The inserted bottom tube 306 is inserted into the topmost corrugated steel tube and then fixed thereto, which may be by welding, bolts or other reliable means.

Referring to fig. 6, in the present embodiment, the fixing manner of the bottom socket 306 and the corrugated steel pipe 501 is bolting of the compression ring 304; the outer wall of the plug-in bottom barrel 306 is fixedly provided with a retainer ring 303, when the plug-in bottom barrel 306 is inserted into the corrugated steel pipe 501, the retainer ring 303 is abutted against the steel pipe flange ring 502 at the top of the corrugated steel pipe 501, a compression ring 304 is further arranged above the retainer ring 303, and the compression ring 304, the retainer ring 303 and the steel pipe flange ring 502 are integrally connected through a plurality of high-strength bolts 7 which penetrate through the compression ring and are circumferentially arranged. The compression ring bolting mode can effectively strengthen the plug bottom barrel 306 and the corrugated steel pipe 501, and prevent the plug bottom barrel 306 from sliding or falling off when being stressed.

In the above-mentioned compression ring bolting structure, bolt connection holes corresponding to positions need to be formed on the compression ring 304, the retainer ring 303 and the steel pipe flange ring 502, and three components are bolted after being stacked, which may cause difficulty in hole alignment. To solve this problem, referring to fig. 7, the retainer ring 303 of the present embodiment is designed in a tooth-shaped structure with notches for passing high-strength bolts. Thus, the compression ring 304 only needs to be aligned with the steel pipe flange ring 502, but does not need to be aligned with the retainer ring 303, so that the difficulty and error of aligning holes are simplified. Meanwhile, the notch of the tooth-shaped structure can also play a role in positioning and preventing loosening, so that the compression ring 304 is prevented from rotating or moving when being stressed.

The reinforcing ribs 305 intersecting with each other are provided on the base 301 to reinforce the strength and rigidity of the base 301, and the reinforcing ribs 304 are made of steel plates.

In practical applications, the aqueduct body may need to withstand large spans and loads, and thus the problem of bending resistance thereof needs to be considered.

One solution is to add stringers to the aqueduct body. The longitudinal beam is a strip-shaped structure formed by steel plates or steel pipes and is connected with the aqueduct body along the water flow direction, so that the effect of reinforcing and supporting is achieved. The stringers may be attached to the aqueduct body by welding, bolts or other reliable means.

The solution has the advantages of effectively improving the bending resistance of the aqueduct body, increasing the rigidity and stability of the aqueduct, and being applicable to the conditions of large span and large load.

Another solution is to add longitudinal ribs in the aqueduct body. The longitudinal ribs are strip-shaped structures formed by steel bars or steel wires and are connected with the inside of the aqueduct body along the water flow direction, so that the functions of reinforcement and support are achieved. The longitudinal ribs may be connected to the aqueduct body by welding, bolts or other reliable means. The number, the positions and the sizes of the longitudinal ribs can be reasonably designed and optimized according to the span and the load of the aqueduct. But this solution may affect the tightness of the interior of the aqueduct and may affect the appearance of the aqueduct and the smoothness of the water flow.
