[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model provides a fillerless biaxial multidimensional vibratory compaction device for dredged sandy soil foundations, such as... Figure 1-4 As shown, the biaxial multidimensional vibratory compaction device for dredged sandy soil foundation includes: a mounting frame 1; vibratory rods 2 symmetrically arranged on the mounting frame 1; a vibratory head 3 arranged on the vibratory rods 2, the vibratory head 3 being used to perform vibratory compaction on the dredged sandy soil foundation; and an exhaust mechanism assembled on the vibratory rods 2, the exhaust mechanism being used to exhaust air when the sand liquefies.

[0022] In this embodiment, the vibratory head 3 uses a 316L stainless steel shell and has a built-in double eccentric block differential frequency vibrator (vertical 30Hz / horizontal 8Hz). The vibratory head 3 is equipped with a salinity sensor and a pH probe. The data monitored by the salinity sensor and pH probe are transmitted to the ground control console via a waterproof cable. When vibrating the filled sand foundation, the mounting frame 1 is connected to the corresponding crawler crane. The crawler crane lifts the vibratory rod 2 and the vibratory head 3. By inserting the vibratory rod 2 and the vibratory head 3 into the filled sand foundation, the filled sand is vibrated. During the vibratory compaction process, the liquefied sand can be vented in real time through the exhaust mechanism. Through the vibratory compaction operation, the relative density of the filled sand can be increased from 55% to over 72%. The overall structure adopts a corrosion-resistant structural design, which extends the service life of the device by three times in coastal environments with a chloride ion content >5%. Compared with traditional single-axis vibratory compaction equipment, it effectively improves the overall vibratory compaction efficiency.

[0023] In a further preferred embodiment of the present invention, the exhaust mechanism includes: an air compressor 4 mounted on one side of the vibrating rod 2; two connecting pipes 5 disposed on the air compressor 4, the two connecting pipes 5 respectively communicating with the central channels on the two vibrating rods 2, and the spiral exhaust hole on the vibrating rod 2 communicating with the central channels.

[0024] In this embodiment, when vibratory compaction is performed, the air compressor 4 is started. The cooperation between the spiral exhaust hole and the central channel on the connecting pipe 5 and the vibrating rod 2 enables timely and effective exhaust when the sand liquefies, preventing the accumulation of gas from affecting the vibratory compaction effect. This further improves the vibratory compaction quality and efficiency of the dredged sand foundation. At the same time, the design of the spiral exhaust hole also helps to increase the exhaust area and improve the exhaust efficiency.

[0025] In a further preferred embodiment of this utility model, the air compressor 4 includes an intake pipe 6, which is disposed on the air compressor 4. A filter box 7 is disposed on the intake pipe 6, and a plurality of filter screens 8 are disposed inside the filter box 7. The filter screens 8 are used to filter impurities in the air drawn into the air compressor 4. A cleaning mechanism is disposed between the filter box 7 and the plurality of filter screens 8, which is used to clean the dust filtered on the filter screens 8.

[0026] In this embodiment, when the air compressor 4 is in use, by setting up the filter box 7 and the filter screen 8, impurities in the air entering the air compressor 4 are effectively filtered, protecting the normal operation of the air compressor 4 and extending its service life. At the same time, the cleaning mechanism ensures that the filter screen 8 can be kept clean, ensuring the durability of the filtration effect and further improving the operating efficiency and reliability of the entire exhaust mechanism.

[0027] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a mounting shaft 9 rotatably mounted on a plurality of filter screens 8; a plurality of cleaning brushes 10 fixedly mounted on the mounting shaft 9, wherein the plurality of cleaning brushes 10 respectively contact both sides of the plurality of filter screens 8; and a driving mechanism assembled between the filter box 7 and the mounting shaft 9, wherein the driving mechanism is used to drive the plurality of cleaning brushes 10 to rotate.

[0028] In this embodiment, when it is necessary to clean the impurities adhering to the filter screen 8, the two control valves on the air inlet pipe 6 are closed. The two control valves are located on both sides of the filter box 7, respectively. The drive mechanism drives the mounting shaft 9 and the cleaning brush 10 to rotate, thereby realizing the automatic cleaning of dust on the filter screen 8 and ensuring the cleanliness and filtration performance of the filter screen 8.

[0029] In a further preferred embodiment of the present invention, the driving mechanism includes: a servo motor 11 fixedly installed on the outer wall of one side of the filter box 7; a connecting shaft 12 rotatably installed on the filter box 7, wherein the output shaft of the servo motor 11 is connected to one end of the connecting shaft 12 through a coupling, and both the connecting shaft 12 and the mounting shaft 9 are fixedly fitted with bevel gears 13, and the two bevel gears 13 mesh with each other.

[0030] In this embodiment, when using the drive mechanism, the servo motor 11 is started by the controller to drive the connecting shaft 12 to rotate. When the servo motor 11 drives the connecting shaft 12 to rotate, the mounting shaft 9 will also rotate due to the meshing action of the bevel gear 13, thereby driving the cleaning brush 10 to clean the filter screen 8, ensuring the cleanliness and filtration performance of the filter screen 8.

[0031] In a further preferred embodiment of this utility model, the filter box 7 is provided with a cleaning mechanism, which is used to clean the dust removed from the filter screen 8 by the cleaning brush 10. The cleaning mechanism includes: a horizontal pipe 14 fixedly installed on one side of the outer wall of the filter box 7; a plurality of collection pipes 15 fixedly installed on the filter box 7, all of which are connected to the horizontal pipe 14 and are respectively located on both sides of the filter screen 8; a discharge cover 16 fixedly installed on the filter box 7, with a bent pipe 17 connected to the discharge cover 16 and connected to the horizontal pipe 14; and a diversion mechanism assembled between the discharge cover 16 and the connecting shaft 12, which is used to divert the cleaned dust to the outside of the filter box 7.

[0032] In this embodiment, when the cleaning brush 10 cleans the dust filtered on the filter screen 8, the rotation of the connecting shaft 12 will activate the diversion mechanism. The diversion mechanism creates a negative pressure inside the discharge hood 16. The dust cleaned by the cleaning brush 10 from the filter screen 8 is discharged from the filter box 7 through the cooperation of the collection pipe 15, the horizontal pipe 14, the discharge hood 16, and the bent pipe 17. This realizes the automatic collection and discharge of the dust cleaned by the cleaning brush 10 from the filter screen 8, thereby preventing dust from accumulating in the filter box 7. When cleaning the filter screen 8, the control valve on the bent pipe 17 needs to be opened. When cleaning is not required, the control valve on the bent pipe 17 needs to be closed.

[0033] In a further preferred embodiment of the present invention, the flow guiding mechanism includes: a rotating shaft 18 rotatably mounted on the discharge hood 16, a plurality of fan blades 19 fixedly mounted on the rotating shaft 18, the plurality of fan blades 19 being located inside the discharge hood 16; two synchronous pulleys 20 respectively fixedly sleeved on the rotating shaft 18 and the connecting shaft 12, and a synchronous belt 21 sleeved on the two synchronous pulleys 20.

[0034] In this embodiment, the power transmission between the connecting shaft 12 and the rotating shaft 18 is realized through the cooperation of the synchronous pulley 20 and the synchronous belt 21. When the connecting shaft 12 rotates, the synchronous belt 21 will drive the synchronous pulley 20 and the rotating shaft 18 to rotate together, thereby driving the fan blade 19 to rotate. The rotating fan blade 19 generates airflow to draw dust out from the filter box 7.

[0035] In a further preferred embodiment of the present invention, a sling 22 is provided on the mounting frame 1, and the sling 22 is used to sling the vibrating rod 2 and the vibrating head 3.

[0036] In this embodiment, the mounting frame 1 and the corresponding crawler crane are easily connected by the lifting rope 22, thereby facilitating the lifting operation of the vibrating rod 2 and the vibrating head 3.

[0037] In summary, compared with related technologies, this device enables unfilled dual-station vibratory compaction of dredged sandy soil foundations, effectively improving the overall efficiency of vibratory compaction operations.

[0038] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
