一种加快钢围堰组件下沉速度的吸泥方法
摘要：
本发明提供一种应用于桥梁基础施工技术领域的加快钢围堰组件下沉速度的吸泥方法，多个钢围堰(1)组成圆型或方形的钢围堰组件(2)，所述的钢围堰组件(2)在泥面(3)上进行下沉时，钢围堰组件(2)内侧的钢围堰内刃脚(4)部位设置多个吸泥管(5)，通过多个吸泥管(5)对钢围堰内刃脚(4)部位进行吸泥。本发明的加快钢围堰下沉速度的吸泥方法，克服了现有的钢围堰组件下沉过程中采用的吸泥方法吸泥方量大，下沉时间长的缺点，本发明的方法，吸泥方量较少，钢围堰组件下沉速度快，用时短且花费较少。
摘要（英）：

The invention provides a sludge suction method capable of accelerating the sinking speed of a steel cofferdam assembly, which is applied to the technical field of bridge foundation construction. A plurality of steel cofferdams (1) form a round or square steel cofferdam assembly (2). When the steel cofferdam assembly (2) sinks on a sludge surface (3), a plurality of sludge suction pipes (5) are arranged at cutting edges (4) of the steel cofferdams at the inner side of the steel cofferdam assembly (2) and are used for sucking sludge from the cutting edges (4) of the steel cofferdams. The sludge suction method capable of accelerating the sinking speed of the steel cofferdam assembly overcomes the defects that the sludge suction volume is large and the sinking time is long in the sludge suction method adopted in the sinking process of the traditional steel cofferdam assembly. The method provided by the invention has the advantages of smaller sludge suction volume, fast sinking speed of the steel cofferdam assembly, short time and lower cost.
