一种钢围堰下沉导向装置
摘要：
本实用新型公开了一种钢围堰下沉导向装置，包括钢护筒、设置在钢护筒结构外围的钢围堰，所述的钢护筒与钢围堰之间设有导向限位钢管。采用上述结构，本实用新型具有以下优点：增加了钢围堰导向的刚度，提高了钢围堰抵抗偏位的能力，保证了钢围堰下沉定位的精度，尤其适用于在强涌潮区域等复杂水文条件下下沉钢围堰。采用插打钢管桩作为限位导向，提高了钢围堰下沉过程中导向的刚度，提高了钢围堰或沉井在复杂水文条件下抵抗倾覆的能力。
摘要（英）：

The utility model discloses a steel cofferdam sinking guide device which comprises a steel casing and a steel cofferdam arranged on the structural periphery of the steel casing. A guide limiting steel pipe is arranged between the steel casing and the steel cofferdam. Due to the adoption of the structure, the steel cofferdam sinking guide device has the following advantages that the guide stiffness of the steel cofferdam is improved; the deviation resistance of the steel cofferdam is improved; the accuracy of positioning the sinking of the steel cofferdam is ensured; and the steel cofferdam sinking guide device is particularly suitable for sinking the steel cofferdam under the complex hydrologic conditions such as in a strong tidal bore region. An inserted steel pipe pile is used as a limiting guide part, so that the guide stiffness of the steel cofferdam in the sinking process is improved and the deviation resistance of the steel cofferdam or an open caisson under the complex hydrologic conditions is improved.
