A method for constructing anti-slide piles using manually excavated bored piles.

By using the manual excavation method for bored pile construction, two rows of anti-slide piles were installed and connected as one unit. Anchor ropes and anchors were used to improve the stability and protection capabilities of the anti-slide piles, thus solving the problems of connection strength and stability in the construction of anti-slide piles and achieving the effect of stable slope support.

AI Technical Summary

Technical Problem

During the construction of anti-slide piles, how to ensure the connection strength and stability of the anti-slide piles and prevent slippage, toppling or breakage, while preventing soil from sliding down between the anti-slide piles.

Method used

The construction method of manually excavated bored piles is adopted. Two rows of anti-slide piles are set up and connected into one unit by connecting beams and pile slab walls. The high-level anti-slide piles are anchored in the slope by anchor ropes. The anchor ropes and anchors form a conical structure. Safety protection is provided by locking protection and pre-embedded pulley system.

Benefits of technology

It improves the connection strength and anchoring force of anti-slide piles, ensures construction safety, prevents soil slippage, and achieves the effect of stabilizing and supporting slopes.

Abstract

This invention discloses a method for constructing anti-slide piles using manually excavated bored piles, comprising: Step 1, measuring and positioning at a designated location, and constructing anti-slide piles at the corresponding location using manually excavated bored piles. Two rows of anti-slide piles are spaced apart along the slope's inclination direction, with several piles in each row located at the same height on the slope; Step 2, connecting any two adjacent anti-slide piles in the higher row using connecting beams, and simultaneously connecting any two adjacent anti-slide piles in the lower row using pile-slab walls to form a retaining structure; Step 3, connecting the anti-slide piles at both the higher and lower locations along the longitudinal direction of the slope using connecting beams; Step 4, anchoring the higher anti-slide piles within the slope using anchor ropes, which extend obliquely from the anti-slide piles towards the top of the slope and are taut. This invention ensures the connection strength, protective stability, and robust anchoring of the anti-slide piles.
