Abstract

The invention discloses a rapid reinforcement method of dredging fill foundation by mixing curing agent and dredging fill pipeline, which comprises: step 1, determining the mixing ratio of curing agent and dredging fill soil, mixing and filling on site; step 2, strengthening the foundation ; Step 3, inspection of solidified dredger fill foundation; wherein, step 1 includes: carry out soil quality analysis to dredger fill; select curing agent type; determine the mixing ratio of curing agent and dredger fill; : Determine the shear strength index, compressive modulus and thickness of the reinforced soil layer of the solidified dredger fill to meet the requirements of the characteristic value of the foundation bearing capacity and the allowable deformation value of the foundation treatment design; Reinforcement; determine curing conditions and curing time. The on-site mixed dredging method for solidified dredged fill provided by the present invention can greatly reduce the construction period, reduce the process of silt consolidation and foundation reinforcement in conventional dredged fill foundation treatment, save engineering cost, rationally utilize resources and protect the environment .

Description

technical field [0001] The invention relates to a technical method for on-site mixing and strengthening of dredging fill soil, in particular to a rapid reinforcement method for dredging fill foundations in which a curing agent is mixed with a dredging fill soil pipeline. Background technique [0002] During the dredging process of ports and waterways, a large amount of dredging mud is usually produced. The dredged mud produced in the dredging project is usually stacked or discarded, and it takes up a lot of land to stack it. However, the dumping of mud in the ocean has seriously affected the effective use of marine resources, and has caused damage to the water environment, geological environment, and ecological environment of the ocean. Larger damage, the contradiction between dredging mud dumping and marine environmental protection has become increasingly prominent, and it is increasingly restricted by various aspects. [0003] In the construction process of coastal projec...
