Steel cofferdam positioning device and design method
The invention discloses a steel cofferdam positioning device and a design method, and relates to the field of bridge construction, the steel cofferdam positioning device comprises a positioning platform, a steel pipe pile foundation and a cable pulling assembly, the positioning platform comprises a trestle located on the downstream side of a set position and a construction platform connected with the trestle and located on the outer side of the set position; the steel pipe pile foundations comprise a plurality of first steel pipe pile foundations used for supporting the trestle and arranged in the longitudinal direction of the trestle and a plurality of second steel pipe pile foundations used for supporting the construction platform and arranged in the transverse direction of the trestle, each first steel pipe pile foundation comprises an inclined strut located on the downstream side of the trestle, and the included angle between the inclined strut and the vertical direction is a set angle; the cable pulling assembly is arranged on the positioning platform and used for pulling the steel cofferdam to a set position. The included angle between the inclined strut and the vertical direction is the set angle, so that the trestle can be better supported, the steel cofferdam is prevented from impacting the steel pipe pile foundations and the positioning platform, and the horizontal load bearing capacity of the first steel pipe pile foundation is improved.
本发明公开了一种钢围堰定位装置及设计方法，涉及桥梁施工领域，该装置包括定位平台、钢管桩基础和拉缆组件，定位平台包括位于设定位置下游侧的栈桥，及与栈桥连接且位于设定位置外侧的施工平台；钢管桩基础包括用于支撑栈桥且沿栈桥纵桥向布置的多个第一钢管桩基础，及用于支撑施工平台且沿横桥向布置的多个第二钢管桩基础，第一钢管桩基础包括位于栈桥下游侧的斜撑，斜撑与竖直方向的夹角呈设定角度；拉缆组件设在定位平台上，用于牵引钢围堰至设定位置。通过使斜撑与竖直方向的夹角呈设定角度，从而可以更好地支撑栈桥，防止钢围堰对钢管桩基础及定位平台造成冲击，提高了第一钢管桩基础的水平荷载承载能力。
