Soft soil foundation treated by chemical-solution-combined injection electroosmosis method and construction method of soft soil foundation

Abstract

The invention provides a soft soil foundation treated by chemical solution-combined injection electroosmosis method and a construction method of the soft soil foundation, and belongs to the technical field of processing of the soft soil foundation. A metal electrode is inserted into the soft soil foundation; different chemical solutions are injected into a positive electrode and a negative electrode respectively, and a direct current is fed; under a direct current field, water and a cation solution which have positive charges flow towards the negative electrode, and an ion solution with negative charges flows towards the positive electrode so as to form electroosmosis chemical reaction; at the same time, the water is pumped and discharged from the top of the negative electrode so as to reduce the water ratio in the soil, accelerate concretion and compaction of the soil, and enhance the strength of the soil; and precipitates produced by the chemical reaction can cement the soil particles. Compared with other soft soil foundation treatment methods, the construction method has the advantages of more environment friendliness, lower energy consumption and saved treatment cost, and large-size mechanical equipment and building materials such as cements, sand, stones and the like are not required. By the method, the construction process is simple, the operability is high, the quality is convenient to control and detect, and the intensity of the soil is enhanced obviously.

Description

technical field [0001] The invention relates to the technical field of soft soil foundation treatment, in particular to a combined chemical solution injection electroosmosis method to treat soft soil foundation and a construction method thereof. It is mainly suitable for engineering and technical fields such as soft foundation treatment of reclamation and reclamation in coastal tidal flats and depressions. Background technique [0002] With the rapid development of the national economy and infrastructure construction, reclaiming land from the sea is one of the effective ways to alleviate the shortage of land resources in coastal cities. Land reclamation is a good method for channel dredging and land formation, and it is also the main method for the formation of land reclamation in my country at present. Due to regional differences, the properties of the blown fill are different, but generally the moisture content is high, and the treatment cost required for the construction...
