Problems solved by technology

[0002] Due to the long route of the existing expressway, it has to pass through different climate zones, and there are different soil structures in the excavation section of each section of the road. Among the different soil structures, some soils are very loose. Due to the annual The role of natural factors such as soil thawing, rain impact, and groundwater level fluctuations have caused large-scale landslides on soil slopes in the excavation section, which seriously threatens road safety. Bridges and culverts are protected by engineering measures on both sides of bridges and culverts, which need to be maintained every year. When there is a flood, the protective facilities will be washed away, which directly affects the safety of the road.

Embodiment 1

[0027] A new technology for the protection of highway soil slope willow piles, including:

[0028] Slope protection:

[0029] Selection of seedlings: In order to select seedlings, three-year-old willow seedlings are used. The diameter of the seedlings reaches 3-5 cm, and the height of the seedlings is more than 2.5 meters. Choose flocculent-free varieties. After the seedlings are selected, take the trunk above the ground and cut the trunk into 1.2-meter-long willow piles or determine the length of the willow piles according to the actual situation. The diameter of the small head of the willow piles must be greater than 3 cm, but the willow piles must be Straight, the big head should be pointed, and the hole punched first does not need to be pointed;

[0030] Soil preparation: Before planting seedlings, pick up all the branches, shrubs, rattans, and gravels that germinate and affect the management of willow trees on the slope, so that the slope is clean, and then draw wires to...

Embodiment 2

[0042] Test according to the technology of the present invention:

[0043] Geographical location and topography:

[0044] The slope protection area is the side slope of the excavated section on both sides of the Hartong Highway, and the embankments on both sides of the bridge and culvert. The highway is located on the south side of the main stream of the Songhua River, the west branch of Zhangguangcai Mountain, and the low mountain and hilly area in the north of Wanda Mountain. Administratively, it belongs to counties and cities such as Acheng, Binxian, Fangzheng, Yilan, and Jiamusi in Heilongjiang Province. Rivers are densely distributed and parallel to the road, mainly including the main stream of Songhua River and its tributaries, Ash River, Ant River, Mudan River, Woken River, etc., as well as several small tributaries and streams, all of which have a certain impact on roadbed construction.

[0045] Climate Features:

[0046] The land that the highway passes through is t...
