Shallow landslide control method combined with high pressure rotary jet piles and clustered miniature steel pipe piles

Abstract

The invention relates to a method for treating shallow landslide. According to the method, steel pipe piles, pile top beams, crossbeams and high-pressure rotary jet grouting piles are used. The high-pressure rotary jet grouting piles which are reinforced fully are arranged on the periphery of each micro-steel pipe pile, each two lines of the steel pipe piles or more than two lines of the steel pipe pile form a row of piles, and the steel pipe piles are arranged in a square or quincuncial manner; each pile top beam is arranged on the tops of the corresponding row of piles; tops of the steel pipes in each row of piles are embedded in the corresponding pile top beam and are connected with the corresponding pile top beam; and each two adjacent pile top beams are connected with each other through the corresponding crossbeam. The method for treating shallow landslide is flexible in space arrangement, high in adaptive capacity to environments and easy and convenient to construct, large mechanical equipment is not required to be used, disturbance to surrounding environments is small, and working hours are saved.

Description

technical field [0001] The invention relates to a method for treating shallow landslides, which is suitable for reinforcement of shallow landslides where the surrounding environment is tense and the construction site is narrow. Background technique [0002] With the increasingly tense urban land use and the increasingly complex surrounding environment, it is inevitable to encounter shallow landslide treatment problems in engineering construction. Such landslides are often small in scale, but the environmental and social impacts caused by sliding damage are relatively large. In order to avoid adverse effects, it needs to be quickly reinforced. However, traditional landslide treatment methods, such as setting anti-slide piles and anti-slide retaining walls, have poor economic efficiency, complex construction organization, long construction period, and high requirements for mechanical equipment on the construction site. , cannot be implemented in this type of landslide control ...
