Steel pipe structure cofferdam and construction method thereof
The invention discloses a steel pipe structure cofferdam and a building method thereof. The cofferdam comprises a steel pipe frame, a breast board, waterproof cloth and a plurality of counterweight sand bags. The steel pipe frame comprises multiple pairs of supporting steel pipes, horizontal transverse steel pipes and multiple horizontal longitudinal steel pipes. Each pair of supporting steel pipes are obliquely connected in a crossed manner; the multiple pairs of supporting steel pipes are arranged in parallel at intervals in the axis direction of the cofferdam, and the lower portions of each pair of supporting steel pipes are inserted into a river bottom soil body. The horizontal transverse steel pipe comprises an upper horizontal transverse steel pipe arranged at the intersection point of the multiple pairs of supporting steel pipes and lower horizontal transverse steel pipes arranged between the waists of the multiple pairs of supporting steel pipes in a one-to-one correspondence mode; the plurality of horizontal longitudinal steel pipes are bridged between the pair of lower horizontal transverse steel pipes at intervals along the axis direction of the cofferdam; the soil retaining plate covers the upstream face of the steel pipe frame; the waterproof cloth covers the soil retaining plate; and the plurality of counterweight sand bags are pressed on the waterproof cloth at the river bottom part at intervals along the axis direction of the cofferdam. The device is simple in structure, firm, stable and convenient and fast to assemble and disassemble.
本发明公开了一种钢管结构围堰及其搭建方法，围堰包括钢管架、挡土板、防水布和多个配重砂袋。钢管架包括多对支撑钢管、水平横向钢管和多根水平纵向钢管；每对支撑钢管均呈斜向地交叉连接；多对支撑钢管沿围堰的轴线方向间隔地平行设置，每对支撑钢管的下部插入河底土体中；水平横向钢管包括一根设在多对支撑钢管的相交点的上水平横向钢管和一对一一对应地设在多对支撑钢管的腰部之间的下水平横向钢管；多根水平纵向钢管沿围堰的轴线方向间隔地跨接在一对下水平横向钢管之间；挡土板覆盖在钢管架的迎水面上；防水布覆盖在挡土板上；多个配重砂袋沿围堰的轴线方向间隔地压在位于河底部分的防水布上。本发明的结构简单，牢固稳定，装拆方便快捷。
