Anti-slide pile of jointed arch structure

Abstract

The invention relates to an anti-slide pile of a jointed arch structure. The anti-slide pile of the jointed arch structure is formed by jointing a plurality of reinforced concrete single pile bodies and arch structures. The cross sections of the reinforced concrete single pile bodies are all isosceles trapezoids, and anti-slide teeth are arranged on the two side faces of each single pile body to form friction sections; one side of the longitudinal section of the short bottom side of the isosceles trapezoid serves as a pile rear end of the corresponding single pile body for bearing landslide thrust, one side of each pile rear end is a pressure bearing region, the longitudinal section of the long bottom side of each isosceles trapezoid serves as a pile front end, and one side of each pile front end is a tensile region; the arch structures are also reinforced concrete structures and are connected between every two single pile bodies, and the arch structures evenly transmit the landslide thrust among the single pile bodies to the two sides of the corresponding isosceles trapezoids. The friction sections of the anti-slide pile enhance the anti-slide effects of the side of the pile, and the anti-slide capacity of the anti-slide pile is improved. When the anti-slide pile of the jointed arch structure is used, an unequal distance distributing method is adopted, and jointed arch pile distance layout dense in the middle and thin on the two sides is formed. The anti-slide pile is large in overall rigidity, pile tip displacement is small, and pile distances can be enlarged properly to reduce the number of anti-slide piles and lower project construction cost.

AI Technical Summary

Benefits of technology

The present invention describes a composite arch structure anti-slide pile that combines reinforced concrete single piles with an arch structure. The advantages of this design are as follows: 1. The combination of the reinforced concrete arch structure and the single anti-slide piles enhances the overall rigidity of the pile row, improving the anti-slide effect. 2. The cross section of the anti-slide pile is designed as an isosceles trapezoid with a wide front and a narrow back, and the reinforced concrete arch structure faces the inside of the landslide. This design helps evenly distribute the landslide thrust load to the anti-slide pile. 3. Both the pile and arch structure are made of reinforced concrete and are connected by reinforcing steel bars, making construction and maintenance easier. 4. The cantilever pile design of the invention reduces pile top displacement and improves the overall force status of the pile body by combining it with the reinforced concrete arch structure. 5. The addition of anti-slip teeth on the side of the anti-slide pile creates a friction section, which enhances the anti-sliding effect by promoting soil arching between the piles. The high overall rigidity of the combined arch structure allows for increased spacing and reduced number of anti-slide piles, resulting in reduced steel and concrete consumption and project investment.

Problems solved by technology

This patented technical solution described in this patents relates to improving the performance of roads or tunnels during heavy rain events caused by slippage between rocks and ground surfaces. While traditional methods like preventing slide failures with fixed posts can be effective at reducing impact from slidges, they also increase costs associated with them. To address this issue, researchers developed an improved version called Anti-Slip Piled (ASP) that uses multiple rows of anti -pilts instead of one row per pillar. These techniques aimed towards achieving greater strength without adding extra weight compared to existing solutions while still maintaining their efficiency.
