Technical Field
[0001] This utility model relates to the field of inverted siphon protection technology, and in particular to a protective structure for inverted siphons. Background Technology
[0002] When a channel is at a similar elevation to a road or ditch and they intersect at the same level, a structure is needed to allow water to pass under the road or ditch. This structure is usually called an inverted siphon. Inverted siphon pipes are often made of fiberglass reinforced plastic (FRP) and generally consist of three parts: an inlet, a pipe body, and an outlet. The overall layout should be determined by a comprehensive analysis of factors such as topography, geology, construction, water flow conditions, traffic conditions, and the impact of floods. They are installed in the trench using a socket-insertion method and then fixed with concrete.
[0003] Because inverted siphons are installed in river sections where sand mining occurs, the riverbed topography has changed significantly. The riverbed elevation has dropped considerably over a large area upstream and downstream of the inverted siphons. Water erosion has caused the thickness of the overburden on top of the inverted siphons to gradually decrease, affecting their safety. To reduce erosion caused by sand mining upstream and downstream of the inverted siphons and protect their safety, protective measures are needed. Horizontal lining is usually used as a protective measure, but this is easily damaged, has poor erosion resistance, and the joints of the inverted siphons can loosen after prolonged erosion, affecting their subsequent use.
[0004] Therefore, the existing protective structures for inverted siphons all use horizontal lining, which is prone to damage, has poor impact resistance, and the joints of the inverted siphons become loose after long-term scouring, affecting subsequent use. To address this issue, a new protective structure for inverted siphons can be designed. By installing a protective structure at the joints, the tightness of the joints can be improved, preventing loosening caused by scouring. Utility Model Content
