Feasibility Analysis Of Solidification Technology Based On Marine Coral Sand Layer

Coral sand curing technology feasibility study comes from sandy layer grouting technology belong to the category of foundation treatment. Grouting process combining the fluid mechanics,soil mechanics,mechanical engineering disciplines. In the coral sand grouting solidification process of application is less, and the corresponding construction method and grouting material data is not perfect, in the far away from the coast in the coral sand solidification technology has certain feasibility. From the founding of the early national preliminary exploration of the ocean development, to the peak of the development of the country into the sea areas in the twenty-first century,countries in the development of the south China sea is a brand new stage, a lot of reports and articles have wrote about the south China sea, rely on coral reefs for artificial blowing sand island,are used to strengthen the soft foundation. At the same time, in the process of rapid reclamation, there is also a lot of potential safety hazard. Coral sand belongs to a special type of rock and soil type,affected by the Marine hydrodynamic effect, complex geological structure,engineering geological conditions is poorer, such land reclamation compaction under the condition of the same against wartime repair scrambling to work; Under the water, tidal action, the loose sand body will get better play, does not favor the reef body stability of the base surface. Most domestic literature and specification is grouting technology in the concrete dam construction, but the use of cement grouting consolidation coral sand on the sea for the embankment and slope control provide certain feasibility of literature, the coral sand curing process in the practical application of lag, in most cases the construction rely on the experience of the grouting construction, easy to cause construction costs and the grouting effect is not ideal, likely strong concealment engineering hidden danger, and lead to engineering accident. Study of coral sand layer grouting construction, the author created a itself can simulate the coral sand strata grouting reinforcement test equipment to test and verify its feasibility in coral sand micro soil grouting in the study.
