Description

TECHNICAL FIELD

[0001] The utility model water conservancy box culvert technical field, more specifically, it is related to the box culvert for connecting inverted siphon channel. BACKGROUND

[0002] In the huge system of water conservancy projects, inverted siphon, as a key water conveying facility, plays an indispensable role when the channel needs to cross complex terrain and obstacles. When the channel needs to cross terrain conditions such as rivers, roads, valleys, etc., inverted siphon, with its unique working principle, guides water flow to pass smoothly under the obstacle through pressure difference, ensuring the continuity of water conveying. The box culvert for connecting inverted siphon channel, as a core component of inverted siphon structure, undertakes the important responsibility of guiding water flow, maintaining stable and safe water conveying.

[0003] Based on the above, however, the box culvert for connecting inverted siphon channel now usually uses prefabricated box culverts to speed up construction progress. However, the prefabricated box culvert is segmented and needs to be assembled and spliced by a large number of bolts, resulting in a relatively cumbersome process during assembly, affecting the overall construction progress. Moreover, the repetitive tightening action increases the labor intensity of the constructor, which can easily cause fatigue and thus affect the construction quality. INVENTION CONTENTS

[0004] To solve the above technical problems, the present disclosure relates to a box culvert for connecting inverted siphon channel to solve the problem that the box culvert now needs to be assembled and spliced by a large number of bolts, resulting in a relatively cumbersome process during assembly and affecting the overall construction progress.
