AI Technical Summary

Technical Problem

Existing reinforced embankment filling methods are costly, make it difficult to effectively utilize waste sludge resources, and the sludge soil has low strength and poor stability, affecting project quality and sustainable development.

Method used

The method combines crushed, reshaped, and solidified sludge soil with reinforcement technology. Solidified soil is formed by adding a solidifying agent to the sludge, which is then crushed into reshaped soil and alternately laid with reinforcement materials to form a composite structure. The friction and interlocking between the reinforcement materials and the soil improve the bearing capacity and stability of the soil.

Benefits of technology

It reduced project costs, enabled the resource utilization of waste sludge, improved the overall stability and long-term service performance of the embankment, conformed to the concept of sustainable development, and reduced the dependence on traditional sand and gravel materials.

Abstract

The application discloses a method and structure for filling embankment by using broken and remolded solidified sludge soil mixed with reinforcement technology. The method is characterized in that: a solidifying agent is mixed into the waste sludge, and the waste sludge is stirred, maintained and broken to form the remolded solidified soil with reasonable gradation, the remolded solidified soil is sequentially layered and paved, and the reinforcement material is alternately laid to form the staggered reinforced composite embankment body. The reinforcement material is arranged along the full width of the cross section of the embankment, the laying direction is perpendicular to the center line of the embankment, and the reinforcement material is folded and wrapped or anchored at the slope to realize the collaborative stress of the reinforcement material and the solidified soil. The remolded soil layer after solidification provides the bearing and compression resistance, the reinforcement layer disperses the stress through the tensioning effect, and the lateral displacement and sliding damage are inhibited, so that the overall stability and deformation control ability of the embankment are significantly improved. The method is simple in construction, can realize the resource utilization of the waste sludge, has high bearing capacity and excellent shearing resistance, and is suitable for the fields of soft soil foundation and renewable filling engineering.
