Strengthening treatment method for heavy liquefied foundation in coastal shoal backfill area
The invention discloses a coastal shoal backfill area heavy liquefied foundation reinforcement treatment method which comprises the following steps: 1, surveying and setting out, determining a vibroflotation construction area, and leveling a site; 2, setting vibroflotation parameters; 3, the vibroflot is positioned to the vibroflot point position and sinks, and vibroflot compaction hole forming is achieved; 4, the vibroflot stays vibration at the bottom of the hole; 5, the vibroflot is pulled up slowly to the hole opening, and vibration is reserved at the hole opening; 6, entering a technical interval after the vibroflotation compaction is completed; 7, detecting the standard penetration of the soil layer after the technical interval is finished; 8, measuring and paying off the long spiral cast-in-place pile and positioning a pile machine; 9, drilling a pile machine into a soil layer and performing pressure irrigation to form a pile; 10, soil between the long spiral cast-in-place piles is removed, and pile heads are broken; 11, laying a mattress layer to form a long spiral cast-in-place pile composite foundation; and 12, the bearing capacity of the long spiral cast-in-place pile composite foundation is detected through the bearing plate. The problems that in the prior art, construction efficiency is low, cost is high, the pollution reworking period is long, and only surface foundation reinforcement is achieved can be solved.
本发明公开了一种滨海浅滩回填区重液化地基加固处理方法，包括步骤：1：测量放线，确定振冲施工区域，场地平整；2：设定振冲参数；3：将振冲器定位至振冲点位并下沉，实现振冲挤密成孔；4：振冲器在孔底留振；5：慢速上拔振冲器至孔口处并在孔口处留振；6：振冲挤密完成后进入技术间歇；7：技术间歇结束后进行土层标准贯入度检测；8：长螺旋灌注桩测量放线及桩机定位；9：桩机钻进土层并压灌成桩；10：清除长螺旋灌注桩间土，并破除桩头；11：铺设褥垫层，形成长螺旋灌注桩复合地基；12：通过承压板进行长螺旋灌注桩复合地基的承载力检测。本发明能解决现有技术中施工效率低、成本高、污染重工期长和仅达到表面地基加固的问题。
