Research on Wall Formation Technology of Cement Soil Mixing Wall with Double Wheel Milling in Lijialiang Reservoir
As a new type of equal thickness cement mixing wall construction technology,cement soil mixing wall with double wheel milling(SMC)has a broad application prospect in water conservancy engineering impermeable wall and foundation pit sealing enclosure.Based on the cutoff wall project of Lijialiang Reservoir in Yulin city,the unconfined compressive strength and permeability tests of cement mixing wall were carried out.The results show that the anti-seepage wall has a good wall formation effect and meets the engineering technical requirements.Among them,the unconfined compressive strength is greater than 3 MPa,the highest is 3.91 MPa,the permeability coefficient is less than 10-5cm/s,the lowest is 10-10order of magnitude,and the strength of the inner wall and the joint is basically the same,which can provide reference for related engineering practice.
