Problems solved by technology
However, the layout of the micro-pile group is generally designed as a straight line perpendicular to the sliding direction, relying only on the shear or bending resistance of the micro-pile group to resist the thrust of the landslide, without exerting the anti-sliding force of the side wall of the landslide.
In addition, in the treatment of convective landslides, supporting structures such as anti-slide piles or micro pile groups need to be combined with special underground drainage measures, and the overall cost is high.

Embodiment Construction
[0026] Such as figure 1 As shown, an intelligent drainage and anti-sliding arch ring reinforcement method for fluid landslides involves driving multiple rows of micro piles 3 and drainage hollow piles 4 into the landslide 1, and connecting them with connecting beams 5 at the top of the piles. Arranged in a radian, the arch ring 2 is formed together with the stratum of the side wall, relying on the anti-slip force of the arch ring 2 and the anti-slip force of the side wall to jointly resist the thrust of the landslide. The micro-pile 3 is constructed by drilling, strong reinforcement, and grouting; the drainage hollow pile 4 is a prefabricated pile, and the pile body reserves a drainage hole 6 so that the water in the landslide can penetrate into the hollow part of the drainage hollow pile 4. The filter geotextile 9 is arranged on the outside of the hollow pile 4 to prevent the drainage hole 6 from being blocked. A pumping pipe 10 is arranged in the hollow part of the drainage...

The invention discloses an arch ring reinforcing method for intelligent drainage and slipping resistance of a flow-type landslip. A plurality of rows of miniature piles are struck into appropriate positions of the landslip, and the miniature piles are arranged on a plane according to a certain radian, so that the miniature piles and the a stratum of the side wall jointly form a miniature combined pile group arch ring; thrust of the landslip is jointly resisted by slipping resistance of the arch ring and slipping resistance of the side wall; and additionally, drainage hollow piles of a certain proportion are arranged, and water in the slipping body is discharged in the mode that the water is pumped on the ground surface. A certain number of underground water level indicators are installed in the drainage hollow piles, and the water pumping time and quantity are determined in real time according to the actual measured underground water levels to achieve intelligent drainage of the landslip.
Description
technical field [0001] The invention relates to an intelligent drainage anti-sliding arch ring reinforcement method for a fluid landslide. Background technique [0002] Fluid landslides generally refer to landslides that slide in a fluid shape after the soil is soaked and saturated under the influence of heavy rainfall or groundwater. For the treatment and reinforcement of this type of landslide, in addition to adopting commonly used support measures for reinforcement, it is very important to discharge the water in the slide body in time. The current design of landslide control generally adopts the method of retaining structures combined with drainage measures, which is expensive; and the retaining structures are mostly arranged in a straight line perpendicular to the sliding direction, which does not give full play to the anti-sliding ability of the side walls. Therefore, it is necessary to explore a more suitable control technology for flow-like landslides. [0003] At p...
