[0007] In the aforementioned more robust surface pontoon structure, the first connecting part is provided with several limiting blocks, which are arranged around the outside of the external threaded hole. The second connecting part is provided with corresponding limiting grooves, and the limiting blocks can be inserted into the limiting grooves of adjacent pontoons. During the connection of the two pontoons, the limiting blocks are first inserted into the limiting grooves on the other side, and the internal and external threaded holes on the first connecting part will align with the internal and external threaded holes on the second connecting part, facilitating the insertion of bolts for fixing and improving installation convenience. At the same time, the limiting blocks can also distribute the impact force on the bolts, making the connection structure more robust.
[0008] In the aforementioned more robust surface pontoon structure, the first connecting part has an inwardly recessed groove, with the internal and external threaded holes located inside the groove.

The external threaded holes 5 are arranged around the outside of the internal threaded holes 4. The first connecting portion 2 has an inwardly recessed groove 2a. The internal threaded holes 4 and external threaded holes 5 are located inside the groove 2a. An upwardly protruding annular block 2b is located inside the groove 2a, between the internal threaded holes 4 and the external threaded holes 5. The first connecting portion 2 has several limiting blocks 2c, which are arranged around the outside of the groove 2a.
