Boot-type root anchor anti-sliding pile and construction method thereof

Abstract

The invention discloses a boot-type root anchor anti-sliding pile and a construction method thereof, and relates to the technical field of landslide treatment engineering. According to the technical scheme, the boot-type root anchor anti-sliding pile is characterized by comprising a pile body located in a landslide body and with the bottom end extending into the bedrock, a pile toe close to the sliding surface of the landslide body is arranged on one side wall of the bottom end of the pile body, a plurality of vertical anchor cables are arranged on the side, away from the pile toe, of the pilebody, the top end of each vertical anchor cable extends out of the top end of the pile body, and the bottom end of each vertical anchor cable penetrates through the inside of the pile body to the bottom end of a drilling hole in the bottom end of the pile body. According to the boot-type root anchor anti-sliding pile, under the condition that the anti0sliding force provided by the pile is ensured, the excavation depth of the anti-sliding pile is reduced, the construction costs are reduced, and the construction efficiency is improved; and by means of the construction method, the labor cost andthe costs of pile body concrete and steel bar can be saved, the acceleration of the project progress is facilitated, and the project cost is reduced.

Description

technical field [0001] The invention relates to the technical field of landslide control engineering, in particular to a boot-type root-anchor anti-slide pile and a construction method thereof. 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 unsustainable. The unfavorabl...

Problems solved by technology

[0005] In landslide control, anti-slide piles can provide greater anti-slide force, and they have been used since the 1960s. Later, in landslide control, they were widely used. For the excavation of anti-slide piles, most of the pile types are designed as The square shape is difficult to operate by machinery. Therefore, most of them still use manual excavation at present. For the hard rock of the sliding bed, manual excavation is very difficult. In the past few years, blasting was used, but in recent years, the control of blasting materials has been strict. Blasting is already very difficult, therefore, there is a need for a way to reduce the excavation depth of anti-sliding piles while ensuring anti-sliding force
