[0028] The following is a further detailed description of the specific implementation of the present utility model in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] In the related art, the cross-section of the concrete anti-slide pile is rectangular, which is not easy to produce soil arch, and the soil arch effect cannot be well utilized to fix the landslide body. Therefore, the existing concrete anti-slide piles have a poor fixing effect on the landslide body. At the same time, due to the large width of the landslide body, the force differences of the concrete anti-slide piles at different positions are large, resulting in local concrete anti-slide piles being damaged under the influence of different factors such as rainfall and the movement distance of the landslide body, thereby causing the landslide body to become unstable.
[0031] In view of this, if Figure 1-Figure 3 As shown, some embodiments of the utility model provide a landslide body 2 support device, including: a concrete pile 1, a flexible blocking mechanism and a steel bar assembly; a plurality of concrete piles 1 are provided, and the plurality of concrete piles 1 are arranged at intervals along the surface of the landslide body 2, and the width of each concrete pile 1 is arranged incrementally along the flow direction of the landslide body 2; the flexible blocking mechanism is arranged between the plurality of concrete piles 1, and the flexible blocking mechanism is extended and arranged along the width direction of the landslide body 2; the steel bar assembly is arranged inside the concrete pile 1.
[0032] In the above embodiments, the structure and shape of each concrete pile 1 are consistent. Taking a concrete pile 1 as an example, the concrete pile 1 can be cast by concrete. The side of the concrete pile 1 close to the rear edge of the landslide body 2 can be set as a plane to facilitate better blocking of the landslide body 2, and the side of the concrete pile 1 close to the front edge of the landslide body 2 is set as a plane, and the width of the concrete pile 1 is arranged in increasing order along the flow direction of the landslide body 2, so that when the landslide body 2 contacts the concrete pile 1, the contact area gradually increases, and a platform is provided at the first contact position, which can more easily form a soil arch, thereby better fixing the landslide body 2, and the concrete pile 1 is provided with a platform. The lower ends of the piles 1 pass through the landslide body 2 and extend into the sliding surface 3 below for better fixation. The upper ends of the concrete piles 1 are not lower than the height of the landslide body 2. That is, at the installation position of the concrete piles 1, the height of the concrete piles 1 is flush with the surface of the landslide body 2, or higher than the surface of the landslide body 2. Furthermore, the steel bar assembly is buried in the concrete piles 1. At least one steel bar assembly is buried in each concrete pile 1, and the length direction of the steel bar assembly can be arranged parallel to the length direction of the concrete pile 1. The steel bar assembly can increase the strength of the concrete pile 1, thereby preventing the concrete pile 1 from breaking when the landslide body 2 moves.
[0033] There can be multiple flexible blocking mechanisms, and the multiple flexible blocking mechanisms can be arranged at intervals along the sliding direction of the landslide body 2. The flexible blocking mechanisms can be made of stretchable flexible materials. The flexible blocking mechanisms are relatively long and extend along the width direction of the landslide body 2. The flexible blocking mechanisms are arranged corresponding to the multiple concrete piles 1, so that along the flow direction of the landslide body 2, the flexible blocking mechanisms can cover the multiple concrete piles 1, so that the landslide body 2, which previously had inconsistent moving speeds and inconsistent weights at various positions, can be blocked by the flexible blocking mechanisms. The moving speeds of various parts of the landslide body 2 are more consistent, and the thrust of the landslide body 2 can also be effectively diffused, reducing the thrust of the landslide body 2 transmitted to the concrete piles 1, thereby improving the overall stability of the landslide body 2.
[0034] Some embodiments of the utility model provide a landslide body 2 support device, comprising: a concrete pile 1, a flexible blocking mechanism and a steel bar assembly; a plurality of concrete piles 1 are arranged at intervals along the surface of the landslide body 2, and the width of each concrete pile 1 is arranged in increasing order along the flow direction of the landslide body 2, so that when the landslide body 2 moves, the landslide body 2 contacting the concrete pile 1 can be piled up, and the two sides of the concrete pile 1 are used as the arch feet of the soil arch, so that the soil arch is more easily formed, thereby improving the fixing ability of the landslide body 2, and the flexible blocking mechanism can disperse the thrust of the landslide body 2 to avoid excessive pressure on a single concrete pile 1, and the steel bar assembly is arranged in the concrete pile 1 to increase the strength of the concrete pile 1. The technical problems of the poor fixing effect of the landslide body 2 and the easy destruction of the concrete anti-slide pile leading to the instability of the landslide body 2 in the prior art are solved, and the landslide body 2 is fixed more firmly by forming a soil arch, while avoiding the destruction of the concrete pile 1 due to uneven force, and avoiding the instability of the landslide body 2.

Moreover, by providing the through hole 5, the material used for the concrete pile 1 can be reduced, thereby reducing the cost.
[0039] In some optional embodiments, the steel bar assembly includes a first steel bar 6, a second steel bar 7 and a third steel bar 8; the first steel bar 6 is arranged on one side of the concrete pile 1 close to the rear edge of the landslide body 2, and the second steel bar 7 and the third steel bar 8 are respectively arranged away from each other along the width direction of the landslide body 2.
[0040] In the above embodiment, the first steel bar 6, the second steel bar 7 and the third steel bar 8 are arranged parallel to each other and are respectively parallel to the length direction of the concrete pile 1, wherein the first steel bar 6 can be arranged below the plane of the end of the concrete pile 1 close to the rear edge of the landslide body 2 to increase the strength of the plane. When the landslide body 2 moves and scours the plane, the first steel bar 6 can reinforce the plane to prevent the plane from breaking and the concrete pile 1 from breaking. The second steel bar 7 and the third steel bar 8 are arranged on two bosses at intervals along the width direction of the landslide body 2. The second steel bar 7 and the third steel bar 8 can reinforce the two bosses respectively, so that when the landslide body 2 moves and forms arch feet at the two bosses, the two bosses are strong enough.

The larger the width of the landslide body 2, the greater the number of concrete piles 1 arranged in the pile body set, so that on landslide bodies 2 of different widths, multiple pile body sets are provided, and the multiple pile body sets are evenly arranged along the flow direction of the landslide body 2, and the concrete piles 1 in each pile body set pass through the landslide body 2 and are inserted into the sliding surface 3 for fixed connection, so that the multiple concrete piles 1 are arranged in order, and the number of concrete piles 1 can be adaptively adjusted in the face of landslide bodies 2 of different widths, so that the landslide body 2 can be better fixed.
