超软吹填土地基高承载力处理施工工艺

Construction Technologies of Extra Soft Dredger Fill Foundation High Bearing Capacity

吹填淤泥成陆后,场地基本无承载能力,为了快速达到道路区承载力标准,满足道路区路基施工要求,先利用浅层无砂垫层真空预压处理技术,实现浅层吹填淤泥土的快速排水固结,形成具有一定承载能力的硬壳层,然后采用水力输送方式在场地均匀铺设一层砂垫层,再利用深层真空预压技术实现对地基浅层和深层的进一步固结,从而达到道路区高承载力要求的标准。

After dredger fill blowing into land,the site has no bearing capacity. In order to meet the construction requirements of road bed in the road area,the vacuum preloading technology of superficial layer without sand layer is used to meet the requirements of road bed construction to Achieve rapid drainage consolidation of shallow land reclamation silt soil,form a certain bearing capacity of the mantle layer,then adopts hydraulic transmission mode in the field even laid a layer of sand cushion,reuse deep vacuum preloading technology to further consolidation of the foundation of shallow and deep,so as to achieve high bearing capacity requirements of the standard road area.
