Sandy soil liquefaction foundation treatment method
The invention provides a sand liquefaction foundation treatment method, and relates to the field of foundation construction methods. The sand liquefaction foundation treatment method comprises the following construction steps that S1, construction preparation is conducted, specifically, a construction area is determined, and paying-off and dotting are conducted according to a drawing; S2, a closed area is arranged, specifically, the steel sheet piles are inserted into soil according to the paying-off positions, and the closed area is formed; S3, punching is conducted, specifically, a punching pile driver is used for punching in the closed area according to the dotting position; S4, filling is conducted, specifically, gravel materials are put into the punched holes, and compaction is conducted while filling is conducted to form compaction piles; and S5, rammed earth is manufactured, specifically, dry soil is taken to be crushed and ground into fine sand soil, and the fine sand soil is laid in the closed area and compacted through a road roller to form a rammed earth layer. The closed area is formed by arranging the steel sheet piles to limit the soil, the situation that the carrying capacity of the soil weakens the cohesive force of compaction pile filler is prevented, and the situation that the soil layer density is reduced along with the time effect is advantageously prevented.
本发明提供一种砂土液化地基处理方法，涉及地基施工方法领域。该砂土液化地基处理方法，包括以下施工步骤：S1：施工准备：确定施工区域，并根据图纸进行放线打点；S2：设置封闭区域：将钢板桩按照放线的位置插入土壤中，形成一个封闭的区域；S3：打孔：在封闭的区域内按照打点的位置使用冲孔打桩机进行冲孔；S4：填料：将碎石料投放至打好的孔内，边填料边夯实形成挤密桩；S5：制作夯土：取干燥的泥土进行破碎撵磨成细砂土，铺设在封闭区域内通过使用压路机进行压实形成夯土层。通过设置钢板桩形成封闭区域对土壤进行限定，防止土壤的搬运能力削弱挤密桩填料的凝聚力，有利于防止土层密度会随着时间的作用进行降低。
