Embodiment 1
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0039] refer to figure 1 , is the overall green protective structure of the roadbed slope disclosed by the present invention, comprising a slope body 1, the surface of the slope body 1 is embedded with a main solid frame 2, the main solid frame 2 is grid-shaped, and the main solid frame 2 is fixedly connected with an anchor 3. The bottom of the anchor 3 extends toward the interior of the slope 1 until it penetrates below the surface of the slope 1, so that the anchor 3 anchors the main solid frame 2 and the deeper structure of the slope 1 together, and the main solid frame 2 It is not easy to move, and it plays a role in fixing the surface of the slope body 1, so that the surface layer of the slope body 1 is not easy to move, and the stability of the slope is improved.
[0040] refer to figure 1 and figure 2 , the main solid frame 2 is a reinforced concre...
Embodiment 2
[0045] The construction method of the integral green protective structure of the roadbed slope includes the following steps:
[0046] S1: Dig out a grid-shaped groove on the surface of the slope body 1, bind the steel cage in the groove, insert the bottom of the anchor tube 21 into the slope body 1, make the axis of the anchor tube 21 perpendicular to the surface of the slope body 1, and Weld the anchor tube 21 on the reinforcement cage;
[0047] S2: Support the formwork outside the reinforcement cage, then pour concrete, after the concrete hardens, form the main solid frame 2, and remove the formwork;
[0048] S3: Insert the anchor rod 311 into the limit groove 322, insert the anchor piece 3 into the anchor cylinder 21, and after inserting to a certain depth, pull out the outer cylinder for a section, then continue to insert the outer cylinder downward, and rotate the inner rod 32, until the fixing hole 4 of the inner rod 32 is aligned with the fixing cylinder 22, insert the...

Abstract
The invention relates to a roadbed slope overall environment-friendly protection structure and a construction method thereof, and belongs to the technical field of slope protection structures. The roadbed slope overall environment-friendly protection structure comprises a slope body, a main fixing frame is arranged on the surface of the slope body in an embedded mode, is in a grid shape and is fixedly connected with anchoring parts, the anchoring parts comprise outer rods and inner rods, the inner rods are inserted into the outer rods, the inner rods are slidably connected with the outer rods,a plurality of anchoring rods are hinged to the bottom end of each outer rod, the hinging axes of the anchoring rods are perpendicular to the axes of the outer rods, the bottom ends of the inner rodsare fixedly connected with inserting ends, limiting grooves are formed in the end faces, facing the inner rods, of the inserting ends, the ends of the anchoring rods can be inserted into the limitinggrooves, and the positions, close to the inserting ends, of the circumferential faces of the inner rods are fixedly connected with elastic parts capable of enabling the anchoring rods to serve as hinging ends to get away from the inner rods. The roadbed slope overall environment-friendly protection structure and the construction method thereof have the effect of improving slope stability.
Description
technical field [0001] The invention relates to the technical field of slope protection structures, in particular to an integral green protection structure for roadbed slopes and a construction method thereof. Background technique [0002] At present, the main forms of slope protection are traditional masonry protection and ecological protection. Traditional masonry protection includes masonry rubble and concrete hollow hexagonal blocks, etc. Ecological protection includes direct seeding of plants, guest soil spraying, plant ecological bags and Ecological grass blanket, etc. [0003] The existing Chinese patent whose notification number can be referred to is CN108442392A discloses a kind of roadbed slope integral green protection structure and its construction method. The protective structure includes: concrete cast-in-place drainage grooves arranged at intervals along the slope of the subgrade; concrete cast-in-place water cut-off shoulders arranged at the top of the slope...
