Description

Technical Field

[0001] This utility model relates to the field of caisson technology, and in particular to a caisson vertical detection and adjustment device. Background Technology

[0002] A caisson is a structure in which a section (or the entire caisson) is first built on the ground, the soil inside is removed, and it is gradually sunk. The caisson is then extended section by section until it reaches the predetermined depth. It can be used as an underground pump house and water tank, or filled with concrete as the foundation of large bridges and heavy structures. During the sinking process, abnormal tilting may occur due to changes in soil quality, uneven friction between the caisson walls, etc. At this time, it is necessary to conduct vertical inspection and correction of the caisson.

[0003] When conducting vertical inspection and correction of caissons, the conventional technique involves using a theodolite and other electronic instruments to accurately detect vertical deviations. Correction is achieved by excavating more soil on the opposite side (higher side) of the caisson's tilt direction to reduce soil resistance, while minimizing or eliminating excavation on the same side (lower side) to maintain or increase soil resistance. This difference in soil pressure causes the caisson to tilt towards the lower side, gradually restoring its verticality. However, theodolite measurements typically require subsequent calculations. When the initial tilt is significant, repeated adjustments and multiple inspections are necessary. These multiple calculations reduce adjustment efficiency and construction efficiency. Furthermore, the large initial tilt adjustment requires substantial excavation, increasing labor intensity.

[0004] To address this, a device for vertical detection and adjustment of caissons is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting and adjusting the verticality of caissons, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical detection and adjustment device for a caisson, comprising four arc rings, with a caisson located at the bottom of each arc ring in the ground. The four arc rings divide the caisson into four equal parts and are positioned on the caisson. Each arc ring is equipped with a measurement and adjustment assembly for detecting and correcting the tilt of the caisson during sinking construction. The measurement and adjustment assembly includes a connecting frame mounted on the arc rings, on which a plumb bob and a measuring plate are fixedly installed. A high-pressure water gun is located in the caisson, and the high-pressure water gun has a nozzle.

[0007] Preferably, the caisson has four pre-drilled holes, and a bolt group is provided between the four arc rings to fix the four arc rings to the outer wall of the caisson.

[0008] Preferably, the connecting frame is fixedly connected to the arc ring, the measuring plate is provided with scale lines for angle measurement, and the suspension line on the plumb bob is attached to the measuring plate.

[0009] Preferably, a bending frame is fixedly connected to the arc ring, a slide rail groove is provided on the bending frame, a movable frame is slidably connected in the slide rail groove, and a high-pressure water gun is fixedly installed on the movable frame.

[0010] Preferably, a water pipe for connecting to the outside is fixedly connected to the high-pressure water gun, a connecting rope is fixedly connected to the mobile frame, a lifting device is provided on one side of the caisson, and the connecting rope is fixedly connected to the lifting device.

[0011] Preferably, a sliding tube is slidably connected to the high-pressure water gun, and a hydraulic cylinder is fixedly connected between the short plate on the sliding tube and the moving frame.

[0012] Preferably, a hollow conical drill bit is fixedly connected to the sliding tube, and the surface of the conical drill bit is provided with drainage holes.

[0013] The beneficial effects of this utility model are:

[0014] This invention, by setting up a measurement and adjustment component, can divide the caisson into four areas through an arc ring during the caisson construction process. When the caisson tilts, the change in angle between the plumb line and the measuring plate is used to determine the change in the verticality of the caisson. A high-pressure water gun is used to hydraulically cut the soil on the side of the caisson with higher tilt, thereby achieving the correction operation. In the initial process, the plumb line method is more convenient and faster than theodolites and other measuring methods. Combined with hydraulic cutting, it eliminates the need for manual excavation, making the correction efficiency higher. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides a vertical detection and adjustment device for a caisson, including four arc rings 1. The bottom end of the arc rings 1 is provided with a caisson 2, which is located in the ground. The four arc rings 1 divide the caisson 2 into four equal parts and are set on the caisson 2. The arc rings 1 are provided with a measurement and adjustment component for tilt detection and tilt correction of the caisson 2 during sinking construction. By setting the measurement and adjustment component, the tilt generated during the sinking process of the caisson 2 can be vertically detected, and multiple adjustments and corrections can be made to ensure the normal progress of construction. The measurement and adjustment component includes a connecting frame 3 set on the arc rings 1. A plumb bob 4 and a measuring plate 5 are fixedly installed on the connecting frame 3. A high-pressure water gun 6 is provided in the caisson 2, and a nozzle 7 is provided on the high-pressure water gun 6.

[0025] like Figures 1 to 3 As shown, specifically, a bolt group 9 is provided between the four arc rings 1. The bolt group 9 fixes the four arc rings 1 to the outer wall of the caisson 2. During the sinking construction of the caisson 2, the workers fix the four arc rings 1 at the top position of the caisson 2. The arc rings 1 are adapted to the curvature of the caisson 2, and the arc rings 1 are not tightly fitted when connected, so they can be connected and fixed to the caisson 2 by the bolt group 9. The bolt group 9 includes bolts and nuts, which are used together. The four arc rings 1 can divide the caisson 2 into four parts, and each arc ring 1 is an independent measuring part. The connecting frame 3 is fixedly connected to the arc ring 1. The measuring plate 5 is provided with scale lines 10 for angle measurement. The plumb line on the plumb line 4 is attached to the measuring plate 5. During the sinking process of the caisson 2... Due to changes in soil quality and uneven friction of the well wall, the caisson 2 tilts. At this time, the caisson 2 is not perpendicular to the ground. The tilt of the caisson 2 causes the connecting frame 3 and the measuring plate 5 to tilt as well. However, the plumb line 4 on the connecting frame 3 and the plumb line remain vertically downward under the action of gravity. The measuring plate 5 tilts, and the plumb line, which remains vertically downward, moves at an angle on the surface of the measuring plate 5. The tilt angle can be observed through the scale line 10 on the measuring plate 5. By measuring the tilt angle, the tilt angle of the caisson 2 can be determined. At the same time, the angle change between each measuring plate 5 and the plumb line in the four areas formed by the four arc rings 1 should be observed to determine which area is high or low, and thus determine the tilt of the caisson 2 and which area it is tilting towards.

[0026] like Figures 4 to 5As shown, specifically, a bending frame 11 is fixedly connected to the arc ring 1. A slide rail groove 12 is provided on the bending frame 11, and a movable frame 13 is slidably connected in the slide rail groove 12. A high-pressure water gun 6 is fixedly installed on the movable frame 13, and a water pipe 14 for external connection is fixedly connected to the high-pressure water gun 6. A connecting rope 15 is fixedly connected to the movable frame 13. A lifting device 16 is provided on one side of the caisson 2, and the connecting rope 15 is fixedly connected to the lifting device 16. During the above process, it is determined which area the caisson 2 is facing. After the area is tilted, the lifting device 16 and the connecting rope 15 are used to place the moving frame 13 into the symmetrical area of ​​the tilted position of the caisson 2, that is, the position of the higher side of the well wall after the caisson 2 is tilted. The moving frame 13 is then placed into the slide rail groove 12 on the bending frame 11 in the corresponding area. The caisson 2 is provided with four reserved holes 8. The moving frame 13 moves downward in the slide rail groove 12, thereby causing the moving frame 13 to drive the high-pressure water gun 6 to move downward and to the position corresponding to the reserved hole 8.

[0027] The water pipe 14 on the high-pressure water gun 6 is connected to an external water supply device. A sliding tube 17 is slidably connected to the high-pressure water gun 6. A hydraulic cylinder 18 is fixedly connected between the short plate on the sliding tube 17 and the moving frame 13. The hydraulic cylinder 18 is a model that can be controlled independently. A hollow conical drill bit 19 is fixedly connected to the sliding tube 17, and a drain hole 20 is opened on the surface of the conical drill bit 19. When the hydraulic cylinder 18 is activated, it pushes the sliding tube 17 to move on the high-pressure water gun 6, so that the sliding tube 17 and the conical drill bit 19 gradually enter the reserved hole 8. Afterward, the drill bit 19 is inserted into the soil that adheres to the outer wall of the caisson 2. It is important to note that during insertion, the high-pressure water gun 6 is supplied with water in advance via an external water supply system. This allows the high-pressure water to be discharged through the drainage hole 20 on the conical drill bit 19. The continuous discharge of high-pressure water from the drainage hole 20 prevents soil from clogging the drainage hole 20 during insertion. Once inserted, the high-pressure water from the high-pressure water gun 6 continuously cuts and breaks through the soil on the side of the caisson 2 that is tilted higher. The soil is broken up and cleared to reduce the frictional resistance of the well wall on that side. Because the frictional resistance on the higher side of the caisson 2 is reduced, the sinking speed on that side will increase under the weight of the caisson 2, while the sinking speed on the other side will be relatively slower. This creates a pressure difference between the two sides of the caisson 2, causing the caisson 2 to tilt towards the lower side, thus correcting its deviation. During the correction process, the angle change of the plumb line 4 is observed. The mud generated by the soil cutting flows out at the bottom of the caisson 2 and is subsequently extracted using external mud extraction equipment. After the correction operation is completed, the moving frame 13 and the high-pressure water gun 6 are lifted by the lifting device 16. The caisson 2 is removed from the slide rail groove 12 and, during the subsequent sinking process, is again tilted using a plumb line 4. A high-pressure water gun 6 is then used to cut and correct the tilt. While the plumb line 4 has some error compared to a theodolite for measuring the tilt angle, this error will not have a substantial impact on the verticality control of the caisson 2 in the initial stages. On the contrary, it makes construction faster and the correction of the caisson 2 more efficient. Later, as the caisson 2 is nearing completion, a theodolite and other instruments are used for final adjustments, ensuring the proper construction of the caisson 2.
