Description

Technical Field

[0001] The invention relates to the technical field of caisson construction, in particular to a caisson deviation correction device. Background Art

[0002] Caisson construction involves constructing a shaft-shaped structure made of reinforced concrete, section by section, as support for the foundation pit walls. Blades are typically placed under the first shaft section. Through mechanical and manual excavation, the shaft's gravity overcomes the frictional resistance between the shaft walls and the soil, allowing it to sink to the designed elevation, ultimately forming an underground structure or foundation. The sinking process requires controlling the speed and direction of the caisson to ensure its verticality and stability. Therefore, caisson construction is essentially the process of converting a precast structure on the surface into an underground structure by excavating and sinking it to a certain depth.

[0003] Excavation in the well is a key step in sinking the wellbore. When excavating in the well, due to many factors such as uneven soil quality, asymmetric excavation, uneven force at the blade foot and poor geology, the caisson is prone to sinking. The probability of sinking is greater for large caissons, especially in soft soil areas. If this deviation is not corrected in time, it will make the subsequent sinking of the caisson difficult, affect the final position accuracy of the structure, have an adverse impact on the project quality and construction efficiency, and may also cause casualties and property losses.

[0004] In the prior art, caisson correction is usually carried out by combining eccentric excavation in the well with pressure correction, that is, digging on one side of the well, applying pressure at the highest point above the well wall to push the wellbore downward to correct the deviation. Applying pressure at the highest point of the wellbore wall usually involves placing a weight or a hydraulic push rod to push up. However, the force of the weight-bearing method is difficult to control, and over-pressure often occurs, which increases the difficulty of correction. The hydraulic push rod structure needs to overcome the reaction force when pressing, so the base needs to be installed on the ground. The position of the wellbore offset is not exactly the same each time, and the base of the hydraulic push rod structure needs to be continuously disassembled and installed from the ground. The wellbore has a lot of overall deviations during the caisson construction process, and the installation of the base and the ground requires fixed piles driven into the ground to a certain depth. The disassembly and installation are troublesome, resulting in the correction process being extremely time-consuming and labor-intensive, affecting the progress of the project.

[0005] Chinese invention patent CN119686362A discloses a device for correcting the deviation of a caisson during construction. The device comprises a support frame, a connection module, a drive motor, a rope collection module, a lifting module, a gripper, a cable, and a ground anchor. The support frame is fixed to the ground, with the top of the support frame fixedly connected to the connection module, which is fixedly connected to the rope collection module, and the connection module slidably connected to the lifting module. The drive motor is fixedly connected to the connection module, and the drive motor is fixedly connected to the rope collection module. The lifting module applies downward pressure on the highest point, and the rope collection module pulls the gripper to apply downward tension on both ends of the highest point to prevent stress concentration and deformation of the shaft wall during correction. The support frame needs to be fixed to the ground, making it difficult to disassemble and install when relocating. Chinese invention patent CN110541427A discloses a device for correcting the deviation of a caisson shaft. The device comprises a support column, a cylinder, a piston, and a hydraulic device. The lower portion of the support column is fixedly connected to the ground outside the caisson. The upper portion of the support column is connected to the correction frame, which is annular and faces the caisson. The setting of the correction frame avoids the constant installation and disassembly of hydraulic devices, etc., but the correction frame blocks the caisson, affecting the hanging of the well shaft, and the round correction frame is large in size and not easy to be placed on a vehicle for transportation, making transportation inconvenient.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] (1) The annular base is installed on the ground through fixed piles. The jacking correction part can be moved on the annular base through the slide rail and the slider. After it reaches the highest point of the wellbore, the raised part of the wellbore is pushed down, and the wellbore is corrected by the method of digging in the well. The jacking correction part can be moved to the highest point of the wellbore on the annular base. There is no need for frequent disassembly and installation, which reduces the impact on the progress of the project. At the same time, the annular base is composed of a first arc plate and a second arc plate. After disassembly, the occupied space is greatly reduced, which is convenient for transportation on a vehicle and convenient for transshipment.

[0019] (2) The first arc plate and the second arc plate are connected by a hinge, and the hinge is located on the inner side of the annular base. When the annular base is folded up, the first arc plate is rotated to the inner side of the second arc plate through the inner hinge, which not only reduces the size in the horizontal direction but also makes it convenient for folding and unfolding. Since the inner side is a caisson, the plug-in structure is located on the outer side of the annular base, which is convenient for subsequent installation and reduces danger.

[0020] (3) The plug-in structure includes a fixed block located at one end of the second arc plate. The fixed block is provided with a through hole along the tangent direction of one end of the rotating plate. The through holes in the two fixed blocks are aligned and are penetrated by bolts. The disassembly and installation are convenient, and the entire construction process only requires one installation and disassembly, which takes a short time and has little impact on the construction progress.

[0021] (4) After the device is assembled, it is lifted by hanging the cable on the lifting ring and transported to the top of the caisson. The caisson is aligned and the operator can complete the measurement manually. The annular base is installed by fixing piles. The installation and use are relatively simple and do not take long, which has little impact on the construction progress.

[0022] (5) The hydraulic push cylinder pushes down the well wall and cooperates with the eccentric excavation in the well to achieve a good correction effect for caissons of a certain depth.

[0023] (6) The hydraulic jack rotates the turn plate so that the hydraulic push cylinder leaves the top of the wellbore and makes room for the next wellbore. After the well is excavated to the specified elevation of the wellbore, the high point of the well wall is measured, the hydraulic jack rotates the turn plate back, and the hydraulic push cylinder presses the well wall to correct the deviation.

[0024] (7) When the measuring mechanism moves one circle on the annular base, the rotating wheel will drive the slide bar to move up and down due to the height of the well wall, causing the distance between the laser transmitter and the laser receiver to change. The maximum and minimum values of the distance are recorded. Half of the difference between the two is the stroke of the correction part to press against the high well wall. At the same time, the position of the highest point is determined according to the position of the starting point of the measuring mechanism, which saves the use of the level meter and the total station. The level meter and the total station no longer need to follow up the entire construction process, which greatly saves costs and manpower and improves the effect of the correction measurement process.

[0025] (8) After the wellbore is offset, a small displacement will occur in the horizontal direction. The horizontal support rod can move axially along the linear bearing, driving the wheel frame and the rotating wheel under the outrigger to move in the horizontal direction, offsetting the horizontal displacement of the wellbore, so that the rotating wheel can move smoothly on the well wall.

[0044] In order to enable people skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example

[0046] The following is combined with Figures 1-9 The present invention is further described as follows: a caisson correction device, such as Figure 1 and Figure 2 As shown, it includes an annular base 1 located outside the caisson, a rotating and moving mechanism 3 and a jacking and correcting part 4; the annular base 1 includes two first arc plates 11 and four second arc plates 12, the two first arc plates 11 are arranged opposite to each other, and the four second arc plates 12 are respectively arranged at both ends of the first arc plate 11, and are rotatably connected to the first arc plate 11, and the two adjacent second arc plates 12 are connected by a plug-in structure 2; the annular base 1 is installed on the ground through a fixed pile 15; the first arc plate 11 and the second arc plate 12 are aligned with a slide rail 13, the rotating and moving mechanism 3 includes a slider 31 slidably connected to the slide rail 13, and a mounting plate 33 is provided on the slider 31, the jacking and correcting part 4 is located on the mounting plate 33, and the jacking and correcting part 4 includes a hydraulic push cylinder 45 for jacking the wellbore.

[0047] The annular base 1 is installed on the ground through the fixed piles 15, and the jacking correction part 4 can be moved on the annular base 1 through the slide rail 13 and the slider 31. After it reaches the highest point of the wellbore, the raised part of the wellbore is pushed downward, and the wellbore is corrected by the method of skew excavation in the well. The jacking correction part 4 can be moved to the highest point of the wellbore on the annular base 1, and there is no need for frequent disassembly and installation, which reduces the impact on the progress of the project. At the same time, the annular base 1 is composed of a first arc plate 11 and a second arc plate 12. After disassembly, the occupied space is greatly reduced, which is convenient for transportation on a vehicle and convenient for transshipment.

[0048] Two first arc plates 11 and four second arc plates 12 are assembled together to form an annular base 1, which has fewer parts and is convenient for installation and disassembly. After the second arc plates 12 are rotated, they are folded with the first arc plates 11 for easy transportation and placement. It is more convenient to operate on site and is a more preferred choice.

[0049] like Figure 1 and Figure 7 As shown, the first arc plate 11 and the second arc plate 12 are rotatably connected via a hinge, and the hinge is located on the inner side of the annular base 1. When the annular base 1 is folded up, the first arc plate 11 is rotated to the inner side of the second arc plate 12 via the inner hinge, which not only reduces the size in the lateral direction but also facilitates folding and unfolding. Since the inner side is a caisson, the plug-in structure 2 is located on the outer side of the annular base 1, which is convenient for subsequent installation and reduces danger. The plug-in structure 2 includes a fixed block 21 located at one end of the second arc plate 12. The fixed block 21 is provided with a through hole 22 along the tangential direction of one end of the rotating plate 42. The through holes 22 in the two fixed blocks 21 are aligned and are penetrated by bolts 23. Disassembly and installation are convenient, and the entire construction process only requires one installation and disassembly, which takes a short time and has little impact on the construction progress.

[0050] like Figure 1 and Figure 8 As shown, the device also includes a lifting structure 5, which includes a horizontal plate 52 and two vertical plates 51. The lower end of the vertical plate 51 is provided with a through hole 54, and the through holes 54 of the two vertical plates 51 are respectively mounted on the two ends of the bolt 23. The horizontal plate 52 is fixedly connected to the upper ends of the two vertical plates 51, and a lifting ring 53 is provided on the horizontal plate 52.

[0051] After the device is assembled, the cable is hung on the lifting ring 53 to lift the device, transport it to the top of the caisson, align it with the caisson, and the operator can complete the manual measurement, specifically: measure the diameter of the annular base 1 and the diameter of the caisson, calculate the difference, use a ruler or other tools to measure the difference to the outside of the caisson, mark the point, and take three points in total. When lifting the device, the annular base 1 falls on three points and is installed through the fixed piles 15. The installation and use are relatively simple and not complicated. It does not take long and has little impact on the construction progress. After use, the device can be lifted away and disassembled.

[0052] like Figure 3 and Figure 4 As shown, the jacking and correcting part 4 also includes a vertical plate 41, a rotating plate 42, a hydraulic jack 43 and a support frame 44. The vertical plate 41 is arranged on the outer side of the mounting plate 33, and the hydraulic jack 43 is rotatably connected to the inner side of the mounting plate 33. One end of the rotating plate 42 is rotatably connected to the vertical plate 41, and the other end is rotatably connected to the output end of the hydraulic jack 43; the support frame 44 is installed on the rotating plate 42, and the hydraulic push cylinder 45 is vertically installed on the support frame 44.

[0053] The hydraulic push cylinder 45 presses the well wall downward to correct the deviation. The reaction force is finally transmitted to the annular base 1 through the support frame 44. At the same time, in conjunction with the eccentric excavation in the well, common operations such as pouring water around the wellbore can be used to reduce friction, which is convenient for the pushing pressure of the hydraulic push cylinder 45. For caissons of a certain depth, it can achieve a good correction effect; the hydraulic top 43 rotates the rotating plate 42, so that the hydraulic push cylinder 45 leaves the top of the wellbore, and makes room for the next wellbore. After the soil in the well is excavated to the specified elevation when the wellbore sinks, the high point of the wellbore wall is measured, and the hydraulic top 43 rotates the rotating plate 42 back, and the hydraulic push cylinder 45 presses the well wall to correct the deviation.

[0054] The push rod of the hydraulic push cylinder 45 is set downward, and a pressure plate 46 is provided below the push rod to increase the contact area with the well wall and reduce stress concentration.

[0055] like Figure 2 and Figure 6 As shown, it also includes a measuring mechanism 6, which includes an outrigger 61 arranged on the rotating plate 42, a sliding sleeve 62 provided on the outrigger 61, a sliding rod 63 slidingly provided in the sliding sleeve 62, a baffle 64 provided on the upper end of the sliding rod 63, and a wheel frame 67 connected to the lower end, a rotating wheel 66 provided below the wheel frame 67, a spring 65 provided on the sliding rod 63, the upper end of the spring 65 rests on the outrigger 61, and the lower end rests on the wheel frame 67; a laser emitter 71 is provided on the outrigger 61, and a laser receiver 72 corresponding to the laser emitter 71 is provided on the wheel frame 67.

[0056] The rotating wheel 66 is driven by the wheel frame 67 to move on the wellbore wall. When it moves to the high point of the wellbore wall, the wheel frame 67 is subjected to pressure, overcoming the elastic force of the spring 65 to push the slide rod 63 upward in the vertical direction along the sleeve 62, and the distance between the laser emitter 71 and the laser receiver 72 is reduced, and the distance between the two is measured; when the rotating wheel 66 moves to the low point of the wellbore wall, the slide rod 63 slides down in the vertical direction along the sleeve 62, and the distance between the laser emitter 71 and the laser receiver 72 is increased, and the distance between the two is measured.

[0057] Therefore, the measuring mechanism 6 moves one circle on the annular base 1 driven by the rotating and moving mechanism 3, and the rotating wheel 66 will drive the slide bar 63 to move up and down due to the height of the well wall, so that the distance between the laser emitter 71 and the laser receiver 72 changes, and is recorded by the controller, etc.; through the maximum and minimum values of the distance, the difference between the highest point of the well wall and the lowest point can be known, and half of the difference between the maximum and minimum values is the stroke of the correction part 4 to press the high well wall; at the same time, the measuring mechanism 6 rotates at a constant speed on the annular base 1. After the measuring mechanism 6 starts to rotate from a starting point on the annular base 1, its position relative to the starting point can be judged according to the time when the highest point appears. After the measuring mechanism 6 rotates one circle, the correction part 4 is moved to this position to perform the correction operation; the use of the level meter and the total station is saved, and the level meter and the total station no longer need to follow up the entire construction process, which greatly saves cost and manpower and improves the effect of the correction measurement process.

[0058] The rotation process of the measuring mechanism 6 on the annular base 1 can be carried out during the interval between lifting and preparing for the next wellbore, without taking up extra time and affecting the overall construction progress. After the measurement is completed, top pressure is carried out, and then when the wellbore is placed directly above, the rotating plate 42 is rotated by the hydraulic jack 43, away from the top of the wellbore to leave space.

[0059] like Figure 6 As shown, the outrigger 61 is connected to the rotating plate 42 through a sliding portion 8. The sliding portion 8 includes a support 81 fixed on the rotating plate 42 and a horizontal support rod 83 fixed on the outrigger 61. A linear bearing 82 is horizontally provided on the support 81. The horizontal support rod 83 is slidably connected to the linear bearing 82. A stop block 84 is provided at one end of the horizontal support rod 83.

[0060] After the wellbore is deviated, Figure 9 As shown, a small displacement will occur in the horizontal direction, and the horizontal support rod 83 can move axially along the linear bearing 82, driving the wheel frame 67 and the rotating wheel 66 under the outrigger 61 to move in the horizontal direction, offsetting the horizontal displacement of the wellbore, so that the rotating wheel 66 can move smoothly on the well wall.

[0061] like Figure 5 As shown, the cross section of the slide rail 13 is T-shaped, and L-shaped baffles 32 are provided on both sides of the slider 31 to match the T-shaped slide rail 13. While performing the guide limit, it also bears the reaction force of the hydraulic push cylinder 45.

[0062] like Figure 5 As shown, a circle of racks 14 are provided on the slide rail 13, and a reserved groove 311 for accommodating the rack 14 is provided under the slider 31; a drive motor 34 is also provided in the reserved groove 311, and a drive gear 35 is provided at the output end of the drive motor 34, which engages with the rack 14.

[0063] The driving motor 34 drives the driving gear 35 to rotate, and with the cooperation of the rack 14 , the slider 31 moves on the slide rail 13 , thereby realizing the rotation of each component on the annular base 1 .
