As for the soil cement-mixing wall, it is possible to utilize wide-ranging in the waterproof earth retaining wall, in the resistance earth retaining structure and the dead water wall. Standard wall thickness of Soil cement-mixing wall method is Ø650mm and Ø850mm. In case of Ø850mm walls, it is superior in yield waterproof characteristic and high reliability at deep retaining structure.
SMW method operates the based machine, the earth auger, the screw and the plant which responds to purpose combining with the optimum. For example, when it is the hard ground where the preceding pre-boring is necessary, changing to the single auger screw for pre-boring. SEMW provides different Drilling Tools, the combination of Cutter Head and Shaft form, as per specified soil condition for rapid drilling speed and keep long service life for Drilling Tools.
Features of SMW Method High Waterproof Effect
Soil cement-mixing wall is uniform with the unique mixing mechanism which provides the mixing wing and the traveling wing alternately. Furthermore, the elements are jointed with each other through lap system, it is superior in waterproof charac- teristic in comparison to conventional method.
Little Influence on Circumferential Area of Foundation, no Ground Subsidence
Shortening in terms of works
Because in site earth mixing system with one process, period of works is shorten in comparison with conventional method, and superior in economical efficiency.
Standard mixing column diameter is Ø550 - 650 mm, but to correspond to the much deeper requirement recently, mixing column diameter Ø850 - 900 mm has become possible due to the reinforcing material having big section modulus be able to insert.
As for depth of wall longest for SEMW Super Auger is 55 m.
