Foundation treatment method of pile-foundation-free chimney suitable for silt-shaped dredger fill
The invention discloses a foundation treatment method of a pile-foundation-free chimney suitable for sludge-shaped dredger fill soil, relates to the technical field of foundation construction methods, and solves the problems that a pile driver and a prefabricated concrete pile are needed for an existing single pile or multiple piles, the time is long, the cost is high, the site requirement for a site is high, and a large construction space is needed. Comprising the following steps that S10, excavation is conducted according to a chimney foundation until the top of silt-shaped dredger fill is reached; s20, gravel is firstly filled, the gravel is rammed into the surface layer of the silt-shaped dredger fill, and a flexible cushion-like layer is formed on the top of the dredger fill; s30, soil body replacement filling is conducted on the upper portion of the cushion-like layer, a replacement filling layer is formed, and the replacement filling layer comprises compacted soil bodies and/or pebbles; and S40, a concrete cushion layer is constructed on the replacing and filling layer. No pile foundation construction can be conducted on site, concrete piles do not need to be purchased, pile drivers do not need to be rented, only common engineering machines such as an excavator are needed, and the effects of effectively reducing foundation treatment cost, saving cost and reducing labor intensity are achieved.
本发明公开了一种适用于淤泥状冲填土质上的无桩基烟囱的地基处理方法，涉及地基施工方法技术领域，解决了现有的单桩或者多桩需要打桩机和预制好的混凝土桩，时间长，成本高，对现场的场地要求高，需要较大的施工空间等问题。包括如下步骤，步骤S10，根据烟囱基础开挖至淤泥状冲填土顶；步骤S20，先填碎石，将碎石夯入淤泥状冲填土表层中，在冲填土顶部形成一种柔性的类垫层；步骤S30，在类垫层上部进行土体换填，形成一层换填层，换填层包括压实土体和/或石子；步骤S40，在换填层上施工混凝土垫层。能现场无桩基施工，无需购置混凝土桩和租用打桩机，只需要挖机等常用工程机械，达到了有效降低地基处理费用、可节省成本和降低劳动强度的效果。
