Anti-slip multistage-drop box culvert

Abstract

The invention discloses an anti-slip multistage-drop water box culvert. The anti-slip multistage-drop water box culvert comprises a hollow box culvert body; the outer top and outer bottom of the box culvert body are both in a step shape; a plurality of drop water steps are arranged on the inner bottom face of the box culvert body in a water flow direction; and inclined energy-buffering abrupt slopes are arranged on the step faces of the drop water steps. According to the anti-slip multistage-drop water box culvert of the invention, the outer top and outer bottom of the box culvert body are both arranged to be in a step shape, so that the weight of the box culvert body acts on a soil body below the box culvert body in a vertical direction, meanwhile, covering soil is forwards pressed on thetop of the box culvert body, and the box culvert body and the covering soil on the top of the box culvert body can be effectively prevented from sliding without additional anti-sliding supporting facilities required; water flow is impacted and subjected to energy dissipation through the water drop steps and the energy buffering abrupt slopes in the box culvert body; energy dissipation is furtherconducted on the water flow with energy dissipation protrusions on the upper face of the inner side face of the box culvert body; and water flow speed can be effectively decreased with no additional adopting energy dissipation facilities required.

Description

technical field [0001] The invention belongs to the technical field of box culvert structures, and in particular relates to an anti-slip multi-stage drop box culvert. Background technique [0002] Box culvert refers to a box-shaped hollow culvert whose body is made of reinforced concrete, and the inner space of the box culvert is used to discharge water. Build a new box culvert in a steeper terrain. The steeper slope of the box culvert makes the water flow inside the box culvert faster. In order to reduce the flow velocity of the water body, it is usually necessary to add additional energy dissipation facilities at the entrance or exit of the box culvert to dissipate the water flow. can. At the same time, the soil and rocks on the mountain are easy to loosen during the flood season. In order to prevent the box culvert from slipping, it is necessary to install anti-slip facilities anchored to the mountain at the bottom of the box culvert. [0003] The installation of energy...

AI Technical Summary

Problems solved by technology

[0003] Installing energy dissipation facilities at the outlet of the box culvert and anti-slip facilities at the bottom of the box culvert not only makes the structure of the box culvert more complicated, but also increases the difficulty of the construction of the box culvert

At the same time, since the top of the traditional box culvert is a relatively smooth slope, when the longitudinal slope of the top of the box culvert is steep, it is easy to cause longitudinal slippage of the covering soil on the top of the box culvert, which is not conducive to the safety and stability of the soil on the top of the box culvert and road facilities

[0004] Therefore, in view of the shortcomings of the traditional box culvert that the steep longitudinal slope easily causes the top soil to slip, the water body inside the box culvert cannot effectively dissipate energy when the flow rate of the water body is large, and the box culvert itself is very easy to slip, the present invention discloses an anti-slip multi-stage drop tank culvert
