Description

Technical Field

[0001] This invention relates to the field of steel pipe pile equipment technology, specifically to a method for constructing steel pipe piles into rock in undulating bare rock environments. Background Technology

[0002] Mid-span bridges or platforms often require steel pipe piles as supporting foundations. The conventional method is to drive them with a vibratory hammer to meet the bearing capacity requirements. A necessary condition for using vibratory hammer driving is that the driving location must have a certain thickness of overburden. For shallow overburden, bare rock, or geological conditions such as pebbles, boulders, or drift rocks, it is not possible to achieve this using vibratory hammer driving. In such cases, artificial overburden or pre-drilled piles are required. The specific implementation process includes: transporting a heavy hammer or impact drill to the pile location, first driving a steel casing, then using the steel casing as a guide to drill a hole inside the casing with a heavy hammer or impact drill, and finally pouring concrete to anchor the steel pipe pile. Positioning requires the use of steel casing for pilot holes, and the waste generated during the pilot hole process is difficult to clean, resulting in low construction efficiency. Moreover, after pilot hole drilling, water injection, concrete laying, and soil anchoring are still required, consuming a lot of materials and increasing construction costs. There are two main methods for deep-water foundation interlocking steel pipe pile driving operations in bare rock riverbeds: one is the traditional impact drilling method, which requires processes such as installing casings, mud wall protection, and slag removal, making the construction process complex and inefficient; the other is the underwater blasting method, which is easily restricted by navigation, flood control, building and water resource protection, making blasting operations impossible, thus resulting in greater construction difficulty and lower construction efficiency.

[0003] The uneven surface of the bare rock at the bottom of the existing riverbed, as well as the hardness of the rock, prevents the steel pipe piles from sinking and contacting the top of the bare rock. Therefore, it is necessary to design an underwater rock-breaking mechanism at the bottom of the steel pipe piles to make the top of the rock horizontal, which will facilitate the construction of the steel pipe piles. Summary of the Invention

[0004] The purpose of this invention is to provide a method for constructing steel pipe piles in undulating bare rock environments, in order to solve the problems mentioned in the background art.

Positioning brackets will be welded and placed on the ship's side on the drilling side to ensure accuracy.

[0014] The screening mechanism includes a first support block fixedly connected to the top of the rotating cylinder. A sliding groove plate is slidably connected to the side wall of the first support block. A second support block is slidably connected to the inner wall of the sliding groove plate.

[0015] Furthermore, the screening mechanism also includes a movable circular plate fixedly connected to the bottom of the second support block, and the side wall of the movable circular plate is provided with a water inlet hole.

[0016] Furthermore, the side wall of the rotating shaft is provided with a crushing mechanism, which includes an inclined circular rotating plate fixedly connected to the side wall of the rotating shaft. A crushing rod is slidably connected to the side wall of the inclined circular rotating plate. A crushing groove is opened on the side wall of the crushing rod, and the inner wall of the crushing groove is slidably connected to the side wall of the inclined circular rotating plate.

[0017] Furthermore, the crushing mechanism also includes a movable chute formed on the side wall of the crushing rod, a limiting slide rod slidably connected to the inner wall of the movable chute, a limiting support plate fixedly connected to both ends of the limiting slide rod, the side wall of the limiting support plate fixedly connected to the inner wall of the supporting pipe, and a crushing drill bit fixedly connected to the bottom of the crushing rod.

[0018] Furthermore, a crushing mechanism is provided at the bottom of the rotating shaft. The crushing mechanism includes a rotating rod fixedly connected to the bottom of the rotating shaft. A connecting shaft is rotatably connected to the side wall of the rotating rod. A crushing rod is fixedly connected to the side wall of the connecting shaft.

[0019] Furthermore, the crushing mechanism also includes teeth meshing with the sidewalls of the gears, a support circular plate fixedly connected to the sidewalls of the teeth, a support seat fixedly connected to the sidewalls of the support circular plate, and the end of the support seat away from the support circular plate fixedly connected to the inner wall of the support pipe.

[0020] Furthermore, a rotating plate is fixedly connected to the side wall of the rotating rod, an arc-shaped push plate is fixedly connected to the bottom of the rotating plate, a sliding circular groove plate is provided in contact with the side wall of the arc-shaped push plate, the top of the sliding circular groove plate is fixedly connected to the bottom of the supporting pipe, and the inner wall of the sliding circular groove plate is slidably connected to the side wall of the connecting rotating shaft.

[0021] The present invention has the following beneficial effects:

[0022] 1. This method for constructing steel pipe piles in undulating bare rock environments involves moving the equipment to the required position. To adapt to frequent crushing in multiple locations, a support frame and connecting sleeve support the servo motor, thereby increasing the overall stability of the equipment during operation and reducing the shaking generated by the servo motor. This facilitates subsequent crushing. The servo motor rotates, driving the rotating shaft to rotate, which in turn drives the inclined circular plate to rotate. This causes the inclined circular plate to slide on the extrusion groove. During the sliding process, the extrusion rod descends and slides on the limiting slide rod through the moving groove. The limiting support plate supports the limiting slide rod, allowing the extrusion rod to generate a downward force that drives the crushing drill bit to crush the rock. This rock crushing facilitates the construction of steel pipe piles, ensuring that the top of the rock is in a horizontal state, which is convenient for steel pipe pile construction.

[0023] 2. In this method for constructing steel pipe piles in undulating bare rock environments, when the rotating shaft rotates, it drives the rotating rod to rotate, thereby causing the connecting shaft to rotate. The gear on the connecting shaft moves on its teeth, allowing the connecting shaft to rotate. During this movement, the crushing rod on the connecting shaft rotates, breaking up the rock and making it flat. Simultaneously, as the rotating rod rotates, it drives the rotating plate to rotate, which in turn drives the arc-shaped push plate to rotate. This causes the arc-shaped push plate to push the broken rock away from the inside of the support pipe. Furthermore, as the arc-shaped push plate rotates, it can grind the rock to make it flat, ensuring that the top of the rock is horizontal. This further facilitates the construction of the steel pipe piles and makes it easier for the steel pipe piles to contact the top of the bare rock during sinking.

[0024] 3. In this method of constructing steel pipe piles in undulating bare rock environments, during the crushing process, dust and broken rock fragments are dispersed in the water, causing rock debris to remain inside the steel pipe pile and hindering subsequent concrete pouring. The rotating shaft drives the spiral plate to rotate, thereby sucking the rock debris dispersed in the water into the support pipe. Water enters from the outside of the rotating cylinder through the dust baffle, and the water is filtered through the screening holes. The filtered rock debris is concentrated between the moving circular plate and the support pipe. The rotating rod drives the connecting scraper to scrape the inner wall of the support pipe, thereby discharging the internal debris from the top of the support pipe, which facilitates the construction of the steel pipe pile.

[0025] 4. In this method of constructing steel pipe piles in undulating bare rock environments, during the breaking process, the return spring drives the second support block to move inward, so that the moving circular plate can fit into the rotating cylinder. The moving circular plate blocks the screening holes on the rotating cylinder, which facilitates concrete pouring and the construction of the steel pipe piles.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0044] S3: After drilling, the slag is cleaned to meet the standards, the guide pipe is installed, the concrete is mixed on the ship, loaded with a hopper, and lifted by a floating crane. The anchoring concrete of each steel pipe pile is poured in one go.

[0047] An underwater rock breaking device for steel pipe pile driving in undulating bare rock environments includes a support pipe 1, a support frame 101 fixedly connected to the side wall of the support pipe 1, a connecting sleeve 102 fixedly connected to the side wall of the support frame 101, and a servo motor 103 fixedly connected to the inner wall of the connecting sleeve 102. The support frame 101 and the connecting sleeve 102 support the servo motor 103, thereby increasing the stability of the overall equipment during operation, reducing the shaking generated by the servo motor 103 during operation, and facilitating subsequent breaking. It also includes:

[0048] The conveying and cleaning mechanism includes a rotating shaft 201 fixedly connected to the output end of a servo motor 103. A spiral rotating plate 202 is fixedly connected to the side wall of the rotating shaft 201. A connecting rotating rod 203 is fixedly connected to the side wall of the rotating shaft 201. A rotating cylinder 204 is fixedly connected to the bottom of the connecting rotating rod 203. A screening hole 205 is opened on the side wall of the rotating cylinder 204.

The side wall of the connecting scraper 206 is in close contact with the inner wall of the supporting pipe 1. A dust baffle 207 is fixedly connected to the inner wall of the rotating cylinder 204. The end of the rotating shaft 201 away from the servo motor 103 passes through the dust baffle 207. At the top of the 7th shaft and extending outwards, during the crushing process, dust and broken rocks are scattered in the water, causing rock fragments to remain inside the steel pipe pile, hindering the subsequent pouring of concrete. The rotating shaft 201 drives the spiral rotating plate 202 to rotate, thereby sucking the rock fragments scattered in the water into the support pipe 1. Water enters from the outside of the rotating cylinder 204 through the dust baffle 207, and the screening hole 205 filters the water. The filtered rock fragments are concentrated between the moving circular plate 305 and the support pipe 1. The connecting rotating rod 203 rotates, driving the connecting scraper 206 to scrape the inner wall of the support pipe 1, thereby causing the internal fragments to be discharged from the top of the support pipe 1.

The screening mechanism also includes a movable circular plate 305 fixedly connected to the bottom of the second support block 303. A water inlet hole 306 is opened on the side wall of the movable circular plate 305. During crushing, the return spring 304 drives the second support block 303 to move inward, so that the movable circular plate 305 can fit against the rotating cylinder 204. The movable circular plate 305 blocks the screening hole 205 on the rotating cylinder 204, which facilitates the pouring of concrete.

A crushing rod 402 is slidably connected to the side wall of the inclined circular rotating plate 401. A crushing groove 403 is formed on the side wall of the crushing rod 402. The inner wall of the crushing groove 403 is slidably connected to the side wall of the inclined circular rotating plate 401. The crushing mechanism also includes a movable groove 404 formed on the side wall of the crushing rod 402. A limiting slide rod 405 is slidably connected to the inner wall of the movable groove 404. A limiting support plate 406 is fixedly connected to both ends of the limiting slide rod 405. The side wall of the limiting support plate 406 is slidably connected to the inner wall of the limiting support plate 405. The inner wall of the support pipe 1 is fixedly connected, and the bottom of the extrusion rod 402 is fixedly connected to the crushing drill bit 407. The servo motor 103 rotates, and the servo motor 103 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the inclined circular plate 401 to rotate, so that the inclined circular plate 401 slides on the extrusion groove 403. During the sliding process, the extrusion rod 402 descends. The extrusion rod 402 slides on the limiting slide rod 405 through the moving slide 404. The limiting support plate 406 supports the limiting slide rod 405, so that the extrusion rod 402 can generate a downward force to drive the crushing drill bit 407 to crush the rock.

[0053] A crushing mechanism is provided at the bottom of the rotating shaft 201. The crushing mechanism includes a rotating rod 501 fixedly connected to the bottom of the rotating shaft 201.

The crushing mechanism also includes teeth 506 meshing with the side wall of the gear 505. A supporting circular plate 507 is fixedly connected to the side wall of the teeth 506.

The end of the supporting seat 508 away from the supporting circular plate 507 is fixedly connected to the inner wall of the supporting pipe 1. A rotating plate 509 is fixedly connected to the side wall of the rotating rod 501. An arc-shaped push plate 510 is fixedly connected to the bottom of the rotating plate 509. A sliding circular groove plate 511 is provided in contact with the side wall of the arc-shaped push plate 510. The top of the circular groove plate 511 is fixedly connected to the bottom of the supporting pipe 1. The inner wall of the sliding circular groove plate 511 is slidably connected to the side wall of the connecting shaft 502. When the rotating shaft 201 rotates, the rotating shaft 201 drives the rotating rod 501 to rotate, thereby causing the connecting shaft 502 to rotate. The gear 505 on the connecting shaft 502 moves on the teeth 506. During the movement, the connecting shaft 502 can rotate, and the crushing rod 503 on the connecting shaft 502 can rotate. The crushing rod 503 rotates to break the crushed rock and make the rock flat. At the same time, when the rotating rod 501 rotates, the rotating rod 501 drives the rotating plate 509 to rotate. The rotating plate 509 drives the arc-shaped push plate 510 to rotate, thereby pushing the crushed rock away from the inside of the supporting pipe 1. When the arc-shaped push plate 510 rotates, it can grind the rock to make it flat.

[0054] During use, the equipment is moved to the required position. To accommodate frequent crushing in multiple locations, the support frame 101 and connecting sleeve 102 support the servo motor 103, thereby increasing the overall stability of the equipment during operation and reducing the shaking generated by the servo motor 103 during operation, facilitating subsequent crushing. The servo motor 103 rotates, driving the rotating shaft 201 to rotate, which in turn drives the inclined circular plate 401 to rotate, causing the inclined circular plate 401 to slide on the extrusion groove 403. During the sliding process, the extrusion rod 402 descends. The extrusion rod 402 slides on the limiting slide rod 405 through the moving slide 404. The limiting support plate 406 supports the limiting slide rod 405, allowing the extrusion rod 402 to generate a downward force to drive the crushing drill bit 40. 7. The rock is crushed. When the rotating shaft 201 rotates, it drives the rotating rod 501 to rotate, which in turn drives the connecting shaft 502 to rotate. The gear 505 on the connecting shaft 502 moves on the teeth 506. During the movement, the connecting shaft 502 rotates, and the crushing rod 503 on the connecting shaft 502 rotates. The crushing rod 503 crushes the rock and flattens it. At the same time, when the rotating rod 501 rotates, it drives the rotating plate 509 to rotate. The rotating plate 509 drives the arc-shaped push plate 510 to rotate, which pushes the crushed rock away from the inside of the support pipe 1. When the arc-shaped push plate 510 rotates, it can grind the rock to make it flat.

[0055] Meanwhile, during the crushing process, dust and broken rocks are scattered in the water, causing rock fragments to remain inside the steel pipe pile, hindering the subsequent pouring of concrete. The rotating shaft 201 drives the spiral plate 202 to rotate, thereby sucking the rock fragments scattered in the water into the support pipe 1. Water enters from the outside of the rotating cylinder 204 through the dust baffle 207, and the screening hole 205 filters the water. The filtered rock fragments are concentrated between the moving circular plate 305 and the support pipe 1. The rotating rod 203 rotates, driving the connecting scraper 206 to scrape the inner wall of the support pipe 1, thereby causing the internal fragments to be discharged from the top of the support pipe 1. During crushing, the return spring 304 drives the second support circular block 303 to move inward, thereby allowing the moving circular plate 305 to fit against the rotating cylinder 204. The moving circular plate 305 blocks the screening hole 205 on the rotating cylinder 204, facilitating the pouring of concrete.
