[0002] During the construction of bored cast-in-place piles on sea riprap dikes, slurry leakage from the hole wall is often encountered. The slurry leakage not only affects the construction quality of the cast-in-place piles, but may also lead to problems such as delays in the construction progress, waste of resources, and pollution of the surrounding environment.

When in use, the second motor 301 is started to drive the screw rod 304 to rotate through the rotating shaft 302. The rotation of the screw rod 304 enables the grout stopping mechanism 3 to slowly and steadily descend. During the descent process, the detector 303 monitors the depth of the bored pile hole, the change of the hole diameter, and whether there is an obvious grout leakage point in real time. The detector 303 transmits the collected data to the control system so that the operator or the automatic system can make corresponding adjustments. When the detector 303 detects When the slurry leakage position is reached, the control system will control the slurry stopping mechanism 3 to continue to descend so that the slurry stopping barrel 305 reaches this position. After the slurry stopping barrel 305 reaches the slurry leakage point, the air bag 309 in the air bag groove 308 is inflated, and the air bag 309 expands, stretching the adjustable sealing sleeve 310 connected to it. The outer surface of the adjustable sealing sleeve 310 fits tightly with the wall of the bored pile hole to form an effective seal to prevent the slurry from continuing to leak. After the sealing is completed, the pre-prepared slurry stopping material is transported into the slurry stopping barrel 305 through the delivery pipe 311, and the nozzle 307 outside the slurry stopping barrel 305 evenly sprays the slurry stopping material onto the slurry leakage position of the bored pile hole wall.

[0021] Furthermore, the spiral rod 304 forms a rotating structure through the second motor 301 and the rotating shaft 302, and multiple groups of connecting rods 306 are arranged on the upper surface of the slurry stopping barrel 305. Through the arrangement of the connecting rods 306, when in use, the multiple groups of connecting rods 306 are evenly distributed above the slurry stopping barrel 305, ensuring the stability of the center of gravity of the slurry stopping barrel 305, so that the slurry stopping barrel 305 remains stable during the lifting and lowering process without tilting or shaking.

[0022] Furthermore, the detector 303 is arranged below the slurry stopping barrel 305, the connecting rod 306 is fixedly connected to the lifting plate 205, and the material of the adjustable sealing sleeve 310 is an elastic material. Through the setting of the adjustable sealing sleeve 310, when in use, the aperture of the bored pile hole may have a certain error or change at different depths. The adjustable sealing sleeve 310 made of elastic material can be adaptively adjusted according to the size of the aperture. When the inflatable bag 309 is inflated, the adjustable sealing sleeve 310 can fit tightly to the hole wall of different diameters, thereby achieving effective sealing.

[0023] Furthermore, multiple groups of nozzles 307 are arranged on the outer surface of the slurry stopping barrel 305, and two upper and lower groups of adjustable sealing sleeves 310 are arranged on the outer surface of the slurry stopping barrel 305.

[0024] Furthermore, the fixing ring 312 is threadedly connected to one side surface of the lifting plate 205 , and two groups of fixing rings 312 are arranged on one side surface of the lifting plate 205 . The two groups of fixing rings 312 fix the delivery pipe 311 from different positions, thereby enhancing the stability of the delivery pipe 311 on the lifting plate 205 .

[0025] Furthermore, the lifting mechanism 2 includes a fixed plate 201, a support rod 202, a first motor 203, a threaded rod 204, a lifting plate 205, a limit block 206 and a limit groove 207. The upper surface of the mobile body 1 is fixedly connected with the fixed plate 201, and the side surface of the fixed plate 201 is fixedly connected with the support rod 202. The upper surface of the fixed plate 201 is fixedly connected with the first motor 203, and the threaded rod 204 is fixedly connected to the end surface of the first motor 203. The outer surface of the threaded rod 204 is threadedly connected with the lifting plate 205. The side surface of the lifting plate 205 is fixedly connected with the limit block 206. The inner surface of the fixed plate 201 is fixedly connected with the support rod 202. A limiting groove 207 is provided on the side surface. Through the arrangement of the fixed plate 201, the support rod 202, the first motor 203, the threaded rod 204, the lifting plate 205, the limiting block 206 and the limiting groove 207, when in use, when it is necessary to adjust the height of the slurry stopping mechanism 3, the first motor 203 is started to drive the threaded rod 204 to rotate. When the threaded rod 204 rotates, according to the principle of thread transmission, the lifting plate 205 moves along the threaded rod 204. During the movement of the lifting plate 205, the limiting block 206 fixedly connected to the one side surface of the lifting plate 205 will slide in the limiting groove 207 provided on the inner surface of the fixed plate 201.

[0026] Furthermore, the other end of the support rod 202 is fixedly connected to the mobile body 1, and two groups of support rods 202 are arranged on one side surface of the fixed plate 201.

Through the arrangement of the fixed plate 201, the support rod 202 and the mobile body 1, when in use, the support rod 202, the fixed plate 201 and the mobile body 1 form a stable triangular supporting structure, and the triangular structure greatly improves the overall stability.

[0028] Furthermore, two groups of limit blocks 206 are symmetrically arranged with respect to the central axis of the lifting plate 205. The limit blocks 206 are slidably connected to the limit grooves 207. The inner dimensions of the limit grooves 207 coincide with the outer dimensions of the limit blocks 206. Through the arrangement of the limit blocks 206, when in use, the two groups of limit blocks 206 limit the lifting plate 205 from both sides of the lifting plate 205, further ensuring the balance and stability of the lifting plate 205, so that the slurry stopping mechanism 3 can smoothly rise or fall to a suitable height position. Example 2

[0029] The construction method of the bored pile quick leakage stopping slurry device on the sea riprap embankment adopts the bored pile quick leakage stopping slurry device on the sea riprap embankment of any one of claims 1 to 9, and further comprises the following steps: Step 1: Move the mobile vehicle body 1 to a suitable location near the bored pile construction site, ensure that the site is flat and the vehicle is parked firmly to avoid displacement during subsequent operations; Step 2: Start the first motor 203 to adjust the height of the grout stopping mechanism 3, and adjust the grout stopping mechanism 3 to a suitable height slightly higher than the hole of the bored pile; Step 3: by using the self-moving function of the mobile body 1, the device is moved to the position just above the hole of the bored pile to be processed, so that the stop grout barrel 305 is aligned with the bored pile hole; Step 4: Adjust the height of the lifting plate 205, start the second motor 301, and slowly lower the grout stopping mechanism 3. The rotation of the screw rod 304 can make the grout stopping mechanism 3 more convenient to lower. The detector 303 monitors the depth and diameter changes of the bored pile hole below and whether there is an obvious grout leakage point in real time, and transmits the data to the control system; Step 5: When the detector 303 detects the leakage position and approaches the wall of the bored pile hole, the stop grout barrel 305 is controlled to descend to the leakage position, and air is inflated into the airbag 309, so that the airbag 309 expands and opens the adjustable sealing sleeve 310 to seal the leakage position; Step 6: After the sealing is completed, the pre-prepared grout-stopping material is delivered to the grout-stopping barrel 305 through the delivery pipe 311, and the nozzle 307 sprays the grout-stopping material to the grout-leaking part of the bored pile hole wall to achieve accurate plugging of the grout-leaking point; Step 7: When it is detected that the slurry leakage phenomenon has been effectively controlled, the second motor 301 is stopped, the material conveying into the slurry stopping barrel 305 is stopped, and the lifting plate 205 is slowly lifted to drive the slurry stopping mechanism 3 to move upward and evacuate the bored pile hole.

[0030] Working principle: When the height of the stop grouting mechanism 3 needs to be adjusted, the first motor 203 is started to drive the threaded rod 204 to rotate. When the threaded rod 204 rotates, according to the principle of thread transmission, the lifting plate 205 moves along the threaded rod 204. During the movement of the lifting plate 205, the limit block 206 fixedly connected to the surface of one side of the lifting plate 205 will slide in the limit groove 207 provided on the inner surface of the fixed plate 201. The second motor 301 is started to drive the screw rod 304 to rotate through the rotating shaft 302. The rotation of the screw rod 304 enables the stop grouting mechanism 3 to descend slowly and steadily. During the descent, the detector 303 monitors the depth and diameter changes in the bored pile hole in real time, and whether there are obvious leakage points and other information. The detector 303 The collected data is transmitted to the control system so that the operator or the automatic system can make corresponding adjustments. When the detector 303 detects the leakage position, the control system will control the slurry stopping mechanism 3 to continue to descend so that the slurry stopping barrel 305 reaches the position. After the slurry stopping barrel 305 reaches the leakage point, the air bag 309 in the air bag groove 308 is inflated. The air bag 309 expands and opens the adjustable sealing sleeve 310 connected to it. The outer surface of the adjustable sealing sleeve 310 fits tightly against the wall of the bored pile hole to form an effective seal to prevent the slurry from continuing to leak. After the sealing is completed, the pre-prepared slurry stopping material is transported into the slurry stopping barrel 305 through the delivery pipe 311, and the nozzle 307 outside the slurry stopping barrel 305 evenly sprays the slurry stopping material onto the leakage part of the bored pile hole wall.

10. A construction method for a quick leakage-stopping slurry device for bored piles on a riprap embankment in a sea area, characterized in that: The device for quickly stopping leakage of bored piles on sea riprap dikes according to any one of claims 1 to 9 further comprises the following steps: Step 1: Move the mobile vehicle (1) to a suitable location near the bored pile construction site, ensure that the site is flat and the vehicle is parked securely to avoid displacement during subsequent operations; Step 2: starting the first motor (203) to adjust the height of the grout-stopping mechanism (3), and adjusting the grout-stopping mechanism (3) to a suitable height slightly higher than the hole of the bored pile; Step 3: by using the self-moving function of the mobile body (1), the device is moved to the position just above the hole of the bored pile to be processed, so that the stopper barrel (305) is aligned with the hole of the bored pile; Step 4: Adjust the height of the lifting plate (205), start the second motor (301), and slowly lower the grout stopping mechanism (3). The rotation of the spiral rod (304) can make the grout stopping mechanism (3) more convenient to lower. The detector (303) monitors the depth and diameter changes of the bored pile hole below and whether there is an obvious grout leakage point in real time, and transmits the data to the control system; Step 5: When the detector (303) detects the leakage position and approaches the wall of the bored pile hole, the grout stopping barrel (305) is controlled to descend to the leakage position, and air is inflated into the air bag (309), so that the air bag (309) expands and opens the adjustable sealing sleeve (310) to seal the leakage position; Step 6: After the sealing is completed, the pre-prepared grout-stopping material is transported into the grout-stopping barrel (305) through the transport pipe (311), and the nozzle (307) sprays the grout-stopping material onto the grout-leaking part of the bored pile hole wall, thereby achieving accurate plugging of the grout-leaking point; Step 7: When it is detected that the slurry leakage phenomenon has been effectively controlled, the second motor (301) is stopped, the material conveying into the slurry stopping barrel (305) is stopped, and the lifting plate (205) is slowly lifted to drive the slurry stopping mechanism (3) to move upward and evacuate the bored pile hole.
