Without loss of generality, the sleeve shown in the drawing is taken as a description main body in the embodiment, and the leveling scheme of the underwater guiding and positioning device for the driven pile is explained in detail. It should be understood that the sleeve can be selected as desired, its own structure and its adaptation to the driven pile are not the core points of the present application, and do not constitute a substantial limitation on the positioning device claimed in the present application.
Referring to fig. 1 and 2, fig. 1 is a front view of an embodiment of an underwater pile sinking guiding and positioning device, and fig. 2 is a top view of fig. 1.
The underwater pile sinking guiding and positioning device comprises four sleeves 1 which are fixedly connected through positioning frames 2. Here, the number of the sleeves 1 is adapted to the number of the driven piles of the specific engineering design, and may be three or more than three; that is, at least three sleeves 1 can meet the basic requirement of overall leveling reliability.

Wherein, this prevent sinking board 3 is located the below of corresponding sleeve 1, forms the holding surface based on each sleeve 1 and seabed surface, and as shown in the figure, this prevent sinking board 3's face is greater than the bottom surface of sleeve 1 to compromise two functional needs of support and anti-sinking. It can be understood that, based on the sinking column construction process, for the anti-sinking plate 3 located right below the sleeve 1, the middle part of the plate body should be provided with a matched process opening.
At least three telescopic struts 4 are provided for each sleeve 1 to provide a levelling support force in the circumferential direction, respectively. For example, but not limited to, four telescopic struts 4 are provided for each sleeve 1, and are circumferentially spaced relative to the respective sleeve 1, preferably, the telescopic struts 4 are circumferentially spaced at an optimum spacing to maximize the balance of the circumferential support forces.
As shown in the figure, two ends of each telescopic stay bar 4 are respectively hinged with an anti-sinking plate 3 and a sleeve 1, so that when the anti-sinking plate 3 is inclined after contacting with the surface of the seabed based on the characteristics of different foundation bearing capacities and different compression moduli of soil bodies below the sleeve 1 in the sinking process of the positioning device, the corresponding telescopic stay bars 4 can be respectively utilized to realize adaptive adjustment, and therefore, the levelness of the positioning device is adjusted by changing the length of the stay bars, so that multi-point independent leveling processing is realized based on different characteristics of surface soil of the seabed, and the integral leveling capability is greatly improved; on the basis of ensuring the leveling precision, a good technical guarantee is provided for improving the whole application range, and the device can be applied to sea areas with different geological conditions and has a wide application range. The construction precision is high, and the cost is controllable.
It should be noted that the telescopic stay bar 4 can select structures with different length adjustment principles according to needs; for example, but not limited to, the telescopic stay 4 is a hydraulic control stay, and the length of the telescopic stay can be adjusted based on the pressure formed by the actual load by using a liquid as a working medium, which is internally arranged in the structure. It can be understood that the working principle of the hydraulic stay bar is not the core invention point of the present application, and therefore, the detailed description is omitted.
In fact, the telescopic stay 4 can also be in the form of a stay using gas as working medium, provided that the functional requirements of the length adjustment are met within the scope of the present application.
In order to improve the overall levelling ability of the positioning device, a buoy 5 may preferably be added in correspondence with each sleeve 1. As shown, each pontoon 5 is fixed to the outside of the respective sleeve 1, whereby height adjustment at the location of the respective sleeve 1 is achieved by a respective buoyancy force built up by a change in the internal water storage. The pontoons 5 have water connections 51 to regulate the water storage in the respective pontoon 5 via the water connections 51. Therefore, when the inclination of the positioning device is larger and the adjusting range of the telescopic stay bar 4 cannot meet the leveling requirement, the buoy 5 is used for synchronous regulation and control.

The buoyancy provided by the buoy 5 is utilized to reduce the pressure of the anti-sinking plate 3 on the sea bed surface, and the integral leveling capability is further improved.
Here, the configuration of the pumping unit 81 may be selected according to the system pumping circuit design. For example, but not limited to, a plurality of pumping units 81 are provided, each of which is configured to communicate with each of the pontoons 5, and in this configuration, when the water storage capacity of any one of the pontoons 5 needs to be adjusted, the pumping unit 81 corresponding thereto is activated.

Based on the control strategy, the control unit 82 is adapted to output a water volume adjustment command to the control side of the pumping unit 81 and/or the valve unit to adjust the water storage volume in the buoy 5 based on the level status information. During actual pile sinking operation, the water quantity in the buoy 5 is adjusted according to actual conditions, so that the levelness of the positioning device is accurately adjusted, and the device has the characteristics of simplicity in operation, high efficiency and better reliability.
In addition, the pipe end of the water pipe 6 extends into the bottom of the corresponding buoy 5, and a measuring instrument 84 capable of collecting the water amount in the buoy 5 is arranged at the pipe end; thus, the control unit 82 can output a water amount adjustment command to the control end of the pumping unit 81 and/or the valve unit according to the level state information acquired by the signal acquisition unit 83 and the water amount measured by the measuring instrument 84. Therefore, different real-time data information which is actually collected is integrated, and overall regulation and control are carried out.
In the scheme, wireless data communication is preferably adopted between the signal acquisition unit 83 and the control unit 82, so that system configuration is facilitated, and operability is higher.

In contrast, the lifting lugs 12 are disposed on the sleeves 1, so that the load borne by the positioning frame 2 in a lifting state can be reasonably controlled.
