Embodiment Construction

[0020] refer to figure 2 , the obliquely arranged miniature pile structure of the present invention is used to fix the landslide body S1 on the bedrock S2. The role of the pile structure is to fix the landslide body S1 prone to landslides on the bedrock S2, and the thrust F of the landslide body is the force exerted on the micropile structure when the landslide body S1 moves.

[0021] An obliquely arranged micropile structure of the present invention is used to fix the landslide body S1 on the bedrock S2, comprising at least one set of micropile combinations passing through the landslide body S1 and fixedly connected to the bedrock S2, and each group of micropile combinations includes At least three micropiles 22, 23, 24 and the surface of the landslide body S1 are used to connect the micropiles 22, 23, 24 to the top plate 21; the micropiles 22, 23, 24 include the first micropiles 22, The second micro-piles 23 and the third micro-piles 24, the second micro-piles 23 are arran...

Abstract

The invention discloses an inclined arrangement mini pile structure. The inclined arrangement mini pile structure is used for fixing a landslide mass on a base rock. The inclined arrangement mini pile structure comprises at least one group of mini pile assembly which penetrates through the landslide mass to be fixedly connected with the base rock. Each group of mini pile assembly comprises at least three mini piles and a top plate which is arranged on the surface of the landslide mass and used for connecting the mini piles into a whole. The mini piles include the first mini piles, the second mini piles and the third mini piles. The second mini piles are perpendicular to the surface of the landslide mass. The first mini piles are arranged in an inclined mode in a direction facing the exerting direction of thrust of the landslide mass. The third mini piles are arranged in an inclined mode in the exerting direction of the thrust of the landslide mass. Lubricating interlayers are disposed between parts, located in the landslide mass, of the first mini piles and the landslide mass. By means of the inclined arrangement mini pile structure, the effect that the inclined piles towards the thrust of the landslide mass always have pre-tightening force can be ensured, and the whole mini pile structure is better in slope fixing effect.

Description

technical field [0001] The invention belongs to the technical field of landslide control and side slope reinforcement, and in particular relates to a micropile structure arranged obliquely. Background technique [0002] Micro-piles generally refer to small-diameter bored piles with a pile diameter of 70-300mm, and their slenderness is relatively large. Only light construction equipment is needed during construction, the pile position layout is flexible, the construction speed is fast, the adaptability to the construction site is strong, and the impact on the environment is small. In recent years, it has been continuously applied to landslide control, slope reinforcement and other projects. It can also be used as a support pile in basic projects such as sound insulation screens, pedestrian bridges, conveyor belts, small villas, and small shopping malls. [0003] The construction operation of micro piles is mainly divided into four stages, one is drilling according to the re...
