Description
Technical Field
The invention relates to the technical field of civil engineering supports, in particular to a cutting slope anti-slip structure and a construction method thereof.
Background
China is a world mountain land and a large country, the area of the mountain land occupies about 2/3 of the total land and soil area, the terrain and geology of most mountain areas are complex, the natural environment conditions are fragile, high-grade roads are built in the mountain areas and are comprehensively influenced by climate, geology and construction activities, and the phenomenon that cutting slopes collapse frequently occurs in the road construction and operation processes. At present, a method and a structure for rapidly treating side slope landslide are urgently needed to prevent secondary damage of the side slope so as to ensure the safety and stability of the landslide side slope.
At present, the slope stability problem solved by the engineering world mainly has the following two aspects.
Firstly, unloading and clearing: adopt in the design and slow down the side slope, increase big platform, reduce the load of slope top, reduce gliding force. The method has simple construction process, but has the following problems: the newly increased land occupation is needed for relieving the side slope, and the method is not suitable for being adopted particularly when a structure is arranged on the top of the slope; a large amount of waste is added in the process of relieving the side slope, and outward transportation and stacking need to be considered; when the side slope is relieved, the rain season is avoided, and new landslide is probably caused by unreasonable slope cutting.
Secondly, supporting and blocking protection: in the design, the existing side slope is reinforced by adopting modes such as anti-slide piles, pile foundation joist retaining walls, anchor cables (rods) and the like, and the anti-slide force of a slope body or slope toe is increased. The method has wide application range, but has the following problems: the construction period of the anti-slide pile is long, and the square pile with better anti-slide capability cannot be constructed mechanically; the pile foundation joist retaining wall masonry amount is large, and the construction is complicated due to the fact that the pile foundation joist retaining wall relates to a plurality of structures such as a retaining wall, a joist and a pile foundation; the anchor cable (rod) has a service life as a steel member, and can be loosened with time, so that the anchoring force is reduced and even the anchor cable (rod) fails.
Therefore, in order to solve the above problems, a cutting slope collapse prevention structure is needed, and the cutting slope collapse prevention structure has a structure for treating slope collapse, which has the advantages of small influence on the surrounding environment in the construction process, high construction speed and good supporting effect.

The pile body comprises a reinforcing rib of a plate-fin structure and a pile body pouring material, the reinforcing rib is vertically arranged in the pile hole and is coaxial with the axis of the pile hole, and the space between the pile hole and the reinforced rib is filled with the pile body pouring material; the reinforcing rib can be hoisted mechanically, the efficiency is high, and the bearing capacity can be exerted quickly. The end face of the wing plate in the plate-fin structure faces to the predicted slumping direction of the soil foundation slumping layer, and bending moment caused by the soil foundation slumping layer is resisted through the web plate. And because the reinforcing rib adopts a plate-fin structure, the pile body casting material is not easy to separate from the pile body casting material under the action of torque after being filled with the pile body casting material, and the pile body casting material is preferably concrete in the embodiment. In the plate-fin structure, the wing plates can be provided with a plurality of wing plates, and the included angle between the wing plates and the web plate is not limited to a right angle, namely, the included angle between the wing plates and the web plate can also be an acute angle or an obtuse angle.
Furthermore, a connecting beam for fixing the pile bodies is arranged between every two adjacent pile bodies.

The connecting beam comprises a cross beam and a longitudinal beam, and the cross beam can be welded with two adjacent reinforcing ribs in the same row by adopting shorter I-shaped steel; the cross beam can also adopt longer I-shaped steel, and the same row of reinforcing ribs are welded on the same cross beam. The longitudinal beams are positioned between two rows of adjacent reinforcing ribs.
The beam wing plates face the predicted slumping direction of the soil foundation slumping layer and are positioned on the same plane with the reinforcing rib wing plates and are welded and fixed, and the beam web plates are perpendicular to the reinforcing rib web plates. The longitudinal direction of the longitudinal beam is substantially the same as the expected slumping direction of the soil foundation slumping layer. The longitudinal beams can be welded with the reinforcing ribs and also can be welded with the cross beams. The distance between the pile bodies is not less than 3 times of the diameter of the pile hole, preferably 1m to 1.2m, and is 1m in the embodiment.
Furthermore, the connecting beam is coated with a protective layer. Each connecting beam can be independently coated with a protective layer to form a grid structure, and the protective layer can also coat all the connecting beams to form a plate-shaped structure.
