The Liquefied Stabilization Method And Stability Research For River Sludge

The liquefied stabilization method of river sludge is also belongs to a way of solidification for river sludge,which used stabilization technology to decree the water content,degrade the density and strength of sludge and so many characteristics of physics, mechanical and engineering to be satisfied for ordinary earthwork materials, or takes it as the building materials directly raw material use.Compares to ordinary ground treatment methods, the liquefied stabilization method has the process simply, the pilot process to be few, the cost low, the applicable scope is broad, construction convenience and so on quite prominent merit, may widely use in the general structure backfill project domains and so on processing, narrow region construction, underground trench or underground empty recharge, regarding enhances the river course silt the comprehensive utilization efficiency, to reduce the production cost, the improvement application property and so on to have the good significance and the application prospectThis article prime task is as follows:(1) Liquefied stabilization method researchThe liquefied stabilization method is using the river sludge's high watery characteristic, further adjusts the sludge's water content again, then mixed with solidification materials in the foundation, causes the processing mud maintains certain fluidity, and using this nature to the region which needs to backfill or recharge processing. During this process, to cause the processing mud both maintains the good fluidity, and satisfies the construction period and the lifetime quality requirement, then needs to carry on the optimization design to the fluidization processing mixture ratio, according to the sludge's natures, proposed reasonable, suitable liquefied stabilization method(2) Construction period investigation into stabilityWhen carries on the construction using the liquefied stabilization sludge, its construction period's stability essential should be under strictly control, otherwise, it will affects the stabilization sludge later period's quality and the durability greatly. As a result of stabilization material for high water content sludge and cement, between two materials'mutual fusions and supplementary are very important, refers to the related construction technique regulations and find that the construction period processing mud's fluidity, bleeding, filling and so on stabilities need to be controlled, for those reasons we will take some researches on the stability.(3) Using period investigation into stabilityThe liquefied stabilization sludge material takes as a new earthwork material, its application scope as well as the prospect key is decided by stabilization sludge's each nature of using period. In the operational phase, the stabilization sludge's stability will have the influence to the structure stability, stabilization sludge's strengths and its influencing factors, the destruction characteristic, the compressibility, shrinkage and so on will decide the stabilization sludge's reliability and using scope, therefore, we must take researches on the essential properties of using period.
