Anti-floating and anti-sinking steel casing, cofferdam and construction method
The invention relates to an anti-floating and anti-sinking steel casing, a cofferdam and a construction method, and relates to the technical field of bridge construction. The anti-floating and anti-sinking steel casing comprises a steel casing body, a fixed connecting piece, a pulling and pressing rod, an anti-floating bracket and an anti-sinking bracket. Due to the fact that the pulling and pressing rod has large rigidity in anti-floating and anti-sinking of the cofferdam under the wave condition, the pulling and pressing rod can be used as a main force transmission component, the huge upward buoyancy force of water can be effectively transmitted to the anti-floating bracket, and the huge vertical load in a bearing platform construction process is transmitted to the anti-sinking bracket, that is, the anti-floating bracket and the anti-sinking bracket consume part of the upward buoyancy force and the vertical load correspondingly, and then the upward buoyancy force and the sinking force borne by the cofferdam can be reduced, so that the steel casing structure of the cofferdam and the dead weight of bottom sealing concrete can resist small buoyancy, the bond stress between the bottom sealing concrete and the steel casing of a pile foundation can resist small sinking force, the stability of the cofferdam is guaranteed, the problems that the cofferdam floats upwards and a construction bearing platform inclines are solved, and the safety of the construction process is improved.
本申请涉及一种抗浮沉的钢护筒、围堰及施工方法，涉及桥梁建设施工技术领域，包括钢护筒本体、固定连接件、拉压杆、抗浮牛腿和抗沉牛腿，由于拉压杆在围堰处于波浪条件下的抗浮、抗沉中具有较大的刚度，可作为主要的传力构件，其可将水的巨大上浮力有效的传递至抗浮牛腿处，并将承台施工过程中的巨大竖向荷载传递至抗沉牛腿处，即由抗浮牛腿和抗沉牛腿分别消耗部分的上浮力和竖向荷载，进而可减小围堰所受到的上浮力和下沉力，使得围堰的钢护筒结构及封底混凝土的自重可抵抗较小的浮力且封底混凝土与桩基钢护筒间的握裹力也可抵抗较小的下沉力，保证了围堰的稳定性，避免了围堰出现上浮、施工承台倾斜的问题，提高了施工过程的安全性。
