Description

Technical Field

[0001] The present invention relates to the technical field of underwater tunnel construction monitoring, and particularly relates to a method for checking the attitude of a leveling hull in a fully floating state. Background Art

[0002] When leveling the crushed stone bed of an underwater immersed tunnel, it is necessary to conduct a checking operation on the leveling barge. Currently, the original checking method for the leveling barge is to conduct the check in the state of inserting piles in cooperation with an attitude instrument. However, for some underwater tunnels with special geological conditions (such as the Dalian Bay underwater tunnel), there are risks in pile insertion, and full-floating leveling construction is adopted. Due to the high precision requirements for the leveling of the underwater tunnel bed, the hull will tilt during the walking of the large and small vehicles of the leveling barge due to position changes and the influence of external wind, waves and currents, affecting the construction accuracy. The method of checking the hull attitude by inserting piles cannot accurately check the instantaneous attitude of the hull during full-floating leveling construction. Summary of the Invention

[0003] The present invention aims to solve the deficiencies of the prior art and provides a method for checking the attitude of a leveling hull in a fully floating state.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for checking the attitude of a leveling hull in a fully floating state, the specific steps are as follows:

[0006] S1. Layout of the checking system

[0007] The checking system includes four checking and monitoring components, four measuring robots, four communication modules, a data processing terminal and a power supply device;

[0008] The four checking and monitoring components are respectively vertically fixed at the four corner points of the leveling barge. The four measuring robots are installed on the land ground, and each measuring robot corresponds to one checking and monitoring component. The four measuring robots are connected to the data processing terminal through four communication modules, and the measuring robots, the data processing terminal and the power supply device are connected;

[0009] S2. Hull attitude checking

[0010] Start the power supply device for power supply, and start the measuring robots and the communication modules; after starting the measuring robots, conduct monitoring and learning, respectively measure the corresponding feature points, and after the learning is completed, enter the tracking mode to monitor the hull attitude, and transmit the data through the communication modules. The data processing terminal takes the average value of the sinking amounts of the four points as the adjustment amount of the hull attitude. After automatically calculating the results, give the adjustment value required by the hull leveling system. Take the elevation of the point with the largest adjustment amount as the reference and subtract the elevations of other points to obtain the height differences of each point, so as to automatically control the hull attitude. After the leveling system reads it, it automatically adjusts the hull attitude.

[0011] In step S1, the checking and monitoring component is a monitoring prism arranged on the leveling ship.

[0012] In step S1, the checking system further includes a backup power supply, which is connected to the measuring robot and the data processing terminal.

[0013] In step S1, a display is provided on the data processing terminal of the checking system.

[0014] In step S2, the formula automatically calculated by the data processing terminal is:

[0015] TH n =(H1 + H2 + H3 + H4) / 4 - H n ;

[0016] TH n : represents the value by which the hull at the leg with code n needs to rise or fall; if the value is negative, it means it needs to fall, and vice versa it needs to rise;

[0017] H n : represents the elevation of the characteristic point of the characteristic area of the hull with code n.

[0018] In step S2, when the power supply device fails, the backup power supply is started to supply power.

[0019] The beneficial effects of the present invention are as follows: The present invention can be applied to the measurement of the hull attitude adjustment during the full floating state of the leveling ship for the subsea immersed tube tunnel. The operator can retrieve and view the freeboard height measurement data for any time period through the system background; when measuring the hull attitude, there is no situation of human observation gross error; it can automatically measure the instantaneous attitude of the leveling ship hull; it can continuously measure the instantaneous attitude of the leveling ship hull.
