Description

Technical Field

[0001] This utility model belongs to the field of caisson construction technology, and in particular relates to a multi-directional water jetting device for caisson sinking and correction. Background Technology

[0002] With the continuous development of caisson construction technology, caissons often tilt during the sinking process due to uneven geological conditions or force deviations, requiring corrective measures to ensure their verticality and construction safety. Currently, a common method is to spray high-pressure water into the soil layer around the caisson wall to flush, soften, and even locally liquefy the soil, reducing lateral friction and foundation bearing capacity, thereby decreasing sinking resistance and achieving active correction.

[0003] However, traditional construction methods often use fixed single high-pressure water jet pipes, each of which can only spray water into a specific area within the caisson, resulting in limited coverage. To meet the requirements of multi-directional flushing, multiple water jet pipes are usually arranged around the caisson, leading to an increase in the number of equipment, pipeline complexity, and installation space requirements, as well as a significant increase in material and construction costs. At the same time, due to the fixed water jet angle and the spacing between pipes, it is difficult to eliminate flushing blind spots and dead angles, resulting in uneven soil softening, imbalance in frictional resistance adjustment in various directions, difficulty in achieving precise correction, and affecting the stable control of the caisson's sinking attitude.

[0004] Therefore, there is a particular need for a multi-directional water jetting device for correcting the deviation of a caisson during sinking, in order to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of traditional construction equipment, such as numerous components, complex pipelines, large space requirements, high costs, fixed water jetting angles, and uneven soil softening due to pipe spacing, resulting in unbalanced frictional resistance, difficulty in precise correction, and impact on the stability of caisson sinking, this utility model provides a multi-directional water jetting device for caisson sinking correction.

[0006] This utility model is achieved through the following technical approach: A multi-directional water jetting device for caisson sinking and correction includes a support base, a support cylinder, a water tank, a water pump, a corrugated pipe, a water spray barrel, nozzles, a sleeve, a retraction assembly, and a controller. The support cylinder is rotatably mounted on the lower part of the support base, the water tank is mounted on the upper part of the support base, the water pump is mounted on the bottom of the water tank, the pump's suction end is connected to the inside of the water tank, the corrugated pipe is mounted on the pump's discharge end, and a water spray barrel is rotatably mounted at the end of the corrugated pipe. Multiple evenly distributed nozzles are fixed to one end of the water spray barrel, with the nozzles facing different directions and arranged at an angle. The cylinder has a first sleeve that slides inside. Inside the first sleeve, three sleeves slide and nest sequentially from top to bottom, forming a four-stage telescopic structure. The last sleeve from top to bottom is slidably connected to the water spray tank. The controller is installed on one side of the upper part of the support base. The water pump is electrically connected to the controller. The retraction and extension assembly is located on the lower part of the support base and also includes a gear ring, a servo motor, and a spur gear. The gear ring is fixed to the upper part of the support cylinder. The servo motor is installed on one side of the lower part of the support base and is electrically connected to the controller. The spur gear is fixed to the output shaft of the servo motor and is located behind the gear ring and meshes with it.

[0007] In a preferred embodiment of this utility model, the take-up and release assembly includes a fixed base, a connecting rod, a take-up reel, a connecting rope, a connecting plate, a limiting ring, a worm gear, a dual-axis motor, and a worm. Multiple left-right distributed fixed bases are fixedly connected to the lower part of the support base. A connecting rod is rotatably arranged between two longitudinally aligned fixed bases. The two connecting rods are arranged side-by-side. A take-up reel is fixedly connected to the outside of each connecting rod. A connecting rope is wound around each take-up reel. A connecting plate is fixedly connected to the end of each connecting rope. A limiting ring is fixedly connected to the other end of the spray tank. The connecting plate is located inside the limiting ring and forms a sliding fit with the limiting ring. A worm gear is fixedly connected to one end of each connecting rod. The dual-axis motor is installed on the other side of the lower part of the support base. Both output shafts of the dual-axis motor are fixedly connected to worm gears, which are located below and mesh with the corresponding worm gears.

[0008] In a preferred embodiment of the present invention, the system further includes a limiting frame and guide wheels. Two limiting frames are installed at the bottom of the water tank, arranged side by side. Each limiting frame is rotatably equipped with multiple guide wheels distributed vertically. The connecting rope passes through the multiple guide wheels on the same side.

[0009] In a preferred embodiment of this utility model, the support cylinder, multiple sleeves and the water spray bucket are connected by a vertical groove and a slider sliding fit.

[0010] In a preferred embodiment of this utility model, the connecting rope is a high-strength tensile rope.

[0011] In a preferred embodiment of this invention, the axial thickness of the spur gear and the gear ring are equal.

[0012] Beneficial effects: By setting up a rotatable support cylinder, gear ring, servo motor, spur gear and retraction assembly, the water spray tank can be raised and lowered and rotated circumferentially. Combined with multi-angle nozzles spraying water synchronously, it can accurately scour the soil on the side wall of the caisson, effectively soften the soil layer, balance the lateral friction resistance, solve the problems of many blind spots and weak correction ability of traditional water spraying, and improve the control accuracy of the caisson sinking attitude and construction safety.

[0022] Example: A multi-directional water jetting device for correcting the deviation of a caisson during sinking, such as... Figures 1-6 and Figure 8As shown, the system includes a support base 1, a support cylinder 2, a water tank 3, a water pump 4, a corrugated pipe 5, a spray bucket 6, nozzles 7, a sleeve 8, a retraction assembly, and a controller 19. The support cylinder 2 is rotatably mounted on the lower part of the support base 1. The water tank 3 is bolted to the upper part of the support base 1. The water pump 4 is bolted to the geometric center of the bottom of the water tank 3. The pump's suction end extends upward and connects to the inside of the water tank 3. The corrugated pipe 5 is bolted to the downward-extending discharge end of the pump 4. The spray bucket 6 is rotatably mounted at the end of the corrugated pipe 5. The corrugated pipe 5 can fold and stretch as the spray bucket 6 moves up and down, while allowing the spray bucket 6 to rotate freely. Six evenly distributed nozzles 7 are fixedly connected to the lower end of the spray bucket 6, with the nozzles facing different directions. The nozzles 7 are tilted, enabling the spray to... Water is jetted onto the soil surrounding the caisson wall. A first sleeve 8 is slidably installed inside the support cylinder 2. Three more sleeves 8 are nested within the first sleeve 8 from top to bottom, forming a four-stage telescopic structure. The fourth sleeve 8 from top to bottom is slidably connected to the water spray tank 6. Vertical grooves and sliders are used to connect the support cylinder 2, the four sleeves 8, and the water spray tank 6. When the support cylinder 2 rotates, the vertical grooves and sliders constrain each other, ensuring that the four sleeves 8 and the water spray tank 6 rotate synchronously with the support cylinder 2. A controller 19 is bolted to the upper rear side of the support base 1. A water tank 3 is located in front of the controller 19. A water pump 4 is electrically connected to the controller 19. The controller 19 is a programmable logic controller (PLC), model Siemens S7-1215C. The DC / DC / DC converter has multiple digital input / output functions, supports automated logic control, and can centrally control multiple electrical components. The retraction assembly is located at the lower part of the support base 1 and also includes a gear ring 20, a servo motor 21, and a spur gear 22. The gear ring 20 is fixedly connected to the upper part of the support cylinder 2. The servo motor 21 is fixed to the lower rear side of the support base 1 by bolts. The output shaft of the servo motor 21 extends vertically upward and is electrically connected to the controller 19. The spur gear 22 is fixedly connected to the output shaft of the servo motor 21. The spur gear 22 is located behind the gear ring 20 and meshes with it. The axial thickness of the spur gear 22 is equal to that of the gear ring 20.

[0023] like Figures 3-6 and Figure 8As shown, the take-up and unwind assembly includes a fixed base 9, a connecting rod 10, a take-up reel 11, a connecting rope 12, a connecting plate 13, a limiting ring 14, a worm gear 16, a dual-axis motor 17, and a worm 18. Four fixed bases 9 are fixedly connected to the lower part of the support base 1, distributed horizontally. A connecting rod 10 is rotatably arranged between two longitudinally aligned fixed bases 9. Two connecting rods 10 are arranged side-by-side, and a take-up reel 11 is fixedly connected to the outside of each connecting rod 10. A connecting rope 12 is wound around each take-up reel 11. The connecting rope 12 is made of high-strength tensile rope, possessing good wear resistance and durability to prevent breakage due to pulling. Each connecting rope 12 has a connecting plate 13 fixedly connected to its end. A limiting ring 14 is fixedly connected to the upper end of the water spray tank 6. The connecting plate 13 is located inside the limiting ring 14 and forms a sliding fit with the limiting ring 14. Through the sliding fit between the connecting plate 13 and the limiting ring 14, the water spray tank 6 is allowed to rotate freely when the connecting rope 12 is kept in its original position. Each connecting rod 10 has a worm gear 16 fixedly connected to its front end. The dual-axis motor 17 is fixed to the lower front side of the support base 1 by bolts. Both output shafts of the dual-axis motor 17 are fixedly connected to worm gears 18 by couplings. The worm gears 18 are located below the corresponding worm gears 16 and are engaged with them.

[0024] like Figures 4-7 As shown, it also includes a limit frame 15 and guide wheels 151. Two limit frames 15 arranged side by side are fixed to the bottom of the water tank 3 by bolts. Each limit frame 15 is rotatably equipped with four guide wheels 151 distributed vertically. The connecting rope 12 passes through the four guide wheels 151 on the same side. Through the guiding action of the guide wheels 151, the movement trajectory of the connecting rope 12 during the winding and unwinding process is effectively restricted, preventing it from deviating or tangling, and ensuring that the winding and unwinding are smooth and orderly.

[0025] Initially, the connecting rope 12 is fully extended, and the water tank 6 is at its lowest position. The construction worker first starts the dual-axis motor 17 via the controller 19. The two output shafts of the dual-axis motor 17 drive the two worm gears 18 to rotate clockwise, causing the two worm gears 18 to mesh with the two worm wheels 16 in the forward direction. This drives the two worm wheels 16 to drive the two connecting rods 10 to rotate counterclockwise. The two winding reels 11 then rotate counterclockwise, beginning to wind up the two connecting ropes 12. During the winding process, the connecting ropes 12 pull the water tank 6 towards... When the slider of the water spray tank 6 moves upward to the top of the vertical groove of the fourth sleeve 8, the upward thrust of the water spray tank 6 is transmitted to the fourth sleeve 8, causing the fourth sleeve 8 to start moving upward. When the slider of the fourth sleeve 8 moves upward to the top of the vertical groove of the third sleeve 8, the upward thrust of the fourth sleeve 8 is transmitted to the third sleeve 8, and so on, until the slider of the first sleeve 8 moves upward to the top of the vertical groove of the support cylinder 2, the water spray tank 6 is at the highest position, and the dual-axis motor 17 is turned off. Once the water spray tank 6 is at its highest position, the support base 1 is installed on the ground, aligning the water spray tank 6 with the entrance of the caisson. Before the caisson lowering operation, the construction workers fill the water tank 3 with water, then restart the dual-shaft motor 17, controlling its two output shafts to drive the two worm gears 18 to rotate counterclockwise, causing the two worm gears 18 to mesh with the two worm wheels 16 in opposite directions, driving the two worm wheels 16 to drive the two connecting rods 10 to rotate clockwise, and the two winding reels 11 to rotate clockwise accordingly, beginning the process. Two connecting ropes 12 are released. During the release process, the water spraying bucket 6 moves downward under its own weight. When the slider of the water spraying bucket 6 moves down to the bottom of the vertical groove of the fourth sleeve 8, the downward pulling force of the water spraying bucket 6 is transmitted to the fourth sleeve 8, causing the fourth sleeve 8 to start moving downward. In this way, the water spraying bucket 6 moves downward with a large stroke. When the connecting rope 12 of a suitable length is released, the water spraying bucket 6 falls to a suitable position and the nozzle 7 is aligned with the height of the well wall at the bottom of the caisson, the dual-axis motor 17 is immediately turned off. During the caisson sinking operation, water pump 4 is started, pumping water from water tank 3 and delivering it to corrugated pipe 5. The water in corrugated pipe 5 flows into water spray tank 6 and is finally sprayed onto the soil around the caisson wall through six nozzles 7. At the same time, servo motor 21 is started, causing its output shaft to drive spur gear 22 to rotate clockwise. When spur gear 22 rotates, it meshes with gear ring 20, driving gear ring 20 to drive support cylinder 2 to rotate counterclockwise. The rotational power of support cylinder 2 is transmitted to water spray tank 6 through four sleeves 8, so that the six nozzles 7 rotate while spraying water, achieving multi-angle and all-round water spraying operation, softening the soil on the side of the caisson, and ensuring the caisson sinks smoothly. After the caisson operation is completed, water pump 4 and servo motor 21 are turned off.
