Method for constructing cement soil underground continuous wall under complex geological condition

The invention relates to the technical field of building engineering, in particular to a method for constructing a cement soil underground continuous wall under a complex geological condition. The method aims to solve the problems of difficult cutting, slow construction progress, large equipment wear and the like of an existing TRD working method in a high-strength dense gravel land layer. The method comprises the specific steps that the geological condition is explored, the characteristics of the soil within the depth range are surveyed, and corresponding test wall forming work is carried out; double-wheel milling deep stirring cutting construction is carried out; gravel soil cleaning construction is carried out by an underground continuous wall grooving machine grab bucket; plain fill backfill construction is carried out; and TRD cement soil continuous wall construction is carried out. The method for constructing the cement soil underground continuous wall under the complex geological condition has the bene
