Steel trestle double-wall steel cofferdam transportation and rapid assembling and lowering construction method
The invention relates to a steel trestle double-wall steel cofferdam transporting and rapid assembling and lowering construction method. The method comprises the steps that firstly, a steel trestle is erected; secondly, the wall body of the double-wall steel cofferdam is prefabricated and machined in a blocking mode; thirdly, the steel casing used in pile foundation construction is lengthened; 4, erecting and assembling a bracket on the steel casing by using profile steel at the height of the steel casing close to the water surface; fifthly, the steel cofferdam is transported to the site in a blocking mode through a steel trestle, and a bottom section cofferdam is assembled on the assembling support; sixthly, a lowering system is installed on the top of the steel casing; seventhly, the bottom section cofferdam is integrally lifted, and the assembling supports are dismantled; eighthly, the bottom section cofferdam is integrally lowered, and the bottom section cofferdam automatically floats on the water surface; ninthly, the wall body of the upper section cofferdam is hoisted in a blocking mode, and the upper section cofferdam is heightened on the bottom section cofferdam; and tenthly, water is injected into the cofferdam to sink to the designated elevation. The large-scale double-wall steel cofferdam assembling and lowering precision and convenience are improved, and the large-scale double-wall steel cofferdam assembling and lowering method has specific application scenes and belongs to the technical field of building construction.
本发明涉及一种钢栈桥双壁钢围堰运输和快捷拼装下放施工方法，包括：步骤一：搭设钢栈桥；步骤二：分块预制加工完成双壁钢围堰壁体；步骤三：接长桩基施工使用过的钢护筒；步骤四：在钢护筒近水面高度处，在钢护筒上用型钢搭设拼装支架；步骤五：利用钢栈桥将钢围堰分块运输至现场，在拼装支架上拼装底节围堰；步骤六：钢护筒顶部安装下放系统；步骤七：整体提升底节围堰，拆除拼装支架；步骤八：整体下放底节围堰，底节围堰自浮于水面；步骤九：分块吊装上节围堰壁体，在底节围堰上接高上节围堰；步骤十：围堰内注水下沉至指定标高。本发明提高了大型双壁钢围堰拼装下放的精准度和便捷性，具有特定应用场景，属于建筑施工技术领域。
