Mixing blades are rotated and penetrated into ground, then powdery binders are pneumatically ejected from tip of mixing blades and mixed with in-situ soils. Chemical reaction between the binders and the in-situ soils stabilizes the mixed mass and increases
its strength. By positioning the improved elements properly, we can create thepurpose-fitting improved ground. DJM is the representative deep soil mixing methodthat doesn’ t need mixing water. In comparison with European methods with similar

There is a Case that the Bracing is Not Preferable

The Packer-Equipped Reinforcement Material Grabs Firmly

Anchor is used instead of bracing for excavation support at urban area. Its pulling resistance will undertake the reaction by the bracing. Anchor is advantageous if alignment ofretaining walls is complicated or ground surface is inclined.
There are two types of temporary anchors, removal type that removes tensile materials
after excavation and construction of structure, and left-in-place type that leaves thetensile material as is.
At removal type anchor, a loop-shaped bent un-bonded PC stranded wire combinedwith anchor body is mostly used. After completion of the utilization, the PC strand wireis easily removed.

This is the earth reinforcement method by inserting many short reinforcements
equipped with bag-shaped packers into ground. Large pulling resistance is produced byinjecting grout into the packers. And secure anchorage even at ground where grout
easily runs off, such as gravel or talus cone, is performable. This method has higher
reinforcing effect comparing with the conventional methods and needs fewer reinforcing
materials for stabilizing excavation surface or slope.
By evaluating the advantages and scopes of this method, we can use this method tomore important slopes or structures.
