AI Technical Summary

Technical Problem

Existing technologies make it difficult to apply loads to the surface of sludge in stockpiles, resulting in poor negative pressure consolidation treatment. At the same time, the resource utilization of crop straw is difficult, leading to serious environmental pollution.

Method used

A pneumatic loading device for filling silt with straw is used. By filling the straw rope with compressed air, the straw rope expands and drives the permeable plate to move relative to the silt, applying vertical and horizontal positive pressure to the silt to achieve rapid consolidation.

Benefits of technology

It enables rapid consolidation of silt and effective drainage of water, provides a temporary hard shell layer to support construction, solves the problem of low silt strength, and promotes the resource utilization of straw.

Abstract

The application discloses a kind of straw-containing yard hydraulic fill sludge air pressure loading device and rapid consolidation method, belong to the field of foundation treatment, a kind of straw-containing yard hydraulic fill sludge air pressure loading device and rapid consolidation method, including upper hard water-permeable plate and lower hard water-permeable plate, the upper hard water-permeable plate and lower hard water-permeable plate are symmetrically arranged, the upper hard water-permeable plate and lower hard water-permeable plate side wall are all provided with a plurality of through holes, the upper hard water-permeable plate and lower hard water-permeable plate are provided with straw rope inflation body between center, it can be realized, into certain air pressure air in straw rope inflation body, make inflation body expand, cause the straw rope around inflation body to bend and two ends shrink, to make the upper and lower hard water-permeable plate connected with two ends of inflation body have relative movement tendency, since two plates are filled with sludge, so two plates exert certain vertical positive pressure to sludge, to achieve the purpose of loading on yard sludge surface.
