Description

TECHNICAL FIELD

[0001] The utility model relates to the field of side slope drainage, in particular to a multi-step high side slope chute device. BACKGROUND

[0002] The side slope chute is a structure arranged on the side slope, which mainly functions to collect and discharge the torrent generated during rainfall or snowmelt, slow down the speed, prevent the water flow from scouring and eroding the surface of the side slope, maintain the integrity and stability of the side slope soil, thereby prolonging the service life of the side slope and reducing the adverse effects of soil loss on the surrounding environment. The side slope chute has important significance in engineering practice and environmental management. In order to improve the side slope drainage efficiency and minimize the impact of water flow on the side slope, domestic scholars have carried out a large number of researches and designs on the structure type of the chute.

[0003] Chinese patent CN202022398115.4 proposes a side slope chute, which reduces the impact damage of water flow on the side slope bottom by adding a stilling ridge and a buffer groove in the structure.

[0004] Chinese patent CN202121883272.2 proposes a chute structure for the soil excavation side slope of highway in tropical regions, which reduces the flow velocity of water flow and the content of silt carried by water flow when entering the side ditch by combining filter screen, sand trap and water collecting chamber.

[0005] However, the chute structures in the above two patents are complex, and it is difficult to construct in relatively steep high side slopes, and there are defects such as large space occupation at the lower part.

[0006] Chinese patent CN202121736038.7 proposes a hidden side slope chute structure, which drains through the inclined pipe buried in the slope body, thereby playing the roles of splash prevention and improving the landscape effect of the side slope. However, considering that the side slope water flow carries a lot of silt, the structure is difficult to carry out dredging and maintenance work due to its concealment, and the size of the pipeline is fixed, which limits its drainage function.

[0007] In summary, the existing design method of side slope chute mainly reduces the impact damage of water flow by setting stilling ridges in the drainage path and setting buffer ditches at the lower part of the side slope, and reduces the influence of silt by setting filter screens and sand traps. These designs are mainly used for side slopes with small slope, and are not suitable for steep multi-step high side slopes. At the same time, the lower space is large, and there may be problems such as boundary invasion. UTILITY MODEL CONTENTS
