The invention provides a cofferdam bottom gushing water blocking method, and relates to the technical field of bridge construction. The method comprises the steps that a grouting point is determined based on a water gushing point of water gushing at the bottom of the cofferdam, and the grouting point is selected with the water gushing point as the center; a steel sleeve extending upwards is fixed to the grouting point; a steel sleeve is used for guiding the drilling machine to penetrate through the bottom sealing concrete to form grouting holes; and after the inner horizontal plane and the outer horizontal plane of the cofferdam are flush, a coagulant is injected from the grouting holes in a pressing mode to solidify a soil layer below the bottom sealing concrete, and water gushing plugging is achieved. According to the embodiment of the invention, after water bursting occurs at the bottom of the cofferdam, water bursting blocking operation can be rapidly carried out without waiting for water returning of the cofferdam, the water bursting blocking speed is high, the influence of water bursting on the cofferdam construction period is effectively reduced, the construction cost is reduced, and smooth proceeding of bridge engineering construction is promoted.
本申请提供了一种围堰底部涌水封堵方法，涉及桥梁施工技术领域。该方法包括：基于围堰底部涌水的涌水点确认注浆点，注浆点以涌水点为中心进行选择；在注浆点固定向上延伸的钢套管；利用钢套管引导钻机贯穿封底混凝土形成注浆孔；待围堰的内外水平面平齐之后，从注浆孔压注凝固剂以固化封底混凝土下方的土层，实现涌水封堵。本申请实施例能够在围堰底部出现涌水后，快速进行涌水封堵操作，无需等待围堰回水，涌水封堵速度快，有效降低涌水对围堰施工工期的影响，降低施工成本，促进桥梁工程建设的顺利推进。
