Deviated pile processing method
The invention relates to a deviated pile processing method. The deviated pile processing method comprises the following steps that step 1, completeness of deviated piles is judged, the piles are divided into piles I, piles II and piles III through a low-strain reflection wave method, the piles I are piles without pile body defects, the piles II are piles with basically complete pile bodies, and the piles III are piles with incomplete pile bodies; step 2, the piles I and the piles II of which the deviation values are not greater than 1/20 of the thickness of the muddy soil layer are selected; and step 3, foundation bottom plates with the thickness not smaller than 400mm are arranged at the tops of the piles, and the horizontal thrust of the deviated piles is resisted. According to the deviated pile processing method, the foundation bottom plates with the thickness not smaller than 400mm are arranged at the tops of the deviated piles of which the deviation values are not larger than 1/20of the thickness of the mucky soil layer, the rigidity of the foundation bottom plates is used for resisting the horizontal thrust of the deviated piles, no special process is needed for the deviatedpiles of which the deviation values are not larger than 1/20 of the thickness of the mucky soil layer, and good popularization prospects are achieved.
本发明涉及一种偏桩的处理方法，包括以下步骤，步骤一：偏桩的完整性判断，利用低应变反射波法将桩分为Ⅰ类桩、Ⅱ类桩和Ⅲ类桩，所述Ⅰ类桩为桩身无缺陷的桩，Ⅱ类桩为桩身基本完整的桩，Ⅲ类桩为桩身不完整的桩；步骤二：挑选偏位值不大于淤泥质土层厚度的1/20的Ⅰ类桩和Ⅱ类桩；步骤三：在桩顶处设置厚度不小于400mm的基础底板，抵制偏桩的水平推力。本发明，偏位值不大于淤泥质土层厚度的1/20的偏桩，在偏桩的顶部设置有厚度不小于400mm的基础底板，利用基础底板自身的刚度，抵制偏桩的水平推力，令偏位值不大于淤泥质土层厚度的1/20的偏桩不需要进行特别处理具有很好的推广前景。
