众所周知，水泥搅拌桩是以水泥做为固化剂，利用搅拌桩机将水泥喷入土体并充分搅拌，从而实现软基固化。上面提到软土原位固化技术的原理和它类似，仅有些许区别。这个区别主要在于用到的固化剂，原位固化技术用到的固化剂要更加遵循科学的配比，成分不再是单一的水泥，而是在其中添加了粉煤灰、石灰等材料。固化剂的配比经过科学的计算，针对现场需要固化的软基设计，能达到最佳的固化效果。另一个显著的不同在于，二者适用的设备不同。水泥搅拌桩用的是搅拌桩机，原位固化用的搅拌头。搅拌头安装在挖掘机上进行，因此哪里需要固化就可将挖掘机开到哪里，十分的灵活机动。
As is well known, cement mixing piles use cement as a solidifying agent, and use a mixing pile machine to spray cement into the soil and mix it thoroughly, thereby achieving soft foundation solidification. The principle of in-situ solidification technology for soft soil mentioned above is similar to it, with only slight differences. The main difference lies in the curing agent used. The curing agent used in in-situ curing technology should follow a more scientific ratio, and the composition is no longer a single cement, but adds materials such as fly ash and lime to it. The ratio of curing agent is scientifically calculated and designed for the soft foundation that needs to be cured on site, which can achieve the best curing effect. Another significant difference is that the two are suitable for different devices. The cement mixing pile uses a mixing pile machine and a mixing head for in-situ solidification. The mixing head is installed on the excavator, so the excavator can be driven wherever solidification is needed, which is very flexible and mobile.
具体是怎么操作的呢?首先，我们要取样泥进行分析，根据软土的特点及施工要求，并参考当地就地取材的价格成本确定固化剂成分、配比及总掺量，做到保证固化效果的同时降低原料成本。接下来我们要进行固化前准备，对固化区域进行抽排水，一般采用围堰法或挖集水井排水法。然后再进行小面积试验施工，检测固化前后的含水率和抗压强度，从而最终确定固化剂成分。完成以上步骤后，就可以开始正式施工。
How is it operated specifically? Firstly, we need to take samples of mud for analysis. Based on the characteristics of soft soil and construction requirements, and referring to the price and cost of locally sourced materials, we will determine the composition, ratio, and total dosage of the curing agent to ensure the solidification effect while reducing the cost of raw materials. Next, we need to prepare before solidification and carry out drainage in the solidification area, usually using the cofferdam method or digging a collection well for drainage. Then, small-scale experimental construction is carried out to test the moisture content and compressive strength before and after solidification, in order to ultimately determine the composition of the curing agent. After completing the above steps, formal construction can begin.
正式施工后，我们只需要将固化剂配比输入智能配比工作台，一键启动，工作台便会将粉料仓内的原料按照预先设定的比例混合，再添加水，形成湿浆固化剂。合成的固化再通过软管输送至前端搅拌头，这一系列操作都是由电脑直接控制的，全自动操作，无需人工。操作人员只需要驾驶安装着搅拌头的挖掘机，将搅拌头深入软土中喷洒固化剂并进行搅拌。施工全程还有GPS定位，了解每台挖机的位置，宏观把控固化进度。
After the formal construction, we only need to input the curing agent ratio into the intelligent mixing workbench. With just one click, the workbench will mix the raw materials in the powder bin according to the pre-set ratio, and then add water to form a wet slurry curing agent. The synthesized curing is then transported to the front mixing head through a hose, and this series of operations are directly controlled by a computer, fully automatic, and do not require manual labor. The operator only needs to drive the excavator with a mixing head installed, spray the solidifying agent deep into the soft soil, and stir it. GPS positioning is also provided throughout the construction process to understand the position of each excavator and macroscopically control the solidification progress.
