Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a highway roadbed slope anti-skid device. Background Art

[0002] The roadbed slope is usually built in a single slope, broken line and stepped shape, and is built according to the height of the slope to meet different design requirements. In order to prevent the slope from sliding, a protective plate is usually laid on the slope to prevent the slope from sliding under the impact of heavy rain. The protective plate is usually a hollow structure, and green plants can be planted in the hollow position. The green plants not only play a role in greening, but also play a role in preventing slipping. The thickness of the commonly used protective plates is not enough to penetrate deep into the soil. The protective plates are mostly made of plastic, and the protective plates are prone to aging, which makes the roadbed slope easy to slide. There are many reasons for the slope to slide. The slope is too steep, and it is easy to slide when it encounters heavy rain. In addition, most slopes are not reinforced, and the soil is relatively loose. When it encounters heavy rain, the soil is easy to collapse, which leads to the slope sliding. In response to the above problems, we invented a highway roadbed slope anti-skid device.

[0003] The utility model provides a highway roadbed slope anti-skid device which solves the above technical problems.

[0004] The technical solution of the utility model is achieved as follows: a highway roadbed slope anti-skid device comprises a top beam pre-buried at the top of the slope, a bottom beam pre-buried at the root of the slope, and a plurality of drainage grooves laid on the slope surface; the top beam is provided with a plurality of water outlets along the side surface, the bottom beam is provided with a plurality of drainage outlets along the side surface, and the two ends of the drainage groove are respectively connected to the water outlet and the drainage outlet; a plurality of support frames are also laid on the slope surface, the support frames are arch-shaped, the two ends of the support frames are in contact with the bottom beam, the support frames and the drainage grooves are alternately distributed, the support frames are provided with a plurality of partition plates extending upward along the top surface, and the top end of the partition plates is in contact with the top beam; the top beam, the bottom beam and the drainage grooves are all precast concrete components.

[0005] Furthermore, the support frame is a cast-in-place concrete component, and support feet are provided at both ends of the support frame; a plurality of support seats are provided along the inner side of the bottom beam, and steel bars are preset on the support seats, and the support feet are in contact with the support seats, and the steel bars are passed through the support feet.

[0006] Furthermore, the support frame is provided with a plurality of first water filtering holes, and the partition plate is provided with a plurality of second water filtering holes.

[0007] Furthermore, the cross-section of the top beam is a horizontal "T"-shaped structure, the lower half of the top beam is pre-buried in the slope soil, and the water outlet is opened in the upper half of the top beam; the cross-section of the bottom beam is a horizontal "L"-shaped structure, the lower half of the bottom beam is pre-buried in the slope soil, and the drainage outlet is opened in the upper half of the bottom beam.

[0008] The above technical scheme is adopted, and the beneficial effects of the utility model are as follows: the anti-skid device for the roadbed slope, the top beam and the bottom beam are respectively pre-buried at the top and the root of the slope, and a plurality of drainage grooves are also laid on the slope surface. The top beam is provided with a plurality of water outlets along the side, and the bottom beam is provided with a plurality of drainage outlets along the side, and the two ends of the drainage groove are respectively connected to the water outlet and the drainage outlet.
