Spiral Drum Mixing Pile Machine

Abstract

The invention discloses a spiral roller type mixing pile machine. The spiral roller type mixing pile machine comprises a working platform, a spiral roller type running device and a mixing working device. The working platform is composed of a main platform, an amplitude variation platform, a rotary platform and a moving platform. The amplitude variation platform comprises two side platforms which are symmetrically arranged on the two sides of the main platform and can slide towards the inner sides and the outer sides of the sides of the main platform. The spiral roller type running device is mounted at the bottoms of the two side platforms. The rotary platform is mounted on the main platform. The tail of the rotary platform is arranged in the moving platform, and the moving platform can slide on the rotary platform in the front-and-back direction. The stirring working device is mounted on the moving platform. The spiral roller type mixing pile machine has the advantages that work reliability, safety, construction efficiency and construction quality are high, environment protection is achieved, and adaptability is good; a solidification body with integrity, water stability and certain strength can be formed by sludge and mud flat soft foundation soil through mixing; the bearing capacity is improved; the characteristics of compression, shear and water permeability are improved; and the actual construction working requirements can be met under different work conditions.

Description

technical field [0001] The invention relates to a soft foundation treatment and construction machine, in particular to a spiral drum-type stirring pile machine used for the treatment and construction of soft foundations of silt and tidal flats, which can make silt and soft foundation soil of tidal flats form integral , water stability and a certain strength of the consolidated body, which improves the bearing capacity of silt and tidal flat soft foundation soil, improves the compression, shearing and water permeability characteristics of silt and tidal flat soft foundation soil, and it can meet the requirements of different working conditions. actual construction work requirements. Background technique [0002] With the rapid construction of the marine economy, emerging industries and population will continue to concentrate in coastal areas, accelerating the development of ecological reclamation construction. At present, dredging mud is mainly used for backfilling in the su...

AI Technical Summary

Problems solved by technology

At present, dredging mud is mainly used for backfilling in the surrounding area. However, on the one hand, due to the high water content, fine soil particles and strong fluidity of the dredged mud, it is difficult to consolidate under natural conditions, which seriously affects the later stage of dredging. On the other hand, due to the large plasticity index and void ratio, low gravity, poor compressibility, poor permeability, high cohesion, and low bearing capacity of the soft foundation of silt and tidal flats, general-purpose Construction machinery and equipment cannot carry out normal construction and cannot meet the needs of engineering construction
