A mixing pile ship for underwater soft foundation construction

Abstract

The invention discloses a stirring pile ship used for underwater soft foundation construction. The stirring pile ship comprises a double-body ship, a hollow construction work area is arranged between the front end and the tail end of the double-body ship, a longitudinal movement trolley capable of moving in the longitudinal direction of the construction work area is arranged on two ship bodies of the double-body ship, and a transverse movement trolley capable of moving in the transverse direction of the construction work area is arranged on the longitudinal movement trolley. The transverse movement trolley is provided with a stirring device used for working on an underwater soft foundation located below the construction work area. The stirring pile ship has the advantages that the draft and stranding work construction can be conducted in the various conditions with soil, with ebb water flow and without ebb water flow by means of the double-body ship, high bearing and storing buoyancy is achieved, and reliable work stability and adaptability are achieved; a construction device can be used for conducting construction work on the underwater soft foundation needing to be constructed at any time by moving the longitudinal movement trolley and the transverse movement trolley, the work area is large, and therefore the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to a soft foundation treatment and construction machine, in particular to a stirring pile ship used for underwater soft foundation construction, which can meet the actual construction operation requirements in different soils and with or without ebb water flow conditions. Stirring can make the underwater soft foundation soil form a cement-soil consolidation body with a certain strength, which improves the bearing capacity of the underwater soft foundation and improves the compression, shearing and water permeability characteristics of the underwater soft foundation soil. Background technique [0002] With the rapid development of the marine economy, emerging industries and population will continue to concentrate in coastal areas, which will accelerate the development of ecological reclamation construction. The backfilling of the enclosed area mainly adopts dredging silt. Due to the high water content of dredged silt, fine soil part...

AI Technical Summary

Problems solved by technology

[0002] With the rapid development of the marine economy, emerging industries and population will continue to concentrate in coastal areas, which will accelerate the development of ecological reclamation construction. The backfilling of the enclosed area mainly uses silt dredging. Due to the high water content of the dredged silt, fine soil particles, It has strong fluidity, so it is difficult to consolidate under natural conditions for three to five years, which seriously affects the construction process of the reclamation area in the later stage

On the other hand, due to the large cohesion and low bearing capacity of mud flats and underwater soft foundations, it is impossible to carry out engineering construction

However, general-purpose construction machinery and equipment cannot be used for construction on silt, and the existing silt solidification machine can no longer meet the needs of engineering construction.
