It includes two symmetrically arranged dams, with a riverbed base cast in cement between one end of the two dams. A culvert body is fixed between the two dams, and the culvert body includes two support columns (first type). A roadbed is fixed between the top surfaces of the two support columns (first type), and multiple support columns (second type) are fixed at equal intervals in the middle of the roadbed surface. In this invention, a movable and tiltable tray is arranged inside the conventional culvert. The tray rotates inside the culvert to unload collected sediment into a space below the tray. A water-diverting plate is arranged at the culvert's inlet. This plate can move to different positions and tilt, facilitating the interception of water flow into a designated culvert. The high-flow-rate water washes over the tray, improving the efficiency of cleaning sediment from its surface.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy culvert, in particular to a new water conservancy culvert structure with controllable water flow division and combination. BACKGROUND

[0002] The culvert refers to a drainage hole (water passage) built under the roadbed or below the road surface in highway engineering construction to make the highway pass through the water channel smoothly without hindering traffic. Through this structure, water can flow from under the highway. The culvert is often used to discharge flood across natural valleys and depressions, or to cross roads as a vertical traffic passage for people, animals and vehicles, or as a water channel for farmland irrigation.

[0003] Water flow sedimentation is a common problem encountered in the drainage process of the culvert. When there is silt or sediment accumulation in the local area of the culvert opening, it may cause water flow obstruction inside the opening, which not only affects the drainage capacity per unit time of the opening but also causes damage to the structure of the culvert. Therefore, after the culvert is not drained or the upstream gate is closed, the silt deposited inside the culvert opening is cleaned. In order to ensure the cleanliness of the downstream water quality, some culverts are installed with grilles at the water outlet of the culvert. If the garbage intercepted by the grilles is not timely treated, it will also block the culvert.

[0004] Therefore, it is necessary to design a new water conservancy culvert structure with controllable water flow division and combination. The culvert structure can automatically detect whether there is sediment accumulation inside the culvert during the drainage process, and can clean the deposited sediment and garbage inside the culvert on the roadbed in time. In addition, the culvert structure can promote the rapid flow of the deposited sediment and garbage by the impact force of the water flow division and combination. SUMMARY
