Landslide and slope governing non-vertical type antiskid pile structure and installation method

Abstract

The invention discloses a landslide and slope governing non-vertical type antiskid pile structure and an installation method. The method includes the steps that collecting and investigating are conducted on the physical mechanical parameters of the landslide type, the scale, the landslide mass thickness, the landslide perimeter, the sliding face type, the sliding face space position, a sliding main shaft and a rock-soil body in the landslide affection range according to reconnaissance data; landslide thrust calculation is conducted according to a mechanical model recommended by current specifications based on the data obtained through collecting and investigating; and design of geometrical parameters such as the pile length, the pile body anchorage section length, the pile interval and thepile body section size is conducted according to the landslide thrust obtained through calculation; non-vertical type antiskid piles and the rock body in the landslide affection range are rotated into vertical type antiskid piles according to the preset angle, then pile body internal force calculation is conducted, and reinforcement is conducted on the non-vertical type cast-in-place concrete antiskid piles; and construction is conducted according to the designed geometrical parameters and reinforcement. By means of the landslide and slope governing non-vertical type antiskid pile structure and the installation method, a lot of money can be saved in the landslide and slope governing process, the construction period is shortened, and meanwhile environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a non-vertical anti-slide pile structure and installation method for landslide and side slope treatment. Background technique [0002] The construction of road traffic, the development of hydraulic and hydropower projects, the mining of open-pit mines, and the large-scale expansion and reconstruction of cities all involve slope engineering. my country has a vast territory and complex natural conditions. Due to environmental changes, climate changes, and unreasonable excavation and filling of rock and soil by humans, natural or artificial slope. [0003] Under certain topographic and geological conditions, due to changes in external conditions, various natural or man-made factors (such as long-term water infiltration, weakening the supporting force of the lower part of the slope, etc.), destroy the mechanical balance of the rock and soil, making the hillside unsustainabl...

Problems solved by technology

[0021] In addition to setting the crown beam on the top of the pile, it is difficult to set up a firm connection for the anti-slide pile at other parts of the non-anchor section of the pile body, which is not conducive to the coordinated work of the entire anti-slide pile support system;

[0022] After completion, the anti-slide pile support structures are all reinforced concrete structures, which are difficult to coordinate with the surrounding environment
