Description

Technical Field

[0001] This invention relates to the field of silt layer injection technology, specifically to a fluidized silt layer borehole injection structure. Background Technology

[0002] Drilled cast-in-place piles are formed by directly drilling holes at the pile location using machinery or manual methods, then placing reinforcing steel bars inside the holes and pouring concrete. Compared to precast piles, cast-in-place piles have advantages such as being unaffected by changes in geological strata, not requiring splicing or cutting, strong adaptability, and relatively stable stress distribution. Because they do not have the negative effect of soil displacement, and have the ability to penetrate various hard interlayers, embedded rocks, and enter various hard bearing layers, and because of their advantages such as a large range of adjustable geometric dimensions and single pile bearing capacity, cast-in-place piles are widely used as pile foundations for high-rise and important buildings both domestically and internationally.

[0003] During the drilling and grouting process, the grouting guide pipe needs to be sent into the borehole first. Since the grouting guide pipe is composed of multiple connected sections, it needs to be fixed during insertion before connecting to the next stage of the guide pipe. Existing guide pipes come in various sizes, but the opening size of the equipment used to fix them is fixed, making it impossible to adjust the clamping hole diameter according to different sized grouting guide pipes. Furthermore, the fixing equipment only relies on the protrusion at the guide pipe connection port for fixation, resulting in poor connection stability. Additionally, because the borehole and guide pipe diameters are different, issues arise during the drilling process... The gap period after the conduit is installed cannot seal the open window between the conduit and the borehole, making it easy for people, animals, or other equipment and debris to fall into the conduit and borehole during the gap period, thus affecting the grouting. In addition, the existing grouting process for pile grouting conduits only connects the hopper to the conduit and then directly grouts. This method is not only prone to blockage due to air pressure, but also causes the gas to be forced out after the grouting slurry enters the conduit, resulting in the splashing of the grouting slurry, which is inconvenient to use. Based on the shortcomings of the existing technology, this invention designs a fluidized silt layer borehole grouting structure. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. This fluidized mud layer drilling and grouting structure involves starting a drive motor to rotate a threaded rod, causing a sliding sleeve to move towards the drive motor under the control of the threaded rod. The moving sliding sleeve pulls a rotating frame clockwise via a traction plate. The rotating frame, through a crankshaft, pulls a clamping blade, which rotates and gradually unfolds under the limitation of a limiting groove and a second limiting post. At this time, the grouting guide pipe is lifted, moved to the top plate, and placed vertically downwards. It passes through the through groove and enters the borehole. When the top of the grouting guide pipe moves down to the protective cover, the drive motor controls the threaded rod to flip. The flipped sliding sleeve, through the traction plate, pulls the rotating frame counterclockwise. The counterclockwise rotating crankshaft pushes the clamping blade to gradually reset under the limitation of a limiting groove and a second limiting post. The reset clamping blade clamps the top of the grouting guide pipe through stepped clamping teeth. At this time, the lifting of the grouting guide pipe is released, and the top protrusion of the grouting guide pipe engages with the stepped groove of the stepped clamping teeth to complete the clamping and fixing. This device is convenient for clamping and fixing grouting guide pipes of different sizes.

[0018] 2. This type of fluidized silt layer drilling and grouting structure has a cover plate in contact with the upper surface of the base plate in its initial state. A clamping mechanism and a borehole are provided below the cover plate to protect it. At this time, two second telescopic cylinders are activated simultaneously. The second telescopic cylinders extend and push the push arm to rotate under the limitation of the second fixed plate. The rotating push arm drives the cover plate to move backward through the second connecting plate. Since the cover plate is also connected to the first connecting plate, and the first connecting plate is connected to the first fixed plate through the support arm, the push arm drives the cover plate to move backward. At the same time, the cover plate gradually opens by moving backward in an arc shape under the limitation of the first connecting plate, the support arm, and the first fixed plate, so that the clamping mechanism and the borehole are exposed for subsequent installation of the grouting pipe and grouting operation.

[0019] 3. This fluidized mud layer drilling and grouting structure involves moving the feeding hopper above the grouting pipe, and the first telescopic cylinder controlling the feeding mechanism to move downwards, connecting the feeding pipe to the top port of the grouting pipe. At this time, external concrete is fed into the inside of the feeding hopper through the inlet. After starting the drive motor, the rotating shaft is driven to rotate. Since the surface of the rotating shaft is equipped with a scraper, the inner wall of the feeding hopper can be scraped during the concrete grouting process. A feeding wheel is installed in the inner cavity of the feeding pipe and fixed on the rotating shaft, which facilitates the uniform feeding of concrete into the grouting pipe, preventing excessive grouting material from causing blockage, and effectively preventing the grouting material from forcing out air in the borehole and grouting pipe during the grouting process, thus preventing grouting material from splashing.

A threaded rod 602 is threadedly connected inside the sliding sleeve 601. A drive motor 603 is provided at one end of the threaded rod 602. A fixed ladder block 604 is fixedly connected to the surface of the drive motor 603.

[0041] By setting up the traction plate 6, the sliding sleeve 601 and the threaded rod 602, it is easy to drive the rotating frame 505 to rotate, so that it can drive the clamping leaf 508 to open and close.

[0042] Working principle: In the initial state of a fluidized mud layer drilling and grouting structure, a slide 2 is provided on the lower surface of the top plate 102. A sliding block 201 within the slide 2 is connected to a first telescopic cylinder 202. The first telescopic cylinder 202 is connected to the feeding mechanism 3 via a connecting block 203, an arc rod 204, and a fixing block 205, thus supporting the feeding mechanism 3 while simultaneously moving its position. A support frame 101 and a reinforcing rod 103 are provided below the top plate 102 to support the feeding mechanism 3. A scraper 305 and a... are provided inside the feeding hopper 301. The feeding wheel 306 facilitates anti-clogging feeding and scrapes off the mortar remaining on the inner wall of the feeding hopper 301. A rotating frame 505 is rotatably connected inside the clamping seat 501 and protective cover 511 on the upper surface of the base plate 1. The rotating frame 505 is connected to the clamping blade 508 through the crankshaft 507, which facilitates clamping of grouting pipes of different sizes. A cover plate 401 is provided above the clamping mechanism 5. The cover plate 401 is pulled and supported by the support arm 403 and the pushing crank arm 406, which facilitates the opening and closing of the cover plate 401 to protect the borehole and grouting pipe.

[0043] When clamping and fixing grouting guide pipes of different sizes are required, the feeding mechanism 3 is first moved backward under the traction and drive of the slide rail 2, the slider 201 and the first telescopic cylinder 202. Then, the drive motor 603 is started to drive the threaded rod 602 to rotate, so that the sliding sleeve 601 moves in the direction of the drive motor 603 under the control of the threaded rod 602. The moving sliding sleeve 601 pulls the rotating frame 505 to rotate clockwise through the traction plate 6. The rotating frame 505 pulls the clamping blade 508 through the crankshaft 507 and rotates and gradually unfolds under the limitation of the limiting groove 509 and the second limiting post 504. At this time, the grouting guide pipe is lifted and moved to the top plate 102 and then placed vertically downward. After passing through the through groove 502, the pipe enters the borehole. When the top of the grouting pipe moves down to the protective cover 511, the drive motor 603 controls the threaded rod 602 to flip. The flipped sliding sleeve 601 pulls the rotating frame 505 to rotate counterclockwise through the traction plate 6. The counterclockwise rotating crankshaft 507 pushes the clamping leaf 508 to gradually reset under the limit of the limiting groove 509 and the second limiting post 504. The reset clamping leaf 508 clamps the top of the grouting pipe through the stepped clamping teeth 510. At this time, the lifting of the grouting pipe is released, and the top protrusion of the grouting pipe is engaged into the stepped groove of the stepped clamping teeth 510 to complete the clamping and fixing. This device is convenient for clamping and fixing grouting pipes of different sizes.

[0044] When it is necessary to protect and open the clamping mechanism 5 and the drill hole, the cover plate 401 first contacts the upper surface of the base plate 1, which is the initial state. The clamping mechanism 5 and the drill hole are set below the cover plate 401 to protect it. At this time, the two second telescopic cylinders 409 are activated simultaneously. The second telescopic cylinders 409 extend and push the push arm 406 to rotate under the limit of the second fixed plate 405. The rotating push arm 406 drives the cover plate 401 to move backward through the second connecting plate 407. Since the cover plate 401 is also connected to the first connecting plate 402, and the first connecting plate 402 is connected to the second connecting plate 402 through the support arm 403, the first connecting plate 402 is connected to the second connecting plate 402 through the support arm 403. A fixed plate 404 is connected, so that while the push arm 406 moves the cover plate 401 backward, the cover plate 401 gradually opens in an arc shape under the limitation of the first connecting plate 402, the support arm 403 and the first fixed plate 404, so that the clamping mechanism 5 and the borehole are exposed for subsequent installation of the grouting pipe and grouting operation. After the cover plate 401 is unfolded, the second telescopic cylinder 409 retracts and pulls the push arm 406 to rotate. Pushing the push arm 406 to pull the cover plate 401 to reset completes the covering and protection of the clamping mechanism 5 and the borehole. This device is convenient for protecting and opening the clamping mechanism 5 and the borehole.

[0045] When it is necessary to reduce losses and prevent splashing during the grouting process, the feeding hopper 301 is first moved above the grouting pipe. The first telescopic cylinder 202 controls the feeding mechanism 3 to move down, so that the feeding pipe 302 is connected to the top port of the grouting pipe. At this time, the external concrete is fed into the inside of the feeding hopper 301 through the inlet 307. After the drive motor 303 is started, it drives the rotating shaft 304 to rotate. Since the surface of the rotating shaft 304 is provided with a scraper 305, the inner wall of the feeding hopper 301 can be scraped during the concrete grouting process. The feeding wheel 306 is provided in the inner cavity of the feeding pipe 302 and fixed on the rotating shaft 304, which facilitates the uniform feeding of concrete into the grouting pipe, preventing excessive grouting material from causing blockage. It can also effectively prevent the grouting material from forcing out the air in the borehole and grouting pipe during the grouting process, which would cause the grouting material to splash. This device facilitates the reduction of losses and splashing during the grouting process.
