Double-wall steel cofferdam construction method suitable for complex conditions
The invention provides a double-wall steel cofferdam construction method suitable for complex conditions. The double-wall steel cofferdam construction method comprises the steps that S1, a double-wall steel cofferdam is split into block units; s3, a first section of steel cofferdam is assembled; s4, jacks are arranged to form a force bearing system corresponding to the bearing steel cofferdam; and S5, the steel cofferdam is divided into multiple sections, the multiple sections of steel cofferdams are sequentially assembled and lowered, concrete is poured into the wall bin during lowering, so that the cofferdam sinks to the preset position, mud suction sinking continues to be conducted after the cofferdam is implanted, and the construction efficiency is effectively improved.
本发明提供一种适用于复杂条件下双壁钢围堰施工方法，步骤S1，将双壁钢围堰拆分成块单元，步骤S2，进行钢管桩插打；步骤S3，进行第一节钢围堰拼组；步骤S4，设置千斤顶构成对应承载钢围堰的承力系；步骤S5，钢围堰分为多节，依次对多节钢围堰进行拼装和下放，在下放时通过向壁仓内灌注混凝土使围堰下沉至预设位置，在围堰着床后继续进行吸泥下沉，有效提高了施工效率。
