Description

Technical Field

[0001] The utility model relates to the technical field of foundation reinforcement, in particular to a high-salt sludge foundation reinforcement device. Background Art

[0002] When encountering a foundation with high-salt silt, the high-salt silt is a soft soil layer with high water content, high compressibility, high sensitivity, low strength, low density, low permeability, low bearing capacity, easy to frost heave, etc. It has poor engineering performance and is easy to deform under pressure. Under vibration or loading conditions, rheology, thixotropy or consolidation of the soft soil itself may occur, causing the ground of the site to settle and deform, resulting in uneven settlement of the building and even structural damage. At the same time, salt corrodes the foundation of the building and underground facilities, affecting their service life, and requires human reinforcement treatment. Common methods include stone chip cushion layer, sand cushion layer, mixed ash soil backfill and compaction, etc.

[0003] At present, it is common to modify the soil by adding curing agent and anti-salinity composite admixture to make the soil composite foundation soil standard. By reducing the tamping energy and increasing the number of tamping times, the consolidation of silt soft foundation is accelerated, and the soft foundation consolidation settlement and secondary consolidation settlement occur in advance, thereby improving the bearing capacity and consolidation degree of the foundation, and reducing the post-construction settlement and uneven settlement of the foundation.

[0004] Curing agent and anti-salinity composite admixture are put into the high-salt silt foundation, and the foundation soil is directly turned over for stirring and curing. The ratio of the agent to the foundation soil is difficult to control, which easily leads to waste of the agent. Utility Model Content
