Embodiment 1

[0071] Such as figure 2 As shown, a green protective structure for deep cuttings according to the present invention includes a side ditch platform 3, a first side slope 51 is arranged on the outside of the side ditch platform 3, and a plurality of anchor rods are arranged on the first side slope 51 In the component 4, a side slope platform 52 is arranged on the top of the first side slope 51, a first anchor pile 53 is arranged in the substrate 6 below the side slope platform 52, and a first anchor pile 53 is arranged on the first side slope 51. Some of the first ornamental vegetation1.

[0072] Preferably, there are several first anchor piles 53 , and all the first anchor piles 53 are arranged at intervals along the length direction of the slope platform 52 .

[0073] Preferably, the top of the first anchor pile 53 is flush with the slope platform 52 .

[0074] Preferably, the anchor rod assembly 4 includes an anchor rod skeleton 41 located on the first side slope 51 and se...

Embodiment 2

[0085] Such as figure 2 As shown, a cutting protection system described in this embodiment includes a roadbed 7, and at least one side of the roadbed 7 is provided with the green protection structure for deep cuttings as described in Embodiment 1.

[0086]Preferably, a side ditch 71 is provided between the roadbed 7 and the side ditch platform 3 , and the side ditch 71 is arranged along the length direction of the roadbed 7 for draining surface water.

[0087] Preferably, a blind ditch 72 is arranged below the side ditch 71, and the blind ditch 72 is arranged along the length direction of the subgrade 7 for guiding and draining groundwater.

[0088] Preferably, micro piles 31 are arranged in the base 6 below the side ditch platform 3 .

[0089] Before carrying out the construction of side ditch and blind ditch, in order to prevent the side ditch platform 3 from being unstable due to the construction of side ditch and blind ditch, the earthwork on the side of side ditch platf...

Embodiment 3

[0095] Such as figure 2 As shown, the present embodiment discloses a construction method for forming a green protection structure for a deep road cutting as described in Embodiment 1, comprising the following steps:

[0096] Excavating the earthwork to form the slope platform 52;

Abstract

The invention relates to the field of side slope protection, in particular to a deep roadcut green protective structure, a roadcut protective system and construction methods of the deep roadcut greenprotective structure and the roadcut protective system. The deep roadcut green protective structure comprises a lateral ditch platform; a first side slope is disposed on the outer side of the lateralditch platform; an anchor rod assembly is disposed on the first side slope; a side slope platform is disposed at the top of the first side slope; first anchored piles are disposed in a base body belowthe side slope platform; and a plurality of ornamental plants are disposed on the first side slope. By means of the deep roadcut green protective structure, the first side slope is disposed on the outer side of the lateral ditch platform, the stability of a roadcut side slope is guaranteed through the first anchored piles and the anchor rod assembly, the visual field of a driver and a passenger is widened, the green landscape effect is good, the demand of environmental protection is better met, and the protection cost is lower.

Description

technical field [0001] The invention relates to the field of slope protection, in particular to a deep road cutting green protection structure, a road cutting protection system and a construction method thereof. Background technique [0002] In the construction of railways or roads in mountainous areas and other locations, a large number of cutting slopes usually appear. Such as figure 1 As shown, during construction, the base body 6 at the target position is generally excavated first, and the cutting slope 5 is formed, and then the cutting slope 5 is protected. The traditional reinforcement and protection measures for the cutting slope 5 are: at the foot of the cutting slope The side ditch platform 3 is provided with retaining structures 2 (between piles) retaining walls, pile-slab walls, and soil nail walls between piles, and the cutting slope 5 above the top of the retaining structure 2 adopts anchor rod (cable) frame beams, Water-cutting skeleton etc. are carried out s...
