Steel pipe pile cofferdam construction method
The invention relates to the technical field of cofferdam construction methods, and discloses a steel pipe pile cofferdam construction method which comprises the following construction steps: A, arranging a guide frame; b, inserting and driving steel pipe piles; c, correcting the deviation of the steel pipe pile; d, closure; e, the steel pipe piles are filled with sand and concrete; and F, leaking stoppage and water stopping. The waterproof cloth bag is arranged in the lock catch groove, concrete is grouted into the waterproof cloth bag through the grouting pipe, direct contact between the concrete and water is avoided, slurry is prevented from being scattered under water, grouting is easier, multiple times of grouting are not needed, and the concrete can be well solidified in the lock catch through one-time grouting; and the labor intensity of operators is relieved, the operation cost is reduced, and therefore the problems that in the prior art, concrete poured in the lock catch is prone to being scattered underwater, pouring is difficult, and the water stop construction cost is high are solved.
本发明涉及围堰施工工法技术领域，公开了一种钢管桩围堰施工方法，包括以下施工步骤：A、设置导向框；B、钢管桩插打；C、钢管桩纠偏；D、合龙；E、钢管桩内灌砂及混凝土；F、堵漏止水。本发明通过防水布袋，将防水布袋放置到锁扣凹槽内，使用注浆管将混凝土注浆在防水布袋内，避免混凝土与水直接接触，从而防止浆液在水下被冲散，灌浆更加容易，无需多次注浆，一次注浆即可使得混凝土较好地凝固在锁口内，减轻了操作人员的劳动强度，降低了操作成本，从而解决现有技术中存在锁扣内灌注混凝土容易在水下被冲散，灌注较为困难，止水施工成本较大的问题。
