Super-large and super-deep steel cofferdam structure suitable for full sand layer and construction method of super-large and super-deep steel cofferdam structure
The invention belongs to the technical field of constructional engineering, and particularly relates to a super-large and super-deep steel cofferdam structure suitable for a full sand layer and a construction method thereof.The super-large and super-deep steel cofferdam structure comprises a steel pipe and a support arranged above the full sand layer, guide rails are symmetrically distributed on the inner side wall of the steel pipe, and a mounting shell is slidably connected to the surfaces of the guide rails in a clamped mode; and a main sand cleaning mechanism is arranged on the upper surface of the mounting shell. According to the steel cofferdam structure suitable for the ultra-large and ultra-deep full sand layer and the construction method of the steel cofferdam structure, by arranging the main sand cleaning mechanism, gravel below the steel pipes can be conveniently cleaned, the steel pipes can be conveniently inserted into the full sand layer, and therefore the resistance borne by the steel pipes extending into the full sand layer is relieved; and mud and sand mixed with water are discharged out of the steel pipe through the second-stage suction pump, the broken sand and sand are discharged, so that the steel pipe is more convenient to insert, and the construction efficiency is improved.
本发明属于建筑工程技术领域，尤其是一种适用于全砂层超大超深的钢围堰结构及其施工方法，包括钢管和设置在全砂层上方的支架，所述钢管的内侧壁呈对称分布设置有导轨，所述导轨的表面滑动卡接有安装壳体，所述安装壳体的上表面设置有主清砂机构。该适用于全砂层超大超深的钢围堰结构及其施工方法，通过设置主清砂机构，便于对钢管下方的砂石进行清理，使得钢管便于插入全砂层内，从而减缓钢管伸入全砂层内受到的阻力，通过一级抽吸泵将破开的砂石从进砂口吸入钢管内，并通过二级抽吸泵将与水混合后的泥砂排出钢管，通过将破开的砂石排出使得钢管的插入更为简便，进而提高施工效率。
