Construction method of CFG pile composite foundation mattress layer
The invention provides a construction method of a CFG pile composite foundation mattress layer, and relates to the technical field of building construction.The construction method of the CFG pile composite foundation mattress layer comprises the steps that each CFG pile cap construction area is excavated to a certain range below the elevation position of the bottom of a CFG pile cap according to the pile cap excavation range; concrete is poured into the construction area of the CFG pile cap to the elevation position of the bottom of the CFG pile cap, and a pile cap cushion layer is formed after the concrete is hardened; the geotechnical steel-plastic grating is laid within the depth range of the area where the flexible composite mattress layer is constructed, flow-state solidified soil prepared in advance is poured into the area where the flexible composite mattress layer is constructed, and the flow-state solidified soil is formed by mixing and stirring a rock-soil solidifying agent and engineering muck mud according to a certain proportion. Compared with the prior art, the construction method of the CFG pile composite foundation mattress layer has the advantages that the original pressure bearing effect of the composite foundation is not changed, and meanwhile, the composite foundation has certain anti-seepage and anti-floating effects.
本发明提供了一种CFG桩复合地基褥垫层的施工方法，涉及建筑施工技术领域，CFG桩复合地基褥垫层的施工方法包括根据桩帽开挖范围对每个CFG桩桩帽施工区域进行开挖至CFG桩桩帽底部标高位置以下一定范围；向CFG桩桩帽施工区域浇筑混凝土至CFG桩桩帽底部标高位置，待其硬化后形成桩帽垫层；将土工钢塑格栅铺设在施做柔性复合褥垫层区域的深度范围内，并向施做柔性复合褥垫层区域浇筑提前制备的流态固化土，其中流态固化土由岩土固化剂和工程渣土泥浆按照一定比例混合搅拌而成。本发明的CFG桩复合地基褥垫层的施工方法，相比于现有技术，在不改变复合地基原本具有的承压作用的同时，还能使得复合地基兼具一定的防渗和抗浮作用。
