Is It Safe To Rebuild The Plant After The Tidal Flat Area Is Solidified？

How to build factories on tidal flats? This is a difficult but achievable thing to solve. Some people may think, why bother to build on tidal flats? Can't you find a place with a stable foundation to build it? The person who asked these questions actually made an assumption in advance, that is, it is very difficult to turn the tidal flat into a bearing-capable foundation.
But is this really the case? What if there was a way to make tidal flat curing simple and efficient? The soil stabilization system provided by Yichen can solidify the soft ground such as tidal flats and swamps well, making it a stable base with a certain bearing capacity. On this base layer, large machinery such as excavators can enter the site for construction without the risk of subsidence. Bridges, houses, roads and other buildings can also be built on this base in the future, which has a very good application prospect.
We carried out actual construction at a second-line seawall in Keqiao District, Shaoxing City. It is located in the tidal flat area by the Qiantang River, very close to the river embankment, and the soil has a high water content, so it is impossible to build a factory building on this foundation. In order to ensure construction safety, the foundation needs to be solidified first to make it a foundation with a certain bearing capacity that meets the construction requirements. According to the previous environmental survey, we finally provided 5 sets of soil stabilization systems for in-situ solidification of a total of 200,000 cubic meters of silt. The whole project uses a 6-meter mixing head, and the curing depth can reach 5 meters. The power mixer is usually installed on the excavator and operated by the driver of the excavator.
The working principle of the soil stabilization system is that the stirred liquid curing agent is delivered to the front-end power mixer by pumping. The driver of the excavator controls the power mixer to rotate deep into the ground and spray the curing agent. After the curing agent is fully mixed with the silt, a A series of reactions fix a large amount of free water in the soil in the form of crystal water. The engineering properties of the soil can be changed, and the solidified soil is easy to compact and stabilize, reaching a density that cannot be achieved by conventional methods. At present, factory buildings have been built on the cured tidal flats, which are indistinguishable from ordinary foundations. If you want to ask if there is any safety guarantee, isn't this factory building the best proof?
