[0001] The utility model belongs to the technical field of caisson installation, and in particular relates to a caisson transportation, installation, measurement and positioning system. Background Art

[0002] Gravity-type docks are one of the main structural forms of docks, and most gravity-type docks use caisson structures. At present, caisson installation measurements generally use manual measurement of the caisson's position and elevation to provide a reference for caisson installation. During the entire process of the caisson undocking and diving, surveyors need to hold a GPS measuring device on the caisson in real time to repeatedly measure the plane position and elevation around the caisson in real time.

[0028] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0031] See attached Figures 1 to 2 , gives a schematic embodiment of the caisson shipping, installation, measurement and positioning system proposed in the utility model, which includes a cover plate 1, a first GPS positioning device 2, a first liquid level meter 4, a valve 5 and a data processing terminal 6.

[0032] A cover plate 1 is installed over the caisson compartments. In this embodiment, multiple cover plates 1 are provided, equal in number to the number of caisson compartments. A control cabinet 3 is mounted on the cover plate 1. The control cabinet 3 has support legs welded to the cover plate 1, ensuring a more secure connection between the control cabinet 3 and the cover plate 1, preventing the control cabinet 3 from shaking or slipping during the transportation and installation of the caisson 10.

[0033] Two first GPS positioning devices 2 are provided, one located at opposite corners of the top of the caisson 10. The two first GPS positioning devices 2 are connected to the control cabinet 3 via cables 31. A first liquid level gauge 4 is located within the caisson compartment and connected to the control cabinet 3 via cables 31. A valve 5 is located at the water inlet of the caisson compartment. A data processing terminal 6, connected to the control cabinet 3 via cables 31, acquires measurement data from the first GPS positioning devices 2 and the first liquid level gauge 4 and performs calculations.

[0034] To verify the position of the caisson 10 and ensure that the installation accuracy of the caisson 10 meets the requirements, in this embodiment, the caisson shipment installation measurement and positioning system also includes a second GPS positioning device 7. After the caisson 10 is seated, the second GPS positioning device 7 is used to verify the actual position of the caisson 10 and compare it with the system installation deviation to verify the installation quality of the caisson 10.

[0035] In this embodiment, the type of the first GPS positioning device 2 and the second GPS positioning device 7 is RTK GGA. RTK technology combined with the positioning information output by GGA sentences can achieve high-precision positioning, which can improve work efficiency and measurement accuracy.

[0036] Caisson compartments usually have different partitions, and each partition may differ in function, structural characteristics or fluid flow characteristics. In order to achieve independent monitoring of the liquid level of each partition, in this embodiment, multiple first liquid level gauges 4 are provided, and the multiple first liquid level gauges 4 are respectively arranged in the caisson compartments of different partitions.

[0037] The installation of multiple first liquid level gauges 4 comprehensively reflects the overall liquid level within the caisson 10. Although each compartment is relatively independent, they collectively constitute the caisson compartment as a whole. By collecting and analyzing liquid level data from each compartment, the liquid level trend of the caisson 10 can be accurately determined, improving the safety and stability of the caisson and ensuring the normal operation of its internal facilities.

[0038] In order to improve the accuracy of measurement, in this embodiment, the caisson shipment installation measurement and positioning system also includes a second liquid level gauge 8, which is connected to the control cabinet 3 via a cable 31. There are multiple second liquid level gauges 8, and the multiple second liquid level gauges 8 are arranged in different partitions of the caisson compartments in a one-to-one correspondence with the multiple first liquid level gauges 4. The multiple second liquid level gauges 8 are respectively used to verify the measurement data of the corresponding first liquid level gauges 4. By providing the first liquid level gauge 4 and the second liquid level gauge 8, the impact of the error of a single liquid level gauge on the measurement results can be reduced. When there is a difference in the measurement results of the corresponding first liquid level gauge 4 and the second liquid level gauge 8, the error can be reduced by averaging, weighted averaging, etc.

[0039] To monitor the tilt angle of the caisson 10 in real time, in this embodiment, the caisson shipment, installation, measurement, and positioning system further includes an inclinometer 9, which is mounted on the control cabinet 3 and connected to the control cabinet 3 via a cable 31. The inclinometer 9 continuously monitors the tilt of the caisson 10 during installation, providing precise guidance for installation operations and ensuring that the installation quality of the caisson 10 meets the requirements of the engineering design and specifications, thereby avoiding subsequent engineering quality issues caused by excessive tilt.

[0040] In order to protect the control cabinet 3 and other equipment installed on the caisson 10, in this embodiment, the caisson shipment installation measurement and positioning system also includes a canvas cover, which is detachably installed on the caisson 10. After each device is installed in place, the canvas cover is installed on the caisson 10 to provide effective physical protection for each device and extend its service life.

[0041] To enable real-time visual monitoring of the shipping and installation process of the caisson 10, in this embodiment, the data processing terminal 6 includes a display screen 61 for displaying calculation results and the installation status of the caisson 10. The provision of the display screen 61 helps workers understand the installation status of the caisson 10 in real time, making timely adaptive adjustments to ensure smooth installation and improve installation efficiency.

[0042] In the above-described exemplary embodiment, the caisson shipment and installation measurement and positioning system can accurately measure the caisson's position and posture in real time, improving caisson installation efficiency. The system includes a second GPS positioning device and a second liquid level gauge for verifying and rechecking measurement data, enhancing measurement accuracy and system reliability.

[0043] The following is combined with Figures 1 to 2 The working process of an embodiment of the caisson transport, installation, measurement and positioning system of the present invention is described as follows:

[0044] The control cabinet 10 and other equipment are installed on the cover plate 1. The cover plate 1 is then hoisted to the designed position on top of the caisson 10 using a gantry crane in the prefabrication yard. The first GPS positioning device 2 is then installed to measure the initial position of the caisson 10. This data is transmitted via cable 31 to the data processing terminal 6. The data processing terminal 6 then inputs various parameters and the construction base map. After debugging of each device is complete, the power is disconnected and each device is covered with a canvas cover. Before shipping the caisson 10, the power is connected, the canvas cover is opened, and all equipment is verified to be operating normally. The caisson 10 is then ready for shipment.

[0045] The planned caisson installation route map is imported into the caisson positioning software and viewed on display screen 61. After undocking, the caisson 10 is towed along the route map to the designed location by a positioning barge. During this process, the commander can make timely adjustments to the caisson position based on the display screen 61 to prevent the caisson from running aground.

[0046] After the caisson 10 reaches the designed position, the valve 5 is opened and water is added to start diving. The four-corner deviation value and elevation of the plane position of the caisson 10 are viewed in real time on the display screen 61. The position of the caisson 10 is continuously adjusted during the diving process. The display screen 61 shows the distance between the caisson and the bottom. The commander adjusts the water addition rate accordingly until the caisson 10 lands on the bottom.

[0047] After the caisson 10 is seated, the second GPS positioning device 7 is used to verify the actual position of the caisson 10 and compare it with the system installation deviation to verify the installation quality of the caisson 10.

[0048] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
