and a plurality of unfolding disks 7 are fixedly installed on the outer side of the buried rope 6. During operation, due to the large mass of the caisson, the hydraulic oil pump needs to be placed at a position closer to the caisson to prevent the force arm from being too large, which causes the steel beam to bend and break. This will make it easy for the other side of the stabilizing plate 1 to tilt upward when the hydraulic oil pump is pushed up. At this time, in conjunction with the setting of the folding plate 4, the folding plate 4 is first flipped upward, and then a hole is dug in the ground, and the buried rope 6 is buried in the hole, and the top of the buried rope 6 is passed through the through hole and fixedly connected to the through hole. Through this setting, the problem of one side of the stabilizing plate 1 being lifted up during the pushing process can be effectively reduced, further ensuring the smooth progress of the correction process.

[0042] like Figure 3 to Figure 4 As shown, a plurality of buffer grooves 13 are provided on one side of the grabbing arm 8, and a squeezing arm 14 is slidably connected to the inner side of the buffer groove 13. Two groups of springs 15 are fixedly installed between the squeezing arm 14 and the buffer groove 13. When working, the setting of the slidable squeezing arm 14 is used to provide a buffer for the connection process between the grabbing arm 8 and the hydraulic oil pump, thereby reducing the damage to the hydraulic oil pump during the fixing process. At the same time, the slidable setting allows the squeezing arm 14 to adapt to the external shape of the hydraulic oil pump, thereby more firmly locking various types of hydraulic oil pumps.

[0043] like Figure 4As shown, a plurality of transfer grooves 11 are provided on the inner side of the grabbing arm 8, and the transfer grooves 11 are located on one side of the buffer groove 13. A communicating flow groove 12 is provided between the transfer grooves 11 and the buffer groove 13, and a liquid is provided on the inner side of the buffer groove 13. When working, in combination with the setting of the transfer grooves 11 and the liquid, the liquid may be hydraulic oil. In combination with this setting, when the squeezing arm 14 is just squeezed, part of the liquid will be squeezed into the transfer groove 11 to provide a buffering effect. When the squeezing reaches the limit, the supporting force is provided by the liquid and the inner wall of the grabbing arm 8. Compared with the squeezing spring 15, the durability is better, it is not easy to be damaged, and it can withstand a greater squeezing force.

[0044] like Figure 4 As shown, a metal sheet 16 is provided at the top of the squeezing arm 14, and both ends of the metal sheet 16 are fixedly connected to the top of the squeezing arm 14. During operation, in conjunction with the setting of the metal sheet 16, when the squeezing arm 14 is squeezed, the metal sheet 16 at the end will be squeezed first, and the bent metal sheet 16 will be deformed after squeezing and folded and stacked at the end of the squeezing arm 14. Through this setting, a buffer is provided for the initial contact, and in the subsequent squeezing process, the metal sheet 16 is in a compacted state and will not hinder the normal operation of the squeezing arm 14.

[0045] like Figure 5 to Figure 6 As shown, three groups of rotating rods 21 are fixedly installed on the outer side of the unfolding disk 7, and the outer side of the rotating rod 21 is rotatably connected with an unfolding piece 18, and the unfolding piece 18 is arranged in an arc shape, and a pulling component is arranged on the inner side of the unfolding piece 18. During operation, when the buried rope 6 is buried in the ground and is subjected to a pulling force, the arc-shaped setting and the rotating connection setting of the unfolding piece 18 will cause the unfolding piece 18 to unfold outward and effectively hook the soil, thereby further improving the function of the stabilizing plate 1 to be stably placed on the ground and allowing the lifting process to proceed smoothly, and the pulling component can retract the unfolding piece 18 inward to facilitate the subsequent recovery process.

[0046] like Figure 5 to Figure 6 As shown, the pulling assembly includes a center rope 19, which is located in the middle of the buried rope 6, and the bottom end of the center rope 19 is fixedly connected to the bottom end of the buried rope 6, a handle 5 is fixedly installed on the top of the center rope 19, and two blocking rods are fixedly installed on the outer side of the buried rope 6 near the top, and a connecting rope 17 is fixedly connected between the center rope 19 and the unfolding piece 18. During operation, when the buried rope 6 needs to be recovered, the handle 5 is pulled upward to move the center rope 19 upward, so that the connecting rope 17 can pull the unfolding piece 18 back to retract the unfolding piece 18, and then the buried rope 6 is pulled out as a whole, thereby facilitating the subsequent recovery process.

[0047] like Figure 5 to Figure 6As shown, the middle part of the unfolding piece 18 is open, and the middle part of the unfolding piece 18 is rotatably connected with two sets of flip doors 22, and an insertion block 20 is slidably connected between the two flip doors 22, and one end of the insertion block 20 is fixedly connected to the connecting rope 17. During operation, when the connecting rope 17 is pulled, the insertion block 20 will be pulled and moved first, and then the two flip doors 22 will be freed from restraint. At this time, since the insertion block 20 moves to the limit, it will drive the unfolding piece 18 to move back. Through this arrangement, the resistance of the recovery process of the unfolding piece 18 is greatly reduced, and the recovery of the unfolding piece 18 is further facilitated.

[0048] like Figure 3 As shown, a hook groove 9 is provided at the end of one of the grab arms 8, and the hook groove 9 is arranged in an arc shape, and an anti-sliding block is fixedly installed on the inner side of the hook groove 9. During operation, as the insertion block 20 is pulled to the limit, the extended handle 5 is connected to the hook groove 9. At this time, the center rope 19 passes through the top of the hydraulic oil pump. At this time, the hydraulic oil pump is started to push up, so that the center rope 19 is pulled out upward, which further facilitates the recovery process of the buried rope 6.

[0049] During operation, as the hydraulic oil pump is placed on the placement plate 3, the placement plate 3 will sink, and the meshing transmission of the gear 10 and the card rack can drive the three sets of gears 10 and the grabbing arm 8 to rotate, so that the outer side of the hydraulic oil pump can be firmly fixed, and as the hydraulic oil pump works, the downward pressure increases, which can make the three sets of grabbing arms 8 move closer to the center with greater and greater force, reducing the problem of the hydraulic oil pump easily deviating to the outside during the jacking process due to the inclined state of the steel beam, thereby ensuring the smooth progress of the jacking; during operation, due to the large mass of the caisson, the hydraulic oil pump needs to be placed in a position closer to the caisson to prevent the force arm from being too large, causing the steel beam to bend and break, which will make the stabilizing plate 1 when the hydraulic oil pump is jacked up. The other side of the folding plate 4 is easy to be tilted up. At this time, in conjunction with the setting of the folding plate 4, the folding plate 4 is first flipped upward, and then a hole is dug in the ground, and the buried rope 6 is buried in the hole, and the top of the buried rope 6 passes through the through hole and is fixedly connected to the through hole. Through this setting, the problem of one side of the stabilizing plate 1 being lifted up during the jacking process can be effectively reduced, and the smooth progress of the deviation correction process is further ensured; when working, in conjunction with the setting of the slidable squeezing arm 14, a buffer is provided for the connection process between the grabbing arm 8 and the hydraulic oil pump, reducing the damage to the hydraulic oil pump during the fixing process. At the same time, the slidable setting allows the squeezing arm 14 to adapt to the external shape of the hydraulic oil pump, thereby more firmly locking various styles of hydraulic oil pumps; when working , with the setting of the transfer groove 11 and the liquid, the liquid can be hydraulic oil. With this setting, when the squeezing arm 14 is just squeezed, part of the liquid will be squeezed into the transfer groove 11 to provide a buffering effect. When the squeezing reaches the limit, the liquid and the inner wall of the grabbing arm 8 provide supporting force. Compared with the squeezing spring 15, it has better durability, is not easy to be damaged, and can withstand a greater squeezing force; when working, with the setting of the metal sheet 16, when the squeezing arm 14 is squeezed, the metal sheet 16 at the end will be squeezed first, and the bent metal sheet 16 will be deformed after squeezing, and folded and stacked at the end of the squeezing arm 14. Through this setting, a buffer is provided for the initial contact, and in the subsequent squeezing process, the metal sheet 16 is in a compressed state. The solid state will not hinder the normal operation of the squeezing arm 14; during operation, when the buried rope 6 is buried in the ground, when it is subjected to a pulling force, the arc setting and the rotating connection setting of the unfolding piece 18 will cause the unfolding piece 18 to unfold outward and effectively hook the soil, further improving the function of the stable plate 1 being placed on the ground, allowing the top-up process to proceed smoothly, and the pulling component can retract the unfolding piece 18 inward to facilitate the subsequent recovery process; during operation, when it is necessary to recover the buried rope 6, the handle 5 is pulled upward to move the center rope 19 upward, so that the connecting rope 17 can pull the unfolding piece 18 back to retract the unfolding piece 18, and then the buried rope 6 is pulled outward as a whole, thereby facilitating the subsequent recovery process;During operation, when the connecting rope 17 is pulled, the insertion block 20 will be pulled and moved first, and then the two flip doors 22 will be freed from restraint. At this time, since the insertion block 20 moves to the limit, it will drive the expansion piece 18 to move back. Through this setting, the resistance of the recovery process of the expansion piece 18 is greatly reduced, which further facilitates the recovery of the expansion piece 18; during operation, as the insertion block 20 is pulled to the limit, the extended handle 5 is connected to the hook groove 9, and the center rope 19 passes through the top of the hydraulic oil pump. At this time, the hydraulic oil pump is started to push up, so that the center rope 19 is pulled upward, which further facilitates the recovery process of the buried rope 6. ;
