Underwater ultra-soft clay gravel pile composite foundation construction pretreatment method
The invention discloses a pretreatment method for construction of an underwater ultra-soft clay gravel pile composite foundation. The pretreatment method comprises the steps that S1, the undrained strength of soft clay needed for pile forming is calculated; s2, calculating the thickness and the treatment time of the sand cushion layer; s3, a self-propelled belt ship is matched with a flat barge to position and construct an underwater sand cushion, and a special overwater plastic row ship is adopted to construct a drainage plate; s4, the reinforcing effect is detected through the cross plate drainage plate, and whether the gravel pile construction condition is met or not is judged; and S5, if yes, gravel pile overwater construction is carried out. The bearing capacity and stability of the foundation can be effectively improved, and the method is suitable for foundation reinforcement in underwater ultra-soft clay areas.
本发明公开了一种水下超软黏土碎石桩复合地基施工预处理方法，包括：步骤S1，计算成桩所需软黏土的不排水强度；步骤S2，推算砂垫层厚度和处理时间；步骤S3，采用自航皮带船配合平板驳定位施工水下砂垫层，采用专用水上塑排船施工排水板；步骤S4，通过十字板排水板检测加固效果，判断是否满足施工碎石桩的条件；步骤S5，若满足，则进行水上施工碎石桩。本发明能够有效提高地基的承载能力和稳定性，适用于水下超软黏土地区的地基加固。
