AI Technical Summary

Technical Problem

Existing landfill soft soil foundation reinforcement technologies suffer from problems such as pile slippage and displacement, poor positioning accuracy, high cost, low solid waste utilization rate, and poor reinforcement uniformity, making them difficult to adapt to complex and harsh geological conditions.

Method used

A multi-pile cross-connection structure is adopted, combined with a composite curing agent, and the installation blocks are connected by cross-shaped slots and reinforcing rods to form an overall linkage reinforcement system. The composite curing agent includes waste incineration secondary bottom ash powder, ordinary silicate cement and slag layer, etc., to replace part of the cement base material, thereby improving the pile positioning accuracy and soil stability.

Benefits of technology

It significantly improves the anti-settlement and anti-sliding performance of soft soil foundations in landfills, reduces construction costs, realizes the resource utilization of solid waste, and enhances the overall stability and deformation resistance of the foundation.
