Note. The stabilized soil mixing machine improves its mechanical properties and physical properties by mixing the stabilized soil material with a binder (such as filler, cement, lime, etc.) or filler. performance. 3.2 Tractor tractor A vehicle that carries all the components and tow the mixing device when working and when transferring between construction sites. 3.3 Mixing device A device consisting of moving parts that perform in-situ processing (such as stirring or dispersing) of stabilized earth material. Note. The mixing device usually consists of a power-driven rotor equipped with a cutter, which rotates during the mixing operation (see Appendix A, Figure A.1 ~ (Figure A.5). Another type of mixing device uses special cutters to reciprocate during mixing operations (see Figure A.6). 3.4 Variablemixerchamber The mixing chamber equipped with gates or pleats can control the mixing time of materials in the mixing chamber. ...... |
