Abstract

The invention discloses a method for rapidly coagulating and curing a soft foundation of dredger fill. The method comprises the following steps: step 1, analyzing basic properties of the dredger fill;step 2, carrying out a dredger fill unit body test according to a result of the step 1, and determining an optimal ratio of components including a flocculating agent, gypsum, quicklime, sodium carbonate, an FDN water reducing agent, water glass, triethanolamine and the like in a curing agent formula, so as to rapidly flocculate and effectively cure the dredger fill; step 3, determining the optimal ratio according to an experiment result of the step 2, and mixing the dredger fill and a curing agent by utilizing an accurate material mixing system; step 4, carrying out foundation reinforcement on the dredger fill by utilizing a mixture in the step 3; and step 5, detecting and checking the soft foundation of the dredger fill. The invention provides the method for rapidly coagulating and curing the soft foundation of the dredger fill; and aiming at current situations and disadvantages of foundation treatment, rapid coagulation and curing of suspended particles are realized.

Description

technical field [0001] The invention relates to a method for rapid coagulation and solidification of dredging fill soil soft foundation. Background technique [0002] Dredging fill, also known as flush fill, is a fill formed by hydraulic flushing of mud and sand. It is one of the common artificial fills along the coast of my country. It is mainly due to the improvement or dredging of river channels, or due to the need for industrial and agricultural production. Or when filling some areas near rivers and rivers, high-pressure mud pumps are used to discharge the mud and sand dug out by dredgers through mud pipes to the areas that need to be filled and the accumulation of mud and sand. The former is planned and purposeful filling. , while the latter is accumulated without purpose, and after sedimentation and drainage, a large area of ​​flushing and filling soil is formed. [0003] Due to the shortage of land resources and the need for port dredging, land reclamation has become t...
